Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, terminal and network equipment for reporting channel state information. Background Technology

[0002] In User Equipment (UE) side (also known as terminal) Artificial Intelligence (AI) / Machine Learning (ML) model prediction, the terminal requires network-configured reference signals for UE-side model performance monitoring. However, if the complete set of resources that the model needs to predict is used as the measurement resource for performance monitoring, the network requires too many reference signals for model monitoring; if a non-complete set of resources that the model needs to predict is used as the measurement resource for performance monitoring, the terminal needs to determine the effective monitoring time, and the number of effective monitoring times is uncertain, and it faces the problem of inaccurate monitoring parameters obtained from performance monitoring.

[0003] Therefore, it is necessary to improve the method of performance monitoring on the UE side so that when the terminal performs performance monitoring based on the obtained monitoring configuration resources, it can ensure the accuracy and reliability of the measurement resources for performance monitoring.

[0132] The following section will first introduce the content related to the solutions provided in the embodiments of this application.

[0133] Beam management includes two use cases: spatial prediction (BM-Case 1) and temporal prediction (BM-Case 2). Spatial prediction (BM-Case 1) refers to predicting the Top-K (K≥1) beams in Set A at the same time based on Set B measured at a certain time. Temporal prediction (BM-Case 2) refers to predicting the Top-K beams of Set A at the next N times based on Set B measured at M historical times.

[0134] AI / ML models in beam management use cases can be deployed on the network side or the UE side. As data-driven algorithms, AI / ML models suffer from generalization problems. When the channel environment or conditions of the actual system are inconsistent with those during the model training phase, the performance of the AI / ML model may degrade. To ensure the performance of AI / ML models applied to communication systems, a performance monitoring process can be used to monitor whether the performance of the AI ​​model or AI function degrades.

[0135] In AI / ML model prediction, the terminal requires network configuration reference signals for performance monitoring of the model on the UE side. However, if the complete SetA beam that the model needs to predict is used as the measurement resource for performance monitoring, too many reference signals are required for model monitoring; if an incomplete SetA beam that the model needs to predict is used as the measurement resource for performance monitoring, the terminal needs to determine the effective monitoring time, and the number of effective monitoring times is uncertain, and the monitoring parameters obtained from performance monitoring are inaccurate.

[0136] Specifically, such as Figure 1As shown, a dedicated resource set for performance monitoring can be either a complete Set A or a partial Set A. If a complete Set A is used, the base station needs to send all reference signals in Set A, and the UE obtains the actual optimal beam after measurement. However, this comes at the cost of a large number of reference signals (RS) required for performance monitoring, failing to achieve the goal of saving reference signals needed for beam scanning. If a partial Set A is used, the base station only needs to send a small number of reference signals for performance monitoring. However, if the reference signal resources in the partial Set A are not configured reasonably, the actual optimal beam may not be obtained, leading to a large gap between the performance monitoring indicators calculated by the terminal and the actual performance monitoring indicators, resulting in inaccurate model performance monitoring indicators.

[0137] The incomplete Set A includes a subset of the complete Set A or a set of resources that represents Set A but has fewer reference signals than the complete Set A.

[0138] To address the aforementioned issues and resolve the problem of inaccurate performance monitoring parameters due to unreasonable configuration parameters in existing UE-side model performance monitoring, this application provides a Channel State Information (CSI) reporting method. This method involves configuring a CSI reporting configuration for the terminal, where each configuration includes multiple CSI resource sets. Alternatively, at least two CSI reporting configurations can be configured for the terminal, each including at least one CSI resource set. The terminal can obtain multiple CSI resource sets, which may include measurement resources with varying quantities. When applied to AI / ML model monitoring, these multiple CSI resource sets may include the complete Set A required by the AI / ML model for prediction, or they may include incomplete Sets. A. By ensuring a more reasonable set of configured CSI resources, the number of reference signals required for beam scanning can be reduced to some extent. In addition, by using the report results in the first CSI report associated with the CSI reporting configuration sent by the network device and the set of CSI resources used for measurement at multiple reference signal transmission times, the effective reference signal transmission time can be determined. Using the effective reference signal transmission time, a second CSI report can be obtained for monitoring and reporting AI / ML model performance, which can ensure the accuracy and reliability of the measurement resources for performance monitoring.

