[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202410160342.3 and application date of February 4, 2024, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application in its entirety. Technical Field

[0003] The present application relates to the field of wireless communication technologies, and in particular to a communication method, apparatus, storage medium, program product, and communication equipment. Background Art

[0004] Within the design framework of 5G (5th Generation Mobile Communication Technology), artificial intelligence (AI) can be applied to multiple areas, including channel state information (CSI) feedback, beam management, and positioning, achieving corresponding gains and demonstrating promising application prospects. A typical use case for AI in beam management is spatial beam prediction. AI-based spatial beam prediction measures the Layer 1 Reference Signal Received Power (L1-RSRP) of a subset of beam pairs (referred to as setB) to predict the L1-RSRP for all beam pairs (setA) and select the optimal beam, reducing terminal beam measurement overhead.

[0005] In related technologies, CSI resource configuration can only configure one period of the semi-persistent resource set. However, the semi-persistent resource set needs to be activated twice in the entire process of training, inference, and monitoring of the AI ​​model used for spatial beam prediction. That is, after activation, it is used for data collection in the training and monitoring stages respectively. The corresponding periods of all beam pair sets setA are different, the reporting amounts are different, and the uplink resources used may also be different. The current CSI-related configuration cannot achieve this configuration. Summary of the Invention

[0043] Before describing the communication method according to the embodiment of the present application, a brief description of beam prediction in the related art is first given.

[0044] Taking the example of a base station corresponding to 64 transmit beams and a terminal corresponding to 4 receive beams (Rx beams), Figure 1 is a schematic diagram of beam tracking in the related art. As shown in Figure 1, the base station can configure a periodic resource set with 8 CSI-RS reference signals (i.e., 8RS in Figure 1). The beam tracking frequency or reference signal period is 20 milliseconds (ms). Within 4 periods, the terminal uses 4 receive beams to receive 8 transmit beams, and the L1-RSRP corresponding to 32 beam pairs can be obtained. The terminal reports the CSI-RS resource indication (CRI) and L1-RSRP of the 4 beam pairs with the largest L1-RSRP, and the base station indicates one of the reference signals to communicate with the terminal.

[0045] The implementation method for spatial beam prediction based on an AI model is to first train it based on a large dataset, such as a dataset containing millions of sample data, each sample data containing the RSRP of all beam pairs at a certain moment. Figure 2 is a schematic diagram of the principle of spatial beam prediction based on an AI model in the related art. As shown in Figure 2, for beam pair prediction, the RSRP of a small number of beam pairs (referred to as setB) can be used as the input of the AI ​​model (usually a neural network) during training, and the RSRP of all beam pairs (referred to as setA) can be used as the labels output by the AI ​​model. The parameters within the AI ​​model are continuously updated using the gradient descent algorithm until the error (e.g., normalized mean square error) between the AI ​​model output and the labels is less than a threshold. The model is then considered to have converged and has good predictive ability. For transmit beam prediction, according to a certain receive beam hypothesis, the RSRP of a small number of transmit beams can be used as the input of the AI ​​model during training, and the RSRP of all transmit beams can be used as the labels output by the AI ​​model. The parameters within the AI ​​model are continuously updated using the gradient descent algorithm until the error between the AI ​​model output and the labels is less than a threshold.

[0046] For spatial beam pair prediction based on AI models, data can be collected first for AI model training. Figure 3 is a schematic diagram of the training phase and inference phase of spatial beam pair prediction based on AI models in related technologies. As shown in Figure 3, the base station needs to scan the set (setA) of all 256 (64×4) beam pairs in a short period of time to prevent the RSRP of different beam pairs from changing over time. The period of setA can be very long (for example, tens of minutes, hours, etc.). Among them, there is no need to report measurement results during terminal side training, but the terminal needs to report measurement results during network side training.

[0047] After model training, when the terminal performs inference, as shown in Figure 3, the base station configures 32 (8×4) CSI-RS reference signals (setB) with an 80ms period. At each moment, the terminal measures the L1-RSRP of 32 beam pairs. The terminal uses these 32 measured L1-RSRPs as input to the AI ​​model, which then predicts the L1-RSRP of 256 beam pairs. The terminal then reports the CRI and L1-RSRP of the K beam pairs with the best RSRP from the setA of all beam pairs. Based on the predicted RSRP values ​​and beam pair load, the base station can instruct a particular beam pair to communicate with the terminal. If, after a period of inference, the terminal experiences events such as BFR or NACK feedback exceeding a threshold, data collection is required to monitor model performance. The terminal can scan all beam pairs in setA over a longer period (e.g., several seconds or minutes). The terminal or network device can compare the error between the optimal beam predicted from all beam pairs based on the 32 reference signals (setB) and the actual optimal beam from all beam pairs. When a model monitoring indicator, such as beam prediction accuracy, is less than a threshold, the terminal or network device can trigger a model update / switch / fallback to the traditional beam selection mode.

