Description

Information sending and receiving method and device 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] Assume a communication system has M beams on the transmitter side and N beams on the receiver side. Existing standards require measuring M*N beams. When M and N are large, measuring M*N beams results in significant system load and latency. Using models (e.g., AI models) to predict the optimal beam pair based on a small number of beam measurements can significantly reduce the system load and latency caused by beam measurements.

[0007] The inventors discovered that if the AI ​​model is deployed on the terminal device side, during the training phase of the AI ​​model, the network device configures a reference signal set for beam measurement, and sends the reference signals in the reference signal set to the terminal device through different transmission beams for beam measurement, and uses the measurement results as label data for AI model training. During the inference phase using the trained AI model, the AI ​​model only needs the measurement results of some transmission beams, that is, the terminal device only needs to receive some reference signals in the reference signal set. However, since the AI ​​model is deployed on the terminal device side, the terminal device knows the information of the reference signal required by the AI ​​model, but the network device does not know the information of the reference signal. Currently, there is no solution for the terminal device to inform the network device about the information of the reference signal.

[0008] The inventors discovered that if the AI ​​model is deployed on the network device side, during the training stage of the AI ​​model, the network device configures a reference signal set for beam measurement, and sends the reference signals in the reference signal set to the terminal device through different transmission beams for beam measurement. The terminal device reports the measurement results to the network device as label data for AI model training. During the inference stage using the trained AI model, the network device only needs to configure part of the reference signals in the reference signal set, and send them to the terminal device through part of the transmission beam for beam measurement and reporting. The information reported by the terminal device needs to include information about this part of the reference signal, but there is currently no solution for how the network device informs the terminal device about the information about this part of the reference signal.

[0009] To address at least one of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving information.

[0064] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] FIG2 is a schematic diagram of transmit and receive beams in a communication system according to various embodiments of the present application. As shown in FIG2 , in a communication system 100, taking a downlink channel as an example, a network device 101 may have M1 downlink transmit beams DL TX, and a terminal device 102 may have N1 downlink receive beams DL RX.

[0071] In an embodiment of the present application, as shown in FIG2 , a model 201 for predicting beam measurement results can be deployed in network device 101 or terminal device 102.

[0073] 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.

[0074] Embodiments of the first aspect

[0075] An embodiment of the present application provides a method for sending and receiving information, which is explained from the terminal device side, and the AI ​​model is deployed on the terminal device side.

[0076] FIG3 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0077] 301. The terminal device sends a request indication message for obtaining a first reference signal set to the network device;

[0078] 302. The terminal device receives a first reference signal in a first reference signal set sent by the network device.

[0079] It is worth noting that FIG3 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 FIG3 above.

[0080] In some embodiments, an AI model for beam prediction is deployed in a terminal device. The AI ​​model is used to predict the optimal beam pair based on a small number of beam pair measurement results. The input parameter of the AI ​​model is the RSRP (Reference Signal Receiving Power) value of some beam pairs, or it can be the SINR (Signal to Interference plus Noise Ratio) value of some beam pairs. The physical quantity of the output parameter is the RSRP or SINR of all beam pairs. Figure 4 is a schematic diagram of the transmitting beam, receiving beam and AI model in an embodiment of the present application. As shown in Figure 4, for example, there are 12 downlink transmitting beams and 8 downlink receiving beams, for a total of 96 beam pairs. Through configuration, the UE only measures the RSRP of 24 beam pairs (6 downlink transmitting beams and 4 downlink receiving beams). At this time, the dimension of the input parameter of the AI ​​model is 24, the physical quantity is RSRP or SINR, the dimension of the output parameter is 96, and the physical quantity is also RSRP or SINR. The optimal beam pair can be selected from the prediction results.

[0081] That is to say, in the inference stage of the AI ​​model, the measurement results of all transmitted beams are not required, only the measurement results of some transmitted beams are required. The terminal device only needs to receive the reference signal sent by the part of the transmitted beam (also called partial reference signal or first reference signal) to perform beam measurement, and the prediction result can be obtained. Since the AI ​​model is deployed on the terminal device side, the network device does not know which partial reference signals are required by the AI ​​model on the terminal device side. To this end, in an embodiment of the present application, the terminal device can send a request indication information to the network device to obtain the first reference signal set.

[0082] Through the above embodiment, the terminal device sends a request indication information for obtaining the part of the reference signal to the network device, thereby informing the network device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0083] The following is a detailed description. In the following description, reference signal and measurement resource or resource can be replaced with each other.

