For ease of understanding, some contents involved in the embodiments of the present application are described below:

In addition to user data, the data transmitted within 5G and 6G mobile networks also include a large amount of mobile network internal data, such as positioning data, perception data, AI models, AI model training data, etc.

Among them, perception data involves communication perception fusion technology, which, on the one hand, uses the communication system to improve perception accuracy, improve perception timeliness, and realize seamless ubiquitous perception services; on the other hand, based on the perception, identification and prediction of the wireless communication channel environment, it further improves the performance of the wireless communication system and helps build a smart network. Regarding perception-assisted communication, potential use cases include reconstructing the environment between the base station and the terminal (User Equipment, UE) based on perception, and assisting in channel estimation or non-line-of-sight (NLOS) signal utilization based on the reconstructed information. Potential use cases for perception-assisted communication currently discussed in the industry include perception-assisted beam management, perception-assisted channel estimation enhancement, perception-assisted positioning, etc. In the case of perception-assisted communication, considering that the time slot and subframe interval of communication do not exceed the millisecond level, perception-assisted communication usually has higher real-time requirements, and requires that the overhead introduced by perception-assisted communication be as small as possible.

In the embodiments of the present application, a corresponding technical solution is designed for data transmitted within a mobile network, especially for data within a mobile network such as perception-assisted communication, which has high requirements for real-time data transmission and low overhead.

Traditional communication systems use source coding and channel coding to transmit user-side data (such as images/videos/text/voices), and divide the source and channel coding into two modules for independent design. Separate source-channel coding (SSCC) has the characteristics of simple design and modularity, but in actual communication systems, the system's tolerable delay, complexity, and code length are limited, making it difficult to meet the assumption of unlimited code length in Shannon's separation theorem. In addition, the separation theorem is applicable to point-to-point communication systems and situations where the source and channel distribution are known, but the separation theorem is not applicable in scenarios such as multi-user communication and mobile communication with time-varying channels. Research on source channel joint coding describes that for specific purposes, the source channel joint coding technology can effectively reduce the amount of transmitted data under the same service quality requirements, for example, under the same Peak Signal-to-Noise Ratio (PSNR), the source channel joint coding technology has gains in low Signal-to-Noise Ratio (SNR) conditions or when you want to reduce transmission overhead.

The existing protocol standards have not yet adopted the source-channel joint coding technology. The embodiment of the present application designs a corresponding technical solution for the process of executing the source-channel joint coding technology for data transmitted over the mobile network. The embodiment of the present application is illustrated by taking the internal data of the mobile network as an example. It can be understood that this technical solution is applicable to both user data of existing applications and data within the mobile network. Unlike the user data carried by the user plane of the 5G network, the data within the mobile network is mainly used by UE, wireless access network nodes, and core network nodes for optimizing the network itself or opening up network capabilities to provide services to the outside of the network.

The following, in conjunction with the accompanying drawings, describes in detail the coding configuration method, apparatus, terminal, device and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

Referring to FIG. 2 , FIG. 2 is a flowchart of a coding configuration method provided in an embodiment of the present application, which is used in a terminal, as shown in FIG. 1 , and the method includes the following steps:

Step 201, the terminal receives a first message sent by a network side device; wherein the first message is used to indicate at least one of the following: whether the target data uses source-channel joint coding; and a first trigger condition for whether the target data uses source-channel joint coding.

In the embodiment of the present application, the network side device may be a wireless access network node, and may also be described as a first node. The network side device sends a first message to the UE, and the first message is used to indicate whether the target data uses source channel joint coding and at least one of the triggering conditions of the source channel joint coding. The target data may be internal data of the mobile network, and may also be applicable to user data of existing applications.

Optionally, the target data includes at least one of the following: positioning data, perception data, artificial intelligence AI model and AI model training data.

Optionally, the embodiments of the present application are applicable to data within a mobile network, especially data with characteristics such as large data volume and high real-time requirements, that is, optionally, the target data includes data within a mobile network. Perceptual assisted communication usually has higher real-time requirements, and requires that the overhead introduced by perceptual assisted communication be as small as possible. The embodiments of the present application are applicable to a perceptual data transmission method for perceptual assisted communication, and the perceptual data transmission method described above can support source-channel joint coding based on the indication of the first message. The method in the embodiments of the present application is also applicable to other data within a mobile network with characteristics such as large data volume and high real-time requirements, such as AI models, AI model training data, etc.

The mobile network internal data may refer to data that can be parsed by a UE, a wireless access network node, or a core network node in the 3GPP standard. The mobile network internal data includes at least one of the following:

1) Send and receive data that terminates at any two of the terminals, wireless access network equipment, and core network equipment;

It can also be described as a peer-to-peer protocol for sending and receiving data located at the UE, radio access network or core network.

For example, the data of the peer protocol layers of the Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP) are respectively located in the UE and the location management function (LMF) of the core network; another example is the data of the peer protocol layers of the Radio Resource Control (Radio Resource Control, RRC) are respectively located in the UE and the radio access network equipment (eNB/gNB, base station); another example is the data plane protocol layers are respectively located in the UE and the radio access network equipment or in the UE and the core network equipment.

2) Send or receive data that ends at any one of the terminals, wireless access network equipment or core network equipment.

