[0002] In a wireless communication system, beam management (BM) is a core technology to ensure efficient transmission of signals, and its performance directly determines the system capacity and communication reliability, especially in high-frequency bands such as millimeter waves and terahertz. Traditional beam management has bottlenecks such as large signaling overhead and insufficient dynamic adaptability in high-frequency scenarios. At present, with the development of artificial intelligence (AI) and machine learning (ML) technologies, AI / ML technologies have been gradually introduced into beam management, that is, the prediction ability of an AI / ML model can replace the full measurement process of scanning all possible beam directions in the traditional scheme, thereby reducing the signaling resource occupation caused by beam measurement and feedback, and enhancing the system's adaptability to dynamic environments such as user movement and changes in shielding.

The 5G system can also be referred to as a new radio (NR) system.

[0059] The network where the network device is located has strong computing capability, which can be provided by a computing node included in the network, or can be provided by the network device itself. When the computing capability can be provided by the computing node included in the network, the network device can be connected with one or more computing nodes in the network, and the computing nodes can process the task data by distributing the task data received from the terminal device to the computing nodes. The computing node can be, for example, a multi-access edge computing (MEC) server, a distributed cloud node, a quantum computing node, a computing host, etc. In the computing node, one or more computing units can be included to implement concurrent processing of the task data, and the computing unit can be, for example, a central processing unit (CPU), a graphics processing unit (GPU), etc.

[0061] The network device provides services for a cell, and a terminal device communicates with the cell through transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network device. The cell can belong to a macro base station (for example, a macro eNB or a macro gNB, etc.), or a base station corresponding to a small cell. The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, etc., and has the characteristics of small coverage and low transmit power, and is suitable for providing high-speed data transmission services.

[0062] Alternatively, the foregoing device in communication with the terminal device and the computing node can be regarded as a whole as the network device involved in the present application.

[0063] The terminal device in the embodiments of the present application can also be referred to as: user equipment (user equipment, UE), mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal can be widely applied to various scenes for communication. The scene includes, for example, but is not limited to at least one of the following: enhanced mobile broadband (enhanced mobile broadband, eMBB), ultra-reliable low-latency communication (ultra-reliable low-latency communication, URLLC), massive machine type communication (massive machine-type communications, mMTC), device-to-device (device-to-device, D2D), vehicle-to-everything (vehicle to everything, V2X), machine type communication (machine-type communication, MTC), Internet of Things (internet of things, IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, or smart city, etc. The terminal can be a mobile phone (such as a mobile phone 120a, 120d, 120f in Figure 1 ), a tablet computer, a computer with wireless transceiver function (such as a computer 120g in Figure 1 ), a wearable device, a vehicle (such as 120b shown in Figure 1 ), a drone, a helicopter, an airplane (such as 120c in Figure 1 ), a ship, a robot, a mechanical arm, or a smart home device (such as a printer 120e in Figure 1 ), etc. The present application does not limit the specific technology and specific device form of the terminal.

[0064] By way of example and not limitation, in this application, the terminal device can be a terminal device in an XR system. As a key field of future human-computer interaction and digital content presentation, XR technology integrates VR, AR, and MR technologies, and its main technical feature is to seamlessly connect the digital world and the physical world through highly immersive experiences, and to realize deep interaction between users and virtual environments and real scenes. By way of example, the terminal device in the embodiments of the present application can be an XR device, which is a type of intelligent terminal designed for immersive experiences. By integrating display, sensing, computing, and communication technologies, virtual content or augmented information is superimposed on the user's field of view, or a completely virtual interactive space is constructed. XR devices include, but are not limited to, head-mounted displays, smart glasses, handheld interactive devices, and holographic projection devices. XR devices widely support cloud interaction, and through the network, high-precision models, dynamic scene data, or AI inference services are obtained in real time, thereby breaking through the limitations of local computing power and promoting the landing of complex applications such as the metaverse and remote collaboration.

[0065] Currently, AI / ML models for beam prediction can be deployed on the terminal side. The terminal can learn historical beam measurement data, user movement trajectories, channel variation characteristics, and environmental information, etc. through the AI / ML model to predict future beams and obtain related information of the predicted beams, such as beam direction parameters (azimuth angle, elevation angle, etc.), signal-to-interference-plus-noise ratio (SINR), validity time, etc. When the terminal measures the actual beam, the actual beam can be used to verify the predicted beam to determine the prediction accuracy of the AI / ML model. For example, the prediction accuracy of the predicted beam can be determined by judging the beam direction difference and the reference signal received power (RSRP) difference between the predicted beam and the actual beam corresponding to the predicted beam. By way of example, whether the predicted beam and the actual beam corresponding to the predicted beam are an effective beam association pair can be determined according to whether the difference between the predicted beam and the actual beam corresponding to the predicted beam meets a preset accuracy requirement. If the difference between the predicted beam and the actual beam corresponding to the predicted beam meets the preset accuracy requirement, they are an effective beam association pair.

