The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

I. Source and channel coding/decoding methods in wireless communication systems

In wireless communication systems, source coding and channel coding of the information to be transmitted can be performed independently. For example, the information to be transmitted may first undergo source processing through source coding, such as source compression. Then, considering the complexity and interference issues of wireless channel transmission, the source information may be further processed through channel coding to achieve effective transmission.

II. On Joint Coding/Decoding of Source and Channel

Basic source coding and channel coding are two independent information processing schemes and stages. However, these two types of schemes and stages can also be considered and designed in a unified manner to form a joint source-channel coding/decoding processing scheme. However, such a design requires comprehensive consideration of source information, channel information, and matching algorithms to be successful. Traditional wireless communication system designs have not introduced or considered the aforementioned joint source-channel coding/decoding scheme.

III. Channel State Information Acquisition and Indication Methods

Channel state information (CSI) is crucial in both LTE and NR systems, determining the performance of Multiple Input Multiple Output (MIMO) transmissions. Generally, CSI indications in a communication system can include indications of information such as Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and Rank Indication (RI). The base station first configures the indication parameters for CSI indication; for example, the UE may need to indicate CQI, PMI, and RI. What information is included in the data? The base station also configures some reference signals for CSI measurement. The UE determines the current channel state information by measuring the reference signals. The UE also indicates the determined channel state information to the base station, so that the base station can configure a reasonable and efficient data transmission method based on the current channel conditions.

In the above process, the UE needs to perform two encoding-related operations on the Channel State Information (CSI). The first encoding encodes the raw channel information (CSI measurement results) to obtain encoded channel information. The main purpose here is to compress the information to be transmitted as much as possible (compressed CSI generation) to reduce air interface overhead while ensuring transmission quality. The second encoding performs channel coding on the information to be transmitted (channel-coded CSI), so that the information to be transmitted can be better received and recognized by the network side, for example, through polar coding or low-density parity check (LDPC) coding. After receiving the CSI feedback, the network side, such as the base station, can perform channel decoding of CSI and restore CSI utilization. The basic flowchart is shown in Figure 2.

IV. Basic Information on Artificial Intelligence

In recent years, artificial intelligence research, represented by neural networks, has achieved remarkable results in many fields, and it will play an important role in people's production and life for a long time to come.

A simple neural network's basic structure includes an input layer, hidden layers, and an output layer, as shown in Figure 3. The input layer receives data, the hidden layers process the data, and the final result is generated in the output layer. Each node represents a processing unit, which can be considered as simulating a neuron. Multiple neurons form a layer of the neural network, and the information transmission and processing across multiple layers construct a complete neural network.

With the continuous development of neural network research, deep learning algorithms for neural networks have been proposed in recent years, introducing more hidden layers. By training neural networks with multiple hidden layers layer by layer for feature learning, the learning and processing capabilities of neural networks have been greatly improved, and they have been widely used in pattern recognition, signal processing, optimization and combinatorial processing, and anomaly detection.

V. Using Neural Networks for Channel State Information Indication

Figure 4 shows a basic network architecture for channel state information indication using a neural network model. First, the encoder compresses the raw channel information (e.g., CSI) using an encoding model (e.g., a neural network) to generate channel state indication information, which is then used for channel state information indication. The decoder then uses the channel state indication information to reconstruct the feedback channel information using a decoding model (e.g., a neural network).

Independent CSI compression coding (and recovery decoding) cascaded with independent CSI channel coding (and channel decoding) can further optimize the process. Previous research on AI/ML-based CSI compression and recovery mainly focused on the compression and recovery of CSI itself. The compressed CSI result is still part of UCI or PUSCH and still needs to be transmitted between the UE and the network using traditional channel coding. However, for CSI transmission, it is only necessary to clearly define what information is to be transmitted and how many bits are actually transmitted over the air interface. The manual segmentation of how many bits to compress first (e.g., source coding, CSI compression coding) and then how many bits to expand through channel coding (e.g., channel coding) can be avoided. On the one hand, this simplifies the CSI coding (and decoding) scheme; on the other hand, it avoids manual information segmentation. Adopting an adaptive coding scheme that balances information compression and channel coding capabilities, obtained through AI/ML training, such as a decoding scheme that adaptively balances information recovery and channel decoding capabilities, is beneficial for achieving better CSI coding (and decoding) results.

