[0003] The present application belongs to the field of coding and decoding technology, and specifically relates to a method, device and communication equipment for processing channel information. Background Art

[0004] In related technologies, time-frequency and spatial compression requires encoding or decoding in conjunction with channel information from past moments, for example, by combining the intermediate state information output by the encoder or decoder at past moments. However, due to the complexity and variability of wireless channel environments, encoders or decoders may encounter issues, such as problems with their input or output information or inference process.

[0113] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first given.

[0114] (1) Artificial Intelligence (AI);

[0115] AI is currently widely used in various fields. Integrating artificial intelligence into wireless communication networks to significantly improve technical indicators such as throughput, latency, and user capacity is a key task for future wireless communication networks. AI modules can be implemented in a variety of ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses neural networks as an example, but does not limit the specific type of AI module.

[0116] A neural network diagram is shown in Figure 2, which includes an input layer, a hidden layer, and an output layer. A neural network is composed of neurons, and a neuron diagram is shown in Figure 3. K w K +b,a1,a2,…a Kis the input, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include the sigmoid function, the tanh function, and the rectified linear unit (ReLU).

[0117] Neural network parameters are optimized using a gradient optimization algorithm. Gradient optimization algorithms are a class of algorithms that minimize or maximize an objective function (sometimes called a loss function), which is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, a neural network model f(.) is constructed. With this model, the predicted output f(x) can be obtained based on the input x, and the difference between the predicted value and the true value (f(x) - Y) can be calculated. This is the loss function. The goal is to find the appropriate W and b to minimize the value of this loss function. The smaller the loss value, the closer the model is to the true value.

[0118] Currently, most common optimization algorithms are based on the back propagation (BP) algorithm. The basic idea of ​​the BP algorithm is that the learning process consists of two steps: forward propagation of signals and back propagation of errors. During forward propagation, input samples are passed from the input layer, processed layer by layer through each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, the error begins back propagation. Back propagation involves propagating the output error back through the hidden layers to the input layer layer by layer in some form, distributing the error to all units in each layer. This error signal is then generated for each unit in each layer, which serves as the basis for adjusting the weights of each unit. This process of adjusting the weights of each layer, through forward propagation of signals and back propagation of errors, is repeated over and over again. This process of continuous weight adjustment is the network's learning and training process. This process continues until the error in the network output is reduced to an acceptable level, or until a pre-set number of learning cycles is reached.

[0119] Common optimization algorithms include Gradient Descent, Stochastic Gradient Descent (SGD), Mini-batch Gradient Descent, Momentum Gradient Descent, Stochastic Gradient Descent with momentum, Adaptive Gradient Descent, Adadelta, Root Mean Square prop (RMSprop), and Adaptive Moment Estimation.

[0120] When these optimization algorithms backpropagate errors, they all calculate the derivative / partial derivative of the current neuron based on the error / loss obtained by the loss function, add the influence of the learning rate, the previous gradient / derivative / partial derivative, etc., obtain the gradient, and pass the gradient to the previous layer.

Optionally, the specific data set includes the input or output of the AI ​​unit / AI model.

[0123] Optionally, the identifier of the AI ​​unit / AI model may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, or an identifier of a specific data set associated with the AI ​​unit / AI model, or an identifier of a specific scenario, environment, channel feature, or device related to the AI / ML, or an identifier of a function, feature, capability, or module related to the AI / ML. This application does not specifically limit this.

[0124] (3) Training collaboration types for AI / ML Channel State Information (CSI) compression models;

[0125] The CSI compression use case is a typical two-end model use case, meaning the complete CSI compression model needs to be deployed on different network nodes. Currently, most considerations involve deploying the encoder on the UE and the decoder on the network (NW). The (sub-)models deployed on multiple nodes must be paired to function properly. Considering the aforementioned characteristics of the two-end model, 3GPP has identified several basic types of training collaboration:

[0126] 1) Joint training at single entity (also called type 1);

[0127] This training framework refers to training a complete encoder and decoder model on a network node (UE or NW or a third-party server node, etc.), and then deploying the corresponding model module to the target node through methods such as model transfer (for example, transferring the encoder part to the UE and the decoder part to the NW).

