For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

The data transmitted inside the 5G and 6G mobile networks have a lot of mobile network internal data such as positioning data, perception data, AI model training data, etc., in addition to user data.

The perception data relates to a communication perception fusion technology, on one hand, the technology improves the perception accuracy, improves the perception timeliness and realizes the seamless ubiquitous perception service by means of a communication system, and on the other hand, the technology further improves the performance of the wireless communication system based on the perception, the identification and the prediction of the wireless communication channel environment, and builds an intelligent network in an assisted manner. Regarding the perceptually assisted communication, potential examples include reconstructing an environment between a base station and a terminal (UE) based on the perceptions, and assisting the utilization of channel estimation or non-line of sight (Non Line of Sight, NLOS) signals based on the reconstructed information. Examples of potential perceptually assisted communications currently discussed in the industry include perceptually assisted beam management, perceptually assisted channel estimation enhancement, perceptually assisted positioning, and the like. In the case of perceptually assisted communication, considering that the time slot and subframe interval of the communication does not exceed the order of milliseconds, the perceptually assisted communication generally has higher real-time requirements, and requires that the smaller the overhead introduced by the perceptually assisted communication, the better.

The embodiment of the application designs a corresponding technical scheme for data transmission in a mobile network, in particular for data in the mobile network with high requirement on data transmission real-time and low cost, which is oriented to similar perception auxiliary communication.

Conventional communication systems implement transmission of user plane data (e.g., image/video/text/voice) by source coding, channel coding, and divide the source and channel coding into two modules designed independently. The signal source channel independent coding (SSCC) has the characteristics of simple design and modularization, but in an actual communication system, the tolerable delay, complexity and code length of the system are limited, and the assumption that the code length is not limited in shannon separation theorem is difficult to satisfy. The separation theorem is applicable to the point-to-point communication system and the case where the source and channel distribution are known, but the separation theorem is not applicable in the scenarios such as multi-user communication and mobile communication with a time-varying channel. The research on the joint coding of the source channel shows that, for a specific purpose, the joint coding of the source channel can effectively reduce the data volume transmitted by the joint coding of the source channel under the condition of meeting the same service quality requirement, for example, under the condition of the same peak Signal-to-Noise Ratio (PSNR), so that the joint coding of the source channel has a gain under the condition of low Signal-to-Noise Ratio (SNR) or under the condition of hopefully reducing transmission overhead.

The prior protocol standard does not adopt the source channel joint coding technology, and the embodiment of the application designs a corresponding technical scheme for executing the flow of the source channel joint coding technology on the data transmitted by the mobile network. The embodiment of the application is illustrated by taking the internal data of the mobile network as an example. It can be appreciated that this solution is applicable both to user data of existing applications and to data inside the mobile network. Different from the user data borne by the 5G network user plane, the data in the mobile network is mainly used by UE, a radio access network node and a core network node, and is used for providing services for the outside of the network, such as network self optimization or network capability opening.

The coding configuration method, device, terminal, equipment and medium provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a code configuration method provided by an embodiment of the present application, for a terminal, as shown in fig. 1, where the method includes the following steps:

Step 201, a terminal receives a first message sent by network side equipment, wherein the first message is used for indicating at least one of whether the target data uses source channel joint coding or not and whether the target data uses a first trigger condition of the source channel joint coding or not.

In the embodiment of the present application, the network side device may be a radio access network node, or may be described as a first node. The network side equipment sends a first message to the UE, wherein the first message is used for indicating whether the target data uses at least one of the triggering conditions of the source channel joint coding or not. The target data may be mobile network internal data, or user data applicable to existing applications.

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

Optionally, the embodiment of the application is applicable to the internal data of the mobile network, especially the data with the characteristics of large data volume, high real-time requirement and the like, namely, the target data comprises the internal data of the mobile network. Perceptually assisted communication typically has higher real-time requirements and requires less overhead to be introduced by the perceptually assisted communication. The embodiment of the application is suitable for a perception data transmission method of perception auxiliary communication, and the perception data transmission method can support information source channel joint coding based on the indication of the first message. The method in the embodiment of the application is also suitable for other data with large data volume and high real-time requirement characteristics in the mobile network, such as AI model, AI model training data and the like.

