[0165] In some embodiments, the first measurement result is used to determine the second information. In the disclosed embodiments, after obtaining the first measurement result, the terminal also needs to compress the first measurement result to enable transmission of the first measurement result. The first decoding model is located in the terminal. Optionally, the first decoding model and the second decoding model have the same function, and the second decoding model is located in the network device. Optionally, the terminal monitors the decoding process of the second decoding model by detecting the decoding process of the first decoding model.

[0166] Step S2103: The terminal encodes the first measurement result using a first coding model to obtain first data.

[0167] In some embodiments, the first decoding model is used to decode first data of the terminal. In some embodiments, the first data is obtained based on encoding the first measurement result.

[0168] In some embodiments, a first coding model is provided in the terminal. After obtaining a first measurement result through measurement, the first measurement result is input into the first coding model, and the first coding model encodes the first measurement result to obtain first data.

[0169] Optionally, the first data refers to a measurement result obtained by reducing the data volume of the first measurement result.

[0170] Optionally, the first data refers to a measurement result obtained by compressing and quantizing the first measurement result.

[0171] In some embodiments, the first measurement result may also be understood as ground-truth CSI.

[0172] Step S2104: The terminal decodes the first data using the first decoding model to obtain second data.

[0173] In some embodiments, a first decoding model is provided in the terminal. After the first encoding model outputs the first data, the first data can be input into the first decoding model, and the first decoding model decodes the first data to obtain the second data.

[0174] In some embodiments, the first encoding model in the terminal is connected to the first decoding model, and the output of the first encoding model is the input of the first decoding model.

[0175] Step S2105: The terminal determines first information of the first decoding model based on the second data and the first measurement result.

[0176] In the embodiment of the present disclosure, since the measurement result obtained after encoding and decoding the first measurement result is different from the first measurement result, after decoding to obtain the second data, it is necessary to obtain the similarity value between the second data and the first measurement result, and then determine the first information of the first decoding model.

[0177] In some embodiments, the above steps S2103 to S2105 may be performed multiple times to obtain multiple similarity values, which is not limited in the embodiments of the present disclosure.

[0178] Step S2106: The terminal sends first information of the first decoding model to the network device.

[0179] In some embodiments, the first information is used to characterize the similarity between the first decoding model set at the terminal and the second decoding model set at the network device. Alternatively, the first information can also be understood as the first information being used to characterize the difference between the first decoding model set at the terminal and the second decoding model set at the network device. Alternatively, the first information can also be understood as the first information being used to characterize the difference in operating performance between the first decoding model set at the terminal and the second decoding model set at the network device.

[0180] That is, the difference between the first decoding model at the terminal and the second decoding model set at the network device can be determined through the first information.

[0181] In some embodiments, the first decoding model is used by the terminal to decode the first data, and the second decoding model is used by the network device to decode the received first data; the first data is obtained by the terminal encoding the first measurement result.

[0182] In some embodiments, the first information includes at least one of the following:

[0183] (1) Second information and third information.

[0184] In some embodiments, the second information is used to represent the difference between the second data obtained by decoding the first data by the first decoding model and the first measurement result. The third information is used to represent the difference between the decoding performance of the second decoding model and the decoding performance of the first decoding model. Optionally, the third information is the difference between the historical similarity of the second decoding model and the historical similarity of the first decoding model. Alternatively, it can be understood that the third information refers to the difference between the first decoding model and the second decoding model.

[0185] In some embodiments, the decoding performance of the first decoding model includes the difference between the second data obtained by the first decoding model decoding the first data and the first measurement result, and the decoding performance of the second decoding model includes the difference between the third data obtained by the second decoding model decoding the first data and the first measurement result.

[0186] Optionally, the decoding performance of the first decoding model includes expressing a cosine similarity between a difference between second data obtained by decoding the first data by the first decoding model and the first measurement result. Optionally, the decoding performance of the second decoding model includes expressing a cosine similarity between a difference between third data obtained by decoding the first data by the second decoding model and the first measurement result.