[0139] One embodiment of this application provides a channel state information reporting method, executed by a terminal, such as... Figure 2 As shown, the method includes:

[0140] S210, acquire at least one Channel State Information (CSI) reporting configuration sent by the network device; wherein, the CSI reporting configuration is one, and the CSI reporting configuration includes multiple CSI resource sets; or, the CSI reporting configuration is at least two, and each CSI reporting configuration includes at least one CSI resource set;

[0141] S220, determine the effective reference signal transmission timing based on the report results in the first CSI report associated with the CSI reporting configuration and the set of CSI resources used for measurement at multiple reference signal transmission timings;

[0142] S230, after measuring using the CSI resource set in the CSI reporting configuration, a second CSI report is obtained based on the measurement results of the CSI resource set in the CSI reporting configuration at the effective reference signal transmission time and the reporting results in the first CSI report;

[0143] S240, the second CSI report is sent to the network device.

[0144] In the channel state information reporting method described in this application embodiment, optionally, the CSI reporting configuration obtained by the terminal is used for UE-side AI / ML model inference monitoring. Channel environment measurement is performed according to the CSI resource set in the CSI reporting configuration sent by the network-side device. The obtained measurement results are associated with the CSI report (first CSI report) used for reporting the prediction results of the UE-side AI / ML model to obtain the CSI report (second CSI report) of the CSI reporting configuration, which is used to report the performance monitoring indicators of the AI / ML model.

[0145] In one embodiment of this application, optionally, the CSI reporting configuration is one, and at least one CSI resource set in the CSI resource set of the CSI reporting configuration includes a first resource set, and at least one CSI resource set includes a second resource set; or

[0146] The CSI reporting configuration is at least two, and the CSI resource set in at least one CSI reporting configuration includes a first resource set, and the CSI resource set in at least one CSI reporting configuration includes a second resource set;

[0147] The second resource set is different from the first resource set, and the number of resources included in the second resource set is less than the number of resources included in the first resource set.

[0148] In this embodiment of the application, the first resource set can be the predicted resource set of the AI / ML model on the UE side, that is, the predicted resource set predicted by the AI / ML model, i.e., the complete Set A; optionally, the second resource set can be a subset of the predicted resource set predicted by the AI / ML model, and the second resource set can be called an incomplete Set A; or, the number of CSI resources in the predicted resource set included in the second resource set is less than the number of CSI resource sets in the predicted resource set.

[0149] In one embodiment of this application, optionally, the terminal receives a CSI reporting configuration from a network-side device. At least one CSI resource set in this CSI reporting configuration includes a first resource set, i.e., the complete Set A. Optionally, other CSI resource sets in the CSI reporting configuration can be subsets of Set A. By employing this embodiment, the terminal obtains a CSI reporting configuration in which at least one CSI resource set includes the complete Set A, thereby improving the accuracy of effective reference signal transmission timing detection during channel measurement.

[0150] In one embodiment, optionally, the CSI reporting configuration obtained by the terminal (such as the first CSI reporting configuration) is associated with the first CSI report of another obtained CSI reporting configuration (such as the second CSI reporting configuration). The second CSI reporting configuration is a reporting configuration for triggering the UE-side model, that is, a CSI resource for configuring the UE to report model prediction results.

[0151] Optionally, the CSI reporting configuration (first CSI reporting configuration) obtained by the terminal for monitoring AI / ML model inference on the UE side includes the report identifier ID of the associated CSI reporting configuration (second CSI reporting configuration) for reporting model prediction results. Based on the report identifier ID, the first CSI report associated with the first CSI reporting configuration can be determined, that is, the prediction result of the AI / ML model on the UE side at the prediction time corresponding to the reference signal transmission time can be determined.