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

1) Transmitting and receiving data terminated in any two of the terminal, the radio access network device and the core network device;

it may also be described as data where the peer-to-peer protocol of transmission and reception is located in the UE, radio access network or core network.

The peer-to-peer protocol layers, e.g. long term evolution positioning protocol (LTE Positioning Protocol, LPP), are located in the data of the location management functions (location management function, LMF) of the UE and the core network, respectively, the peer-to-peer protocol layers, e.g. radio resource control (Radio Resource Control, RRC), are located in the data of the UE and the radio access network device (eNB/gNB, base station), respectively, and the data plane protocol layers are located in the data of the UE and the radio access network device, or in the UE and the core network device, respectively.

2) Data terminating at any one of the terminal, the radio access network device, or the core network device is transmitted or received.

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

The terminal (UE) related to the mobile network content data refers to a protocol function of a User equipment (User equipment) defined by a 3GPP protocol, and does not include an application function.

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

The embodiment of the application is suitable for 5G,6G and future communication systems.

In the embodiment of the application, the sensing data comprises at least one of sensing measurement report, sensing measurement result validity indication and sensing auxiliary data. The sensing measurement report is mainly a measurement result obtained after the sensing measurement quantity is measured, and the sensing auxiliary data comprises an environment map, target area information and the like.

Illustratively, the perceived measurement may be classified into the following 4 classes (this example focuses on illustrating the measurement, the 4 classes are merely illustrative, and may be classified into 3 classes or not, etc.). The following third and fourth level measurements are also commonly referred to as sensing results, and the second level and/or first level measurements are referred to as sensing measurement data, depending on the relationship of the sensing measurement to the sensing traffic:

a) The first-stage measurement quantity (received signal/original channel information) comprises a received signal/channel response complex result, amplitude/phase, an I/Q path and operation results thereof (operation comprises addition, subtraction, multiplication, matrix addition, multiplication, matrix transposition, trigonometric relation operation, square root operation, power operation and the like, and threshold detection results, maximum/minimum value extraction results and the like of the operation results, and the operation also comprises fast Fourier transform (Fast Fourier Transform, FFT)/inverse fast Fourier transform (INVERSE FAST Fourier Transform, IFFT), discrete Fourier transform (Discrete Fourier Transform, DFT)/inverse discrete Fourier transform (INVERSE DISCRETE Fourier Transform, IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform, digital filtering and the like, and threshold detection results, maximum/minimum value extraction results and the like of the operation results;

b) Second-order measurements (basic measurements) including delay, doppler, angle, signal strength, and multi-dimensional combined representations thereof;

c) Third level measurements (basic properties/states) including distance, speed, angle/orientation, radar cross sectional area (Radar Cross Section, RCS), acceleration;

d) Fourth level measurement (advanced properties/status) including spatial location, whether or not the target is present, trajectory, motion, expression, vital sign, quantity, imaging result, weather, air quality, shape, texture, composition.

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

Optionally, in an embodiment of the present application, the first message is used to indicate whether the target data uses a first trigger condition of source channel joint coding. The network side equipment sends a first trigger condition to the UE, so that the UE determines whether to execute source channel joint coding or not based on the trigger condition.

Optionally, the condition parameters of the first trigger condition include at least one of:

triggering parameters of the source channel joint coding;

triggering threshold of joint coding of information source channels;

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

In the embodiment of the present application, the first trigger condition may be obtained by at least one combination of a trigger parameter, a trigger threshold and a trigger event. Or, the source channel joint coding triggering condition includes at least one of a source channel joint coding triggering parameter, a triggering event type and a corresponding threshold value.

The first trigger condition includes at least one of:

the first trigger sub-condition is used for starting the source channel joint coding;

and the second trigger sub-condition is used for closing the source channel joint coding.

It can be appreciated 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 several usage cases:

1) The default UE does not start the source channel joint coding, and the UE judges whether to start the source channel joint coding for data transmission based on at least one of the trigger parameters and the corresponding trigger threshold and the trigger event;

2) The default UE is to start the source channel joint coding, and the UE judges whether to close the source channel joint coding or not based on at least one of the trigger parameters and the corresponding trigger threshold and the trigger event;

3) The UE judges to open or close the source channel joint coding based on the trigger threshold corresponding to the trigger parameter or the trigger condition.

