[0040] To enable those skilled in the art to better understand the embodiments of this application, the following description will be provided first.

[0041] I. Background Introduction to AI / ML-BM

[0042] 1) During the model training phase based on AI / ML beam management, the terminal needs to perform channel measurements on the NZP-CSI-RS resources corresponding to the beams in beam set Set A and beam set Set B to obtain measurement results. The beam measurement results in Set B serve as the input to the model and may be the L1-RSRP of the beams in Set B; while the beam measurement results in Set A serve as the data source for obtaining model labels and may be the L1-RSRP of the beams in Set A or the RS ID corresponding to the Top-K beams.

[0043] 2) In the model inference stage based on AI / ML beam management, the terminal needs to perform channel measurement on the NZP-CSI-RS resources corresponding to the beams in Set B to obtain the measurement results. The beam measurement results in Set B are used as the input of the model. Then, based on the AI / ML model, the RS id corresponding to the Top-K beams in Set A or the RSRP of the beams in Set A is inferred.

[0044] II. CSI Framework Configuration Introduction

[0045] 1) CSI Resource Configuration: Each CSI resource configuration includes the configuration of a CSI resource set table, which consists of a set of reference signals. For periodic or semi-persistent CSI-RS signals, when reporting L1-RSRP, if multi-TRP is supported, a maximum of two resource sets can be configured in each CSI resource configuration; otherwise, only one resource set can be configured in each CSI resource configuration. When reporting other quantities (such as L1-SINR), the configured resource sets include those used for measuring interference, i.e., the number of sets can be greater than one.

[0046] 2) CSI reporting configuration: Each CSI reporting configuration can be associated with a resource configuration for signal measurement. For resource configurations used for channel measurement, the reporting quality 'reportQuantity' mainly includes the L1-RSPR corresponding to CRI or SSBRI.

[0047] III. UE-sided model

[0048] Table 1 below shows the correspondence between terminal-side model measurement configuration and reporting configuration. In AI beam management, during the training phase of the terminal-side model, when the terminal is configured with multiple resource sets for AI beam management or non-AI beam management purposes, the terminal needs to know the relationship between the resource sets corresponding to Set A and Set B. However, the current protocol does not have a method for determining the association between Set A and Set B. A method is needed to determine the association between Set A and Set B so that the terminal knows that the measurement results of Set A and Set B are used for the training of a model. At the same time, during the inference phase of the terminal-side model, which is equivalent to the UE measuring Set B and reporting Set A, the UE also needs to know the association between Set A and Set B.

[0049] Table 1. Correspondence between Measurement Configuration and Reporting Configuration

[0050]

[0051]

[0052] IV. Network-side model (NW-sided model)

[0053] Table 2 below shows the correspondence between network-side model measurement configuration and reporting configuration. In AI beam management, during the training phase of the network-side model, when a terminal is configured with multiple resource sets for AI beam management or non-AI beam management purposes, the terminal can simultaneously report the measurement results of Set A and Set B beams measured at the same or similar times. However, the current CSI framework does not support the simultaneous reporting of Set A and Set B measurement results.

[0054] Table 2. Correspondence between Measurement Configuration and Reporting Configuration

[0055] Network-side model Measurement configuration Report configuration train Measurement set A and measurement set B Report the measurement results of Set B and the labels in Set A. reasoning Measurement Set B Report beam information related to Set B

[0056] As discussed above, in AI beam management, whether it's a terminal-side model or a network-side model, when a terminal is configured with multiple resource sets for AI beam management or non-AI beam management purposes, the terminal needs to know the relationship between the resource sets corresponding to Set A and Set B. This allows the terminal to know how to use the measurement results of Set A and Set B for the training or inference of a model. However, there is currently no solution for determining the correlation between the reference signal resource set corresponding to Set A and the reference signal resource set corresponding to Set B.

[0057] Based on the above, embodiments of this application provide a method, indication method, apparatus, terminal, and network device for determining association relationships, in order to solve the problem that in beam management, the terminal cannot determine the association relationship between the reference signal resource set corresponding to Set A and the reference signal resource set corresponding to Set B.

[0058] The method for determining the association relationship provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0059] See Figure 2 This application provides a method for determining association relationships, applied to a terminal, including the following steps:

[0060] Step 201: Receive first configuration information sent by the network device, the first configuration information being used to indicate the association between the first reference signal resource set and the second reference signal resource set; wherein, the first configuration information is channel state information (CSI) resource configuration information or CSI report configuration information.

[0061] In the AI / ML model training process, the first beam set setA corresponds to the first reference signal resource set, the second beam set setB corresponds to the second reference signal resource set, the measurement results of the first reference signal resource set are used as label information, and the measurement results corresponding to the second reference signal resource set are used as the input data of the model.

[0062] Step 202: Determine the association between the first reference signal resource set and the second reference signal resource set based on the first configuration information.

[0063] If there is a correlation between the first reference signal resource set and the second reference signal resource set, it can be determined that the measurement results of the first reference signal resource set and the second reference signal resource set are used for the training or inference of the same model.

[0064] In the above embodiments, the terminal can receive first configuration information sent by the network device and determine, according to the instructions of the first configuration information, that there is an association between the first reference signal resource set and the second reference signal resource set, so that the terminal can determine that the measurement results of the first reference signal resource set and the second reference signal resource set are used for the training or inference of the same model when performing beam management.

[0065] The following describes the methods for determining association relationships, mainly including the following two schemes:

[0066] Option 1: The first configuration information is the CSI resource configuration information.