[0084] In some embodiments, the network device configures measurement resources (reference signals) for the measurement of the downlink transmission beam through first resource configuration information. The measurement resources (reference signals) can be reference signals such as CSI-RS and / or SSB. For example, the configured measurement resources are a resource set list (reference signal set), and each resource set consists of one or more measurement resources (reference signals). In other words, the network device can configure multiple reference signals for the terminal device for beam measurement. The first resource configuration information includes a reference signal set identifier (measurement resource set identifier) ​​and an identifier of one or more measurement resources (reference signals) constituting the reference signal set (measurement resource) set.

[0085] For example, when the reference signal is a CSI-RS, the first resource configuration information may be non-zero power CSI-RS resource set configuration information, and NZP-CSI-RS-ResourceSet may be represented using the abstract syntax notation ASN.1 data format as follows:

[0086]

[0087] That is, nzp-CSI-ResourceSetId represents the reference signal set identifier, and SEQUENCE(SIZE(1..maxNrofNZP-CSI-RS-ResourcesPerSet))OF NZP-CSI-RS-ResourceId represents the identifier of each reference signal in the reference signal set.

[0088] For example, when the reference signal is SSB, the first resource configuration information may be CSI-SSB-ResourceSet, which may be represented using the Abstract Syntax Notation (ASN.1) data format as follows:

[0089]

[0090]

[0091] That is, csi-SSB-ResourceSetId represents the reference signal set identifier, and SEQUENCE(SIZE(1..maxNrofCSI-SSB-ResourcePerSet))OF SSB-Index represents the identifier of each reference signal in the reference signal set.

[0092] In some embodiments, the first resource configuration information is carried by RRC signaling, and the reference signal set configured therein can also be understood as the full set of reference signals used for beam measurement. The training phase of the AI ​​model requires all reference signals in the reference signal set to perform beam measurement results.

[0093] In some embodiments, in 301, a request indication information for obtaining a first reference signal set is sent to a network device. The first reference signal in the first reference signal set is one or more reference signals in the reference signal set. The first reference signal set may also be referred to as a reference signal subset. The terminal device may select one or more reference signals from the reference signal set as the first reference signal set according to the requirements of the AI ​​model, and send a request indication information for obtaining the first reference signal set to the network device.

[0094] In some embodiments, the request indication information includes an identifier of a first reference signal in the first reference signal set, or the request indication information indicates the first reference signal set in the configured reference signal set by means of a bitmap or starting position and interval information. The request indication information may be carried by an RRC or MAC CE or UCI.

[0095] The following explains them separately.

[0096] For example, the request indication information includes the identifier of the first reference signal in the first reference signal set, where the identifier of the first reference signal is CRI or SSB-RI. The request indication information may also include a reference signal set identifier, where the reference signal set identifier is nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId. Figure 5 is an example diagram of the request indication information. As shown in Figure 5, the request indication information includes a reference signal set identifier as nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId, and identifiers of K first reference signals in the first reference signal set CRI / SSB-RI#1, CRI / SSB-RI#2,..., CRI / SSB-RI#K. The request indication information gives the identifier of each first reference signal in the form of a list. In this embodiment, the request indication information may be a newly added RRC signaling or an information element newly added in the existing RRC signaling or UCI. The embodiments of the present application are not limited to this.

[0097] For example, the request indication information indicates the first reference signal set in the configured reference signal set in the form of a bit map. The number of bits in the bit map can be determined according to the number of reference signals in the reference signal set. Each bit corresponds to a reference signal in the reference signal set. The value of the bit is used to indicate whether the corresponding reference signal is the first reference signal (or used to indicate whether the reference signal corresponding to the bit is included in the first reference signal set). For example, when the bit value is 0, it indicates that the reference signal is not the first reference signal and is not included in the first reference signal set. When the bit value is 1, it indicates that the reference signal is the first reference signal and is included in the first reference signal set, and vice versa. The request indication information may also include a reference signal set identifier, which is nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId. Figure 6 is an example diagram of the request indication information. As shown in Figure 6, the request indication information includes a reference signal set identifier (ID) of nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId. There are N reference signals in the reference signal set corresponding to the reference signal set identifier. The request indication information also includes N bits, and the N bits correspond to reference signal #0, reference signal #1..., reference signal #N in the reference signal set, for example, N=8, and the bit map is 10000110. Then, reference signals #0, #5, and #6 in the reference signal set are first reference signals and are included in the first reference signal set, or the bit map is 10000110 indicating that the first reference signal in the first reference signal set includes reference signals #0, #5, and #6 in the reference signal set. In this embodiment, the request indication information can be a newly added RRC signaling or an information element newly added in the existing RRC signaling or UCI. The embodiment of the present application is not limited to this; for example, the request indication information can also be a newly added MAC CE signaling, the request indication information may also include a cell identifier (Cell ID) and / or a partial bandwidth BWP identifier (BWP ID), etc. Figure 7 is an example diagram of the request indication information. As shown in Figure 7, the request indication information includes a cell identifier, a BWP identifier, a reference signal set identifier (e.g., 6 bits), and a bit T(k) indicating whether each reference signal in the reference signal set is the first reference signal; if the value of T(k) is 0, it indicates that the reference signal corresponding to T(k) is not the first reference signal, and if it is 1, it indicates that the reference signal corresponding to it is the first reference signal, and all first reference signals constitute the first reference signal set. For example, the number of reference signals in the reference signal set is 64, the value of N is 10, and the value of k is 0 to 63.

