Background Art

[0002] Due to the shortage of low-frequency spectrum resources, the millimeter-wave band that provides a wider bandwidth has become an important band for the 5G NR (New Radio) system. Because millimeter waves have a short wavelength, they have different propagation characteristics from the conventional low-frequency band. For example, the propagation loss is high, and the reflection and diffraction performance are poor. Therefore, usually, a larger-scale antenna array is adopted to form a forming beam with a larger gain, overcome the propagation loss, and ensure the coverage of the system. The 5G NR standard has designed a series of schemes such as beam scanning, beam measurement, beam reporting, and beam indication for beam management. However, when the number of transmit and receive beams is large, the load and delay of the system increase significantly.

[0003] With the development of artificial intelligence (AI) technology, applying artificial intelligence technology to the physical layer of wireless communication to solve the difficulties of the conventional method has become one of the current technical directions. In beam management, by using an AI model to predict the spatially optimal beam pair from the results of a small number of beam measurements, the load and delay of the system can be significantly reduced.

[0004] Note that the above description of the background art is only for more clearly and completely explaining the configuration of the present invention, and is for the purpose of making those skilled in the art understand. These configurations should not be construed as well-known technologies to those skilled in the art just because they are described in the background art part of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In conventional beam measurement reporting, the network device configures a reference signal resource set for beam measurement by the terminal device and configures the reporting of the measurement. Here, the reporting configuration includes information on the reference signal resource set that instructs the terminal device to measure the quality of the reference signal in the reference signal resource set and report it to the network device. The terminal device measures the quality of the reference signal according to the configuration of the network device and reports the reporting quantity to the network device, in this case the reporting quantity is the measured quantity obtained by the measurement. Here, the content of the report includes the measured quantity and the reference signal resource instruction corresponding to the measured quantity.

[0006] When an AI model is deployed on the terminal device and a reference signal resource set for beam measurement is configured for the network device, the terminal device can measure the reference signals in the reference signal resource set, obtain the measured quantity, use the measured quantity as input to the AI ​​model, and obtain the predicted quantity. The reported quantity from the terminal device may be the measured quantity and / or the predicted quantity, but if the reported quantity is the predicted quantity, it is necessary to further report a reference signal resource instruction corresponding to the predicted quantity. However, since the reference signal or beam(pair) corresponding to the predicted quantity may not be included in the reference signal resource set for beam measurement, the reference signal resource instruction cannot specify the reference signal or beam(pair) corresponding to the predicted quantity.

[0007] In view of at least one of the above-mentioned problems, embodiments of the present invention provide an information transmission and reception method, apparatus, and communication system. [Means for solving the problem]

[0008] One embodiment of the present invention provides an information transmitting and receiving device applicable to a network device, comprising: a first transmitting unit that transmits reference signal resource set configuration information and report configuration information to a terminal device, wherein the reference signal resource set includes a first reference signal resource set and / or a second reference signal resource set; and a first receiving unit that receives a first report from the terminal device.

[0009] Another embodiment of the present invention provides an information transmission and reception device applied to a terminal device, comprising: a second receiving unit that receives reference signal resource set configuration information and report configuration information transmitted by a network device, wherein the reference signal resource set includes a first reference signal resource set and / or a second reference signal resource set; and a second transmitting unit that transmits a first report to the network device.

[0010] Another embodiment of the present invention provides a communication system including a network device and / or a terminal device, wherein the network device includes the device described in one embodiment above, and the terminal device includes the device described in the other embodiment above.

[0011] One of the advantageous effects of the embodiments of the present invention is as follows. According to the above embodiments, the network device associates a reference signal resource set for measurement with a reference signal resource set for prediction using second instruction information, so that when the terminal device reports a reported quantity, it can accurately indicate the beam (pair) information corresponding to each reported quantity, i.e., the reference signal resource in the reference signal resource set for prediction, thus solving the above problems of the prior art. Alternatively, the terminal device adds third instruction information to the reporting instance, instructing that the reference signal resource corresponding to the reported quantity indicates the corresponding reference signal resource set, so that when the terminal device reports a reported quantity, it can accurately indicate the beam (pair) information corresponding to each reported quantity, i.e., the reference signal resource in the reference signal resource set for prediction, thus solving the above problems of the prior art.

The upper-layer signaling may also be, for example, a MAC (Medium Access Control) signaling, or may be referred to as a MAC CE (MAC control element). However, the present invention is not limited to these.

[0031] The following describes a scenario of an embodiment of the present invention with reference to an example, but the present invention is not limited thereto.

[0032] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present invention, schematically showing examples of terminal devices and network devices. As shown in Figure 1, the communication system 100 may include a network device 101 and terminal devices 102 and 103. For the sake of explanation, Figure 1 is described using two terminal devices and one network device as an example, but embodiments of the present invention are not limited thereto.

[0033] In embodiments of the present invention, existing services or services that can be implemented in the future can be provided between the network device 101 and the terminal devices 102 and 103. For example, these services include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), and related communications for terminal devices with reduced capabilities.

[0034] Here, the terminal device 102 may transmit data to the network device 101 using, for example, a grant or grant-free transmission method. The network device 101 receives the data transmitted by one or more terminal devices 102 and feeds back information to the terminal devices 102, such as acknowledgment (ACK) / non-acknowledgment (NACK) information. Based on the feedback information, the terminal devices 102 may confirm the end of the transmission process, perform a new data transmission, or perform a data retransmission.

[0035] Although Figure 1 shows that both terminal devices 102 and 103 are located within the coverage area of ​​network device 101, the present invention is not limited to this. Neither of the two terminal devices 102 and 103 are located within the coverage area of ​​network device 101, or one terminal device 102 may be located within the coverage area of ​​network device 101 and the other terminal device 103 may be located outside the coverage area of ​​network device 101.

[0036] An AI model (or ML model) includes, but is not limited to, an input layer, multiple convolutional layers, a concatenation layer, a fully connected layer (FC), and a quantizer. Here, the processing results of multiple convolutional layers are merged in the concatenation layer, and the specific configuration of the AI ​​model may be explained by referring to prior art, so the explanation is omitted here.

[0037] 5G and 6G systems define a very wide range of terminal technical features (UE features). Terminal devices are not required to support all of these features. The network understands the capabilities of the UE by querying and reporting the capabilities of the terminal devices, i.e., UE capabilities, and by understanding the support status of the UE functions, providing a basis for subsequent scheduling, configuration, and communication with the terminals.