[0048] In related technologies, CSI resource configuration can only configure one cycle of the semi-persistent resource set. However, the semi-persistent resource set needs to be activated twice in the entire training, inference, and monitoring process of the AI ​​model used for spatial beam prediction. That is, after activation, it is used for data collection in the training and monitoring stages respectively. After the two activations, the cycle of setA is different, the reported measurement quantity is different, and the uplink resources used are also different. The current CSI-related configuration cannot achieve this configuration.

[0049] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of the present application, not all of them.

The steps can be selectively rearranged as needed, or the steps in the embodiments can be deleted, or the steps in the embodiments can be added. The step descriptions in the embodiments of the present application are only optional sequence combinations and do not represent all step sequence combinations in the embodiments of the present application. The order of the steps in the embodiments cannot be considered as a limitation of the present application.

[0053] In each embodiment of the present application, the network device may be a network-side device with wireless transceiver functions or a chip or chip system provided in the network-side device. The network device is, for example, an access network device, which may be referred to as a base station (BS), for example, a base transceiver station (BTS), a base station controller (BSC), a node B, a radio network controller (RNC), an evolved base station (eNB), an evolved nodeB, a next generation base station (gNB), a transmission reception point (TRP), and the like.

[0054] In the various embodiments of the present application, a terminal may also be referred to as a terminal device, user equipment (UE), mobile station, subscriber unit, station, etc. The terminal may be a cellular phone, an in-vehicle wireless communication device, a personal digital assistant (PDA), a wireless modem, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, etc. With the development of wireless communication technology, any device that can access a wireless communication network, communicate with a wireless network, or communicate with other objects via a wireless network may be a terminal device in the embodiments of the present application, such as terminal devices and automobiles in intelligent transportation, household appliances in smart homes, power meter reading instruments, voltage monitoring instruments, environmental monitoring instruments in smart grids, video surveillance instruments in intelligent security networks, cash registers, etc. The terminal may be static or mobile.

[0055] The present application provides a communication method. FIG4 is a flow chart of the communication method according to the present application. As shown in FIG4 , the method includes:

[0056] Step 101: A network device sends first information to a terminal, where the first information includes two groups of first configuration information corresponding to a reference signal resource set; the first configuration information is used to configure a first period and a first time offset information of each reference signal resource in the reference signal resource set.

[0057] In this embodiment, the first period of each reference signal resource in the reference signal resource set configured by each of the two groups of first configuration information is different, and / or the first time offset information of each reference signal resource set in the reference signal resource set configured by each of the two groups of first configuration information is different. It can be understood that this embodiment can configure two periods and time offset information for each reference signal resource in the reference signal resource set, which can be used for different data collection stages of the model respectively. The first model can be used for spatial beam prediction, such as the aforementioned AI model, and the data collection stage includes, for example, a data collection stage for model training, a data collection stage for model monitoring, etc.

[0058] As an example, the two sets of first configuration information may include a first set of first configuration information and a second set of first configuration information, wherein the first period configured in the first set of first configuration information is greater than the first period configured in the second set of first configuration information. Exemplarily, the first set of first configuration information may be used in the data collection phase of model training, and the second set of first configuration information may be used in the data collection phase of model monitoring.

[0059] In some embodiments, the reference signal resource is a CSI-RS reference signal, the reference signal resource set may be a CSI-RS resource set, and the network device may configure the two sets of first configuration information through high-layer radio resource control (RRC) signaling. Exemplarily, the following information element (IE, Information Element) may be added to the parameter NZP-CSI-RS-Resource:

[0060] The parameter NZP-CSI-RS-Resource can be used to configure CSI-RS resources, and the parameters periodicityAndOffset1 and periodicityAndOffset2 can be used to configure two periodicities and time offset information, respectively. For example, a larger period and corresponding time offset information, and a smaller period and corresponding time offset information, respectively. The periodicOrSemiPersistent parameter is configured only when the RS is periodic or semi-persistent.

[0061] 3 , this embodiment can configure the reference signal resource set through the first information for different data collection stages corresponding to the training and monitoring processes of the spatial beam prediction model (such as the aforementioned model, AI model, etc.), wherein when collecting data for training, the period of the configurable resource set setA is the first period corresponding to the first group of first configuration information. At this time, the period of setA can be very long (such as tens of minutes, hours, etc.); when performing model monitoring, the period of the configurable resource set setA is the first period corresponding to the second group of first configuration information. At this time, the period of setA is slightly smaller (such as seconds, minutes, etc.). In this way, the configuration problems of different data collection stages and semi-continuous resource sets in model training and model monitoring in beam prediction based on AI models can be solved.