If a combined CSI compression coding and channel coding scheme is used at the transmitting end, a corresponding combined CSI recovery decoding and channel decoding scheme must also be used at the receiving end to ensure normal CSI transmission and parsing. The embodiments of this application can provide corresponding indications and mechanisms for determining the CSI compression coding and channel coding schemes, thereby ensuring the aforementioned transmit-receive consistency.

Furthermore, compression coding and channel coding for the CSI problem are applicable cases for joint source-channel coding. Besides the CSI problem, embodiments of this application can also be applied to the indication and determination of joint source-channel coding schemes for problems such as measurement reporting, sensing reporting, and transmission feedback reporting.

Joint coding of source compression coding and channel decoding based on AI/ML may not be supported by all UEs and requires corresponding capabilities. Similarly, joint decoding of source recovery decoding and channel decoding based on AI/ML may not be supported by all network-side devices and also requires corresponding capabilities.

Figure 5 is a schematic flowchart of a communication method 500 according to an embodiment of this application. This method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes at least a portion of the following:

S510, The first device determines the first encoding method through the first information;

S520, The first device encodes the second information using the first encoding method.

In this embodiment, the first device may be a terminal device, and the first information may be used to instruct the first device to use a first encoding method, such as a joint encoding method. After obtaining the first information, the first device may perform joint encoding on the second information to be transmitted, such as source-channel joint encoding, based on the first encoding method.

In one implementation, the first information may be predefined in the protocol or may come from a second device, such as a network device.

In one implementation, the first information includes at least one of the following: the configuration corresponding to the first encoding method, the configuration identifier (ID) corresponding to the first encoding method, the scheme corresponding to the first encoding method, the scheme ID corresponding to the first encoding method, the model corresponding to the first encoding method, the model ID corresponding to the first encoding method, the dataset corresponding to the first encoding method, and the first encoding... The dataset ID corresponding to the coding method.

For example, if the first device obtains the configuration ID corresponding to the first encoding method, it can determine the configuration corresponding to the first encoding method based on the configuration ID. If the first device obtains the model ID corresponding to the first encoding method, it can determine the model corresponding to the first encoding method based on the model ID. If the first device obtains the scheme ID corresponding to the first encoding method, it can determine the scheme corresponding to the first encoding method based on the scheme ID. If the first device obtains the dataset ID corresponding to the first encoding method, it can determine the dataset corresponding to the first encoding method based on the dataset ID. This dataset can be used to train the model corresponding to the first encoding method.

In one implementation, the first information is at least one of the following: control channel configuration format, UCI configuration, Radio Resource Control (RRC) configuration, reference signal configuration, transmission resource configuration, measurement configuration, and measurement reporting configuration.

In this embodiment, the control channel configuration format, such as the PUCCH format, sent by the second device to the first device may include indicator bits related to the first coding scheme. These indicator bits can indicate first information. For example, one or more indicator bits in the PUCCH format indicate the scheme ID corresponding to the first coding scheme, and another one or more indicator bits indicate the model ID corresponding to the first coding scheme. After receiving the control channel configuration format, the first device can determine the first coding scheme based on the first information in the control channel configuration format.

In this embodiment of the application, the sending of UCI configuration, RRC configuration, reference signal configuration, transmission resource configuration, measurement configuration, or measurement reporting configuration by the second device to the first device may include first information. After receiving any of the above configurations, the first device can determine a first encoding method based on the first information in the received configuration.

