Description

Information sending and receiving method and device, and communication system Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] As low-frequency spectrum resources become scarce, millimeter-wave (mmWave) bands offer greater bandwidth, making them a crucial frequency band for 5G NR (New Radio) systems. Due to their shorter wavelengths, mmWaves exhibit different propagation characteristics than traditional low-frequency bands, such as higher propagation loss and poor reflection and diffraction performance. Therefore, larger antenna arrays are typically employed to form shaped beams with greater gain, overcome propagation loss, and ensure system coverage. The 5G NR standard incorporates a series of beam management solutions, including beam scanning, beam measurement, beam reporting, and beam indication. However, a large number of transmit and receive beams significantly increases system load and latency.

[0003] With the development of artificial intelligence (AI) technology, applying it to the physical layer of wireless communications to address the difficulties of traditional methods has become a current technical trend. For beam management, using AI models to predict the optimal spatial beam pair based on a small number of beam measurements can significantly reduce system load and latency.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] In traditional beam measurement reporting, the network device configures a reference signal set for the terminal device's beam measurement and configures the measurement report accordingly. The report configuration includes information about the reference signal set, instructing the terminal device to measure the quality of the reference signals in the reference signal set and report it to the network device. The terminal device measures the reference signal quality according to the network device's configuration and reports the reported quantity to the network device. The reported quantity is the measurement quantity obtained from the measurement. The report content includes the measurement quantity and an indication of the reference signal resource corresponding to the measurement quantity.

[0007] If the AI ​​model is deployed on the terminal device side, and the network device is configured with a reference signal set for beam measurement, the terminal device can measure the reference signals in the reference signal set to obtain a measurement quantity, and use the measurement quantity as the input of the AI ​​model to obtain a predicted quantity. The reported quantity reported by the terminal device can be a measured quantity and / or a predicted quantity, but when the reported reported quantity is a predicted quantity, it is also necessary to report the reference signal resource indication corresponding to the predicted quantity. However, there may be a situation where the reference signal or beam (pair) corresponding to the predicted quantity is not included in the reference signal set used for beam measurement. Therefore, the reference signal resource indication cannot indicate the reference signal or beam (pair) corresponding to the predicted quantity.

[0008] To address at least one of the above problems, embodiments of the present application provide an information sending and receiving method, device, and communication system.

[0009] According to one aspect of an embodiment of the present application, there is provided an information transceiver device, applied to a terminal device, the device comprising:

[0010] A first sending unit, configured to send reference signal set configuration information and report configuration information to a terminal device, wherein the reference signal set includes a first reference signal set and / or a second reference signal set;

[0011] A first receiving unit is configured to receive a first report from the terminal device.

[0012] According to another aspect of an embodiment of the present application, there is provided an information transceiver device, applied to a network device, the device comprising:

[0013] a second receiving unit, configured to receive reference signal set configuration information and report configuration information sent by a network device, wherein the reference signal set includes the first reference signal set and / or the second reference signal set;

[0014] A second sending unit is configured to send a first report to the network device.

[0015] According to another aspect of an embodiment of the present application, a communication system is provided, including a terminal device and / or a network device, wherein the terminal device includes the information transceiver device described in the aforementioned first aspect, and the network device includes the information transceiver device described in the aforementioned other aspect.

[0016] One of the beneficial effects of the embodiments of the present application is that: through the above embodiments, the network device establishes an association between the measurement set of the reference signal and the prediction set of the reference signal through the second indication information, thereby enabling the terminal device to correctly indicate the beam (pair) information corresponding to each reporting amount when reporting the reporting amount, that is, the reference signal resources in the reference prediction set, thereby solving the above-mentioned problems in the prior art. Alternatively, the terminal device adds a third indication information in the reporting instance to indicate the reference signal set corresponding to the reference signal resource indication corresponding to the reporting amount, thereby enabling the terminal device to correctly indicate the beam (pair) information corresponding to each reporting amount when reporting the reporting amount, that is, the reference signal resources in the reference prediction set, thereby solving the above-mentioned problems in the prior art.

[0043] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0044] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0045] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0046] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0047] The terminal device 102 may send data to the network device 101, for example, using an authorized or unauthorized transmission mode. The network device 101 may receive data sent by one or more terminal devices 102 and provide feedback to the terminal device 102, such as ACK / NACK information. The terminal device 102 may confirm the end of the transmission process, or may continue with new data transmission, or may retransmit the data based on the feedback information.

[0048] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0049] An AI model (or ML model) includes, but is not limited to, an input layer (input), multiple convolutional layers, a concatenation layer (concat), a fully connected layer (FC), and a quantizer. The processing results of multiple convolutional layers are merged in the concatenation layer. The specific structure of the AI ​​model can be found in existing technologies and will not be detailed here.

[0050] In 5G and 6G systems, a wide range of terminal technical features (UE features) are defined. Not all features are required to be supported by terminal devices. The network obtains information about UE feature support by querying and reporting terminal device capabilities, also known as UE capabilities. This allows the network to understand UE capabilities and provides a basis for subsequent terminal scheduling, configuration, and communication.

[0051] To support diverse terminal functionality, existing standards predefine multiple features for terminals. Each feature further predefines one or more feature groups, and each feature group predefines one or more components. Features, feature groups, and components are each assigned an identifier or serial number. Based on current 5G-Advanced and 6G technology trends, when a terminal device may support multiple AI / ML functions or models, corresponding features or feature groups can be predefine for each AI / ML function or model.

[0052] When AI / ML models are applied to beam management, such as beam spatial prediction and beam temporal prediction, each can be predefined as a feature, such as an AI / ML feature for beam spatial prediction and an AI / ML feature for beam temporal prediction. Alternatively, support for AI / ML models for beam management can be predefined as a feature, and one or more feature groups can be predefined, such as an AI / ML feature group for beam spatial prediction and an AI / ML feature group for beam temporal prediction. This application does not limit how AI / ML functions or models are defined as features or feature groups.