[0152] Furthermore, based on the reporting results of the first CSI report and the CSI resource set used for the reference signal transmission timing determined according to the first CSI reporting configuration, it is determined whether the corresponding reference signal transmission timing is a valid reference signal transmission timing. Specifically, the reporting timing of the first CSI report and the reference signal transmission timing determined by the first CSI reporting configuration satisfy the principle of closest time distance. Optionally, the associated reference signal transmission timing can be determined based on the reporting timing of the first CSI report as the transmission timing of the closest CSI reference signal determined by the first CSI reporting configuration; or, the associated reporting timing can be determined based on the transmission timing of the CSI reference signal determined by the first CSI reporting configuration as the reporting timing of the closest first CSI report.

[0153] For example, the UE predicts the Top-4 beam IDs of the 64 beams in Set A based on the RSRP of the 16 beams in Set B. That is, the prediction resource set of the AI / ML model on the UE side is Set A.

[0154] Specifically, the terminal receives the first CSI reporting configuration configured by the network device for monitoring the AI / ML model inference on the UE side, and receives the second CSI reporting configuration configured by the network for reporting the AI / ML model inference results on the UE side. The second CSI reporting configuration is a periodic reporting.

[0155] In this embodiment, optionally, the first CSI reporting configuration received by the terminal includes a report identifier ID for reporting the second CSI reporting configuration. Based on the report identifier ID, the first CSI report associated with the first CSI reporting configuration can be determined.

[0156] In this embodiment of the application, optionally, the CSI reporting configuration is one, and among the plurality of CSI resource sets, the configuration period of the CSI resource set including the first resource set is greater than or equal to the configuration period of the CSI resource set including the second resource set; and / or,

[0157] When there is temporal overlap between the CSI resource set including the first resource set and the CSI resource set including the second resource set, the CSI resources configured in the CSI resource set of the first resource set are resources for beam measurement.

[0158] In this embodiment of the present application, when the network-side device configures a CSI reporting configuration for the terminal, optionally, the configuration period of the CSI resource set including the first resource set is different from the configuration period of the CSI resource set including the second resource set. Specifically, the configuration period of the CSI resource set including the first resource set is greater than or equal to the configuration period of the CSI resource set including the second resource set; that is, the configuration period of the CSI resource set including the complete Set A is greater than or equal to the configuration period of the CSI resource set including the incomplete Set A. For example, the configuration period of the CSI resource set including the complete Set A is 160ms, and the configuration period of the CSI resource set including the incomplete Set A is 80ms.

[0159] In one implementation, optionally, when the configuration period of the CSI resource set including the first resource set is different from the configuration period of the CSI resource set including the second resource set, but the offset is the same, the transmission periods of the CSI resources in the CSI resource set including the first resource set and the CSI resources in the CSI resource set including the second resource set will overlap in the time domain. In this case, it is determined that the transmission priority of the reference signal in the CSI resource set including the first resource set is higher than the transmission priority of the reference signal in the CSI resource set including the second resource set; in other words, the CSI resource with a larger number of CSI resources has the highest priority. That is, when there is time domain overlap between the CSI resource set including the first resource set and the CSI resource set including the second resource set, the CSI resources configured in the CSI resource set of the first resource set are determined to be resources used for beam measurement.

[0160] Optionally, in this embodiment of the application, when the terminal receives only one CSI report sent by the network device, in step S220, when determining the effective reference signal transmission timing, the determined effective reference signal transmission timing is: the CSI resource identifier ID in the report result of the first CSI report associated with the effective reference signal transmission timing belongs to the CSI resource ID in the CSI resource set measured during the effective reference signal transmission timing; or

[0161] The CSI resource ID in the report result of the first CSI report associated with the effective reference signal transmission timing is an associated CSI resource ID belonging to the set of CSI resource IDs measured during the effective reference signal transmission timing; or

[0162] At least a portion of the CSI resource identifier IDs in the report results of the first CSI report associated with the effective reference signal transmission timing belong to the CSI resource IDs in the CSI resource set measured during the effective reference signal transmission timing; or

[0163] At least a portion of the CSI resource identifier ID in the report results of the first CSI report associated with the effective reference signal transmission timing is an associated CSI resource ID belonging to the set of CSI resource IDs measured during the effective reference signal transmission timing.

