[0066] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function.

[0067] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0068] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0069] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0070] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0071] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0072] To facilitate a better understanding of the embodiments of the present application, the neural network and machine learning related to the present application are explained.

[0073] A neural network (NN) is a computational model consisting of multiple interconnected neuron nodes, where the connections between nodes represent weighted values ​​from input signals to output signals, called weights. Each node performs weighted summation (SUM) on different input signals and outputs them through a specific activation function (f). Figure 2 is a schematic diagram of a neuron structure, where a1, a2, …, an represent input signals, w1, w2, …, wn represent weights, f represents the activation function, and t represents the output.

[0074] A simple neural network, shown in Figure 3, consists of an input layer, hidden layers, and an output layer. By using different connections, weights, and activation functions among multiple neurons, different outputs can be generated, thereby fitting the mapping relationship from input to output. Each node in the previous level is connected to all nodes in the next level. This neural network is a fully connected neural network, also known as a deep neural network (DNN).

[0075] The basic structure of a convolutional neural network (CNN) consists of an input layer, multiple convolutional layers, multiple pooling layers, a fully connected layer, and an output layer, as shown in Figure 4. Each neuron in the convolutional kernel of a convolutional layer is locally connected to its input. The introduction of a pooling layer extracts the local maximum or average features of a layer, effectively reducing network parameters and exploiting local features, enabling the CNN to converge quickly and achieve excellent performance.

[0076] Deep learning utilizes deep neural networks with multiple hidden layers, significantly improving the network's ability to learn features and fitting complex, nonlinear mappings from input to output. Consequently, it has found widespread application in speech and image processing. In addition to deep neural networks, deep learning also includes other commonly used basic structures such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs) for different tasks.

[0077] The basic structure of a convolutional neural network includes an input layer, multiple convolutional layers, multiple pooling layers, a fully connected layer, and an output layer, as shown in Figure 4. Each neuron in the convolution kernel of the convolutional layer is locally connected to its input, and the introduction of the pooling layer extracts the local maximum or average features of a certain layer, effectively reducing the network parameters and mining local features, enabling the convolutional neural network to converge quickly and achieve excellent performance.

[0078] RNNs are neural networks that model sequential data and have achieved remarkable success in natural language processing applications such as machine translation and speech recognition. Specifically, network devices memorize information from past moments and use it in the calculation of current outputs. This means that nodes in hidden layers are no longer disconnected but connected, and the input to a hidden layer includes not only the input layer but also the output of the previous hidden layer. Common RNN structures include long short-term memory (LSTM) and gated recurrent unit (GRU). Figure 5 shows a basic LSTM cell structure, which can include a tanh activation function. Unlike RNNs, which only consider the most recent state, the LSTM cell state determines which states should be retained and which should be forgotten, addressing the long-term memory limitations of traditional RNNs.

[0079] To facilitate a better understanding of the embodiments of the present application, the beam management related to the present application is explained.

[0080] The NR system introduces millimeter-wave frequency band communications and corresponding beam management mechanisms, including uplink and downlink beam management. Downlink beam management includes downlink beam scanning, optimal beam reporting on the UE side, and downlink beam indication on the network side.

[0081] The downlink beam scanning process refers to the network device scanning different transmit beam directions using downlink reference signals. The UE can use different receive beams for measurement, thereby traversing all beam pairs. The UE calculates the Layer 1 Reference Signal Received Power (L1-RSRP) value corresponding to each beam pair.

[0082] The downlink reference signal includes a synchronization signal block (Synchronization Signal Block, SSB) and / or a channel state information reference signal (Channel State Information Reference Signal, CSI-RS).

[0083] To facilitate a better understanding of the embodiments of the present application, the beam management related to the present application is explained.

[0084] The introduction of millimeter-wave frequency band communications in NR systems also introduces beam management mechanisms. These include uplink and downlink beam management. Downlink beam management includes downlink beam sweeping, UE beam measurement and reporting, and downlink beam indication by network equipment.

[0085] The downlink beam scanning process may include three processes, namely P1, P2 and P3 processes. The P1 process refers to the network device scanning different transmit beams and the UE scanning different receive beams; the P2 process refers to the network device scanning different transmit beams and the UE using the same receive beam; the P3 process refers to the network device using the same transmit beam and the UE scanning different receive beams. Generally, the network device completes the above beam scanning process by sending a downlink reference signal. Optionally, the downlink reference signal may include but is not limited to a synchronization signal block (SSB) and / or a channel state information reference signal (CSI-RS).

[0086] FIG6 is a schematic diagram of the P1 process (or called the downlink full scan process), FIG7 is a schematic diagram of the P2 process, and FIG8 is a schematic diagram of the P3 process.

[0087] As shown in FIG6 , in the P1 process, the network device traverses all transmit beams to send downlink reference signals, and the UE side traverses all receive beams to perform measurements and determine corresponding measurement results.

[0088] As shown in Figure 7, in the P2 process, the network device traverses all transmit beams to send downlink reference signals, and the UE side uses a specific receive beam to perform measurements to determine the corresponding measurement results.

[0089] As shown in Figure 8, in the P3 process, the network device can use a specific transmit beam to send a downlink reference signal, and the UE side traverses all receive beams to perform measurements and determine the corresponding measurement results.

[0090] Beam reporting means that the UE measures the results of different beams or beam pairs, selects the K transmit beams with the best measurement results, and reports them to the network device.

[0091] After the network device learns the optimal beam reported by the terminal device, it can carry the Transmission Configuration Indicator (TCI) status (which contains the transmit beam with the downlink reference signal as a reference) through Media Access Control (MAC) or Downlink Control Information (DCI) signaling to complete the beam indication to the UE. The UE uses the receive beam corresponding to the transmit beam for downlink reception.

[0092] For the downlink full scan process, also known as the P1 process, the UE needs to traverse all combinations of transmit and receive beams, which incurs significant overhead and latency. For example, if the network equipment deploys 64 different downlink transmit beams in the FR2 frequency band (carried by up to 64 SSBs), the UE uses multiple antenna panels (including a single receive beam panel) to simultaneously scan the receive beams, and each antenna panel has four receive beams. Therefore, the UE needs to measure at least 256 beam pairs, resulting in 256 resources of downlink resource overhead.

[0093] From a time perspective, each SSB cycle is approximately 20ms, so four SSB cycles are required to complete the measurement of four receiving beams (assuming that multiple receiving antenna panels can be used for beam scanning), which means at least 80ms is required.