For example, as shown in table 1, the above-described trigger conditions may include at least one of an on condition (entrance condition) and an off condition (exit condition).

Optionally, the triggering parameters of the source channel joint coding include at least one of the following:

a channel quality index;

The data length before the joint coding of the information source channel;

The data length after the joint coding of the information source channel;

compression ratio;

Transmission resource size;

the time length of the joint coding of the information source channels;

the time length of the joint decoding of the information source channels;

the sum of the time length of source channel joint coding and source channel joint decoding.

In the embodiment of the present application, the channel Quality index may be parameters such as a signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), a reference signal Quality (REFERENCE SIGNAL RECEIVING Quality, RSRQ), a reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP), etc., if SINR is taken as an example, the SINR refers to an uplink and/or downlink channel signal to interference plus noise ratio, and the source channel joint coding is generally more suitable for a low SINR case, and optionally, the source channel joint coding may be triggered when the SINR is lower than a preset threshold.

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

The data length after the source channel joint coding can also be called as the output data length of the source channel joint coding, and the method for acquiring the data length after the source channel joint coding can ensure that the UE obtains the output data length value after coding the data to be transmitted through a candidate source channel joint coding algorithm, judges whether the triggering condition is met according to the data length value, if the triggering condition is met, the data after the source channel joint coding is transmitted, and otherwise, the data not subjected to the source channel joint coding is transmitted. .

The compression rate may be defined in various ways, for example, the data length after the source channel joint coding is divided by the data length before the source channel joint coding, or the data length before the source channel joint coding is divided by the data length after the source channel joint coding, or the data length after the 1-source channel joint coding/the data length before the source channel joint coding, etc. It will be appreciated that, due to the different definition of compression ratios, the corresponding condition setting logic will also correspond differently (only one of which is illustrated in table 1 as a threshold setting).

The transmission resource size refers to a transmission resource used for transmitting the data, for example, a size of data that can be obtained by uplink transmission of the UE based on UL grant, and the transmission resource size may be determined according to a reporting configuration of the target data in the first message.

The time length of the source channel joint coding and the time length of the source channel joint decoding may be the processing time of the UE node (second node) for performing the source channel joint coding on the data, or the processing time of the source channel joint decoding, or the sum of the processing time of the source channel joint coding and the source channel joint decoding.

In the embodiment of the present application, the trigger threshold may be understood as a preset threshold (threshold), and the trigger threshold may be used in combination with an offset value (offset) of the trigger threshold. The offset value may be preset, or may be configured by the network (for example, configured by the first message). Exemplary, as shown in table 1. The frequency of switching on and off the source channel joint coding can be reduced or the UE is prevented from frequently switching on or off the source channel joint coding by setting the offset value.

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

The device comprises a first trigger parameter and a first trigger threshold corresponding to the first trigger parameter;

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

the 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 setting of the first triggering condition may adopt at least one of the following modes:

1) A first threshold corresponding to the first parameter;

2) Trigger event identification, in which case specific events correspond to which trigger parameters and threshold values are protocol predefined;

3) The trigger event identification and corresponding first threshold, in which case the threshold value is dynamically determined for each configuration.

Exemplary, as shown in table 1. In table 1, the event number, parameter, and threshold (Thresh) settings are merely examples, and are not intended to limit embodiments of the present application, wherein the threshold settings may be less than or equal to, or greater than or equal to, alternatively greater than or equal to.

The type of the target data;

Characteristics of the target data;

In the embodiment of the present application, the predefined algorithm may be an algorithm preset in a communication protocol, and the pre-deployment 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 characteristic of the target data may be described as a candidate perception data profile, and the first message may further include at least one of a candidate perception data profile and a candidate geographic area. The candidate perceptual data profile is used to indicate which types and/or characteristics of perceptual data may be source channel jointly encoded. Illustratively, the perceived service data types can be divided into the following:

a) Radar detection business comprises radar speed measurement, radar ranging, radar angle measurement and radar imaging;

At least one of the type of the target data, the characteristics of the target data, and the candidate geographic area may also be combined with the first trigger condition to determine whether to trigger source channel joint coding. For example, for candidate perceptual data profiles, source channel joint coding may be used in candidate geographic location areas when a triggering event is satisfied. Exemplary, as shown in table 2. Current source channel joint coding algorithms are generally closely related to the characteristics of the source, e.g., the source can be divided into two classes according to whether it has structured features, structured sources (typically image, video, perceptual imaging) and unstructured sources (e.g., gaussian sources, etc.). Since the current source channel joint coding is multi-targeted to structured sources, environmental reconstruction or imaging class-aware data may be more suitable for source channel joint coding.