[0187] In some embodiments, the differences in the embodiments of the present disclosure are represented by similarities such as cosine similarity, Mahalanobis distance, and Pearson similarity, which are not limited in the embodiments of the present disclosure.

[0188] In some embodiments, the third information is agreed upon by a communication protocol, or is determined by a difference between a first similarity of the first decoding model and a second similarity of the second decoding model.

[0189] Optionally, a difference between a first similarity of the first decoding model and a second similarity of the second decoding model is determined as the third information.

[0190] Optionally, the first decoding model may obtain multiple first similarities and second similarities corresponding to the first similarities, then obtain an average of the multiple first similarities and an average of the multiple second similarities, and determine the difference between the average of the first similarities and the average of the second similarities as the third information.

[0191] Optionally, the first similarity can be obtained by using the above steps S2103-S2105. The second similarity is similar to the first similarity, and the execution process only requires replacing the first decoding model with the second decoding model.

[0192] Specifically, the terminal sends the first data to the network device, and the network device decodes the first data using the second decoding model to obtain second data, and then determines the second similarity based on the second data and the first measurement result.

[0193] In some embodiments, after obtaining the similarity value through the above steps S2103 - S2105 , the terminal may simply carry the sum of the similarity value and the third information in the first information.

[0194] It should be noted that the second decoding model is set in the network device, and the first decoding model and the second decoding model have the same function.

[0195] (2) The sum of the second information and the third information.

[0196] (3) The magnitude relationship between the sum of the second information and the third information and the first similarity threshold.

[0197] In some embodiments, the first similarity threshold is agreed upon by a communication protocol, or configured by a network device, or set by the terminal itself, which is not limited in the embodiments of the present disclosure.

[0198] In some embodiments, a preset bit value is used to indicate the size relationship. Optionally, if the sum of the second information and the third information is greater than a first similarity threshold, a preset bit value of 1 is used for indication. If the sum of the second information and the third information is not greater than the first similarity threshold, a preset bit value of 0 is used for indication. If the sum of the second information and the third information is greater than the first similarity threshold, a preset bit value of 0 is used for indication. If the sum of the second information and the third information is not greater than the first similarity threshold, a preset bit value of 1 is used for indication.

[0199] (4) Second information.

[0200] In the embodiment of the present disclosure, the first information only needs to carry the second information itself.

[0201] (5) The magnitude relationship between the second information and the second similarity threshold.

[0202] In some embodiments, the second similarity threshold is agreed upon by a communication protocol, or configured by a network device, or set by the terminal itself, which is not limited in the embodiments of the present disclosure.

[0203] In some embodiments, a preset bit value is used to indicate the size relationship. Optionally, if the second information is greater than a second similarity threshold, a preset bit value of 1 is used for indication. If the second information is not greater than the second similarity threshold, a preset bit value of 0 is used for indication. If the second information is greater than the second similarity threshold, a preset bit value of 0 is used for indication. If the second information is not greater than the second similarity threshold, a preset bit value of 1 is used for indication.

[0204] (6) Similarity calculated based on a specific codebook type.

[0205] In some embodiments, the terminal may select a corresponding codeword based on the original CSI measurement result and the codebook based on the codebook type configured by the base station, such as the enhanced Type II codebook, calculate feature vector information based on the original CSI measurement result, and calculate similarity based on the codeword and feature vector information.

[0206] (7) The magnitude relationship between the sum of the second information and the third information and the similarity calculated based on the specific codebook type.

[0207] In some embodiments, a preset bit value is used to indicate the size relationship.

If the sum of the second information and the third information is not greater than the similarity calculated based on the specific codebook type, a preset bit value of 1 is used for indication.

[0208] Step S2107: The network device receives the first information of the first decoding model sent by the terminal.

[0209] It should be noted that the network device will also send configuration information to the terminal. The terminal receives the configuration information and then sends the first information to the network device based on the configuration information.