[0094] Therefore, how to reduce the overhead and delay of beam scanning is an urgent problem that needs to be solved.

[0095] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0096] FIG9 is a schematic diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG9 , the method 200 includes the following contents:

[0097] S210: The terminal device obtains a first data set, where the first data set includes information of multiple measurement space filters, and the multiple measurement space filters belong to a measurement space filter set;

[0098] S220. Determine target information based on the first data set and the first model, wherein the target information includes information of K target spatial filters, the K target spatial filters belong to a prediction spatial filter set, the measurement spatial filter set is a subset of the prediction spatial filter set, and K is a positive integer.

[0099] In some embodiments of the present application, a spatial filter may also be referred to as a beam, a beam pair, a spatial relation, a spatial setting, a spatial domain filter, or a reference signal.

[0100] In some embodiments, the predicted spatial filter set can be a spatial filter set configured by the network device, or a full set of spatial filters, or a spatial filter set used for prediction, that is, the terminal device can predict the target spatial filter in the predicted spatial filter set based on the first model.

[0101] Optionally, the predicted spatial filter set may be a predicted beam pair set, a predicted transmit beam set, or a predicted receive beam set.

[0102] In some embodiments, the measurement spatial filter set may be a spatial filter set used for measurement, or a spatial filter set actually used for measurement, or a spatial filter set actually used for scanning. In other words, the measurement spatial filter may be a spatial filter used for measurement, or a spatial filter actually used for measurement, or a spatial filter actually used for scanning.

[0103] Optionally, the measurement spatial filter set may be a measurement beam pair set, a measurement transmit beam set, or a measurement receive beam set.

[0104] In some embodiments, the measurement spatial filter set is a subset of the prediction spatial filter set.

[0105] Therefore, in an embodiment of the present application, the terminal device only needs to measure some of the spatial filters in the predicted spatial filter set, and can predict the target spatial filter in the predicted spatial filter set based on the measurement results of the part of the spatial filters based on the first model, without having to scan all the spatial filters in the predicted spatial filter set, which is beneficial to reducing scanning overhead and delay.

[0106] In some embodiments, the measurement spatial filter is a spatial filter pair, wherein the spatial filter pair includes a transmit spatial filter (Tx spatial filter, or Tx spatial domain filter) and a receive spatial filter (Rx spatial filter, or Rx spatial domain filter).

[0107] For example, the measurement spatial filter is a beam pair (or Tx-Rx beam pair), which includes a transmit beam (Tx beam) and a receive beam (Rx beam).

[0108] In some other embodiments, the measurement spatial filter is a transmit spatial filter (Tx spatial filter, or Tx spatial domain filter).

[0109] For example, the measurement spatial filter is a transmit beam (Tx beam).

[0110] In some further embodiments, the measurement spatial filter is a receive spatial filter (Rx spatial filter, or Rx spatial domain filter).

[0111] For example, the measurement spatial filter is a receive beam (Rx beam).

[0112] In some embodiments, the information of the measurement spatial filter includes identification information of the measurement spatial filter (eg, beam index, beam pair index, or Tx-Rx pair index, etc.) and / or measurement results of the measurement spatial filter.

[0113] In some embodiments, the K target spatial filters may be considered as optimal spatial filters in the prediction spatial filter set. Alternatively, the optimal spatial filter may refer to a spatial filter in the prediction spatial filter set that meets certain conditions.

[0114] For example, the K target spatial filters may be spatial filters whose measurement results in the prediction spatial filter set meet a first threshold, or the K target spatial filters may be K spatial filters whose measurement results in the prediction spatial filter set are the highest (or optimal).

[0115] Optionally, the first threshold may be configured by the network device or predefined.

[0116] Optionally, the measurement result meeting the first threshold may include:

[0117] The measurement result is greater than the first threshold, or the measurement result is greater than or equal to the first threshold.

[0118] In some embodiments, the target spatial filter is a spatial filter pair, wherein the spatial filter pair includes a transmit spatial filter (Tx spatial filter, or Tx spatial domain filter) and a receive spatial filter (Rx spatial filter, or Rx spatial domain filter). When the first model is used to predict the optimal spatial filter pair, the purpose of the P1 process described above is consistent.

[0119] For example, the target spatial filter is a beam pair (Tx-Rx beam pair), which includes a transmit beam (Tx beam) and a receive beam (Rx beam). That is, the first model can be used to predict the optimal beam pair.

[0120] In some other embodiments, the target spatial filter is a transmit spatial filter. When the first model is used to predict the optimal transmit spatial filter, the purpose is consistent with the P2 process mentioned above.

[0121] For example, the target spatial filter is a transmit beam (Tx beam), that is, the first model can be used to predict the optimal transmit beam.

[0122] In some other embodiments, the target spatial filter is a receiving spatial filter. When the first model is used to predict the optimal receiving spatial filter pair, the purpose is consistent with the above-mentioned P3 process.

[0123] For example, the target spatial filter is a receive beam (Rx beam), that is, the first model can be used to predict the optimal receive beam.

[0124] In some embodiments, the information of the target spatial filter includes identification information of the target spatial filter (eg, beam index, beam pair index, etc.) and / or a measurement result of the target spatial filter.

[0125] In some embodiments, the K target spatial filters belong to the prediction spatial filter set, but not necessarily to the measurement spatial filter set.

[0126] It should be understood that in the embodiment of the present application, the measurement results of the spatial filters in the measurement spatial filter set are obtained by actual measurement, and the measurement results of the spatial filters in the prediction spatial filter set that do not belong to the measurement spatial filter set are predicted by the terminal device based on the first model.

[0127] In some embodiments of the present application, the measurement results of the spatial filter may include but are not limited to at least one of the following:

[0128] Layer 1 Reference Signal Receiving Power (L1-RSRP), Layer 1 Reference Signal Receiving Quality (L1-RSRQ), Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).

[0129] It should be noted that, in the embodiment of the present application, the prediction spatial filter set is referred to as Set A (Set A), and the measurement spatial filter set is referred to as Set B (Set B).

[0130] It should be understood that the present application does not limit the specific implementation of the first model, for example, it can be implemented using CNN or RNN, or it can also be implemented using other neural networks.

[0131] In some embodiments, the first model includes model A and model B. Model A is used to output identification information of K target spatial filters, such as the indexes of the optimal K beams or beam pairs, and model B is used to output measurement results of the K spatial filters, such as the measurement results of the optimal K beams or beam pairs. Model A and model B use the same input, namely, the first dataset.