[0098] For example, the request indication information indicates the first reference signal set in the configured reference signal set by means of a starting position and interval information, the starting position offset indicates the index position of the first reference signal indicated as the first reference signal in the reference signal set, and the interval information interval indicates the interval of the index of the first reference signal in the reference signal set, that is, indicates the starting position and interval of the index of the first reference signal set in the reference signal set. The request indication information may also include a reference signal set identifier, which is nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId. Figure 8A is an example diagram of the request indication information. As shown in Figure 8A, the request indication information includes a reference signal set identifier of nzp-CSI-RS-ResourceSetId or CSI-SSB-ResourceSetId, and the reference signal set corresponding to the reference signal set identifier has N=64 reference signals. The request indication information also includes a starting position offset m of 2 and an interval information interval n of 8. Then, the reference signals indexed as #2, #10, #18, #26, #34, #42, #50, and #58 in the reference signal set are the first reference signals, or the reference signals indexed as #2, #10, #18, #26, #34, #42, #50, and #58 in the reference signal set constitute the first reference signal set. In this embodiment, the request indication information can be a newly added RRC signaling or an information element newly added in the existing RRC signaling or UCI. The embodiments of the present application are not limited to this. For example, the request indication information may also be newly added MAC CE signaling, and the request indication information may also include a cell identifier and / or a partial bandwidth BWP identifier, etc. FIG8B is an example diagram of the request indication information. As shown in FIG8B , the request indication information includes a cell identifier, a BWP identifier, a reference signal set identifier (e.g., 6 bits), and a starting position offset and interval information interval; for example, if the number of reference signals in the reference signal set is 64, the starting position offset and interval information interval values ​​range from 0 to 63, also represented by 6 bits.

[0099] In some embodiments, after receiving the request indication information, the network device may directly send each first reference signal in the first reference signal set indicated by the request indication information, or may send second resource configuration information before sending the first reference signal in the first reference signal set, wherein the second resource configuration information includes identification indication information of the first reference signal in the first reference signal set, and may optionally also include the identification of the first reference signal set, and / or the identification of the reference signal set in the first resource configuration information corresponding to the first reference signal set, wherein the second resource configuration information may be newly added signaling, and may be sent separately from the first resource configuration information, which are illustrated below with examples.

[0100] In some embodiments, when the second resource configuration information is newly added signaling, the implementation of the second resource configuration information is similar to that of the first resource configuration information. For example, the reference signal set identifier in the first resource configuration information is replaced with the first reference signal set identifier, and the identifiers of each reference signal in the reference signal set are replaced with the identifiers of each first reference signal in the first reference signal set (as the identifier indication information of the first reference signal), or the identifier indication information of the first reference signal in the second resource configuration information indicates the first reference signal in the configured reference signal set by means of a bitmap or starting position and interval information. The second resource configuration information is carried through RRC signaling, and examples are given below.

