[0088] In some embodiments, beamforming has wide applications in multiple fields. For example, in new radio (NR), especially when the communication frequency range (FR) is at FR2, beam-based transmission and reception are required to ensure coverage due to the rapid attenuation of high-frequency channels. As another example, radar systems use beams to scan for objects in the air or at sea. And in the field of acoustics, beamforming technology is used to adjust the direction of sound propagation, etc., and these are just a few examples.

[0089] It is understood that the embodiments of this disclosure are introduced and described using the scenario of "using beam-based transmission and reception in a new air interface" as an example, but the solutions of each embodiment can be applied to other beam-related scenarios, and this disclosure does not limit them.

[0090] In traditional beam management, the base station configures a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set and then reports the identifiers (IDs) of the X strongest reference signal resources, along with their corresponding Layer 1 reference signal received power (L1-RSRP) and / or Layer 1 signal-to-interference-plus-noise ratio (L1-SINR). The problem with this traditional method is that the base station's set contains M reference signal resources, each corresponding to a different transmitted beam. Therefore, for each reference signal resource, the terminal needs to use all received beams to measure it, obtain the beam measurement quality for each received beam, and determine the optimal beam measurement quality. Thus, the number of beam pairs the terminal needs to measure is M*N, where M is the number of transmitted beams from the base station and N is the number of received beams from the terminal.

[0091] In some embodiments, to reduce the number of beam pairs measured by the terminal, an AI-based prediction method is proposed. For example, if the terminal originally needed to measure M*N beam pairs (where M is the number of beams transmitted by the base station and N is the number of beams received by the terminal) or M transmitted beams, with the help of an Artificial Intelligence (AI) model, for spatial beam prediction, the terminal only needs to measure a portion of the M*N beam pairs or M transmitted beams, such as 1 / 8 or 1 / 4. Then, the beam measurement quality corresponding to these measured beam pairs or transmitted beams is input into the AI ​​model, and the model can output the beam information of the M*N beam pairs or M transmitted beams. For temporal beam prediction, the terminal can measure the beam quality of beam pairs or transmitted beams at historical times to predict the beam information of beam pairs or transmitted beams at future times.

[0092] In some embodiments, AI-based beam measurement prediction includes spatial beam prediction: predicting the measurement results of beams in set A (set A) based on the measurement results of beams in set B (set B). It also includes temporal beam prediction: predicting the beam of set A in future times based on the measurement results of set B in historical time. Here, set B is a subset of set A (the beams contained in set B are a part of set A), or set B is a wide beam while set A is a narrow beam, or the temporal beam prediction may also include a case where set B and set A are the same.

[0093] In some embodiments, the beam prediction principle based on the AI ​​model is as follows:

[0094] For spatial prediction: The L1-RSRP (which may also include beam or beam pair IDs) of the terminal measurement set B is input into the AI ​​model to predict the L1-RSRP of set A and / or the optimal beam ID of set A. The relationship between set B and set A includes the following two types:

[0095] First, set B is a subset of set A. For example, if set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction), then set B contains N of those reference signal resources, such as N=8. The above only considers the transmit beams. If beam pairs are considered, the terminal's receive beams also need to be taken into account. For example, if there are 32 transmit beams and the terminal has 4 receive beams, then set A would have 32*4 beam pairs; set B could have 32 beam pairs, 16 beam pairs, etc. Here, * stands for multiplication.

[0096] Second, set B has a wide beam, while set A has a narrow beam. For example, set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction, and the 32 reference signals cover a 120-degree direction). Set B contains another N reference signal resources, for example, N=8, and these N reference signals also cover a 120-degree direction. That is, the beam direction of each reference signal in set B covers the beam directions of multiple reference signal resources in set A. This can be understood as the 32 / N reference signal resources in set A and the same reference signal resource in set B having a quasi-co-location (QCL) type (Type D) relationship.

[0097] For time-domain prediction, the terminal measures the L1-RSRP of historical time set B, inputs it into the AI ​​model, and predicts the L1-RSRP of future time set A. Besides the two relationships mentioned above, there is another possibility: set B and set A are the same. In the case of AI model-based prediction, the reference signal resources for future time moments do not need to be transmitted; the beam information is obtained based on the AI ​​model output and reported to the base station. However, in the traditional method, the reference signal resources for future time moments also need to be transmitted; the terminal measures the reference signal resources for future time moments, obtains the beam information, and reports it to the base station.

[0098] In some embodiments, AI or machine learning (ML) functions or models can be managed based on performance monitoring. For example, monitoring whether the performance of a function or model meets a threshold; if it does not, it can be deactivated; if it does, it can be activated. The performance monitoring metric could be beam accuracy.

[0099] However, determining the accuracy of the beam is a problem that needs to be solved.

[0100] Therefore, this disclosure provides a communication method in which a terminal receives first information, the first information including a first Channel State Information (CSI) report configuration identifier, so that the terminal can determine the first CSI report configuration information corresponding to the first CSI report configuration identifier. The first information also includes a second CSI report configuration identifier, so that the terminal can determine the second CSI report configuration information corresponding to the second CSI report configuration identifier. The first CSI report configuration information and the second CSI report configuration information are used to determine beam accuracy indication information, that is, to determine beam accuracy, thereby improving communication efficiency.

[0101] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0102] In step S2101, network device 102 sends first information to terminal 101.

[0103] In some embodiments, terminal 101 receives first information sent by network device 102.

[0104] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0105] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0106] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0107] In some embodiments, the first information includes a first CSI report configuration identifier and a second CSI report configuration identifier. The first CSI report configuration identifier corresponds to first CSI report configuration information, and the second CSI report configuration identifier corresponds to second CSI report configuration information associated with the first CSI report configuration identifier. The first CSI report configuration information and the second CSI report configuration information are used to determine beam accuracy indication information.

[0108] In some embodiments, the first information includes the first CSI report configuration information corresponding to the first CSI report configuration identifier.

[0109] In some embodiments, the second CSI report configuration identifier may also correspond to the second CSI report configuration information associated with the first CSI report configuration information, or the second CSI report configuration identifier may also correspond to the second CSI report configuration information associated with the first CSI report configuration.

[0110] In some embodiments, beam accuracy indication information may also be referred to as beam accuracy or beam accuracy indication. The above descriptions may be used interchangeably and are not limited in this disclosure.

[0111] In some embodiments, the first information may also be referred to as CSI reportconfig information, and this disclosure does not limit the name of the first information.