It can also be described as data sent or received with one end located at the UE, radio access network or core network. For example, an AI model generated by an application server or application function outside the mobile network is sent to the UE, radio access network equipment or core network equipment, and the corresponding equipment needs to deploy and use the AI model.

The terminal (UE) involved in the above-mentioned mobile network content data refers to the protocol functions of the user equipment (User equipment) defined by the 3GPP protocol, excluding application functions.

For example, the mobile network internal data may include at least one of the following: perception data, positioning data, AI model and AI model training data.

The embodiments of the present application are applicable to 5G, 6G and future communication systems.

In the embodiment of the present application, the perception data includes at least one of a perception measurement report, a perception measurement result validity indication, and perception auxiliary data. The perception measurement report is mainly a measurement result obtained after measuring the perception measurement quantity, and the perception auxiliary data includes an environment map, target area information, etc.

Exemplarily, the perception measurement quantities can be divided into the following four categories (this example focuses on explaining the measurement quantities, and the four categories are only for illustration, and can also be divided into three categories or unclassified, etc.). According to the relationship between the perception measurement quantities and the perception services, the third and fourth level measurement quantities below are also generally referred to as perception results, and the second level and/or first level measurement quantities are referred to as perception measurement data:

a) First-level measurement quantity (received signal/original channel information), including: received signal/channel response complex result, amplitude/phase, I-channel/Q-channel and its operation results (operations include addition, subtraction, multiplication and division, matrix addition, subtraction and multiplication, matrix transposition, trigonometric relationship operation, square root operation and power operation, as well as threshold detection results, maximum/minimum value extraction results, etc. of the above operation results; operations also include Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT)/Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform and digital filtering, as well as threshold detection results, maximum/minimum value extraction results, etc. of the above operation results);

b) Second-level measurement quantities (basic measurement quantities), including: time delay, Doppler, angle, signal strength, and their multi-dimensional combination representation;

c) Level 3 measurements (basic attributes/status), including: distance, speed, angle/direction, radar cross section (RCS), acceleration;

d) Level 4 measurement quantities (advanced attributes/states), including: spatial position, target presence, trajectory, movement, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, and composition.

Optionally, in an embodiment of the present application, the first message is used to indicate whether the target data uses source-channel joint coding. It can be indicated in an explicit manner, for example, using 1 bit to indicate whether or not to use source-channel joint coding, or it can be implicitly indicated by indicating the coding method (for example, a specific coding algorithm, coding algorithm ID, coding model or coding model ID).

Optionally, in an embodiment of the present application, the first message is used to indicate a first trigger condition for whether the target data uses source-channel joint coding. The network side device sends the first trigger condition to the UE, so that the UE determines whether to perform source-channel joint coding based on the trigger condition.

Optionally, the condition parameter of the first trigger condition includes at least one of the following:

Trigger parameters for source-channel joint coding;

Trigger threshold for source-channel joint coding;

A triggering event for source channel joint coding, wherein the triggering event is determined based on at least one of a triggering parameter for source channel joint coding and a triggering threshold for source channel joint coding.

In an embodiment of the present application, the first trigger condition can be obtained by combining at least one of a trigger parameter, a trigger threshold and a trigger event. In other words, the source channel joint coding trigger condition includes at least one of a source channel joint coding trigger parameter, a trigger event type and a corresponding threshold value.

The first trigger condition includes at least one of the following:

A first trigger sub-condition, wherein the first trigger sub-condition is used to enable source-channel joint coding;

The second trigger sub-condition is used to turn off source channel joint coding.

It is understandable that in the embodiment of the present application, the first trigger condition (at least one of the trigger parameter and the trigger event) has the following usage scenarios:

1) By default, the UE does not enable source channel joint coding. The UE determines whether to enable source channel joint coding for data transmission based on the trigger parameter and the corresponding trigger threshold and at least one of the trigger events;

2) By default, the UE turns on the source channel joint coding, and the UE determines whether to turn off the source channel joint coding based on the trigger parameter and the corresponding trigger threshold, and at least one of the trigger events;

3) The UE determines whether to turn on or off the source channel joint coding based entirely on the trigger threshold or trigger condition corresponding to the trigger parameter.

Exemplarily, as shown in Table 1, the trigger condition may include at least one of an opening condition (entry condition) and a closing condition (exit condition).

Optionally, the trigger parameter of the source-channel joint coding includes at least one of the following:

Channel quality indicators;

Data length before source-channel joint coding;

The data length after the source channel joint coding;

Compression ratio;

Transfer resource size;

The time length of the source-channel joint coding;

The time length of the joint decoding of the source and channel;

The sum of the time lengths of source-channel joint encoding and source-channel joint decoding.

In an embodiment of the present application, the above-mentioned channel quality indicators, for example, may be parameters such as signal to interference plus noise ratio (SINR), reference signal receiving quality (RSRQ), reference signal receiving power (RSRP), etc. If SINR is taken as an example, SINR refers to the signal to interference plus noise ratio of the uplink and/or downlink channels. Source-channel joint coding is usually more suitable for low SINR situations. Optionally, source-channel joint coding can be triggered when SINR is lower than a preset threshold.

The data length before the above-mentioned source-channel joint coding may also be referred to as the source-channel joint coding input data length.