[0101] For example, when the reference signal is CSI-RS, the first resource configuration information may be non-zero power CSI-RS resource set configuration information, and the newly added second resource configuration information NZP-CSI-RS-ResourceSubSet may be expressed in the abstract syntax notation ASN.1 data format as follows:

[0102]

[0103] As shown above, the information element of the second resource configuration information NZP-CSI-RS-ResourceSubSet may include the identifier of the first reference signal set nzp-CSI-ResourceSubSetId, the identifier of the reference signal set in the first resource configuration information corresponding to the first reference signal set nzp-CSI-ResourceSetId, and the identification indication information nzp-CSI-RS-Resources-subset of the first reference signal in the first reference signal set. The identification indication information nzp-CSI-RS-Resources-subset of the first reference signal in the first reference signal set is indicated by a bitmap corresponding to the reference signal set of the first reference signal, with a length of maxNrofNZP-CSI-RS-ResourcesPerSet. A bit value of 0 in the bitmap indicates that the reference signal corresponding to the bit is not included in the first reference signal set, and a bit value of 1 indicates that the reference signal corresponding to the bit is included in the first reference signal set, and vice versa. It should be noted that other configuration information of the first reference signal set, such as repetition, aperiodicTriggeringOffset, etc., can be consistent with the configuration of the reference signal set in the first resource configuration information corresponding to the first reference signal set by default, that is, the corresponding information element configuration in the first resource configuration information can be reused without additional configuration.

[0104] For another example, when the reference signal is CSI-RS, the first resource configuration information may be non-zero power CSI-RS resource set configuration information, and the newly added second resource configuration information NZP-CSI-RS-ResourceSubSet may also be expressed using the Abstract Syntax Notation ASN.1 data format as follows:

[0105]

[0106]

[0107] That is to say, the information element of the second resource configuration information NZP-CSI-RS-ResourceSubSet may include the identifier of the first reference signal set nzp-CSI-ResourceSubSetId, the identifier of the reference signal set in the first resource configuration information corresponding to the first reference signal set nzp-CSI-ResourceSetId, and the identification indication information nzp-CSI-RS-Resources-subset of the first reference signal in the first reference signal set. The identification indication information of the first reference signal in the first reference signal set is indicated by the offest field and intveral field corresponding to the reference signal set of the first reference signal, which are respectively used to indicate the starting position and interval of the index of the first reference signal set in the reference signal set. It should be noted that the offset and interval fields are integers, and their range is determined according to maxNrofNZP-CSI-RS-ResourcesPerSet. It should be noted that continuous integers are used to define the data types of offset and interval, and other data types may also be used, such as enumeration types. The embodiments of the present application are not limited to this. It should be noted that other configuration information of the first reference signal set, such as repetition, aperiodicTriggeringOffset, etc., can be consistent with the configuration of the reference signal set in the first resource configuration information corresponding to the first reference signal set by default, that is, the corresponding information element configuration in the first resource configuration information can be reused without additional configuration.

[0108] For example, when the reference signal is SSB, the first resource configuration information may be CSI-SSB-ResourceSet, and the newly added second resource configuration information CSI-SSB-ResourceSubSet may be expressed in the abstract syntax notation ASN.1 data format as follows:

[0109]

[0110] That is to say, the information element of the second resource configuration information CSI-SSB-ResourceSubSet may include the identifier of the first reference signal set csi-SSB-ResourceSubSetId, the identifier of the reference signal set in the first resource configuration information corresponding to the first reference signal set csi-SSB-ResourceSetId, and the identification indication information csi-SSB-Resources-subset of the first reference signal in the first reference signal set. The identification indication information of the first reference signal in the first reference signal set is indicated by a bitmap corresponding to the reference signal set of the first reference signal, with a length of maxNrofCSI-SSB-ResourcesPerSet. Each bit value in the bitmap is 0, indicating that the reference signal corresponding to the bit is not included in the first reference signal set, and the bit value is 1, indicating that the reference signal corresponding to the bit is included in the first reference signal set, and vice versa. It should be noted that other configuration information of the first reference signal set can be consistent with the configuration of the reference signal set in the first resource configuration information corresponding to the first reference signal set by default, that is, the corresponding information element configuration in the first resource configuration information can be reused without additional configuration.

[0111] For example, when the reference signal is SSB, the first resource configuration information may be CSI-SSB-ResourceSet, and the newly added second resource configuration information CSI-SSB-ResourceSubSet may also be expressed using the Abstract Syntax Notation ASN.1 data format as follows:

[0112]