[0112] In some embodiments, the network device may send first CSI report configuration information and second CSI report configuration information to the terminal. The first CSI report configuration information can be used for model performance monitoring to obtain beam measurement results, and the second CSI report configuration information can be used for model derivation to obtain beam prediction results. The terminal can determine beam accuracy indication information by comparing the beam measurement results and the beam prediction results. The first CSI report configuration information may also be referred to as first configuration information, and the second CSI report configuration information may also be referred to as second configuration information. This disclosure does not limit the names of the first CSI report configuration information and the second CSI report configuration information.

[0113] Optionally, the first information includes first CSI report configuration information, which includes a first CSI report configuration identifier and a first reference signal resource set. The first information or the first CSI report configuration information also includes a second CSI report configuration identifier. The second CSI report configuration information may be included in other information different from the first information, wherein the second CSI report configuration information includes a second CSI report configuration identifier and a second reference signal resource set. The second CSI report configuration information can also be used to determine a third reference signal resource set. Based on the second CSI report configuration information, the terminal measures the measurement results of the second reference signal resource set and inputs them into the AI / ML model to obtain the beam prediction results corresponding to the third reference signal resource set. Based on the first CSI report configuration information, the terminal measures the beam measurement results of the first reference signal resource set. Based on the beam measurement results of the first reference signal resource set and the beam prediction results of the third reference signal resource set, the terminal determines beam accuracy indication information.

[0114] Optionally, the purpose of the first CSI report configuration identifier and the second CSI report configuration identifier is to facilitate the inclusion of identifiers in the CSI report when the terminal submits the report. If the submitted CSI report includes the first CSI report configuration identifier, it informs the network device that the CSI report corresponds to the first CSI report configuration information. If the CSI report includes the second CSI report configuration identifier, it informs the network device that the CSI report corresponds to the second CSI report configuration information.

[0115] Optionally, the network device may pre-configure first CSI report configuration information and second CSI report configuration information, wherein the first information contains only a first CSI report configuration identifier and a second CSI report configuration identifier. The terminal can determine the first CSI report configuration information from the pre-configured CSI report configuration information of the network device based on the first CSI report configuration identifier in the first information, and can determine the second CSI report configuration information from the pre-configured CSI report configuration information of the network device based on the second CSI report configuration identifier in the first information. The first CSI report configuration information includes a first set of reference signal resources, and the second CSI report configuration information includes a second set of reference signal resources.

[0116] It is understood that, in the various embodiments of this disclosure, when the CSI report configuration information is not preceded by "first," "second," or "third," it can refer to at least one of the first, second, and third CSI report configuration information, including but not limited to. Similarly, when the CSI report configuration identifier is not preceded by "first," "second," or "third," it can refer to at least one of the first, second, and third CSI report configuration identifiers, including but not limited to.

[0117] In some embodiments, beam accuracy indication information can be determined in the following manner: the terminal determines the beam prediction result corresponding to the third reference signal resource set based on the measurement results of the prediction model and the second reference signal resource set; the terminal determines the beam measurement result corresponding to the first reference signal resource set based on the measurement results of the first reference signal resource set; the terminal determines the beam accuracy indication information based on the beam prediction result of the third reference signal resource set and the beam measurement result of the first reference signal resource set; wherein, the first reference signal resource set is a subset of the third reference signal resource set, including, the first reference signal resource set is a proper subset of the third reference signal resource set or the first reference signal resource set is the same as the third reference signal resource set.

[0118] In some embodiments, beam results may include beam measurement results and beam prediction results. Beam measurement results refer to beam results obtained based on actual measurements, while beam prediction results refer to beam results derived from a prediction model. Beam results may include an identifier of at least one optimal beam, and / or, the L1-RSRP of at least one beam. Beam measurement results may include an identifier of at least one optimal beam obtained through actual measurement, and / or, the L1-RSRP of at least one measured beam. Beam prediction results may include an identifier of at least one optimal beam predicted by the model, and / or, the L1-RSRP of at least one beam predicted by the model. "L1-RSRP" may also be replaced with "L1-SINR" or "L1-RSRP and L1-SINR," etc., and this disclosure is not limited thereto. Comparing beam measurement results and beam prediction results can yield beam accuracy indication information.

[0119] For example, the terminal can input the measurement results of the second reference signal resource set into the prediction model, and the prediction model can output the beam prediction results corresponding to the third reference signal resource set.

[0120] For example, the terminal can determine the beam measurement results corresponding to the first reference signal resource set based on the measurement results of the first reference signal resource set. For instance, suppose the first reference signal resource set includes reference signal resource A, reference signal resource B, and reference signal resource C. Measuring the reference signal on reference signal resource A yields the measurement result for reference signal resource A, let's say L1-RSRP a. The measurement result for reference signal resource B is L1-RSRP b, and the measurement result for reference signal resource C is L1-RSRP c. Therefore, the measurement results of the first reference signal resource set include L1-RSRP a, L1-RSRP b, and L1-RSRP c. There is a correspondence between reference signal resources and beams. For example, reference signal resource A corresponds to beam 1, reference signal resource B corresponds to beam 2, and reference signal resource C corresponds to beam 3. If L1-RSRP a > L1-RSRP b > L1-RSRP c, then the beam quality of beam 1 is higher than that of beam 2, and the beam quality of beam 2 is higher than that of beam 3. The optimal beam can be beam 1, or the optimal two beams can be beam 1 and beam 2. The beam measurement result corresponding to the first reference signal resource set may include the identifier of beam 1, and / or at least one of L1-RSRP a, L1-RSRP b, and L1-RSRP c. Alternatively, the beam measurement result may include the identifiers of beam 1 and beam 2, and / or at least one of L1-RSRP a, L1-RSRP b, and L1-RSRP c. Of course, the examples of reference signal resources A, B, and C, beams 1, 2, and 3, and L1-RSRPa, L1-RSRP b, and L1-RSRP c in this embodiment are exemplary and this disclosure is not limited thereto.

[0121] For example, by comparing the beam measurement results corresponding to the first reference signal resource set and the beam prediction results corresponding to the third reference signal resource set, beam accuracy indication information can be obtained. Here, the first reference signal resource set is a subset of the third reference signal resource set. It can be understood that the first reference signal resource set may be included within the third reference signal resource set, or the first and third reference signal resource sets may be the same; in either case, the first reference signal resource set is considered a subset of the third reference signal resource set.