[0062] The communication method of the embodiment of the present application can configure two sets of first configuration information corresponding to the reference signal resource set through the first information, that is, configure two sets of different period and time offset information for the reference signal resource set, and can adapt to the different requirements for the reference signal resource set period in the training and monitoring stages of the model used for spatial beam prediction.

[0063] In an optional embodiment of the present application, the method may further include: the network device sends a first MAC CE to the terminal, where the first MAC CE is used to indicate at least one of the following information: activating or deactivating the reference signal resource set; configuring the activated reference signal resource using the first group of first configuration information or the second group of first configuration information; activating at least one reference signal resource in the reference signal resource set.

[0064] As an optional implementation, the first MAC CE may include a first field, and the value of the first field includes a first value and a second value; wherein, the first value is used to indicate that the activated reference signal resources are configured using the first group of first configuration information; wherein, the first period included in the first group of first configuration information is greater than the first period included in the second group of first configuration information; the second value is used to indicate that the activated reference signal resources are configured using the second group of first configuration information; and the first MAC CE also includes indication information of the at least one reference signal resource.

[0065] In this embodiment, when the value of the first field is the first value, it can represent the use of the first group of first configuration information to configure the activated reference signal resources, for example, the use of a larger first period to configure the reference signal resources, which can be used for data collection in the training phase of the spatial beam prediction model; when the value of the first field is the second value, it can represent the use of the second group of first configuration information to configure the activated reference signal resources, for example, the use of a smaller first period to configure the reference signal resources, which can be used for data collection in the monitoring phase of the spatial beam prediction model. At this time, the first MAC CE may also include indication information of at least one reference signal resource, that is, the first MAC CE may also indicate the activation of at least one reference signal resource in the reference signal resource set, so that when the semi-persistent resource set is activated for model monitoring, only a subset of the resource set can be activated to reduce terminal measurement overhead.

[0066] In some embodiments, the first MAC CE may further include a second field. When the second field takes a third value, it may indicate activation of the reference signal resource set, which may be used, for example, in the training and monitoring phases of a spatial beam prediction model. When the second field takes a fourth value, it may indicate deactivation of the reference signal resource set, which may be used, for example, in the inference or prediction phases of a spatial beam prediction model. It should be noted that, when the first MAC CE includes indication information of the at least one reference signal resource, the third value in this embodiment may also be used to indicate activation of the at least one reference signal resource.

[0067] In the related technology, for the PUCCH-based semi-persistent CSI reporting configuration, it can use periodic and semi-persistent CSI-RS resources and be activated or deactivated through MAC CE. Once the PUCCH-based semi-persistent CSI reporting configuration is activated, the terminal will report CSI according to the configured transmission period and time slot offset until deactivated; after deactivation, the terminal will no longer report CSI until reactivated.

[0068] 3 , this embodiment can configure the reference signal resource set through the first information and the first MAC CE for the measurement of all beam pair sets setA at different stages of the entire process of training, reasoning, and monitoring of the spatial beam prediction model. When collecting data for training, the resource set setA can be activated through the first MAC CE. The period of setA can be configured, for example, through the first group of first configuration information in this embodiment. The corresponding period can be very long (for example, tens of minutes, hours, etc.); when training is completed and reasoning begins, setA can be deactivated through the first MAC CE. SetA is not transmitted, but the reference signal identifier in setA can be used for reporting the K beam pairs with the best quality; when model monitoring is performed, the resource set setA can be activated through the first MAC CE. At this time, the period of setA can be configured through the second group of first configuration information in this embodiment. The corresponding period is slightly shorter (for example, seconds, minutes, etc.). In this way, the data collection phase corresponding to training and monitoring in beam prediction based on AI models, the configuration and reporting configuration of semi-persistent resource sets can be solved.

[0069] In some embodiments, the indication information of the at least one reference signal resource includes first index information and second index information, wherein the first index information represents the index information of the first reference signal resource in the at least one reference signal resource, and the second index information represents the index information of the last reference signal resource in the at least one reference signal resource; or, the indication information of the at least one reference signal resource includes bitmap information of the at least one reference signal resource in the reference signal resource set. In this embodiment, the at least one reference signal resource can be configured in the form of a starting reference signal sequence number and an ending reference signal sequence number, or can also be configured in the form of a bit corresponding to the reference signal. Therefore, this embodiment indicates the resource subset (i.e., at least one reference signal resource) of the activated reference signal resource set in the first MAC CE, and can only send beams in the resource subset during the model monitoring phase for spatial beam prediction, instead of all beams in setA in the related art, thereby reducing terminal measurement overhead.