[0038] To support the diversity of terminal functions, existing standards predefine multiple features for a terminal, each feature further predefines one or more feature groups, and within each feature group, predefines one or more components, defining identifiers or sequence numbers for each feature, feature group, and component. According to current 5G-Advanced and 6G technology trends, if a single terminal device can support multiple AI / ML functions or models, corresponding features or feature groups can be predefinated for each AI / ML function or model.

[0039] When applying an AI / ML model to beam management, for example, beam spatial domain prediction and beam time domain prediction may each be predefined as a single feature, such as an AI / ML feature for beam spatial domain prediction and an AI / ML feature for beam time domain prediction. Alternatively, beam management supporting the AI / ML model may be predefined as a single feature, and one or more feature groups may be predefined for each, such as an AI / ML feature group for beam spatial domain prediction and an AI / ML feature group for beam time series prediction. The present invention does not limit how the AI / ML functions or models are defined as features or feature groups.

[0040] In a function-based lifecycle management process, if a device supports multiple AI / ML functions, one AI / ML function can be defined by one AI / ML feature or one AI / ML feature group.

[0041] In a model-based lifecycle management process, if a device supports multiple AI / ML models, one AI / ML model can be defined by one AI / ML feature or one AI / ML feature group.

[0042] The AI / ML functions or models and related parameters described above can be defined by predefined features or feature groups that are commonly understood when the network side and the terminal side communicate capability information.

[0043] In embodiments of the present invention, a function or model is also referred to as a feature or feature group, and different features or feature groups may include corresponding parameters or applicability conditions. Different features or feature groups may have identifiers (IDs) or corresponding indexes (indexes) or logical identifiers.

[0044] Therefore, if a terminal supports multiple AI / ML functions or models, such functions or models may be distinguished by function and / or model identifiers or logical identifiers, or by feature or feature group identifiers or sequence numbers.

[0045] In a function-based lifecycle management process, a terminal device may be implemented by one AI / ML model or multiple AI / ML models to achieve a certain function, or multiple functions may be implemented by one AI / ML model, and the specific implementation method does not need to be notified to the network device.

[0046] In a feature-based lifecycle management process, if a single feature is implemented by multiple models, the different models may represent different scenarios, different site addresses, different cells, different configurations, different application conditions, etc., as determined by the model training and development process.

[0047] In the following embodiments, the "reference signal," "beam (pair)," and "reference signal resource" may be interchangeable.

[0048] According to the inventors of the present invention, when an AI model is deployed on the terminal device side to make predictions of beam pairs, there are two sets of reference signal resources: a set of reference signal resources for measurement and a set of reference signal resources for prediction. Here, the set of reference signal resources for measurement means a set of reference signals for beam measurement (i.e., a set of reference signal resources corresponding to the measured quantities input to the model), and the set of reference signal resources for prediction means a set of reference signal resources corresponding to the predicted beam quantities (i.e., a set of reference signal resources corresponding to the predicted quantities output by the model).

[0049] For example, there are at least two prediction scenarios: (1) The AI ​​model uses measured values ​​from some beam pairs to output predicted values ​​for all beam pairs, in which case the reference signal resource set for measurement is a subset of the reference signal resource set for prediction. (2) The AI ​​model uses measured values ​​from a wide beam (SSB) to output predicted values ​​for a narrow beam, in which case the reference signal resource set for measurement is a set of SSB signals and the reference signal resource set for prediction is a set of CSI-RS signals, so the reference signal resource set for measurement and the reference signal resource set for prediction are not the same reference signal resource set.

[0050] When a terminal device reports a predicted quantity to a network device, the reference signal resource instruction corresponding to the predicted quantity actually corresponds to the reference signal resource set for prediction, not the reference signal resource set for measurement. However, in the definition of the conventional standard, the reference signal resource instruction is made based on the reference signal resource set for measurement, but the reference signal resource set for measurement and the reference signal resource set for prediction are not the same set. A reference signal corresponding to the predicted quantity may appear, meaning that the beam(s) may not be included in the reference signal resource set for measurement. Therefore, when reporting a predicted quantity, it is not possible to specify the reference signal or beam(s) corresponding to that predicted quantity.

[0051] In view of the above-mentioned problems, the embodiments of the present invention provide an information transmission and reception method and apparatus. The following will be described with reference to the drawings and embodiments.

[0052] <Example 1> Embodiments of the present invention provide an information transmission and reception method, which will be described from the perspective of the network device.

[0053] Figure 2 is a schematic diagram of an example of an information transmission and reception method according to an embodiment of the present invention. As shown in Figure 2, the method includes the following steps.

[0054] Step 201: The network device transmits reference signal resource set configuration information and reporting configuration information to the terminal device, the reference signal resource set including a first reference signal resource set and / or a second reference signal resource set.

[0055] Step 202: The network device receives a first report from the terminal device.

[0056] Figure 2 above merely provides a schematic representation of an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between various steps may be appropriately adjusted, or several other steps may be added, or several steps may be removed. Those skilled in the art can make appropriate modifications based on the above description and are not limited to the description in Figure 2 above.

[0057] In some embodiments, a network device may configure multiple reference signal resource sets for a terminal device, where the multiple reference signals may be reference signals such as CSI-RS and / or SSB. For example, a configured reference signal resource set is a list of reference signals, and each reference signal resource set consists of one or more reference signals. In other words, a network device may transmit reference signal resource set configuration information to a terminal device, where the reference signal resource set configuration information includes a configuration identifier for one or more reference signal resource sets and identifiers for one or more reference signals that make up the reference signal resource sets.

[0058] For example, if the reference signal is SSB, the reference signal resource set configuration information can be carried using the SSB resource set configuration information element CSI-SSB-ResourceSet, which includes the identifier csi-SSB-ResourceSetId of the reference signal resource set. For example, if the reference signal is CSI-RS, the reference signal resource set configuration information can be carried using the non-zero power CSI-RS resource set configuration information element NZP-CSI-RS-ResourceSet, which includes the identifier nzp-CSI-ResourceSetId of the reference signal resource set. Alternatively, the reference signal resource set configuration information can be carried using the information element CSI-ResourceConfig, which includes the configuration information of one or more reference signal resource sets. The data format of each information element may be described by reference to related technologies, and other examples are omitted here, and embodiments of the present invention are not limited thereto.