[0122] For example, if the first reference signal resource set is included within the third reference signal resource set, but the first and third reference signal resource sets are different (i.e., the first reference signal resource set is a proper subset of the third reference signal resource set), then when the reference signal resource corresponding to the predicted optimal beam is within the first reference signal resource set, the beam prediction result corresponding to the third reference signal resource set and the beam measurement result corresponding to the first reference signal resource set can be used to determine beam accuracy indication information. For example, beam accuracy indication information can be determined based on L1-RSRP. Conversely, if the reference signal resource corresponding to the predicted optimal beam is not within the first reference signal resource set, then the beam prediction result corresponding to the third reference signal resource set and the beam measurement result corresponding to the first reference signal resource set may not be used to determine beam accuracy indication information. It is understood that the reference signal resource corresponding to the predicted optimal beam is a reference signal resource within the third reference signal resource set. The first reference signal resource set is a proper subset of the third reference signal resource set, meaning that the third reference signal resource set includes two parts: one part consists of all reference signal resources in the first reference signal resource set, and the other part consists of reference signal resources not included in the first reference signal resource set. When the reference signal resource corresponding to the predicted optimal beam is the latter, i.e., the reference signal resource is not in the first reference signal resource set, the beam prediction result corresponding to the third reference signal resource set and the beam measurement result corresponding to the first reference signal resource set may not be used to determine the beam accuracy indication information. Alternatively, the beam accuracy indication information can be determined based on the L1-RSRP of the predicted non-optimal beam. For example, if reference signal resource #a is included in both the first and third reference signal resource sets, and its measured L1-RSRP and predicted L1-RSRP have been obtained, although the beam corresponding to reference signal resource #a is not one of the K best measured or predicted beams, the beam accuracy indication information can still be determined based on the measured L1-RSRP and predicted L1-RSRP of reference signal resource #a, where K is greater than or equal to 1.

[0123] For example, if the first reference signal resource set and the third reference signal resource set are the same, the beam accuracy indication information can be determined based on the measurement results and prediction results each time.

[0124] In some embodiments, the beam accuracy indication information includes at least one of the following:

[0125] Does the predicted optimal beam include the measured optimal beam?

[0126] The proportion of predicted optimal beams that include the measured optimal beams out of the total number of predictions.

[0127] Whether the predicted optimal beam is included in the measured optimal beam.

[0128] The proportion of the number of times the predicted optimal beam is included in the measured optimal beam out of the total number of predictions.

[0129] The difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the measured optimal beam.

[0130] The proportion of the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the measured optimal beam within a threshold value.

[0131] The difference between the predicted L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the predicted optimal beam.

[0132] The proportion of the difference between the predicted L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the predicted optimal beam within a threshold value.

[0133] The predicted optimal beam is the optimal beam in the beam prediction results corresponding to the third reference signal resource set. The measured optimal beam is the optimal beam in the beam measurement results corresponding to the first reference signal resource set. For ease of description, this disclosure refers to them as the predicted optimal beam and the measured optimal beam, respectively.

[0134] Specifically, for the predicted optimal beam, its corresponding L1-RSRP can include both the measured L1-RSRP and the predicted L1-RSRP. For example, the L1-RSRP obtained by measuring the reference signal on the reference signal resource corresponding to the predicted optimal beam is the measured L1-RSRP, referred to as the measured L1-RSRP in this embodiment. Alternatively, the prediction model can output both the optimal beam and its corresponding L1-RSRP simultaneously, or obtain the L1-RSRP through other models; this disclosure refers to this as the predicted L1-RSRP.

[0135] The statement "the proportion of times the predicted optimal beam includes the measured optimal beam out of the total number of predictions" can be replaced with "the proportion of times the predicted optimal beam does not include the measured optimal beam out of the total number of predictions," or both can serve as indicators of beam accuracy. Similarly, the statement "the proportion of times the predicted optimal beam is included in the measured optimal beam out of the total number of predictions" can be replaced with "the proportion of times the predicted optimal beam is not included in the measured optimal beam out of the total number of predictions," or both can serve as indicators of beam accuracy.

[0136] It is understood that the predicted optimal beams in this invention may include K1 optimal beams, where K1 is greater than or equal to 1. The measured optimal beams may include K2 optimal beams, where K2 is greater than or equal to 1, and the values ​​of K1 and K2 may be the same or different.

[0137] In some embodiments, the first set of reference signal resources is included within the third set of reference signal resources, but the first set of reference signal resources and the third set of reference signal resources are different; that is, the first set of reference signal resources is a proper subset of the third set of reference signal resources. Assume that the first set of reference signal resources includes reference signal resources 1, 2, and 3, and the third set of reference signal resources includes reference signal resources 1, 2, 3, 4, 5, and 6.

[0138] Optionally, when the beam accuracy indication information is "whether the predicted optimal beam includes the measured optimal beam" or "whether the predicted optimal beam is included in the measured optimal beam", the beam accuracy information is determined if the predicted optimal beam corresponds to at least one of the reference signal resources 1, 2, and 3. If the predicted optimal beam and the measured optimal beam are different, the beam accuracy information is 'No'. For example, if the predicted optimal beam is beam 1 and the measured optimal beam is beam 2, the beam accuracy indication information is 'No'. It is understood that beam 1 here refers to the beam corresponding to reference signal resource 1, and beam 2 refers to the beam corresponding to reference signal resource 2. This disclosure simplifies for ease of description, and the rest are similar. If the predicted optimal beam and the measured optimal beam are partially the same, the beam accuracy information can be 'Yes' or 'No'. For example, if the predicted optimal beam is beam 1 and beam 2, and the measured optimal beam is beam 1, then the predicted optimal beam includes the measured optimal beam, and the beam accuracy indication information can be 'Yes'. As another example, if the predicted optimal beam is beam 1, and the measured optimal beam is beam 1 and beam 2, then the predicted optimal beam is included in the measured optimal beam, and the beam accuracy indication information can be 'Yes'. If the predicted beam is beam 1 and beam 2, and the measured beam is beam 2 and beam 3, then the beam accuracy indication information can be 'No'. If the predicted optimal beam and the measured optimal beam are the same, then the beam accuracy indication information is 'Yes'. For example, if the predicted optimal beam is beam 1, and the measured optimal beam is beam 1, then the beam accuracy indication information is 'Yes'. This disclosure does not provide all examples, but is not limited to these.