[0070] FIG5 is a schematic diagram of the structure of a first MAC CE according to an embodiment of the present application. As shown in FIG5 , information about the period to be activated (i.e., the first field), the starting / ending reference signal sequence number of the resource set subset, or the reference signal bitmap information can be added to the semi-persistent resource set activation / deactivation MAC CE in the related art. A / D parameter values ​​of "1" indicate activation of the corresponding CSI-RS resource set, while values ​​of "0" indicate deactivation of the corresponding CSI-RS resource set. P parameter values ​​of "0" indicate configuration using the first period and first time offset information corresponding to the first set of first configuration information, such as the period and time offset information configured by the aforementioned parameter periodicityAndOffset1. P parameter values ​​of "1" indicate configuration using the first period and first time offset information corresponding to the second set of first configuration information, such as the period and time offset information configured by the aforementioned parameter periodicityAndOffset2. Start resource ID parameter indicates the starting ID of a resource subset in the CSI-RS resource set, and End resource ID parameter indicates the ending ID of a resource subset in the CSI-RS resource set.

[0071] The communication method of the embodiment of the present application can use a semi-continuous CSI reporting configuration to realize the measurement reporting of all beam pair sets (setA) at different stages in the entire process of training, reasoning and monitoring corresponding to the AI ​​model for spatial beam prediction, that is, when collecting data for training, the resource set setA can be activated through the first MAC CE, and the period of the setA can be configured with a larger period; when the training is completed and reasoning starts, the setA can be deactivated through the first MAC CE; when model monitoring is performed, the resource set setA can be activated through the first MAC CE, and the period of the setA can be configured with a smaller period. At the same time, it can also be indicated that only a subset of resources in the setA is activated for model monitoring, which reduces the terminal measurement overhead and can solve the data collection stage, configuration and reporting configuration of the semi-continuous resource set corresponding to training and monitoring in the beam prediction based on the AI ​​model.

[0072] Based on the foregoing embodiment, an embodiment of the present application further provides a communication method. In this embodiment, the method may further include: the network device sending second information to the terminal, the second information including at least a first group of second configuration information associated with the first group of first configuration information and a second group of second configuration information associated with the second group of first configuration information; wherein the second configuration information is used to configure a second period and second time offset information for the terminal to report measurement results of the reference signal resource set.

[0073] In this embodiment, the network device may further configure two groups of second configuration information, wherein the first group of second configuration information is associated with the first group of first configuration information, and the second group of second configuration information is associated with the second group of first configuration information. The two groups of second configuration information each configure a different second period for the terminal to report the measurement result of the reference signal resource set, and / or the two groups of second configuration information each configure a different second time offset information for the terminal to report the measurement result of the reference signal resource set. It can be understood that this embodiment may further configure two periods and / or two time offset information for the terminal to report the measurement of the reference signal resource set, which can be used respectively for different data collection stages of the spatial beam prediction model. The spatial beam prediction model is, for example, the aforementioned AI model for spatial beam prediction, and the data collection stage includes, for example, a data collection stage for model training, a data collection stage for model monitoring, and the like.

[0074] In some embodiments, the second information may further include reporting quantities corresponding to each of the two sets of second configuration information, and / or the second information may further include index information or configuration information of uplink transmission resources corresponding to each of the two sets of second configuration information. In this embodiment, the network device may further configure two different sets of reporting quantities and / or two different sets of uplink transmission resources, where the reporting quantities are reporting parameters or measurement quantities corresponding to when the terminal reports the measurement results of the reference signal resource set, and the uplink transmission resources are transmission resources used by the terminal when reporting the measurement results of the reference signal resource set.

[0075] Exemplarily, the uplink transmission resource is carried on PUCCH or PUSCH.

[0076] As an example, the second information may include a first reporting amount corresponding to the first group of second configuration information and a second reporting amount corresponding to the second group of second configuration information; wherein the first reporting amount includes at least one of the following: CRI and RSRP; CSI-RS resource set index and RSRP; CRI, receive beam index and RSRP; CSI-RS resource set index, receive beam index and RSRP; and / or, the second reporting amount includes at least one of the following: CRI and RSRP; CRI and RSRP of the reference signal with the highest RSRP; CRI of each of the top K reference signals with the highest RSRP; K is an integer greater than 1; CSI-RS resource set index and RSRP; CSI-RS resource set index and RSRP of the reference signal with the highest RSRP; CSI-RS resource set index of each of the top K reference signals with the highest RSRP; CRI, receive beam index and RSRP Beam index and RSRP; CRI, receive beam index, and RSRP of the reference signal with the highest RSRP; CRI and receive beam index of each of the top K reference signals with the highest RSRP; CSI-RS resource set index, receive beam index, and RSRP; CSI-RS resource set index, receive beam index, and RSRP of the reference signal with the highest RSRP; CSI-RS resource set index and receive beam index of each of the top K reference signals with the highest RSRP; RSRP difference between the predicted reference signal with the highest RSRP and the measured reference signal with the highest RSRP; a first parameter characterizing whether the predicted reference signal with the highest RSRP belongs to or does not belong to the top K measured reference signals with the highest RSRP; a second parameter characterizing whether the measured reference signal with the highest RSRP belongs to or does not belong to the predicted top K reference signals with the highest RSRP.