[0053] In the function-based lifecycle management process, when a terminal supports multiple AI / ML functions, an AI / ML function can be defined by an AI / ML feature or an AI / ML feature group.

[0054] In the model-based lifecycle management process, when a terminal supports multiple AI / ML models, an AI / ML model can be defined by an AI / ML feature or an AI / ML feature group.

[0055] The above-mentioned AI / ML functions or models and related parameters can be specified through predefined features or feature groups for common understanding when the network side and the terminal side communicate capability information.

[0056] In the embodiments of the present application, a function or a model may also be referred to as a feature or a feature group, and different features or feature groups may include corresponding parameters or application conditions. Different features or feature groups may have an ID or a corresponding index or logical identifier.

[0057] In this way, when the terminal supports multiple AI / ML functions or models, the functions or models can be distinguished by function and / or model identifiers or logical identifiers, or by feature or feature group identifiers or serial numbers.

[0058] In the function-based lifecycle management process, to implement a certain function, the terminal device can be specifically implemented by one AI / ML model or multiple AI / ML models, or multiple functions can be implemented by one AI / ML model, and the specific implementation method does not need to be informed to the network device.

[0059] In the function-based lifecycle management process, when a function is implemented by multiple models, different models can correspond to different scenarios, different sites, different cells, different configurations, different application conditions, etc., which are determined by the model training and development process.

[0060] In the following embodiments, “reference signal”, “beam (pair)” and “reference signal resource” may be interchanged.

[0061] The inventors discovered that when the AI ​​model is deployed on the terminal device side to perform beam (pair) prediction, there are two reference signal sets, including: a measurement set of reference signals and a prediction set of reference signals, wherein the measurement set of reference signals refers to the set of reference signals used for beam measurement (that is, the set of reference signals corresponding to the measurement quantity input by the model), and the prediction set of reference signals refers to the set of reference signals corresponding to the beam prediction quantity (that is, the set of reference signals corresponding to the prediction quantity output by the model).

[0062] For example, there are at least the following two prediction scenarios: (1) The AI ​​model uses the measurement quantities of some beams (pairs) to output the prediction quantities of all beams (pairs). In this case, the reference signal measurement set is a subset of the prediction set. (2) When the AI ​​model uses the measurement quantities of wide beams (SSBs) to output the prediction quantities of thin beams, the reference signal measurement set is the SSB signal set, and the reference signal prediction set is the CSI-RS signal set. Therefore, the reference signal measurement set and the reference signal prediction set are not the same reference signal set.

[0063] When a terminal device reports a predicted quantity to a network device, the reference signal resource indication corresponding to the predicted quantity actually corresponds to the reference signal prediction set, not the reference signal measurement set. However, according to the definition of the existing standard, the reference signal resource indication is based on the reference signal measurement set. Because the reference signal measurement set and the prediction set are different sets, there may be cases where the reference signal, or beam (pair), corresponding to the predicted quantity is not included in the measurement set. Therefore, when reporting the predicted quantity, the reference signal or beam (pair) corresponding to the predicted quantity cannot be indicated.

[0064] In response to the above problems, embodiments of the present application provide a method and device for sending and receiving information, which are described below with reference to the accompanying drawings and embodiments.

[0065] Embodiments of the first aspect

[0066] An embodiment of the present application provides a method for sending and receiving information, which is described from the perspective of a network device.

[0067] FIG2 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0068] 201. A network device sends reference signal set configuration information and report configuration information to a terminal device, where the reference signal set includes a first reference signal set and / or a second reference signal set.

[0069] 202. The network device receives a first report from the terminal device.

[0070] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0071] In some embodiments, the network device can configure multiple reference signal (resource) sets for the terminal device, and the reference signal can be a reference signal such as CSI-RS and / or SSB. For example, the configured reference signal set is a reference signal list, and each reference signal set consists of one or more reference signals. In other words, the network device can send reference signal configuration information to the terminal device, and the reference signal configuration information includes an identifier of the reference signal set and an identifier of one or more reference signals constituting the reference signal set.

[0072] For example, when the reference signal is SSB, the reference signal configuration information can be carried by the SSB resource set configuration information element CSI-SSB-ResourceSet, including the reference signal set identifier csi-SSB-ResourceSetId; for example, when the reference signal is CSI-RS, the reference signal configuration information can be carried by the non-zero power CSI-RS resource set configuration information element NZP-CSI-RS-ResourceSet, including the reference signal set identifier nzp-CSI-ResourceSetId; or the reference signal configuration information can be carried by the information element CSI-ResourceConfig, including the configuration information of one or more reference signal sets. For the data format of each information element, please refer to the relevant technology, and no examples will be given here one by one. The embodiments of the present application are not limited to this.

[0073] In some embodiments, in addition to the reference signal configuration information, the network device may also send reporting configuration information to the terminal device. The reporting configuration information (for example, carried by the information element CSI-ReportConfig) may include a reporting configuration identifier, a reporting configuration type, including periodic, semi-periodic semiPersistentOnPUCCH / semiPersistentOnPUSCH, and aperiodic, a reporting quantity type (for example, L1-RSRP (L1Reference Signal Receiving Power) or L1-SINR (L1Signal to Interference plus Noise Ratio), and a reference signal set identifier, where the reference signal set identifier is one or more of the reference signal set identifiers in the reference signal configuration information.

[0074] The above reference signal configuration and reporting configuration may also include other information. For details, please refer to the relevant technology, and the embodiments of the present application are not limited to this.

[0075] In some embodiments, the reference signal set configured by the reference signal configuration information includes a first reference signal set and / or a second reference signal set. The first reference signal set can be used for beam measurement, and the second reference signal set can be used for beam prediction, that is, the first reference signal set is a measurement set of reference signals, and the second reference signal set is a prediction set of reference signals; or the second reference signal set can be used for beam measurement, and the first reference signal set can be used for beam prediction, that is, the second reference signal set is a measurement set of reference signals, and the first reference signal set is a prediction set of reference signals, but the embodiments of the present application are not limited to this. The first reference signal set and the second reference signal set can also be used for other beam management functions, which are not exemplified one by one here. The first reference signal set and the second reference signal set can be CSI-RS reference signal sets and / or SSB reference signal sets.