[0067] In some alternative embodiments, when the first configuration information is CSI resource configuration information, the CSI resource configuration information indicates the association between the first reference signal resource set and the second reference signal resource set in the following manner:

[0068] Method 1: The CSI resource configuration information is associated with the first reference signal resource set and the second reference signal resource set;

[0069] It should be noted that the first reference signal resource set or the second reference signal resource set may consist of one or more CSI-RS sets. For example, the first reference signal resource set is used to configure the first beam set Set A. Assuming Set A includes 256 beams, one approach is to extend the number of CSI-RS included in the existing CSI resource set to N (e.g., N = 256), then Set A = {CSI-RS 0, CSI-RS 1, ..., CSI-RS 255}; another approach is to have Set A composed of M = 4 CSI-RS sets, then Set 0 = {CSI-RS 0, CSI-RS 1, ..., CSI-RS 63}, Set 1 = {CSI-RS 0, CSI-RS 1, ..., CSI-RS 63}, Set 2 = {CSI-RS 0, CSI-RS 1, ..., CSI-RS 63}, Set 3 = {CSI-RS 0, CSI-RS 1, ..., CSI-RS 63}.

[0070] In Method 1 above, the network device indicates that the first reference signal resource set and the second reference signal resource set are associated by configuring them in the same CSI resource configuration. Correspondingly, the terminal determines that the first reference signal resource set and the second reference signal resource set are associated through the CSI resource configuration information, and determines that the first reference signal resource set and the second reference signal resource set are CSI-RS resources that enable the same AI / ML model or AI / ML function through the association relationship. Among them, the first reference signal resource set is the CSI-RS resource explicitly configured for the first beam set setA, and the second reference signal resource set is the CSI-RS resource explicitly configured for the second beam set setB.

[0071] Optionally, the CSI resource configuration information (CSI-ResourceConfig) in the high-level RRC parameters can be used as the first configuration information.

[0072] Example 1:

[0073] The network device configures the first reference signal resource set corresponding to Set A in the nzp-CSI-RS-ResourceSetListforAI-r19 field of CSI-ResourceConfig; and configures the second reference signal resource set corresponding to Set B in the csi-SSB-ResourceSetListExtforAI-r19 field of CSI-ResourceConfig; wherein, NZP-CSI-RS-ResourceSetIdforAI-r19 = Set A id, and Set A id is associated with one or more CSI-RS set IDs; NZP-CSI-RS-ResourceSetIdforAI-r19 = Set B id, and Set B id is associated with one or more CSI-RS set IDs.

[0074] It should be noted that using the nzp-CSI-RS-ResourceSetListforAI-r19 field to configure the first reference signal resource set corresponding to Set A, and using the csi-SSB-ResourceSetListExtforAI-r19 field to configure the second reference signal resource set corresponding to Set B, is only an example. Other fields can also be used, and this is not a limitation.

[0075] Accordingly, the terminal, based on the received first configuration information, learns the association between the first reference signal resource set and the second reference signal resource set, and determines that the CSI-RS resources in the first reference signal resource set are the prediction CSI-RS resource set for the AI / ML model, i.e., the CSI-RS resource set corresponding to Set A, and the CSI-RS resources in the second reference signal resource set are the CSI-RS resource set required for the input of the AI / ML model, i.e., the CSI-RS resource set corresponding to Set B. Simultaneously, the terminal device, based on the identifier representing the reference signal resource set in the received first configuration information, such as a CSI-RS set id, or the configuration representing the composition of the reference signal resource set, such as a CSI-RS set list, determines the composition of the CSI-RS resources in the first or second reference signal resource set.

[0076] Example 2,

[0077] The network device configures the first reference signal resource set corresponding to Set A in the nzp-CSI-RS-ResourceSetListforAI-r19 field of CSI-ResourceConfig; and configures the second reference signal resource set in the csi-SSB-ResourceSetListExtforAI-r19 field of CSI-ResourceConfig; wherein, multiple Set sets in NZP-CSI-RS-ResourceSetIdforAI-r19 are combined to form Set A, and the list includes Set0, Set1, Set2, and Set3, which together constitute Set A; NZP-CSI-RS-ResourceSetIdforAI-r19 = Set B id, and Set B id is associated with one or more CSI-RS set IDs.

[0078] It should be noted that using the nzp-CSI-RS-ResourceSetListforAI-r19 field to configure the first reference signal resource set corresponding to Set A, and using the csi-SSB-ResourceSetListExtforAI-r19 field to configure the second reference signal resource set corresponding to Set B, is only an example. Other fields can also be used, and this is not a limitation.

[0079] Accordingly, the terminal, based on the received first configuration information, learns the association between the first reference signal resource set and the second reference signal resource set, and determines that the CSI-RS resources in the first reference signal resource set are the prediction CSI-RS resource set for the AI / ML model, i.e., the CSI-RS resource set corresponding to Set A, and the CSI-RS resources in the second reference signal resource set are the CSI-RS resource set required for the input of the AI / ML model, i.e., the CSI-RS resource set corresponding to Set B. Simultaneously, the terminal device, based on the identifier representing the reference signal resource set in the received first configuration information, such as a CSI-RS set id, or the configuration representing the composition of the reference signal resource set, such as a CSI-RS set list, determines the composition of the CSI-RS resources in the first or second reference signal resource set.

[0080] Method 2: The CSI resource configuration information is associated with the first reference signal resource set, and the first reference signal resource set indicates its association with the second reference signal resource set through first implicit information;

[0081] It should be noted that the second set of reference signal resources in this method 2 is a subset of the first set of reference signal resources.

[0082] In this method 2, the terminal device obtains the first reference signal resource set corresponding to the first beam set Set A through CSI resource configuration information, and then determines the second reference signal resource set corresponding to the second beam set Set B according to the first implicit indication information. In other words, the CSI-RS resources corresponding to Set B are implicitly configured.