[0164] Optionally, the network device can configure the association between CSI resources used for UE-side AI / ML model prediction and CSI resources used for UE-side AI / ML model monitoring. For example, the beam IDs of the prediction beams used for UE-side AI / ML model prediction include RS ID=1, RS ID=2, and RS ID=3, and the beam IDs of the CSI resources used for UE-side AI / ML model monitoring include RS ID=4, RS ID=5, RS ID=6, and RS ID=7. The network device can configure the association between the prediction beams used for UE-side AI / ML model prediction and the CSI resources used for UE-side AI / ML model monitoring: RS ID=1 of the prediction beam corresponds to monitoring beam RS ID=4, RS ID=2 corresponds to monitoring beam RS ID=5, and RS ID=3 corresponds to monitoring beam RS ID=6. Based on this configured association, it can be used to determine the timing of effective reference signal transmission.

[0165] In step S220, based on the reporting results in the first CSI report associated with the CSI reporting configuration and the set of CSI resources used for measurements at multiple reference signal transmission times, a valid reference signal transmission time is determined, including one or more of the following:

[0166] If the CSI resource ID in the report result of the first CSI report associated with the reference signal transmission timing belongs to the CSI resource ID in the CSI resource set measured at the corresponding reference signal transmission timing, then the reference signal transmission timing is determined to be a valid reference signal transmission timing.

[0167] The report result of the first CSI report associated with the reference signal transmission timing is also the Top-K predicted beam. For example, when the CSI resource ID (i.e., beam ID) in the report result of the first CSI report is {4, 5, 6, 7}, and the CSI resource ID (i.e., beam ID) in the CSI resource set measured at the corresponding reference signal transmission timing is {1, 2, 3…16}, then the reference signal transmission timing is determined to be a valid reference signal transmission timing. When the CSI resource ID (i.e., beam ID) in the report result of the first CSI report is {15, 16, 17, 18}, and the CSI resource ID (i.e., beam ID) in the CSI resource set measured at the corresponding reference signal transmission timing is {1, 2, 3…16}, then the corresponding reference signal transmission timing is determined to be not a valid reference signal transmission timing.

[0168] If the CSI resource ID in the report result of the first CSI report associated with the reference signal transmission timing belongs to the associated CSI resource ID in the CSI resource set measured at that reference signal transmission timing, then the reference signal transmission timing is determined to be a valid reference signal transmission timing.

[0169] If at least a portion of the CSI resource identifier IDs in the report results of the first CSI report associated with the reference signal transmission timing belong to the CSI resource IDs in the set of CSI resources measured at the corresponding reference signal transmission timing, then the reference signal transmission timing is determined to be a valid reference signal transmission timing.

[0170] Optionally, the at least partial CSI resource ID includes one of the following:

[0171] The CSI resource IDs of the N CSI resources with the highest channel quality in the report results;

[0172] The CSI resource IDs of the N CSI resources with the highest predicted probability in the report results;

[0173] The CSI resource IDs of any N CSI resources in the report results;

[0174] Where N is an integer greater than or equal to 1, and N is less than the number of CSI resources in the report results.

[0175] In this implementation, if at least a portion of the CSI resource identifiers (IDs) in the report results of the first CSI report associated with the reference signal transmission timing belong to the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing, then the reference signal transmission timing is considered a valid reference signal transmission timing. Here, a portion of the CSI resource IDs are N CSI resource IDs from the Top-K beam IDs predicted by the UE model, where N is less than K.