[0066] In this scenario, the total number of beam association pairs that the terminal needs to monitor can be different for different terminals, different cells where the terminal is located, and the like. For example, when terminal 1 is located in cell 1, it needs to monitor 30 beam association pairs, when terminal 1 is located in cell 2, it needs to monitor 25 beam association pairs, when terminal 2 is located in cell 1, it needs to monitor 50 beam association pairs, and the like. In subsequent embodiments, for ease of description, the total number of beam association pairs that the terminal needs to monitor is referred to as N, and the number of effective beam association pairs obtained through measurement is referred to as Np. Wherein, N can be pre-defined by the protocol, or can be pre-issued to the terminal by the access network device.

[0067] The terminal currently needs to report the number of effective beam association pairs obtained through measurement to the network side as a beam accuracy indicator (BAI), such as sending BAI to the access network device. The access network device determines Np of the terminal according to the received BAI, and calculates the BAI level according to the pre-configured N corresponding to the terminal. Wherein, the current calculation method of BAI level is BAI level=Np / N. The access network device determines the prediction accuracy of the AI / ML model of the terminal according to the BAI level corresponding to the terminal, and when the BAI level corresponding to the terminal represents that the prediction accuracy of the AI / ML model is low, the corresponding signaling is issued to the terminal to adjust the AI / ML model deployed on the terminal, and the prediction accuracy of the AI / ML model is improved.

[0068] However, in the above existing scheme, the terminal needs to report the specific value of Np to the network side. For example, when N=200 beam association pairs, if Np=150, the specific value "150" needs to be transmitted to the network side through signaling. However, the number of binary coded bits of Np increases with N. When N=1024, 10 binary bits (0-1023) are needed, resulting in the problem of occupying more signaling resources, significantly increasing the load of signaling resources.

[0069] In addition, the terminal simply reports the specific value of Np to the network side, which cannot reflect the actual efficiency of beam management through the AI / ML model. For example, when Np=150, if N=200, it represents a prediction accuracy of 75%, and if N=300, it only represents a prediction accuracy of 50%, and the network side cannot directly determine the performance of the AI / ML model of the terminal according to the specific value of Np.

[0070] Therefore, the communication method provided in the present application can avoid the problem of occupying more signaling resources caused by reporting the specific value of Np to the network side, thereby reducing the signaling resource overhead. Moreover, directly reporting the BAI level to the network side can intuitively reflect the actual performance of the beam management by the AI / ML model, thereby improving the efficiency and accuracy of the network side in judging the AI / ML model performance of the terminal.

[0071] The communication method of the present application will be described in detail below with reference to the accompanying drawings. The execution subject of the embodiments shown in the present application is a terminal and an access network device, and the specific form and quantity of each device shown are only examples and should not constitute any limitation on the implementation of the method provided in the present application. The terminal device in the embodiments of the present application can be a terminal device itself, or a chip, chip system or processor supporting the terminal device to implement the task processing method, or a logic module or software capable of implementing all or part of the functions of the terminal device. The access network device in the embodiments of the present application can be an access network device itself, or a chip, chip system or processor supporting the access network device to implement the task processing method, or a logic module or software capable of implementing all or part of the functions of the access network device, which is not specifically limited in the present application.

[0072] Figure 2 A flowchart of a communication method provided in the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the method can include the following steps. Figure 2

[0073] S201, the terminal sends first information to the access network device.

[0074] Correspondingly, the access network device receives the first information sent by the terminal.

[0075] The first information is used to indicate the BAI level of the terminal, and the BAI level is related to the number of first beam association pairs measured by the terminal. The first beam association pair includes a beam association pair measured by the terminal that meets the preset accuracy requirement.

[0076] The preset accuracy requirement can include at least one of a beam direction accuracy requirement, an RSRP accuracy requirement, etc. For example, whether the beam direction difference of the beam association pair meets the beam direction accuracy requirement and / or whether the RSRP difference of the beam association pair meets the RSRP accuracy requirement can be used to determine whether the beam association pair measured by the terminal is the first beam association pair.

[0077] ​For example, the beam direction difference of the beam association pair is less than or equal to 5°, and the RSRP difference of the beam association pair is less than or equal to 3dB, which can be set as meeting the beam direction accuracy requirement and the RSRP accuracy requirement. Specifically, the above accuracy requirements can also be dynamically adjusted according to the communication frequency band or the beam width. For example, for the Sub-6GHz frequency band (wide beam), the beam direction accuracy requirement can be set as meeting the beam direction accuracy requirement when the beam direction difference is less than or equal to 15°; for the millimeter wave or terahertz frequency band (narrow beam), the beam direction accuracy requirement can be set as meeting the beam direction accuracy requirement when the beam direction difference is less than or equal to 5°, and so on.