[0083] Optionally, the first implicit indication information includes one of the following two methods:

[0084] Method 21: At least one bitmap corresponding to the first reference signal resource set, wherein the at least one bitmap indicates the reference signal resource distribution of the second reference signal resource set.

[0085] Optionally, at least one bitmap corresponding to the first reference signal resource set includes: a first bitmap and / or at least one second bitmap corresponding to the first reference signal resource set; wherein, the first reference signal resource set is composed of multiple reference signal resource sets, the first bitmap is used to indicate whether each of the reference signal resource sets belongs to a candidate resource set of the second reference signal resource set; the second bitmap is used to indicate the distribution of reference signal resources belonging to the second reference signal resource set in each of the reference signal resource sets.

[0086] Optionally, the length of the second bitmap is the same as the maximum number of CSI-RS resources included in each RS set in the first reference signal resource set. For example, if the first reference signal resource set includes 3 resource sets and the number of CSI-RS resources in the 3 resource sets are 30, 30 and 40 respectively, then the length of the second bitmap is 40 bits.

[0087] Optionally, the length of the first bitmap is the same as the number of RS resource sets included in the first reference signal resource set.

[0088] For example, the method for a terminal to determine the association relationship between a first reference signal resource set and a second reference signal resource set includes the following steps:

[0089] Step 1: The network device sends first configuration information, such as CSI-ResourceConfig, to the terminal, including the first reference signal resource set (first CSI-RS resource set) of Set A and first implicit indication information. The first reference signal resource set corresponding to Set A consists of four RS sets, totaling 256 CSI-RS resources: RS set 1 = {RS0, RS1, RS2…RS63}, RS set 2 = {RS0, RS1, RS2…RS63}, and RS set 3 = {RS0, RS1, RS2…RS63}. The second reference signal resource set (second CSI-RS resource) corresponding to Set B is a subset of the first reference signal resource set (first CSI-RS resource set), and includes 64 CSI-RS resources.

[0090] As one implementation, implicitly indicating the second reference signal resource set through the first implicit indication information includes: indicating CSI-RS resources in the first reference signal resource set that are also in the second reference signal resource set through a second bit map of length 64 bits; and indicating which reference signal resource set included in the first reference signal resource set can be used as a candidate resource set for the second reference signal resource set through a first bit map of length 4 bits.

[0091] For example, if the second bitmap = {1, 0, 0, 0, 1, ..., 0}, then it indicates that the first CSI-RS and the fourth CSI-RS in each RS set included in the first reference signal resource set belong to Set B, and so on.

[0092] For example, if the first bitmap = {1, 1, 0, 0}, then the first RSset and the second RSset included in the first reference signal resource set are candidate resource sets corresponding to Set B.

[0093] It should be noted that by using the first scheme to indicate the second reference signal resource set, compared with introducing a 256-bit bitmap for indication, the indication signaling can be saved by 64*3-4=188 bits.

[0094] Step 2: The terminal device receives the first configuration information, determines the CSI-RS resource in the first reference signal resource set corresponding to Set A, and determines the CSI-RS resource in the second reference signal resource set corresponding to Set B according to the first implicit indication information.

[0095] Specifically, the terminal determines that the resource set of Set A is the CSI-RS resource set consisting of RS set1, RS set2, RS set3 and RS set4.

[0096] Specifically, the terminal determines the resource set of Set B by: the terminal determines the candidate RS set as RS set1 and RS set2 according to the first bit map = {1, 1, 0, 0}; then, according to the second bit map, the CSI-RS resources in RS set1 and RS set2 that belong to the second reference signal resource set are determined respectively.

[0097] Method 22: The distribution interval and starting offset of the reference signal resources in the second reference signal resource set in the first reference signal resource set.

[0098] For example, the method for a terminal to determine the association relationship between a first reference signal resource set and a second reference signal resource set includes the following steps:

[0099] Step 1: The network device sends first configuration information, such as CSI-ResourceConfig, to the terminal, including the first reference signal resource set (first CSI-RS resource set) of Set A and first implicit indication information. The first reference signal resource set corresponding to Set A consists of four RS sets, totaling 256 CSI-RS resources: RS set 1 = {RS0, RS1, RS2…RS63}, RS set 2 = {RS0, RS1, RS2…RS63}, and RS set 3 = {RS0, RS1, RS2…RS63}. The second reference signal resource set (second CSI-RS resource) corresponding to Set B is a subset of the first reference signal resource set (first CSI-RS resource set), and includes 64 CSI-RS resources.

[0100] As one implementation, implicitly indicating the second reference signal resource set through the first implicit indication information includes: indicating the distribution density N and starting offset of the CSI-RS resources corresponding to Set B in the first reference signal resource set through the first parameter (e.g., nAndSetBRSoffset).

[0101] For example, the selectable density N of nAndSetBRSoffset is 1, 2, 4, 8, or 16, and the selectable range of offset is [0, ..., N-1]. A specific illustration is shown below:

[0102]

[0103] It should be noted that, compared with the first scheme, the second scheme can save more instruction signaling overhead, but the CSI-RS resources corresponding to setB need to be evenly distributed in the first reference signal resource set.

[0104] Step 2: The terminal device receives the first configuration information, determines the CSI-RS resource in the first reference signal resource set corresponding to Set A, and determines the CSI-RS resource in the second reference signal resource set corresponding to Set B according to the first implicit indication information.

[0105] Specifically, the terminal determines that the resource set of Set A is the CSI-RS resource set consisting of RS set1, RS set2, RS set3 and RS set4.