[0176] For example, when the UE-side model is a regression model, the output of the UE-side model is the Top-4 beam IDs and L1-RSRP. Part of the CSI resource IDs are also partial beam IDs from the Top-4 beam IDs, such as the N=2 beams with the highest predicted L1-RSRP. For instance, if the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing are beam IDs {1, 2, 3…16}, and if the UE-side model predicts the Top-4 beams according to L1-RSRP from high to low as beam IDs {15, 16, 17, 18}, then because the two beams with the highest predicted L1-RSRP are 15 and 16, which belong to the beam IDs in the CSI resource set measured during this reference signal transmission timing, this reference signal transmission timing is determined to be a valid reference signal transmission timing.

[0177] When the UE-side model is a classification model, the output of the UE-side model is the Top-4 beam IDs. Some CSI resource IDs can be the two beam IDs with the highest predicted probability among the Top-4 beam IDs. For example, if the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing are beam IDs, and the beam IDs are {1, 2, 3…16}, and if the beam IDs predicted by the UE-side model are sorted from high to low probability as {8, 9, 17, 18}, then the beam IDs with the highest probability, 8 and 9, belong to the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing, and thus the reference signal transmission timing is determined to be a valid reference signal transmission timing. If the beam IDs predicted by the UE-side model are sorted from high to low probability as {17, 18, 8, 9}, then since beam IDs 17 and 18 do not belong to the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing, then the reference signal transmission timing is determined to be not a valid reference signal transmission timing.

[0178] In another implementation, when the UE-side model is a classification model, the output of the UE-side model is the Top-4 beam IDs, and some CSI resource IDs can be any two beams from the Top-4 beam IDs. For example, if the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing are beam IDs, and the beam IDs are {1, 2, 3…16}, and if the beam IDs predicted by the UE-side model are sorted from high to low probability as {17, 18, 8, 9}, since 8 and 9 in the predicted beam IDs belong to the CSI resource IDs in the CSI resource set measured during the reference signal transmission timing, then the reference signal transmission timing is determined to be a valid reference signal transmission timing.

[0179] In this embodiment of the application, the determination of the effective reference signal transmission timing can optionally be achieved by network device configuration, protocol agreement, or terminal implementation. If the determination is based on UE implementation, the terminal needs to report relevant information about the effective reference signal transmission timing, including the number of effective reference signal transmission timings, the proportion of effective reference signal transmission timings to total reference signal transmission timings, and / or time-related information of the reference signal transmission timings.

[0180] Optionally, in this embodiment of the application, when the CSI reporting configuration is set to one, the second CSI report determined by the terminal includes first information and / or second information;

[0181] The first information includes a first indicator, which is used to indicate the comparison result between the measurement results of the plurality of CSI resource sets in the CSI reporting configuration at the effective reference signal transmission time and the corresponding report results;

[0182] The second information includes a plurality of second indicators, each of which is used to indicate the comparison result of the measurement result of one of the CSI resource sets in the CSI reporting configuration at the effective reference signal transmission time with the corresponding report result.

[0183] In this implementation, the terminal determines the second CSI report to be reported based on the measurement results of the effective reference signal transmission timing, according to the CSI reporting configuration configured by the network device.

[0184] In one implementation, the second CSI report determined by the terminal includes first information, which includes a first indicator. This first indicator is determined based on the measurement results of the CSI resource set for all valid reference signal transmission opportunities. Figure 3For example, if we set the number of reference signal transmission opportunities determined by the CSI reporting configuration to be 5, and the first 4 reference signal transmission opportunities are defined as valid reference signal transmission opportunities by the UE, then the terminal determines the performance monitoring status of each reference signal transmission opportunity based on the actual measurement results of the first 4 reference signal transmission opportunities and the reported results in the associated first CSI report, and calculates the first index. Optionally, the first index is determined based on the comparison between the actual measurement results of each valid reference signal transmission opportunity and the reported results in the associated first CSI report. For example, if the actual measurement results of each valid reference signal transmission opportunity are the same as the reported results in the associated first CSI report, the terminal considers the model monitoring result of that valid reference signal transmission opportunity to be correct and records it as 1; otherwise, it records it as 0. In this way, the terminal can report the first index based on the monitoring results of multiple CSI resource sets from valid reference signal transmission opportunity 1 to valid reference signal transmission opportunity 4; optionally, the first index can be used to indicate the percentage of monitoring that is a correct prediction in the valid monitoring time, or the number of monitoring that is a correct prediction.

