Description

COLLISION RULES FOR MEASUREMENT GAPS

FIELD OF TECHNOLOGY

The following relates to wireless communication, including collision rules for measurement gaps.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .

In some examples, a UE may perform measurements on downlink signals received using one or more target reception bands to determine channel quality metrics of the one or more target reception bands. The UE may perform the measurements during a measurement gap and during this measurement gap, the UE may be unable to receive or transmit on serving bands.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support collision rules for measurement gaps. For example, the described techniques provide for a user equipment (UE) or a network entity avoiding conflict between measurement gaps and transmission band switching periods when the UE is scheduled to transmit consecutive uplink signaling using different transmission bands. In some examples, the network entity may receive first signaling from the UE that indicates capability information associated with the UE. The capability information may indicate a capability of the UE to perform channel quality measurements during a switching period that defines a duration for the UE to switching from transmitting during a first transmission frequency band to transmitting using a second transmission frequency band. Upon receiving the capability information, the network entity may transmit an uplink grant scheduling the UE to transmit first uplink signaling using the first transmission frequency band followed by second uplink signaling using the second transmission frequency band. Based on the uplink grant, the UE may perform the channel quality measurement on the one or more reception frequency bands.

DETAILED DESCRIPTION

In some examples, a user equipment (UE) may perform periodic or aperiodic measurements on downlink signals to determine a channel quality of a target frequency band. The UE may perform the measurements during measurement gaps and during the measurement gap, the UE may not transmit or receive on a serving band. Further, in some examples, a network entity may schedule the UE to transmit consecutive uplink transmissions. A first uplink transmission may occur prior to the measurement gap and a second uplink transmission may occur after the measurement gap. However, in some examples, the UE may utilize different uplink transmission bands to transmit the consecutive uplink transmissions. For example, the UE may transmit the first uplink transmission using a first uplink transmission band and the second uplink transmission using a second uplink transmission band. In such case, the UE may create a switching gap between the consecutive uplink transmission resulting in an overlap between the switching gap and the measurement gap. Currently, there is no guidance on how to handle conflicts between measurement gaps and skipping gaps and in the event of such collision, the UE may experience an error.

As described herein, a set of collision rules may be defined for a UE or a network entity to handle conflicts between switching gaps and the measurement gaps to avoid errors at the UE. In some examples, the UE may transmit capability information indicating whether the UE may perform channel quality measurements during a switching gap associated with switching from a first uplink transmission band to a second uplink transmission band. Upon receiving the capability information, the network entity may transmit an uplink grant scheduling a first uplink transmission using the first uplink transmission band and a second uplink transmission using the second uplink transmission band. If the UE is unable to perform measurements during the switching gap, the network entity may schedule the first uplink transmission and the second uplink transmission such there is a gap between the switching period and the measurement gap. In another example, the UE may drop at least a portion of the first uplink transmission or the second uplink transmission and perform the switching during the portion. Using such methods may allow the UE or the network entity to resolve conflict between measurement gaps and switching gaps.

Aspects of the disclosure are initially described in the context of wireless communications systems. Additional aspects are described in the context of switching schemes and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to collision rules for measurement gaps.

FIG. 1 shows an example of a wireless communications system 100 that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .

The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.

As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.

In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) , one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.

One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140) .

In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .

The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170) . In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.

In wireless communications systems (e.g., wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.

In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support collision rules for measurement gaps as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .

A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.

The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105) .

In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different radio access technology) .

The communication links 125 shown in the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .

A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.

One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.

The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of T_s=1/ (Δf_max·N_f) seconds, for which Δf_max may represent a supported subcarrier spacing, and N_f may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .

Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N_f) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .

Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.

A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.

A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered network entity 105 (e.g., a lower-powered base station 140) , as compared with a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or multiple cells and may also support communications via the one or more cells using one or multiple component carriers.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.

In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.

The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.

The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.

Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .

As described herein, a set of collision rules may be defined such that a UE 115 may avoid conflict between measurement gaps and transmission band switching periods when the UE 115 is scheduled to transmit consecutive uplink signaling using different transmission bands. In some examples, the network entity 105 may receive first signaling from the UE 115 that indicates capability information associated with the UE 115. The capability information may indicate a capability of the UE 115 to perform channel quality measurements during a switching period that defines a duration for the UE 115 to switching from transmitting during a first transmission frequency band to transmitting using a second transmission frequency band. Upon receiving the capability information, the network entity 105 may transmit an uplink grant scheduling the UE 115 to transmit first uplink signaling using the first transmission frequency band followed by second uplink signaling using the second transmission frequency band. Based on the uplink grant, the UE 115 may perform the channel quality measurement on the one or more reception frequency bands.

FIG. 2 shows an example of a wireless communications system 200 that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. In some examples, the wireless communications system 200 may implement aspects of a wireless communications system 100. For example, the wireless communications system 200 may include a UE 115-a which may be an example of a UE 115 as described with reference to FIG. 1. Additionally, the wireless communications system 200 may include a network entity 105-a which may be an example of a network entity 105 as described with reference to FIG. 1.

In some examples, the UE 115-a may be configured with measurement gaps. Measurement gaps may be described as opportunities given to the UE 115-a to perform measurements on downlink signals of target frequency bands. Using the measurements, the UE 115-a may determine a channel quality of each of the target frequency bands which may influence future scheduling. In some examples, the UE 115-a may be unable to perform the measurements while transmitting or receiving (e.g., using a serving frequency band) . As such, the measurement gaps may be configured such that they do not coincide with scheduled transmissions or receptions. As one example, if the network entity 105-a schedules the UE 115-a to transmit a first uplink message followed by a second uplink message, the measurement gap may fall between transmission of the first uplink message and transmission of the second uplink message, but may not overlap with either of the transmission of the first uplink message or the transmission of the second uplink message.

In some examples, the UE 115-a may switch between different frequency bands when transmitting consecutive uplink messages. For example, the UE 115-a may utilize a first frequency band to transmit a first uplink message and may utilize a second frequency band to transmit a second uplink message. The UE 115-a may switch between a minimum of two frequency bands and a maximum of four frequency bands for uplink transmissions. To switch from one frequency band to another frequency band, the UE 115-a may undergo RF tuning. During the RF tuning, the UE 115-a may adapt RF components of the transmission chain such that transmissions using the target frequency band may be possible.

A switching gap may specify a duration during which the UE 115-a performs the RF tuning. However, if a measurement gap is configured between two consecutive uplink transmissions and the UE 115-a is scheduled to transmit the two consecutive uplink transmissions using two different frequency bands, a duration between the measurement gap and either one of the uplink transmissions may not be enough to include the switching gap and as such, the switching gap may overlap with the measurement gaps. In some examples, the UE 115-a may be unable to support RF tuning during the measurement gap and there is no clear guidance or rules regarding how the UE 115-a may handle conflicts between the measurement gap and the switching gap.

As described herein, one or more rules may be put in place for a UE 115-a or a network entity 105-a to handle collisions between measurement gaps and switching gaps. In one example, the UE 115-a may transmit capability information 205 to the network entity 105-a. The capability information 205 may indicate a capability of the UE 115-a to perform channel quality measurements (e.g., during a measurement gap) during a switching gap that defines a duration for the UE 115-a to switch from a first frequency band to a second frequency band. In some cases, a reception chain and a transmission chain of the UE 115-a may not share RF components. As such, the capability information 205 may indicate an ability of the UE 115-a to perform channel quality measurements during the switching gap and in response to the capability information 205, the network entity 105-a may schedule (e.g., using an uplink grant 210) the UE 115-a to transmit consecutive uplink transmissions using different frequency bands as usual (e.g., without taking into account the measurement gap) .