[0078] For example, the beam direction difference of the beam association pair is less than or equal to 5°, and the RSRP difference of the beam association pair is less than or equal to 3dB, which can be set as meeting the beam direction accuracy requirement and the RSRP accuracy requirement. Specifically, the above accuracy requirements can also be dynamically adjusted according to the communication frequency band or the beam width. For example, for the Sub-6GHz frequency band (wide beam), the beam direction accuracy requirement can be set as meeting the beam direction accuracy requirement when the beam direction difference is less than or equal to 15°; for the millimeter wave or terahertz frequency band (narrow beam), the beam direction accuracy requirement can be set as meeting the beam direction accuracy requirement when the beam direction difference is less than or equal to 5°, and so on.

[0079] In this step, the terminal can determine the beam association pair according to the predicted beam obtained by the AI / ML model corresponding to the actual beam. Then, according to the beam difference between the predicted beam and the actual beam in each beam association pair and the preset accuracy requirement, the number of the first beam association pair included in the beam association pair determined by the terminal, i.e., the aforementioned Np, is determined. And the BAI level of the terminal is determined based on Np.

[0080] In one possible implementation, the BAI level of the terminal can be determined based on the number of the beam association pairs that need to be measured by the terminal (i.e., the aforementioned N) and Np.

[0081] In another possible implementation, the BAI level of the terminal can be determined based on the number of the beam association pairs actually measured by the terminal (which can be referred to as Nd) and Np.

[0082] After the terminal determines its own BAI level, the terminal can send the first information indicating the BAI level to the access network device, so that the access network device determines the BAI level corresponding to the terminal according to the first information.

[0083] Optionally, the first information can indicate a specific BAI level, for example, different first information can be sent according to different BAI levels; or the first information carries the BAI level, or the first information carries an identifier indicating the BAI level, and so on.

[0084] The first information in this step can be sent by the terminal to the access network device in the following ways: the terminal can carry the first information through physical layer (Layer 1, L1) signaling, or based on a channel state information (Channel State Information Report Framework, CSI) reporting framework, etc., and complete the transmission of the first information through an uplink channel such as a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0085] S202. The access network device controls the beam management model of the terminal according to the BAI level.

[0086] The beam management model is an AI / ML model deployed on the terminal and used for beam management. The access network device can perform different controls on the beam management model of the terminal for different BAI levels of the terminal. When the BAI level is high, the prediction accuracy of the beam management model is high, and the access network device can only perform statistics on the performance of the beam management model, or can relax the monitoring requirements for the beam management model (for example, the monitoring interval of the beam management model can be relaxed from 1 ms to 3 ms to reduce uplink signaling overhead and reduce terminal power consumption); when the BAI level is low, the prediction accuracy of the beam management model is low, and the access network device can adjust the model parameters of the beam management model of the terminal or perform model rollback operations through downlink signaling control to optimize the beam management model, thereby improving the prediction accuracy of the beam management model.

[0087] For example, assuming that the BAI level includes two levels of a first level and a second level, the first level represents a high prediction accuracy of the beam management model, and the access network device can only perform statistics on the performance of the beam management model, or can relax the monitoring requirements for the beam management model. The second level represents a low prediction accuracy of the beam management model, and the access network device can adjust the model parameters of the beam management model of the terminal or perform model rollback operations through downlink signaling control to optimize the beam management model, thereby improving the prediction accuracy of the beam management model.

[0088] In this step, the access network device is configured to control the downlink signaling of the terminal beam management model, which can be transmitted through Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC-CE), Downlink Control Information (DCI), etc.

[0089] The method provided by the embodiments of the present application can avoid the problem of excessive signaling resource occupation caused by the terminal reporting the specific value of Np to the access network device, thereby reducing the signaling resource overhead. Moreover, the terminal directly reports the BAI level to the access network device, which can intuitively reflect the actual performance of the beam management by the AI / ML model, thereby improving the efficiency and accuracy of the access network device in judging the AI / ML model performance of the terminal.

[0090] Next, how the first information in the communication method provided by the present application indicates the BAI level will be described in detail.

[0091] Specifically, the first information includes a first byte for indicating the BAI level of the terminal. For example, the first information can be multiplexed with other uplink signaling for transmission, and the uplink signaling includes multiple bytes, some of which constitute the first information, and the first information includes at least the first byte (e.g., it can only include the first byte, or it can include the first byte and other bytes for indicating other information). The first byte may, for example, include the BAI level, or it may be an identifier for indicating the BAI level, etc.

