Cross-reference to related applications

The present application claims priority to the Chinese Patent Office, filed on Jan. 10, 2017, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method for configuring an uplink transmission start location, an access network entity, and a UE (User Equipment).

Background technique

With the continuous growth of mobile data traffic, the frequency band resources of mobile communication systems are becoming more and more tense. Only the use of licensed frequency band resources for network deployment and service transmission may not meet the requirements of mobile data traffic. Therefore, it may be considered to deploy on licensed frequency band resources. Transport mobile data services to improve frequency band resource utilization and improve user experience.

The traditional LTE (Long Term Evolution) uses centralized scheduling centered on the access network entity when working in the unlicensed band. For the uplink transmission of the UE, the scheduling request needs to be initiated first, and then the access network entity is awaited. Upstream scheduling can send data. Before the UE and the access network entity send a signal, they need to perform LBT (Listen Before Talk), which easily leads to degradation of uplink transmission performance.

Based on the above-mentioned conventional scheduling-based uplink transmission, it is further proposed to adopt a Grant-less UpLink (GUL) based on UE autonomous scheduling, which allows the UE to initiate uplink transmission autonomously. However, for a UE adopting GUL, how to determine the starting position of the uplink transmission is a problem to be solved because the LBT conditions of different UEs are different.

Summary of the invention

detailed description

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the scope of the invention are within the scope of the disclosure.

In the embodiment of the present disclosure, the mobile communication system refers to an operator providing communication services for the UE by deploying a radio access network device (such as a base station) and a core network device (such as a Home Location Register, HLR). system.

As shown in FIG. 1, FIG. 1 shows a basic architecture diagram of a mobile communication network. Mobile communications have experienced first, second, third and fourth generations. The first generation of mobile communication refers to the original analog, voice-only cellular phone standard, mainly using analog technology and Frequency Division Multiple Access (FDMA) access methods. The second generation of mobile communications introduced digital technology to improve network capacity, improve voice quality and confidentiality, with "Global System for Mobile Communication (GSM)" and "Code Division Multiple Access" , CDMA IS-95)" is representative. The third generation mobile communication mainly refers to three technologies of CDMA2000, WCDMA and TD-SCDMA. All three technologies use code division multiple access as the access technology. The standards of the fourth generation mobile communication system are relatively uniform internationally, and are the Long Term Evolution/Long Term Evolution-Advanced (LTE/LTE-A) developed by the International Organization for Standardization (3GPP). The downlink is based on orthogonal frequency division multiple access. Orthogonal Frequency Division Multiple Access (OFDMA), uplink based on Single Carrier-Frequency Division Multiple Access (SC-FDMA) access mode, based on flexible bandwidth and adaptive modulation and coding A high-speed transmission with a downlink peak rate of 1 Gbps and an uplink peak rate of 500 Mbps is achieved.

Based on the LTE R13 LAA downlink transmission method, an uplink transmission method is newly defined, for example, MulteFire, which is an LTE technology that supports the UE to work independently in an unlicensed band, that is, stand-alone LTE-U. In the transmission of the unlicensed band, the channel access specification of the band is to be observed. For example, the unlicensed band of 5 GHz needs to be listened to by LBT (Listen Before Talk), that is, it is required to detect that the channel is idle before sending. . In the traditional LTE, the centralized scheduling based on the access network entity is adopted. For the uplink transmission of the UE, the scheduling request needs to be initiated first, and then the uplink scheduling of the access network entity is waited for the uplink transmission. In this way, both the UE and the access network entity need to perform LBT before each signal is sent. Therefore, the traditional uplink transmission based on the access network entity scheduling, especially the Wi-Fi device shared channel based on distributed scheduling, In the transmission of unlicensed frequency bands, it is easy to cause performance degradation such as uplink throughput and delay, and reduce the success rate of LBT.

For the above-mentioned traditional uplink transmission mode based on centralized scheduling of the access network entity, MulteFire proposes to adopt uplink scheduling based on UE autonomous scheduling, that is, AUL (Autonomous UpLink) or GUL (Grant-less UpLink), which is unified in the embodiment of the present disclosure. Referred to as GUL, it allows the UE to initiate uplink transmission autonomously, reducing the delay and reducing the number of LBTs.