TABLE 2

In the 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 comprises at least one of measurement configuration of the target data and time-frequency resource configuration used by the reporting data. The measurement configuration of the target data includes sensing data, such as RSRP, angle, etc., that needs to be measured and reported by the UE.

In the embodiment of the present application, the first message is used to indicate a reporting condition of the target data, where the reporting condition may also be described by a first index. The first index is used for indicating that the data meeting the first index in the collected data is required to be reported/transmitted. For example, the first indicator may be a perceived SNR, where the perceived SNR refers to a signal-to-noise power ratio of the target signal after the perceived signal is transformed into the delay domain and/or the doppler domain and/or the angle domain, e.g., the SNR is reported when the SNR is greater than the first threshold. Similarly, there may be a "perceived SINR" where the signal to interference plus noise power ratio of the target signal is reported after the first signal is transformed into the delay domain and/or the doppler domain and/or the angle domain, e.g., SINR is greater than a second threshold.

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

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

Judging timeliness of the triggering event;

The trigger event is judged to be true times;

and judging the effective duration by the triggering event.

In the embodiment of the present application, the offset value (offset) of the trigger threshold may be, for example, an offset value is set for the threshold of SINR, an offset value is set for the data length threshold before the source channel is jointly encoded, an offset value is set for the data length threshold after the source channel is jointly encoded, an offset value is set for the compression rate threshold, or an offset value is set for the time length threshold for the source channel is jointly encoded, and by referring to the description in the foregoing embodiment, as shown in table 1-2, frequent opening or closing of the source channel is avoided by setting the offset value of the trigger threshold.

In the embodiment of the application, in order to avoid frequently starting or stopping source channel joint coding, or adopting different data transmission methods for the data of the same sensing service. The first message may further include a trigger event determination establishment number and a corresponding threshold value. For example, the threshold value of the number of times of event judgment establishment is 1 in a certain time interval or in certain perceived service data transmission, which means that the judgment is kept in use in a corresponding time interval after adopting the source channel joint coding, and the judgment can be understood as effective in a preset time after the trigger event judgment establishment, thereby avoiding frequent opening or closing and avoiding the need of judging before the UE transmits data each time. Or the trigger event judging timeliness and conditions can be set, for example, the source channel joint coding trigger parameters are average values in a statistical period of time, or parameter values of continuous X moments all meet the conditions. Taking SINR as an example, to avoid frequent turning on or off, the following method may be adopted:

Counting SINR (signal to interference plus noise ratio) in a period of time or at a plurality of continuous measurement moments, and if the average value meets the condition, starting or closing channel source joint coding;

And counting SINR (signal to interference plus noise ratio) of a period of time or a plurality of continuous measuring moments, and if the SINR of the continuous X measuring moments meets the condition or the SINR of the continuous Yms meets the condition, starting or closing the channel source joint coding.

Optionally, the method further comprises:

wherein the terminal capability information indicates at least one of:

Whether the terminal supports source channel joint coding or not;

And the information source channel joint coding algorithm supported by the terminal.

In the embodiment of the 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 also be indicated that standard algorithms are supported, and/or operator defined algorithms are supported, as an option. In case of supporting operator custom algorithms, optionally, the algorithm version and the operator PLMN may also be indicated. The source channel coding algorithm identification may also be represented by an AI model identification employed by source channel joint coding.

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

For network side equipment, the network side equipment receives terminal capability information sent by a terminal; and the network side equipment determines the first message according to the terminal capability information. I.e. the first message may 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 terminal capability information and a quality of service parameter requirement.

In the embodiment of the application, the wireless access network node updates the joint coding configuration of the information source channel according to the requirement of the perceived quality of service parameter (or perceived performance index). Depending on the perceived scene (e.g., object recognition, object tracking, environmental reconstruction, etc.), the transmitted perceived data may relate to one or more perceived performance indicators. A method for updating the joint coding configuration of the information source channel updates the joint coding algorithm of the information source channel or the joint coding triggering condition of the information source channel according to whether the perceived performance index meets the requirement. Source channel joint coding performance of different performance can be achieved, for example, by replacing the self-encoder (AI model) for different number of coding layers and/or iterations. The update process may be a process of sending the first message, and may be an update in a sending process of other messages.