[0210] In some embodiments, the configuration information is used to indicate the configuration of the terminal when sending the first information.

[0211] In some embodiments, the configuration information includes at least one of the following:

[0212] (1) Report configuration identification.

[0213] In some embodiments, the report configuration identifier is used to indicate the configuration of the first information sent by the terminal. In some embodiments, the report configuration identifier refers to a Monitor report configuration / setting ID (Monitor report configuration ID).

[0214] (2) Type of the first information.

[0215] In some embodiments, the type of the first information is used to indicate the type of the first information reported. In some embodiments, the type of the first information is at least one of the first information in the example of step S2106 above. In some embodiments, the type of the first information is Report quantity.

[0216] (3) Time domain type.

[0217] In some embodiments, the time domain type includes any one of a semi-static type and a non-periodic type. In some embodiments, the time domain type refers to a time domain feature.

[0218] (4) Frequency domain type.

[0219] The frequency domain type includes any one of a broadband type and a narrowband type. In some embodiments, the frequency domain type refers to a frequency domain feature.

[0224] In some embodiments, the associated downlink reference signal resource includes at least one of the following:

[0225] Reference signal resource identifier;

[0226] Reference signal resource set identifier;

[0227] Reference signal resource configuration identifier;

[0228] DMRS (Demodulation Reference Signal) resources.

[0229] The following describes the information exchanged and transmitted between the terminal and the network device by taking an example.

[0230] For example, the terminal reports the third information or the identifier of the second decoding model to the base station, and the identifier of the second decoding model has a corresponding relationship with the third information. The base station sends configuration information to the terminal, where the configuration information includes that the reporting amount configuration is the second information and semi-static reporting. The resource for sending the first information is PUCCH (Physical Uplink Control Channel) resource #1. The base station sends the CSI-RS resource associated with the reporting configuration to the terminal. The base station sends MAC CE information activation configuration information to the terminal. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE (media access control Control Element) in slot n. The terminal starts sending the second information on PUCCH resource #1 in slot n+X. The base station sends MAC CE information deactivation configuration information to the terminal. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE in slot n. The terminal stops sending the second information on PUCCH resource #1 in slot n+Y.

[0231] For example, the base station sends configuration information to the terminal, where the configuration information includes that the reporting amount configuration is the sum of the second information and the third information, semi-static reporting, and the reporting resource is configured as PUCCH resource #1. The base station sends CSI-RS resources associated with the reporting configuration to the terminal, and the base station sends MAC CE information to activate specific configuration information to the terminal. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE in slot n, and the terminal starts sending the sum of the second information and the third information on PUCCH resource #1 in slot n+X. The base station sends MAC CE information to the terminal to deactivate the configuration information. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE in slot n, and the terminal stops sending the sum of the second information and the third information on PUCCH resource #1 in slot n+Y.

[0232] For example, the base station sends configuration information to the terminal, the configuration information including that the reporting amount configuration is the comparison result of the sum of the second information and the third information and the first similarity threshold, semi-static reporting, the reporting resource configuration is PUCCH resource#1, and the adopted codebook type is eTypeII. The base station sends the CSI-RS resources associated with the reporting configuration to the UE, and the base station sends MAC CE information activation configuration information to the terminal. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE in slot n. The UE starts sending the comparison result of the sum of the second information and the third information with the first similarity threshold on PUCCH resource #1 in slot n+X. The sum of the second information and the third information is greater than the first similarity threshold, and feedback 1 is given. The sum of the second information and the third information is less than the first similarity threshold, and feedback 0 is given. The base station sends MAC CE information deactivation configuration information to the terminal. The terminal sends HARQ-ACK (acknowledgement) information for the PDSCH containing the MAC CE in slot n. The UE stops sending the comparison result of the sum of the second information and the third information with the first similarity threshold on PUCCH resource #1 in slot n+Y.