[0059] In some embodiments, in addition to reference signal resource set configuration information, the network device may further transmit report configuration information to the terminal device. The report configuration information (e.g., carried using the information element CSI-ReportConfig) may include report configuration identification information, a report configuration type including three types: periodic, semi-periodic / semi-PersistentOnPUCCH / semi-PersistentOnPUSCH, and aperiodic, a quantity type (e.g., L1-RSRP (L1 Reference Signal Receiving Power) or L1-SINR (L1 Signal to Interference plus Noise Ratio)), and a reference signal resource set configuration identifier. The reference signal resource set configuration identifier corresponds to one or more reference signal resource set identifiers in the reference signal resource set configuration information.

[0060] The above-described reference signal resource set configuration and reporting configuration may further include other information, details of which can be found in the relevant technologies, and embodiments of the present invention are not limited thereto.

[0061] In some embodiments, the reference signal resource set configuration information includes a first reference signal resource set and / or a second reference signal resource set, the first of which can be used for beam measurement and the second of which can be used for beam prediction. That is, the first reference signal resource set is a reference signal resource set for measurement and the second of which is a reference signal resource set for prediction. Alternatively, the second reference signal resource set can be used for beam measurement and the first of which can be used for beam prediction. That is, the second reference signal resource set is a reference signal resource set for measurement and the first of which is a reference signal resource set for prediction. Embodiments of the present invention are not limited thereto, and the first and second reference signal resource sets may also be used for other beam management functions, which will not be described here. The first and second reference signal resource sets may be CSI-RS reference signal resource sets and / or SSB reference signal resource sets.

[0062] In some embodiments, to facilitate the identification of the uses of the above-described reference signal resource set, the network device may further transmit first instruction information to the terminal device. The first instruction information indicates that the first reference signal resource set is used at least for beam measurement or for beam prediction. The first instruction information may be carried by radio resource control signaling (RRC), media access control (MAC) control elements (CE), or downlink control information (DCI). The above-described RRC, MAC CE, or DCI may be existing or newly added, and for example, this first instruction information may be carried by the above-described reference signal resource set configuration information element or reporting configuration information element. Embodiments of the present invention are not limited thereto.

[0063] For example, this first instruction information may be a single bit of information added to the reference signal resource set configuration information element. If the bit value of this single bit is 1, it indicates that the first reference signal resource set configured in the reference signal resource set configuration information element is a reference signal resource set for beam prediction, and if the bit value is 0, it indicates that the first reference signal resource set configured in the reference signal resource set configuration information element is a reference signal resource set for beam prediction. The reverse may also be true.

[0064] For example, this first instruction information may be a single bit of information added to the report configuration information element. If the bit value of this single bit is 1, it indicates that the first reference signal resource set configured in the report configuration information element is a reference signal resource set for beam measurement; if the bit value is 0, it indicates that the first reference signal resource set configured in the reference signal resource set configuration information element is a reference signal resource set for beam prediction. The reverse may also be true.

[0065] The above is merely an illustrative explanation, and new signaling could be designed to carry this first instruction information; other examples are omitted here.

[0066] In some embodiments, a relationship between a first and second reference signal resource set may be established between the terminal device and the network device through additional signaling. More specifically, the network device may configure relational information for the two reference signal resource sets required for the terminal device's AI model. This will be explained in detail below.

[0067] In some embodiments, a network device transmits a second instruction information to a terminal device, the second instruction information indicating one or more second reference signal resource sets. One or more second reference signal resource sets are associated with a first reference signal resource set. Here, the association of one or more second reference signal resource sets with a first reference signal resource set indicates that one or more second reference signal resource sets are related to (or correspond to, match, or paired with) the first reference signal resource set. That is, the second instruction information may indicate one or more reference signal resource sets for prediction associated with a reference signal resource set for measurement, or the second instruction information may indicate one or more reference signal resource sets for measurement associated with a reference signal resource set for prediction. This establishes a correspondence (association, match, or pairing) between the reference signal resource sets for measurement and the reference signal resource sets for prediction. For example, the reference signal resource set for measurement and the reference signal resource set for prediction correspond to the inputs and outputs of the AI ​​model on the terminal device side, respectively, and the association between the reference signal resource set for measurement and the reference signal resource set for prediction (the first reference signal resource set and the second reference signal resource set) means that the reference signal resource set for measurement and the reference signal resource set for prediction correspond to the inputs and outputs of a single AI model. In other words, if the reference signal resource set for measurement and the reference signal resource set for prediction correspond to the inputs and outputs of a single AI model, then the reference signal resource set for measurement and the reference signal resource set for prediction are related (associated, corresponding, matching, or paired).

[0068] In some embodiments, the same second reference signal resource set (having the same number and identifier) ​​may be associated with different first reference signal resource sets, or different second reference signal resource sets (having different numbers and / or different identifiers), and the embodiments of the present invention are not limited thereto. The following describes how to determine which reference signal resource set (fourth reference signal resource set) may (can) be associated with the first reference signal resource set.

[0069] In some embodiments, one or more (N) fourth reference signal resource sets associated with a first reference signal resource set are obtained from at least terminal device features / feature groups or terminal device capability reports. One or more (M) second reference signal resource sets are some (M is less than N) or all (M=N) of the one or more (N) fourth reference signal resource sets, where M and N are integers of 1 or greater. That is, the first reference signal resource set obtained from terminal device features / feature groups or terminal device capability reports may be associated with N fourth reference signal resource sets. If the second reference signal resource sets are indicated using second instruction information, then, according to the implementation algorithm, M fourth reference signal resource sets may be selected or configured from the N fourth reference signal resource sets as M second reference signal resource sets associated with the first reference signal resource set.

[0070] In some embodiments, if the parameters of one or more AI models and / or functions are defined by a set of features / characteristics of a terminal device or in a terminal capability report, the network device obtains the corresponding model parameters (e.g., input / output dimensions of the AI ​​model, pattern of reference signal resource set for measurement, etc.) and then determines, based on the model parameters, whether different reference signal resource sets are correlateable, i.e., available as inputs and outputs of the AI ​​model.

[0071] For example, if the terminal device has two AI models, with one AI model having an input dimension of 16 and an output dimension of 64, and the other AI model having an input dimension of 16 and an output dimension of 128, then for a reference signal resource set with dimension 16 (reference signal resource set for measurement, first reference signal resource set), the associated reference signal resource sets (fourth reference signal resource set), obtained from the terminal device's features / feature set or terminal device capability report, are the reference signal resource sets with dimensions 64 and 128 (reference signal resource set for prediction). The network device may select or configure reference signal resource sets with dimensions 64 and 128 (all fourth reference signal resource sets) as two second reference signal resource sets associated with the first reference signal resource set, or, according to the implementation algorithm (for example, if the network device expects better prediction accuracy from the AI ​​model for beam prediction of terminal devices), it may select or configure a reference signal resource set with dimension 64 from the two fourth reference signal resource sets as one second reference signal resource set associated with the first reference signal resource set.