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

Or the first message is used for indicating at least one of a target format of a second physical channel and resources corresponding to the target format of the second physical channel, wherein the second physical channel comprises at least one of a second format and a third format, 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, and 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 application, the format of the physical channel corresponds to the coding mode, and the coding mode of the target data can be correspondingly determined by indicating the format of the physical channel. It can be understood that the first message determines the uplink or downlink coding mode of the target data by indicating the format of the physical channel, or determines whether to use source channel joint coding.

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 is 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 comprises:

The terminal receives a fourth message sent by network side equipment;

The fourth message is used for indicating at least one of activating 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 for indicating at least one of activating the resource corresponding to the target format of the second physical channel and the target format of the second physical channel.

In the embodiment of the present application, after receiving at least one of the physical channel format and the format resource indicated by the first message, the terminal may further activate at least one of the physical channel format and the format resource based on the fourth message. For example, at least one of a plurality of physical channel formats and a plurality of format resources is indicated in the first message, and at least one of the plurality of items is activated using the fourth message described above.

In the embodiment of the application, the network side equipment can send a fourth message to the terminal under the condition that the second trigger condition is met, wherein the fourth message is used for indicating at least one of the resources corresponding to the first format of the first physical channel and the first format of the first physical channel to be activated, or the fourth message is used for indicating at least one of the resources corresponding to the target format of the second physical channel and the target format of the second physical channel to be activated. The network side device can firstly perform configuration of the physical channel format and/or the format resource through the first message, and then activate at least part of the configuration under the condition that the second trigger condition is met, so that the timeliness of configuration use can be improved. The setting manner of the second triggering condition is similar to that of the first triggering condition, and there may be at least one of a corresponding triggering parameter, a triggering event and a triggering threshold. For example, the parameters may be channel quality information, or parameters such as the situation of perceived data that needs to be reported by the UE, and based on whether the parameters meet the conditions, whether to send the fourth message for triggering is determined.

In the embodiment of the application, the physical channel and/or the physical channel format which support the joint coding of the information source channels can have the characteristics of high instantaneity and high efficiency. The embodiment of the application can save the protocol functions of the radio access network layer 2 and the radio access network layer 3 possibly related to the existing protocol in the data transmission process and save the protocol functions of the core network node because the physical channel transmission has the characteristic of high real-time property. Meanwhile, the source channel joint coding is oriented to specific target data, so that the data transmission quantity can be effectively reduced, and the method is more suitable for the condition of low signal-to-noise ratio and the condition of reducing data transmission overhead.

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 the embodiment of the application, the terminal determines at least one of the target coding mode and the target decoding mode of the target data according to the first message. Or, the UE receives the first message and determines whether to use source channel joint coding according to the first message. The above determination of whether to use may be that the terminal determines whether to use source channel joint coding in the uplink transmission process, or that the terminal determines whether to use source channel joint decoding in the downlink reception process. Coding modes are generally indicated according to existing protocol positioning habits. Here, in the case of downlink reception of the terminal, the target decoding method for downlink data reception of the terminal may be implicitly indicated by the target coding method for downlink data.

Optionally, the method further comprises:

The terminal sends a second message to the network equipment;

The second message includes at least one of:

target data encoded by the target encoding mode;

Indication of whether source channel joint coding is used.

In the embodiment of the present application, optionally, the terminal may determine whether to use source channel joint coding for uplink target data (e.g., perceptual data) based on the first message. After determining whether to use the source channel joint coding to send the target data, that is, after determining the target coding mode (for example, the source channel joint coding or the source channel independent coding), the terminal may directly use the target coding mode to code the target data and send the coded target data to the network side device, or may first send the indication information to instruct the network side device to indicate the target coding mode determined by the terminal, or send the indication information to instruct whether to use the source channel joint coding.

Optionally, in the case that 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 equipment;

and sending the target data to the network side equipment according to the target data reporting configuration and the target coding mode.