[0076] In some embodiments, in order to conveniently distinguish the uses of the aforementioned reference signal set, the network device may further send a first indication message to the terminal device, wherein the first indication message indicates that the first reference signal set is at least used for beam measurement, or for beam prediction. The first indication message may be carried by a radio resource control signaling (RRC), a medium access control (MAC) control element (CE) or a downlink control information (DCI), and the aforementioned RRC or MAC CE or DCI may be existing or newly added. For example, the first indication message may be carried by the aforementioned reference signal configuration information element or a reporting configuration information element. The embodiments of the present application are not limited to this.

[0077] For example, the first indication information may be a newly added 1-bit information in the reference signal configuration information element. When the bit value of the 1-bit is 1, it indicates that the first reference signal set configured in the reference signal configuration information element is a measurement set of reference signals, which is used for beam measurement. When the bit value is 0, it indicates that the first reference signal set configured in the reference signal configuration information element is a prediction set of reference signals, which is used for beam prediction, and vice versa.

[0078] For example, the first indication information may be a 1-bit information newly added in the reporting configuration information element. When the bit value of the 1-bit is 1, it indicates that the first reference signal set configured in the reporting configuration information element is a measurement set of reference signals, which is used for beam measurement. When the bit value is 0, it indicates that the first reference signal set configured in the reference signal configuration information element is a prediction set of reference signals, which is used for beam prediction, and vice versa.

[0079] The above is only an example. New signaling can also be designed to carry the first indication information, which will not be given one by one here.

[0080] In some embodiments, the relationship between the first reference signal set and the second reference signal set can be configured between the terminal device and the network device through additional signaling. More specifically, the network device configures association information for the two reference signal sets required by the terminal device AI model, which is described in detail below.

[0081] In some embodiments, a network device sends second indication information to a terminal device, where the second indication information indicates one or more second reference signal sets, and the one or more second reference signal sets are associated with the first reference signal set, wherein the association of the one or more second reference signal sets with the first reference signal set indicates that the one or more second reference signal sets are related to (or correspond to, or match, or pair with) the first reference signal set. That is, the second indication information can indicate, for a measurement set of a reference signal, one or more associated prediction sets of reference signals, or the second indication information can indicate, for a prediction set of a reference signal, one or more associated measurement sets of reference signals, thereby establishing a correspondence (an association relationship, a matching relationship, or a pairing relationship) between the measurement set of the reference signal and the prediction set of the reference signal. For example, the measurement set of the reference signal and the prediction set of the reference signal correspond to the input and output of the AI ​​model on the terminal device side, respectively. The measurement set of the reference signal and the prediction set of the reference signal (the first reference signal set and the second reference signal set) are associated, which can indicate that the measurement set of the reference signal and the prediction set of the reference signal correspond to the input and output of an AI model. It can also be said that when the measurement set of the reference signal and the prediction set of the reference signal correspond to the input and output of an AI model, the measurement set of the reference signal and the prediction set of the reference signal are related (associated or corresponding or matched or paired).

[0082] In some embodiments, different first reference signal sets may be associated with the same second reference signal set (same number and identifiers), or with different second reference signal sets (different numbers and / or identifiers). This embodiment of the present application is not limited to this. The following describes how to determine which reference signal sets (fourth reference signal sets) can be (or are capable of) being associated with the first reference signal set.

[0083] In some embodiments, the one or more (N) fourth reference signal sets associated with the first reference signal set are obtained at least through the characteristics / feature groups of the terminal device or the capability report of the terminal device. The one or more (M) second reference signal sets are part (M is less than N) or all (M is equal to N) reference signal sets in the one or more (N) fourth reference signal sets, and M and N are integers greater than or equal to 1. That is, the first reference signal set obtained through the characteristics / feature groups of the terminal device or the capability report of the terminal device can (can) be associated with the N fourth reference signal sets, and when the second indication information is used to indicate the second reference signal set, M fourth reference signal sets can be selected or configured from the N fourth reference signal sets as the M second reference signal sets associated with the first reference signal set according to its implementation algorithm.

[0084] In some embodiments, when the parameters of one or more AI models and / or functions are defined through the features / feature groups of the terminal device or in the capability report of the terminal, the network device obtains the corresponding model parameters (such as the dimensions of the input and output of the AI ​​model, the pattern of the measurement set, etc.), and determines whether different reference signal sets can be correlated, or whether they can be used as input and output of the AI ​​model based on the model parameters.

[0085] For example, there are two AI models on the terminal device side, one of which has an input dimension of 16 and an output dimension of 64, and the other has an input dimension of 16 and an output dimension of 128. Then, for the reference signal set (measurement set, first reference signal set) with a dimension of 16, the reference signal set (fourth reference signal set) that can be associated through the characteristics / feature groups of the terminal device or the capability report of the terminal device is a reference signal set (prediction set) with dimensions of 64 and 128. The network device can select or configure reference signal sets with dimensions of 64 and 128 (all fourth reference signal sets) as two second reference signal sets associated with the first reference signal set, or it can select or configure a reference signal set with a dimension of 64 from the two fourth reference signal sets as a second reference signal set associated with the first reference signal set according to its implementation algorithm (for example, when the network device expects the AI ​​model for beam prediction of the terminal device to obtain better prediction accuracy).