[0092] In one possible implementation, the first byte includes a target bit for indicating the BAI level, and different values of the target bit correspond to different BAI levels. The number of bits of the target bit may, for example, be 1 bit, 2 bits, or more bits, etc. The number of bits of the target bit can be pre-defined by the protocol, or it can be pre-indicated to the terminal by the network side, etc. The more the number of bits of the target bit is, the more detailed the BAI level can be divided, e.g., when the target bit is 1 bit, it can represent at most 2 BAI levels; when the target bit is 2 bits, it can represent at most 4 BAI levels, etc. The present application does not limit the number of bits of the target bit, which can be set according to actual needs.

[0093] Exemplarily, the BAI level indicated by the first information is introduced below by taking 1 bit and 2 bit as the target bit respectively.

[0094] When the target bit is 1 bit, the value of the target bit can include at least one of 0 and 1. For example, when the value of the target bit includes 0 and 1, the target bit of 0 and the target bit of 1 represent different BAI levels. For example, the target bit of 1 represents the first level, indicating that the prediction accuracy of the beam management model is high, and the access network device can only perform statistics on the performance of the beam management model, or can relax the monitoring requirements of the beam management model. The target bit of 0 represents the second level, indicating that the prediction accuracy of the beam management model is low, and the access network device can adjust the model parameters of the beam management model of the terminal through downlink signaling control or perform model fallback operation to optimize the beam management model, thereby improving the prediction accuracy of the beam management model. Alternatively, the target bit of 0 represents the first level, and the target bit of 1 represents the second level.

[0095] Optionally, the target bit can also include only 0 or 1, that is, only represent the first level or the second level. In this implementation, the first information sent by the terminal only represents that the BAI level is the first level or the second level. When the terminal sends the first information, it represents that the BAI level of the terminal is in the first level or the second level indicated by the first information. When the terminal does not send the first information at a specific time, it represents that the BAI level of the terminal is in the second level or the first level not indicated by the first information.

[0096] When the target bit is 2 bits, the value of the target bit can include at least one of 00, 01, 10, 11, etc. For example, when the value of the target bit includes 00, 01, 10, and 11, the four values can represent four different BAI levels. For example, the BAI levels include level 1 (assuming corresponding to 11), level 2 (assuming corresponding to 10), level 3 (assuming corresponding to 01), and level 4 (assuming corresponding to 00). Exemplarily, the specific meanings of the above four BAI levels can be as follows:

[0097] The level 1 represents that the prediction accuracy of the beam management model is excellent. When the access network device receives the first information indicating that the BAI level is level 1, or receives the first information multiple times (such as reaching a preset number) within a preset time window, the access network device controls the terminal to perform model monitoring relaxation operation, or does not send downlink signaling to the terminal, or does not send downlink signaling to the terminal and only performs statistics on the performance of the beam management model, etc.

[0098] The level 2 represents the prediction accuracy of the beam management model. When the access network device receives the first information indicating that the BAI level is level 2, or receives the first information multiple times (such as a preset number of times) within a preset time window, the access network device controls the terminal to perform a model monitoring requirement through downlink signaling, or does not send downlink signaling to the terminal.

[0099] The level 3 represents the prediction accuracy of the beam management model. When the access network device receives the first information indicating that the BAI level is level 3, or receives the first information multiple times (such as a preset number of times) within a preset time window, the access network device controls the terminal to perform a model modification operation through downlink signaling. The model modification operation may be, for example, switching the beam management model (such as switching to another type of beam management model, or switching to another different beam management model of the same type, different beam management models use different beam management algorithms), or modifying the model parameters in the beam management model (such as modifying the parameter values, modifying the number of model parameters, etc.).

[0100] The level 4 represents an abnormal beam management model. When the access network device receives the first information indicating that the BAI level is level 4, or receives the first information multiple times (such as a preset number of times) within a preset time window, the access network device can control the terminal to perform a model rollback operation through downlink signaling. The model rollback refers to closing the beam management model and using a traditional beam management method for beam management.

[0101] The method provided by the embodiments of the present application sets a first byte for indicating the BAI level of the terminal in the first information, and the first byte contains target bits of different bit numbers. Different BAI levels are flexibly divided according to the bit number and the value of the target bits by using the mode that different values of the target bits correspond to different BAI levels. Different BAI levels correspond to different prediction accuracy of the beam management model. The access network device can take different operation strategies for the beam management model of the terminal according to the received first information indicating different BAI levels, so as to more accurately and efficiently manage and optimize the beam management model of the terminal, improve the performance of the beam management model, improve the communication quality, and save the resource occupation in the signaling.

[0102] Next, how the terminal in the communication method provided by the present application calculates and divides the BAI level is described in detail.