In the embodiment of the application, the network side equipment receives a second message sent by a terminal, wherein the second message comprises at least one item of target data coded by utilizing a target coding mode, wherein the target coding mode is a coding mode of the target data determined by the terminal according to the first message, and the indication information of whether to use source channel joint coding or not. In the case that the second message includes target data encoded by using a target encoding manner, the network side device decodes the target data according to the target encoding manner; and under the condition that the second message comprises indication information of whether to use source channel joint coding, the network side equipment sends the reporting configuration of the target data to the terminal. And the terminal can send the target data to the network side equipment according to the target data reporting configuration and the target coding mode. The above description of the target data reporting configuration refers to the description of the foregoing embodiments. It can be understood that the target data reporting configuration may be sent in the first message, or may be sent to the terminal by the network side after receiving the second message.

In the embodiment of the application, the UE sends a second message to the wireless access network node, wherein the second message comprises data which is jointly coded by the information source channels and/or indicates whether the information source channels are jointly coded. Optionally, the second message may further comprise a source channel joint coding algorithm indication for indicating which predefined algorithm or pre-deployment algorithm in the protocol is used.

Optionally, in the case that 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 comprises:

The terminal receives the third message sent by the network side equipment, wherein the third message comprises target data coded by utilizing the target coding mode;

And decoding the third message according to the decoding mode corresponding to the target encoding mode or the target decoding mode.

In the embodiment of the present application, optionally, the terminal may determine whether to use source channel joint coding for downlink target data (e.g., perceived data) based on the first message. When receiving the target data (the third message), the terminal may decode the target data based on the decoding mode corresponding to the determined target encoding mode or the target decoding mode, to obtain the data decoded by the third message.

Optionally, the method further includes that the terminal sends feedback information to the network side device, where the feedback information is used to indicate whether the data decoded by the third message meets the requirement of the quality of service parameter. For example, taking positioning accuracy as an example, if the terminal has an error of not more than 1cm with respect to horizontal accuracy and vertical accuracy, the UE determines whether the accuracy requirement is satisfied based on the positioning result generated by the received data. If the required accuracy is reached, the quality of service requirement is fed back. Otherwise, the feedback does not meet the quality of service requirement.

The terminal side can obtain the service quality parameter requirement through the application function of the terminal, or the protocol function of the terminal side can be determined according to the requirement, or the terminal can obtain the service quality parameter requirement from the access network node.

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

Example 1, PUCCH format supporting perceptual data reporting.

This embodiment illustrates the support of source channel jointly encoded perceptual data reporting via PUCCH first format. Currently, the channel coding scheme adopted is different according to the different PUCCH formats. Specifically, the repetition coding scheme is adopted by the PUCCH format 1/1a/1b, the Reed-Muller coding scheme is adopted by the PUCCH format 2/2a/2b, the Polar coding scheme is adopted by the PUCCH format 3/4/5/6, and the PUCCH format is used for independent coding of an information source channel. In the embodiment of the application, a PUCCH first format is newly added, and the PUCCH first format adopts source channel joint coding. One way of source channel joint coding may be a self-encoder based source channel joint coding method.

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

Step 1, the network side equipment sends a first message to the UE, wherein the first message is used for indicating whether the data (perceived data) in the mobile network use source channel joint coding. The present embodiment assumes that the PUCCH first format employs source channel joint coding, and thus an example of a first message is control signaling of the control plane. For example, at least one of the PUCCH first format and the PUCCH first format resource is configured by PUCCH-Config/PUCCH-ConfigCommon/PUCCH-CongfigurationList. Further, an example of the first message is that at least one of the PUCCH first format and the PUCCH first format resource is configured through DCI carried by a downlink control channel PDCCH. Further, an example of a first message is to configure a plurality of PUCCH format parameters including at least the PUCCH first format through radio resource control (Radio Resource Control, RRC), and then the radio access network node instructs to activate at least one of the PUCCH first format and the PUCCH first format resource through a medium access control unit (MEDIA ACCESS Control Control Element, MAC CE) according to channel quality information (e.g. based on channel reciprocity, the radio access node measuring channel quality according to information such as uplink signal SNR or SINR) and a perceived data condition (e.g. data size) that needs to be reported by the UE. Here, the PUCCH first format is defined by a protocol and is jointly encoded using a source channel.