Alternatively, the reception chain and the transmission chain of the UE 115-a may share RF components. As such, the capability information 205 may indicate an inability of the UE 115-a to perform channel quality measurements during the switching gap. In such case, as one option, the network entity 105-a may guarantee that the UE 115-a will not encounter a conflict between the measurement gap and the switching gap. For example, upon receiving the capability information 205, the network entity 105-a may transmit an uplink grant 210 to the UE 115-a scheduling the UE 115-a to transmit a PUSCH transmission 215-a using a first frequency band followed by a PUSCH transmission 215-b using a second frequency band. Between the PUSCH transmission 215-a and the PUSCH transmission 215-b may be a measurement gap. The network entity 105-a may schedule the PUSCH transmissions 215 such that there is a duration between the switching gap (to switch from the first frequency band to the second frequency band) and the measurement gap. By scheduling the UE 115-a in such a way, the network entity 105-a may ensure that the measurement gap and the switching gap do not overlap and cause a collision at the UE 115-a.

As another option, the UE 115-a may prioritize the measurement gap over the switching period in the event that the UE 115-a is incapable of handling simultaneous channel quality measurement and transmission switching. For example, the UE 115-a may receive an uplink grant 210 that schedules the UE 115-a to transmit a PUSCH transmission 215-a using a first frequency band followed by a PUSCH transmission 215-b using a second frequency bands. Between the PUSCH transmission 215-a and the PUSCH transmission 215-b there may be a measurement gap. As opposed to performing switching (to switch from the first frequency band to the second frequency band) during the measurement gap, the UE 115-a may perform switching during the PUSCH transmission 215-a or the PUSCH transmission 215-b. In other words, a portion of the PUSCH transmission 215-a or the PUSCH transmission 215-b may be dropped in order to perform switching. Using the methods as described herein may allow the UE 115-a to avoid collisions between measurement gaps and switching gaps which may mitigate errors (e.g., errors in InterOperability Device Testing (IoDT) ) resulting from the collisions.

FIG. 3A and 3B shows an example of a switching scheme 300 (e.g., a switching scheme 300-a and a switching scheme 300-b) that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. In some examples, the switching schemes 300 may implement aspects of a wireless communications system 100 and a wireless communications system 200. For example, the switching schemes 300 may be implemented by a network entity 105 or a UE 115 as described with reference to FIGs. 1 and 2.

As described with reference to FIG. 2, a network entity may schedule a UE to transmit consecutive uplink messages using different frequency bands in such a way as to avoid collisions between measurement gaps 320 and switching gaps 310. In the example of FIG. 3A, the UE may receive an UL grant scheduling the UE to transmit a first PUSCH transmission 315-a during a first set of symbols (e.g., from T0 to T1) using a band 305-b and a second PUSCH transmission 315-a during a second set of symbols using a band 305-a (e.g., from T4 to T5) .

As shown in FIG. 3A, between the first set of symbols and the second set of symbols, the UE may perform channel quality measurements and as such, there may be a measurement gap 320-a on the serving band or band 305-c (e.g., from T3 to T4) . Additionally, between the first set of symbols and the second set of symbols and prior to the measurement gap 320-a, the UE may perform RF tuning to switch from the band 305-b to the band 305-a and as such, there may be a switching gap 310-a on the band 305-b (e.g., from T1 to T2) .

To ensure that the measurement gap 320-a does not overlap with the switching gap 310-a and to provide the UE sufficient time to prepare the measurement gap 320-a, the network entity may schedule a gap between the switching gap and the measurement gap. The gap may span from T2 to T3 and a value of the gap may be equal to X. In some examples, the value of X may be pre-configured at the network entity. In another example, the UE may determine the value of X based on its capability and report the value of X to the network entity. The value of X may be expressed in microseconds or a quantity of symbols.

Thus, in FIG. 3A, upon receiving the UL grant, the UE may transmit the first PUSCH transmission 315-a using band 305-b from T0 to T1. From T1 to T2, the UE may perform RF tuning and switch from the band 305-b to the band 305-a. Further, the UE may prepare the measurement gap 320-a during the gap which spans T2 to T3 and perform channel quality measurements during the measurement gap 320-a from T3 to T4.Further, from T4 to T5, the UE may transmit the second PUSCH transmission 315-a using the band 305-a.