[0139] Optionally, when the beam accuracy indication information is "whether the predicted optimal beam includes the measured optimal beam" or "whether the predicted optimal beam is included in the measured optimal beam", if the predicted optimal beam corresponds to at least one of reference signal resources 4, 5, and 6, the prediction result and measurement result are not used to determine the beam accuracy information. This is because the first set of reference signal resources does not include reference signal resources 4, 5, and 6, and the terminal cannot obtain the measurement results for reference signal resources 4, 5, and 6.

[0140] Optionally, when the beam accuracy indication information is "the proportion of times the predicted best beam includes the measured best beam out of the total number of predictions" or "the proportion of times the predicted best beam is included in the measured best beam out of the total number of predictions," some predictions and measurements can be excluded before calculating the proportion. These excluded predictions are the number of times the reference signal resource corresponding to the predicted best beam is not in the first set of reference signal resources. For example, if the measured best beam is beam 1, and assuming three predictions were performed, the predicted best beams are: beam 1 and beam 2, beam 3, and beam 5 and beam 6. It can be understood that in the first two predictions, the reference signal resource corresponding to the predicted best beam is within the first set of reference signal resources and is counted in the total number of predictions. However, in the last prediction, the reference signal resource corresponding to the predicted best beam is not within the first set of reference signal resources, so this prediction is excluded and not counted in the total number of predictions. Therefore, the total number of predictions is 2, and the number of times the predicted best beam includes the measured best beam is 1, the proportion is 1 / 2, that is, the beam accuracy indication information is 1 / 2. The examples in this embodiment are merely illustrative and are not intended to limit the scope of the invention.

[0141] Optionally, when the beam accuracy indication information is "the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the measured optimal beam" and "the difference between the predicted L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the predicted optimal beam", the difference can be calculated if the predicted optimal beam is the beam corresponding to at least one of reference signal resources 1, 2, and 3. For example, if the predicted optimal beam is beam 1 and the measured optimal beam is beam 2, the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2 can be calculated, or the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1 can be calculated. For example, beam accuracy indication information may include 'No' and 'the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2', or 'the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1'. That is, beam accuracy indication information may include more than one of the above. This disclosure is merely an example and is not limited thereto. For example, if the predicted optimal beam is beam 1, and the measured optimal beams are beam 1 and beam 2, the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1 can be calculated. The difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2 can also be calculated. For example, beam accuracy indication information may include at least one of 'Yes', 'the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1', and 'the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2'.

[0142] Optionally, when the beam accuracy indication information is "the proportion of the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the predicted optimal beam within a threshold value" or "the proportion of the difference between the predicted L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the predicted optimal beam within a threshold value", the proportion can be calculated after excluding some times. These excluded times are the times when the reference signal resource corresponding to the predicted optimal beam is not in the first reference signal resource set. For specific implementation methods, please refer to the above embodiments, which will not be repeated here. If only a single instance is considered, i.e., the total number of times is 1, then this proportion can also be directly 'yes' or 'no'.

[0143] Optionally, when the beam accuracy indication information is "the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the best beam" and "the difference between the predicted L1-RSRP corresponding to the best beam and the measured L1-RSRP corresponding to the best beam", if the predicted optimal beam is the beam corresponding to at least one of reference signal resources 4, 5, and 6, the prediction result and measurement result are not used to determine the beam accuracy information. This is because the first set of reference signal resources does not include reference signal resources 4, 5, and 6, and the terminal cannot obtain the measurement results for reference signal resources 4, 5, and 6.

[0144] In some embodiments, if the first reference signal resource set and the third reference signal resource set are the same, the beam accuracy information can be directly determined. Assume that both the first and third reference signal resource sets include reference signal resources 1, 2, and 3.

[0145] Optionally, when the beam accuracy indication information is "whether the predicted optimal beam includes the measured optimal beam" or "whether the predicted optimal beam is included in the measured optimal beam", the beam accuracy information can be directly determined. If the predicted optimal beam and the measured optimal beam are different, the beam accuracy information is 'No'. For example, if the predicted optimal beam is beam 1 and the measured optimal beam is beam 2, the beam accuracy indication information is 'No'. It can be understood that beam 1 here refers to the beam corresponding to reference signal resource 1, and beam 2 refers to the beam corresponding to reference signal resource 2. This disclosure simplifies for ease of description, and the rest are similar. If the predicted optimal beam and the measured optimal beam are partially the same, the beam accuracy information can be 'Yes' or 'No'. For example, if the predicted optimal beam is beam 1 and beam 2, and the measured optimal beam is beam 1, then it is equivalent to the predicted optimal beam including the measured optimal beam, and the beam accuracy indication information can be 'Yes'. For example, if the predicted optimal beam is beam 1, and the measured optimal beams are beams 1 and 2, then the predicted optimal beam is essentially included in the measured optimal beam, and the beam accuracy indication information can be 'Yes'. If the predicted beams are beams 1 and 2, and the measured beams are beams 2 and 3, then the beam accuracy indication information can be 'No'. If the predicted optimal beam and the measured optimal beam are the same, then the beam accuracy indication information is 'Yes'. For example, if the predicted optimal beam is beam 1, and the measured optimal beam is beam 1, then the beam accuracy indication information is 'Yes'. This disclosure does not provide all examples, but is not limited to these.

[0146] Optionally, when the beam accuracy indication information is "the proportion of times the predicted best beam includes the measured best beam out of the total number of predictions" or "the proportion of times the predicted best beam includes the measured best beam out of the total number of predictions," the beam accuracy information can be directly determined. For example, if the measured best beam is beam 1, and assuming three predictions were performed, the predicted best beams are: beam 1, beam 1, and beams 2 and 3, then the total number of predictions is 3, and the number of times the predicted best beam includes the measured best beam is 2, then the beam accuracy indication information is 2 / 3. It is understood that this disclosure does not provide exhaustive examples, but is not limited to these.

[0147] Optionally, when the beam accuracy indication information is "the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the best beam" and "the difference between the predicted L1-RSRP corresponding to the best beam and the measured L1-RSRP corresponding to the best beam", the beam accuracy information can be directly determined. For example, if the predicted optimal beam is 1 and the measured optimal beam is 2, the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2 can be calculated, or the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1 can be calculated. As another example, the beam accuracy indication information may include 'No' and 'the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2', or 'the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1'. That is, the beam accuracy indication information may include more than one of the above; this disclosure is merely an example and not limited thereto. For example, if the predicted optimal beam is beam 1, and the measured optimal beams are beam 1 and beam 2, the difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1 can be calculated. Alternatively, the difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2 can also be calculated. For instance, beam accuracy indication information may include at least one of 'Yes', 'Difference between the predicted L1-RSRP of beam 1 and the measured L1-RSRP of beam 1', and 'Difference between the measured L1-RSRP of beam 1 and the measured L1-RSRP of beam 2'.