However, for a UE adopting GUL, the LBT conditions for different UEs are different, and how to implement user uplink multiplexing becomes a major challenge faced by GUL uplink transmission. If each UE of the GUL occupies the entire system broadband for uplink transmission, only the multiplexing mode such as TDM/CDM/SDM can be used. Especially for the TDM (Time Division Multiplexing) method, the delay is considered. The TxOP (Transmission Opportunity) of the UE is reduced, which in turn leads to an increase in the LBT/control overhead. In addition, if each UE of the GUL occupies part of the system bandwidth (interlace based, based on interleaving unit allocation), FDM (Frequency Division Multiplexing) mode can be adopted, but how multiple UEs with orthogonal resources can be in the same sub- The LBT succeeds and transmits on the frame, and how the UEs with non-orthogonal resources can avoid colliding in the same subframe has to be resolved.

Based on the above situation, the present disclosure provides a method for configuring an uplink transmission start position, which will be described in detail below in conjunction with specific embodiments.

It should be noted that, in the embodiment of the present disclosure, the user equipment (User Equipment, referred to as “UE”) may be referred to as a terminal, a mobile station (Mobile Station, abbreviated as “MS”), and a mobile terminal (Mobile). Terminal) and so on. For example, the UE can be a mobile phone (or cell phone), or other device capable of transmitting or receiving wireless signals, including a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, wireless local. A circuit (WLL) station, a CPE (Customer Premise Equipment) capable of converting a mobile signal into a WiFi signal, a mobile intelligent hotspot, a smart home appliance, or other device capable of spontaneously communicating with a mobile communication network without human operation Wait.

The access network entity may be a base station. It may be understood that the form of the foregoing base station is not limited, and may be a Macro Base Station, a Pico Base Station, or a Node B (a name of a 3G mobile base station). Enhanced base station (ENB), home enhanced base station (Femto eNB or Home eNode B or Home eNB or HNEB), relay station, access point, RRU (Remote Radio Unit), RRH (Remote Radio Head, RF remote head) and so on.

First embodiment

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for configuring an uplink transmission start location according to an embodiment of the present disclosure, where an execution entity of the method may be an access network entity, as shown in FIG. 2, where the method includes The following steps:

Step 201: The access network entity configures an uplink transmission GUL parameter based on UE autonomous scheduling for the UE, where the GUL parameter includes at least location information of one or more subframes supporting the GUL, and one or more of each subframe. Uplink transmission start position information.

In this step, the access network entity configures a GUL parameter for the UE, where the GUL parameter includes at least location information of a subframe supporting GUL and one or more uplink transmission start location information in each subframe. The subframe supporting the GUL may be one subframe or multiple subframes, and each subframe supporting the GUL may include an uplink transmission start position, and may also include multiple uplink transmission start positions. The access network entity may configure the GUL parameter for the UE by using high layer signaling (for example, radio resource control RRC signaling, etc.), or may configure the GUL parameter for the UE by using physical layer control signaling.

In an embodiment of the present disclosure, the access network entity may configure different uplink transmission start positions for the UE in different GUL subframes. The UE may determine an uplink transmission start location according to the current subframe. For example, the UE may determine an uplink transmission start according to one or more of a frame number, a subframe number, a UE identifier, and a cell radio network temporary identifier. position.

In the embodiment of the present disclosure, the GUL parameter may further include a GUL time-frequency resource and a transmission parameter (for example, a parameter in an uplink resource scheduling signaling UL grant). The GUL time-frequency resources include GUL frequency resources and/or codeword resources.

The access network entity may configure different GUL subframes for different UEs to implement TDM at the subframe level, or configure the same GUL subframe for multiple different UEs, and perform TDM or FDM through the LBT. When the access network entity configures the same GUL subframe for the multiple different UEs, the access network entity may configure different uplink transmissions for the multiple different UEs in the same GUL subframe. a starting position, where the same uplink transmission start position may be configured in the same GUL subframe for the multiple different UEs, where the access network entity is in the same GUL sub When the same uplink transmission start position is configured in the frame, the access network entity further configures mutually orthogonal frequency resources and/or orthogonal to each other in the same GUL subframe for the multiple different UEs. Codeword resource.