[0113] That is to say, the information element of the second resource configuration information CSI-SSB-ResourceSubSet may include the identifier of the first reference signal set csi-SSB-ResourceSubSetId, the identifier of the reference signal set in the first resource configuration information corresponding to the first reference signal set csi-SSB-ResourceSetId, and the identifier indication information csi-SSB-Resources-subset of the first reference signal in the first reference signal set. Among them, the identifier indication information of the first reference signal in the first reference signal set is indicated by the offest field and intveral field corresponding to the reference signal set of the first reference signal, which are respectively used to indicate the starting position and interval of the index of the first reference signal set in the reference signal set. It should be noted that the offset and interval fields are integers, and their range is determined according to maxNrofCSI-SSB-ResourcesPerSet. It should be noted here that continuous integers are used to define the data types of offset and interval, and other data types, such as enumeration types, may also be used. The embodiments of the present application are not limited to this. It should be noted that other configuration information of the first reference signal set can be consistent with the configuration of the reference signal set in the first resource configuration information corresponding to the first reference signal set by default, that is, the corresponding information element configuration in the first resource configuration information can be reused without additional configuration.

[0114] In some embodiments, when the second resource configuration information is newly added signaling, the second resource configuration information may also be implemented through MAC CE signaling. For example, after the first resource configuration information is configured through RRC signaling, MAC CE is used to activate / deactivate the reference signal in the reference signal set, so as to indirectly indicate the resource configuration of each first reference signal in the first reference signal set. The method for activating / deactivating the reference signal in the reference signal set through MAC CE signaling may be indicated by a bitmap or starting position and interval information. For example, a bitmap or starting position and interval information is used to indicate whether each reference signal in the reference signal set is activated or deactivated, that is, a bitmap or starting position and interval information is used to indicate the activated reference signal in the reference signal set, and the activated reference signal is used as the first reference signal in the first reference signal set. The specific implementation method is similar to the MAC CE signaling implementation method of the request indication information, and will not be repeated here.

[0115] It should be noted that the above field names are only examples and the embodiments of this application are not limited thereto.

[0116] In some embodiments, the request indication information is sent after the first resource configuration information (excluding the second resource configuration information) but before the second resource configuration information.

[0117] In some embodiments, in 302, the network device sends the first reference signal on a downlink channel based on the first resource configuration information and the request indication information, or based on the second resource configuration information. That is, the terminal device receives the corresponding first reference signal on the corresponding time-frequency resource according to the time-frequency resource, period, and other information mapped to the first reference signal configured in the resource configuration information, and performs beam measurement on the first reference signal in the first reference signal set. The result of the beam measurement is used for inference of the AI ​​model.

[0118] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0119] Through the above embodiment, the terminal device sends a request indication information for obtaining the part of the reference signal to the network device, thereby informing the network device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0120] Embodiments of the second aspect

[0121] An embodiment of the present application provides a method for sending and receiving information, which is explained from the network device side. The AI ​​model is deployed on the terminal device side. The content that is the same as the embodiment of the first aspect will not be repeated.

[0122] FIG11 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG11 , the method includes:

[0123] 1101. A network device receives request indication information sent by a terminal device for obtaining a first reference signal set;

[0124] 1102. The network device sends a first reference signal in a first reference signal set to the terminal device.

[0125] It is worth noting that FIG11 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 FIG11 above.

[0126] In some embodiments, the implementation of 1101-1102 corresponds to 301-302 and will not be repeated here.

[0127] In some embodiments, the implementation of the above-mentioned request indication information can refer to the embodiment of the first aspect. The network device can also send first resource configuration information and second resource configuration information to the terminal device. The implementation thereof can refer to the embodiment of the first aspect and will not be repeated here.

[0128] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0129] Through the above embodiment, the terminal device sends a request indication information for obtaining the part of the reference signal to the network device, thereby informing the network device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0130] The above methods for sending and receiving information between a terminal device and a network device in the embodiments of the first aspect and the second aspect are as follows:

[0131] FIG9 is a schematic diagram of a method for sending and receiving information in an embodiment of the present application. As shown in FIG9 , the method includes:

[0132] 901, the network device sends first resource configuration information to the terminal device;

[0133] 902. The network device sends measurement reporting configuration information to the terminal device.

[0134] 903, the terminal device sends a request indication message to the network device;

[0135] 904, the network device sends second resource configuration information to the terminal device;

[0136] 905. The network device sends a first reference signal in a first reference signal set to the terminal device.

[0137] 906. The terminal device performs beam measurement using the first reference signal.

[0138] 907, the terminal device sends the measurement results as input to the AI ​​model to obtain the prediction results;

[0139] 908. The terminal device sends beam measurement reporting information to the network device;

[0140] 909. The network device sends downlink data to the terminal device.

[0141] In some embodiments, the implementation of 903 and 905 can refer to 301-302, and the repeated parts will not be repeated.