[0086] For example, there are two AI models on the terminal device side, one of which has an input dimension of 16 and an output dimension of 64, and the other AI model has an input dimension of 32 and an output dimension of 64. Then, for the reference signal set (prediction set, first reference signal set) with a dimension of 64, the reference signal set (fourth reference signal set) that can be associated through the characteristics / feature groups of the terminal device or the capability report of the terminal device is a reference signal set (measurement set) with dimensions of 16 and 32. The network device can select or configure reference signal sets with dimensions of 16 and 32 (all fourth reference signal sets) as two second reference signal sets associated with the first reference signal set, or it can select or configure a reference signal set with a dimension of 16 from the two fourth reference signal sets as a second reference signal set associated with the first reference signal set according to its implementation algorithm (for example, when the terminal device expects the terminal device beam prediction model to reduce the reference signal load more).

[0087] In some embodiments, the second indication information may be carried by radio resource control signaling (RRC), a medium access control (MAC) control element (CE), or downlink control information (DCI). The aforementioned RRC or MAC CE or DCI may be existing or newly added, and the embodiments of the present application are not limited thereto. For example, the second indication information may be carried by the aforementioned reference signal configuration information element or reporting configuration information element. The following examples illustrate this.

[0088] For example, the network device may add the second indication information in the reference signal configuration information element to establish an association between the first reference signal set and the second reference signal set; in the information element CSI-SSB-ResourceSet, the identifier of the existing reference signal set csi-SSB-ResourceSetId may be regarded as the identifier of the first reference signal set, and the second indication information may be added to the information element CSI-SSB-ResourceSet to associate one or more second reference signal sets, which may be a CSI-RS reference signal set; or, in the information element NZP-CSI-RS-ResourceSet, the identifier of the existing reference signal set nzp-CSI-ResourceSetId may be regarded as the identifier of the first reference signal set. An identifier of a reference signal set, in NZP-CSI-RS-ResourceSet, a second indication information is added to associate one or more second reference signal sets, which can be an SSB reference signal set or a CSI-RS reference signal set; or, in the information element CSI-ResourceConfig, the reference signal set list csi-RS-ResourceSetList can be regarded as one or more first reference signal sets, and in CSI-ResourceConfig, one or more second indication information is added to indicate one or more associated second reference signal sets for each first reference signal set, which can be an SSB reference signal set or a CSI-RS reference signal set. In the above example, when multiple first reference signal sets are configured, a second indication information can be added for the configuration of each first reference signal set, indicating that each first reference signal set is associated with one or more second reference signal sets.

[0089] For example, the network device can add the second indication information in the reporting configuration information element to establish an association between the first reference signal set and the second reference signal set; in the reporting configuration information element, the identifier of the existing reference signal set can be regarded as the identifier of the first reference signal set, and the second indication information is added to associate one or more second reference signal sets, and the second reference signal set can be an SSB reference signal set or a CSI-RS reference signal set.

[0090] The above is only an example. New signaling can also be designed to carry the second indication information, which will not be given one by one here.

[0091] In some embodiments, the second indication information is at least an identifier of a reference signal set, or a bit map, as illustrated in the following examples.

[0092] For example, the second indication information is represented by an identifier of a reference signal set, which is the identifier of the reference signal set in the reference signal configuration information element, such as NZP-CSI-RS-RourceSetId or CSI-SSB-ResourceSetId. The second indication information may contain identifiers of one or more second reference signal sets. For example, the second indication information is represented by a bitmap, and the length of the bitmap is related to the maximum number of configured reference signal sets. For example, the length (number of bits) of the bitmap is equal to the maximum number of configured reference signal sets, and each bit corresponds to a reference signal set (for example, the position or serial number of the bit in the bitmap corresponds to the identifier of the reference signal set). A bit value of the bitmap is used to indicate whether the corresponding reference signal set is the second reference signal set or not, or in other words, each bit value is used to indicate whether the corresponding reference signal set is the second reference signal set associated with the first reference signal set. For example, when the bit value is a first specific value, it indicates that the corresponding reference signal set is an associated second reference signal set. When the bit value is a second specific value, it indicates that the corresponding reference signal set is not an associated second reference signal set. As for which bits are set to the first specific value, it can be determined based on the identifier of the second reference signal set. For example, if the identifier of the second reference signal set is 1, 3, or 5, then the bit values ​​corresponding to the bits at the 2nd, 4th, and 6th positions in the bitmap are the first specific values. For example, the first specific value is 1 and the second specific value is 0, or the first specific value is 0 and the second specific value is 1. The embodiments of the present application are not limited to this. When there is more than one first specific value in the bitmap, it indicates that the first reference signal set is associated with multiple second reference signal sets. When there is one first specific value in the bitmap, it indicates that the first reference signal set is associated with one second reference signal set.

[0093] In some embodiments, when the first reference signal set is an SSB reference signal set, one or more associated second reference signal sets are CSI-RS reference signal sets. That is, the first reference signal set and the second reference signal set are reference signal sets of different types. When the first reference signal set is a CSI-RS reference signal set, one or more associated second reference signal sets may be SSB reference signal sets. That is, the first reference signal set and the second reference signal set are reference signal sets of different types. Alternatively, when the first reference signal set is a CSI-RS reference signal set, one or more associated second reference signal sets may be CSI-RS reference signal sets, and the first reference signal set and the second reference signal set are reference signal sets of the same type. As described above, the first reference signal set and the second reference signal set correspond to different sets. When the first reference signal set and the second reference signal set are of the same type, their reference signal set identifiers are different and can be distinguished by the reference signal set identifiers. However, when the first reference signal set and the second reference signal set are of different types, their reference signal set identifiers may be the same. In other words, when the network device is configured with two types of reference signal sets, if the second reference signal set is indicated based on the identifier of the reference signal set, it is impossible to determine which type of reference signal set the identifier corresponds to. Therefore, in an embodiment of the present application, the network device may also send or not send fourth indication information to the terminal device, and the fourth indication information is used to indicate that the type of reference signal in the second reference signal set is the same as or different from the type of reference signal in the first reference signal set, and the reference signal type is CSI-RS or SSB; or, the fourth indication information is used to indicate that the type of reference signal in the second reference signal set is SSB or CSI-RS. The fourth indication information can be carried by radio resource control signaling (RRC), medium access control (MAC) control element (CE) or downlink control information (DCI). The above-mentioned RRC or MAC CE or DCI can be existing or newly added. For example, the fourth indication information can be carried by the same information element as the second indication information, or by different information elements. The embodiment of the present application is not limited to this.