[0103] The BAI level is related to the quotient of the number of the first beam association pair and the target value. The target value includes the total number of the beam association pairs or the number of the second beam association pair, and the second beam association pair is the beam association pair measured by the terminal. The total number of the beam association pairs is N in the step S201, and the second beam association pair is Nd in the step S201.

[0104] When the BAI level is related to the quotient of the number of first beam association pairs and the total number of beam association pairs, the terminal's BAI level can be determined specifically based on the value obtained from Np / N. Here, N can be related to factors such as the terminal and the cell where the terminal is located, it can be predefined by the protocol, or it can be pre-issued to the terminal by the access network equipment, etc. For example, assuming N is 50 and Np is 30, then the value of Np / N is 30 / 50 = 0.6, or it can be converted to a percentage of 60%, or 60, etc.

[0105] When the BAI level is related to the quotient of the number of first beam association pairs and the number of second beam association pairs, the terminal's BAI level can be determined specifically based on the value obtained from Np / Nd. For example, assuming N is 50 and the terminal measures 40 beam association pairs (meaning 10 beam association pairs were not measured), then Nd is 40. Continuing to assume Np is 20, the value of Np / Nd is 20 / 40 = 0.5, or it can be converted to a percentage of 50% or 50, etc.

[0106] To make it easier to understand, the following is an example. Figure 3 The above-mentioned N, Nd, and Np are described in detail by example. Figure 3 This is a schematic diagram of a beam association pair scenario provided in an embodiment of this application. Figure 3 As shown, the total number of beam association pairs N (i.e. Figure 3 The maximum number of valid samples N (referring to the maximum number of beam association pairs that the terminal needs to calculate) is related to the terminal and the cell where the terminal is located. The total number of beam association pairs N corresponding to different terminals and different cells can be partially different. The protocol can predefine the total number of beam association pairs N corresponding to the terminal based on at least one of the following: terminal type, terminal identifier, and the cell where the terminal is located. Alternatively, the access network device can pre-indicate the total number of beam association pairs N corresponding to the terminal. After determining the total number of beam association pairs N, the terminal determines the number of beam association pairs actually measured by the terminal (i.e., the number of second beam association pairs Nd) based on its measurement of the actual beam. Figure 3 The number of valid samples measured by the terminal. Among the beam association pairs actually measured by the terminal, the number Np of the first beam association pairs that meet the preset accuracy requirements is determined based on whether these beam association pairs meet the preset accuracy requirements. Figure 3 The number of valid samples that meet the adjustment criteria obtained from the mid-terminal measurement.

[0107] Taking the total number N of beam association pairs as an example, which is pre-indicated to the terminal by the access network device, the method further includes:

[0108] The access network device sends fourth information to the terminal. Correspondingly, the terminal receives the fourth information sent by the access network device. The fourth information is used to indicate the total number N of beam association pairs.

[0109] When the total number N of beam association pairs is related to the cell where the terminal is located, the fourth information can be sent by the access network device to the terminal after determining the cell where the terminal is located according to the cell access behavior of the terminal, or after detecting that the terminal has performed cell switching. For example, when the terminal initially accesses a cell, the access network device determines the total number N of beam association pairs corresponding to the terminal according to the terminal and the cell accessed by the terminal, and generates corresponding fourth information and sends it to the terminal. For another example, after the terminal completes cell switching, the access network device determines the total number N of beam association pairs corresponding to the terminal according to the terminal and the cell accessed by the terminal after cell switching, and generates corresponding fourth information and sends it to the terminal.

[0110] After determining the quotient of the number of the first beam association pair and the target value, in one possible implementation, the BAI level of the terminal can be directly determined according to the quotient, and the mapping relationship between the quotient and the BAI level. In another possible implementation, the BAI level of the terminal can be determined according to the value interval corresponding to the BAI level and the quotient.

[0111] Taking the determination of the BAI level of the terminal according to the value interval and the quotient as an example, for example, the complete value interval corresponding to the quotient (that is, the minimum Nd is 0, and the maximum is the target value, and the complete value interval corresponding to the quotient is [0, 100%]) can be divided into multiple value intervals, and the BAI level of the terminal can be determined according to the BAI level corresponding to the value interval where the quotient is located.

[0112] For example, the complete value interval corresponding to the quotient can be divided into two parts. Assuming that the division threshold is 37.5%, when the quotient is located in [0, 37.5%], the BAI level of the terminal is the second level representing lower model prediction accuracy; and when the quotient is located in (37.5%, 100%], the BAI level of the terminal is the first level representing higher model prediction accuracy.