[0132] FIG10 shows an example of the model structure and input and output relationship of a model A provided in an embodiment of the present application.

[0133] As shown in Figure 10, the input of model A can be the indexes of multiple beams or beam pairs and the corresponding measurement results, the labels can be the indexes of the K beams or beam pairs with the best measurement results, and the output can be the indexes of the K beams or beam pairs with the best measurement results.

[0134] FIG11 shows an example of the model structure and input and output relationship of a model B provided in an embodiment of the present application.

[0135] As shown in Figure 11, the input of model B can be the indexes of multiple beams or beam pairs and the corresponding measurement results, the label can be the measurement results of the K beams or beam pairs with the best measurement results, and the output can be the measurement results of the best K beams or beam pairs.

[0136] It should be understood that the number of beams or beam pairs output when inferring the optimal beams or beam pairs using the first model can be the same as the number of beams or beam pairs annotated when training the first model, or can be less than the number of beams or beam pairs annotated when training the first model. That is, if K beams or beam pairs were annotated when training the first model, then when inferring the optimal beams or beam pairs using the first model, K beams or beam pairs can be output, or less than K beams or beam pairs can be output.

[0137] It should be understood that the embodiments of the present application do not limit the training method of the first model. For example, it can be obtained by training on a terminal device, or it can be obtained by training on a network device and the model parameters are sent to the terminal device. Optionally, the first model is obtained by training through offline training or online training. It should be noted that offline training and online training methods are not mutually exclusive. For example, first, the network device can obtain a basic model through offline training based on a data set. During the use of the model, as the terminal device further measures and / or reports, the network device can continue to collect more data and perform real-time online training to optimize the model parameters to achieve better inference and prediction results.

[0138] FIG. 12 is an example of input and output of the first model when the optimal beam pair is predicted by the first model.

[0139] As shown in Figure 12, the dashed boxes contain eight horizontal and four vertical transmit beams. Of these 32 transmit beams, the eight pattern-filled transmit beams (8 in total) belong to Set B. The four dashed boxes correspond to different receive beams. Therefore, Set A can include 32*4 beam pairs, and Set B can include 8*4 beam pairs.

[0140] The measurement results of the beam pairs in Set B can be used as input to the first model to predict the optimal beam pairs in Set A. For example, the first model can predict the optimal K beam pairs in Set A based on the measurement results of the beam pairs in Set B.

[0141] In some embodiments of the present application, the method 200 further includes:

[0142] The terminal device sends first capability information to the network device, where the first capability information is used to indicate the capability of the spatial filter supported by the terminal device, or the spatial filter information adapted to the first model.

[0143] It should be understood that in the embodiment of the present application, the first capability information can be sent through any uplink information, uplink message or uplink channel, and the present application does not limit this.

[0144] In some embodiments, the spatial filter capabilities supported by the terminal device include at least one of the following:

[0145] The number of transmit spatial filters supported by the terminal device;

[0146] The number of receive spatial filters supported by the terminal device;

[0147] The number of spatial filter pairs supported by the terminal device.

[0148] In some embodiments, the spatial filter information adapted to the first model includes, but is not limited to, at least one of the following:

[0149] The amount of spatial filter information supported by the first model (i.e., the input dimension of the first model, or in other words, the input scale);

[0150] The size of the set of prediction spatial filters supported by the first model;

[0151] Set A supported (or recommended) by the terminal device;

[0152] Set B supported (or recommended) by the terminal device.

[0153] For example, the UE may recommend a combination of 64 transmit beams and 8 receive beams to construct Set A, and a combination of 16 transmit beams and 4 receive beams to construct Set B.

[0154] In some embodiments, the combination of Set A and Set B can be considered a capability combination of the model.

[0155] It should be understood that the embodiment of the present application does not limit the number of Set A and Set B reported by the terminal device. For example, one group of Set A and Set B may be reported, or a combination of multiple groups of Set A and Set B may be reported.

[0156] In some embodiments, the scale of the prediction spatial filter set supported by the first model may be the scale of the prediction spatial filter set used by the first model during model training.

[0157] In some embodiments, the network device may determine the number of receive beams supported by the terminal device based on the first capability information. For example, in the previous example, the network device may determine that the maximum number of receive beams adapted by the first model on the terminal device side is 8.

[0158] In some embodiments, the network device may configure a prediction spatial filter set and a measurement spatial filter set for the terminal device according to the first capability information, or may independently determine the prediction spatial filter set and the measurement spatial filter set to be configured for the terminal device.

[0159] For example, the network device can determine Set A and Set B recommended by the terminal device as Set A and Set B configured for the terminal device. Alternatively, the network device can adjust Set A and Set B reported by the terminal device to determine the final configured Set A and Set B. Continuing with the previous example, the network device can configure Set A to be a combination of 32 transmit beams and 8 receive beams, and Set B to be a combination of 8 transmit beams and 4 receive beams.

[0160] In some embodiments of the present application, the method 200 further includes:

[0161] The terminal device receives first configuration information sent by a network device, where the first configuration information is used to configure at least one prediction spatial filter set and / or at least one measurement spatial filter set.

[0162] It should be understood that in the embodiment of the present application, the first configuration information can be sent through any downlink information, downlink message or downlink channel, and the present application does not limit this. As an example, the first configuration information can be carried by Radio Resource Control (RRC).

[0163] Optionally, when the network device configures multiple prediction spatial filter sets and / or multiple measurement spatial filter sets for the terminal device, the multiple prediction spatial filter sets and / or multiple measurement spatial filter sets can be used in different scenarios. For example, as the terminal device moves, or the channel environment, or the beam adaptability changes, the network device can adjust Set A and Set B used by the first model, so that the beam prediction can adapt to changes in the beam environment.

[0164] Optionally, when the first configuration information is used to configure a set of Set A and Set B, the terminal device may perform target spatial filter prediction based on the set of Set A and Set B.

[0165] Optionally, when the first configuration information is used to configure multiple groups of Set A and / or multiple groups of Set B, the terminal device may randomly select one group of Set A and Set B for target spatial filter prediction, or may activate or update Set A and Set B used for target spatial filter prediction based on an instruction of the network device. For example, the terminal device receives first indication information sent by the network device, where the first indication information is used to indicate a target Set A among multiple groups of Set A and / or a target Set B among multiple groups of Set B.