[0128] 2) Joint training at multiple entities (also known as type 2);

[0129] This training framework involves multiple nodes participating in the training process, with each node independently calculating the forward and backpropagation information required for local model training and updating its own model parameters. Because the training process requires forward and backpropagation of the entire model (including the encoder and decoder), the corresponding forward and backpropagation information must be transferred between participating nodes. After training is complete, the model no longer needs to be transferred between nodes.

[0130] 3) Separate training on multiple nodes (also called type 3);

[0131] This training framework involves first training a reference model on a specific node, then sending information about the reference model to the target node. The target node then uses this information to train the model it needs, ensuring that the node (sub-)models can be paired with each other. For example, the NW first trains a complete encoder-decoder model and determines that the resulting decoder is the one that will actually be used. The NW then sends information about the corresponding encoder (typically the encoder's input and output data) to the UE, which then trains its own encoder based on this information. This training framework can be further divided into two scenarios: UE-first training and NW-first training. UE-first training involves first training a complete model on the UE side, then sending the information needed for the NW to train the matching model (typically the input and output data of the model to be trained on the NW side). In contrast, NW-first training involves first training a complete model on the NW side, then sending the information needed for the UE to train the matching model (typically the input and output data of the model to be trained on the UE side).

[0132] The following describes in detail the channel information processing method provided by the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0133] As shown in FIG4 , an embodiment of the present application provides a method for processing channel information, including:

[0134] Step 401: When it is determined that a problem event occurs in the time-frequency-spatial domain compression process of channel information at a first moment, the first device performs a first operation;

[0135] Optionally, the first moment mentioned above may include any moment.

[0136] Optionally, the first device includes a terminal or a network side device.

[0137] Optionally, the first device includes at least one encoder (Encoder, ENC).

[0138] Optionally, at least one encoder in the first device corresponds to at least one AI model, for example, one encoder corresponds to one AI model, or multiple encoders correspond to one AI model. The encoder performs compression processing based on the corresponding AI model.

[0139] Optionally, the above-mentioned channel information includes channel information of CSI. Of course, the channel information may also include channel information of positioning information, etc., which is not specifically limited in the embodiments of the present application.

[0140] The above-mentioned time-frequency and spatial domain compression process refers to a compression process using a time-frequency and spatial domain compression method. In this time-frequency and spatial domain compression method, the channel information of the target time moments other than the initial time moment is combined with the intermediate state information output by the encoder corresponding to the previous time moment of the target time moment to encode the channel information of the target time moment. Optionally, the encoder at the initial time moment has no previous intermediate state information to use; or, the encoder at the initial time moment uses channel time domain related information obtained by other means as intermediate state information, such as obtaining channel time domain related information through channel statistical information and inputting it into the encoder at the initial time moment. Specifically, the first encoder that encodes the channel information at the initial time moment outputs the intermediate state information to the second encoder, and the second encoder uses the intermediate state information to encode the channel information of the first target time moment. Optionally, the second encoder also outputs the intermediate state information to a third encoder, and the third encoder is used to encode the channel information of the second target time moment based on the intermediate state information. The first target time moment is located after the initial time moment, and the second target time moment is located after the first target time moment.

[0141] Assuming that the above channel information is CSI, the time-frequency-spatial domain compression method is described below with reference to FIG5 .

[0142] As shown in Figure 5, during the time-frequency-space compression process, the channel information of the CSI of time slot X is encoded by the ENC to generate CSI reporting information. After the second device receives the CSI reporting information, it is decoded by the decoder (DEC) X to recover the channel information of the CSI of time slot X, that is, the CSI of time slot X is obtained. ’ Channel information of X, where X is 0, 1, 2, or 3. ENC1, ENC2, and ENC3 all need to use the intermediate state information output by the previous encoder when encoding the channel information of the CSI of the corresponding time slot.

[0143] The processing of the decoder is similar to that of the encoder and will not be described in detail here.

[0144] It should be noted that the intermediate state information of encoders is generally only transmitted between encoders, and the intermediate state information of decoders is generally only transmitted between decoders.

[0145] The first operation in step 401 includes at least one of the following:

[0146] Item 1: Sending first indication information, where the first indication information is used to indicate a first compression method corresponding to the channel reporting information. The first compression method is a compression method other than the time-frequency-spatial domain compression method. The channel reporting information is obtained by encoding the channel information at the first moment using the first compression method.

[0147] Exemplarily, the first compression method includes a space-frequency domain compression method. Optionally, the space-frequency domain compression method includes an AI / ML-based space-frequency domain compression method.

[0148] Exemplarily, the first compression method includes a method of compressing using a traditional codebook. Optionally, the traditional codebook includes a non-AI codebook, for example, a Type I codebook, a Type II codebook, and an enhanced Type II codebook.

[0149] After receiving the first indication information, the second device uses a compression method other than the time-frequency and spatial domains to perform decoding based on the first indication information, such as using a traditional codebook for decoding, thereby obtaining the restored channel information at the first moment, thereby ensuring the normal progress of the channel information compression process.

[0150] Item 2: reporting first channel reporting information, where the first channel reporting information is obtained by encoding the channel information at the first moment using the first compression method.

[0151] Optionally, the first channel reporting information is reported to the second device.

[0152] In an embodiment of the present application, the above-mentioned first indication information can be sent at the same time as reporting the first channel reporting information, so that the second device can decode the first channel reporting information based on the first indication information using a compression method other than the time-frequency and spatial domains, or, after receiving the first channel reporting information, the second device can decode the first channel reporting information based on the protocol agreement using a compression method other than the time-frequency and spatial domains, thereby obtaining the restored channel information at the first moment, thereby ensuring the normal progress of the channel information compression process.

[0153] Item 3: Not reporting the second channel reporting information, where the second channel reporting information is obtained by encoding the channel information at the first moment using a time-frequency-space domain compression method.

[0154] Since a problem occurs in the time-frequency-space domain compression process of the channel information at the first moment, the second channel reporting information is not reported to avoid the second device from decoding the abnormal channel reporting information.

[0155] Item 4: Sending second indication information, where the second indication information is used to indicate relevant information of the problem event.

[0156] Optionally, second indication information is sent to the second device.

[0157] Optionally, the second indication information includes at least one of the following:

[0158] Type of the problem event; illustratively, different event types correspond to different event identifiers, and the type of the problem event can be indicated by the event identifier;

[0159] Signal quality of channel information;

[0160] The timestamp corresponding to the problem event enables the second device to know the time when the problem event occurs.

[0161] Resources corresponding to the channel information; for example, the number of reference signal resources corresponding to the problematic channel information, or the resource location

[0162] Reference signal identifier corresponding to the channel information.

[0163] Here, by sending the second indication information, the second device can obtain relevant information of the problem event, and then take corresponding actions according to the information to ensure the normal progress of the channel information compression process.

[0164] Item 5: Using intermediate state information corresponding to the channel information at the second moment to encode the channel information at the third moment, wherein the second moment is a moment before the first moment, and the third moment is a moment after the first moment.

[0165] Since there is no problem in the time-frequency-spatial domain compression process of the channel information at the second moment, the intermediate state information corresponding to the channel information at the second moment can still be used to encode the channel information at the third moment, that is, the time-frequency-spatial domain coding method is still used to encode the channel information at the third moment.

[0166] Correspondingly, the decoder uses the intermediate state information corresponding to the channel reporting information at the second moment to decode the channel reporting information at the third moment, that is, the decoder continues to use the intermediate state information corresponding to the channel reporting information at the second moment, or the intermediate state information corresponding to the channel reporting information at the second moment is still used for decoding the channel reporting information at future moments.

[0167] Item 6: Do not use the intermediate state information corresponding to the channel information at the first moment to encode the channel information at the third moment.

[0168] Since a problem occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, there may be a problem with the intermediate state information corresponding to the channel information at the first moment. Here, the intermediate state information corresponding to the channel information at the first moment is not used to encode the channel information at subsequent moments, which is beneficial to improving the compression performance of the channel information at subsequent moments.

[0169] Correspondingly, the decoder does not use the intermediate state information corresponding to the channel reporting information at the first moment to decode the channel reporting information at the third moment, that is, the intermediate state information corresponding to the channel reporting information at the first moment cannot be used for decoding the channel reporting information at the next moment.

[0170] Item 7: Clear the intermediate state information corresponding to the channel information at at least one moment.

[0171] Optionally, clearing the intermediate state information corresponding to the channel information at at least one moment includes clearing the intermediate state information corresponding to the channel information at the first moment.

[0172] Here, because a problem occurs during the time-frequency-spatial domain compression process of the channel information at the first moment, the intermediate state information corresponding to the channel information at the first moment may have a problem. The intermediate state information corresponding to the channel information at the first moment is cleared to avoid encoding using the intermediate state information corresponding to the channel information at the first moment at subsequent moments. Optionally, the encoder only stores and continuously updates one copy of the intermediate state information. In this case, clearing the intermediate state information corresponding to the channel information at the first moment is equivalent to clearing the only copy of the intermediate state information stored by the encoder.

[0173] Optionally, in one embodiment, clearing the intermediate state information corresponding to the channel information at at least one moment includes clearing all the intermediate state information of the encoder.

[0174] Optionally, the decoder may clear the channel reporting information at at least one time point. For example, the decoder may clear the intermediate state information corresponding to the channel reporting information at the first time point, or may not clear the intermediate state information corresponding to the channel reporting information at the first time point. For another example, the decoder may clear all intermediate state information.

[0175] Item 8: re-using the encoder corresponding to the channel information at the initial moment for encoding, where the channel information at the initial moment is the first channel information encoded by the first device.

[0176] Here, reusing the encoder corresponding to the channel information at the initial moment for encoding can also be described as resetting the time-frequency-spatial domain compression window (including the encoder and decoder) or reusing the encoder and decoder corresponding to the initial moment.

[0177] As an implementation manner, the encoder corresponding to the channel information at the initial moment is reused to encode the channel information at the first moment.

[0178] As an implementation manner, the encoder corresponding to the channel information at the initial moment is reused to encode the channel information at moments after the first moment.

[0179] Here, the encoder corresponding to the channel information at the initial moment is reused for encoding, so that the channel information encoding process proceeds normally.

[0180] It should be noted that the intermediate state information in the embodiment of the present application includes or indicates information on the time domain correlation of the channel. Optionally, the information on the time domain correlation of the channel includes or implies the time domain correlation characteristics of the channel, and the time domain correlation characteristics can effectively help the encoder or decoder to encode or decode the channel information, thereby reducing the overhead of the channel reporting information. Exemplarily, the information on the time domain correlation of the channel can be the time domain correlation or cosine similarity of adjacent moments of the channel, or information processed by an AI unit and implying the time domain correlation characteristics of the channel. Optionally, the information on the time domain correlation of the channel may be a single calculation, or it may be a statistical value over a period of time or multiple calculation values.

[0181] Optionally, when performing at least one of the fourth to eighth items in the above-mentioned first operation, second channel reporting information may also be reported.

[0182] In an embodiment of the present application, when it is determined that a problem event occurs in the time-frequency-spatial compression process of the channel information at the first moment, the first device performs a first operation; the first operation includes at least one of the following: sending a first indication message, the first indication message is used to indicate that the channel reporting information adopts a compression method other than the time-frequency-spatial compression method; sending a second indication message for indicating relevant information of the problem event; using the intermediate state information corresponding to the channel information at the second moment to encode the channel information at the third moment, the second moment is before the first moment, and the third moment is after the first moment; not using the intermediate state information corresponding to the channel information at the first moment to encode the channel information at the third moment; clearing the intermediate state information corresponding to the channel information at at least one moment; re-using the encoder corresponding to the channel information at the initial moment for encoding. That is, the above scheme defines the corresponding processing behavior when a problem event occurs in the time-frequency-spatial compression process of the channel information, so as to ensure that the time-frequency-spatial compression of the channel information can be carried out stably in a complex and changeable wireless channel environment, thereby effectively ensuring the performance of the time-frequency-spatial compression.

[0183] Optionally, the method of the embodiment of the present application further includes:

[0184] Determining that a problem event occurs in the compression process of the channel information at the first moment, upon detecting a first problem event in the time-frequency-spatial domain compression process of the channel information at the first moment, receiving third indication information sent by the second device, or not receiving a target timestamp sent by the second device, where the target timestamp is used to indicate that a decoder of the second device is operating normally, or is used to indicate a time when channel reporting information is received, or is used to indicate a decoding time of the decoder;

[0185] Among them, the third indication information is used to indicate that a problem event occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, or to instruct the first device to reuse the encoder corresponding to the channel information at the initial moment for encoding, or to indicate the timestamp corresponding to the problem event.

[0186] Optionally, if no problem occurs in the time-frequency-spatial domain compression process of the channel information, the second device will feedback the target timestamp to the first device. Based on the target timestamp, the first device can obtain the normal operation time of the decoder of the second device or the reception time of the channel reporting information or the decoding time of the decoder.

[0187] In an embodiment of the present application, the first device can determine whether a problem event occurs in the compression process of the channel information at the first moment by detecting the first problem event by itself, or it can determine whether a problem event occurs in the compression process of the channel information at the first moment based on the indication of the second device.

[0188] Optionally, the first problem event includes at least one of the following:

[0189] Problem events corresponding to channel information; that is, problem events corresponding to encoder input information, such as lack of input information or signal problems of input information;

[0190] The problem event corresponding to the encoding process of the channel information, that is, the problem event corresponding to the reasoning process of the channel information;

[0191] The problem event corresponding to the statistical information of the channel information may be statistical information within a preset time period. The preset time period may be set as needed and is not specifically limited in this application.

[0192] Optionally, the problem event corresponding to the channel information includes at least one of the following:

[0193] Channel information is not detected on at least part of the channel information resources; for example, channel information is not detected at all on the channel information resources, or channel information is not detected on part of the channel information resources;

[0194] The signal quality of the channel information detected on at least part of the channel information resources does not meet the preset requirement; illustratively, the signal quality not meeting the preset requirement includes the signal quality being lower than a preset threshold value, for example, the channel information can be detected on the channel information resources, but the signal quality of the detected channel information is lower than the preset threshold;

[0195] The time domain correlation between the channel information at the first moment and the channel information at at least one second moment is less than or equal to a first preset threshold.

[0196] Optionally, the problem event corresponding to the encoding process of the channel information includes at least one of the following:

[0197] The encoding time of the channel information is greater than or equal to a first preset duration; optionally, the encoding duration can also be understood as the duration for the encoder to infer the channel reporting information based on the input channel information.

[0198] The information value of the channel reporting information corresponding to the channel information is an abnormal value, or the format of the channel reporting information corresponding to the channel information does not meet the first preset format requirement. For example, the first preset format requirement is an integer, and the number of channel reporting information is a decimal. In this case, it can be determined that the number of channel reporting information corresponding to the channel information does not meet the first preset format requirement. For example, the first preset format requires K1 bits, and the number of bits of the channel reporting information is K2, where K1 and K2 are positive integers, and K2 is different from K1. For example, the first preset format requirement is between K3 and K4 bits, and the number of bits of the channel reporting information is K5, where K3, K4 and K5 are positive integers, and K4 is greater than K3, K5 is greater than K4, or K5 is less than K3.

[0199] Optionally, the problem event corresponding to the statistical information of the channel information includes at least one of the following:

[0200] The characteristic statistical value of the channel information is outside a first preset range. Exemplarily, the first preset range may be a first characteristic statistical value range corresponding to normal operation of the encoder. The characteristic statistical value may be a variance, mean, probability density distribution, cumulative probability distribution, etc.

[0201] The characteristic statistical value of the channel reporting information corresponding to the channel information is outside a second preset range. The second preset range may be a second characteristic statistical value range corresponding to normal operation of the encoder. The characteristic statistical value may be a variance, mean, probability density distribution, cumulative probability distribution, etc.

[0202] As an implementation manner, the characteristic statistical value includes a characteristic statistical value of a time domain correlation of the channel information.

[0203] Based on whether the characteristic statistical value of the time domain correlation is within the second preset range, it is possible to more accurately determine that a problem event occurs in the time-frequency-space domain compression process of the channel information.

[0204] Optionally, the method of the embodiment of the present application further includes:

[0205] Send target channel reporting information and a timestamp corresponding to the target channel reporting information, where the target channel reporting information is channel reporting information corresponding to the target channel information, and the target channel information is channel information in which no problem event occurs during the compression process.

[0206] If no problem occurs during the time-frequency-spatial domain compression process of the target channel information, the target channel reporting information and the timestamp corresponding to the target channel reporting information are sent. If a problem occurs during the time-frequency-spatial domain compression process of the target channel information, the timestamp corresponding to the target channel information is not reported. Here, by reporting the timestamp corresponding to the target channel information, the second device can obtain the normal operation of the encoder, the reporting time of the target channel information, or the encoding time of the encoder.

[0207] In an embodiment of the present application, corresponding processing behaviors are defined when problem events occur and when problem events occur in the time-frequency-spatial domain compression process of channel information, so as to ensure that the time-frequency-spatial domain compression of channel information can be carried out stably in a complex and changeable wireless channel environment, thereby effectively ensuring the performance of time-frequency-spatial domain compression.

[0208] As shown in FIG6 , the embodiment of the present application further provides a method for processing channel information, including:

[0209] Step 601: When it is determined that a problem event occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, the second device performs a second operation;

[0210] The second device includes a network side device or a terminal. Exemplarily, when the above-mentioned first device is a terminal, the second device is a network side device; when the above-mentioned first device is a network side device, the second device is a terminal.

[0211] Optionally, the first moment mentioned above may include any moment.

[0212] Optionally, the first device comprises at least one decoder.

[0213] Optionally, at least one decoder in the second device corresponds to at least one AI model, for example, one decoder corresponds to one AI model, or multiple decoders correspond to one AI model. The decoder performs compression processing based on the corresponding AI model.

[0214] Optionally, the above-mentioned channel information includes channel information of CSI. Of course, the channel information may also include channel information of positioning information, etc., which is not specifically limited in the embodiments of the present application.

[0215] The above-mentioned time-frequency and spatial domain compression process refers to a compression process using a time-frequency and spatial domain compression method. In this time-frequency and spatial domain compression method, the channel information of the target time moments other than the initial time moment is combined with the intermediate state information output by the encoder corresponding to the previous time moment of the target time moment to encode the channel information of the target time moment. Optionally, the encoder at the initial time moment has no previous intermediate state information to use; or, the encoder at the initial time moment uses channel time domain related information obtained by other means as intermediate state information, such as obtaining channel time domain related information through channel statistical information and inputting it into the encoder at the initial time moment. Specifically, the first encoder that encodes the channel information at the initial time moment outputs the intermediate state information to the second encoder, and the second encoder uses the intermediate state information to encode the channel information of the first target time moment. Optionally, the second encoder also outputs the intermediate state information to a third encoder, and the third encoder is used to encode the channel information of the second target time moment based on the intermediate state information. The first target time moment is located after the initial time moment, and the second target time moment is located after the first target time moment.

[0216] The second operation includes at least one of the following:

[0217] Item 1: Send a third indication message, wherein the third indication message is used to indicate that a problem event occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, or to instruct the first device to reuse the encoder corresponding to the channel information at the initial moment for encoding, or to indicate the timestamp corresponding to the problem event.

[0218] By sending the third indication information, the first device can determine that a problem occurs in the time-frequency-spatial domain compression process of the channel information at the first moment.

[0219] The second item: the target timestamp is not sent, and the target timestamp is used to indicate that the decoder of the second device is working normally, or to indicate the reception time of the channel reporting information, or to indicate the decoding time of the decoder.

[0220] By not sending the target timestamp, the first device can determine that a problem occurs in the time-frequency-space domain compression process of the channel information at the first moment.

[0221] Item 3: Using the intermediate state information corresponding to the channel reporting information at the second moment to decode the channel reporting information at the third moment, wherein the second moment is a moment before the first moment, and the third moment is a moment after the first moment.

[0222] Since there is no problem in the time-frequency-spatial domain compression process of the channel information at the second moment, the intermediate state information corresponding to the channel reporting information at the second moment can still be used to decode the channel reporting information at the third moment, that is, the time-frequency-spatial domain coding method is still used to decode the channel reporting information at the third moment.

[0223] Item 4: Do not use the intermediate state information corresponding to the channel reporting information at the first moment to decode the channel reporting information at the third moment, where the third moment is a moment after the first moment.

[0224] Since a problem occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, there may be a problem with the intermediate state information corresponding to the channel reporting information at the first moment. Here, the intermediate state information corresponding to the channel reporting information at the first moment is not used to decode the channel reporting information at subsequent moments, which is beneficial to improving the compression performance of the channel information at subsequent moments.

[0225] Item 5: Clear the intermediate state information corresponding to the channel reporting information at at least one moment.

[0226] Optionally, clearing the intermediate state information corresponding to the channel reporting information at at least one moment includes clearing the intermediate state information corresponding to the channel reporting information at the first moment.

[0227] Here, since a problem occurs in the time-frequency-spatial domain compression process of the channel information at the first moment, there may be a problem with the intermediate state information corresponding to the channel reporting information at the first moment. The intermediate state information corresponding to the channel reporting information at the first moment is cleared to avoid using the intermediate state information corresponding to the channel reporting information at the first moment for decoding at subsequent moments.

[0228] Optionally, in one embodiment, clearing the intermediate state information corresponding to the channel reporting information at at least one moment includes clearing all the intermediate state information of the decoder.

[0229] Item 6: reusing the decoder corresponding to the channel reporting information at the initial moment for decoding, where the channel reporting information at the initial moment is the first channel reporting information decoded by the second device;

[0230] Here, reusing the encoder corresponding to the channel information at the initial moment for encoding can also be described as resetting the time-frequency-spatial domain compression window (including the encoder and decoder) or reusing the encoder and decoder corresponding to the initial moment.

[0231] As an implementation manner, the decoder corresponding to the channel reporting information at the initial moment is reused to decode the channel reporting information at the first moment.

[0232] As an implementation manner, the decoder corresponding to the channel reporting information at the initial moment is reused to decode the channel reporting information at moments after the first moment.

[0233] It should be noted that the intermediate state information in the embodiment of the present application includes or indicates information on the time domain correlation of the channel. Optionally, the information on the time domain correlation of the channel includes or implies the time domain correlation characteristics of the channel. The time domain correlation characteristics can effectively help the encoder or decoder to encode or decode the channel information, thereby reducing the overhead of the channel reporting information. Exemplarily, the information on the time domain correlation of the channel can be the time domain correlation or cosine similarity of adjacent moments of the channel, or information processed by an AI unit and implicitly including the time domain correlation characteristics of the channel.

[0234] In an embodiment of the present application, when it is determined that a problem event occurs in the time-frequency and spatial domain compression process of the channel information at the first moment, the second device performs a second operation; the second operation includes at least one of the following: sending a third indication information, the third indication information is used to indicate that a problem event occurs in the time-frequency and spatial domain compression process of the channel information at the first moment or instruct the first device to reuse the encoder corresponding to the channel information at the initial moment for encoding or indicate the timestamp corresponding to the problem event; not sending a target timestamp, the target timestamp is used to indicate that the decoder of the second device is working normally or to indicate the receiving time of the channel reporting information or to indicate the decoding time of the decoder; using the intermediate state information corresponding to the channel reporting information at the second moment to decode the channel reporting information at the third moment; not using the intermediate state information corresponding to the channel reporting information at the first moment to decode the channel reporting information at the third moment; clearing the intermediate state information corresponding to the channel reporting information at at least one moment; reusing the decoder corresponding to the channel reporting information at the initial moment for decoding, and the channel reporting information at the initial moment is the first channel reporting information decoded by the second device. That is, the above scheme defines the corresponding processing behavior when a problem event occurs in the time-frequency-spatial domain compression process of the channel information, so as to ensure that the time-frequency-spatial domain compression of the channel information can be carried out stably in a complex and changeable wireless channel environment.

[0237] The first indication information is used to indicate a first compression mode corresponding to the channel reporting information, where the first compression mode is a compression mode other than the time-frequency-spatial domain compression mode, and the channel reporting information is obtained by encoding the channel information at the first moment using the first compression mode;

[0238] The second indication information is used to indicate relevant information of the problem event;