[0072] For example, if the terminal device has two AI models, with one AI model having an input dimension of 16 and an output dimension of 64, and the other AI model having an input dimension of 32 and an output dimension of 64, then for a reference signal resource set of dimension 64 (reference signal resource set for prediction, first reference signal resource set), the associated reference signal resource set (fourth reference signal resource set), obtained from the terminal device's features / feature set or terminal device capability report, would be a reference signal resource set with dimensions 16 and 32 (reference signal resource set for measurement). The network device may select or configure reference signal resource sets with dimensions 16 and 32 (all fourth reference signal resource sets) as two second reference signal resource sets associated with the first reference signal resource set, or, according to an implementation algorithm (for example, if the terminal device expects its beam prediction model to be able to further reduce the reference signal load), it may select or configure a reference signal resource set with dimension 16 from the two fourth reference signal resource sets as one second reference signal resource set associated with the first reference signal resource set.

[0073] In some embodiments, this second instruction information may be carried by radio resource control signaling (RRC), media access control (MAC) control elements (CE), or downlink control information (DCI). The RRC, MAC CE, or DCI may be existing or novel, and embodiments of the present invention are not limited thereto. For example, this second instruction information may be carried by the reference signal resource set configuration information element or reporting configuration information element described above. The following is an illustrative example.

[0074] For example, a network device may add second instruction information to a reference signal resource set configuration information element in order to establish an association between a first reference signal resource set and a second reference signal resource set. For example, in the information element CSI-SSB-ResourceSet, the identifier csi-SSB-ResourceSetId of an existing reference signal resource set can be considered as the identifier of the first reference signal resource set, and the second instruction information is added to the information element CSI-SSB-ResourceSet relating to one or more second reference signal resource sets, which may be CSI-RS reference signal resource sets. Alternatively, in the information element NZP-CSI-RS-ResourceSet, the identifier nzp-CSI-ResourceSetId of an existing reference signal resource set can be considered as the identifier of the first reference signal resource set, and in NZP-CSI-RS-ResourceSet, second instruction information relating to one or more second reference signal resource sets, which may be SSB reference signal resource sets or CSI-RS reference signal resource sets, can be added. Alternatively, in the information element CSI-ResourceConfig, the reference signal resource set list csi-RS-ResourceSetList can be considered as one or more first reference signal resource sets, and in CSI-SSB-ResourceSet, one or more second instruction information can be added to indicate one or more second reference signal resource sets, each of which may be an SSB reference signal resource set or a csi-SSB-ResourceSetId reference signal resource set, that are associated with one or more first reference signal resource sets. In the above example, if multiple first reference signal resource sets are configured, second instruction information can be added to the configuration of each first reference signal resource set to indicate that one or more second reference signal resource sets are associated with each first reference signal resource set.

[0075] For example, a network device may add this second instruction information to a reporting configuration information element in order to establish an association between a first reference signal resource set and a second reference signal resource set. In the reporting configuration information element, the configuration identifier of an existing reference signal resource set can be considered as the configuration identifier of the first reference signal resource set, and the second instruction information can be added to associate one or more second reference signal resource sets, which may be SSB reference signal resource sets or CSI-RS reference signal resource sets.

[0076] The above is merely one example, and further new signaling could be designed to carry this second instruction information; other examples will not be discussed here.

[0077] In some embodiments, this second instruction information is at least a configuration identifier or identifier of a reference signal resource set, or a bitmap. The following is an illustrative example.

[0078] For example, this second instruction information may be represented using a configuration identifier or identifier of a reference signal resource set, where the identifier is a configuration identifier or identifier of a reference signal resource set within a reference signal resource set configuration information element, such as NZP-CSI-RS-RourceSetId or CSI-SSB-ResourceSetId, and this second instruction information may be one or more configuration identifiers or identifiers of a second reference signal resource set. For example, this second instruction information may be represented using a bitmap, the length of which relates to the maximum number of configured reference signal resource sets. For example, the length (number of bits) of the bitmap is equal to the maximum number of configured reference signal resource sets, each bit corresponds to one reference signal resource set (for example, the position or sequence number of a bit in the bitmap corresponds to the identifier of a reference signal resource set), and the bit values ​​of the bitmap are used to indicate whether the corresponding reference signal resource set is a second reference signal resource set, i.e., each bit value is used to indicate whether the corresponding reference signal resource set is a second reference signal resource set related to a first reference signal resource set. For example, if a bit value is a first specific value, it indicates that the corresponding reference signal resource set is the associated second reference signal resource set, and if a bit value is a second specific value, it indicates that the corresponding reference signal resource set is not the associated second reference signal resource set. Which bit is set to the first specific value can be determined based on the identifier of the second reference signal resource set. For example, if the identifier of the second reference signal resource set is 1, 3, and 5, then the bit values ​​corresponding to the bits at positions 2, 4, and 6 in the bitmap are the first specific value. For example, the first specific value may be 1 and the second specific value may be 0, or the first specific value may be 0 and the second specific value may be 1, and the embodiments of the present invention are not limited thereto.If the bitmap contains multiple first specific values, it indicates that the first reference signal resource set is associated with multiple second reference signal resource sets; if the bitmap contains one first specific value, it indicates that the first reference signal resource set is associated with one second reference signal resource set.

[0079] In some embodiments, if the first reference signal resource set is an SSB reference signal resource set, then one or more associated second reference signal resource sets are CSI-RS reference signal resource sets, i.e., the first and second reference signal resource sets are different types of reference signal resource sets; or, if the first reference signal resource set is a CSI-RS reference signal resource set, then one or more associated second reference signal resource sets are SSB reference signal resource sets, i.e., the first and second reference signal resource sets are different types of reference signal resource sets; or, if the first reference signal resource set is a CSI-RS reference signal resource set, then one or more associated second reference signal resource sets are CSI-RS reference signal resource sets, and the first and second reference signal resource sets are the same type of reference signal resource set. As described above, if the first and second reference signal resource sets correspond to different sets, and the first and second reference signal resource sets are of the same type, then the identifiers of the two reference signal resource sets will be different and they can be distinguished by their identifiers. However, if the first and second reference signal resource sets are of different types, then the identifiers of the two reference signal resource sets may be the same. In other words, if two types of reference signal resource sets are configured for a network device, then if the second reference signal resource set is indicated based on the identifier of the reference signal resource set, it is not possible to determine which type of reference signal resource set that identifier corresponds to. Therefore, in embodiments of the present invention, the network device may or may not transmit the fourth instruction information to the terminal device. The fourth instruction information indicates that the type of reference signal in the second reference signal resource set is the same as or different from the type of reference signal in the first reference signal resource set, and the type of reference signal is CSI-RS or SSB.Alternatively, the fourth instruction information is used to indicate that the type of reference signal in the second reference signal resource set is SSB or CSI-RS. The fourth instruction information can be carried by radio resource control signaling (RRC), media access control (MAC) control elements (CE), or downlink control information (DCI), the RRC, MAC CE, or DCI may be existing or additional, and for example, the fourth instruction information may be carried by the same information elements as the second instruction information or by different information elements. Embodiments of the present invention are not limited thereto.