[0148] Optionally, when the beam accuracy indication information is 'the proportion of the difference between the measured L1-RSRP corresponding to the predicted optimal beam and the measured L1-RSRP corresponding to the best beam within a threshold value' or 'the proportion of the difference between the predicted L1-RSRP corresponding to the best beam and the predicted L1-RSRP corresponding to the best beam within a threshold value', the beam accuracy information can be directly determined. Specific implementation methods can be found in the above embodiments, and will not be elaborated upon here. If only a single instance is considered, i.e., the total number of times is 1, then this proportion can also be directly 'yes' or 'no'.

[0149] In some embodiments, the predictive model may be an AI function or an AI model or an ML function or an ML model, etc., which are not limited in this disclosure.

[0150] In some embodiments, the second reference signal resource set may be set B, and the third reference signal resource set may be set A. The relationship between set B and set A can be referred to the above embodiments, and will not be repeated here. The first reference signal resource set may be a subset of set A, and a subset of set A includes sets that are the same as set A or proper subsets of set A.

[0151] Understandably, it is necessary to address which combinations of time-domain characteristics are supported by the first and second CSI report configuration information, and how the first and / or second CSI report configuration identifiers are activated or triggered.

[0152] In some embodiments, the network device may indicate the temporal characteristics of the reports corresponding to the first and second CSI report configuration identifiers.

[0153] Optionally, the report corresponding to the first CSI report configuration identifier is a periodic report, and the report corresponding to the second CSI report configuration identifier is also a periodic report. For example, if the report corresponding to the first CSI report configuration identifier is a periodic report, then the report corresponding to the second CSI report configuration identifier is also a periodic report.

[0154] Optionally, the report corresponding to the first CSI report configuration identifier is a semi-permanent report, and the report corresponding to the second CSI report configuration identifier is a periodic report or a semi-permanent report. For example, if the report corresponding to the first CSI report configuration identifier is a semi-permanent report, then the report corresponding to the second CSI report configuration identifier is a periodic report or a semi-permanent report.

[0155] Optionally, the report corresponding to the first CSI report configuration identifier is a non-periodic report, while the report corresponding to the second CSI report configuration identifier is a periodic report, a semi-permanent report, or a non-periodic report. For example, if the report corresponding to the first CSI report configuration identifier is a non-periodic report, then the report corresponding to the second CSI report configuration identifier is a periodic report, a semi-permanent report, or a non-periodic report.

[0156] Optionally, if the report corresponding to the second CSI report configuration identifier is a periodic report, then the report corresponding to the first CSI report configuration identifier can be a periodic report, a semi-permanent report, or a non-periodic report.

[0157] Optionally, if the report corresponding to the second CSI report configuration identifier is a semi-permanent report, then the report corresponding to the first CSI report configuration identifier can be a semi-permanent report or a non-periodic report.

[0158] Optionally, if the report corresponding to the second CSI report configuration identifier is a non-periodic report, then the report corresponding to the first CSI report configuration identifier can also be a non-periodic report.

[0159] In some embodiments, the first information may be carried by Radio Resource Control (RRC) signaling, or the first information may be RRC signaling, without limitation in this disclosure.

[0160] In step S2102, network device 102 sends second information to terminal 101.

[0161] In some embodiments, terminal 101 receives second information sent by network device 102.

[0162] In some embodiments, the second information is used to activate or trigger the first CSI report configuration identifier and / or the second CSI report configuration identifier. For example, when the terminal receives the first information, for semi-permanent or non-periodic reports, the terminal does not immediately begin to determine beam determination information, but after receiving the second information, determines beam accuracy indication information based on the first CSI report configuration identifier and / or the second CSI report configuration identifier activated or triggered by the second information.

[0163] For example, the second information can be used to activate or trigger the first CSI report configuration identifier. The terminal can determine the first CSI report configuration information and the second CSI report configuration information corresponding to the second CSI report configuration identifier associated with the first CSI report configuration identifier based on the first CSI report configuration identifier. The first CSI report configuration information and the second CSI report configuration information are used to determine the beam accuracy indication information. The method for determining the beam accuracy indication information can refer to the embodiment in step S2101 above, which will not be repeated here.

[0164] For example, the second information can be used to activate or trigger the second CSI report configuration identifier. The terminal can determine the second CSI report configuration information based on the second CSI report configuration identifier, and determine the second reference signal resource set and the third reference signal resource set based on the second CSI report configuration information. The measurement results of the second reference signal resources are input into the AI / ML model to obtain the prediction results corresponding to the third reference signal resource set. The second CSI report contains the prediction results corresponding to the third reference signal resource set. The method for determining the prediction results corresponding to the third reference signal resource set can refer to the embodiment in step S2101 above, which will not be repeated here.

[0165] Optionally, determining the third reference signal resource set based on the second CSI report configuration information may involve including the third reference signal resource set in the second CSI report configuration information.

[0166] Optionally, determining the third reference signal resource set based on the second CSI report configuration information may involve the second CSI report configuration information including an associated ID. If the terminal also has the same associated ID in other previously received CSI report configuration information, then the reference signal resource set contained in that other CSI report configuration information can be determined as the third reference signal resource set.

[0167] In some embodiments, the first CSI report configuration identifier and the second CSI report configuration identifier are configured in the same list. For example, the list includes the first CSI report configuration identifier #1, the first CSI report configuration identifier #2, the first CSI report configuration identifier #3, the second CSI report configuration identifier #4, the second CSI report configuration identifier #5, and the second CSI report configuration identifier #6.

[0168] In some embodiments, if the first CSI report configuration identifier and the second CSI report configuration identifier are configured in the same list, the second information may include first indication information, which is used to indicate the first CSI report configuration identifier and / or the second CSI report configuration identifier. For example, the first indication information corresponds to 6 bits, with each bit corresponding to one CSI report configuration identifier. For example, the first indication information could indicate 000010, in which case the second information would activate the first CSI report configuration identifier #2. Or, the first indication information could indicate 010010, in which case the second information would activate the first CSI report configuration identifier #2 and the second CSI report configuration identifier #5. It is understood that since the first CSI report configuration identifier and the second CSI report configuration identifier are configured in the same list, the numbers of each CSI report configuration identifier are different. As long as different numbers are indicated, a specific CSI report configuration identifier can be indicated. Therefore, the second information only needs to include the first indication information to indicate the number.