[0106] Specifically, the terminal determines the resource set of Set B by: determining the distribution interval and starting offset of the CSI-RS resources corresponding to Set B in the first reference signal resource set based on the first parameter. For example, if there are 16 RSs in the first resource set, and the RS labels in the set are represented as [RS0, RS1, RS2, RS3, RS4, RS4, ..., RS15], and the distribution interval is configured as N = 4 with a corresponding offset of n = 0, then the second resource set is indicated as [RS0, RS4, RS8, RS12]. If N = 4 with a corresponding offset of n = 3, then the second resource set is indicated as [RS3, RS7, RS10, RS15].

[0107] Method 3: The CSI resource configuration information is associated with the second reference signal resource set, and the second reference signal resource set indicates its association with the first reference signal resource set through second implicit information.

[0108] It should be noted that this method 3 is applicable to scenarios where the first reference signal resource set and the second reference signal resource set are different.

[0109] In this method 3, the terminal device obtains the second reference signal resource set corresponding to the second beam set Set B through the CSI resource configuration information, and then determines the first reference signal resource set corresponding to the first beam set Set A according to the second implicit indication information. In other words, the CSI-RS resources corresponding to Set A are implicitly configured.

[0110] Optionally, the second implicit indication information includes: quasi-co-location QCL extension information, used to indicate the quasi-co-location extension relationship between the first reference signal resource set and the second reference signal resource set.

[0111] For example, the method for a terminal to determine the association relationship between a first reference signal resource set and a second reference signal resource set includes the following steps:

[0112] Step 1: The network device sends the first configuration information to the terminal, such as CSI-ResourceConfig, which includes the CSI-RS resource set information of SetB and the second implicit indication information.

[0113] Assume Set B is a wide beam, such as an SSB beam, and Set A is a narrow beam. Set A and Set B have a QCL relationship. The second reference signal resource set corresponding to Set B includes four SSB beams, distributed as Set B = {SSB0, SSB1, SSB2, SSB3}.

[0114] If the CSI-RS resources of Set A are determined based on the enhanced QCL relationship of Set B, then the second implicit indication information indicates the quasi-co-address QCL extension information L=4.

[0115] In this way, the terminal can obtain RS0, RS1, RS2 and RS3 in the first reference signal resource set based on SSB0, that is, the QCL source of RS0, RS1, RS2 and RS3 in SetA is SSB0 in the second reference signal resource set; similarly, four RS resources can be obtained based on SSB1, SSB2 and SSB3 respectively.

[0116] Step 2: The terminal device receives the first configuration information and determines the CSI-RS resource in the second reference signal resource set corresponding to Set B; according to the second implicit indication information, it determines the CSI-RS resource in the first reference signal resource set.

[0117] Specifically, the terminal determines the second set of reference signal resources corresponding to Set B: {SSB0, SSB1, SSB2, SSB3}.

[0118] Specifically, the terminal determines the number of CSI-RS resources included in the first reference signal resource set based on the product of the number in Set B and L according to the resource set of Set A. For example, based on the 4 SSBs and QCL extension relationship in Set B, the terminal can determine the number of CSI-RS resources included in the first reference signal resource set.

[0119] Option 2: The first configuration information is the CSI report configuration information.

[0120] In some optional embodiments, when the first configuration information is CSI report configuration information, the CSI report configuration information indicates the association between the first reference signal resource set and the second reference signal resource set in the following manner:

[0121] Method A: The CSI report configuration information is associated with a first CSI resource configuration and a second CSI resource configuration. The first CSI resource configuration is used to configure the first reference signal resource set, and the second CSI resource configuration is used to configure the second reference signal resource set.

[0122] For example, a CSI report configuration information CSI-ReportConfig is associated with the second CSI resource configuration of Set B and the first CSI resource configuration of Set A; wherein, CSI-ResourceConfigId = first CSI resource configuration for Set B, and the parameter CSI-ResourceConfigId = second CSI resource configuration for Set B is introduced.

[0123] The pseudocode is as follows:

[0124]

[0125] In Method A above, the network device indicates that there is an association between the first reference signal resource set and the second reference signal resource set by associating the first CSI resource configuration and the second CSI resource configuration with a CSI report configuration information. Correspondingly, the terminal determines that there is an association between the first reference signal resource set and the second reference signal resource set through the CSI report configuration information, and determines that the first reference signal resource set and the second reference signal resource set are CSI-RS resources that enable the same AI / ML model or AI / ML function through the association relationship. Among them, the first reference signal resource set is the CSI-RS resource explicitly configured for the first beam set setA, and the second reference signal resource set is the CSI-RS resource explicitly configured for the second beam set setB.

[0126] Method B: The CSI report configuration information is associated with the first CSI resource configuration and the second reference signal resource set. The first CSI resource configuration is used to configure the first reference signal resource set, and the first reference signal resource set indicates its association with the second reference signal resource set through first implicit information.

[0127] It should be noted that the second set of reference signal resources in this method B is a subset of the first set of reference signal resources.

[0128] Optionally, the first implicit indication information includes:

[0129] At least one bitmap corresponding to the first reference signal resource set, wherein the at least one bitmap indicates the distribution of reference signal resources of the second reference signal resource set; or

[0130] The distribution interval and starting offset of the reference signal resources in the second reference signal resource set in the first reference signal resource set.

[0131] Optionally, at least one bitmap corresponding to the first reference signal resource set includes: a first bitmap and / or at least one second bitmap corresponding to the first reference signal resource set; wherein, the first reference signal resource set is composed of multiple reference signal resource sets, the first bitmap is used to indicate whether each of the reference signal resource sets belongs to a candidate resource set of the second reference signal resource set; the second bitmap is used to indicate the distribution of reference signal resources belonging to the second reference signal resource set in each of the reference signal resource sets.