The data length after the above-mentioned source channel joint coding may also be referred to as the output data length of the source channel joint coding. A method for obtaining the data length after the above-mentioned source channel joint coding may be that the UE obtains the output data length value after encoding the data to be transmitted through the candidate source channel joint coding algorithm. The UE determines whether the trigger condition is met according to the data length value. If the condition for triggering the start of the source channel joint coding is met, the data after the source channel joint coding is sent, otherwise the data without the source channel joint coding is sent. .

There are many ways to define the compression rate, such as the data length after the source channel joint coding divided by the data length before the source channel joint coding, or the data length before the source channel joint coding divided by the data length after the source channel joint coding, or 1-the data length after the source channel joint coding/the data length before the source channel joint coding, etc. It can be understood that due to different definitions of the compression rate, the corresponding condition setting logic will also be different (Table 1 only illustrates the threshold setting corresponding to one of the definition methods).

The above-mentioned transmission resource size, transmission resource refers to the transmission resource used to transmit the data. For example, the data size that can be transmitted by UE uplink can be obtained based on UL grant. The above-mentioned transmission resource size can also be determined according to the reporting configuration of the target data in the first message.

The time length of the above-mentioned source channel joint encoding and the time length of the source channel joint decoding may be the processing time for the UE node (second node) to perform source channel joint encoding on the data, or the processing time for source channel joint decoding, or the sum of the processing time for source channel joint encoding and source channel joint decoding.

In an embodiment of the present application, the trigger threshold can be understood as a preset threshold value (threshold), and the trigger threshold can be used in conjunction with an offset value (offset) of the trigger threshold. The offset value can be pre-set or network-configured (for example, configured via a first message). For example, as shown in Table 1. By setting the offset value, the number of times the source channel joint coding is switched on and off can be reduced, or the UE can be prevented from frequently turning on or off the source channel joint coding.

Optionally, the first trigger condition includes at least one of the following:

A first trigger parameter and a first trigger threshold corresponding to the first trigger parameter;

a first identifier of the trigger event, the first identifier corresponding to a second trigger parameter and a second threshold corresponding to the second trigger parameter;

A second identifier of the trigger event and a third threshold corresponding to a third trigger parameter, wherein the second identifier corresponds to the third trigger parameter.

In the embodiment of the present application, the first trigger condition may be set in at least one of the following ways:

1) a first parameter and a first threshold corresponding to the first parameter;

2) Trigger event identification, in this case, which trigger parameters and thresholds the specific event corresponds to are predefined by the protocol;

3) Trigger event identification and corresponding first threshold. In this case, the threshold value is dynamically determined each time configuration is performed.

For example, as shown in Table 1. In Table 1, the event number, parameter and threshold setting are only examples and are not used to limit the embodiments of the present application, wherein the threshold setting of less than can also be replaced by less than or equal to, or greater than can also be replaced by greater than or equal to.

Optionally, the first message is further used to indicate at least one of the following:

Source-channel joint coding algorithm;

The type of the target data;

Characteristics of the target data;

candidate geographic areas;

Reporting configuration of the target data;

The reporting conditions of the target data.

Optionally, the first message includes a source-channel joint coding algorithm indication, which is used to indicate the use of a predefined algorithm or a pre-deployed algorithm in the protocol.

In the embodiment of the present application, the above-mentioned predefined algorithm may be an algorithm pre-set in the communication protocol, and the pre-deployed algorithm may be an operator-defined algorithm.

In an embodiment of the present application, at least one of the type of the target data and the characteristics of the target data can be described as a candidate perception data profile, and the first message can also include at least one of the candidate perception data profile and the candidate geographic area. The candidate perception data profile is used to indicate which types and/or characteristics of perception data can be jointly coded with the source channel. Exemplarily, the perception service data types can be divided into the following types:

a) Radar detection services, including: radar speed measurement, radar distance measurement, radar angle measurement, and radar imaging;

b) User positioning and target tracking services; for example, drone trajectory tracking;

c) Environmental reconstruction business, including: topography reconstruction, building surface reconstruction;

h) Target detection service, which determines whether a target exists or not, including intrusion detection in target sensing areas such as home or outdoor areas.

The candidate geographical area information is used to indicate in which areas source channel coding can be used. The source coding geographical area information is at least one of the following:

a) Cell Global Identifier (CGI), including Public Land Mobile Network (PLMN) ID and Cell ID;

b) Physical cell identity (PCI);

c) Carrier frequency information;

d) Tracking Area Code (TAC);

e) Tracking area identify (TAI), including PLMN ID and TAC;

f) at least one geographical location region, for example, a geographical location region may be identified by a reference point (represented by a geographical coordinate) and a distance threshold, or for example, a geographical location region may be identified by a plurality of geographical coordinates;

g) At least one radio access network area (RAN area), identified by a RAN area ID, including a TAC and a RAN area Code.

The type of target data, the characteristics of the target data, and at least one of the candidate geographic areas can also be combined with the first trigger condition to determine whether to trigger source-channel joint coding. For example, for the candidate perception data profile, source-channel joint coding can be used in the candidate geographic location area when the trigger event is met. Exemplary, as shown in Table 2. At present, the source-channel joint coding algorithm is usually closely related to the characteristics of the source. For example, the source can be divided into two categories according to whether it has structured features, structured sources (typically such as images, videos, and perceptual imaging) and unstructured sources (such as Gaussian sources, etc.). Since the current source-channel joint coding is mostly aimed at structured sources, environmental reconstruction or imaging perception data may be more suitable for source-channel joint coding.