[0169] In some embodiments, if the first CSI report configuration identifier and the second CSI report configuration identifier are configured in the same list, the second information may include first indication information, which is used to indicate the first CSI report configuration identifier and / or the second CSI report configuration identifier. For example, the first indication information corresponds to 3 bits. For instance, if the first indication information indicates 010, then the second information triggers the first CSI report configuration identifier #2. Or, if the first indication information indicates 101, then the second information triggers the second CSI report configuration identifier #5. It is understood that since the first CSI report configuration identifier and the second CSI report configuration identifier are configured in the same list, the numbers of each CSI report configuration identifier are different. As long as different numbers are indicated, a specific CSI report configuration identifier can be indicated. Therefore, the second information only needs to include the first indication information to indicate the number.

[0170] In some embodiments, the first indication information may include multiple bits.

[0171] Optionally, each bit corresponds to a first CSI report configuration identifier or a second CSI report configuration identifier. For example, if the value of a bit is the first value, it means that the first or second CSI report configuration identifier corresponding to that bit is not activated or triggered. If the value of a bit is the second value, it means that the first or second CSI report configuration identifier corresponding to that bit is activated or triggered. The first value can be 0, and the second value can be 1, but is not limited to these.

[0172] For example, suppose there are six CSI report configuration identifiers configured in the same list: First CSI Report Configuration Identifier #1, First CSI Report Configuration Identifier #2, First CSI Report Configuration Identifier #3, Second CSI Report Configuration Identifier #4, Second CSI Report Configuration Identifier #5, and Second CSI Report Configuration Identifier #6. The first indication information may include six bits, from right to left: the first bit corresponds to First CSI Report Configuration Identifier #1, the second bit to First CSI Report Configuration Identifier #2, the third bit to First CSI Report Configuration Identifier #3, the fourth bit to Second CSI Report Configuration Identifier #4, the fifth bit to Second CSI Report Configuration Identifier #5, and the sixth bit to Second CSI Report Configuration Identifier #6. If the six bits of the second information are 100000, then the identifier corresponding to the sixth bit, i.e., Second CSI Report Configuration Identifier #6, is activated or triggered. If the 6 bits of the second information are 000100, then the identifier corresponding to the 3rd bit is activated or triggered, namely the first CSI report configuration identifier #3. This disclosure will not provide examples of each.

[0173] It is understood that the examples “100000” and “000100” are merely illustrative. In this illustrative example, a value of 0 on the bit indicates that it is not activated or not triggered, and a value of 1 on the bit indicates that it is activated or triggered. However, this disclosure does not limit what value indicates activation or triggering, or what value indicates inactivation or inactivation.

[0174] Optionally, multiple bits correspond to a numerical combination, and each numerical combination corresponds to a first CSI report configuration identifier or a second CSI report configuration identifier. Different values ​​in the numerical combination correspond to different CSI report configuration identifiers.

[0175] For example, suppose the second information includes 3 bits, with each bit containing the values ​​1 and 0. Combinations such as "001", "010", and "011" are examples, and this disclosure will not list them all. Each combination of values ​​corresponds to a first CSI report configuration identifier or a second CSI report configuration identifier. For example, "001" corresponds to first CSI report configuration identifier #1, "010" corresponds to first CSI report configuration identifier #2, and "011" corresponds to first CSI report configuration identifier #3. If the combination of values ​​corresponding to the 3 bits included in the first indication information is "001", then first CSI report configuration identifier #1 is activated or triggered; if the combination of values ​​corresponding to the 3 bits included in the first indication information is "010", then first CSI report configuration identifier #2 is activated or triggered, and this disclosure will not list them all.

[0176] For example, the second information includes X bits, each corresponding to a numerical combination. Since the value of each bit is different, multiple bits correspond to different numerical combinations. Each numerical combination corresponds to a CSI report configuration identifier, and the number of CSI report configuration identifiers is Y. That is, X bits can indicate one of Y CSI report configuration identifiers. Here, the value of X is log2(Y) rounded up. `log` represents the logarithm, and `log2(Y)` is the logarithm of Y to the base 2. For example, when Y is 3, X is 2. When Y is between 5 and 8, X is 3.

[0177] In some embodiments, the first CSI report configuration identifier and the second CSI report configuration identifier are configured in different lists. For example, list 1 contains: first CSI report configuration identifier #1, first CSI report configuration identifier #2, and first CSI report configuration identifier #3. List 2 contains: second CSI report configuration identifier #1, second CSI report configuration identifier #2, and second CSI report configuration identifier #3.

[0178] In some embodiments, if the first CSI report configuration identifier and the second CSI report configuration identifier are configured in different lists, the second information may include first indication information and second indication information. The second indication information is used to indicate the list, and the first indication information is used to indicate the first CSI report configuration identifier and / or the second CSI report configuration identifier in the list. For example, the second indication information may indicate list 1, and the first indication information may indicate #1, then the second information activates or triggers the first CSI report configuration identifier #1. As another example, the second indication information may indicate list 2, and the first indication information may indicate #3, then the second information activates or triggers the second CSI report configuration identifier #3. It is understood that since the first CSI report configuration identifier and the second CSI report configuration identifier are configured in different lists, the first CSI report configuration identifier and the second CSI report configuration identifier may have the same number; therefore, the second information may include both the first indication information and the second indication information.

[0179] In some embodiments, the first indication information may include multiple bits.

[0180] Optionally, each bit corresponds to a first CSI report configuration identifier or a second CSI report configuration identifier. For example, if the value of a bit is the first value, it means that the first or second CSI report configuration identifier corresponding to that bit is not activated or triggered. If the value of a bit is the second value, it means that the first or second CSI report configuration identifier corresponding to that bit is activated or triggered. The first value can be 0, and the second value can be 1, but is not limited to these.

[0181] For example, suppose there are 6 CSI report configuration identifiers configured in different lists: First CSI Report Configuration Identifier #1, First CSI Report Configuration Identifier #2, First CSI Report Configuration Identifier #3, Second CSI Report Configuration Identifier #1, Second CSI Report Configuration Identifier #2, and Second CSI Report Configuration Identifier #3. The first indication information can include 3 bits: the first bit corresponds to either the first or second CSI report configuration identifier #1, the second bit corresponds to either the first or second CSI report configuration identifier #2, and the third bit corresponds to either the first or second CSI report configuration identifier #3. Whether it corresponds to the first or second CSI report configuration identifier can be indicated by the second indication information. For example, if list 1 is a list of first CSI report configuration identifiers and list 2 is a list of second CSI report configuration identifiers, assuming the first indication information includes 3 bits of 100, if the second indication information indicates list 1, then the second information activates or triggers the first CSI report configuration identifier #3. If the second instruction information indicates list 2, then the second information activates or triggers the second CSI report configuration identifier #3.