[0094] In some embodiments, when the network device does not send the fourth indication information, it indicates that the type of the reference signal in the second reference signal set is the same as the type of the reference signal in the first reference signal set; when the network device sends the fourth indication information, it indicates that the type of the reference signal in the second reference signal set is different from the type of the reference signal in the first reference signal set, thereby indicating the type of the reference signal in the second reference signal set, and vice versa.

[0095] In some embodiments, the network device sends fourth indication information, which is represented by 1 bit. When the bit value of the 1 bit is 1, it indicates that the type of the reference signal in the second reference signal set is SSB; when the bit value of the 1 bit is 0, it indicates that the type of the reference signal in the second reference signal set is CSI-RS, and vice versa.

[0096] For example, the network device configures N1 SSB reference signal sets for the terminal device, and the CSI-SSB-ResourceSetIds are 0 to N1-1 respectively. In addition, the network device configures N2 NZPs for the terminal device. The reference signal set of the CSI-RS, NZP-CSI-RS-RourceSetId is 0 to N2-1 respectively; the reference signal configuration of the CSI-RS reference signal set with ID 0 also includes second indication information and fourth indication information, the second indication information is {1, 3, 5}, and the bit value of the fourth indication information is 0, which indicates that the CSI-RS reference signal set with ID 0 (first reference signal set) is associated with the SSB reference signal set with IDs 1, 3, and 5 (second reference signal set); or the reference signal configuration of the CSI-RS reference signal set with ID 0 (first reference signal set) also includes second indication information, the second indication information is {1, 3, 5}, since the fourth indication information is not included, it indicates that the second reference signal set is of the same type as the first reference signal set, that is, the CSI-RS reference signal set with ID 0 (first reference signal set) is associated with the CSI-RS reference signal set with IDs 1, 3, and 5 (second reference signal set). Examples are not given one by one here.

[0097] Alternatively, the reference signal configuration for the CSI-RS reference signal set (first reference signal set) with ID 0 also includes second indication information, where the second indication information is {1, 3, 5}, and the bit value of the fourth indication information is 0, indicating that the CSI-RS reference signal set (first reference signal set) with ID 0 is associated with the CSI-RS reference signal set (second reference signal set) with IDs 1, 3, and 5. The bit value of the fourth indication information is 1, indicating that the CSI-RS reference signal set (first reference signal set) with ID 0 is associated with the SSB reference signal set (second reference signal set) with IDs 1, 3, and 5. Examples are not given one by one here.

[0098] For example, the reporting configuration information for the CSI-RS reference signal set with ID 0 includes second indication information and fourth indication information, where the second indication information is a bitmap {0000 0000 0010 1010} and the bit value of the fourth indication information is 0, indicating that the CSI-RS reference signal set with ID 0 (first reference signal set) is associated with the SSB reference signal sets with IDs 1, 3, and 5 (second reference signal sets). Examples are not given here one by one. Alternatively, the reporting configuration information for the CSI-RS reference signal set with ID 0 (first reference signal set) also includes second indication information, where the second indication information is a bitmap {0000 0000 0010 1010}. Since the fourth indication information is not included, it indicates that the second reference signal set is of the same type as the first reference signal set, that is, the CSI-RS reference signal set with ID 0 (first reference signal set) is associated with the CSI-RS reference signal sets with IDs 1, 3, and 5 (second reference signal sets). Examples are not given here one by one.

[0099] Alternatively, the reporting configuration information for the CSI-RS reference signal set (first reference signal set) with ID 0 also includes second indication information, where the second indication information is {0000 0000 0010 1010}, and the bit value of the fourth indication information is 0, indicating that the CSI-RS reference signal set (first reference signal set) with ID 0 is associated with the CSI-RS reference signal sets (second reference signal set) with IDs 1, 3, and 5. The bit value of the fourth indication information is 1, indicating that the CSI-RS reference signal set (first reference signal set) with ID 0 is associated with the SSB reference signal sets (second reference signal set) with IDs 1, 3, and 5. Examples are not given one by one here.

[0100] For example, for scenario (1), the AI ​​model uses the measurement quantities of some beams (pairs) to output the predicted quantities of all beams (pairs). The NZP-CSI-RS-RourceSet in the reporting configuration information element can be used as the first reference signal set, and second indication information can be added to indicate the predicted set of one or more reference signals associated with the first reference signal set (second reference signal set). The second indication information can be one or more NZP-CSI-RS-RourceSetId configured in the reference signal configuration information element (and can also include fourth indication information).

[0101] For example, for scenario (1), the AI ​​model uses the measurement quantities of some beams (pairs) to output the predicted quantities of all beams (pairs). In the reference signal configuration of each NZP-CSI-RS-RourceSet (first reference signal set) in the reference signal configuration information element, second indication information can be added to indicate a second reference signal set associated with the first reference signal set, and the second indication information indicates one or more NZP-CSI-RS-RourceSetIds (and may also include fourth indication information). In addition, first indication information can also be added to the reference signal configuration information element to indicate that the first reference signal set is used for beam measurement or beam prediction.

[0102] For example, for scenario (2), the AI ​​model uses the measurement amount of a wide beam (SSB) to output the predicted amount of a fine beam. The CSI-SSB-ResourceSet in the reporting configuration information element can be used as the first reference signal set, and second indication information can be added to indicate a second reference signal set associated with the first reference signal set. The second indication information indicates one or more NZP-CSI-RS-RourceSetIds (and may also include fourth indication information).