Table 2

In an embodiment of the present application, the first message is used to indicate the reporting configuration of the target data. The reporting configuration of the target data includes the measurement configuration of the target data and at least one of the time-frequency resource configurations used by the reporting data. The measurement configuration of the target data includes the perception data that the UE needs to measure and report, such as RSRP, angle, etc.

In an embodiment of the present application, the first message is used to indicate the reporting conditions of the target data, and the above-mentioned reporting conditions can also be described by a first indicator. The first indicator is used to indicate that only the data that meets the first indicator in the collected data needs to be reported/transmitted. For example, the first indicator can be a perceived SNR, and the perceived SNR refers to the signal-to-noise power ratio of the target signal after the perceived signal is transformed into the delay domain and/or Doppler domain and/or angle domain, for example, it is reported only when the SNR is greater than the first threshold. Similarly, there can also be a "perceived SINR", which is the signal-to-interference-noise power ratio of the target signal after the first signal is transformed into the delay domain and/or Doppler domain and/or angle domain, for example, it is reported only when the SINR is greater than the second threshold.

Optionally, in the case where the first message is used to indicate the first trigger condition of whether the target data uses source-channel joint coding, the first message is further used to indicate at least one of the following:

An offset value of a trigger threshold of the source channel joint coding;

The trigger event determines the time limit;

The number of times the trigger event is judged to be established;

The trigger event is judged to be effective for a certain period of time.

In an embodiment of the present application, an offset value (offset) of a trigger threshold is set. For example, an offset value may be set for a SINR threshold, an offset value may be set for a data length threshold before source channel joint coding, an offset value may be set for a data length threshold after source channel joint coding, an offset value may be set for a compression rate threshold, or an offset value may be set for a time length threshold of source channel joint coding, etc. Referring to the description in the aforementioned embodiment, as shown in Table 1-2, by setting the offset value of the trigger threshold, frequent turning on or off of source channel joint coding may be avoided.

In an embodiment of the present application, in order to avoid frequent opening or closing of the source channel joint coding, or the data of the same perception service adopts different data transmission methods. The above-mentioned first message may also include the number of times the trigger event is judged to be established and the corresponding threshold value. For example, in a certain time interval or in a perception service data transmission, the threshold value of the number of times the event is judged to be established is 1, which means that after the judgment of using the source channel joint coding will be maintained in the corresponding time interval, it can also be understood that it is valid within the preset time after the trigger event is judged to be established, which not only avoids frequent opening or closing, but also the UE does not need to make a judgment every time before sending data. Alternatively, the trigger event judgment time limit and conditions can be set. For example, the source channel joint coding trigger parameter is the average value over a period of time, or the parameter values at X consecutive moments meet the conditions. Taking SINR as an example, in order to avoid frequent opening or closing, the following method can be used:

Count the SINRs over a period of time or at several consecutive measurement moments. If the average value meets the conditions, turn on or off the channel source joint coding.

The SINRs for a period of time or for several consecutive measurement moments are counted. If the SINRs for X consecutive measurement moments meet the conditions, or the SINRs for Y ms consecutively meet the conditions, the channel-source joint coding is turned on or off.

Optionally, the method further includes:

The terminal sends terminal capability information to the network side device;

The terminal capability information indicates at least one of the following:

Whether the terminal supports source-channel joint coding;

The source-channel joint coding algorithm supported by the terminal.

In an embodiment of the present application, the UE capability information indicates whether the UE supports source-channel joint coding. In the case of supporting source-channel joint coding, it may optionally indicate support for standard algorithms and/or support for operator-defined algorithms. In the case of supporting operator-defined algorithms, it may optionally indicate the algorithm version and operator PLMN. The source-channel coding algorithm identifier may also be represented by the AI model identifier used for the source-channel joint coding.

Optionally, in the case where the terminal supports the operator-defined algorithm, the terminal capability information is further used to indicate the operator-defined algorithm version and the operator's public land mobile network PLMN.

For the network side device, the network side device receives the terminal capability information sent by the terminal, and the network side device determines the first message according to the terminal capability information. That is, the first message can be determined by the network side device according to the terminal capability information.

Optionally, the first message may be determined by the network side device according to at least one of the terminal capability information and the service quality parameter requirement.

In an embodiment of the present application, the above-mentioned service quality parameter requirements can be understood as performance indicators corresponding to specific services, such as the reasoning performance corresponding to the reasoning service, or, for example, the positioning accuracy requirement is that the error does not exceed 1 cm, etc.

Optionally, when the target data is perception data, the service quality parameter requirement includes at least one of the following:

Positioning accuracy;

Speed accuracy;

Perceived resolution;

Refresh rate;

Probability of missed detection;

False alarm probability;

Recognition accuracy;

Maximum perceived service delay.