Optionally, the first message comprises a source channel joint coding algorithm indication for indicating which predefined algorithm or pre-deployment algorithm in the protocol is used. For example, one algorithm is the aforementioned self-encoder based source channel joint coding, and another algorithm is the CNN-based deep learning source channel joint coding algorithm.

And step 2, the UE receives a first message, processes the perception data based on the first message, and at least comprises source channel joint coding.

And 3, the UE sends a second message to the radio access network node, wherein the second message uses the PUCCH first format.

And 4, the wireless access network node receives the second message and performs source channel joint decoding.

And 5, optionally, the wireless access network node updates the source channel joint coding configuration according to the perceived performance index (also called perceived quality of service parameter). For example, the source channel joint coding algorithm is updated based on the location accuracy of the environment reconstruction.

Example 2, a second physical channel supporting perceived data reporting

The present embodiment describes supporting data transmission inside a mobile network through a second physical channel. Compared with the LPP scheme, the scheme of the embodiment only relates to physical layer processing of a second physical channel, saves the protocol functions of the existing protocol radio access network layer 2 and layer 3 and also saves the protocol functions of a core network node. Especially for the case of perceptually assisted communication, the time slot and subframe interval of the communication are considered to be not more than millisecond, so that higher real-time performance and improved efficiency can be provided by means of the second physical channel.

In this embodiment, the second physical channel supports at least the source channel joint coding, and optionally, the second physical channel may also support two independent modules of source coding and channel coding. When the source coding and the channel coding are independent of each other, potential channel coding modes include Low-DENSITY PARITY-check (LDPC), polar, turbo, fountain, and the like, and the source coding is an optional function. If source coding is included, then see internet engineering task force series documents (INTERNET ENGINEERING TASK Force Request For Comments, IETF RFC), potentially lossless source coding is as follows:

1) DeFLATE, a widely used lossless compression algorithm, is commonly used in ZIP, GZIP and other file formats. The source coding algorithm is adopted in the existing protocol UDC;

2) LZ77/LZ78, a dictionary-based lossless compression algorithm, which is commonly used in LZW, ZIP and other file formats;

3) Brotli A lossless compression algorithm has the characteristics of high compression ratio and quick decompression, and becomes one of the standards of Web content compression;

4) Zstandard A lossless compression algorithm has the characteristics of high compression ratio and quick decompression, and becomes one of the standards of a plurality of application fields;

5) LZ4 is a lossless compression algorithm, has the characteristics of high compression speed and quick decompression, and is commonly used in scenes such as real-time data transmission, high-speed cache and the like;

6) Snappy is a lossless compression algorithm, has the characteristics of high compression speed and quick decompression, and is commonly used in scenes such as big data processing and real-time data transmission.

If the second physical channel supports both source channel joint coding and source coding and channel coding independent. Assuming that the second physical channel second format employs source channel joint coding, the second physical channel third format employs channel coding (e.g., LDPC) only. Accordingly, one configuration is to configure the second format of the second physical channel (open source channel joint coding) in the case of low SNR, and configure the third format of the second physical channel in the case of high SNR (using channel coding in which source coding and channel coding are independent).

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

Step 0, optionally, the UE sends UE capability information to the network side equipment. The capability information includes at least that the UE supports the second physical channel. When the UE supports the second physical channel, optionally, the capability information may further include at least one of a second physical channel format supported by the UE, a source channel joint coding algorithm for each second physical channel format, and a channel coding algorithm for each second physical channel format. Optionally, the capability information may further include whether the UE supports operator-defined source channel joint coding. Considering that the UE may be multi-card for different operators, the algorithm version information and the corresponding PLMN identity need to be indicated for the operator-defined source channel joint coding algorithm.

Step 1, the network side equipment sends a first message to the UE, wherein the first message is used for indicating whether the data (perceived data) in the mobile network use source channel joint coding. The present embodiment assumes that the second physical channel supports at least source channel joint coding, and thus an example of a first message is control signaling of the control plane. At least one of the second physical channel, and the second physical channel resources, is configured, for example, based on a configuration field of the physical channel in a protocol. Further, an example of a first message is that the second physical channel and/or the second physical channel resources are configured by DCI carried by a downlink control channel PDCCH. Further, an example of the first message is that a second physical channel plurality of format parameters (for example, the aforementioned second format and third format) are configured through RRC, the second physical channel plurality of formats at least includes the second physical channel second format supporting joint coding of the source channel, and then the radio access network node indicates activation of at least one of the second physical channel second format and the second physical channel second format resource according to channel quality information (for example, based on channel reciprocity, the radio access node measures channel quality according to uplink signal SNR or SINR, etc.) and perceived data conditions (for example, data size) that need to be reported by the UE through MAC CE. It should be noted that, here, the second format of the second physical channel may be defined by a protocol and use source channel joint coding.