[0132] For example, assume that the first reference signal resource set corresponding to Set A consists of 4 RS sets, totaling 256 CSI-RS resources, namely RS set 1 = {RS0, RS1, RS2…RS63}, RS set 2 = {RS0, RS1, RS2…RS63}, and RS set 3 = {RS0, RS1, RS2…RS63}; the second reference signal resource set (second CSI-RS resource) corresponding to Set B is a subset of the first reference signal resource set (first CSI-RS resource set), and the second reference signal resource set includes 64 CSI-RS resources.

[0133] As one implementation method, implicitly indicating the second reference signal resource set through the first implicit indication information includes the following two methods:

[0134] Method 1: A first bitmap of length 64 bits indicates CSI-RS resources in the first reference signal resource set that also belong to the second reference signal resource set; a second bitmap of length 4 bits indicates which reference signal resource set included in the first reference signal resource set can be used as a candidate resource set for the second reference signal resource set.

[0135] For example, if the second bitmap = {1, 0, 0, 0, 1, ..., 0}, then it indicates that the first CSI-RS and the fourth CSI-RS in each RS set included in the first reference signal resource set belong to Set B, and so on.

[0136] For example, if the first bitmap = {1, 1, 0, 0}, then the first RSset and the second RSset included in the first reference signal resource set are candidate resource sets corresponding to Set B.

[0137] It should be noted that by using the first scheme to indicate the second reference signal resource set, compared with introducing a 256-bit bitmap for indication, the indication signaling can be saved by 64*3-4=188 bits.

[0138] The second method: The distribution density N and the starting offset of the CSI-RS resources corresponding to Set B in the first reference signal resource set are indicated by the first parameter (e.g., nAndSetBRSoffset).

[0139] For example, the optional density of nAndSetBRSoffset is N = 1, 2, 4, 8 or 16, and the optional range of offset is [0, ..., N-1].

[0140] The pseudocode implementation is shown below:

[0141]

[0142] It should be noted that, compared with the first scheme, the second scheme can save more instruction signaling overhead, but the CSI-RS resources corresponding to setB need to be evenly distributed in the first reference signal resource set.

[0143] Method C: The CSI report configuration information is associated with the first reference signal resource set and the second CSI resource configuration. The second CSI resource configuration is used to configure the second reference signal resource set. The second reference signal resource set indicates its association with the first reference signal resource set through second implicit information.

[0144] Optionally, the second implicit indication information includes: quasi-co-location QCL extension information, used to indicate the quasi-co-location extension relationship between the first reference signal resource set and the second reference signal resource set.

[0145] It should be noted that this method C is applicable to scenarios where the first reference signal resource set and the second reference signal resource set are different.

[0146] For example, suppose Set B is a wide beam, such as an SSB beam, and Set A is a narrow beam, with a QCL relationship between Set A and Set B. The second reference signal resource set corresponding to Set B includes four SSB beams, distributed as Set B = {SSB0, SSB1, SSB2, SSB3}. Then, the second implicit indication information indicates a QCL relationship L = 4. Thus, the terminal can obtain RS0, RS1, RS2, and RS3 in the first reference signal resource set based on SSB0. That is, the QCL source of RS0, RS1, RS2, and RS3 in Set A is SSB0 in the second reference signal resource set. Similarly, based on SSB1, SSB2, and SSB3, four RS resources can be obtained respectively. In other words, the terminal can determine the 16 CSI-RS resources included in the first reference signal resource set based on the four SSBs in Set B and the QCL extension relationship.

[0147] For example, a CSI report configuration CSI-ReportConfig associates the CSI resource configuration of Set B with the CSI-RS resources of Set A. Here, CSI-ResourceConfigId = First CSI resource configuration for Set B, and the parameter CSI-RSresource of Set A = Extended QCL relationship, is introduced to indicate the first set of reference signal resources corresponding to the associated Set A.

[0148] The pseudocode is as follows:

[0149]

[0150] Method D: The CSI report configuration information carries the identifier ID of the first reference signal resource set and is associated with the second CSI resource configuration, which is used to configure the second reference signal resource set.

[0151] For example, a CSI report configuration CSI-ReportConfig associates the CSI resource configuration of Set B with the CSI-RS resources of Set A. Here, CSI-ResourceConfigId = the first CSI resource configuration for Set B, and the parameter CSI-RSresource of Set A = ID of set A is introduced to indicate the first reference signal resource set corresponding to the associated Set A.

[0152] The implementation code is as follows:

[0153]

[0154] In this method D, the association between the first reference signal resource set and the second reference signal resource set is indicated by carrying the identifier ID of the first reference signal resource set in the CSI report configuration information and associating the second CSI resource configuration through the CSI report configuration information.

[0155] As an optional embodiment, if the first reference signal resource set or the second reference signal resource set includes multiple reference signal resource sets, and the first condition is met, it is determined that there is an association relationship between the multiple reference signal resource sets.

[0156] The first condition includes at least one of the following:

[0157] The multiple sets of reference signal resources are configured in a single CSI resource configuration information;

[0158] The multiple sets of reference signal resources are configured in a resource list;

[0159] The multiple sets of reference signal resources are configured with the same identifier.

[0160] That is, if the terminal determines that multiple reference signal resource sets in the CSI resource configuration are related by the first condition, it can determine that the multiple reference signal resource sets are used to constitute the first reference signal resource set or the second reference signal resource set.

[0161] For ease of understanding, the association relationship between the first reference signal resource set and the second reference signal resource set can be regarded as the first association relationship, and the association relationship between multiple reference signal resource sets forming the first reference signal resource set or the second reference signal resource set can be regarded as the second association relationship.

[0162] It should be noted that if the same CSI resource configuration information is associated with both the first reference signal resource set and the second reference signal resource set, then the first reference signal resource set and the second reference signal resource set are distinguished by different fields in the CSI resource configuration information.