[0077] In this embodiment, if the first period corresponding to the first group of first configuration information is greater than the second period corresponding to the second group of first configuration information, the first group of second configuration information can be used for measurement reporting of reference signal resource sets with a larger period, such as data collection in the training phase of the spatial beam prediction model. When the terminal uses the second period and second time offset information corresponding to the first group of second configuration information for measurement reporting, the corresponding reporting amount is the first reporting amount, such as the terminal reporting CRI and RSRP, or the terminal reporting CSI-RS resource set index and RSRP, or the terminal reporting CRI, receiving beam index and RSRP, or the terminal reporting CSI-RS resource set index, receiving beam index and RSRP.

[0078] The second group of second configuration information can be used for measurement reporting of reference signal resource sets with a smaller period, such as data collection in the monitoring phase of the spatial beam prediction model. When the terminal uses the second period and second time offset information corresponding to the second group of second configuration information for measurement reporting, the corresponding reporting amount is the second reporting amount, for example, the terminal reports CRI and RSRP, or the terminal reports the CRI and RSRP of the reference signal with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or the terminal reports the K (K>1 and an integer) reference signals with the highest RSRP obtained by beam prediction using the spatial beam prediction model. The terminal reports the CRI of each reference signal, or the terminal reports the CSI-RS resource set index and RSRP, or the terminal reports the CSI-RS resource set index and RSRP of the reference signal with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or the terminal reports the CSI-RS resource set index of each of the K reference signals with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or the terminal reports the CRI, receive beam index and RSRP, or the terminal reports the CRI, receive beam index and RSRP of the reference signal with the highest RSRP obtained by beam prediction using the spatial beam prediction model. RSRP, or the terminal reports the CRI and receive beam index of the K reference signals with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or the terminal reports the CSI-RS resource set index, receive beam index and RSRP of the reference signal with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or the terminal reports the CSI-RS resource set index and receive beam index of the K reference signals with the highest RSRP obtained by beam prediction using the spatial beam prediction model, or Alternatively, the terminal reports an RSRP difference between a reference signal with a highest RSRP predicted by using a spatial beam prediction model and a reference signal with a highest RSRP actually measured, or the terminal reports a first parameter, where the first parameter characterizes whether the reference signal with the highest RSRP predicted by using the spatial beam prediction model belongs to or does not belong to the K reference signals with the highest RSRP actually measured, or the terminal reports a second parameter, where the second parameter characterizes whether the reference signal with the highest RSRP actually measured belongs to or does not belong to the K reference signals with the highest RSRP actually measured.

[0079] Exemplarily, the first parameter may take values ​​of a fifth value and a sixth value, wherein when the first parameter takes the fifth value, it may characterize that the reference signal with the highest RSRP obtained by using the spatial beam prediction model for prediction belongs to the K reference signals with the highest RSRP ranking actually obtained by measurement, and when the first parameter takes the sixth value, it may characterize that the reference signal with the highest RSRP obtained by using the spatial beam prediction model for prediction does not belong to the K reference signals with the highest RSRP ranking actually obtained by measurement; the second parameter may take values ​​of a seventh value and an eighth value, wherein when the second parameter takes the seventh value, it may characterize that the reference signal with the highest RSRP obtained by using the spatial beam prediction model for prediction belongs to the K reference signals with the highest RSRP ranking actually obtained by measurement, and when the second parameter takes the eighth value, it may characterize that the reference signal with the highest RSRP obtained by using the spatial beam prediction model for prediction does not belong to the K reference signals with the highest RSRP ranking actually obtained by measurement.

[0080] In some embodiments, the reference signal resource is a CSI-RS reference signal. The network device can configure the two sets of second configuration information and the corresponding reporting amount and uplink transmission resource association of the two sets of second configuration information through high-level RRC signaling, which can respectively correspond to different data collection stages in the training and monitoring process of the spatial beam prediction model. For example, the following IE can be added to the parameter CSI-ReportConfig:

[0081] Among them, the parameter CSI-ReportConfig can be used to configure the measurement reporting of CSI-RS resources, and the parameter reportSlotConfig can be used to configure the period and time offset information of the CSI-RS resource measurement reporting. In this embodiment, the parameters periodicityAndOffset3 and periodicityAndOffset4 may be included, which can be used to configure a larger reporting period and the corresponding time offset information, and to configure a smaller reporting period and the corresponding time offset information, respectively. semiPersistentOnPUCCH refers to semi-continuous reporting on PUCCH resources. The parameter pucch-CSI-ResourceList can be used to configure the PUCCH resources (i.e., uplink transmission resources) for CSI reporting, and specifically may include the index information or configuration information of the uplink transmission resources corresponding to the parameter periodicityAndOffset3, and the index information or configuration information of the uplink transmission resources corresponding to the parameter periodicityAndOffset4. The parameter reportQuantity can be used to configure the reporting quantity, which may include the first reporting quantity X corresponding to the parameter periodicityAndOffset3 (i.e., the first set of second configuration information) and the second reporting quantity Y corresponding to the parameter periodicityAndOffset4 (i.e., the second set of second configuration information). semiPersistentOnPUSCH refers to semi-persistent reporting on PUSCH resources.

[0082] Exemplarily, the first reporting amount X can be one of cri-RSRP, crsi-RSRP, cri-rbi-RSRP or crsi-rbi-RSRP, wherein the parameter cri-RSRP is used to indicate that the terminal reports CRI and RSRP, the parameter crsi-RSRP is used to indicate that the terminal reports the CSI-RS resource set index (CRSI, CSI-RS Resource Set Indicator) and RSRP, the parameter rbi-RSRP is used to indicate that the terminal reports CRI, receive beam index (RBI, CRI-Rx beam ID) and corresponding RSRP, and the parameter crsi-rbi-RSRP is used to indicate that the terminal reports the CSI-RS resource set indication, receive beam index and corresponding RSRP.

[0083] The second reporting amount Y can be, for example, one of cri-RSRP, top1cri-RSRP, topKcri, crsi-RSRP, top1crsi-RSRP, topKcrsi, cri-rbi-RSRP, top1cri-rbi-RSRP, topKcri-rbi, crsi-rbi-RSRP, top1crsi-rbi-RSRP, topKcrsi-rbi, top1RSRPdiff, top1 / K, and topK / 1, where the parameter cri-RSRP is used to instruct the terminal to report CRI and RSRP, and the parameter top1cri-R SRP is used to instruct the terminal to report the CRI and corresponding RSRP of the beam with the best RSRP predicted by the spatial beam prediction model. The parameter topKcri is used to instruct the terminal to report the CRI of the K beams with the best RSRP predicted by the spatial beam prediction model. The parameter crsi-RSRP is used to instruct the terminal to report CRSI and RSRP. top1crsi-RSRP is used to instruct the terminal to report the CRSI and corresponding RSRP of the beam with the best RSRP predicted by the spatial beam prediction model. The parameter topKcrsi is used to instruct the terminal to report the CRSI of the K beams with the best RSRP predicted by the spatial beam prediction model. The parameter cri-rbi- RSRP is used to instruct the terminal to report CRI, RBI and RSRP. The parameter top1cri-rbi-RSRP is used to instruct the terminal to report the CRI, RBI and corresponding RSRP of the optimal beam predicted by the spatial beam prediction model. The parameter topKcri-rbi is used to instruct the terminal to report the CRI and RBI of the optimal K beams predicted by the spatial beam prediction model. The parameter crsi-rbi-RSRP is used to instruct the terminal to report CRSI, RBI and RSRP. The parameter top1crsi-rbi-RSRP is used to instruct the terminal to report the CRSI, RBI and corresponding RSRP of the optimal beam predicted by the spatial beam prediction model. topKcrsi-rbi is used to indicate the CRSI and RBI of the optimal K beams predicted by the terminal report, the parameter top1RSRPdiff is used to indicate the RSRP difference between the optimal beam predicted by the spatial beam prediction model reported by the terminal and the optimal beam obtained by actual measurement, the parameter top1 / K is used to indicate whether the optimal beam predicted by the spatial beam prediction model reported by the terminal belongs to the optimal K beams obtained by actual measurement. If so, it can be reported as 1, otherwise it can be reported as 0. The parameter topK / 1 is used to indicate whether the optimal beam obtained by the terminal actual measurement belongs to the optimal K beams predicted by the spatial beam prediction model. If so, it can be reported as 1, otherwise it can be reported as 0.

[0084] In some embodiments, the second period included in the first group of second configuration information is greater than the second period included in the second group of second configuration information. That is, the second period for the terminal configured by the first group of second configuration information to perform measurement and reporting on the reference signal resource set is greater than the second period for the terminal configured by the second group of second configuration information to perform measurement and reporting on the reference signal resource set. Exemplarily, the first group of second configuration information may be used to configure the period and time offset information for measurement and reporting of the reference signal corresponding to the training phase of the spatial beam prediction model, and the second group of second configuration information may be used to configure the period and time offset information for measurement and reporting of the reference signal corresponding to the monitoring phase of the spatial beam prediction model.

[0090] In an optional embodiment of the present application, the indication information of the at least one reference signal resource includes first index information and second index information, wherein the first index information represents the index information of the first reference signal resource in the at least one reference signal resource, and the second index information represents the index information of the last reference signal resource in the at least one reference signal resource; or, the indication information of the at least one reference signal resource includes bitmap information of the at least one reference signal resource in the reference signal resource set.

[0091] In an optional embodiment of the present application, the method may also include: the terminal receives second information sent by the network device, the second information at least including a first group of second configuration information associated with the first group of first configuration information and a second group of second configuration information associated with the second group of first configuration information; wherein, the second configuration information is used to configure the second period and second time offset information for the terminal to report the measurement results of the reference signal resource set.

[0092] In an optional embodiment of the present application, the second information also includes the reporting amount corresponding to each of the two groups of second configuration information, and / or the second information also includes index information or configuration information of the uplink transmission resources corresponding to each of the two groups of second configuration information.

[0093] In an optional embodiment of the present application, the second information includes a first reporting amount corresponding to the first group of second configuration information and a second reporting amount corresponding to the second group of second configuration information; wherein the first reporting amount includes at least one of the following: CRI and RSRP; CSI-RS resource set index and RSRP; CRI, receive beam index and RSRP; CSI-RS resource set index, receive beam index and RSRP; and / or, the second reporting amount includes at least one of the following: CRI and RSRP; CRI and RSRP of the reference signal with the highest RSRP; CRI of each of the top K reference signals with the highest RSRP; K is an integer greater than 1; CSI-RS resource set index and RSRP; CSI-RS resource set index and RSRP of the reference signal with the highest RSRP; CSI-RS resource set index of each of the top K reference signals with the highest RSRP; CRI , receive beam index and RSRP; CRI, receive beam index and RSRP of the reference signal with the highest RSRP; CRI and receive beam index of each of the top K reference signals with the highest RSRP; CSI-RS resource set index, receive beam index and RSRP; CSI-RS resource set index, receive beam index and RSRP of the reference signal with the highest RSRP; CSI-RS resource set index and receive beam index of each of the top K reference signals with the highest RSRP; RSRP difference between the predicted reference signal with the highest RSRP and the measured reference signal with the highest RSRP; a first parameter characterizing whether the predicted reference signal with the highest RSRP belongs to or does not belong to the top K measured reference signals with the highest RSRP; a second parameter characterizing whether the measured reference signal with the highest RSRP belongs to or does not belong to the predicted top K reference signals with the highest RSRP.

[0094] In an optional embodiment of the present application, the second period included in the first group of second configuration information is greater than the second period included in the second group of second configuration information.

[0095] In an optional embodiment of the present application, the uplink transmission resource is carried on PUCCH or PUSCH.

[0096] The communication scheme of the embodiment of the present application is described below in conjunction with specific application scenarios.

[0097] This example uses a network device with 32 transmit beams and a terminal with 4 receive beams. To predict the transmit beams corresponding to the network device, each data collection scan requires scanning all 128 (32×4) beam pairs, and the terminal reports the optimal receive beam quality corresponding to the 32 transmit beams. In this example, the semi-persistent CSI resource set identifier (ID) used for training and monitoring is 1. The period and time offset information corresponding to different stages of this resource set are configured as follows:

[0098] NZP-CSI-RS-Resource::= SEQUENCE{

[0099] periodicityAndOffset1 slots640 0

[0100] periodicityAndOffset2 slots40 0}

[0101] Among them, the parameter periodicityAndOffset1 is used to configure the sending period of the semi-persistent CSI resource set (that is, the first period included in the first group of first configuration information) to 640 time slots, and the time offset information (that is, the first time offset information included in the first group of first configuration information) is 0; the parameter periodicityAndOffset2 is used to configure the sending period of the semi-persistent CSI resource set (that is, the first period included in the second group of first configuration information) to 40 time slots, and the time offset information (that is, the first time offset information included in the second group of first configuration information) is 0.