[0113] Alternatively, the complete value interval corresponding to the quotient can be divided into four parts. Figure 4 A scene diagram of a value interval of a BAI level provided for an embodiment of the present application. As shown in the figure, Figure 4As shown, assuming that the division thresholds are 25%, 37.5%, and 75% respectively, when the quotient value is located in [0, 25%), the BAI level of the terminal is the aforementioned level 4 (the target bits indicating the BAI level can be 00), that is, it is represented that the AI / ML model is abnormal; when the quotient value is located in (25%, 37.5%], the BAI level of the terminal is the aforementioned level 3 (the target bits indicating the BAI level can be 01), that is, it is represented that the prediction accuracy of the AI / ML model is low; when the quotient value is located in (37.5%, 75%], the BAI level of the terminal is the aforementioned level 2 (the target bits indicating the BAI level can be 10), that is, it is represented that the prediction accuracy of the AI / ML model is normal; and when the quotient value is located in (75%, 100%], the BAI level of the terminal is the aforementioned level 1 (the target bits indicating the BAI level can be 11), that is, it is represented that the prediction accuracy of the AI / ML model is excellent.

[0114] Next, how the terminal determines the value range of the quotient value corresponding to the BAI level is described in detail.

[0115] In a possible implementation, the value range of the quotient value corresponding to the BAI level is predefined by the protocol, and the terminal can determine the value range of the quotient value corresponding to different BAI levels according to the communication protocol. For example, the protocol can predefine multiple value ranges as the value ranges of the quotient values corresponding to different BAI levels; or the protocol can predefine an interval step for determining the value range, and the terminal can divide the value range of the quotient value corresponding to the BAI level according to the interval step.

[0116] In another possible implementation, the value range of the quotient value corresponding to the BAI level is pre-configured by the access network device and sent to the terminal. In this implementation, the access network device pre-configures and sends second information to the terminal. Correspondingly, the terminal receives the second information sent by the access network device. The second information is used to indicate the value range of the quotient value corresponding to the BAI level. For example, the second information can directly indicate multiple value ranges as the value ranges of the quotient values corresponding to different BAI levels; or the second information includes multiple value ranges of the quotient values corresponding to different BAI levels.

[0117] Alternatively, the value range of the quotient value corresponding to the BAI level is determined based on an interval step, and the interval step is pre-configured by the access network device and sent to the terminal. In this implementation, the access network device pre-configures and sends third information to the terminal. Correspondingly, the terminal receives the third information sent by the access network device. The third information is used to indicate the interval step. The terminal can divide the value range of the quotient value corresponding to the BAI level according to the interval step. Optionally, the third information can also be the aforementioned second information, that is, the second information is directly used to indicate the interval step.

[0118] Alternatively, the value range of the quotient corresponding to the BAI level is determined based on a division threshold, which can be previously delivered by the access network device to the terminal or can be predefined by the protocol. If the division threshold is previously delivered by the access network device to the terminal, the access network device can indicate the division threshold through the second information or the third information, and the terminal can divide the value range of the quotient corresponding to the BAI level according to the division threshold. For example, if the division threshold is 37.5%, the value range of the quotient corresponding to the BAI level can include (37.5%, 100%] corresponding to the first level, [0, 37.5%] corresponding to the second level.

[0119] In the case where the value range of the quotient corresponding to the BAI level is determined based on an interval step, the access network device or the protocol can directly indicate the specific value of the interval step, or can indicate a step parameter used to calculate the interval step.

[0120] For example, if the specific value of the interval step is directly indicated, assuming that the specific value of the interval step is 25%, the value control can be divided into four parts: [0, 25%), [25%, 50%), [50%, 75%), and [75%, 100%], which can correspond to the aforementioned level 1, level 2, level 3, and level 4, for example. In this case, the second information or the third information indicates 25% (such as indicating a specific identifier representing 25%); or the protocol predefines the interval step as 25%.

[0121] If the step parameter used to calculate the interval step is indicated, the interval step can be obtained by dividing 100% by the step parameter. For example, the step parameter can be a fixed value, such as 2, 4, 8, etc. Alternatively, the step parameter can be set as a positive integer power of 2, and the power can also be used as the step parameter, etc. If the step parameter is a positive integer power of 2, since the positive integer power of 2 has a special form in binary, i.e., only the highest bit is 1 and the remaining bits are all 0, when performing the division operation (dividing 100% by the step parameter to calculate the interval step), for such special numbers, the division can be realized by simple binary bit operations (such as right shift operation), avoiding complex multi-cycle division operation process, thereby improving the efficiency of the terminal in calculating the interval step.