[0182] It is understood that the example of "100" is merely exemplary. In this exemplary example, a value of 0 on the bit indicates that it is not activated or not triggered, and a value of 1 on the bit indicates that it is activated or triggered. However, this disclosure does not limit what value indicates activation or triggering, or what value indicates inactivation or inactivation.

[0183] Optionally, multiple bits correspond to a numerical combination, and each numerical combination corresponds to a first CSI report configuration identifier or a second CSI report configuration identifier. Different values ​​in the numerical combination correspond to different CSI report configuration identifiers.

[0184] For example, suppose the second information includes a first indication information consisting of two bits. The values ​​of each bit are 1 and 0, with combinations such as "00", "01", and "10" not listed here. Each combination corresponds to either a first CSI report configuration identifier or a second CSI report configuration identifier. For example, "00" corresponds to first or second CSI report configuration identifier #1, "01" corresponds to first or second CSI report configuration identifier #2, and "10" corresponds to first or second CSI report configuration identifier #3. Whether it corresponds to the first or second CSI report configuration identifier can be indicated by the second indication information. For example, if List 1 is a list of first CSI report configuration identifiers and List 2 is a list of second CSI report configuration identifiers. Suppose the value combination corresponding to the two bits in the first indication information is "00". If the second indication information indicates List 1, then the second information activates or triggers the first CSI report configuration identifier #1; if the second indication information indicates List 2, then the second information activates or triggers the second CSI report configuration identifier #1. This disclosure does not provide further examples.

[0185] For example, the first indication information includes X bits, each corresponding to a numerical combination. Since the value of each bit is different, multiple bits will correspond to different numerical combinations. Each numerical combination corresponds to a CSI report configuration identifier, and the number of CSI report configuration identifiers is Y. That is, X bits can indicate one of Y CSI report configuration identifiers. Here, the value of X is log2(Y) rounded up. `log` represents the logarithm, and `log2(Y)` is the logarithm of Y to the base 2. For example, when Y is 3, X is 2. When Y is between 5 and 8, X is 3.

[0186] In some embodiments, in addition to the first and second CSI report configuration identifiers, the network device can also configure a third CSI report configuration identifier to the terminal. This third CSI report configuration identifier corresponds to third CSI report configuration information, which is unrelated to beam accuracy indication information. Alternatively, it can be understood that the third CSI report configuration information is CSI report configuration information unrelated to AI / ML, and can be referred to as traditional CSI report configuration information. That is, the reference signal resources in the reference signal resource set determined based on the third CSI report configuration information are all those that need to be measured, not those that need to be predicted, and the corresponding reporting content does not include beam accuracy indication information.

[0187] In some embodiments, the second information may also activate or trigger a third CSI report configuration identifier in a manner similar to that of the first CSI report configuration identifier and the second CSI report configuration identifier, which will not be described in detail here.

[0188] In some embodiments, the first CSI report configuration identifier, the second CSI report configuration identifier, and the third CSI report configuration identifier can be configured in the same list. In this case, the second information only needs to include the first indication information to indicate the CSI report configuration identifier.

[0189] In some embodiments, the first CSI report configuration identifier, the second CSI report configuration identifier, and the third CSI report configuration identifier can be configured in different lists. It is understood that configuring them in different lists can mean that each of them is configured in three separate lists, or that two of them are configured in the same list, and the third is configured in a separate list. For example, since the first and second CSI report configuration identifiers are both related to beam accuracy indication information (AI / ML), they can be configured in the same list, while the third CSI report configuration identifier is unrelated to beam accuracy indication information (AI / ML) and can be configured in a separate list. However, this disclosure is not limited to this. If the second information needs to include second indication information to indicate which list's CSI report configuration identifier is activated or triggered by the second information, specific implementation details can be found in the above embodiments, and will not be repeated here.

[0190] In some embodiments, the second information may be carried by at least one of the following: a Medium Access Control Element (MAC CE); or Downlink Control Information (DCI).

[0191] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0192] For example, the second information can be carried by a MAC CE. Alternatively, the second information can be a MAC CE. The MAC CE can activate at least one CSI report configuration identifier in the first information.

[0193] For example, the second information can be carried by a DCI. Alternatively, the second information can be a DCI. The DCI can trigger at least one CSI report configuration identifier in the first information.

[0194] For example, the second message can be carried by MAC CE and DCI. MAC CE can activate at least one CSI report configuration identifier in the first message, and DCI can trigger one or more of the CSI report configuration identifiers activated by MAC CE.

[0195] In some embodiments, the name of the second information is not limited; for example, it may be activation information or instruction information.

[0196] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2102. For example, step S2101 may be implemented as a standalone embodiment, but is not limited thereto.

[0197] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0198] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0216] Optionally, the second information is carried by the MAC CE.

[0217] Optionally, the second information is carried by the DCI.

[0218] Figure 4 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:

[0219] In step S4101, network device 102 sends CSI report configuration information to terminal 101.

[0220] In some embodiments, terminal 101 receives CSI report configuration information sent by network device 102.

[0221] In some embodiments, the CSI report configuration information (CSIreportconfig) includes a first CSI report configuration identifier and a second CSI report configuration identifier. The first CSI report configuration identifier corresponds to the first CSI report configuration information, and the second CSI report configuration identifier corresponds to the second CSI report configuration information associated with the first CSI report configuration identifier. The reporting amount indicated by the terminal based on the first CSI report configuration information is a beam accuracy indicator.

[0222] In some embodiments, the second CSI report configuration identifier corresponds to the second CSI report configuration information associated with the first CSI report configuration identifier, including at least one of the following:

[0223] (1) In response to the fact that the report corresponding to the first CSI report configuration identifier is a periodic report, the report corresponding to the second CSI report configuration identifier is a periodic report;

[0224] (2) In response to the first CSI report configuration identifier being a semi-persistent report, the second CSI report configuration identifier being a periodic report or a semi-persistent report;

[0225] (3) In response to the first CSI report configuration identifier being a non-periodic report, the second CSI report configuration identifier being a periodic report, a semi-permanent report, or a non-periodic report.