In one implementation, the first information is in an RRC message. For example, the RRC message carries configuration information indicating the first encoding method, indicating at least one of the following: configuration, configuration ID, scheme, scheme ID, model, model ID, dataset, and dataset ID corresponding to the first encoding method.

In one implementation, the RRC message indicates that the first information includes at least one of the following:

This first information is indicated in the RRC message that configures one or a set of measurement configurations;

This first information is indicated in the RRC message configured for one or a group of measurement reports.

For example, when configuring UCI (such as UCI for CSI feedback) via an RRC message, the RRC message indicates a first encoding method, such as at least one of encoding configuration, encoding configuration ID, encoding function ID, and encoding model ID.

For example, when pre-configuring one or a group of transport resources (e.g., PUCCH resources) via an RRC message, the RRC message indicates the first encoding method.

For example, the first encoding method can be indicated when configuring a CSI resource via an RRC message, or when configuring a CSI resource set.

For example, when configuring one or a group of reference signals (such as CSI-RS, DMRS, SSB, etc.) via an RRC message, the RRC message indicates the first encoding method. This first encoding method is used when reporting measurements of the configured reference signals.

For example, when configuring one or a group of measurement configurations (such as beam measurement or cell measurement) via an RRC message, the RRC message indicates the first encoding method. The measurement results can be processed using the first encoding method.

For example, when configuring one or a group of measurement reports (such as beam measurement reports or cell measurement reports) through an RRC message, the RRC message indicates a first encoding method, such as processing the measurement results and measurement reports through the first encoding method.

In one embodiment, the second information includes at least one of the following: channel information, reference signal information, measurement information, sensing information, transmission performance feedback information, and data to be transmitted.

For example, in the measurement reporting configuration of an RRC message sent by a second device to a first device, the first device is instructed to use a first encoding method to process and/or report the measurement results. Similarly, when triggered by a DCI or MAC CE, the DCI or MAC CE may instruct the use of the first encoding method to process and/or report the measurement results. Furthermore, in the reference signal configuration of an RRC message, the first encoding method may be used to process and/or report the measurement results of the reference signal.

In one implementation, the encoding method of the second information includes:

Different types of second information are processed using either the first encoding method or non-first encoding methods;

Different first encoding methods are used to process different types of second information.

In this embodiment, the encoding method of the second information can be the first encoding method, such as the source-channel joint encoding method, or a non-first encoding method, such as the channel encoding method. If the first device determines the first encoding method based on the first information, then the first encoding method is used to process the second information.

In the embodiments of this application, the second information includes various types. Different types of second information may employ different first encoding methods. For example, CSI may be processed using first encoding methods such as CSI compression model or CSI prediction model.

In one implementation, the second information processed by the first encoding method is no longer subjected to channel encoding or decoding.

In one implementation, the first encoding method includes: performing source-channel joint encoding on the second information using the first encoding method. For example, the information after performing source-channel joint encoding on the second information using the first encoding method does not require further channel encoding or decoding.

In one implementation, the first encoding method includes: compressing the second information using one or more first encoding methods, and/or channel coding the second information using one or more first encoding methods. For example, compression and/or channel coding of the second information can be accomplished using one or more AI/ML models.

In one embodiment, the first encoding method further includes modulating the encoded information. For example, after performing source-channel joint encoding on the second information using the first encoding method, the jointly encoded information can be modulated.

In one implementation, the first information is used to indicate a first decoding method, which corresponds to the first encoding method. For example, when a second device uses the first decoding method for decoding, the second device can indicate the first decoding method to the first device through the first information. The first device can determine the corresponding first encoding method based on the first decoding method. Then, the first device can encode the second information using the first encoding method.

In one implementation, the information processed by the first decoding method is no longer subject to channel coding or decoding.

In one embodiment, the first decoding method includes: performing source-channel joint decoding on the information to be decoded using the first decoding method. For example, a first device performs source-channel joint encoding on the second information using a first encoding method, and sends the jointly encoded information to a second device. The second device can then decode the received jointly encoded information using a first decoding method corresponding to the first encoding method.