[0103] For example, for scenario (2), the AI ​​model uses the measurement amount of a wide beam (SSB) to output the predicted amount of a fine beam. A second indication information can be added to the reference signal configuration of each CSI-SSB-ResourceSet (first reference signal set) in the reference signal configuration information element to indicate the second reference signal set associated with the first reference signal set. The second indication information indicates one or more NZP-CSI-RS-RourceSetIds (and may also include fourth indication information).

[0104] In some embodiments, after receiving the aforementioned reference signal configuration and reporting configuration, the terminal device performs beam measurement and uses an AI model to perform beam prediction, that is, measures the signal of the reference signal measurement set to obtain a measurement amount, inputs the measurement amount into the AI ​​model deployed on the terminal device side, and obtains a predicted amount. The measurement amount and the predicted amount can be L1-RSRP or L1-SINR. The terminal device can generate a first report based on at least the first indication information and / or the second indication information and / or the fourth indication information, and send the first report to the network device. The first report is a reporting instance. The first report includes one or more reporting amounts or one or more reporting amounts and a reference signal resource indication corresponding to the reporting amount. The reporting amount is obtained based on measurement and / or prediction, that is, the reporting amount is a measurement amount and / or a predicted amount. The reference signal resource indication includes a synchronization signal block resource indicator (SSB resource indicator, SSB RI) or a channel state information reference signal resource indicator (CSI-RS resource indicator, CRI). The reference signal resource indication corresponds to the second reference signal set and / or the first reference signal set. In other words, the reference signal resource indicates that the reference signal corresponding to the reference signal set belongs to the second reference signal set and / or the first reference signal set.

[0105] In some embodiments, the first report may or may not include one or more third indication information and / or fifth indication information. The third indication information is used to indicate a third reference signal set, wherein the reference signal resource indication corresponds to the third reference signal set. The third reference signal set is a second reference signal set and / or the first reference signal set among the one or more second reference signal sets. That is, the third indication information is used to indicate the third reference signal set to which the reference signal corresponding to the reference signal resource indication belongs. The fifth indication information is used to indicate whether the reference signal in the third reference signal set is an SSB or CSI-RS type. The third indication information is at least a reference signal set identifier or a bitmap. The specific implementation may refer to the second indication information, except that only one bit in the bitmap is set to the first specific value. The implementation of the fifth indication information may refer to the fourth indication information. The third indication information and / or the fifth indication information may be carried by uplink control information (UCI), and the fifth indication information has a one-to-one correspondence with the third indication information. The following examples are illustrative using the example of configuring the first reference signal set as the reference signal measurement set in the report configuration information and the second reference signal set associated with the first reference signal set as the reference signal prediction set.

[0106] In some embodiments, when a first reference signal set is associated with a second reference signal set, the first report may not include the third indication information, i.e., the reference signal resource indicator in the first report can be used to determine which reference signal set the indicated reference signal belongs to. For example, when the first report includes only a measurement quantity, the reference signal resource indicator corresponding to the measurement quantity corresponds to the first reference signal set, i.e., the reference signal corresponding to the reference signal resource indicator corresponding to the measurement quantity belongs to the measurement set of reference signals (the first reference signal set); for example, when the first report includes only a forecast quantity, since the first reference signal set is associated with a second reference signal set, the second reference signal set is also known and uniquely determined based on the second indication information and / or the fourth indication information. The reference signal resource indication corresponding to the predicted amount corresponds to the second reference signal set, that is, the reference signal corresponding to the reference signal resource indication corresponding to the predicted amount belongs to the predicted set of reference signals (an associated second reference signal set), and no additional third indication information is required to indicate the reference signal set to which the reference signal corresponding to the predicted amount belongs; when the first report includes both the measurement amount and the predicted amount, the first report may include the third indication information. When the first report includes both the measurement amount and the predicted amount, the third reference signal set indicated by the third indication information corresponding to the reference signal resource indication corresponding to the measurement amount is the first reference signal set, the reference signal corresponding to the reference signal resource indication corresponding to the measurement amount belongs to the measurement set of reference signals (the first reference signal set), and the third reference signal set indicated by the third indication information corresponding to the reference signal resource indication corresponding to the predicted amount is a second reference signal set, that is, the reference signal corresponding to the reference signal resource indication corresponding to the predicted amount belongs to the predicted set of reference signals (an associated second reference signal set). Optionally, the first report may also include fifth indication information, indicating that the type of the reference signal in the third reference signal set is SSB or CSI-RS. In this way, it is possible to avoid the situation where the reference signal resource indications corresponding to the predicted quantity and the measured quantity are the same and the corresponding reference signal sets cannot be distinguished.

[0107] In some embodiments, when one first reference signal set is associated with multiple second reference signal sets, the first report may further include or exclude one or more third indication information and / or fifth indication information.

[0108] For example, when the first report only includes the measurement amount, the reference signal resource indication corresponding to the measurement amount corresponds to the first reference signal set, that is, the reference signal corresponding to the reference signal resource indication corresponding to the measurement amount belongs to the measurement set of reference signals (the first reference signal set), and there is no need to include the third indication information in the first report; when the first report only includes the predicted amount, since the first reference signal set is associated with multiple second reference signal sets, the third indication information is required to further indicate to which predicted set of reference signals (the third reference signal set, or which second reference signal set among the multiple second reference signal sets) the reference signal corresponding to the reference signal resource indication corresponding to the predicted amount belongs; when the first report includes both the measurement amount and When the measurement is predicted, the third reference signal set indicated by the third indication information corresponding to the reference signal resource indication corresponding to the measurement amount is the first reference signal set, the reference signal corresponding to the reference signal resource indication corresponding to the measurement amount belongs to the measurement set of reference signals (the first reference signal set), and the third reference signal set indicated by the third indication information corresponding to the reference signal resource indication corresponding to the prediction amount is a second reference signal set, that is, the reference signal corresponding to the reference signal resource indication corresponding to the prediction amount belongs to the prediction set of reference signals (an associated second reference signal set). Optionally, the first report may further include fifth indication information indicating that the type of the reference signal in the third reference signal set is SSB or CSI-RS. In this way, it is possible to avoid the situation where the reference signal resource indications corresponding to the prediction amount and the measurement amount are the same and the corresponding reference signal sets cannot be distinguished.