In the embodiment of the present application, when the target data is perception data, the service quality parameter requirement may also be referred to as perception service QoS, which is used to indicate the demand for perception service quality and can be used to determine whether the data is transmitted correctly, and may include at least one of the following definition methods:

Positioning accuracy (including horizontal accuracy and vertical accuracy): describes the closeness between the measured perception result (i.e. position) of the target object and its true position value. It can be further derived into horizontal perception accuracy and vertical perception accuracy. The former refers to the perception result error on the two-dimensional reference plane or horizontal plane, and the latter refers to the perception result error on the vertical axis or height.

Speed accuracy (including horizontal accuracy and vertical accuracy): describes the degree of closeness between the measured perception of the target object's speed (i.e., speed) and its true speed;

Perceptual resolution: describes the minimum difference in the magnitude of the target object measurement (such as distance, speed) to allow objects of different magnitudes to be detected;

Refresh rate: describes the rate at which sensing results are generated. It is the inverse of the time interval between two consecutive sensing results;

Missed detection probability: describes the ratio of missed detection events to all events of obtaining sensor results in any predetermined time period when the system attempts to obtain sensor results. It is only applicable to binary judgment sensor results;

False alarm probability: describes the ratio of events that do not represent target objects or environmental features to all events detected in any predetermined time period when trying to obtain sensing results. It is only applicable to perception results of binary judgments;

Recognition accuracy: describes the probability of correctly identifying the perceived target category;

Maximum perception service latency: describes the time from triggering the required perception result to providing the perception result at the perception system interface.

In an embodiment of the present application, the service quality parameter requirement can be determined by the access network node itself, or it can be determined by the access network node based on information sent by the core network device or the network management device.

In an embodiment of the present application, the wireless access network node updates the source channel joint coding configuration according to the perceived service quality parameter requirements (or referred to as perceived performance indicators). Depending on the perception scenario (such as target recognition, target tracking, environmental reconstruction, etc.), the transmitted perception data may involve one or more of the perception performance indicators. A method for updating the source channel joint coding configuration is to update the source channel joint coding algorithm or the source channel joint coding trigger condition based on whether the perception performance indicator meets the requirements. For example, by replacing the autoencoder (AI model) with different numbers of coding layers and/or iterations, source channel joint coding performance with different performance can be achieved. The above-mentioned update process may be a process of sending a first message, or may be updated during the sending process of other messages.

Optionally, the first message is used to indicate at least one of a first format of a first physical channel and a resource corresponding to the first format of the first physical channel; wherein the first format of the first physical channel adopts source-channel joint coding;

Alternatively, the first message is used to indicate a target format of a second physical channel and at least one of the resources corresponding to the target format of the second physical channel; wherein the second physical channel includes at least one of a second format and a third format, and the target format is at least one of the second format and the third format; the second format of the second physical channel adopts source-channel joint coding; the third format of the second physical channel adopts source and channel independent coding.

In the embodiment of the present application, the first physical channel and the second physical channel may be uplink physical channels or downlink physical channels.

Optionally, the second physical channel is a physical uplink channel or a physical downlink channel.

In the embodiment of the present application, since the format of the physical channel corresponds to the encoding method, the encoding method of the target data can be determined by indicating the format of the physical channel. It can be understood that the first message determines the encoding method of the target data uplink or downlink by indicating the format of the physical channel, or determines whether to use source channel joint encoding.

Optionally, the first physical channel is a physical uplink control channel PUCCH or a physical downlink shared channel PDSCH.

In the embodiment of the present application, the second physical channel and the first physical channel may be different physical channels. It can be understood that the second physical channel is a physical uplink signal or a physical downlink channel defined independently of a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

Optionally, the method further includes:

The terminal receives a fourth message sent by the network side device;

The fourth message is used to indicate activation of at least one of the first format of the first physical channel and the resources corresponding to the first format of the first physical channel;

Alternatively, the fourth message is used to indicate activation of at least one of a target format of the second physical channel and resources corresponding to the target format of the second physical channel.

In the embodiment of the present application, after receiving at least one of the physical channel formats and format resources indicated by the first message, the terminal may also activate at least one of the physical channel formats and format resources based on the fourth message. For example, at least one of multiple physical channel formats and multiple format resources is indicated in the first message, and at least one of the multiple formats is activated using the fourth message.

In an embodiment of the present application, the network side device may send a fourth message to the terminal when the second trigger condition is met; the fourth message is used to indicate activation of at least one of the first format of the first physical channel and the resources corresponding to the first format of the first physical channel; or, the fourth message is used to indicate activation of at least one of the target format of the second physical channel and the resources corresponding to the target format of the second physical channel. The above-mentioned network side device may first configure the physical channel format and/or format resources through the first message, and then, when the second trigger condition is met, activate at least part of the above-mentioned configuration, which can improve the timeliness of the configuration. The setting method of the above-mentioned second trigger condition is similar to the above-mentioned first trigger condition, and there may also be at least one of the corresponding trigger parameters, trigger events and trigger thresholds. For example, it may be channel quality information, or parameters such as the perception data situation that the UE needs to report, and whether to send the fourth message for triggering is determined based on whether the above-mentioned parameters meet the conditions.