[0163] In some alternative embodiments, the first configuration information further includes measurement indication information, which is used to indicate whether to perform beam measurement on the first reference signal resource set and / or the second reference signal resource set.

[0164] For example, the network device associates a CSI resource configuration information in the CSI report configuration information. This CSI resource configuration information is associated with a first reference signal resource set corresponding to a first beam set Set A and a second reference signal resource set corresponding to a second beam set Set B. The CSI report configuration information also includes measurement indication information, used to indicate whether to perform beam measurement on the first reference signal resource set and / or the second reference signal resource set; accordingly, the terminal determines the content to be reported based on the measurement indication information.

[0165] For example, the network device associates a first reference signal resource set corresponding to a first beam set Set A and a second reference signal resource set corresponding to a second beam set Set B in the CSI resource configuration information. The CSI resource configuration information also includes measurement indication information to indicate whether beam measurement should be performed on the first reference signal resource set and / or the second reference signal resource set; accordingly, the terminal determines the content to be reported based on the measurement indication information.

[0166] As another optional embodiment, the measurement indication information is used to indicate at least one of the following:

[0167] The first set of reference signal resources is a virtual resource;

[0168] Predict the first set of reference signal resources.

[0169] Optionally, the network device associates the first CSI resource configuration information in the CSI report configuration information. If the first CSI resource configuration information indicates that the first reference signal resource set is a virtual CSI-RS resource or predicts the first reference signal resource set, the terminal reports the measurement results based on the second reference signal resource set, performs AI / ML inference prediction results, and obtains the prediction results of the first reference signal resource set.

[0170] Optionally, if the measurement indication information is used to indicate that the first reference signal resource set is a non-virtual CSI-RS resource, the terminal reports the measurement results of the first reference signal resource set and the second reference signal resource set to the network device.

[0171] It should be noted that the measurement indication information used to indicate the prediction of the first reference signal resource set can be equivalent to the measurement indication information used to indicate no measurement, or the measurement indication information used to indicate that the first reference signal resource set is a virtual resource. That is, the terminal infers the first reference signal resource set based on the measurement results of the second reference signal resource set.

[0172] As an optional embodiment, the measurement indication information is used to indicate at least one of the following:

[0173] a. Measure the first reference signal resource set and the second reference signal resource set;

[0174] b. Measure the first reference signal resource set;

[0175] c. Measure the second reference signal resource set;

[0176] d. Measure the second reference signal resource set, and predict the first reference signal resource set based on the second reference signal resource set.

[0177] For example, assuming that the network device associates the first CSI resource configuration information in the CSI report configuration information it sends, and the CSI resource configuration includes measurement indication information, the terminal can determine the reporting content according to the implicit indication of the measurement indication information; wherein the reporting content includes: the measurement results of the first reference signal resource set and / or the second reference signal resource set, or the prediction results inferred from the first resource set based on AI / ML functions.

[0178] Understandably, if the measurement indication information is a, the terminal needs to measure the CSI-RS resources of Set A and Set B; if the measurement indication information is b, the terminal needs to measure the CSI-RS resources of Set A; if the measurement indication information is c, the terminal needs to measure the CRI-RS resources of Set B; if the measurement indication information is d, the terminal needs to predict the CRI-RS resources corresponding to Set A, that is, the terminal needs to measure the CSI-RS resources of Set B, and use the measurement results as input for the AI / ML function to predict the beam pattern of Set A.

[0179] For example, by using the measurement indication information to correspond to a 2-bit indication field, when the first bit of the measurement indication information corresponds to indication a and the second bit of the measurement indication information corresponds to indication d, the actual measurement result of the first reference signal resource set and the prediction result of the first reference signal resource set are reported; when the first bit of the measurement indication information corresponds to indication b and the second bit of the measurement indication information corresponds to indication d, the actual measurement result of the second reference signal resource set and the prediction result of the first reference signal resource set are reported.

[0180] It should be noted that, when the measurement indication information is used to indicate the measurement of the first reference signal resource set and / or the measurement of the second reference signal resource set, the network device may also send CSI report configuration information to the terminal to indicate the reporting content corresponding to the first reference signal resource set and / or the second reference signal resource set. The reporting content includes prediction results or measurement results.

[0181] For example, if the measurement indication information is used to indicate the measurement of the second reference signal resource set, and the CSI report configuration information is used to indicate the reporting of the prediction result, then the terminal obtains the measurement result of the second reference signal resource set, and based on the measurement result of the second reference signal resource set, obtains the prediction result of the first reference signal resource set through the AI / ML function, and sends the prediction result to the network device.

[0182] For example, if the measurement indication information is used to indicate the measurement of the second reference signal resource set, and the CSI report configuration information is used to indicate the reporting of the measurement results, then the terminal performs a measurement on the second reference signal resource set and sends the measurement results of the second reference signal resource set to the network device.

[0183] The following describes the configuration for reporting measurement results, mainly including the following two scenarios:

[0184] Scenario 1: The first configuration information is CSI resource configuration information

[0185] In some optional embodiments, when the first configuration information is CSI resource configuration information, the CSI resource configuration information is associated with CSI report configuration information, and the CSI report configuration information is used to configure the reporting content corresponding to the first reference signal resource set and / or the second reference signal resource set.

[0186] The CSI report configuration information includes:

[0187] The first parameter, used to indicate the first reported content and the second reported content; or

[0188] The second parameter and the third parameter, wherein the second parameter is used to indicate the first reported content and the third parameter is used to indicate the second reported content;

[0189] Wherein, the first reported content corresponds to the first reference signal resource set, and the second reported content corresponds to the second reference signal resource set.

[0190] For example, a new first parameter is introduced to instruct the terminal to report the first reported content corresponding to Set A and the second reported content corresponding to Set B. For example, the first part of the first parameter is CSI-RS index / SSB-RS index, and the second part of the first parameter is CRI-RSRP / SSB-index-RSRP.