[0166] For example, Set A is the full set of beam pairs, which may include 64 transmit beams on the network device side and 8 receive beams on the terminal device side. Set B is a subset of beam pairs, which may include, for example, 16 transmit beams on the network device side and 4 receive beams on the terminal device side. In an embodiment of the present application, the beam pairs actually measured by the terminal device are reduced from 64*8=512 beam pairs to 16*4=64 beam pairs, reducing the overhead by 1-64 / 512=87.5%.

[0167] It should be understood that in the embodiment of the present application, the first indication information can be sent through any downlink information, downlink message or downlink channel, and the present application does not limit this.

[0168] As an example, the first indication information is carried by at least one of the following signaling:

[0169] RRC signaling, Media Access Control Control Element (MAC CE), Downlink Control Information (DCI).

[0170] In some embodiments of the present application, the terminal device may also pre-process the input information of the first model.

[0171] For example, when the dimension of the first data set is inconsistent with the input dimension supported by the first model, the first data set is preprocessed to make the dimension of the input information of the first model consistent with the input dimension supported by the first model.

[0172] That is, the input information of the first model may be the first data set, or may be data after processing the first data set.

[0173] Optionally, the dimension of the first data set may refer to the amount of spatial filter information included in the first data set.

[0174] Optionally, the input dimension supported by the first model may be the number of spatial filter information supported by the first model as input.

[0175] In some embodiments of the present application, the S220 includes:

[0176] When the number of measurement spatial filter information included in the first data set is different from the number of spatial filter information supported by the first model (i.e., the input dimension of the first model), processing the plurality of measurement spatial filter information included in the first data set to obtain target input information, wherein the number of measurement spatial filter information included in the target input information is the same as the number of spatial filter information supported by the first model;

[0177] The target information is obtained by processing the target input information through the first model.

[0178] In some embodiments, when the number of information on multiple measurement spatial filters included in the first data set is less than the number of information on spatial filters supported by the first model for input, the information on the multiple measurement spatial filters is upsampled to obtain the target input information.

[0179] Optionally, the upsampling processing here may include but is not limited to filling processing, such as filling by zero padding, as shown in Figure 13, or filling by copying part of the data in the first data set, or filling by linear difference, as shown in Figure 14.

[0180] In other embodiments, when the amount of information on multiple measurement spatial filters included in the first data set is greater than the amount of information on spatial filters supported by the first model for input, the information on the multiple measurement spatial filters is downsampled to obtain target input information.

[0181] Optionally, the downsampling processing here may include, but is not limited to, eliminating redundant inputs through sampling (or puncturing), or making the dimension of the input information meet the input dimension supported by the first model through linear interpolation, as shown in Figure 15.

[0182] As an example, if the number of information on multiple measurement spatial filters included in the first data set is twice the number of information on spatial filters supported by the first model input, the information on the measurement spatial filters with odd indexes (or even indexes) in the first data set can be selected as the target input information, and other information can be ignored.

[0183] In some embodiments of the present application, the terminal device may further post-process the output information of the first model.

[0184] For example, when the size of the prediction spatial filter set configured by the network device is inconsistent with the size of the prediction spatial filter set supported by the first model, the terminal device can post-process the output information of the first model to make the accuracy of the output information of the first model the same as the accuracy of the Set A set configured by the network device.

[0185] That is, the target information may be the output information of the first model, or may be data obtained by processing the output information of the first model.

[0186] In some embodiments of the present application, the S220 includes:

[0187] When the size of the prediction spatial filter set configured by the network device is different from the size of the prediction spatial filter set supported by the first model (i.e., the scale of the prediction spatial filter set supported by the first model), the output information of the first model is processed to obtain the target information, wherein the output information includes information of K prediction spatial filters.

[0188] In some embodiments, when the size of the prediction spatial filter set configured by the network device is smaller than the size of the prediction spatial filter set supported by the first model, the information of the K target spatial filters is determined based on the information of the K prediction spatial filters output by the first model and the first mapping relationship, wherein the first mapping relationship is the mapping relationship between the spatial filters in the prediction spatial filter set configured by the network device and the spatial filters in the prediction spatial filter set supported by the first model.

[0189] In some embodiments, the first mapping relationship may be predefined or configured by the network device.

[0190] If the predicted spatial filter set configured by the network device includes N spatial filters, and the predicted spatial filter set supported by the first model includes M spatial filters, where N is less than M, in some implementations, the M spatial filters in the predicted spatial filter set supported by the first model can be divided into N groups, each group of spatial filters corresponding to a spatial filter in the predicted spatial filter set configured by the network device. If the spatial filter predicted by the first model belongs to group X in the N groups, then the spatial filter corresponding to group X in the predicted spatial filter set configured by the network device is the target spatial filter.

[0191] For example, as shown in Figure 16, the predicted spatial filter set configured by the network device includes 32 beams or beam pairs, and the predicted spatial filter set supported by the first model includes 64 beams or beam pairs. The 64 beams or beams can be grouped, and each group includes 2 beams or beam pairs, where beam #1 or beam pair #1 and beam #2 or beam pair #2 correspond to a beam or beam pair in the predicted spatial filter set configured by the network device. If the optimal beam or beam pair predicted by the first model is beam #2 or beam pair #2, then the beam or beam pair corresponding to the group to which beam #2 or beam pair #2 belongs in the predicted spatial filter set configured by the network device is the target beam or beam pair.

[0192] In other embodiments, when the size of the prediction spatial filter set configured by the network device is larger than the size of the prediction spatial filter set supported by the first model, information of X prediction spatial filters is determined based on information of K prediction spatial filters predicted by the first model and a second mapping relationship, wherein the second mapping relationship is a mapping relationship between spatial filters in the prediction spatial filter set configured by the network device and spatial filters in the prediction spatial filter set supported by the first model, and X is greater than K.

[0193] The information of the K target spatial filters is determined from the information of the X prediction spatial filters.

[0194] For example, K pieces of information on X prediction spatial filters are randomly selected as information on K target spatial filters.

[0195] In some embodiments, the second mapping relationship may be predefined or configured by the network device.

[0196] If the predicted spatial filter set configured by the network device includes N spatial filters, and the predicted spatial filter set supported by the first model includes M spatial filters, where N is greater than M, in some implementations, the N spatial filters in the predicted spatial filter set configured by the network device can be divided into M groups, each group of spatial filters corresponding to a spatial filter in the predicted spatial filter set supported by the first model. If the spatial filter predicted by the first model includes spatial filter #X, and the spatial filter #X corresponds to group Z in the M groups, the terminal device can select a spatial filter in group Z as the target spatial filter.

[0197] For example, as shown in Figure 17, the predicted spatial filter set supported by the first model includes 32 beams or beam pairs, and the predicted spatial filter set configured by the network device includes 64 beams or beam pairs. The 64 beams or beams can be divided into 32 groups, each group including 2 beams or beam pairs. If the optimal beam or beam pair predicted by the first model is beam #2 or beam pair #2, further, the terminal device can select a beam or beam pair from the group corresponding to the beam #2 or beam pair #2 in the 32 groups as the target beam or beam pair.

[0198] In some embodiments of the present application, the method 200 further includes:

[0199] The terminal device sends first reporting information to the network device, where the first reporting information is used to indicate information about the K target spatial filters or information about the K transmit spatial filters corresponding to the K target spatial filters.

[0200] Case 1: The K target spatial filters are K spatial filter pairs, that is, the first model is used to predict the optimal spatial filter pair.

[0201] In this case, the first reporting information is used to indicate information of the K spatial filter pairs or information of the transmit spatial filters in the K spatial filter pairs.

[0202] For example, K target spatial filters are K beam pairs, and the first reporting information can be used to indicate information of the K beam pairs, or can also be used to indicate information of the transmit beams in the K beam pairs.

[0203] Method 1: Report the information of the spatial filter pair.

[0204] In some embodiments, the first reporting information includes identification information of the K spatial filter pairs and measurement results of the K spatial filter pairs.

[0205] For example, the K target spatial filters are K beam pairs, and the first reporting information includes the indexes of the K beam pairs and the measurement results of the K beam pairs.

[0206] As a specific example, if Set A contains 256 beam pairs, each beam has an index ranging from 0 to 255, with a length of 8 bits. Then the index of the best K beam pairs needs to be at least 8*K bits long.

[0207] Optionally, in the first reporting information, information of the K spatial filter pairs is arranged in descending order of measurement results.

[0208] In some embodiments, the measurement results of the K spatial filter pairs may be indicated using reference measurement results and differential measurement results. For example, the absolute value of the measurement result of one spatial filter pair may be reported, and the measurement results of the other spatial filter pairs may be indicated using differential values ​​relative to the absolute value. Optionally, the reference measurement result may be the measurement result with the highest measurement result.

[0209] Table 1 illustrates the reporting format for a terminal device reporting four beam pairs (i.e., K = 4) and their corresponding measurement results. Tx-Rx beam pair #1 represents the index of the reported beam pair, where n = 1, 2, 3, or 4. RSRP #1 represents the absolute value of the L1-RSRP corresponding to Tx-Rx beam pair #1, Differential RSRP #2 represents the difference between the L1-RSRP corresponding to Tx-Rx beam pair #2 and RSRP #1, Differential RSRP #3 represents the difference between the L1-RSRP corresponding to Tx-Rx beam pair #3 and RSRP #1, and Differential RSRP #4 represents the difference between the L1-RSRP corresponding to Tx-Rx beam pair #4 and RSRP #1.

[0210] It should be understood that the embodiments of the present application do not limit the specific reporting method of the terminal device for reporting the measurement results. For example, the terminal device can also directly report the absolute value of the measurement results of each of the K beam pairs. The present application is not limited to this.

[0211] Table 1

[0212]

[0213] Method 2: reporting the information of the transmit spatial filter in the spatial filter pair.

[0214] In some embodiments, the first reporting information includes identification information of K transmit spatial filters and measurement results of K spatial filter pairs.

[0215] For example, K spatial filter pairs are K beam pairs, and the first reporting information includes the index of the transmit beam in the K beam pairs and the measurement results of the K beam pairs. Since the network device does not need to know the information of the receive beam on the terminal device side, in this implementation, the terminal device can only report the information of the transmit beam, which is beneficial to reducing the reporting overhead of the terminal device. If the terminal device side knows the receive beam corresponding to the reported transmit beam, the terminal device can store the receive beam information in the beam pair. When the network device indicates a transmit beam in the reported transmit beam, the corresponding receive beam can be used to receive the signal.

[0216] Continuing with the previous example, if Set A contains 256 beam pairs, including 64 transmit beams, the transmit beam index ranges from 0 to 63 and is 6 bits long. Therefore, reporting the transmit beam index of the optimal K beam pairs requires at least 6*K bits.

[0217] Optionally, in this method 2, the information of the K spatial filter pairs can also be arranged in descending order according to the measurement results. The difference is that the beam pair index in the reporting format is replaced by the index of the transmitting beam in the beam pair.

[0218] Case 2: The K target spatial filters are K transmit spatial filters, that is, the first model is used to predict the optimal transmit spatial filter.

[0219] In this case, the first reporting information includes identification information of the K transmit spatial filters and measurement results of the K transmit spatial filters.

[0220] For example, the first reporting information includes the indexes of the K transmit beams and the measurement results of the K transmit beams.

[0221] Optionally, in the first reporting information, information of the K transmit spatial filters is arranged in descending order of measurement results. In this case, the reporting format of the first reporting information is similar to the reporting format of the first reporting information in Case 1, except that the beam pair index in the reporting format is replaced by the transmit beam index. For the sake of brevity, this is not further described here.

[0222] Case 3: The K target spatial filters are K receiving spatial filters, that is, the first model is used to predict the optimal receiving spatial filter.

[0223] Since the network device does not need to know the receiving beam information on the terminal device side, the terminal device may not report in this case.

[0224] In some embodiments of the present application, the method 200 further includes:

[0225] The terminal device receives second indication information sent by the network device, where the second indication information is used to indicate at least one target spatial filter among the K target spatial filters or at least one transmit spatial filter corresponding to the at least one target spatial filter.

[0226] In some embodiments, if the first reported information includes information of K spatial filter pairs, the second indication information is used to indicate the target spatial filter pair among the K spatial filter pairs, or the second indication information is used to indicate the transmission spatial filter among the target spatial filter pair, wherein the target spatial filter pair includes one or more spatial filter pairs among the K spatial filter pairs.

[0227] For example, the first reporting information includes information of K beam pairs, and the second indication information is used to indicate a target beam pair among the K beam pairs, or to indicate a transmit beam among the target beam pairs. The target beam pair includes one or more beam pairs among the K beam pairs.

[0228] In some other embodiments, if the first reporting information includes information of K transmit spatial filters, the second indication information is used to indicate one or more transmit spatial filters among the K transmit spatial filters.

[0229] For example, the first reporting information includes information of K transmit beams, and the second indication information is used to indicate a target transmit beam among the K transmit beams, wherein the target transmit beam includes one or more transmit beams among the K transmit beams.

[0230] Optionally, if the network device indicates a transmit beam, the transmit beam may be indicated by indicating a TCI state.

[0231] For example, the second indication information is used to indicate at least one transmission configuration indication TCI state, and the at least one TCI state corresponds to at least one transmit spatial filter, and the at least one transmit spatial filter is a transmit spatial filter selected by the network device, or a transmit spatial filter in a spatial filter pair selected by the network device.

[0232] Optionally, in some embodiments of the present application, the network device may also perform a secondary beam scan after receiving the first reporting information from the terminal device to determine the performance of the K target spatial filters reported by the terminal device.

[0233] For example, the network device may trigger a beam scanning process including the K target spatial filters, the terminal device may measure the K target spatial filters, and further feed back the measurement results of the K target spatial filters to the network device.

[0234] Optionally, the network device may select a spatial filter based on the measurement results of the K target spatial filters obtained by the secondary scanning, and further instruct the network device to select the spatial filter through second indication information.

[0235] That is, the spatial filter indicated by the second indication information may be selected by the network device according to the first reporting information, or may be selected according to the measurement result of the secondary scan.

[0236] The following describes the specific implementation process of spatial filter prediction by a terminal device when the model for spatial filter prediction is deployed on the terminal device side, in conjunction with Figure 18. As shown in Figure 18, the process may include at least some of the following steps:

[0237] S201: The terminal device sends first capability information to the network device.

[0238] Among them, the specific implementation of the first capability information refers to the relevant description of the previous embodiment and will not be repeated here.

[0239] S202: The network device sends first configuration information to the terminal device.

[0240] The first configuration information is used to configure the prediction spatial filter set and / or the measurement spatial filter set.

[0241] In some embodiments, the first configuration information may be used to configure a prediction spatial filter set and a measurement spatial filter set.

[0242] In other embodiments, the first configuration information is used to indicate multiple prediction spatial filter sets and multiple measurement spatial filter sets, or multiple prediction spatial filter sets and one measurement spatial filter set, or one prediction spatial filter set and multiple measurement spatial filter sets.

[0243] Optionally, when the network device configures multiple prediction spatial filter sets and / or multiple measurement spatial filter sets for the terminal device, the network device may indicate a target prediction spatial filter set among the multiple prediction spatial filter sets and / or a target measurement spatial filter set among the multiple measurement spatial filter sets. For the specific implementation, refer to the relevant description of the first indication information in the previous text, which will not be repeated here for the sake of brevity.

[0244] S203: The terminal device performs measurement based on the measurement space filter set to obtain a first data set.

[0245] For example, the terminal device measures all spatial filters in the measurement spatial filter set to obtain a first data set.

[0246] S204: Determine target information according to the first data set and the first model.

[0247] Optionally, in S204, the terminal device may further pre-process the first data set. For specific implementation, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0248] Optionally, in S204, the terminal device may further perform post-processing on the output information of the first model. For specific implementation, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0249] S205: The terminal device sends first reporting information to the network device, which is used to report the information of the predicted spatial filter.

[0250] Among them, the specific implementation of the first reporting information refers to the relevant description of the previous embodiment and will not be repeated here.

[0251] S206: The network device sends second indication information to the terminal device, where the second indication information is used to indicate the spatial filter selected by the network device.

[0252] The specific implementation of the second indication information refers to the relevant description of the previous embodiment and will not be repeated here.

[0253] The following describes the specific implementation of three prediction scenarios in combination with Examples 1 to 3.

[0254] Example 1: Prediction of spatial filter pairs, or in other words, prediction of beam pairs. The purpose of beam pair prediction is the same as that of the P1 process, which is to find a suitable beam pair during the joint beam scanning process of the terminal device and the network device.

[0255] Specifically, the method may include at least some of the following steps:

[0256] Step 1: The terminal device sends first capability information to the network device.

[0257] Optionally, the first capability information is used to indicate information related to beams or beam pairs supported by the terminal device, or information related to beams or beam pairs related to the first model. For specific implementation, please refer to the relevant description of the aforementioned embodiment.

[0258] As an example, the first capability information is used to indicate a prediction beam pair set and a measurement beam pair set.

[0259] Step 2: The network device sends first configuration information to the terminal device.

[0260] The first configuration information is used to configure the prediction beam pair set and the measurement beam pair set.

[0261] In some embodiments, the first configuration information may be used to configure a set of prediction beam pair sets and measurement beam pair sets.

[0262] In some other embodiments, the first configuration information is used to indicate a combination of multiple prediction beam pair sets and measurement beam pair sets.

[0263] Optionally, when the network device configures a plurality of combinations of prediction beam pair sets and measurement beam pair sets for the terminal device, the network device may indicate a target combination among the plurality of combinations of prediction beam pair sets and measurement beam pair sets.

[0264] Step 3: The terminal device measures the set based on the measurement beam to obtain a first data set.

[0265] For example, the terminal device measures all beam pairs in the measurement beam pair set to obtain a first data set.

[0266] Optionally, the first data set may include measurement results of all beam pairs in the measurement beam pair set.

[0267] Step 4: Determine target information based on the first data set and the first model.

[0268] Optionally, in step 4, when the dimension of the first data set is different from the input dimension supported by the first model, the terminal device may further preprocess the first data set. For specific implementation, please refer to the relevant description of the previous embodiment and will not be repeated here.

[0269] Optionally, in step 4, when the dimension of the prediction beam pair set configured by the network device is different from the dimension of the prediction beam pair set supported by the first model, the terminal device can also post-process the output information of the first model. For the specific implementation, please refer to the relevant description of the previous embodiment and will not be repeated here.

[0270] Step 5: The terminal device sends first reporting information to the network device to report the information of the predicted beam pair.

[0271] For example, the first reporting information may include identification information of the predicted K beam pairs and measurement results of the K beam pairs. Optionally, the information of the K beam pairs may be arranged in descending order of measurement results.

[0272] For another example, the first reporting information may include identification information of the transmit beams in the predicted K beam pairs and measurement results of the K beam pairs, wherein the measurement results of the K beam pairs are arranged in descending order.

[0273] Step 6: The network device sends second indication information to the terminal device, where the second indication information is used to indicate the beam pair or transmission beam selected by the network device.

[0274] For example, when the first reporting information includes identification information of K beam pairs, the second indication information may indicate one or more beam pairs among the K beam pairs, for example, indicating identification information of the one or more beam pairs.

[0275] For another example, when the first reporting information includes identification information of K beam pairs, the second indication information may indicate the transmitting beam in a target beam pair among the K beam pairs, for example, indicating the identification information of the transmitting beam in the target beam pair.

[0277] Optionally, the network device may indicate the transmit beam via the TCI status.

[0278] Example 2: Transmit spatial filter prediction, or transmit beam prediction. Transmit beam prediction and the P2 process share the same purpose: finding a suitable transmit beam during transmit beam scanning. During beam scanning, the network device scans the transmit beam, while the terminal device uses a fixed receive beam.

[0279] Specifically, the method may include at least some of the following steps:

[0280] Step 1: The terminal device sends first capability information to the network device.

For specific implementation, please refer to the relevant description of the aforementioned embodiment.

[0282] As an example, the first capability information is used to indicate a predicted transmit beam set and a measured transmit beam set.

[0283] Step 2: The network device sends first configuration information to the terminal device.

[0284] The first configuration information is used to configure the predicted transmit beam set and the measured transmit beam set.

[0285] In some embodiments, the first configuration information may be used to configure a set of predicted transmit beam sets and a measurement transmit beam set.

[0286] In some other embodiments, the first configuration information is used to indicate a combination of multiple groups of predicted transmit beam sets and measured transmit beam sets.

[0287] Optionally, when the network device configures a plurality of combinations of predicted transmit beam sets and measured transmit beam sets for the terminal device, the network device may indicate a target combination among the plurality of combinations of predicted transmit beam sets and measured transmit beam sets.

[0288] Step 3: The terminal device performs measurement based on the measurement transmit beam set to obtain a first data set.

[0289] For example, the terminal device measures all transmit beams in the measurement transmit beam set (in this case, the terminal device uses a fixed receive beam) to obtain a first data set.

[0290] Optionally, the first data set may include measurement results of all transmit beams in the transmit beam set, wherein the measurement results of the transmit beams may be considered as measurement results of a beam pair consisting of the transmit beam and the receive beam used by the terminal device.

[0291] Step 4: Determine target information based on the first data set and the first model.

[0292] Optionally, in step 4, when the dimension of the first data set is different from the input dimension supported by the first model, the terminal device may further preprocess the first data set.

[0293] Optionally, in step 4, when the dimension of the predicted transmit beam set configured by the network device is different from the dimension of the predicted transmit beam set supported by the first model, the terminal device may also post-process the output information of the first model. For the specific implementation, please refer to the relevant description of the previous embodiment and will not be repeated here.

[0294] Step 5: The terminal device sends first reporting information to the network device to report the information of the predicted transmission beam.

[0295] For example, the first reporting information may include identification information of the predicted K transmit beams and measurement results of the K transmit beams. Optionally, the information of the K transmit beams may be arranged in descending order of measurement results.

[0296] Step 6: The network device sends second indication information to the terminal device, where the second indication information is used to indicate the transmission beam selected by the network device.

[0297] For example, the first reporting information includes identification information of K transmit beams, and the second indication information may indicate a target transmit beam among the K transmit beams.

[0298] Optionally, the network device may indicate the transmit beam via the TCI status.

[0299] Example 3: Receive spatial filter prediction, or receive beam prediction. The purpose of receive beam prediction and the P3 process is the same: to find a suitable receive beam during receive beam scanning. During P3 beam scanning, the network device fixes the transmit beam, while the terminal device performs receive beam scanning.

[0300] Specifically, the method may include at least some of the following steps:

[0301] Step 1: The terminal device sends first capability information to the network device.

[0302] Optionally, the first capability information is used to indicate information related to beams or beam pairs supported by the terminal device, or information related to beams or beam pairs related to the first model. For specific implementation, please refer to the relevant description of the aforementioned embodiment.

[0303] As an example, the first capability information is used to indicate a predicted reception beam set and a measured reception beam set.

[0304] Step 2: The network device sends first configuration information to the terminal device.

[0305] The first configuration information is used to configure the predicted receiving beam set and the measured receiving beam set.

[0306] In some embodiments, the first configuration information may be used to configure a set of predicted receive beam sets and a set of measured receive beam sets.

[0307] In some other embodiments, the first configuration information is used to indicate a combination of multiple groups of predicted receiving beam sets and measurement receiving beam sets.

[0308] Optionally, when the network device configures a plurality of combinations of predicted reception beam sets and measured reception beam sets for the terminal device, the network device may indicate a target combination among the plurality of combinations of predicted reception beam sets and measured reception beam sets.

[0309] Step 3: The terminal device performs measurement based on the measurement receiving beam set to obtain a first data set.

[0310] For example, the terminal device measures all receiving beams in the measurement receiving beam set (in this case, the network device uses a fixed transmitting beam) to obtain a first data set.

[0311] Optionally, the first data set may include measurement results of all receiving beams in the receiving beam set, wherein the measurement results of the receiving beams may be considered as measurement results of a beam pair consisting of the receiving beam and a transmitting beam used by the network device.

[0312] Step 4: Determine target information based on the first data set and the first model.

[0313] Optionally, in step 4, when the dimension of the first data set is different from the input dimension supported by the first model, the terminal device may further preprocess the first data set. For specific implementation, please refer to the relevant description of the previous embodiment and will not be repeated here.

[0314] Optionally, in step 4, when the dimension of the predicted receiving beam set configured by the network device is different from the dimension of the predicted receiving beam set supported by the first model, the terminal device can also post-process the output information of the first model. For the specific implementation, please refer to the relevant description of the previous embodiment and will not be repeated here.

[0315] In this embodiment 3, since the network device does not need to know the receiving beam on the terminal device side, the terminal device does not need to report the receiving beam.

[0316] On the network device side, because the network device uses a fixed transmit beam for scanning, the network device does not need to indicate its corresponding Rx beam.

[0317] In summary, in an embodiment of the present application, the terminal device can predict the target spatial filter based on the model, so that the network device and the terminal device do not need to scan all spatial filters in the predicted spatial filter set, which is conducive to reducing scanning overhead and delay.

[0318] In some scenarios, the terminal device may send first capability information to the network device to report beam-related capability information of the terminal device.