[0109] In some embodiments, the first report includes the third indication information, and all reference signal resource indications in the first report correspond to the third reference signal set indicated by the third indication information.

[0110] For example, when the first report includes only one prediction quantity, the one prediction quantity corresponds to a prediction set of a reference signal, and a third indication information is used to indicate the prediction set (third reference signal set) of reference signals to which the reference signal corresponding to the reference signal resource indication corresponding to the one prediction quantity belongs.

[0111] For example, when the first report only includes multiple prediction quantities, the multiple prediction quantities may correspond to a prediction set of a reference signal. For example, in the inference process of the AI ​​model, the prediction quantity output by the AI ​​model corresponds to a beam (pair) corresponding to a prediction set of a reference signal. Therefore, a third indication information may be used to uniformly indicate the reference signal prediction set (third reference signal set) to which the reference signal corresponding to the reference signal resource indication corresponding to all prediction quantities belongs. As shown in Table 1 below, the first report includes 4 beams (pairs), namely 4 SSB-RI / CRI, each beam (pair) corresponds to 1 reporting amount, the reporting amount corresponding to SSB-RI / CRI#1 is L1-RSRP#1, the reporting amount corresponding to SSB-RI / CRI#2 is L1-RSRP#2, the reporting amount corresponding to SSB-RI / CRI#3 is L1-RSRP#3, and the reporting amount corresponding to SSB-RI / CRI#4 is L1-RSRP#4. When the 4 reporting amounts are all predicted amounts and the 4 predicted amounts correspond to a predicted set of reference signals, Table 1 includes a third indication information, which indicates a second reference signal set (predicted set of reference signals), and the reference signals corresponding to the 4 SSB-RI / CRIs belong to the second reference signal set.

[0112] Table 1

[0113] In some embodiments, the first report includes multiple (Y) third indication information, wherein one third indication information is used to indicate one third reference signal set; and the one or more (Z) reference signal resource indications in the first report correspond to the third reference signal set indicated by the one third indication information.

[0114] For example, when the first report includes a prediction quantity and one or more measurement quantities, the one prediction quantity corresponds to a prediction set of a reference signal, and a third indication information is used to indicate the prediction set of reference signals to which the reference signal corresponding to the reference signal resource indication corresponding to the one prediction quantity belongs (the third reference signal set is a second reference signal set), and another third indication information is used to indicate the measurement set of reference signals to which the reference signal indicated by the reference signal resource indication information corresponding to the one or more measurement quantities belongs (the third reference signal set is the first reference signal set). Optionally, fifth indication information can also be used to indicate whether the type of the reference signal in the third reference signal set is SSB or CSI-RS.

[0115] For example, when only multiple prediction quantities are included in the first report, the multiple (X) prediction quantities can correspond to multiple (Y) reference signal prediction sets, where X is greater than or equal to Y. For example, in the monitoring process of the AI ​​model, when the terminal device supports multiple beam prediction models and / or functions, different AI models and / or functions use the measurement quantities of the reference signals in the same reference signal measurement set to obtain the prediction quantities of the beams (pairs) corresponding to the prediction sets of the same or different dimensions. The first report includes the prediction quantities of multiple functions and / or models. Therefore, multiple (Y) third indication information is required for each model and / or function to indicate the reference signal resource corresponding to its respective prediction quantity and the reference signal prediction set (third reference signal set) to which the reference signal corresponding to the reference signal resource indication belongs.

[0116] As shown in Table 2 below, a third indication information indicates the reference signal prediction set (third reference signal set) to which the reference signal corresponding to the reference signal resource indication corresponding to a prediction amount belongs. The first report includes 4 beams (pairs), namely 4 SSB-RI / CRIs, and each beam (pair) corresponds to 1 reporting amount. The reporting amount corresponding to SSB-RI / CRI#1 is L1-RSRP#1, the reporting amount corresponding to SSB-RI / CRI#2 is L1-RSRP#2, the reporting amount corresponding to SSB-RI / CRI#3 is L1-RSRP#3, and the reporting amount corresponding to SSB-RI / CRI#4 is L1-RSRP#4. All 4 reporting amounts are prediction amounts, and the reference signals corresponding to the reference signal resource indications corresponding to the 4 prediction amounts belong to the same or different reference signal prediction sets. Table 2 includes 4 third indication information, and each third indication information indicates a third reference signal set (prediction set of reference signals), which corresponds to the prediction amount of a function and / or model respectively.

[0117] Table 2 (only includes forecast quantities)

[0118] For example, when the first report includes one or more measurement quantities and multiple prediction quantities, the one or more measurement quantities correspond to one reference signal measurement set, and the multiple (X) prediction quantities may correspond to multiple (Y) reference signal prediction sets, where X is greater than or equal to Y. Therefore, multiple (Y) third indication information is required to indicate, for each model and / or function, the reference signal prediction set to which the reference signal corresponding to the reference signal resource indication corresponding to its respective prediction quantity belongs (the third reference signal set is a second reference signal set), and one or more third indication information is required to indicate the reference signal measurement set to which the reference signal corresponding to the reference signal resource indication corresponding to the one or more measurement quantities belongs (the third reference signal set is the first reference signal set). Optionally, fifth indication information may also be used to indicate whether the type of the reference signal in the third reference signal set is SSB or CSI-RS.