[0191] The pseudocode is as follows:

[0192]

[0193]

[0194] For example, the CSI report configuration information CSI-ReportConfig contains an indication parameter reportQuantity, and an additional reportQuantity2 is introduced into the CSI report configuration information CSI-ReportConfig. Here, the indication parameter reportQuantity corresponds to the first reported content indicating the first reference signal resource set, while the other reportQuantity corresponds to the second reported content indicating the second reference signal resource set; the two reported contents are configured independently. Alternatively, the indication parameter reportQuantity corresponds to the second reported content indicating the second reference signal resource set, while the other reportQuantity corresponds to the first reported content indicating the first reference signal resource set; the two reported contents are configured independently.

[0195] Accordingly, the CSI report sent by the terminal includes a first CSI report and a second CSI report. The first CSI report includes a first reporting content corresponding to the first reference signal resource set, and the second CSI report includes a second reporting content for the second reference signal resource set. The reporting information type / content is independently configured.

[0196] The specific implementation code is shown below:

[0197]

[0198] In the above embodiments, it is possible to simultaneously report the content of the first reference signal resource set and the second reference signal resource set.

[0199] It should be noted that when the terminal only reports the measurement results of the first reference signal resource set or the second reference signal resource set, the existing reporting field reportQuantity can be used, and there is no need to introduce new indication parameters.

[0200] Scenario 2: The first configuration information is the CSI report configuration information.

[0201] In some optional embodiments, when the first configuration information is CSI report configuration information, the CSI report configuration information is also used to configure the reporting content corresponding to the first reference signal resource set and / or the second reference signal resource set.

[0202] Optionally, the CSI report configuration information also includes:

[0203] The first parameter, used to indicate the first reported content and the second reported content; or

[0204] The second parameter and the third parameter, wherein the second parameter is used to indicate the first reported content and the third parameter is used to indicate the second reported content;

[0205] Wherein, the first reported content corresponds to the first reference signal resource set, and the second reported content corresponds to the second reference signal resource set.

[0206] It should be noted that the method of indicating the content to be reported in the CSI report configuration information can be found in the explanation of Case 1, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0207] See Figure 3 This application provides a method for determining association relationships, applied to network devices, including the following steps:

[0208] Step 301: Send first configuration information to the terminal. The first configuration information is used to indicate the association between the first reference signal resource set and the second reference signal resource set. The first configuration information is channel state information (CSI) resource configuration information or CSI report configuration information.

[0209] Accordingly, the terminal learns from the first configuration information that there is a correlation between the first reference signal resource set and the second reference signal resource set, and determines that there is a correlation between the first reference signal resource set and the second reference signal resource set, so that the terminal determines that the measurement results of the first reference signal resource set and the second reference signal resource set are used for the training or inference of the same model when performing beam management.

[0210] Option 1; The first configuration information is CSI resource configuration information.

[0211] In an optional embodiment, when the first configuration information is CSI resource configuration information, the CSI resource configuration information indicates the association between the first reference signal resource set and the second reference signal resource set in the following manner:

[0212] Method 1: The CSI resource configuration information is associated with the first reference signal resource set and the second reference signal resource set.

[0213] In Method 1 above, the network device indicates that the first reference signal resource set and the second reference signal resource set are associated by configuring them in the same CSI resource configuration. Correspondingly, the terminal determines that the first reference signal resource set and the second reference signal resource set are associated through the CSI resource configuration information, and determines that the first reference signal resource set and the second reference signal resource set are CSI-RS resources that enable the same AI / ML model or AI / ML function through the association relationship. Among them, the first reference signal resource set is the CSI-RS resource explicitly configured for the first beam set setA, and the second reference signal resource set is the CSI-RS resource explicitly configured for the second beam set setB.

[0214] Method 2: The CSI resource configuration information is associated with the first reference signal resource set, and the first reference signal resource set indicates the association relationship with the second reference signal resource set through first implicit information.

[0215] It should be noted that the second set of reference signal resources in this method 2 is a subset of the first set of reference signal resources.

[0216] In this method 2, the terminal device obtains the first reference signal resource set corresponding to the first beam set Set A through CSI resource configuration information, and then determines the second reference signal resource set corresponding to the second beam set Set B according to the first implicit indication information. In other words, the CSI-RS resources corresponding to Set B are implicitly configured.

[0217] Optionally, the first implicit indication information includes:

[0218] At least one bitmap corresponding to the first reference signal resource set, wherein the at least one bitmap indicates the distribution of reference signal resources of the second reference signal resource set; or

[0219] The distribution interval and starting offset of the reference signal resources in the second reference signal resource set in the first reference signal resource set.

[0220] Optionally, at least one bitmap corresponding to the first reference signal resource set includes: a first bitmap and / or at least one second bitmap corresponding to the first reference signal resource set;

[0221] The first reference signal resource set is composed of multiple reference signal resource sets. The first bit map is used to indicate whether each of the reference signal resource sets belongs to the candidate resource set of the second reference signal resource set. The second bit map is used to indicate the distribution of reference signal resources belonging to the second reference signal resource set in each of the reference signal resource sets.

[0222] Method 3: The CSI resource configuration information is associated with the second reference signal resource set, and the second reference signal resource set indicates its association with the first reference signal resource set through second implicit information.

[0223] It should be noted that this method 3 is applicable to scenarios where the first reference signal resource set and the second reference signal resource set are different.

[0224] In this method 3, the terminal device obtains the second reference signal resource set corresponding to the second beam set Set B through the CSI resource configuration information, and then determines the first reference signal resource set corresponding to the first beam set Set A according to the second implicit indication information. In other words, the CSI-RS resources corresponding to Set A are implicitly configured.