[0122] The method provided by the embodiments of the present application associates the BAI level with the quotient of the number of the first beam association pair and the total number of the beam association pair or the number of the second beam association pair, and determines the BAI level of the terminal according to the relationship between the quotient and the value interval corresponding to different BAI levels. The determination manner of the value interval is flexible and diverse, which can be protocol predefinition, network device delivery, or interval step length-based or partition threshold-based determination (here, a brief introduction of the technical means is supplemented). In this flexible manner, the BAI level is determined, which can comprehensively consider the actual measurement of the terminal and the model accuracy requirement, and can adapt to different accuracy partition requirements by adjusting the determination manner of the value interval (such as changing the interval step length or the partition threshold), so as to more accurately evaluate the prediction accuracy of the beam management model of the terminal, provide a reliable basis for the network device to take a targeted operation strategy for the beam management model of the terminal, improve the effectiveness and flexibility of the communication system for beam management, and improve the communication quality.

[0123] As described in the foregoing embodiments, the target value can be the total number N of the beam association pair, or the number Nd of the second beam association pair. However, in actual scenarios, the terminal cannot measure all the beam association pairs satisfying the total number N in all cases, but can only actually measure part of the beam association pairs, that is, the second beam association pair. If only the number Np of the first beam association pair and the total number N of the beam association pair are used to calculate the BAI level, there can still be a situation of BAI level distortion. Using the actually measured number Nd of the second beam association pair and the number Np of the first beam association pair to calculate the BAI level can further improve the accuracy of the BAI level, thereby improving the accuracy of the AI / ML beam management model deployed on the terminal based on the BAI level adjustment.

[0124] When the target value is the number Nd of the second beam association pair, if Nd is less than N, it indicates that there is a certain loss of the beam association pairs measured by the terminal and the beam association pairs to be measured. If the value of Nd is large when Nd is less than N, the BAI level received by the network device is the BAI level obtained by lacking part of the beam association pairs, which can affect the accuracy of the network device in judging the model parameters, model structure, and other factors of the beam management model on the terminal, resulting in a problem of low accuracy of the control manner of the network device in adjusting the beam management model. Therefore, the communication method provided by the present application can further include that the terminal reports the number Nd of the second beam association pair to the network device, so as to further improve the accuracy of the network device in adjusting the beam management model when the target value is the number Nd of the second beam association pair.

[0125] Specifically, when the target value includes the number of the second beam association pair, the communication method can further include:

[0126] The terminal sends fifth information to the access network device. Correspondingly, the access network device receives the fifth information sent by the terminal. The fifth information is used to indicate the number Nd of the second beam association pairs.

[0127] Optionally, the fifth information can indicate the number Nd of the second beam association pairs by carrying an identifier corresponding to the number Nd of the second beam association pairs, or the number of the second beam association pairs can also be directly carried in the fifth information. Taking the case of directly carrying the number of the second beam association pairs in the fifth information as an example, the number of the second beam association pairs can be carried in the following ways:

[0128] Method 1: The fifth information includes the value of the number of the second beam association pairs. For example, the number of the second beam association pairs is 20, and the fifth information carries the value 20 to represent that the number of the second beam association pairs is 20.

[0129] Method 2: The fifth information includes the logarithmic processing value of the number of the second beam association pairs. For example, the number of the second beam association pairs is N, and the fifth information carries any one of the values such as log2(N+1), ln(N+1), etc. in the form of a logarithmic processing value based on N, to represent that the number of the second beam association pairs is N. For example, if the number of the second beam association pairs is 20, the fifth information can carry log2(20+1)=log221.

[0130] By using the logarithmic processing value of the number of the second beam association pairs to replace the value of the number of the second beam association pairs, when the value range of the number of the second beam association pairs is large, the number of bits of the value to be transmitted can be compressed. For example, when N=1023, 10 bits need to be transmitted, and log2(1023+1)=10 can be compressed to only 4 bits, thereby reducing the signaling overhead of the terminal reporting the number Nd of the second beam association pairs to the access network device.

[0131] Method 3: The fifth information includes a first difference between the total number of beam association pairs and the number of the second beam association pairs. For example, the total number of beam association pairs N is 30, and the number of the second beam association pairs Nd is 20, so the first difference between N and Nd is 30-20=10. Since the total number of beam association pairs N is predefined by the protocol or is previously sent by the access network device to the terminal, the access network device knows the value of the total number of beam association pairs N, and the terminal only needs to upload the first difference between the total number of beam association pairs and the number of the second beam association pairs, and the access network device can determine the value of the number Nd of the second beam association pairs according to the difference and the value of the total number of beam association pairs N.

[0132] Optionally, the first difference value between the total number of the beam association pairs and the number of the second beam association pairs can also be a logarithmic processing value of the first difference value, and the implementation manner is similar to the logarithmic processing of the number of the second beam association pairs in the above-described manner 2, which will not be described here again.

[0133] Manner 4: The fifth information includes a second difference value between the number of the second beam association pairs and the number of the second beam association pairs reported last time.