In the example of FIG. 3B, the UE may receive an UL grant scheduling the UE to transmit a first PUSCH transmission 315-b during a first set of symbols (e.g., from T0 to T1) using a band 305-e and a second PUSCH transmission 315-b during a second set of symbols using a band 305-d (e.g., from T4 to T5) .

As shown in FIG. 3B, between the first set of symbols and the second set of symbols, the UE may perform channel quality measurements and as such, there may be a measurement gap 320-b on the serving band or band 305-f (e.g., from T1 to T2) . Additionally, between the first set of symbols and the second set of symbols and after the measurement gap 320-b, the UE may perform RF tuning to switch from the band 305-e to the band 305-d and as such, there may be a switching gap 310-b on the band 305-d (e.g., from T3 to T4) .

To ensure that the measurement gap 320-b does not overlap with the switching gap 310-b and to provide the UE sufficient time to prepare for the switching gap 310-b, the network entity may schedule a gap between the switching gap 310-b and the measurement gap 320-b. The gap may span from T2 to T3 and a value of the gap may be equal to Y. In some examples, the value of Y may be pre-configured at the network entity. In another example, the UE may determine the value of Y based on its capability and report the value of Y to the network entity. The value of Y may be expressed in microseconds or a quantity of symbols.

Thus, in FIG. 3B, upon receiving the UL grant, the UE may transmit the first PUSCH transmission 315-b using band 305-e from T0 to T1. From T1 to T2, the UE may perform channel quality measurements during the measurement gap 320-b. Further, the UE may prepare the switching gap 310-b during the gap which spans T2 to T3 and from T3 to T4, the UE may perform RF tuning to switch from the band 305-e to the band 305-d. Further, from T4 to T5, the UE may transmit the second PUSCH transmission 315-b using the band 305-d.

FIGs. 4A and 4B shows an example of a switching scheme 400 (e.g., the switching scheme 400-a and the switching scheme 400-b) that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. In some examples, the switching schemes 400 may implement aspects of a wireless communications system 100 and a wireless communications system 200. For example, the switching schemes 400 may be implemented by a network entity 105 or a UE 115 as described with reference to FIGs. 1 and 2.

As described with reference to FIG. 2, the UE may drop at least a portion of an uplink message to perform RF tuning such that a switching gap 410 used by the UE to perform the RF tuning does not overlap with a measurement gap 420 used by the UE to perform channel quality measurements. In the example of FIG. 4A, the UE may receive an UL grant from a network entity scheduling the UE to transmit a first PUSCH transmission 415-a during a first set of symbols (e.g., from T0 to T1) using a band 405-b and a second PUSCH transmission 415-a during a second set of symbols (e.g., from T2 to T4) using the band 405-a.

As shown in FIG. 4A, between the first set of symbols and the second set of symbols, the UE may perform channel quality measurements and as such, there may be a measurement gap 420-a on the serving band or band 405-c (e.g., from T1 to T2) . To switch from the band 405-b to the band 405-a, the UE may perform RF tuning. However, as shown in FIG. 4A, there may not be a sufficient gap of time between the first set of symbols and the measurement gap 420-a or the second set of symbols and the measurement gap 420-a for the UE to perform the RF tuning. As such, the UE may prioritize the measurement gap 420-a and perform the RF tuning during at least a portion of the second PUSCH transmission 415-a. That is, a subset of the second set of symbols (e.g., from T2 to T3) may include the switching gap 410-a.

Thus, in the example of FIG. 4A, upon receiving the UL grant, the UE may transmit the first PUSCH transmission 415-a using band 405-b from T0 to T1. From T1 to T2, the UE may perform channel quality measurements during the measurement gap 420-a. Further, the UE may perform RF tuning and switch from the band 405-b to the band 405-a from T2 to T3 and during a first portion of the second PUSCH transmission 415-a. From T3 to T4, the UE may perform a second portion of the second PUSCH transmission 415-a using the band 405-a. The first portion of the PUSCH transmission may be dropped such that the UE may perform switching from T2 to T3.