[0225] Optionally, the second implicit indication information includes: quasi-co-location QCL extension information, used to indicate the quasi-co-location extension relationship between the first reference signal resource set and the second reference signal resource set.

[0226] It should be noted that the implementation principles of methods 1 to 3 above are the same as those of the terminal-side implementation. Please refer to the example description of the terminal-side implementation. To avoid repetition, they will not be repeated here.

[0227] Option 2: The first configuration information is the CSI report configuration information.

[0228] In an optional embodiment, when the first configuration information is CSI report configuration information, the CSI report configuration information indicates the association between the first reference signal resource set and the second reference signal resource set in the following manner:

[0229] Method A: The CSI report configuration information is associated with a first CSI resource configuration and a second CSI resource configuration. The first CSI resource configuration is used to configure the first reference signal resource set, and the second CSI resource configuration is used to configure the second reference signal resource set; or

[0230] Method B: The CSI report configuration information is associated with the first CSI resource configuration and the second reference signal resource set. The first CSI resource configuration is used to configure the first reference signal resource set, and the first reference signal resource set indicates its association with the second reference signal resource set through first implicit information; or

[0231] Optionally, the first implicit indication information includes:

[0232] At least one bitmap corresponding to the first reference signal resource set, wherein the at least one bitmap indicates the distribution of reference signal resources of the second reference signal resource set; or

[0233] The distribution interval and starting offset of the reference signal resources in the second reference signal resource set in the first reference signal resource set.

[0234] Optionally, at least one bitmap corresponding to the first reference signal resource set includes: a first bitmap and / or at least one second bitmap corresponding to the first reference signal resource set;

[0235] The first reference signal resource set is composed of multiple reference signal resource sets. The first bit map is used to indicate whether each of the reference signal resource sets belongs to the candidate resource set of the second reference signal resource set. The second bit map is used to indicate the distribution of reference signal resources belonging to the second reference signal resource set in each of the reference signal resource sets.

[0236] Method C: The CSI report configuration information is associated with the first reference signal resource set and the second CSI resource configuration. The second CSI resource configuration is used to configure the second reference signal resource set, and the second reference signal resource set indicates its association with the first reference signal resource set through second implicit information; or

[0237] Method D: The CSI report configuration information carries the identifier ID of the first reference signal resource set and is associated with the second CSI resource configuration, which is used to configure the second reference signal resource set.

[0238] Optionally, the second implicit indication information includes: quasi-co-location QCL extension information, used to indicate the quasi-co-location extension relationship between the first reference signal resource set and the second reference signal resource set.

[0239] It should be noted that the implementation principles of methods A to D above are the same as those of the terminal-side implementation. Please refer to the example description of the terminal-side implementation. To avoid repetition, they will not be repeated here.

[0240] As an optional embodiment, if the first reference signal resource set or the second reference signal resource set includes multiple reference signal resource sets, and the first condition is met, it is determined that there is an association relationship between the multiple reference signal resource sets.

[0241] The first condition includes at least one of the following:

[0242] The multiple sets of reference signal resources are configured in a single CSI resource configuration information;

[0243] The multiple sets of reference signal resources are configured in a resource list;

[0244] The multiple sets of reference signal resources are configured with the same identifier.

[0245] That is, if the terminal determines that multiple reference signal resource sets in the CSI resource configuration are related by the first condition, it can determine that the multiple reference signal resource sets are used to constitute the first reference signal resource set or the second reference signal resource set.

[0246] For ease of understanding, the association relationship between the first reference signal resource set and the second reference signal resource set can be regarded as the first association relationship, and the association relationship between multiple reference signal resource sets forming the first reference signal resource set or the second reference signal resource set can be regarded as the second association relationship.

[0247] It should be noted that if the same CSI resource configuration information is associated with both the first reference signal resource set and the second reference signal resource set, then the first reference signal resource set and the second reference signal resource set are distinguished by different fields in the CSI resource configuration information.

[0248] In some alternative embodiments, the first configuration information further includes measurement indication information, which is used to indicate whether to perform beam measurement on the first reference signal resource set and / or the second reference signal resource set.

[0249] For example, the network device associates a CSI resource configuration information in the CSI report configuration information. This CSI resource configuration information is associated with a first reference signal resource set corresponding to a first beam set Set A and a second reference signal resource set corresponding to a second beam set Set B. The CSI report configuration information also includes measurement indication information, used to indicate whether to perform beam measurement on the first reference signal resource set and / or the second reference signal resource set; accordingly, the terminal determines the content to be reported based on the measurement indication information.

[0250] For example, the network device associates a first reference signal resource set corresponding to a first beam set Set A and a second reference signal resource set corresponding to a second beam set Set B in the CSI resource configuration information. The CSI resource configuration information also includes measurement indication information to indicate whether beam measurement should be performed on the first reference signal resource set and / or the second reference signal resource set; accordingly, the terminal determines the content to be reported based on the measurement indication information.

[0251] Optionally, the measurement indication information is used to indicate at least one of the following:

[0252] Measure the first reference signal resource set;

[0253] Measure the second reference signal resource set;

[0254] Measure the first reference signal resource set and the second reference signal resource set;

[0255] Measure the second reference signal resource set, and predict the first reference signal resource set based on the second reference signal resource set.

[0256] Optionally, the measurement indication information is used to indicate at least one of the following:

[0257] The first set of reference signal resources is a virtual resource;

[0258] Predict the first set of reference signal resources.

[0259] It should be noted that the explanation of this embodiment is the same as that of the terminal-side embodiment. Please refer to the example description of the terminal-side embodiment. To avoid repetition, it will not be repeated here.

[0260] Scenario 1: The first configuration information is CSI resource configuration information