[0226] In some embodiments, the beam accuracy indication is determined based on reference signal resources in the first CSI report configuration information and reference signal resources in the second CSI report configuration information.

[0227] In some embodiments, the method for determining beam accuracy indication is as follows:

[0228] The terminal determines a first reference signal resource set (set B) and a second reference signal resource set (set A) based on the configuration information of the second CSI report. Based on the measurement results of the first reference signal resource set and the AI / ML function / model, the terminal obtains the beam prediction results corresponding to the second reference signal resource set. The prediction results include the best K beam identifiers (IDentity, ID) and / or the L1-RSRP corresponding to at least one beam. Here, K is a positive integer.

[0229] The terminal determines the third set of reference signal resources (which may be set A or a subset of set A) for performance monitoring based on the configuration information of the first CSI report, and obtains the actual measurement results, which include the best beam ID in set A and / or the L1-RSRP corresponding to at least one beam.

[0230] The terminal obtains the value corresponding to the beam accuracy indication based on the prediction results and measurement results.

[0231] In some embodiments, the CSI report configuration information may be the first information described in the above embodiments.

[0232] In step S4102, network device 102 sends MAC CE and / or DCI to terminal 101.

[0233] In some embodiments, terminal 101 receives MAC CE and / or DCI sent by network device 102.

[0234] In some embodiments, MAC CE and / or DCI are used to activate the first CSI report configuration identifier.

[0235] In some embodiments, if the RRC signaling configures the first CSI report configuration information, for the reporting of semi-persistent or non-periodic CSI reports, further MAC CE or DCI is required to activate or trigger the corresponding CSIreportconfig ID.

[0236] In some embodiments, the MAC CE activation scheme is as follows:

[0237] (1) The first MAC CE includes X bits, each bit corresponding to a CSI report configuration identifier. If the bit is '1' or '0', it means that the CSI report configuration corresponding to the identifier is activated, otherwise it is not activated.

[0238] (2) The first MAC CE includes X bits, and there are a total of Y CSI report configuration identifiers. The X bit indicates one of the Y identifiers, and the value of X is log 2(Y) rounded up. For example, if Y is 3, then X = 2; if Y is 5 to 8, then X = 3. Thus, '000' indicates the first CSI report configuration with activation identifier 0, '001' indicates the first CSI report configuration with activation identifier 1, and so on.

[0239] It's important to note that this refers to the existence of multiple CSI report configuration identifiers. Scenario 1: Multiple CSI report configuration identifiers may all contain the first CSI report configuration identifier; Scenario 2: Multiple CSI report configuration identifiers may all contain the second CSI report configuration identifier; Scenario 3: Multiple CSI report configuration identifiers may contain both the first and second CSI report configuration identifiers; Scenario 4: Multiple CSI report configuration identifiers may contain the first, second, and third CSI report configuration identifiers. The first CSI report configuration identifier corresponds to a type of CSI report configuration identifier used for AI / ML functions or model performance monitoring; the second CSI report configuration identifier corresponds to a type of CSI report configuration identifier used for AI / ML functions or model inference; and the third CSI report configuration identifier corresponds to a traditional CSI report configuration identifier, i.e., a type of CSI report configuration identifier unrelated to AI / ML functions or models. These scenarios 1-4 may correspond to different MAC CE designs.

[0240] In some embodiments, the MAC CE further includes indication information indicating that the MAC CE applies to a first list. This corresponds to cases 1-3, meaning that different types of CSI report configuration identifiers correspond to different lists, and these identifiers are simply numbers within those lists. Activating a CSI report configuration identifier in a different type of list requires sending a different MAC CE to indicate this.

[0241] Example 1 is as follows:

[0242] List 1 contains: First CSI report configuration identifier #1, First CSI report configuration identifier #2, and First CSI report configuration identifier #3.

[0243] List 2 contains: Second CSI report configuration identifier #1, Second CSI report configuration identifier #2, and Second CSI report configuration identifier #3.

[0244] When the MAC CE includes 2 bits to indicate the report configuration identifier, 2 bits being '01' indicates that the report configuration identifier is #2. However, since there are two lists, the terminal does not know whether it is referring to list 1 or list 2. Therefore, the MAC CE also needs to indicate whether list 1 or list 2 applies to the MAC CE.

[0245] Example 2 is as follows:

[0246] List 1 contains: First CSI report configuration identifier #1, First CSI report configuration identifier #2, First CSI report configuration identifier #3, Second CSI report configuration identifier #4, Second CSI report configuration identifier #5, and Second CSI report configuration identifier #6.

[0247] When the MAC CE contains 3 bits to indicate the report configuration identifier, 3 bits being '01' indicates that the report configuration identifier is #2. In this case, there is only one list, so the MAC CE does not need to indicate which list the MAC CE applies to, and the terminal can directly know that the first CSI report configuration identifier #2 is activated.

[0248] As shown above, since three types of CSI report configuration identifiers are given, it is possible that the three types form a single list, in which case the list indication information in MAC CE is not needed; it is also possible that the three types form two lists, with the first and second CSI report configuration identifiers both related to AI / ML forming one list, while the traditional ones unrelated to AI / ML form another list, in which case MAC CE needs to indicate which of the two lists it is; it is also possible that the three types form three separate lists, in which case MAC CE needs to indicate which of the three lists it is.

[0249] In some embodiments, the above embodiments all use MAC CE as an example. If DCI is received, the X bit in DCI also needs to indicate which CSI report configuration identifier was triggered. Furthermore, DCI also needs list indication information. The difference between MAC CE and DCI is that MAC CE indicates the CSI report configuration identifiers included in the RRC configuration list, while DCI can indicate the CSI report configuration identifiers included in the RRC configuration list. Alternatively, if the RRC configuration list contains too many CSI report configuration identifiers (e.g., 16), and a MAC CE activates a portion of the CSI report configuration identifiers in the RRC configuration list (e.g., 8), DCI only indicates one or more of the CSI report configuration identifiers activated by MAC CE (i.e., DCI only needs 3 bits to indicate one of the 8; otherwise, it needs 4 bits to indicate one of the 16).

[0250] It is understood that the methods disclosed herein include RRC+MAC CE, RRC+DCI, or RRC+MAC CE+DCI.

[0251] The communication method involved in the embodiments of this disclosure may include at least one of steps S4101 to S4102. For example, step S4101 may be implemented as a standalone embodiment, but is not limited thereto.

[0252] In some embodiments, step S4102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