In the example of FIG. 4B, the UE may receive an UL grant from a network entity scheduling the UE to transmit a first PUSCH transmission 415-b during a first set of symbols (e.g., from T0 to T2) using a band 405-e and a second PUSCH transmission 415-b during a second set of symbols (e.g., from T3 to T4) using the band 405-d.

As shown in FIG. 4B, between the first set of symbols and the second set of symbols, the UE may perform channel quality measurements and as such, there may be a measurement gap 420-b on the serving band or band 405-f (e.g., from T2 to T3) . To switch from the band 405-e to the band 405-d, the UE may perform RF tuning. However, as shown in FIG. 4B, there may not be a sufficient gap of time between the first set of symbols and the measurement gap 420-b or the second set of symbols and the measurement gap 420-b for the UE to perform the RF tuning. As such, the UE may prioritize the measurement gap 420-b and perform the RF tuning during at least a portion of the first PUSCH transmission 415-b. That is, a subset of the second set of symbols (e.g., from T1 to T2) may include the switching gap 410-b.

Thus, in the example of FIG. 4B, upon receiving the UL grant, the UE may transmit a first portion of the first PUSCH transmission 415-b using band 405-e from T0 to T1. From T1 to T2 and during a second portion of the first PUSCH transmission 415-b, the UE may perform RF tuning and switch from the band 405-e to the band 405-d. The second portion of the first PUSCH transmission 415-b may be dropped such that the UE may perform switching from T1 to T2. Further, from T2 to T3, the UE may perform channel quality measurements during the measurement gap 420-b. Lastly, from T3 to T4, the UE may transmit the second PUSCH transmission 415-b using the band 405-d.

FIG. 5 shows an example of a switching scheme 500 that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. In some examples, the switching scheme 500 may implement aspects of a wireless communications system 100 and a wireless communications system 200. For example, the switching scheme 500 may be implemented by a network entity 105 or a UE 115 as described with reference to FIGs. 1 and 2.

As described with reference to FIG. 2, in some examples, a UE may be capable of performing RF tuning while performing channel quality measurements. In the example of FIG. 5, the UE may receive an uplink grant from a network entity scheduling the UE to transmit a first PUSCH transmission 515 using a first set of symbols (e.g., T0 to T1) and a second PUSCH transmission 515 using a second set of symbols (e.g., T3 to T4) .

As shown in FIG. 5, between the first set of symbols and the second set of symbols, the UE may perform channel quality measurement and as such, there may be a measurement gap 520 in the serving band or a band 505-a (e.g., from T1 to T3) . To switch from the band 505-b to the band 505-a, the UE may perform RF tuning. However, as shown in FIG. 5, there may not be a sufficient gap of time between the first set of symbols and the measurement gap 520 or the second set of symbols and the measurement gap 520 for the UE to perform the RF tuning. As such, the UE may and perform the RF tuning during at least a portion of the measurement gap 520. That is, a subset of symbols allocated for the measurement gap 520 may include the switching gap 510.

Thus, in the example of FIG. 5, upon receiving the UL grant, the UE may transmit the first PUSCH transmission 515 using band 505-b from T0 to T1. From T1 to T3, the UE may perform channel quality measurements during the measurement gap 520. Further, during a portion of the measurement gap 520 and from T2 to T3, the UE may perform RF tuning and switch from the band 505-b to the band 505-a. Lastly, from T3 to T4, the UE may transmit the second PUSCH transmission 515 using the band 505-a.

FIG. 6 shows an example of a process flow 600 that supports collision rules for measurement gaps in accordance with one or more aspects of the present disclosure. In some examples, the process flow 600 may implement, or be implemented by, aspects of a wireless communications system 100 and a wireless communications system 200. For example, the process flow 600 may be performed by a UE 115-b and a network entity 105-b which may be example of a UE 115 and a network entity 105 as described with reference to FIGs. 1 and 2, respectively. Alternative examples of the following may be implemented, where some steps are performed in a different order then described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

At 605, the UE 115-b may transmit first signaling indicating a capability of the UE 115-b to perform channel quality measurements on one or more reception frequency bands during a switching period that defines a duration for the UE to switch from transmitting using a first transmission band to transmitting using a second transmission frequency band.