[0134] For example, the number Nd of the second beam association pairs is 20, and the number Nd' of the second beam association pairs reported last time by the terminal is 30, and it can be determined that the second difference value between Nd' and Nd is 30-20=10. Since the access network device has obtained Nd' as 30 at the time when the terminal reported last time, the access network device can determine the value of the number Nd of the second beam association pairs reported by the terminal this time according to the second difference value and the value of the number Nd' of the second beam association pairs reported last time.

[0135] Optionally, the second difference value between the number of the second beam association pairs and the number of the second beam association pairs reported last time can also be a logarithmic processing value of the second difference value, and the implementation manner is similar to the logarithmic processing of the number of the second beam association pairs in the above-described manner 2, which will not be described here again.

[0136] In this embodiment, the fifth information can be sent to the access network device through different uplink signaling at the same time as the first information, can be sent to the access network device in the same uplink signaling, or the fifth information can also be part of the first information, or the fifth information and the first information are sent to the access network device at different times through different uplink signaling, etc.

[0137] In a possible implementation, the terminal can perform the operation of sending the fifth information to the access network device based on the sending period of the fifth information. The sending period of the fifth information can be a fixed period or a non-fixed period, which can be set according to actual needs, and the present application does not limit this. In this implementation, the sending period of the fifth information can be predefined by a protocol, or can be configured to the terminal in advance by the access network device (for example, the access network device sends sixth information for indicating the sending period of the fifth information to the terminal in advance, the terminal determines the sending period of the fifth information based on the received sixth information, and sends the fifth information to the access network device based on the sending period of the fifth information). The sending period of the fifth information can be the same as the sending period of the first information, or can be different from the sending period of the first information (for example, the sending period of the fifth information can be greater than or equal to the sending period of the first information).

[0138] In another possible implementation, the terminal can trigger the operation of sending the fifth information to the access network device based on a sending condition of the fifth information. The sending condition may, for example, include any one of the following:

[0139] Sending condition 1: in a case where the first difference is greater than a preset difference threshold, the terminal sends the fifth information to the access network device.

[0140] The preset difference threshold may, for example, be 5, 10, 15, or the like. If the first difference is greater than the preset difference threshold, it indicates that the difference between the number Nd of the second beam association pairs and the total number N of the beam association pairs is large, which has a greater impact on the accuracy of the beam management model determined by the access network device. Therefore, the terminal needs to report the number Nd of the second beam association pairs to improve the accuracy of the beam management model determined by the access network device. If the first difference is less than or equal to the preset difference threshold, it indicates that the difference between the number Nd of the second beam association pairs and the total number N of the beam association pairs is small, which has a smaller impact on the accuracy of the beam management model determined by the access network device. Therefore, the terminal can not report the number Nd of the second beam association pairs.

[0141] Optionally, the preset difference threshold can be 0, that is, as long as there is a difference between the number Nd of the second beam association pairs and the total number N of the beam association pairs, the terminal needs to report the number Nd of the second beam association pairs.

[0142] Sending condition 2: in a case where a ratio of the first difference to the total number N of the beam association pairs is greater than or equal to a preset ratio, the terminal sends the fifth information to the access network device.

[0143] The ratio of the first difference to the total number N of the beam association pairs is (N-Nd) / N, and the preset ratio may, for example, be set according to actual needs, which is not limited in the present application. If the ratio is greater than or equal to the preset ratio, it indicates that the difference between the number Nd of the second beam association pairs and the total number N of the beam association pairs is large, which has a greater impact on the accuracy of the beam management model determined by the access network device. Therefore, the terminal needs to report the number Nd of the second beam association pairs to improve the accuracy of the beam management model determined by the access network device. If the ratio is less than the preset ratio, it indicates that the difference between the number Nd of the second beam association pairs and the total number N of the beam association pairs is small, which has a smaller impact on the accuracy of the beam management model determined by the access network device. Therefore, the terminal can not report the number Nd of the second beam association pairs.

[0144] The method provided by the embodiments of the present application, when the target value is the number of the second beam association pairs, allows the terminal to report the number Nd of the second beam association pairs to the access network device, and provides multiple reporting modes of carrying the number information of the second beam association pairs, such as directly carrying the number value, a logarithmic processing value, a difference value from the total number or the last reported number, and the like. With these diversified reporting modes, on the one hand, the appropriate mode can be flexibly selected according to the actual scene, and when the value range of the number of the second beam association pairs is large, the logarithmic processing value is reported to compress the bit number of the required transmission value, thereby reducing the signaling overhead. On the other hand, by reporting the number of the second beam association pairs, the access network device can more comprehensively understand the actual measurement situation of the terminal, avoid the distortion that may occur when the BAI level is calculated only by the number of the first beam association pairs and the total number of the beam association pairs, thereby further improving the accuracy of the access network device in adjusting the beam management model, improving the effectiveness of the communication system in beam management, and ensuring the communication quality.