[0080] In some embodiments, if the network device does not transmit the fourth instruction information, the reference signals in the second reference signal resource set and the reference signals in the first reference signal resource set indicate the same type of reference signal. If the network device transmits the fourth instruction information, it indicates that the type of reference signal in the second reference signal resource set and the type of reference signal in the first reference signal resource set are different. This allows the type of reference signal in the second reference signal resource set to be indicated. The reverse is also true.

[0081] In some embodiments, the network device transmits a fourth instruction information, which is represented by a single bit. A bit value of 1 indicates that the type of reference signal in the second reference signal resource set is SSB, and a bit value of 0 indicates that the type of reference signal in the second reference signal resource set is CSI-RS. The reverse is also true.

[0082] For example, a network device configures N1 SSB reference signal resource sets for terminal devices, with CSI-SSB-ResourceSetId values ​​ranging from 0 to N1-1. The network device also configures N2 NZP CSI-RS reference signal resource sets for terminal devices, with NZP-CSI-RS-ResourceSetId values ​​ranging from 0 to N2-1. The reference signal resource set configuration of the CSI-RS reference signal resource set with ID 0 further includes a second and a fourth instruction. If the second instruction is {1, 3, 5} and the bit value of the fourth instruction is 0, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the SSB reference signal resource sets with IDs 1, 3, and 5 (the second reference signal resource set). Alternatively, the reference signal resource set configuration of the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) further includes a second instruction. If the second instruction information is {1, 3, 5}, it does not include the fourth instruction information, indicating that the second reference signal resource set is of the same type as the first reference signal resource set; that is, the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the CSI-RS reference signal resource set with IDs 1, 3, 5 (the second reference signal resource set). Further explanation of other examples is omitted here.

[0083] Alternatively, the reference signal resource set configuration of the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) further includes second instruction information. If the second instruction information is {1, 3, 5} and the bit value of the fourth instruction information is 0, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the CSI-RS reference signal resource set with IDs 1, 3, 5 (the second reference signal resource set). If the bit value of the fourth instruction information is 1, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the SSB reference signal resource set with IDs 1, 3, 5 (the second reference signal resource set). Further explanation of other examples is omitted here.

[0084] For example, the reported configuration information for a CSI-RS reference signal resource set with ID 0 includes a second and a fourth instruction. If the second instruction is a bitmap {0000 0000 0010 1010} and the bit value of the fourth instruction is 0, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the SSB reference signal resource sets with IDs 1, 3, and 5 (the second reference signal resource sets). Other examples are omitted here. Alternatively, the reported configuration information for a CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) may further include a second instruction. If the second instruction information is a bitmap {0000 0000 0010 1010}, it does not contain the fourth instruction information, indicating that the second reference signal resource set is of the same type as the first reference signal resource set, i.e., the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the CSI-RS reference signal resource sets with IDs 1, 3, and 5 (the second reference signal resource set). Further explanation of other examples is omitted here.

[0085] Alternatively, the reported configuration information for a CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) further includes second instruction information. If the second instruction information is {0000 0000 0010 1010} and the bit value of the fourth instruction information is 0, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the CSI-RS reference signal resource sets with IDs 1, 3, and 5 (the second reference signal resource set). If the bit value of the fourth instruction information is 1, it indicates that the CSI-RS reference signal resource set with ID 0 (the first reference signal resource set) is associated with the SSB reference signal resource sets with IDs 1, 3, and 5 (the second reference signal resource set). Further explanation of other examples is omitted here.

[0086] For example, in scenario (1) where the AI ​​model outputs predicted quantities for all beams (pairs) based on the measured quantities of some beams (pairs), the NZP-CSI-RS-RourceSet in the report configuration information element may be used as the first reference signal resource set, or second instruction information may be added indicating one or more reference signal resource sets (second reference signal resource sets) for predictions associated with this first reference signal resource set. The second instruction information may be configuration identifiers for one or more NZP-CSI-RS-RourceSets (which may further include a fourth instruction information) configured in the reference signal arrangement information element.

[0087] For example, in scenario (1), if the AI ​​model outputs predicted quantities for all beams (pairs) based on measured quantities for some beams (pairs), a second instruction information may be added to the reference signal resource set configuration for each NZP-CSI-RS-RourceSet (first reference signal resource set) in the reference signal resource set configuration information element, indicating a second reference signal resource set associated with the first reference signal resource set, wherein the second instruction information indicates identifiers for one or more NZP-CSI-RS-RourceSets (which may further include a fourth instruction information). Alternatively, a first instruction information may be added to the reference signal resource set configuration information element indicating that the first reference signal resource set is used for beam measurement or beam prediction.

[0088] For example, in scenario (2), if the AI ​​model outputs a narrow beam prediction quantity based on a broad beam (SSB) measurement quantity, the CSI-SSB-ResourceSet in the reporting configuration information element may be the first reference signal resource set, and a second instruction information may be added indicating a second reference signal resource set associated with this first reference signal resource set, the second instruction information indicating one or more NZP-CSI-RS-RourceSetId (which may further include a fourth instruction information).

[0089] For example, in scenario (2), when the AI ​​model outputs a narrow beam prediction quantity for a broad beam (SSB) measurement quantity, a second instruction information may be added to the reference signal resource set configuration for each CSI-SSB-ResourceSet (first reference signal resource set) in the reference signal resource set configuration information element, indicating a second reference signal resource set associated with this first reference signal resource set, the second instruction information indicating a configuration identifier of one or more NZP-CSI-RS-RourceSets (which may further include a fourth instruction information).