In some embodiments of the present disclosure, the access network entity may also configure different uplink transmission start positions in the same GUL subframe for multiple groups of UEs, and the uplink transmission start positions of the same group of UEs are the same. A plurality of UEs in a group of UEs are orthogonal to each other and/or codeword resources are orthogonal to each other in the same GUL subframe, so that multiplexing of multiple UEs in the same GUL subframe is implemented. The same UE may be configured with multiple transmission start positions and corresponding frequency and/or codeword resources (for example, the same UE may belong to multiple different groups at the same time), when the UE is at a certain transmission start position. The time-frequency resource and/or codeword resource corresponding to the transmission start position is used for transmission.

The access network entity may configure a plurality of consecutive GUL subframes for the UE. For example, after the Cat-4LBT of the UE is successful, the access network entity is configured with multiple consecutive GUL sub-subjects under the requirement of satisfying the maximum channel occupation duration corresponding to the channel access priority. The UE may perform GUL uplink transmission on the plurality of consecutive GUL subframes. In the embodiment of the present disclosure, in order to prevent multiple UEs from continuously colliding on the multiple consecutive GUL subframes, if the UE does not occupy the entire system bandwidth, the UE performs UE-specific on multiple occupied subframes. (mobile-specific) frequency hopping and/or codeword change, the frequency hopping and/or codeword change pattern being based at least on the UE's UE ID (C-RNTI generation) and/or the cell ID to which the UE belongs determine. In addition, a frequency modulation and/or codeword change pattern, such as a group-specific hopping pattern, may also be generated according to the group ID to which the UE belongs.

The access network entity may configure the same frequency resource and/or codeword resource for the UE in different GUL subframes, or configure different frequency resources and/or different frequency resources for the UE in different GUL subframes. Or codeword resources. The access network entity may allocate different preamble sequences to different UEs, and the different preamble sequences may indicate different uplink transmission start positions. Correspondingly, the UE may transmit a preamble sequence after the uplink transmission start position when performing GUL uplink transmission, and the access network entity may blindly check a preamble sequence sent by the UE on the current subframe, and then according to the The preamble sequence determines related information such as an uplink transmission arrival and a starting position of the UE, thereby achieving correct reception of data. Step 202: The access network entity provides the GUL parameter to the UE.

In this step, the access network entity provides the GUL parameter to the UE after configuring the GUL parameter for the UE. It can be understood that the access network entity provides the GUL to the UE. The parameter may be that the access network entity sends the GUL parameter to the UE, or the UE may actively obtain the GUL parameter from the access network entity, which is not specifically limited in the disclosure. The access network entity may send the GUL parameter to the UE by using high layer signaling (eg, radio resource control RRC signaling, etc.), or may send the GUL parameter to the UE by using physical layer control signaling.

Optionally, the access network entity configures, by the UE, different uplink transmission start positions in different GUL subframes.

In this embodiment, the access network entity configures different uplink transmission start positions in the different GUL subframes of the UE, and the UE needs to perform GUL uplink transmission in the Cat-4LBT (ie, the 3GPP standard). The competition window-based channel contention access mode specified in the method determines the uplink transmission start position of the current subframe after successful, and then starts the data transmission at the uplink transmission start position in the current subframe. Specifically, the uplink transmission start position of the UE in different GUL subframes may be changed according to one or more of the following: frame number, subframe number, UE identification code (UE ID), and cell radio network temporary identifier C. -RNTI. That is to say, in this embodiment, the UE may determine an uplink transmission start position in the current subframe according to one or more of the foregoing, and then transmit data after the uplink transmission start position.

Optionally, the uplink transmission start position of the UE in different GUL subframes is adjusted according to at least one of a frame number, a subframe number, a UE identifier, and a cell radio network temporary identifier.

In this embodiment, the start position of the PUSCH (Physical Uplink Shared Channel) in the GUL subframe includes a first symbol (for example, symbol 0) and a second symbol (for example, symbol 1), and uplink transmission starts from The start position can be implemented by sending other signals before the PUSCH. For example, by transmitting a reservation signal and/or a preamble signal, the UE may start GUL transmission before the first symbol or the second symbol after the success of the Cat-4 LBT. The uplink transmission start position of the UE in different GUL subframes may be different. For example, it is assumed that the GUL subframe of the current cell includes multiple uplink transmission start positions (for example, OS#0, OS#1-25us). , OS#1), the GUL start position configured by the access network entity for the UE is that the PUSCH is transmitted from the second symbol, and the configured uplink transmission start position is OS#1-25us. Then, the next GUL subframe that needs to be successfully transmitted by the cat-4LBT needs to determine the current uplink transmission start position according to the current GUL subframe number and/or SFN (system frame number) number. The PUSCH is started from the second symbol, OS#1, and OS#1-25us and OS#1 can transmit the reserved signal.