Optionally, the first message includes a source channel joint coding algorithm indication for indicating which predefined algorithm or pre-deployment algorithm in the protocol to use, such as the algorithm described in example 1.

And 2, the UE receives the first message and processes the perception data based on the first message.

And 3, the UE sends a second message to the wireless access network node, wherein the second message uses a second physical channel configured by the first message.

And 4, the wireless access network node receives the second message and receives and processes the second physical channel process.

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 index (also referred to as perceived quality of service parameter, see explanation 1). For example, the source channel joint coding algorithm is updated based on the location accuracy of the environment reconstruction.

Example 3, condition-based perceived data reporting

The present example differs from example 1 in that the UE determines whether to use the source channel joint coding according to the perceived data collection situation based on the conditions configured at the network side.

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

Step 1, network side equipment sends a first message to UE, wherein the first message at least comprises an information source channel joint coding triggering condition. The source channel joint coding triggering condition comprises a source channel coding triggering parameter and/or a triggering event type and a corresponding threshold value. One example includes one or more of the items shown in table 2 above (each item in the table is by way of example only, where each field may have meaning options, and combinations between different fields may be other, not limited).

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

And 3, the UE transmits a second message which at least comprises information source channel joint coding or not. When the source channel is encoded, the second message may optionally further comprise a source channel joint coding algorithm.

And 4, the wireless access network node receives the second message and sends the perceived data reporting configuration according to the second message. The configuration of the perceived data reporting is mainly used for indicating the resources of the perceived data reporting, and if the PUCCH reporting is adopted, one configuration method is shown in step 1 in example 1.

And step 5, the UE receives the perceived data reporting configuration and transmits the perceived data jointly coded by the information source channels.

And step 6, the wireless access network node receives the perception data and performs joint decoding of the information source channels.

Step 7, optionally, the wireless access network node updates the information source channel joint coding triggering condition configuration according to the perception performance index (also called as perception service quality parameter, see explanation 1).

Example 4, a method for a UE to receive target data

The present embodiment describes a method for receiving a perceived number by a UE through a downlink channel. The method is also suitable for the situations of high real-time requirements, large data volume or low SINR of the type of the AI model and the like received by the UE. The downlink channel may be a PDSCH channel or a newly added first downlink physical channel. The PDSCH is required to support the source channel joint coding in an expanding way based on the existing channel coding mode, or the newly added first downlink physical channel supports the source channel joint coding.

The following is a brief description of the UE and network side device interaction flow in example 4:

Step 1, the network side equipment sends a first message to the UE, wherein the first message is used for indicating whether the data (perceived data) in the mobile network use source channel joint coding. The present embodiment assumes that one option supported by PDSCH is source channel joint coding, so an example of a first message may be downlink control information DCI configured to indicate that the PDSCH is source channel joint coding.

And step 2, the UE receives a first message, processes the perception data based on the first message, and at least comprises source channel joint decoding.

And 3, the UE transmits the source channel joint decoding feedback information to the radio access network node. The source channel joint decoding feedback information is used for indicating whether the received perception data meets the requirement of the required perception performance index (the requirement of the service quality parameter).

And 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 parameters of the source channel joint coding or modifying algorithms of the source channel joint coding.

In the embodiment of the application, a terminal receives a first message sent by network side equipment, and the terminal determines at least one of a target coding mode and a target decoding mode of target data according to the first message, wherein the first message is used for indicating at least one of whether the target data uses source channel joint coding or not and whether the target data uses a first triggering condition of the source channel joint coding or not. In the embodiment of the application, the terminal can determine whether to use the source channel joint coding for data transmission based on the first message, so that the diversity of data transmission coding modes can be enriched, and the transmission efficiency of target data is further improved.