In the embodiment of the present application, the physical channel and/or physical channel format that supports source-channel joint coding can have the characteristics of high real-time performance and high efficiency. In the embodiment of the present application, because the physical channel transmission has the characteristics of high real-time performance, it can save the protocol functions of the wireless access network layer 2 and layer 3 that may be involved in the existing protocol during the data transmission process, and also save the protocol functions of the core network node. At the same time, the source-channel joint coding can effectively reduce the amount of data transmission for specific target data, and is therefore more suitable for situations with low signal-to-noise ratios and situations where data transmission overhead is reduced.

Step 202: The terminal determines at least one of a target encoding mode and a target decoding mode of target data according to the first message.

In an embodiment of the present application, the terminal determines at least one of a target encoding method and a target decoding method of the target data according to the first message. In other words, the UE receives the first message, and determines whether to use source channel joint encoding according to the first message. The above-mentioned determination of whether to use can be that the terminal determines whether the uplink transmission process uses source channel joint encoding, or it can be that the terminal determines whether the downlink reception process uses source channel joint decoding. According to the existing protocol positioning habits, the encoding method is usually indicated. Here, for the case of downlink reception of the terminal, the target decoding method of the downlink data reception of the terminal can be implicitly indicated by indicating the target encoding method of the downlink data.

Optionally, the method further includes:

The terminal sends a second message to the network side device;

The second message includes at least one of the following:

target data encoded using the target encoding method;

Indication of whether to use source-channel joint coding.

In an embodiment of the present application, optionally, the terminal may determine whether the uplink target data (e.g., perception data) adopts source channel joint coding based on the first message. After the terminal determines whether to use source channel joint coding to send the target data, that is, after determining the target coding method (e.g., source channel joint coding or source channel independent coding), the terminal may directly use the target coding method to encode the target data, and send the encoded target data to the network side device, or may first send an indication information to the network side device to indicate the target coding method determined by the terminal, or send an indication information indicating whether to use source channel joint coding.

Optionally, when the second message includes indication information of whether to use source channel joint coding, the method further includes:

The terminal receives the reporting configuration of the target data sent by the network side device;

The target data is sent to the network side device according to the target data reporting configuration and the target encoding mode.

In an embodiment of the present application, the network side device receives a second message sent by the terminal; the second message includes at least one of the following: target data encoded using a target coding method, wherein the target coding method is a coding method of the target data determined by the terminal according to the first message; indication information of whether to use source channel joint coding. In the case where the second message includes target data encoded using a target coding method, the network side device decodes the target data according to the target coding method; in the case where the second message includes indication information of whether to use source channel joint coding, the network side device sends a reporting configuration of the target data to the terminal. The terminal can send the target data to the network side device according to the target data reporting configuration and the target coding method. For the above target data reporting configuration, please refer to the description of the above embodiment. It can be understood that the above target data reporting configuration can be sent in the first message, or it can be sent to the terminal by the network side after receiving the above second message.

In an embodiment of the present application, the UE sends a second message to the wireless access network node, wherein the second message includes data that is jointly encoded by the source channel, and/or indicates whether the source channel is jointly encoded. Optionally, the second message may also include a source channel joint encoding algorithm indication, which is used to indicate which predefined algorithm or pre-deployed algorithm in the protocol is used.

Optionally, when the target coding mode is source-channel joint coding, the second message further includes: source-channel joint coding algorithm indication information.

Optionally, the method further includes:

The terminal receives a third message sent by the network side device, where the third message includes target data encoded by using the target encoding method;

The third message is decoded according to a decoding method corresponding to the target encoding method or the target decoding method.

In the embodiment of the present application, optionally, the terminal may determine whether the downlink target data (for example, the perception data) adopts source-channel joint coding based on the first message. When receiving the target data (the third message), the terminal may decode the target data based on the decoding method corresponding to the determined target coding method or the target decoding method to obtain the decoded data of the third message.

Optionally, the method further includes: the terminal sends feedback information to the network side device, and the feedback information is used to indicate whether the data after decoding the third message meets the service quality parameter requirements. For example, taking positioning accuracy as an example, the terminal requires that the error of horizontal accuracy and vertical accuracy is not greater than 1 cm, then the UE determines whether the positioning result generated based on the received data meets the accuracy requirement. If the required accuracy is achieved, the service quality requirement is fed back. Otherwise, the service quality requirement is not met.

The above-mentioned service quality parameter requirements can be obtained by the terminal side through the application function of the terminal, or the protocol function of the terminal side is determined according to the demand, or the terminal can obtain the service quality parameter requirements from the access network node.

In order to facilitate understanding of the embodiments of the present application, the optional implementation schemes of the above embodiments are described below based on several examples.

Example 1: PUCCH format supporting perception data reporting.

This embodiment describes the reporting of perception data supporting source channel joint coding through the first format of PUCCH. At present, different channel coding schemes are used according to different PUCCH formats. Specifically, PUCCH format 1/1a/1b adopts a repetition coding scheme, PUCCH format 2/2a/2b adopts a Reed-Muller coding scheme, and PUCCH format 3/4/5/6 adopts a Polar coding scheme. The above PUCCH formats are used for independent coding of source channels. In this embodiment of the present application, a new PUCCH first format is added, and the PUCCH first format adopts source channel joint coding. A source channel joint coding method can be a source channel joint coding method based on an autoencoder.