At 610, the UE 115-b, based on the first signaling indicating the capability, may receive an uplink grant from the network entity 105-b scheduling the UE 115-b to transmit first uplink signaling using the first transmission frequency band and transmit second uplink signaling using the second transmission frequency band. In some examples, the uplink grant may indicate a first set of symbols allocated for transmission of the first uplink signaling and a second set of symbols allocated for transmission of the second uplink signaling. In some examples, the first set of symbols may be associated with an earlier time slot than a time slot associated with the second set of symbols.

In one example, the capability may indicate an inability of the UE 115-b to perform channel quality measurements during the switching period. In such case, the network entity 105-b may schedule the UE 115-b in such a way as to ensure that the switching period and a measurement gap for performing the channel quality measurement do not overlap. As one example of this, at 615, the UE 115-b may transmit the first uplink signaling using the first set of symbols and then, at 620, the UE 115-b may perform channel quality measurements a first gap period after the switching period which may occur after a last symbol of the first set of symbols. Further, at 625, the UE 115-b may transmit the second uplink signaling using the second set of symbols.

As another option, at 615, the UE 115-b may transmit the first uplink signaling using the first set of symbols and then, at 620, the UE 115-b may perform channel quality measurements. Further, at 625, the UE 115-b may transmit the second uplink message after the switching period that occurs a second gap period after performing the channel quality measurements. In some examples, prior to transmitting the first signaling indicating the capability, the UE 115-b may transmit second signaling to the network entity 105-b indicating one or more gap periods that may include one or both of the first gap period or the second gap period. In some examples, the one or more gap periods may be based on a capability of the UE 115-b.

Alternatively, if the UE 115-b does not have the ability to perform channel quality measurements during the switching period, the UE 115-b may prioritize the measurement gap for performing channel quality measurement over the switching period. As one example, at 615, the UE 115-b may transmit the first uplink signaling using the first set of symbols and then, at 620, the UE 115-b may perform channel quality measurements. After performing the channel quality measurements, the UE 115-b may switch from the first transmission frequency band to the second transmission frequency band during a switching period that spans a first subset of the second set of symbols and at 625, the UE 115-b may transmit the second uplink signaling using a second subset of second set of symbols.

As another example, at 615, the UE 115-b may transmit the first uplink signaling during a first subset of the first set of symbols and switch from the first transmission frequency band to the second transmission frequency band during a switching period that spans a second subset of the first set of symbols. After switching and at 620, the UE 115-b may perform channel quality measurements and at 625, the UE 115-b may transmit the second uplink signaling using the second set of symbols. That is, the UE 115-b may drop at least a portion of the first uplink signaling or the second uplink signaling to perform switching during the switching period. In some examples, the UE 115-b will refrain from transmitting one or more of the first uplink signaling or the second uplink signaling completely in order to perform switching during the switching period.

Alternatively, the capability may indicate an ability of the UE 115-b to perform channel quality measurements during the switching period. In such case, at 615, the UE 115-b may transmit first uplink signaling using the first set of symbols and then, at 620, the UE 115-b may perform channel quality measurement during the measurement gap. Further, during at least a portion of the measurement gap, the UE 115-b may switch from the first transmission frequency band to the second transmission frequency band during the switching period. Further, at 625, the UE 115-b may transmit the second uplink signaling using the second set of symbols. Using such methods may allow the UE 115-b to handle potential conflicts between measurement gaps and switching periods which may mitigate error at the UE 115-b.

The various illustrative blocks and components described in connection with the disclosure herein may be implemented or performed using a general-purpose processor, a DSP, an ASIC, a CPU, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.

The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.

Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) , or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium.

As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”

As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”

The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure) , ascertaining and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.

In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label, or other subsequent reference label.

The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration, ” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