[0090] In some embodiments, upon receiving the above-described reference signal resource set configuration and report configuration, the terminal device performs beam measurements and beam predictions using an AI model. That is, it measures the signals of the reference signal resource set for measurement, obtains the measured quantities, inputs these measured quantities into an AI model deployed on the terminal device side, and obtains the predicted quantities. The measured and predicted quantities may be L1-RSRP or L1-SINR. The terminal device may generate a first report based on at least a first instruction information and / or a second instruction information and / or a fourth instruction information, and transmit the first report to the network device. The first report is a report instance. The first report includes one or more reported quantities, or includes one or more reported quantities and a reference signal resource indicator corresponding to the reported quantities, where the reported quantities are obtained from measurements and / or predictions, i.e., the reported quantities are measured quantities and / or predicted quantities. The reference signal resource indicator includes a synchronous signal block resource indicator (SSB RI) or a channel state information reference signal resource indicator (CRI). A reference signal resource instruction corresponds to the second reference signal resource set and / or the first reference signal resource set. That is, the reference signal corresponding to the reference signal resource instruction belongs to the second reference signal resource set and / or the first reference signal resource set.

[0091] In some embodiments, the first report may or may not include one or more third and / or fifth directive information. The third directive information indicates a third reference signal resource set, and the reference signal resource directive corresponds to the third reference signal resource set. The third reference signal resource set is one of one or more second reference signal resource sets, specifically the second and / or first reference signal resource set. That is, the third directive information is used to indicate the third reference signal resource set to which the reference signal corresponding to the reference signal resource directive belongs. The fifth directive information is used to indicate that the type of reference signal in the third reference signal resource set is SSB or CSI-RS. The third directive information is at least an identifier or bitmap of the reference signal resource set, and a specific embodiment may refer to the second directive information, the difference being that the bitmap has only one bit set to a first specific value. Embodiments of the fifth directive information may refer to the fourth directive information. The third instruction information and / or the fifth instruction information may be carried by the uplink control information UCI, and the fifth instruction information and the third instruction information correspond one-to-one. In the following example, the first reference signal resource set is configured as a reference signal resource set for measurement in the reporting configuration information, and the second reference signal resource set associated with the first reference signal resource set is a reference signal resource set for prediction.

[0092] In some embodiments, when one second reference signal resource set is associated with one first reference signal resource set, the first report does not need to include third indicator information; that is, the reference signal in which reference signal resource set the indicated reference signal belongs can be determined by the reference signal resource indication in the first report. For example, if the first report includes only a measured quantity, the reference signal resource indication corresponding to that measured quantity corresponds to the first reference signal resource set; that is, the reference signal corresponding to the reference signal resource indication (indicator) corresponding to that measured quantity belongs to the reference signal resource set for measurement (the first reference signal resource set). For example, if the first report includes only a predicted quantity, the reference signal associated with the first reference signal resource set is one second reference signal resource set, and the second reference signal resource set is uniquely determined from those known from this second indicator information and / or fourth indicator information. The reference signal resource indication corresponding to the predicted quantity corresponds to a second set of reference signal resources, meaning that the reference signal corresponding to the reference signal resource indication for the predicted quantity belongs to a set of reference signal resources for prediction (a related second set of reference signal resources), and there is no need to indicate the set of reference signal resources to which the reference signal corresponding to the predicted quantity belongs by additional third indication information. If the first report includes both the measured quantity and the predicted quantity, this first report may further include third indication information. When the first report includes both a measured quantity and a predicted quantity, the third reference signal resource set indicated by the third instruction information corresponding to the reference signal resource instruction corresponding to the measured quantity is the first reference signal resource set, and the reference signal corresponding to the reference signal resource instruction corresponding to this measured quantity belongs to the reference signal resource set for measurement (the first reference signal resource set). The third reference signal resource set indicated by the third instruction information corresponding to the reference signal resource instruction corresponding to this predicted quantity is a second reference signal resource set, that is, the reference signal corresponding to the reference signal resource instruction corresponding to this predicted quantity belongs to the reference signal resource set for prediction (the associated second reference signal resource set).Preferably, the first report may further include fifth indication information indicating that the type of reference signal in the third reference signal resource set is SSB or CSI-RS. This avoids the inability to distinguish the corresponding reference signal resource sets when the reference signal resource indications corresponding to the predicted quantity and the measured quantity are the same.

[0093] In some embodiments, if a first reference signal resource set is associated with multiple second reference signal resource sets, the first report may or may not further include one or more third and / or fifth instruction information.

[0094] For example, if the first report contains only a measured quantity, the reference signal resource indication corresponding to that measured quantity corresponds to the first reference signal resource set, meaning the reference signal corresponding to the reference signal resource indication for that measured quantity belongs to the reference signal resource set for measurement (the first reference signal resource set), and there is no need to include third indication information in the first report. If the first report contains only a predicted quantity, since the first reference signal resource set has multiple second reference signal resource sets associated with it, the third indication information needs to further indicate which reference signal resource set for prediction (the third reference signal resource set, or which of the multiple second reference signal resource sets) the reference signal corresponding to the reference signal resource indication for that predicted quantity belongs to. When the first report includes both a measured quantity and a predicted quantity, the third reference signal resource set indicated by the third instruction information corresponding to the reference signal resource instruction corresponding to the measured quantity is the first reference signal resource set, and the reference signal corresponding to the reference signal resource instruction corresponding to the measured quantity belongs to the reference signal resource set for measurement (the first reference signal resource set). The third reference signal resource set indicated by the third instruction information corresponding to the reference signal resource instruction corresponding to the predicted quantity is a second reference signal resource set, that is, the reference signal corresponding to the reference signal resource instruction corresponding to the predicted quantity belongs to the reference signal resource set for prediction (the associated second reference signal resource set). Preferably, the first report may further include fifth instruction information indicating that the reference signal type in the third reference signal resource set is SSB or CSI-RS. This avoids the situation where the corresponding reference signal resource sets become indistinguishable when the reference signal resource instruction corresponding to the predicted quantity and the measured quantity is the same.

[0095] In some embodiments, the first report includes one third instruction piece, and all reference signal resource instructions within the first report correspond to a third set of reference signal resources indicated by the third instruction piece.

[0096] For example, if the first report contains only one predicted quantity, that single predicted quantity corresponds to a reference signal resource set for one prediction, and a third instruction piece indicates the reference signal resource set for the prediction (the third reference signal resource set) to which the reference signal corresponding to the reference signal resource instruction that the single predicted quantity corresponds belongs.