[0185] In another implementation, the second CSI report includes second information, which includes multiple second indicators. Each second indicator is used to indicate the comparison result between the measurement result of one of the CSI resource sets in the CSI reporting configuration at the valid reference signal transmission time and the corresponding report result. For example, if there are 5 reference signal transmission times determined according to the CSI reporting configuration, and the first 4 reference signal transmission times are determined to be valid reference signal transmission times by the UE, then the terminal determines the performance monitoring status of each reference signal transmission time based on the actual measurement results of the first 4 reference signal transmission times and the report results in the associated first CSI report. For each valid reference signal transmission time corresponding to the first 4 reference signal transmission times, a second indicator is determined. Optionally, each second indicator is used to indicate the comparison result between the actual measurement of the corresponding valid reference signal transmission time and the report result in the associated first CSI report. For example, if the actual measurement result of the valid reference signal transmission time is the same as the report result in the associated first CSI report, the terminal considers the model monitoring result of that valid reference signal transmission time to be correct, and the corresponding second indicator is set to 1; otherwise, the corresponding second indicator is set to 0.

[0186] In another embodiment, optionally, the CSI reporting configuration is one, and at least one CSI resource set in the CSI resource set of the CSI reporting configuration includes a first resource set, at least one CSI resource set includes a second resource set, and the second CSI report includes third information;

[0187] The third information includes a third indicator and / or a fourth indicator. The third indicator is used to indicate the comparison result between the measurement result of the CSI resource set including the first resource set in the CSI reporting configuration at the effective reference signal transmission time and the corresponding report result. The fourth indicator is used to indicate the comparison result between the measurement result of the CSI resource set including the second resource set in the CSI reporting configuration at the effective reference signal transmission time and the corresponding report result.

[0188] Using this implementation method, the terminal can determine the third indicator based on the first resource set (complete SetA) in the CSI reporting configuration and the fourth indicator based on the second resource set (incomplete SetA) in the CSI reporting configuration.

[0189] For example, in Figure 3 The first four reference signal transmission opportunities are valid reference signal transmission opportunities. Among them, transmission opportunity 3 is a valid reference signal transmission opportunity measured with a complete SetA; valid reference signal transmission opportunities 1, 2, and 4 are valid reference signal transmission opportunities measured with a non-complete SetA. The terminal compares the measurement result and prediction result of valid reference signal transmission opportunity 3 to calculate the third index; the terminal compares the measurement results of valid reference signal transmission opportunities 1, 2, and 4 with the associated prediction results to obtain the fourth index.

[0190] Using this implementation method, the third indicator can be used to report the performance monitoring results of the UE model measured with the complete SetA to the network device, and the fourth indicator can be used to report the performance monitoring results of the UE model measured with the incomplete SetA to the network device.

[0191] In another embodiment of this application, in step S210, the obtained CSI reporting configuration is at least two, and the CSI resource set in at least one CSI reporting configuration includes a first resource set, and the CSI resource set in at least one CSI reporting configuration includes a second resource set;

[0192] The second resource set is different from the first resource set, and the number of resources included in the second resource set is less than the number of resources included in the first resource set.

[0193] Similar to the previous implementation, in this implementation, the first resource set can be the predicted resource set of the AI / ML model on the UE side, that is, the predicted resource set predicted by the AI / ML model, i.e., the complete Set A; optionally, the second resource set can be a subset of the predicted resource set predicted by the AI / ML model, and the second resource set can be called an incomplete Set A; or, the number of CSI resources in the predicted resource set included in the second resource set is less than the number of CSI resource sets in the predicted resource set.