[0319] In some embodiments, the network device may send first configuration information to the terminal device, for configuring the prediction spatial filter set and / or the measurement spatial filter set.

[0320] In some embodiments, the terminal device may report information of the target spatial filter based on model prediction to the network device.

[0321] Furthermore, the network device may inform the terminal device of the spatial filter selected by the network device, or the spatial filter actually used, based on the report from the terminal device.

[0361] In some embodiments of the present application, the network device may further pre-process the input information of the second model. For specific implementation, refer to the relevant description in method 200, which will not be repeated here for the sake of brevity.

[0362] For example, when the dimension of the second data set is inconsistent with the input dimension supported by the second model, the second data set is preprocessed to make the dimension of the input information of the second model consistent with the input dimension supported by the second model.

[0363] That is, the input information of the second model may be the second data set, or may be data obtained by processing the second data set.

[0364] In some embodiments of the present application, the S320 includes:

[0365] When the number of pieces of information on the multiple measurement space filters included in the second data set is different from the input dimension of the second model, processing the pieces of information on the multiple measurement space filters to obtain target input information, wherein the number of pieces of information on the measurement space filters included in the target input information is the same as the input dimension of the second model;

[0366] The target input information is processed by the second model to obtain the target information.

[0367] For example, when the amount of information on multiple measurement space filters included in the second data set is smaller than the input dimension of the second model, upsampling processing is performed on the information on the multiple measurement space filters to obtain the target input information.

[0368] For another example, when the amount of information on multiple measurement space filters included in the second data set is greater than the input dimension of the second model, downsampling processing is performed on the information on the multiple measurement space filters to obtain the target input information.

[0369] In some embodiments of the present application, the network device may further perform post-processing on the output information of the second model. Specific implementations are described in the related description of method 200, which will not be repeated here for the sake of brevity.

[0370] For example, when the size of the prediction spatial filter set configured by the network device is inconsistent with the size of the prediction spatial filter set supported by the second model, the network device can post-process the output information of the second model to make the accuracy of the output information of the second model the same as the accuracy of the Set A set configured by the network device.

[0371] That is, the target information may be the output information of the second model, or may be data obtained by processing the output information of the second model.

[0372] In some embodiments of the present application, the S320 includes:

[0373] When the size of the prediction spatial filter set configured by the network device is different from the size of the prediction spatial filter set supported by the second model, the output information of the second model is processed to obtain the target information, wherein the output information includes information of Q prediction spatial filters.

[0374] For example, when the size of the prediction spatial filter set configured by the network device is smaller than the size of the prediction spatial filter set supported by the second model, the information of the Q target spatial filters is determined based on the information of the Q prediction spatial filters and a first mapping relationship, wherein the first mapping relationship is a mapping relationship between the spatial filters in the prediction spatial filter set configured by the network device and the spatial filters in the prediction spatial filter set supported by the second model.

[0375] For another example, when the size of the prediction spatial filter set configured by the network device is larger than the size of the prediction spatial filter set supported by the second model, information of Y prediction spatial filters is determined based on the information of the Q prediction spatial filters and a second mapping relationship, wherein the second mapping relationship is a mapping relationship between spatial filters in the prediction spatial filter set configured by the network device and spatial filters in the prediction spatial filter set supported by the second model, wherein Y is greater than Q;

[0376] The information of the Q target spatial filters is determined from the information of the Y prediction spatial filters.

[0377] For example, Q pieces of information on Y prediction spatial filters are randomly selected as information on Q target spatial filters.

[0378] Optionally, in some embodiments of the present application, after predicting the Q target spatial filters, the network device may also perform a secondary beam scan to determine the performance of the predicted Q target spatial filters.

[0379] For example, the network device may trigger a beam scanning process including the Q target spatial filters, the terminal device measures the Q target spatial filters, and further feeds back the measurement results of the Q target spatial filters to the network device.

[0380] Optionally, the network device may select a spatial filter based on the measurement results of the Q target spatial filters obtained by the secondary scanning, and further instruct the network device to select the spatial filter through third indication information.

[0381] That is, the spatial filter indicated by the third indication information may be predicted by the network device according to the second model, or may be selected according to the measurement result of the secondary scan.

[0382] In some embodiments of the present application, the method 300 further includes:

[0383] The network device sends third indication information to the terminal device, where the third indication information is used to indicate at least one target spatial filter among the Q target spatial filters or at least one target transmit spatial filter corresponding to the at least one target spatial filter.

[0384] Case 1: The Q target spatial filters are Q spatial filter pairs.

[0385] In some embodiments, the third indication information is used to indicate one or more spatial filter pairs among the Q spatial filter pairs.

[0386] In some other embodiments, the third indication information is used to indicate a transmit spatial filter in a target spatial filter pair, wherein the target spatial filter pair includes one or more spatial filter pairs among the Q spatial filter pairs.

[0387] Optionally, the third indication information is used to indicate at least one TCI state, and the at least one TCI state corresponds to the transmit spatial filter in the target spatial filter pair.

[0388] For example, the Q target spatial filters are Q beam pairs, and the third indication information is used to indicate L beam pairs among the Q beam pairs, or to indicate L transmit beams among the L beam pairs, where L is a positive integer.

[0389] Optionally, the third indication information is used to indicate L TCI states, where the L TCI states correspond to L transmit beams.

[0390] Optionally, when the network device configures Set A for the terminal device, the network device may indicate a target beam pair among the Q beam pairs. In this way, the terminal device may determine a corresponding receiving beam according to Set A.

[0391] Optionally, when the network device does not configure Set A for the terminal device, the network device may indicate the transmit beam in the target beam pair, and further trigger a secondary scanning process to enable the terminal device to find a suitable receive beam.

[0392] Case 2: The Q target spatial filters include Q transmit spatial filters.

[0393] In this case, the third indication information is used to indicate one or more transmit spatial filters among the Q transmit spatial filters.

[0394] For example, the Q target spatial filters are Q transmit beams, and the third indication information is used to indicate L transmit beams among the Q transmit beams, where L is a positive integer.

[0395] Optionally, the third indication information is used to indicate L TCI states, where the L TCI states correspond to L transmit beams.

[0396] Case 3: Q target spatial filters include Q receive spatial filters.

[0397] In this case, the third indication information is used to indicate one or more receiving spatial filters among the Q receiving spatial filters.

[0398] For example, the Q target spatial filters are Q receiving beams, and the third indication information is used to indicate L receiving beams among the Q receiving beams, where L is a positive integer.