[0102] The semi-persistent CSI-RS resource set corresponds to the reporting period and offset, reporting amount, and uplink resource configuration in the training and monitoring phases as follows:

[0103] Among them, the parameter periodicityAndOffset3 is used to configure the terminal's reporting period of the measurement results of the semi-persistent CSI resource set (that is, the second period included in the first group of second configuration information) to be 640 time slots, and the time offset information (that is, the second time offset information included in the first group of second configuration information) to be 320; the parameter periodicityAndOffset4 is used to configure the terminal's reporting period of the measurement results of the semi-persistent CSI resource set (that is, the second period included in the second group of second configuration information) to be 40 time slots, and the time offset information (that is, the second time offset information included in the second group of second configuration information) to be 20. The parameter pucch-CSI-ResourceList is used to configure the uplink transmission resources (for example, carried on PUCCH) used by the terminal to report the measurement results of the semi-persistent CSI resource set. Specifically, it may include the index information or configuration information of the uplink transmission resources corresponding to the parameter periodicityAndOffset3 (shown by the parameter PUCCH-CSI-Resource1 in this example), and the index information or configuration information of the uplink transmission resources corresponding to the parameter periodicityAndOffset4 (shown by the parameter PUCCH-CSI-Resource2 in this example). The parameter reportQuantity is used to configure the reporting quantities corresponding to periodicityAndOffset3 and periodicityAndOffset4, respectively. The reporting quantity corresponding to periodicityAndOffset3 is cri-RSRP, which instructs the terminal to report CRI and RSRP, and the reporting quantity corresponding to periodicityAndOffset4 is top1RSRPdiff, which instructs the terminal to report the difference between the RSRP of the optimal beam predicted by the spatial beam prediction model and the RSRP of the optimal beam actually measured.

[0104] FIG7 is a diagram illustrating the structure of the first MAC CE in the model training phase and the model monitoring phase, respectively, of an embodiment of the present application. Referring to FIG5 and FIG7 , when collecting data for model training, the first MAC CE may be used to activate semi-persistent CSI resource set 1 and configure it using a larger resource set period (640 time slots), i.e., the parameter A / D takes the value of "1" and the parameter P takes the value of 0 (corresponding to a larger period). Simultaneously, the second MAC CE may be used to activate CSI-ReportConfig with ID=1 (i.e., the reporting configuration corresponding to the semi-persistent CSI resource set) and activate the corresponding larger reporting period, i.e., the reporting period and offset of the measurement results of the semi-persistent CSI resource set on the PUCCH are 640 and 320 time slots, respectively. Referring to the aforementioned configuration example, the uplink transmission resource used may be PUCCH-CSI-Resource1, and the reporting amount may be cri-RSRP.

[0105] When the model completes training and enters the inference phase, the corresponding MACCE can be used to deactivate the semi-persistent CSI resource set 1 and the semi-persistent reporting of the corresponding measurement results.

[0106] When model inference encounters events such as BFR and the number of NACK feedbacks exceeding the threshold, the model performance needs to be monitored. The network device can use the first MACCE to activate the resource subset of semi-persistent CSI resource set 1 (for example, the reference signal ID is 1 to 64) and configure it with a smaller resource set period (40 time slots) based on the terminal position. Please refer to Figures 5 and 7. The parameter A / D value is "1", the parameter P value is 1 (corresponding to a smaller period), and the parameter start resource 1 and the parameter ending resource 64 respectively indicate that the starting reference signal ID of the activated resource subset is 1 and the ending reference signal ID is 64.

[0107] In addition, a second MAC CE can be used to activate CSI-ReportConfig with ID = 1 and a corresponding smaller reporting period. That is, the reporting period and offset of the measurement results of the upper half persistent CSI resource set of the PUCCH are 40 and 20 time slots, respectively. Referring to the example of the aforementioned configuration, the uplink transmission resource used can be PUCCH-CSI-Resource2, and the reporting amount can be top1RSRPdiff. After receiving the terminal report, the network device can decide whether the model needs to be updated / switched / fallbacked based on top1RSRPdiff.

[0108] In related technologies, CSI resource configuration can only be configured for one period of a semi-persistent resource set. Similarly, reporting of CSI-related measurement results can only be configured for one periodic / semi-persistent resource set, which can contain up to 64 reference signals. However, the semi-persistent resource set must be activated twice throughout the entire process of model training, inference, and monitoring for spatial beam prediction. This activation is used for data collection in both the training and monitoring phases. All corresponding beam pair sets, setA, have different periods, reporting amounts, and potentially different uplink resources. This configuration is not possible with CSI reporting configurations in related technologies.

[0109] In this example, the network device can configure two periods and offsets for the semi-persistent resource set through high-level RRC signaling, and indicate the period, offset, and resource set subset to be activated / deactivated through the semi-persistent resource set activation / deactivation MAC CE (first MAC CE); at the same time, two sets of reporting periods and offsets, reporting amounts, and uplink resources can also be configured through high-level RRC signaling, corresponding to different semi-persistent resource set periods respectively, and can use one semi-persistent CSI reporting configuration (i.e., CSI-ReportConfig) to implement measurement reporting of all beam pairs set A in different stages of the entire process of model training, reasoning, and monitoring in beam prediction based on the AI ​​model. The semi-persistent CSI reporting configuration can adapt to the requirements of different resource set periods, measurement subsets, reporting periods, reporting amounts, and uplink resources in the training and monitoring stages.