In one embodiment, the first decoding method includes decoding the information to be decoded using one or more first decoding methods, and/or performing channel decoding on the information to be decoded using one or more first decoding methods, such as decompression and recovery.

To address the problems in communication systems and the additional information and constraints that need to be considered, the communication method in this application embodiment may include a method for determining the AI encoding and/or decoding scheme of the source channel. For example, this method may be implemented based on a new Physical Uplink Control Channel (PUCCH) format, as well as other configuration and/or indication methods. In this method: the UE determines a first encoding method through first information, thereby matching it with the decoding method on the network side. The method of determining the first encoding method based on the first information includes: indicating the first encoding method through the first information in one or more of the following methods: control channel configuration format (e.g., PUCCH format), UCI configuration, RRC configuration, reference signal configuration, transmission resource configuration, measurement configuration, measurement reporting configuration, etc. Different implementation methods are given in this method, particularly a design scheme for the new PUCCH format for UCI. Additionally, the network may also configure multiple channel configuration formats and further indicate the channel configuration format used in real time, or the UE may indicate the channel configuration format used directly/indirectly. This method can be applied to the processing and indication of information to be transmitted, such as channel information, measurement information, sensing information, and transmission performance feedback information, using the first encoding method.

Example 1:

1. Basic Description:

The first device determines the first encoding method based on the first information, for example:

The first device can be a terminal device.

First information: Used to determine the first encoding method. For example, the configuration or configuration ID corresponding to the first encoding method, or the scheme or scheme ID corresponding to the first encoding method, or the model or model ID corresponding to the first encoding method, or the dataset or dataset ID corresponding to the first encoding method.

The method of determining the first encoding method through the first information includes: indicating the first encoding method through the first information in one or more of the following methods: control channel configuration format (e.g., PUCCH format), UCI configuration, RRC configuration, reference signal configuration, transmission resource configuration, measurement configuration, measurement reporting configuration, etc. The method of determining the first encoding method through the first information also includes: predefining one or more first encoding methods in the protocol.

Specifically, it includes one or more of the following options:

Option 1: Adopt a new control channel configuration format (e.g., PUCCH format).

For example, the control channel configuration format (e.g., PUCCH format) includes indication information for the first encoding method.

For example, the PUCCH format defines specific information to indicate the first encoding method. For instance, the PUCCH format defines N bits of information to indicate the first encoding method. For example, N bits can indicate the configuration, scheme, model, dataset, or ID information corresponding to the configuration/scheme/model/dataset corresponding to the first encoding method.

For example, when configuring a control channel (e.g., PUCCH), a base station can indicate the first encoding method in the indication information (e.g., on specific indication bits) corresponding to the control channel configuration format (e.g., PUCCH format). For instance, the base station can indicate the ID of the first encoding method through N bits in the PUCCH, such as indicating the PUCCH encoding configuration, encoding configuration ID, encoding function ID, or encoding model ID, as shown in Figure 12.

Option 2: The RRC message indicates the first encoding method. For example, it indicates the configuration information of the first encoding method, such as: encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID, dataset, and dataset ID.

For example, the RRC message indicates the first encoding method corresponding to the UCI.

For example, an RRC message indicates at least one of the following: the encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID, etc., corresponding to the UCI.

For example, when configuring UCI (such as UCI for CSI feedback) via an RRC message, the RRC message indicates the first encoding method (e.g., encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID).

For example, when pre-configuring one or a set of transport resources (e.g., PUCCH resources) via an RRC message, the RRC message indicates a first encoding method (e.g., encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID).

For example, when configuring a CSI resource via an RRC message, the first encoding method is indicated, such as when configuring a CSI resource set.

For example, when configuring one or a group of reference signals (e.g., CSI-RS, DMRS, SSB, etc.) via an RRC message, the RRC message indicates the first encoding method (e.g., encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function). ID, encoding model, encoding model ID). The first encoding method is used when reporting measurements on the configured reference signal.

For example, when configuring one or a set of measurement configurations (e.g., beam measurement, cell measurement) via an RRC message, the RRC message indicates a first encoding method (e.g., encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID, for example, processing the measurement results using the first encoding method).

For example, when configuring one or a group of measurement reports (e.g., beam measurement reporting, cell measurement reporting) via RRC messages, the RRC message indicates the first encoding method (e.g., encoding configuration, encoding configuration ID, encoding scheme, encoding scheme ID, encoding function, encoding function ID, encoding model, encoding model ID, for example, processing measurement results and measurement reports using the first encoding method). As shown in Figure 13.

The first encoding method includes: a method for encoding or processing the second information, which may be: a method for encoding or processing channel information, a method for encoding or processing measurement results, a method for encoding or processing sensing information, a method for encoding or processing transmission status feedback information, a method for encoding or processing data to be transmitted, etc., one or more of these.

The encoding object of the first encoding method includes: second information, which may be channel information, reference signal information, measurement information, sensing information, transmission status feedback information, data to be transmitted, etc., one or more of these.

Features of the first encoding method: The features of the first encoding method may include one or more of the following:

For example: (0) For the same content to be transmitted, there can be different encoding methods. For example, there is a distinction between the first encoding method and the non-first encoding method, as well as different first encoding methods.

For example: (1) The characteristic of the first coding method is that the second information after the first coding method is no longer channel-coded.

For example: (2) The characteristic of the first encoding method is that the second information after the first encoding method is no longer decoded by the channel.

For example: (3) Jointly encode the second information by the first encoding method (e.g., AI/ML model) (considering channel characteristics), such as source-channel joint encoding.

For example: (4) compressing the second information using a first encoding method (e.g., an AI/ML model), and/or channel coding the second information using a first encoding method (e.g., based on an AI/ML model). The first encoding method can complete the above compression of the second information and/or channel coding of the second information using one processing scheme (e.g., one AI/ML model) or multiple processing schemes (e.g., two or more AI/ML models).

For example: (5) The first encoding method may also include the first modulation, such as AI-based modulation.

In addition, the encoding method can be determined by indicating the decoding method:

1. The above-mentioned indication of the first encoding method can also be accomplished through the indication of the first decoding method, where the first decoding method is the decoding method corresponding to the first encoding method, such as joint decoding. For example, the first decoding method can be indicated by (e.g., decoding configuration, decoding configuration ID, decoding scheme, decoding scheme ID, decoding function, decoding function ID, decoding model, decoding model ID).

The first decoding feature can be one or more of the following features:

For example: (1) The first decoding method is characterized by the fact that channel coding is not required.

For example: (2) The characteristic of the first decoding method is that channel decoding is not required.

For example: (3) The characteristic of the first decoding method is to perform joint decoding of the information to be decoded by the first decoding method (e.g., AI/ML model), such as (considering channel characteristics) source-channel joint decoding.

For example: (4) The first decoding method is characterized by decoding the information to be decoded through the first decoding method (e.g., an AI/ML model) and/or performing channel decoding on the information to be decoded through the first decoding method (e.g., based on an AI/ML model). The first decoding method can complete the above-mentioned decoding of the information to be decoded and/or channel decoding of the information to be decoded through one processing scheme (e.g., one AI/ML model) or multiple processing schemes (e.g., two or more AI/ML models).

For example: (5) The first decoding method may also include the first demodulation, such as AI-based demodulation.

2. The second device instructs the first device to send the first information. The first device can be a UE, and the second device can be a network device.

Extension 1:

1. RRC can be configured with multiple channel configuration formats (e.g., configuration formats for data channels, control channels, and AI-related transmission channels). For example, RRC can be configured with a first channel configuration format and a second channel configuration format; the first channel configuration format uses a first encoding method, while the second channel configuration format does not use the first encoding method.

A concrete example is: RRC is configured with multiple control channel configuration formats (e.g., PUCCH format). For instance, RRC is configured with a first control channel configuration format (e.g., PUCCH format 1) and a second control channel configuration format (e.g., PUCCH format 2). The first control channel configuration format is characterized by indicating the use of a first coding method, while the second control channel configuration format is characterized by not using the first coding method. For example, the first control channel configuration format is the PUCCH configuration format required for AI-based CSI feedback, while the second control channel configuration format is the PUCCH configuration format required for non-AI CSI feedback.

2. The network can indicate the channel configuration format currently used by the UE (e.g., the current control channel configuration format, PUCCH format, etc.). The current data channel configuration format, etc., for example, indicating which channel configuration format is used in the DCI.

3. The UE can determine whether to use the first channel configuration format or the second channel configuration format for transmission. The UE can indicate or determine the channel configuration format to be used (e.g., the currently used control channel configuration format, PUCCH format, the currently used data channel configuration format, etc.) through different scrambling codes, DMRS sequences, indications in the UCI, or N-bit indications.

Extension 2:

1. Methods for determining the first coding scheme based on channel information, measurement information, sensing information, and transmission performance feedback information (e.g., ACK/NACK information) include:

The transmission content processed by the first encoding method can also be: channel information, measurement results, sensing information, transmission performance feedback information (such as ACK/NACK information), and corresponding information after preprocessing of the above information.

The measurement reporting configuration specifies the use of the first encoding method, for example, using the first encoding method to process and report measurement results. For instance, when configuring measurement reporting in an RRC message, the first encoding method is specified for processing and reporting measurement results.

In the triggering of measurement reporting, the instruction indicates the use of the first coding method, such as using the first coding method to process and report the measurement results. For example, when triggered by DCI or MAC CE, the instruction in DCI or MAC CE indicates the use of the first coding method to process and report the measurement results.

In the reference signal configuration, the first encoding method is indicated, for example, the measurement results of the reference signal are processed and reported using the first encoding method. For instance, when configuring the reference signal in an RRC message, the first encoding method is indicated for processing and reporting the measurement results of the reference signal.

The aforementioned channel information, measurement information, sensing information, and transmission performance feedback information (such as ACK/NACK information) can be from a single channel or multiple channels, from a single cell or multiple cells, from a single beam or multiple beams, from a single target or multiple targets, from a single carrier or multiple carriers, or from a single process or multiple processes.

2. The above configuration can be different for each user and is UE-specific.

Extension 3:

1. The base station configures a first encoding method for the UE. For example, the base station configures one or more of the following for the UE: algorithm, model format, model, data format, and data, to complete the first encoding method. The configuration can be done by the base station instructing the UE to specify the model format ID, model ID, data format ID, and data ID of the first encoding method.

2. The base station transmits the first encoding method to the UE. For example, the base station transmits one or more of the algorithms, models, and data used to complete the first encoding method to the UE.

3. The base station may configure or transmit multiple first encoding methods to the UE. For example, the base station may configure or transmit one or more of the following algorithms, model formats, models, data formats, and data used to implement the first encoding method to the UE.

The UE tells the base station whether it supports the first encoding method capability.

This solution provides a method for determining the source channel AI encoding and/or decoding scheme, including a new PUCCH format and other configuration and indication methods. When considering the new PUCCH and/or PUSCH encoding scheme, especially after considering joint encoding of the source channel, the network side can indicate the UE's encoding scheme, thereby ensuring that the UE's encoding scheme matches the network side's decoding scheme. Specifically, for different use case characteristics and potential usage scenarios, this solution provides a new PUCCH format, which adds indication information for UCI encoding. In addition, this solution also provides other methods, such as RRC configuration, to indicate the first encoding scheme based on different channels, use cases, and characteristics of the target data to be transmitted.