Optionally, the GUL parameter further includes a GUL frequency resource and/or a codeword resource.

In this embodiment, the GUL parameter may further include a GUL frequency resource and/or a codeword resource to implement multiplexing of multiple UEs in the same GUL subframe. For example, when the access network entity configures the same uplink transmission start position in the same GUL subframe for multiple UEs, the access network entity further is that the multiple UEs are in the same GUL. The mutually orthogonal frequency resources and/or mutually orthogonal codeword resources are arranged in the subframe, so that resource multiplexing of multiple UEs in the same GUL subframe is implemented.

Optionally, the access network entity configures, by the multiple UEs, the same uplink transmission start location in the same GUL subframe, and the multiple UEs are orthogonal to each other in the same GUL subframe. And/or codeword resources are orthogonal to each other.

In this embodiment, the access network entity configures the same uplink transmission start position in the same GUL subframe for multiple UEs in a group of UEs, and GULs orthogonal to each other in the same GUL subframe. Frequency resources and/or codeword resources, thereby enabling multiplexing of multiple UEs within the same GUL subframe.

Optionally, the access network entity configures different uplink transmission start positions in the same GUL subframe for multiple groups of UEs, and multiple UEs in each group of UEs have frequency resources in the same GUL subframe. The mutually orthogonal and/or codeword resources are orthogonal to each other.

In this embodiment, the access network entity configures different uplink start positions in the same GUL subframe for different groups of UEs, where each group of UEs includes one or more UEs, and each group Multiple UEs in the UE are orthogonal to each other in the same GUL subframe and/or the codeword resources are orthogonal to each other. Specifically, the access network entity can allocate more on the same time-frequency resource because it cannot be determined whether multiple UEs can have uplink transmission requirements at the same time, and the uplink LBT time and result of each UE are relatively independent. UEs to ensure resource utilization and reduce access delay. That is, the access network entity allocates the same time-frequency resource to the multiple UEs. In addition, in order to prevent collisions between UEs with the same resources and LBT success, the access network entity configures the same GUL for UEs with the same resource allocation (ie, UEs with the same GUL frequency resource and/or codeword resource). Different upstream transmission start positions within the subframe. In this way, the access network entity can implement multiplexing of the same group of UEs by configuring different uplink transmission start positions for different groups of UEs, and effectively avoid conflicts between different groups of UEs, and can also sequentially transmit sequence guarantees by rotation. Fairness. In this way, different uplink transmission start positions can be configured for the UE according to resources such as the time-frequency code of the UE, and the channel competition fairness between users can be ensured by periodically changing the uplink transmission start position.

For example, in the nth GUL subframe, the uplink transmission start position is configured as OS#1-25us for the first group of UEs, and the uplink transmission start position is configured as OS#1-16us for the second group of UEs. The UE configures the uplink transmission start position to be OS#1. By analogy, the access network entity can configure the uplink transmission starting position for different groups of UEs as follows:

In SF#n:

Group#1:OS#1-25us;group#2:OS#1-16us;group#3:OS#1

In SF#n+1:

Group#1:OS#1-16us;group#2:0S#;group#3:OS#1-25us

In SF#n+2: and so on...

Optionally, the access network entity configures different frequency resources and/or codeword resources for the UE in different GUL subframes.

In this embodiment, the access network entity configures different GUL frequency resources and/or codeword resources in the different GUL subframes of the UE, and can effectively avoid collision with uplink transmission data of other UEs. When the access network entity configures multiple consecutive GUL subframes for the UE, the access network entity configures different frequency resources and/or codeword resources for the UE in different subframes, such that It can effectively avoid multiple subframes from continuously colliding.