[0194] In this implementation, the terminal obtains at least two CSI reporting configurations for AI / ML model monitoring. The at least one CSI reporting configuration includes a complete Set A, which improves the accuracy of detecting the effective reference signal transmission timing during channel measurement.

[0195] Optionally, in this embodiment of the application, at least two CSI reporting configurations obtained by the terminal for AI / ML model monitoring are associated with another obtained CSI reporting configuration, which is a reporting configuration for triggering the UE-side model, that is, a CSI resource for configuring the UE to report model prediction results.

[0196] Optionally, the at least two CSI reporting configurations obtained by the terminal for AI / ML model monitoring each include the report identifier ID of the associated CSI reporting configuration for reporting model prediction results. The first CSI report associated with the at least two CSI reporting configurations can be determined based on the report identifier ID.

[0197] For example, the terminal receives a first CSI reporting configuration sent by the network device. This first CSI reporting configuration includes a complete Set A, wherein the first CSI reporting configuration is associated with the ID of a second CSI reporting configuration and is used to monitor the inference accuracy of the terminal-side AI / ML model associated with the second CSI reporting configuration. Additionally, the terminal also receives a third CSI reporting configuration sent by the network device. This third CSI reporting configuration includes an incomplete Set A, wherein the third CSI reporting configuration is associated with the ID of the second CSI reporting configuration and is also used to monitor the inference accuracy of the terminal-side AI / ML model associated with the second CSI reporting configuration.

[0198] Optionally, the first CSI reporting configuration and the third CSI reporting configuration mentioned above each include the report identifier ID of the associated second CSI reporting configuration. Based on the first CSI report, the report results corresponding to measurements performed on multiple reference signal transmission times using the CSI resource set configured with the CSI reporting configuration can be determined, that is, the prediction result of the UE at the prediction time corresponding to the reference signal transmission time can be determined. The prediction result is compared with the report result at the corresponding reference signal transmission time to obtain the performance monitoring index of the UE-side model.

[0199] For example, the UE predicts the Top-4 beam IDs of the 64 beams in Set A based on the RSRP of the 16 beams in Set B. That is, the prediction resource set of the AI / ML model on the UE side is Set A.

[0200] Specifically, the periodic CSI reporting configuration #1 configured by the terminal receiving network device is used to trigger the aforementioned AI / ML model on the UE side; the CSI reporting configuration #2 configured by the receiving network device is used to monitor the AI / ML model, and the complete SetA beam is configured in CSI reporting configuration #2; the CSI reporting configuration #3 configured by the receiving network device is used to monitor the AI / ML model, and the non-SetA beam set is configured in CSI reporting configuration #3, such as a subset of the SetA beam set. Figure 4 As shown.

[0201] In this embodiment, optionally, the terminal receives the configuration ID of the periodic CSI reporting configuration #1 configured by the network device as 1. Using this embodiment, the terminal receives CSI reporting configuration #2 sent by the network device, where CSI reporting configuration #2 is configured or associated with CSI reporting configuration ID = 1, used to monitor the UE-side AI / ML model triggered by CSI reporting configuration #1; and receives CSI reporting configuration #3 sent by the network device, where CSI reporting configuration #3 is configured or associated with CSI reporting configuration ID = 1, used to monitor the UE-side AI / ML model triggered by CSI reporting configuration #1. Based on this configuration, the terminal can determine that the monitoring resource set in CSI reporting configuration #2 is a complete SetA.

[0202] In this embodiment, the terminal obtains at least two CSI reporting configurations for AI / ML model monitoring. In step S220, the terminal determines the specific implementation of the effective reference signal transmission timing based on the report results in the first CSI report associated with the CSI reporting configuration and the set of CSI resources used for measurement at multiple reference signal transmission timings. This implementation is the same as the implementation when the terminal obtains only one CSI reporting configuration for AI / ML model monitoring, and will not be described again here.