[0142] In some embodiments, in 902, the parameters required for measurement reporting are configured, including: reporting quantity, measurement constraint configuration, codebook configuration, group-based reporting configuration, reporting period, etc. For example, when beam management is required, the reporting quantity is a combination of the following parameters: CRI-RSRP / SINR (beam management based on CSI-RS) or SSBRI-RSRP / SINR (beam management based on SSB); in 906, the terminal device measures the L1-RSRP or SINR of the corresponding downlink transmit beam through the first reference signal as a measurement result. In 907, the terminal device inputs the measurement result into the AI ​​model to predict one or more optimal downlink beam pairs. In 908, the terminal device sends beam measurement reporting information (carried by UCI) in the corresponding time-frequency resources. The reporting information includes the results predicted by the AI ​​model, for example, downlink transmit beam information of one or more predicted optimal downlink beam pairs and the corresponding measurement results. For example, the reporting information includes the measurement result RSRP (Reference Signal Receiving Power, reference signal received power) values ​​#1, #2, #3, #4, and the synchronization signal block resource indicator (SSB resource indicator, SSB RI) or channel state information reference signal resource indicator (CSI-RS resource indicator, CRI) #1, #2, #3, #4 associated with the measurement result RSRP. Since the network device side knows the correspondence between SSB RI or CRI and the downlink transmission beam, the SSB RI or CRI can implicitly indicate one or several predicted optimal downlink transmission beams. So that the network device in 909 uses the downlink transmission beam to send downlink data, the terminal device selects the downlink receiving beam corresponding to the downlink transmission beam to receive the downlink data according to the indication information about the downlink transmission beam in the TCI (transmission configuration indicator) signaling.

[0143] FIG10 is a schematic diagram of a method for sending and receiving information in an embodiment of the present application. As shown in FIG10 , the method includes:

[0144] 1001. The network device sends first resource configuration information to the terminal device.

[0150] 1007. The terminal device sends beam measurement reporting information to the network device.

[0151] 1008. The network device sends downlink data to the terminal device.

[0152] The similarities between FIG. 10 and FIG. 9 are not repeated here. The difference is that the network device does not need to send the second resource configuration information, and directly sends the first reference signal in the first reference signal set according to the request indication information.

[0153] Embodiments of the third aspect

[0154] An embodiment of the present application provides a method for sending and receiving information, which is explained from the perspective of a network device, and the AI ​​model is deployed on the network device side.

[0155] FIG12 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG12 , the method includes:

[0156] 1201. A network device sends third resource configuration information to a terminal device, where the third resource configuration information includes a reference signal set identifier and an identifier of each reference signal in the reference signal set.

[0157] 1202. The network device sends first reference signal set indication information to the terminal device;

[0158] 1203. The network device sends a first reference signal in a first reference signal set to the terminal device.

[0159] It is worth noting that FIG12 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 FIG12 above.

[0160] In some embodiments, an AI model for beam prediction is deployed in a network device. The AI ​​model is used to predict the optimal beam pair based on a small number of beam pair measurement results. The input parameter of the AI ​​model is the RSRP (Reference Signal Receiving Power) value of some beam pairs, or it can be the SINR (Signal to Interference plus Noise Ratio) value of some beam pairs. The physical quantity of the output parameter is the RSRP or SINR of all beam pairs. This model is the same as the AI ​​model shown in Figure 4 and will not be repeated here.

[0161] That is, during the inference phase of the AI ​​model, the network device only needs to configure some reference signals in the reference signal set and send them to the terminal device via some transmit beams for beam measurement and reporting. The information reported by the terminal device needs to include information about these reference signals. To this end, in this embodiment of the present application, the network device sends first reference signal set indication information to the terminal device.

[0162] Through the above embodiment, the network device sends indication information about the part of the reference signal to the terminal device, thereby informing the terminal device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0163] The following is a detailed description. In the following description, reference signal and measurement resource or resource can be replaced with each other.

[0164] In some embodiments, the network device configures measurement resources (reference signals) for the measurement of the downlink transmission beam through third resource configuration information. The measurement resources (reference signals) can be reference signals such as CSI-RS and / or SSB. For example, the configured measurement resources are a resource set list (reference signal set), and each resource set consists of one or more measurement resources (reference signals). In other words, the network device can configure multiple reference signals for the terminal device for beam measurement. The third resource configuration information includes a reference signal set identifier (measurement resource set identifier) ​​and an identifier of one or more measurement resources (reference signals) constituting the reference signal set (measurement resource) set. The implementation method of the third resource configuration information can refer to the implementation method of the first resource configuration information in the embodiment of the first aspect, and will not be repeated here.