The following is a brief description of the interaction process between the UE and the network side device in Example 1:

Step 1: The network side device sends a first message to the UE, and the first message is used to indicate whether the internal data (perception data) of the mobile network uses source channel joint coding. This embodiment assumes that the first format of PUCCH adopts source channel joint coding. Therefore, an example of a first message is the control signaling of the control plane. For example, at least one of the PUCCH first format and the PUCCH first format resources is configured through PUCCH-Config/PUCCH-ConfigCommon/PUCCH-CongfigurationList. In addition, an example of a first message is to configure at least one of the PUCCH first format and the PUCCH first format resources through the DCI carried by the downlink control channel PDCCH. In addition, an example of a first message is to configure multiple PUCCH format parameters through Radio Resource Control (RRC), wherein the multiple PUCCH format parameters include at least the PUCCH first format, and then the radio access network node indicates activation of at least one of the PUCCH first format and the PUCCH first format resource through the Media Access Control Control Element (MAC CE) based on the channel quality information (for example, based on channel reciprocity, the radio access node measures the channel quality based on information such as uplink signal SNR or SINR) and the perceived data situation that needs to be reported by the UE (for example, data size). It should be noted that the PUCCH first format here adopts source-channel joint coding based on the protocol definition.

Optionally, the first message includes a source-channel joint coding algorithm indication, which is used to indicate which predefined algorithm or pre-deployed algorithm in the protocol is used. For example, one algorithm is the aforementioned source-channel joint coding based on the autoencoder, and the other algorithm is a deep learning source-channel joint coding algorithm based on CNN.

Step 2: The UE receives the first message, and processes the perception data based on the first message, including at least source-channel joint coding.

Step 3: The UE sends a second message to the wireless access network node, where the second message uses the first format of the PUCCH.

Step 4: The wireless access network node receives the second message and performs source-channel joint decoding.

Step 5: Optionally, the wireless access network node updates the source-channel joint coding configuration according to the perceived performance indicator (also called the perceived service quality parameter), for example, updating the source-channel joint coding algorithm according to the position accuracy of the environmental reconstruction.

Example 2: A second physical channel supporting sensing data reporting

This embodiment describes supporting data transmission within the mobile network through a second physical channel. Compared with the LPP solution, this embodiment only involves physical layer processing of the second physical channel, saving the protocol functions of the existing protocol wireless access network layer 2 and layer 3, and also saving the protocol functions of the core network node. Especially for perception-assisted communication, considering that the time slot and subframe interval of the communication do not exceed the millisecond level, the second physical channel can provide higher real-time performance and improve efficiency.

In this embodiment, the second physical channel at least supports the source-channel joint coding, and the optional second physical channel can also support the two modules of source coding and channel coding to be independent. When the source coding and channel coding are independent of each other, potential channel coding methods include low-density parity check (LDPC), Polar, Turbo, fountain, etc., and source coding is an optional function. If source coding is included, refer to the Internet Engineering Task Force Request For Comments (IETF RFC) series of documents, and the potential lossless source coding is as follows:

1) DEFLATE: A widely used lossless compression algorithm, commonly used in file formats such as ZIP and GZIP. This source coding algorithm is used in the existing protocol UDC;

2) LZ77/LZ78: A dictionary-based lossless compression algorithm, commonly used in file formats such as LZW and ZIP;

3) Brotli: A lossless compression algorithm with high compression ratio and fast decompression. It has become one of the standards for Web content compression.

4) Zstandard: A lossless compression algorithm with high compression ratio and fast decompression, which has become one of the standards in many application fields;

5) LZ4: A lossless compression algorithm with high compression speed and fast decompression. It is often used in scenarios such as real-time data transmission and high-speed caching.

6) Snappy: A lossless compression algorithm with high compression speed and fast decompression. It is often used in scenarios such as big data processing and real-time data transmission.

If the second physical channel supports both source channel joint coding and the two modules of source coding and channel coding are independent. Assume that the second format of the second physical channel adopts source channel joint coding, and the third format of the second physical channel adopts only channel coding (such as LDPC). Accordingly, one configuration method is to configure the second format of the second physical channel (turn on source channel joint coding) under low SNR conditions, and configure the third format of the second physical channel (adopting the channel coding method in which source coding and channel coding are independent) under high SNR conditions.

The following is a brief description of the interaction process between the UE and the network side device in Example 2:

Step 0: Optionally, the UE sends UE capability information to the network side device. The capability information at least includes that the UE supports the second physical channel. When the UE supports the second physical channel, optionally, the capability information may also include at least one of the second physical channel formats supported by the UE, the source channel joint coding algorithms of each second physical channel format, and the channel coding algorithms of each second physical channel format. Optionally, the capability information may also include whether the UE supports the operator-defined source channel joint coding. Considering that the UE may have multiple cards of different operators, the algorithm version information and the corresponding PLMN identifier must be indicated for the operator-defined source channel joint coding algorithm.