[0203] In this embodiment of the present application, when the CSI reporting configuration is at least two, in step S230, the obtained second CSI report includes third information;

[0204] The third information includes at least one indicator, each indicator corresponding to a CSI reporting configuration, used to indicate the comparison results of the measurement results of the plurality of CSI resource sets in the corresponding CSI reporting configuration at the effective reference signal transmission time with the reporting results in the corresponding first CSI report.

[0205] Using this implementation, the terminal can determine the information reported in the second CSI report based on the effective reference signal transmission timing determined by one or more of the at least two CSI reporting configurations.

[0206] Optionally, the CSI reporting configuration is at least two. The CSI resource set in the first CSI reporting configuration of the at least two CSI reporting configurations includes a first resource set, and the CSI resource set in the second CSI reporting configuration of the at least two CSI reporting configurations includes a second resource set. The number of resources included in the second resource set is less than the number of resources included in the first resource set. At least one indicator in the third information in the second CSI report includes a fifth indicator corresponding to the first CSI reporting configuration, and / or includes a sixth indicator corresponding to the second CSI reporting configuration.

[0207] For example, combining Figure 4 As shown, the terminal obtains the third information in the second CSI report by comparing the measurement results of multiple CSI resource sets in CSI reporting configuration #2 at the effective reference signal transmission time with the corresponding report results in the first CSI report, that is, obtains the fifth indicator of the corresponding CSI reporting configuration (first CSI reporting configuration); and / or, the terminal obtains the third information in the second CSI report by comparing the measurement results of multiple CSI resource sets in CSI reporting configuration #3 at the effective reference signal transmission time with the corresponding report results in the first CSI report, that is, obtains the sixth indicator of the corresponding CSI reporting configuration (second CSI reporting configuration).

[0208] In this embodiment, optionally, the terminal determines third information based on the effective reference signal transmission timing of multiple CSI resource sets within a preset monitoring window. For example, the terminal obtains a fifth indicator by comparing the measurement results of multiple CSI resource sets in CSI reporting configuration #2 at the effective reference signal transmission timing determined by the preset monitoring window with the corresponding reporting results in the first CSI report; and / or, obtains a sixth indicator by comparing the measurement results of multiple CSI resource sets in CSI reporting configuration #3 at the effective reference signal transmission timing determined by the preset monitoring window with the corresponding reporting results in the first CSI report.

[0209] Optionally, in this embodiment of the application, the second CSI report may further include one or more of the following:

[0210] The difference between the fifth indicator and the sixth indicator;

[0211] The fourth piece of information is used to indicate whether the absolute value of the difference between the fifth indicator and the sixth indicator is greater than or equal to a preset threshold.

[0212] Optionally, when the fifth indicator mentioned above is obtained, the method further includes:

[0213] Send a second CSI report to the network device based on one or more of the following methods:

[0214] RRC configuration;

[0215] First event.

[0216] The reporting method configured in RRC can be one or more of the following: periodic reporting, non-periodic reporting, and semi-periodic reporting.

[0217] Optionally, the first event includes one or more of the following:

[0218] The fifth indicator is different from the sixth indicator;

[0219] The absolute value of the difference between the fifth indicator and the sixth indicator is greater than or equal to a preset threshold.

[0220] Specifically, when a second CSI report is sent to the network device based on the first event, the second CSI report is sent to the network device if the first event is satisfied.

[0221] Optionally, when the sixth indicator mentioned above is obtained, the method further includes:

[0222] Based on the RRC configuration, a second CSI report is sent to the network device.

[0223] The reporting method configured in this RRC can be one or more of the following: periodic reporting, non-periodic reporting, and semi-periodic reporting.

[0224] In this embodiment, a fifth indicator is determined based on a first CSI reporting configuration including a complete SetA, and a sixth indicator is determined based on a second CSI reporting configuration including an incomplete SetA. A second CSI report is sent to the network device when a first event is met.