[0097] For example, if the first report contains only multiple predicted quantities, those multiple predicted quantities may correspond to a reference signal resource set for a single prediction. For instance, in the inference process of an AI model, the predicted quantity of the AI ​​model's output corresponds to a beam (pair) corresponding to a reference signal resource set for a single prediction. Therefore, the reference signal resource set for a prediction (a third reference signal resource set) to which the reference signals corresponding to the reference signal resource indications for all predicted quantities belong can be represented collectively by a single third indication. As shown in Table 1 below, if the first report includes four beams (pairs), i.e., four SSB-RI / CRIs, each beam (pair) corresponds to one reported quantity, where the reported quantity corresponding to SSB-RI / CRI#1 is RSRP#1, the reported quantity corresponding to SSB-RI / CRI#2 is RSRP#2, the reported quantity corresponding to SSB-RI / CRI#3 is RSRP#3, and the reported quantity corresponding to SSB-RI / CRI#4 is RSRP#4, and all four reported quantities are predicted quantities, and these four predicted quantities correspond to one reference signal resource set for prediction, then Table 1 includes one third instruction information, which indicates one second reference signal resource set (reference signal resource set for prediction), and the reference signals corresponding to the four SSB-RI / CRIs belong to one second reference signal resource set.

[0098] [Table 1] In some embodiments, the first report includes multiple (Y) third instruction pieces, where one third instruction piece indicates one third reference signal resource set. One or more (Z) reference signal resource instructions in the first report correspond to the third reference signal resource set indicated by one third instruction piece.

[0099] For example, if the first report includes one predicted quantity and one or more measured quantities, the one predicted quantity corresponds to a reference signal resource set for one prediction, and one third instruction piece indicates the reference signal resource set for the prediction to which the reference signal corresponding to the reference signal resource instruction for that one predicted quantity belongs (the third reference signal resource set is one second reference signal resource set), and another third instruction piece indicates the reference signal resource set for the measurement to which the reference signal of the reference signal resource instruction corresponding to that one or more measured quantities belongs (the third reference signal resource set is the first reference signal resource set). Preferably, the fifth instruction piece may indicate that the reference signal type in the third reference signal resource set is SSB or CSI-RS.

[0100] For example, if the first report includes multiple predicted quantities, the multiple (X) predicted quantities may correspond to multiple (Y) reference signal resource sets for prediction, where X is greater than or equal to Y. For example, in the AI ​​model monitoring process, if the terminal device supports multiple beam prediction models and / or functions, different AI models and / or functions can use the same reference signal resource set for measurement to measure the reference signal quantity and obtain predicted quantities for beams (pairs) corresponding to the same or different dimensional reference signal resource sets for prediction. Since the first report includes predicted quantities for multiple functions and / or models, multiple (Y) third instruction pieces must indicate, for each model and / or function, the reference signal resource set for prediction (third reference signal resource set) to which the reference signal corresponding to the reference signal resource instruction corresponding to each predicted quantity belongs.

[0101] As shown in Table 2 below, one third instruction piece indicates a reference signal resource set for prediction (a third reference signal resource set) to which the reference signal corresponding to the reference signal resource instruction for one predicted quantity belongs. The first report includes four beams (pairs), i.e., four SSB-RI / CRIs, each beam (pair) corresponding to one reported quantity, with the reported quantity corresponding to SSB-RI / CRI#1 being RSRP#1, the reported quantity corresponding to SSB-RI / CRI#2 being RSRP#2, the reported quantity corresponding to SSB-RI / CRI#3 being RSRP#3, and the reported quantity corresponding to SSB-RI / CRI#4 being RSRP#4. All four reported quantities are predicted quantities, and the reference signals corresponding to the reference signal resource instructions for the four predicted quantities belong to the same or different reference signal resource sets for prediction. Table 2 includes four third instruction pieces, each indicating a third reference signal resource set (a reference signal resource set for prediction) corresponding to one predicted quantity of a function and / or model.

[0102] [Table 2] For example, if the first report includes one or more measured quantities and multiple predicted quantities, the one or more measured quantities may correspond to one reference signal resource set for measurement, and the multiple (X) predicted quantities may correspond to multiple (Y) reference signal resource sets for prediction, where X is greater than or equal to Y. Therefore, multiple (Y) third directional information is required to indicate, for each model and / or function, the reference signal resource set for prediction to which the reference signal corresponding to the reference signal resource indication corresponding to each predicted quantity belongs (the third reference signal resource set is the second reference signal resource set), and one or more third directional information is required to indicate the reference signal resource set for measurement to which the reference signal corresponding to the reference signal resource indication corresponding to one or more measured quantities belongs (the third reference signal resource set is the first reference signal resource set). Preferably, a fifth directional information may be further used to indicate that the type of reference signal in the third reference signal resource set is SSB or CSI-RS.

[0103] As shown in Table 3 below, RSRP#1 and #2 are measured quantities, RSRP#3 and #4 are predicted quantities, and Table 2 includes four third indication pieces indicating one third reference signal resource set (a reference signal resource set for prediction). Here, the reference signals corresponding to SSB-RI / CRI#3 and 4 belong to the reference signals in the same or different third reference signal resource set (one second reference signal resource set) indicated by the corresponding third indication piece, and the reference signals corresponding to SSB-RI / CRI#1 and 2 belong to the reference signals in the same third reference signal resource set (first reference signal resource set) indicated by the corresponding third indication piece. As a difference from Table 2, preferably, the first report may further include a fifth indication piece that corresponds one-to-one with the third indication piece to indicate that the reference signal type in the third reference signal resource set is SSB or CSI-RS.

[0104] [Table 3] For example, one third instruction information indicates a third reference signal resource set to which reference signals corresponding to reference signal resource indications corresponding to multiple (Z) measured or predicted quantities belong. As shown in Table 4 below, if the first report includes four beams (pairs), i.e., four SSB-RI / CRIs, each beam (pair) corresponding to one reported quantity, with the reported quantity corresponding to SSB-RI / CRI#1 being L1-RSRP#1, the reported quantity corresponding to SSB-RI / CRI#2 being L1-RSRP#2, the reported quantity corresponding to SSB-RI / CRI#3 being L1-RSRP#3, the reported quantity corresponding to SSB-RI / CRI#4 being L1-RSRP#4, and all four reported quantities are predicted quantities, and these four predicted quantities correspond to reference signal resource sets for two different predictions, then Table 4 shows two third instruction information. This includes a third instruction piece that indicates a third reference signal resource set (a reference signal resource set for prediction, a second reference signal resource set) corresponding to two reference signal resource instructions, i.e., SSB-RI / CRI#1 and #2 correspond to the same reference signal resource set for prediction, or the reference signals indicated by SSB-RI / CRI#1 and #2 both belong to one reference signal resource set for prediction, SSB-RI / CRI#3 and #4 correspond to the same reference signal resource set for prediction, or the reference signals indicated by SSB-RI / CRI#3 and #4 both belong to other reference signal resource sets for prediction.