[0119] As shown in Table 3 below, L1-RSRP#1 and #2 are measurement quantities, L1-RSRP#3 and #4 are prediction quantities, and Table 2 includes four third indication information, which indicates a third reference signal set (prediction set of reference signals), wherein the reference signals corresponding to SSB-RI / CRI#3 and 4 belong to the reference signals in the same or different third reference signal sets (a second reference signal set) indicated by the respective corresponding third indication information, and the reference signals corresponding to SSB-RI / CRI#1 and 2 belong to the reference signals in the same third reference signal set (first reference signal set) indicated by the respective corresponding third indication information. The difference from Table 2 is that, optionally, the first report may also include fifth indication information corresponding one-to-one to the third indication information, for indicating that the type of the reference signal in the third reference signal set is SSB or CSI-RS.

[0120] Table 3 (including measured and predicted quantities)

[0121] For example, a third indication information indicates the third reference signal set to which the reference signal resource indication corresponding to the multiple (Z) measurement quantities or predicted quantities belongs. As shown in Table 4 below, the first report includes 4 beams (pairs), that is, 4 SSB-RI / CRIs. Each beam (pair) corresponds to 1 reporting quantity, SSB-RI / CRI#1 corresponds to a reporting quantity of L1-RSRP#1, SSB-RI / CRI#2 corresponds to a reporting quantity of L1-RSRP#2, SSB-RI / CRI#3 corresponds to a reporting quantity of L1-RSRP#3, and SSB-RI / CRI#4 corresponds to a reporting quantity of L1-RSRP#4. All four reporting quantities are predicted quantities. And when the four prediction quantities correspond to two different reference signal prediction sets, Table 4 includes two third indication information, each of which indicates a third reference signal set (a prediction set of reference signals, a second reference signal set), corresponding to two reference signal resource indications, that is, SSB-RI / CRI#1 and #2 correspond to the same reference signal prediction set, or the reference signals indicated by SSB-RI / CRI#1 and #2 belong to one reference signal prediction set, SSB-RI / CRI#3 and #4 correspond to the same reference signal prediction set, or the reference signals indicated by SSB-RI / CRI#3 and #4 belong to another reference signal prediction set.

[0122] Table 4

[0123] Alternatively, as shown in Table 5 below, the difference from Table 4 is that L1-RSRP#1 and #2 are measurement quantities, L1-RSRP#3 and #4 are prediction quantities, and Table 5 includes two third indication information, each of which indicates a third reference signal set. The third reference signal set indicated by the third indication information corresponding to SSB-RI / CRI#1 and #2 is the first reference signal set, and SSB-RI / CRI#1 and #2 correspond to the same reference signal measurement set, or the reference signals indicated by SSB-RI / CRI#1 and #2 belong to a reference signal measurement set, and the third reference signal set indicated by the third indication information corresponding to SSB-RI / CRI#3 and #4 is a second reference signal set. SSB-RI / CRI#3 and #4 correspond to the same reference signal prediction set, or the reference signals indicated by SSB-RI / CRI#3 and #4 belong to a reference signal prediction set. The difference from Table 4 is that, optionally, the first report may also include fifth indication information corresponding one-to-one to the third indication information, which is used to indicate that the type of the reference signal in the third reference signal set is SSB or CSI-RS.

[0124] Table 5

[0125] For example, a third indication information indicates the third reference signal set to which the reference signal resource indication corresponding to multiple (Z) predicted quantities belongs. In this example, the first report also includes a group identifier corresponding to each reported quantity, that is, the report can be made in the form of a group. For example, as shown in Table 6 below, the first report includes 4 beams (pairs), that is, 4 SSB-RI / CRIs, and each beam (pair) corresponds to 1 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. The 4 reported quantities are all predicted quantities, and the 4 predicted quantities correspond to 2 different reference signals. The prediction set of the number, Table 6 includes 2 third indication information, each of the third indication information indicates a third reference signal set (prediction set of reference signals), which corresponds to a group of reference signal resource indications corresponding to the prediction quantity, that is, L1-RSRP#1 and #3 are a group, and a third indication information is used to indicate the reference signal resource indication corresponding to the group, SSB-RI / CRI#1 and #3 corresponding to the third reference signal set, and the reference signals indicated by SSB-RI / CRI#1 and #3 all belong to the prediction set of one reference signal. L1-RSRP#2 and #4 are a group, and another third indication information is used to indicate the reference signal resource indication corresponding to the group, SSB-RI / CRI#2 and #4 corresponding to the third reference signal set, and the reference signals indicated by SSB-RI / CRI#2 and #4 all belong to the prediction set of another reference signal.

[0126] Table 6

[0127] It should be noted that in Tables 3 and 5 above, when the first report includes both the predicted amount and the measured amount, the fifth indication information is used to indicate whether the type of the reference signal in the third reference signal set is SSB or CSI-RS. This can avoid the situation where the reference signal resource indications corresponding to the predicted amount and the measured amount are the same and the corresponding reference signal sets cannot be distinguished. However, the embodiments of the present application are not limited to this, and a predefined method can be used to distinguish the predicted amount and the measured amount, or a sixth indication information can be added to indicate whether the type of the reported amount is the predicted amount or the measured amount, thereby distinguishing the reference signal sets to which the reference signals corresponding to the reference signal resource indications corresponding to the predicted amount and the measured amount belong. Examples are not given one by one here.

[0128] In addition, the measured quantities and / or predicted quantities included in the first report in the above embodiment may be an optimal predetermined number of measured quantities and / or predicted quantities obtained based on measurement and / or prediction, but the embodiment of the present application is not limited thereto.

[0129] In the above embodiment, the relationship between the first reference signal set and the second reference signal set is configured between the terminal device and the network device through additional signaling, but the embodiment of the present application is not limited to this. The network device may also not configure the second indication information. The terminal device may select one or more third reference signal sets from the multiple reference signal sets configured by the network device according to the characteristics of the AI ​​model and / or function, and add one or more third indication information in the first report to indicate the selected third reference signal set, wherein the reference signal resource indication corresponds to the third reference signal set. The third reference signal set is a second reference signal set and / or the first reference signal set in the one or more second reference signal sets. That is, the third indication information is used to indicate the third reference signal set to which the reference signal corresponding to the reference signal resource indication belongs.