Optionally, the method further includes:

The access network entity acquires a preamble signal and/or a reserved signal that is transmitted by the UE after the uplink transmission start position.

In this embodiment, after acquiring the GUL parameter and determining an uplink transmission start position according to the GUL parameter, the UE transmits a preamble signal and/or a reserved signal after the uplink transmission start position, where The access network entity receives a preamble signal and/or a reserved signal transmitted by the UE after the uplink transmission start position. The preamble signal may include a preamble sequence configured for the UE as the access network entity.

In some embodiments of the present disclosure, the access network entity configures different preamble sequences for different UEs, wherein different preamble sequences indicate different UEs or UE groups. Correspondingly, after receiving the preamble sequence transmitted by the UE after the uplink transmission start position, the access network entity may further determine, according to the preamble sequence, an uplink transmission arrival and a transmission start location of the UE. So that data can be correctly received according to the determined uplink transmission start position.

Optionally, the access network entity allocates different preamble sequences to different UEs, where different preamble sequences indicate uplink transmissions of different UEs.

In this embodiment, the access network entity allocates different preamble sequences to different UEs, and the different preamble sequences indicate uplink transmissions of different UEs, and the UE may start in the uplink transmission when performing uplink data transmission. The preamble sequence is transmitted after the start position.

Optionally, the access network entity allocates different preamble sequences to the same UE, and is used to indicate different uplink transmission information.

In this embodiment, the access network entity allocates different preamble sequences to the same UE, where different preamble sequences indicate different uplink data transmission start positions, and the UE may indicate access by sending different preamble sequences. The starting position of the current uplink transmission of the network entity. In addition, different preamble sequences may also include corresponding start positions of different uplink data transmissions, resource information of different uplink control channels, and the like.

For example, when the signal transmitted before the PUSCH includes a preamble signal, the access network entity may indicate related information of the subsequent GUL transmission by using a preamble signal, such as a start bit position of the PUSCH, and a PUCCH/ePUCCH/sPUCCH/xPUCCH A video codeword resource or the like, wherein the preamble signal may be generated by a ZC sequence (root sequence), such as a DMRS (Demodulation Reference Signal) sequence. The access network entity may implement resource orthogonality by allocating different preamble sequences for different UEs or different groups of UEs.

Optionally, the method further includes:

The access network entity blindly detects a preamble sequence sent by the UE on the current subframe;

The access network entity determines an uplink transmission arrival location and a starting location of the UE according to the preamble sequence.

In this embodiment, the access network entity blindly detects the preamble sequence sent by the UE in the current subframe, and then determines the uplink transmission arrival location and the starting location of the UE according to the preamble sequence. Specifically, the access network entity may identify a UE or a group of UEs from which a GUL (User Class Identifier) signal arrives or is obtained by blindly detecting a preamble sequence sent by a possible GUL UE in the current subframe. Further, the access network entity may determine corresponding UCI and PUSCH information according to the preamble sequence, such as a time-frequency codeword resource of UCI, a starting position of a PUSCH, and the like.

It should be noted that, in some embodiments of the present disclosure, the UE may also determine, by using a preamble sequence of other UEs in the current GUL subframe, whether the uplink transmission of the UE and other UEs collides, and stop the PUSCH when a collision occurs. transmission. Specifically, the UE may obtain the preamble sequence used by other UEs in the current GUL subframe by acquiring the information provided by the access network entity, and may also learn the preamble sequence used by other UEs in the current GUL subframe by using a blind detection manner. . When the UE needs to transmit its own preamble sequence and/or LBT, the UE determines whether to collide with other UEs according to a preamble sequence sent by other UEs on the current GUL subframe, and the UE determines that it occurs with other UEs. In the case of a collision, the subsequent PUSCH transmission is stopped, and the continuous collision with other UEs is effectively avoided.

In this embodiment, the access network entity configures an uplink transmission GUL parameter based on UE autonomous scheduling for the UE, where the GUL parameter includes at least location information of one or more subframes supporting the GUL, and one in each subframe. Or a plurality of uplink transmission start location information; the access network entity providing the GUL parameter to the UE. In this way, the uplink transmission start position of the UE can be configured before the UE performs the GUL uplink transmission, and the fairness of the channel competition of different UEs is ensured, and the UE is reused in the subframe to improve the channel utilization.