[0105] [Table 4] Alternatively, as shown in Table 5 below, the difference from Table 4 is that RSRP#1 and #2 are measured quantities, RSRP#3 and #4 are predicted quantities, Table 5 has two third indicator pieces, each third indicator piece indicates one third reference signal resource set, and the third reference signal resource set indicated by the third indicator piece corresponding to SSB-RI / CRI#1 and #2 is the first reference signal resource set, and SSB-RI / CRI#1 and #2 correspond to the same reference signal resource set for the same measurement. That is, the reference signals shown in SSB-RI / CRI#1 and #2 all belong to one reference signal resource set for measurement, and the third reference signal resource set indicated by one third indication information corresponding to SSB-RI / CRI#3 and #4 is one second reference signal resource set, and SSB-RI / CRI#3 and #4 belong to the same reference signal resource set for prediction, i.e., the reference signals shown in SSB-RI / CRI#3 and #4 belong to one reference signal resource set for prediction. Another difference from Table 4 is that, preferably, the first report may further include a fifth indication information that corresponds one-to-one with the third indication information to indicate that the type of reference signal in the third reference signal resource set is SSB or CSI-RS.

[0106] [Table 5] For example, one third instruction piece indicates a third reference signal resource set to which reference signals belong that correspond to reference signal resource instructions corresponding to multiple (Z) predicted quantities. In this example, the first report further includes a group identifier corresponding to each reported quantity, i.e., reports may be grouped. For example, as shown in Table 6 below, the first report includes four beams (pairs), i.e., four SSB-RI / CRIs, each corresponding to one reported quantity. The reported quantity corresponding to SSB-RI / CRI#1 is L1-RSRP#1, the reported quantity corresponding to SSB-RI / CRI#2 is L1-RSRP#2, the reported quantity corresponding to SSB-RI / CRI#3 is L1-RSRP#3, and the reported quantity corresponding to SSB-RI / CRI#4 is L1-RSRP#4, and all four reported quantities are predicted quantities, and these four predicted quantities correspond to reference signal resource sets for two different predictions. Table 6 includes two third instruction pieces, each of which indicates a third reference signal resource set (reference signal resource set for prediction) corresponding to a reference signal resource instruction corresponding to a single predicted quantity. That is, if RSRP#1 and #3 are one group, one third instruction piece is used to indicate the third reference signal resource set corresponding to the reference signal resource instructions SSB-RI / CRI#1 and #3 for that group, and all the reference signals indicated by SSB-RI / CRI#1 and #3 belong to one reference signal resource set for prediction. If RSRP#2 and #4 are one group, another third instruction piece is used to indicate the third reference signal resource set corresponding to the reference signal resource instructions SSB-RI / CRI#2 and #4 for that group, and all the reference signals indicated by SSB-RI / CRI#2 and #4 belong to another reference signal resource set for prediction.

[0107] [Table 6] Furthermore, in Tables 3 and 5 above, when the first report includes both a predicted quantity and a measured quantity, the fifth instruction information can be used to indicate that the type of reference signal in the third reference signal resource set is SSB or CSI-RS. This avoids the inability to distinguish the corresponding reference signal resource sets when the reference signal resource indications for the predicted quantity and the measured quantity are the same. However, the embodiments of the present invention are not limited thereto. A sixth instruction information may be added to distinguish between predicted and measured quantities using a predefined method, or to indicate whether the type of reported quantity is a predicted quantity or a measured quantity, and to further distinguish the reference signal resource set to which the reference signal corresponding to the reference signal resource indication for the predicted and measured quantities belongs. Further explanations of other examples are omitted here.

[0108] Furthermore, in the above embodiments, the measured and / or predicted quantities included in the first report may be an optimal predetermined number of measured and / or predicted quantities obtained from the measured and / or predicted quantities, but the embodiments of the present invention are not limited thereto.

[0109] In the above embodiment, the relationship between the first reference signal resource set and the second reference signal resource set is established by additional signaling between the terminal device and the network device, but embodiments of the present invention are not limited thereto. The network device does not have to configure this second instruction information, and the terminal device may select one or more third reference signal resource sets from a plurality of reference signal resource sets configured by the network device according to the characteristics of the AI ​​model and / or function, and in the first report, add one or more third instruction pieces indicating the selected third reference signal resource set. Here, the reference signal resource instruction corresponds to the third reference signal resource set. The third reference signal resource set is one of the second reference signal resource sets and / or the first reference signal resource set from one or more second reference signal resource sets. That is, the third instruction piece is used to indicate the third reference signal resource set to which the reference signal corresponding to the reference signal resource instruction belongs.

[0110] For example, the AI ​​model has an input dimension of 16 and an output dimension of 64, meaning that the measured quantities of 16 reference signals (16 beams (pairs)) are input to the AI ​​model to obtain predicted quantities of 64 reference signals (64 beams (pairs)). In this case, the network device configures one reference signal resource set containing 16 reference signals for the terminal device in the reporting configuration information and instructs it to use the reference signal resource set for beam measurement. The terminal device may select one or more reference signal resource sets containing 64 reference signals from the multiple reference signal resource sets configured by the network device in the reference signal resource set configuration information as the reference signal resource set for prediction of the AI ​​model (third reference signal resource set). In this case, one or more third instruction pieces indicating one or more third reference signal resource sets are added to the first report, and embodiments of this third instruction piece may refer to those described above. Preferably, the terminal device may further transmit a fifth instruction in the first report indicating that the reference signal type in the third reference signal resource set is SSB or CSI-RS, but this will not be explained here.

[0111] The above embodiments illustrate examples of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, each of the above embodiments may be used individually, or one or more of the above embodiments may be used in combination.

[0112] According to this embodiment, the network device associates a reference signal resource set for measurement with a reference signal resource set for prediction using second instruction information, so that when the terminal device reports a reported quantity, it can accurately indicate the beam (pair) information corresponding to each reported quantity, i.e., the reference signal resource in the reference signal resource set for prediction, thus solving the above-mentioned problems of the prior art. Alternatively, the terminal device adds third instruction information to the reporting instance, instructing that the reference signal resource corresponding to the reported quantity indicates the corresponding reference signal resource set, thereby enabling the terminal device to accurately indicate the beam (pair) information corresponding to each reported quantity, i.e., the reference signal resource in the reference signal resource set for prediction, thus solving the above-mentioned problems of the prior art.