[0165] In some embodiments, in 1202, the network device sends first reference signal set indication information to the terminal device. For the meaning of the first reference signal, please refer to the embodiment of the first aspect.

[0166] In some embodiments, the first reference signal set indication information includes an identifier of a first reference signal in the first reference signal set, or the first reference signal set indication information indicates the first reference signal set in a configured reference signal set by means of a bitmap or starting position and interval information, or the first reference signal set indication information indicates an activated reference signal in a reference signal set, and the activated reference signal serves as the first reference signal in the first reference signal set. The first reference signal set indication information may be carried by an RRC or MAC CE or DCI.

[0167] In some embodiments, the first reference signal set indication information is included in the third resource configuration information or is not included in the third resource configuration information. For example, the first reference signal set indication information may be newly added RRC signaling or MAC CE signaling, and the first reference signal set indication information is not included in the third resource configuration information, but is sent separately from the third resource configuration information; or, for example, the first reference signal set indication information may be a newly added information element, and the first reference signal set indication information is included in the third resource configuration information and is sent together with the third resource configuration information. The embodiments of the present application are not limited to this.

[0168] In some embodiments, when the first reference signal set indication information is newly added signaling, its implementation can refer to the second resource configuration information in the embodiment of the first aspect, and will not be further described here. When the first reference signal set indication information is a newly added information element included in the third resource configuration information and transmitted together with the third resource configuration information, its indication method also includes the following examples, which are described in detail below.

[0169] In some embodiments, the first reference signal set indication information is a newly added information element in the third resource configuration information, and the newly added information element includes the identifier of the first reference signal in the first reference signal set, or indicates the first reference signal set in the configured reference signal set by means of a bit map or starting position and interval information.

[0170] For example, when the reference signal is a CSI-RS, the third resource configuration information may be non-zero power CSI-RS resource set configuration information, and NZP-CSI-RS-ResourceSet may be represented using the Abstract Syntax Notation ASN.1 data format as follows:

[0171]

[0172] That is to say, if a field nzp-CSI-RS-Resources-subset (first reference signal set indication information) is added to NZP-CSI-RS-ResourceSet (third resource configuration information), it is represented by a bit map with a length of maxNrofNZP-CSI-RS-ResourcesPerSet. A bit value of 0 in the bit map indicates that the reference signal corresponding to the bit is not included in the first reference signal set, and a bit value of 1 indicates that the reference signal corresponding to the bit is included in the first reference signal set, and vice versa.

[0173] For example, when the reference signal is a CSI-RS, the third resource configuration information may be non-zero power CSI-RS resource set configuration information, and NZP-CSI-RS-ResourceSet may be represented using the abstract syntax notation ASN.1 data format as follows:

[0174]

[0175]

[0176] That is to say, for example, a field nzp-CSI-RS-Resources-subset (first reference signal set indication information) is added to NZP-CSI-RS-ResourceSet (third resource configuration information), which includes two fields: starting position offset and interval information inverval, which are used to indicate the starting position and interval of the first reference signal in the first reference signal set indexed in the reference signal set, where the offset and interval fields are integers, and their range is determined according to maxNrofNZP-CSI-RS-ResourcesPerSet. It should be noted that continuous integers are used to define the data types of offset and interval, and other data types, such as enumeration types, may also be used. The embodiments of the present application are not limited to this.

[0177] For example, when the reference signal is SSB, the third resource configuration information may be CSI-SSB-ResourceSet, which may be represented using the Abstract Syntax Notation (ASN.1) data format as follows:

[0178]

[0179] That is to say, if a field CSI-SSB-Resources-subset (first reference signal set indication information) is added to CSI-SSB-ResourceSet (third resource configuration information), it is represented by a bit map with a length of maxNrofCSI-SSB-ResourcesPerSet. A bit value of 0 in the bit map indicates that the reference signal corresponding to the bit is not included in the first reference signal set, and a bit value of 1 indicates that the reference signal corresponding to the bit is included in the first reference signal set, and vice versa.