Step 1: The network side device sends a first message to the UE, and the first message is used to indicate whether the internal data (perception data) of the mobile network uses source channel joint coding. This embodiment assumes that the second physical channel at least supports source channel joint coding, so an example of the first message is the control signaling of the control plane. For example, the second physical channel and at least one of the second physical channel resources are configured based on the configuration field of the physical channel in the protocol. In addition, an example of the first message is to configure the second physical channel and/or the second physical channel resource through the DCI carried by the downlink control channel PDCCH. In addition, an example of the first message is to configure multiple format parameters of the second physical channel (such as the aforementioned second format and third format) through RRC, and the multiple formats of the second physical channel at least include the second physical channel second format supporting source channel joint coding, and then the wireless access network node indicates the activation of the second physical channel second format and at least one of the second physical channel second format resources through MAC CE according to the channel quality information (for example, based on channel reciprocity, the wireless access node measures the channel quality according to information such as uplink signal SNR or SINR) and the perception data situation that needs to be reported by the UE (such as data size). It should be noted that, here, the second format of the second physical channel may adopt source-channel joint coding based on protocol definition.

Optionally, the first message includes a source-channel joint coding algorithm indication, which is used to indicate which predefined algorithm or pre-deployed algorithm in the protocol is used, such as the algorithm described in Example 1.

Step 2: The UE receives the first message, and processes the perception data based on the first message.

Step 3: The UE sends a second message to the wireless access network node, where the second message uses the second physical channel configured by the first message.

Step 4: The wireless access network node receives the second message and performs reception processing on the second physical channel.

Step 5: Optionally, the wireless access network node updates the source-channel joint coding configuration of the second physical channel according to the perceived performance indicator (also called the perceived service quality parameter, see explanation 1), for example, updating the source-channel joint coding algorithm according to the position accuracy of the environmental reconstruction.

Example 3: Condition-based perception data reporting

The difference between this example and Example 1 is that the UE determines whether to use the source-channel joint coding based on the conditions configured on the network side and according to the perception data collection situation.

The following is a brief description of the interaction process between the UE and the network side device in Example 3:

Step 1: The network side device sends a first message to the UE, wherein the first message includes at least a source channel joint coding trigger condition. The source channel joint coding trigger condition includes a source channel coding trigger parameter and/or a trigger event type and a corresponding threshold value. An example includes one or more items as shown in the aforementioned Table 2 (each item in the table is only an example, wherein the possible meaning options of each field and the combination between different fields may be other, without limitation).

Step 2: The UE receives the first message, and determines whether to perform source-channel joint coding according to whether a trigger condition indicated in the first message is met. Optionally, the source-channel joint coding algorithm is determined according to whether the trigger condition indicated in the first message is met.

Step 3: The UE sends a second message, wherein the second message at least includes an indication of whether the source channel is jointly coded. When the source channel is coded, the second message may also include a source channel joint coding algorithm.

Step 4: The wireless access network node receives the second message, and sends a perception data reporting configuration according to the second message. The perception data reporting configuration is mainly used to indicate a perception data reporting resource. If PUCCH reporting is used, a configuration method is shown in step 1 in Example 1.

Step 5: The UE receives the perception data reporting configuration and sends the perception data jointly encoded by the source channel.

Step 6: The wireless access network node receives the sensing data and performs source-channel joint decoding.

Step 7: Optionally, the wireless access network node updates the source-channel joint coding trigger condition configuration according to the perceived performance indicator (also called perceived service quality parameter, see Explanation 1).

Example 4: A method for UE to receive target data

This embodiment describes a method for a UE to receive a perception number through a downlink channel. This method is also applicable to situations where the UE receives an AI model, etc., which has high real-time requirements, large data volumes, or low SINR. The downlink channel may be a PDSCH channel or a newly added first downlink physical channel. The PDSCH needs to be extended to support source channel joint coding based on the existing channel coding method, or the newly added first downlink physical channel needs to support source channel joint coding.

The following is a brief description of the interaction process between the UE and the network side device in Example 4:

Step 1: The network side device sends a first message to the UE, where the first message is used to indicate whether the internal data (perception data) of the mobile network uses source channel joint coding. This embodiment assumes that one option supported by PDSCH is source channel joint coding, so an example of a first message can be configured by downlink control information DCI, indicating that the PDSCH is source channel joint coding.

Optionally, the first message includes a source-channel joint coding algorithm indication, which is used to indicate which predefined algorithm or pre-deployed algorithm in the protocol is used. For example, one algorithm is the aforementioned source-channel joint coding based on the autoencoder, and the other algorithm is a deep learning source-channel joint coding algorithm based on CNN.

Step 2: The UE receives the first message, and processes the perception data based on the first message, including at least source-channel joint decoding.

Step 3: The UE sends source channel joint decoding feedback information to the wireless access network node. The source channel joint decoding feedback information is used to indicate whether the received perception data meets the required perception performance indicator requirements (quality of service parameter requirements).

Step 4: The wireless access network node receives the feedback information and determines whether to update the source-channel joint coding configuration, such as modifying the parameters of the source-channel joint coding or modifying the algorithm of the source-channel joint coding.

In an embodiment of the present application, a terminal receives a first message sent by a network-side device; the terminal determines at least one of a target encoding method and a target decoding method of target data according to the first message; wherein the first message is used to indicate at least one of the following: whether the target data uses source-channel joint encoding; and a first trigger condition for whether the target data uses source-channel joint encoding. In an embodiment of the present application, the terminal can determine whether to use source-channel joint encoding for data transmission based on the above-mentioned first message, which can enrich the diversity of data transmission encoding methods and thereby improve the transmission efficiency of the target data.
