[0035] The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0036] It is worth noting that the artificial intelligence (AI) unit mentioned later in the embodiments of the present application can also be understood as an AI model, which can also be called an AI module, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI characteristic, a machine learning model, a neural network, a neural network function, a neural network function, a decision tree, a support vector machine, a Bayesian classifier, etc., without specific limitation.

[0037] like Figure 2 FIG. 2 is a flow chart of a signal reporting method 200 provided by an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 may at least include the following steps.

[0038] S210, the terminal sends first information to the network side device.

[0039] The first information is used to characterize the second channel related information, and the second channel related information is obtained by the terminal compressing and mapping the measured first channel related information. For example, the terminal can obtain the first channel related information by receiving a measurement reference signal (Channel state information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), etc.) sent by a network side device and measuring it, and compressing and mapping the first channel related information using a compression mapping method to obtain the second channel related information. The compression mapping method can be implemented by protocol agreement, network side configuration, terminal determination, etc., and is not limited here.

[0040] That is, in this embodiment, the terminal can remove redundant information in the measured first channel-related information through compression mapping, extract more refined channel-related information, and then report the extracted information (such as second channel-related information) to the network side device. It can use a smaller number of data transmission bits to transmit more comprehensive channel-related information to meet the accuracy requirements of the network side device when performing processes such as precoding matrix determination and AI unit training or monitoring of beam prediction use cases based on the received channel-related information.

[0041] In this embodiment, "the first information is used to characterize the second channel related information" can be understood as: the first information directly includes the second channel related information to be transmitted, and may also include a variable of the second channel related information to be transmitted relative to the second channel related information transmitted last time, etc., and its implementation method is not limited here.

[0042] The first channel-related information (also referred to as original channel-related information) may include but is not limited to channel quality information (such as layer 1 reference signal received power (layer 1 reference signal received power, L1-RSRP), L1-reference signal received quality (reference signal received quality, RSRQ), L1-signal-to-noise and interference ratio (signal-to-noise and interference ratio, SINR), L3-RSRP, L3-RSRQ, L3-SINR, etc.), channel state information (bare channel characterization or eigenvector characterization), beam quality information, etc., without limitation here.

[0043] Correspondingly, when the network side device receives the first information, it can determine the first channel related information based on the first information, such as using a decompression mapping method corresponding to the terminal (corresponding to the compression mapping method used on the terminal side) to achieve the determination and recovery of the first channel related information.

[0044] It is worth noting that the aforementioned "compression mapping" is similar to the compression mapping of RGB images, which can be implemented based on the ViT (Vision Transformer) structure. For example, for a channel-related information, it can be represented as a multidimensional vector, and then the multidimensional vector is divided into multiple information blocks (also called pixel blocks). From the input of the ViT structure, the embedded vector can be regarded as a token, and the positions of the information blocks corresponding to these tokens are sorted from the upper left to the lower right to obtain a token sequence, and then after a fully connected (FC) layer linear transformation, each information block token becomes an embedded vector of a channel, and then the compression mapping is completed based on the embedded vector.

[0045] Based on this, in this embodiment, when the terminal compresses and maps the first channel-related information into the second channel-related information, it can regard the first channel-related information as an image, which may include three dimensions of length, width, and channel, and then perform subsequent compression mapping based on the first channel-related information represented by these three dimensions.

[0046] For example, if the first channel-related information includes beam quality information, which can be understood as an image, then the representation of the beam quality information may include at least one of the following (11)-(12).

[0047] (11){transmitting beam horizontal direction, transmitting beam vertical direction, receiving beam information}.

[0048] (12) {transmitting beam direction, receiving beam direction, channel-related information acquisition time}.

[0049] The beam quality information (such as L1-RSRP) can be understood as the pixel value of the image.

[0050] For another example, if the first channel-related information includes channel information, which can be understood as an image, then the channel information is represented by [first dimension information, second dimension information, third dimension information]; wherein the first dimension information, the second dimension information, and the third dimension information are different (i.e., each representation does not include repeated or identical elements). In this embodiment, the first dimension information, the second dimension information, or the third dimension information includes any one of the following (21)-(29).

[0051] (20) Transceiver antenna, including a transmitting antenna and a receiving antenna.

[0052] (21) Transmitting antenna.

[0053] (22) Receiving antenna.

[0054] (23) Frequency resources.

[0055] (24) Channel information acquisition time.

[0056] (25) The complex real or imaginary part of the channel matrix.

[0057] (26) Doppler domain related information, such as Doppler frequency, etc.

[0058] (27)Multipath.

[0059] (28) Delay expansion.

[0060] (29)Angle expansion.

[0061] Based on this, the channel information may be represented by, but is not limited to, {transceiver antennas (i.e., receiving antennas and transmitting antennas), frequency resources, complex real or imaginary parts in the channel matrix}, {transceiver antennas, delay spread, multipath}, etc.

[0062] Among them, when the channel information is represented by {transceiver antennas (i.e., receiving antennas and transmitting antennas), frequency resources, complex real part or imaginary part in the channel matrix}, the amplitude value of the real part or imaginary part in the channel matrix can be understood as the pixel value of the image.

[0063] When the channel information is represented by {transmitting and receiving antennas, delay spread, multipath}, the power on each path is understood as the pixel value of the image.

[0064] In one implementation, the representation of the aforementioned first channel related information may be determined by a network side device, a terminal, a protocol, or the like.

[0065] For example, if the representation method of the first channel-related information is determined by the terminal, the terminal may send fourth indication information to the network-side device, wherein the fourth indication information is used to indicate the representation method of the first channel-related information, so that the terminal and the network-side device have a consistent understanding of the representation method of the first channel-related information, thereby restoring the accuracy of the information in the information reporting process. Optionally, depending on different communication requirements, the fourth indication information can be reported to the network-side device alone, or it can be reported together with the aforementioned seventh information, which is not limited here.

[0066] For another example, when the representation method of the first channel related information is determined by the network side device, the network side device may send fifth indication information to the terminal, and correspondingly, the terminal receives the fifth indication information sent by the network side device, and the fifth indication information is used to indicate the representation method of the first channel related information, so that the terminal and the network side device have consistent understanding of the representation method of the first channel related information, thereby restoring the accuracy of the information in the information reporting process.

[0067] In this embodiment, the terminal processes the first channel-related information by means of compression mapping, can remove redundant information in the measured first channel-related information, extract more refined channel-related information, and then report the extracted information (such as second channel-related information) to the network side device. It can use a smaller number of data transmission bits to transmit more comprehensive channel-related information to meet the accuracy requirements of the network side device when performing processes such as precoding matrix determination and AI unit training or monitoring of beam prediction use cases based on the received channel-related information.

[0068] like Figure 3 FIG. 3 is a flow chart of a signal reporting method 300 provided by an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 300 may at least include the following steps.

[0069] S310, the terminal sends first information to the network side device.

[0070] The first information is used to represent the second channel related information, and the second channel related information is obtained by the terminal performing compression mapping on the first channel related information obtained by measurement.

[0071] It can be understood that in addition to referring to the relevant description in the aforementioned method embodiment 200, the implementation process of S310 can, as a possible implementation method, include but is not limited to at least one of the following (31)-(32).

[0072] (31) Information related to the second channel.

[0073] Optionally, the second channel-related information is determined based on third information and fifth information; wherein the fifth information is obtained by processing the first channel-related information in a first compression mapping manner. The first compression mapping manner includes a nonlinear transformation or a linear transformation to remove redundant information in the first channel-related information and extract more refined representation information, that is, the fifth information is a representation of the first channel-related information in a latent space.

[0074] The third information is used to indicate the amount of information (or length) of each block in the fifth information, wherein different blocks may correspond to the same or different amounts of information, thereby improving quantization flexibility and optimizing transmission bits corresponding to different blocks. In this embodiment, the third information includes at least one of the following (a)-(e).

[0075] (a) Quantization interval. Wherein, the quantization interval = ceil((ba) / 2 k ), where b is the upper quantization boundary, a is the lower quantization boundary, ceil means rounding up, and k is the quantization precision.

[0076] (b) Quantification of the number of intervals.

[0077] (c) Quantization accuracy; wherein the quantization accuracy can be represented by the number of quantization bits.

[0078] (d) Quantized upper boundary.

[0079] (e) Quantized lower boundary.

[0080] Based on this, in one implementation, the second channel related information is determined based on the third information and the fifth information, including: dividing the fifth information into multiple blocks; inputting the multiple blocks and the third information into the first AI unit, and inferring the second channel related information. Therefore, on the one hand, by dividing into different blocks for transmission, rate matching (or allocation) can be performed for multiple blocks, so that each block has a different rate according to the entropy size, thereby improving the information transmission efficiency. On the other hand, the quantization accuracy of different blocks is determined by using the probability distribution corresponding to different blocks, and the number of bits required for transmission can be further optimized.

[0081] It is worth noting that the fifth information is obtained by the terminal processing the first channel related information according to the first compression mapping method. For example, the first channel related information can be input into the second AI unit to infer the fifth information; wherein, the second AI unit is implemented based on the first compression mapping method.

[0082] In addition, when the fifth information is divided into blocks, the number of blocks can be determined by the terminal, indicated by the network side, agreed upon by the protocol, etc. Wherein, when the number of blocks can be determined by the terminal, the terminal can also report the number of blocks, such as reporting the number of blocks to the network side device separately, or reporting it together with the seventh information mentioned below, etc., which is not limited here.

[0083] (32) second information, where the second information is used to indicate the amount of information of each block in the second channel-related information (or the length of the second channel-related information). In this embodiment, by reporting the second information, the network side device can recover the first channel-related information in combination with the second information and the second channel-related information, so as to improve the reliability of information recovery.

[0084] Similar to the third information, the second information may also include at least one of the following (a)-(e).

[0085] (a) Quantization interval.

[0086] (b) Quantification of the number of intervals.

[0087] (c) Quantization accuracy.

[0088] (d) Quantized upper boundary.

[0089] (e) Quantized lower boundary.

[0090] In one implementation, the process of determining the second information or the third information may include: the terminal inputs the fourth information into the third AI unit to obtain an inference result (posterior probability distribution characteristics, such as variance or mean, etc.), obtains the sixth information based on the inference result and the fifth information, and the sixth information is used to characterize the posterior probability distribution of the fifth information under the condition of the fourth information, and then determines the second information based on the entropy value represented by the sixth information. Among them, the fourth information is obtained by processing the fifth information according to the second compression mapping method (such as nonlinear transformation method, etc.). In other words, the fourth information is the representation of the sixth information in the latent space.

[0091] Alternatively, the terminal inputs the fifth information into the fourth AI unit to obtain an inference result (prior probability distribution characteristics, such as variance or mean, etc.), and determines the sixth information based on the inference result, and the sixth information is used to characterize the prior probability distribution of the fifth information; and then determines the second information based on the entropy value represented by the sixth information.

[0092] For example, assuming that the second information or the third information is the quantization accuracy, then it can be identified as -logP(y), where y is the fifth information after uniform quantization, P(y) is the prior probability distribution of y or the posterior probability distribution based on the fourth information, and the distribution characteristic is the sixth information.

[0093] It is worth noting that in the process of determining the aforementioned second information or third information, the fifth information can be first processed through a second compression mapping method (such as a nonlinear transformation method) to obtain the fourth information, and then the posterior probability distribution of the fifth information is obtained through the fourth information and the feature posterior model, or the prior probability distribution of the fifth information is directly obtained according to the fifth information and the feature prior model, and then the bandwidth of each block of the fifth information is adaptively adjusted based on the posterior probability distribution or the prior probability distribution, or, thereby, the transmission bits can be greatly saved and the transmission efficiency can be improved.

[0094] Correspondingly, after receiving the first information, such as the second channel-related information and the second information, the network side device can restore the second channel-related information according to the second information to obtain the tenth information (such as performing source channel decoding processing (or first performing noise reduction processing and then performing source channel decoding processing; or first performing noise reduction processing and then performing source decoding processing) according to the second channel-related information and the second information, etc., to obtain the tenth information); restore the tenth information according to the first decompression mapping method (the first decompression mapping method corresponds to the first compression mapping method) to obtain the first channel-related information, thereby realizing the recovery of the first channel-related information.

[0095] It should be noted that the network side device recovers the second channel related information based on the second information, which can be understood as: when the network side device receives the second channel related information and the second information, it can first decode the second information, and then recover the second channel related information based on the successfully decoded second information.

[0096] Of course, if the first information only includes the second channel related information, then the network side device can restore the second channel related information according to the preset second information, and no limitation is made here.

[0097] In one implementation, the terminal may report fourth information while reporting the second channel-related information and the second information. That is, the first information may also include the fourth information. Thus, the posterior probability distribution characteristics of the fifth information may be determined through the fourth information, thereby further improving the accuracy of information recovery of the network side device when performing information recovery based on the second channel-related information.

[0098] For example, when the network side device receives the second channel related information, the second information, and the fourth information, it can Figure 4aAs shown, the posterior probability distribution characteristics of the fifth information under the condition of the fourth information are determined according to the fourth information, and then the tenth information is determined according to the second channel related information, the second information and the posterior probability distribution (such as performing source channel decoding processing, noise reduction processing, etc. according to the second channel related information, the second information and the posterior probability distribution to obtain the tenth information), and finally, the tenth information is restored according to the first decompression mapping method (the first decompression mapping method corresponds to the first compression mapping method) to obtain the first channel related information, thereby achieving accuracy and reliability in the recovery of the first channel related information.

[0099] Of course, the aforementioned process of the network side device determining the posterior probability distribution characteristics of the fifth information under the condition of the fourth information may include: inputting the fourth information into the fifth AI unit to obtain an inference result; and determining the posterior probability distribution characteristics of the fifth information under the fourth information based on the inference result.

[0100] It is worth noting that the fifth AI unit used by the network side device when recovering the first channel-related information shares the network structure and parameters with the third AI unit used by the terminal. That is to say, the network side device uses a shared knowledge base (modeling of the posterior probability distribution of the fifth information under the fourth information) to recover information. In this way, on the one hand, the compression amount can be reduced, and on the other hand, the accuracy of information recovery can be ensured when the network side device recovers channel-related information.

[0101] Optionally, the AI ​​unit may be pre-configured in the network side device, and its implementation may be achieved by the network side device or the terminal, or may be obtained by joint training of the terminal and the network side device, which is not limited here.

[0102] In one implementation, before sending the first information to the network side device, the terminal may also send seventh information to the network side device to ensure the accuracy and reliability of information reporting. For example, in this embodiment, the seventh information may include but is not limited to at least one of the following (41)-(44).

[0103] (41) The first indication information is used to align the AI ​​units used by the terminal and the network side device in the information reporting process, so that the terminal and the network side device can match the AI ​​units used in the information reporting process, and then the network side device can use the adapted AI unit to perform information recovery, etc., to ensure the validity of the AI ​​unit reasoning.

[0104] Optionally, the first indication information is used to indicate at least one of the following (411)-(413).

[0105] (411) The AI ​​unit used by the terminal during information reporting enables the network side device to know the AI ​​unit used by the terminal during information reporting, so as to activate the AI ​​unit corresponding to the network side device for subsequent information recovery.

[0106] (412) The AI ​​unit used by the network side device during the information reporting process, to instruct the network side device to use the indicated AI unit for subsequent information recovery.

[0107] (413) The terminal and the network side device share an AI unit during the information reporting process, thereby enabling the network side device to restore the received channel-related information based on the shared AI unit, thereby reducing the compression amount on the one hand and improving the accuracy of information recovery on the other hand.

[0108] (42) second indication information, used to indicate a processing object corresponding to the second channel related information.

[0109] For example, the second indication information may indicate that the second channel-related information is obtained by the terminal processing measured channel information or channel quality information or beam quality information, etc.

[0110] (43) third indication information, used to indicate a processing purpose or use corresponding to the second channel related information.

[0111] For example, the third indication information can be used to indicate that the second channel-related information is used for high-fidelity reporting (such as bare information reporting), for model training or model monitoring, for user precoding determination, beam selection, channel estimation, etc., thereby ensuring the accuracy of the subsequent use of the second channel-related information.

[0112] (44) Terminal capability information, used to indicate that the channel-related information reported by the terminal includes the second information and the second channel-related information, so that the network-side device enables the terminal to use the information reporting method provided in the present application for reporting; otherwise, if the terminal capability information is not reported, it can be considered that the terminal uses a codebook or conventional (legacy) method for information reporting.

[0113] In one implementation, there may be multiple training methods for the AI ​​unit involved in the information reporting process. For example, the network side device may fix the AI ​​unit parameters after training, and the terminal may continue to train the AI ​​unit on its side. Or, the terminal may fix the AI ​​unit parameters after training, and the network side device may continue to train the AI ​​unit on its side. Or, the network side device and the terminal may jointly train, and there is no limitation here.

[0114] In this case, several different situations in Mode 1 to Mode 4 are described below.

[0115] Mode 1: The terminal receives the eighth information sent by the network side device, wherein the eighth information is used to indicate to the terminal the model structure of the AI ​​unit involved in information reporting, and to determine the model according to the eighth information. That is, the AI ​​unit involved in the information reporting by the terminal is determined by the network side device and indicated to the terminal.

[0116] Among them, for mode 1, in order to ensure that the eighth information indicated by the network side device to the terminal matches the needs of the terminal, as an implementation method, the terminal may send ninth information to the network side device, and the ninth information is used to indicate the model structure or model size supported by the terminal. Correspondingly, the network side device may determine the eighth information according to the ninth information.

[0117] Mode 2: The terminal receives the eighth information sent by the network side device, wherein the eighth information is used to indicate to the terminal the model parameter update information of the AI ​​unit involved in the information reporting, and to update the model parameters according to the eighth information. In the case where the AI ​​unit is jointly trained by the terminal and the network side device, the model parameter update information may include the gradient of the AI ​​unit segmentation layer, the parameter gradient of the AI ​​unit shared by the network side device, etc. Among them, the model parameter update information may be but is not limited to being determined by the network side device based on the original beam quality reported by the terminal and the output result of the relevant AI unit. It can be understood that for the case of joint training of the terminal and the network side device, the segmentation layer is the segmentation point between the terminal side neural network model and the network side network model. The parameter gradient of the AI ​​unit shared by the network side device is included only when the network side device and the terminal have a shared AI unit, otherwise this item is not included.

[0118] Mode 3: The terminal receives the eighth information sent by the network side device, wherein the eighth information is used to indicate to the terminal the model parameter update information of the AI ​​unit involved in the information reporting, and to update the model parameters according to the eighth information. For example, when the AI ​​unit is first trained by the network side device and the terminal then trains the AI ​​unit on this side, the eighth information includes the model parameters of the network side AI unit, or the network structure and model parameters.

[0119] Method 4: The terminal sends the model parameters of the AI ​​unit on the terminal side, or the network structure and model parameters to the network side device, and then the network side device performs model training and parameter updates on the AI ​​unit on this side based on this.

[0120] Based on the description of the aforementioned method embodiments 200-300, the information reporting process provided by the embodiments of the present application is further exemplified in combination with Example 1 and Example 2, as follows: For ease of description, it may be assumed in the following examples that the first channel related information is beam quality information.

[0121] Example 1

[0122] (1) Please refer to Figure 4a When information reporting is required, the terminal compresses and maps the first beam quality information into fifth information through a first compression mapping method, and compresses and maps the fifth information into fourth information through a second compression mapping method.

[0123] (2) Dividing the fifth information into a plurality of blocks, and inputting the plurality of blocks and the third information into the first AI unit to obtain the second beam quality information.

[0124] And input the fourth information into the third AI unit to obtain an inference result, obtain sixth information according to the inference result and the fifth information, and the sixth information is used to characterize the posterior probability distribution of the fifth information under the condition of the fourth information; based on the entropy value represented by the sixth information, determine the second information.

[0125] (3) Sending the second beam quality information and the second information to the network side device through a communication channel. Figure 4a As shown, when the second beam quality information and the second information are sent, the second information and different blocks in the second beam quality information are adaptively rate matched and encoded (such as source channel coding or source coding, etc.) before being sent. The adaptive rate matching and encoding involved are not described in detail here.

[0126] (4) After receiving the second beam quality information and the second information, the network side device may perform information recovery according to the second beam quality information and the second information to obtain tenth information.

[0127] (5) Processing the tenth information in a first decompression and mapping manner to obtain the first beam quality information.

[0128] It is worth noting that in one implementation, if the terminal also reports the fourth information when reporting the information, then please refer to Figure 4a , the network side device can determine the posterior probability distribution characteristics of the fifth information under the condition of the fourth information based on the fourth information, and then determine the tenth information based on the second beam quality information, the second information and the posterior probability distribution.

[0129] Example 2

[0130] (1) Please refer to Figure 4b When information reporting is required, the terminal compresses and maps the first beam quality information into fifth information through a first compression mapping method.

[0131] (2) Dividing the fifth information into a plurality of blocks, and inputting the plurality of blocks and the third information into the first AI unit to obtain the second beam quality information.

[0132] And input the fifth information into the fourth AI unit to obtain an inference result, determine the sixth information according to the inference result, and the sixth information is used to characterize the prior probability distribution of the fifth information; based on the entropy value represented by the sixth information, determine the second information.

[0133] (3) Sending the second beam quality information and the second information to a network side device through a communication channel.

[0134] (4) After receiving the second beam quality information and the second information, the network side device may perform information recovery according to the second beam quality information and the second information to obtain tenth information.

[0135] (5) Processing the tenth information in a first decompression and mapping manner to obtain the first beam quality information.

[0136] It should be noted that, compared with Example 1, in Example 2, considering that the probability distribution model is a priori probability distribution model, it is not necessary to perform a second compression mapping on the fifth information to obtain the fourth information.

[0137] In addition, the aforementioned Example 1 and Example 2 are merely exemplary descriptions, and their implementation process may include but is not limited to the aforementioned content.