[0180] For example, when the reference signal is SSB, the third resource configuration information may be CSI-SSB-ResourceSet, which may be represented using the Abstract Syntax Notation (ASN.1) data format as follows:

[0181]

[0182] That is to say, if a field CSI-SSB-Resources-subset (first reference signal set indication information) is added to CSI-SSB-ResourceSet (third resource configuration information), it includes two fields: starting position offset and interval information inverval, which are used to indicate the starting position and interval of the first reference signal in the first reference signal set indexed in the reference signal set, where the offset and interval fields are integers, and their range is determined according to maxCSI-SSB-ResourcesPerSet. It should be noted that continuous integers are used to define the data types of offset and interval, and other data types may also be used, such as enumeration types. The embodiments of the present application are not limited to this.

[0183] In the above embodiment (newly added information element), when the third resource configuration information includes the first reference signal set indication information, it indicates that the information of the first reference signal set needs to be configured, such as when it is applied in a scenario where an AI model is deployed. When the third resource configuration information does not include the first reference signal set indication information, it indicates that the information of the first reference signal set does not need to be configured, such as when it is applied in a scenario where an AI model is not deployed.

[0184] In some embodiments, in 1203, the network device transmits the first reference signal on a downlink channel based on the first reference signal set indication information. That is, the terminal device receives the corresponding first reference signal on the corresponding time-frequency resource based on information such as the time-frequency resource and period mapped to the first reference signal, and performs beam measurement on the first reference signal in the first reference signal set. The network device receives a measurement result of the beam measurement performed on the first reference signal in the first reference signal set reported by the terminal device, and the beam measurement result is used for inference of the AI ​​model.

[0185] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0186] Through the above embodiment, the network device sends indication information about the part of the reference signal to the terminal device, thereby informing the terminal device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0187] Embodiments of the fourth aspect

[0188] An embodiment of the present application provides a method for sending and receiving information, which is explained from the terminal device side. The AI ​​model is deployed on the network device side. The content that is the same as the embodiment of the third aspect will not be repeated.

[0189] FIG13 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG13 , the method includes:

[0190] 1301. A terminal device receives third resource configuration information sent by a network device, where the third resource configuration information includes a reference signal set identifier and an identifier of each reference signal in the reference signal set.

[0191] 1302. The terminal device receives first reference signal set indication information sent by the network device;

[0192] 1303. The terminal device receives the first reference signal in the first reference signal set sent by the network device.

[0193] It is worth noting that FIG13 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 FIG13 above.

[0194] In some embodiments, the implementation of 1301-1302 corresponds to 1201-1202 and will not be repeated here.

[0195] In some embodiments, the implementation of the above-mentioned first reference signal set indication information can refer to the embodiment of the third aspect and will not be repeated here.

[0196] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0197] Through the above embodiment, the network device sends indication information about the part of the reference signal to the terminal device, thereby informing the terminal device of the information of the part of the reference signal used in the AI ​​model inference stage, and can effectively use the AI ​​model to predict the optimal beam pair, which can greatly reduce the system load and delay caused by the beam measurement.

[0198] The above methods for sending and receiving information between a terminal device and a network device in the embodiments of the third aspect and the fourth aspect are as follows:

[0199] FIG14 is a schematic diagram of a method for sending and receiving information in an embodiment of the present application. As shown in FIG14 , the method includes:

[0200] 1401, the network device sends third resource configuration information to the terminal device;

[0201] 1402. The network device sends measurement reporting configuration information to the terminal device.

[0202] 1403. The network device sends first reference signal set indication information (configuring the first reference signal or activating the first reference signal) to the terminal device.

[0203] 1404. The network device sends a first reference signal in a first reference signal set to the terminal device.

[0204] 1405. The terminal device performs beam measurement using the first reference signal.

[0205] 1406. The terminal device sends beam measurement reporting information to the network device.

[0206] At 1407, the network device sends the measurement results as input to the AI ​​model to obtain a prediction result;

[0207] 1408, the network device sends downlink data to the terminal device;

[0208] The difference from the implementation method in Figure 9 is that since the AI ​​model is deployed on the network device side, the network device can select the first reference signal according to the AI ​​model requirements, without the terminal device informing the first reference signal through request indication information, and the network device sends the first reference signal set indication information to the terminal device; in addition, since the AI ​​model is deployed on the network device side, in 1407-1408, the output of the AI ​​model is the prediction result of all beam pairs, and the optimal downlink transmission beam can be selected from the prediction results, and the network device uses the optimal downlink transmission beam to send downlink data.

[0209] FIG15 is a schematic diagram of a method for sending and receiving information in an embodiment of the present application. As shown in FIG15 , the method includes:
