[0027] <First Embodiment>

[0028] As mentioned earlier, the introduction of AI in beam management can reduce measurement overhead and delay. In the traditional beam management mechanism, the network side only indicates the optimal downlink transmit beam, and what kind of downlink receive beam is used by the user equipment (UE) side is considered to be an implementation problem of the UE itself. However, in AI-based beam management, the output of the AI ​​model can be an optimal downlink beam pair, that is, it includes both the optimal downlink transmit beam and the optimal downlink receive beam. In this case, the network side and the UE may need to align their understanding of the downlink receive beam. Therefore, it is necessary to provide a new measurement and reporting mechanism for AI-based beam management.

[0029] Figure 1 FIG. 1 shows a functional module block diagram of an electronic device 100 for beam management in wireless communication according to this embodiment. Figure 1 As shown, the electronic device 100 includes: an acquisition unit 101, configured to obtain a measurement result of a user equipment for a downlink beam pair to be measured, wherein the downlink beam pair to be measured includes a downlink transmit beam and a downlink receive beam; and a prediction unit 102, configured to perform beam pair prediction based on the measurement result using an artificial intelligence (AI) model to obtain a prediction output, wherein the prediction output includes an optimal downlink transmit beam, multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam, and a residence time of each optimal downlink receive beam.

[0030] The acquisition unit 101 and the prediction unit 102 may be implemented by one or more processing circuits, which may be implemented as a chip or a processor, for example. Figure 1The various functional units in the electronic device shown in the figure are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation method.

[0031] The electronic device 100 may be located on the network side, for example, at a base station or a wireless transceiver node. It should also be noted that the electronic device 100 may be implemented at the chip level, or may be implemented at the device level. For example, the electronic device 100 may work as a base station itself, and may also include external devices such as a memory, a transceiver (not shown in the figure), etc. The memory may be used to store programs and related data information that need to be executed by the base station to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, other base stations, etc.), and the implementation form of the transceiver is not specifically limited here.

[0032] The user equipment (UE) measures the downlink beam pair to be measured, for example, to obtain the reference signal received power (RSRP) or signal to interference plus noise ratio (SINR) of the received signal, etc. The acquisition unit 101 is configured to receive the measurement result from the UE and execute the AI ​​model on the network side.

[0033] The prediction unit 102 uses the measurement result as the input of the AI ​​model, and performs beam pair prediction by executing the AI ​​model to obtain a prediction output, which is, for example, the optimal downlink beam pair to be used for communication. In actual communication, due to reasons such as the rapid change frequency of the UE's moving direction, the change frequency of the optimal downlink receiving beam is often higher than the change frequency of the optimal downlink transmitting beam. That is, within the coverage range of a certain optimal downlink transmitting beam, the corresponding optimal downlink receiving beam will change multiple times. Therefore, the optimal downlink receiving beam will be frequently switched during the residence time of a certain optimal downlink transmitting beam. That is, the optimal downlink beam pair will change frequently. If the optimal downlink beam pair predicted output fails, the input required for the AI ​​model will be remeasured, which will increase the measurement and reporting overhead.

[0034] For ease of understanding, Figure 2 A schematic example is shown. Figure 2 In the example, there are 5 downlink transmit beams and 4 downlink receive beams. When performing beam measurement for beam management, the UE needs to measure a total of 20 beam pairs, corresponding to 20 RSRP values. When reporting the RSRP of the candidate beam pair and the corresponding ID, it can be done according to Table 1 below.

[0035] Table 1

[0036] RSRP value / difference Downlink transmit beam Downlink receive beam RSRP1(max) T3 R2 RSRP2 (difference) T3 R3 RSRP3 (difference) T4 R4 RSRP5(Difference) T2 R1

[0037] Among them, the downlink transmission beams corresponding to RSRP1 and RSRP2 are both T3, and their IDs are reported repeatedly. Assume that the AI ​​model predicts that the optimal beam pair is {T3, R2}, and the UE uses this beam pair for communication. When the UE moves, the optimal beam pair {T3, R2} becomes invalid, and the UE re-measures and reports, for example, there are possible changes as shown in Table 2 below.

[0038] Table 2

[0039] RSRP value / difference Downlink transmit beam Downlink receive beam RSRP1(max) T3 R3

[0040] At this time, the optimal downlink transmission beam is still T3, and the optimal downlink receiving beam becomes R3, which is equivalent to the switching of the optimal downlink receiving beam during the residence time of the optimal downlink transmission beam T3.

[0041] It is understandable that the switching of the optimal downlink receiving beam causes an increase in the UE's measurement and reporting overhead. In addition, in the AI ​​model-based beam management, if a field about the downlink receiving beam is added to the existing reporting mechanism, as the UE antenna capability expands and more downlink receiving beams are supported, the reporting overhead will increase significantly, and the frequent switching of the optimal downlink receiving beam will aggravate this situation.

[0042] In this embodiment, a solution is proposed to reduce the measurement and reporting overhead of the UE by improving the prediction output of the AI ​​model. Specifically, the prediction output includes an optimal downlink transmit beam, multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam, and the dwell time of each optimal downlink receive beam.

[0043] In other words, the predicted optimal downlink transmit beam and the optimal downlink receive beam are not necessarily one-to-one corresponding, and an optimal downlink transmit beam can correspond to multiple optimal downlink receive beams within its residence time in chronological order. That is, the optimal downlink transmit beam and multiple optimal downlink receive beams constitute an optimal beam pair in sequence according to their residence time. In this way, at least within the residence time of the optimal downlink transmit beam, re-measurement and prediction when the optimal downlink receive beam is switched can be avoided, thereby reducing overhead. Moreover, since the number of downlink transmit beams is much larger than the number of downlink receive beams, this method can also effectively reduce reporting overhead.

[0044] Figure 3A schematic example is shown. Tx#1 is the current optimal downlink transmit beam. During its residence time, the corresponding optimal downlink receive beams are Rx#1, Rx#2, Rx#3, and Rx#4, respectively. The prediction output of the AI ​​model may, for example, include the form of [Tx#1; Rx#1, Rx#2, Rx#3, Rx#4], where the field of each optimal downlink receive beam may also include information about its residence time. In this way, re-measurement, reporting, and prediction after the failure of the Tx#1 and Rx#1 beam pairs can be avoided, thereby reducing overhead.

[0045] like Figure 4 As shown, the electronic device 100 may further include a sending unit 103 configured to send the prediction output of the AI ​​model to the UE. The UE uses multiple optimal downlink beams in sequence according to the dwell time in the prediction output to receive the optimal downlink transmission beam.

[0046] The dwell time of the beam may be represented by a time period or a timestamp for transmitting the beam. In addition, the prediction output may also include the dwell time of the optimal downlink transmission beam. It should be understood that this is not restrictive.

[0047] In addition, each downlink beam pair to be measured may also be indicated in a similar manner, that is, each downlink beam pair to be measured may include one downlink transmit beam and a plurality of downlink receive beams corresponding to the one downlink transmit beam.

[0048] Correspondingly, the reporting format of the measurement results as the input of the AI ​​model can also be designed similarly. That is, one downlink transmit beam corresponds to multiple downlink receive beams, and the downlink transmit beam is not reported repeatedly, but the downlink receive beam can be reported repeatedly. For example, the following format can be adopted:

[0049] Set A{[Tx#1;Rx#1,Rx#2,…,Rx#n],[Tx#2;Rx#1,Rx#2,…,Rx#n],…,[Tx#m;Rx#1,Rx#2,…,Rx#n]};

[0050] Set B{[Tx#1;Rx#1,Rx#2,…,Rx#n],[Tx#2;Rx#1,Rx#2,…,Rx#n],…,[Tx#m;Rx#1,Rx#2,…,Rx#n]}.

[0051] Among them, Tx#1≠Tx#2≠…≠Tx#m.

[0052] Among them, Set A contains all possible beam sets and is considered a complete set; Set B contains the beam sets used as inputs for measuring the AI ​​model during inference. During the training phase, the data required by the AI ​​model comes from the measurement of SetA and / or Set B. When Set B is a subset of Set A, Set A needs to be measured; when Set A is different from Set B, Set A+Set B needs to be measured. During the inference phase, only the beams of Set B need to be measured.

[0053] Of course, this is not restrictive, and the indication method of the beam to be measured in the existing beam management and the input form of the existing AI model may also be adopted.

[0054] In addition, the acquisition unit 101 is further configured to acquire one or more of the following information: information related to the indication of the downlink beam pair corresponding to the measurement result, and information related to the movement of the UE. For example, the acquisition unit 101 receives this information from the UE.

[0055] The UE's mobility-related information may include, for example, one or more of the following: the UE's trajectory, the UE's speed, the UE's activity range, the UE's location, and the UE's moving direction. The AI ​​model may refer to the UE's mobility-related information to predict multiple optimal downlink receive beams within the optimal downlink transmit beam. In addition, the AI ​​model may also refer to the historical switching information of the downlink receive beam to predict multiple optimal downlink receive beams within the optimal downlink transmit beam.

[0056] In addition, in order to further reduce the reporting overhead or improve the data quality used for the AI ​​model, the obtained measurement results can be obtained by the UE filtering the measured data. For example, the UE can filter the data according to the quality of the measured data. The quality of the data can be represented by the physical layer RSRP and / or SINR of the measured signal.

[0057] As an example, the authentication information of the AI ​​model may include information related to screening. The information related to screening may include, for example, reference information for classifying data according to the quality of the measured data. The reference information may include, for example, one or more physical layer RSRP and / or SINR thresholds.

[0058] The UE may classify the data into data of different quality levels according to the reference information, wherein the UE adopts finer quantization precision and smaller step size for the data of higher quality level than the data of lower quality level. Furthermore, the UE may also discard the data of the lowest one or more quality levels.

[0059] For example, it can be considered that when the measured RSRP value is larger, the corresponding beam pair is closer to the optimal beam pair, so the data can be considered as high-quality data. Conversely, when the measured RSRP value is smaller, the corresponding beam pair is farther away from the optimal beam pair, and the data can be considered as low-quality data. It can be understood that the quantization accuracy of the data and the step size used when calculating the difference will affect the performance of the AI ​​model on the one hand, and determine the data overhead when reporting on the other hand.

[0060] According to this example, finer quantization accuracy and smaller step size are used for high-quality data, so as to control the data overhead during reporting while ensuring that the data quality required by the AI ​​model is met.

[0061] For example, for ease of understanding, an illustrative but non-restrictive example is given below. Assume that the reference information includes two RSRP thresholds th1 and th2, and th1 is greater than th2. When the measured RSRP is greater than th1, the corresponding data is quantized using the first quantization accuracy. If the difference is to be calculated, the first step length is used; when the measured RSRP is between th1 and th2, the corresponding data is quantized using the second quantization accuracy. If the difference is to be calculated, the second step length is used, wherein the first quantization accuracy is higher than the second quantization accuracy, and the first step length is smaller than the second step length; when the measured RSRP is less than th1, the corresponding data is discarded.

[0062] In the training phase of the AI ​​model, in order to ensure data traversal and diversity, all measured data can be used for training, but in the inference phase of the AI ​​model, in order to reduce reporting overhead, the above-mentioned filtering operation can be used. Of course, this is not restrictive, and data can also be filtered during the training phase.

[0063] In addition, when the UE performs data screening, there may be a situation where different downlink transmit beams correspond to different numbers of downlink receive beams. That is, for the reported [Tx#m; Rx#1, Rx#2, ..., Rx#n], when m is different, n may be different.

[0064] The authentication information of the AI ​​model is mentioned above, wherein the acquisition unit 101 and the sending unit 103 can be configured to share the authentication information of the AI ​​model with the UE, wherein the authentication information includes information related to the UE screening the measured data to obtain the measurement results.

[0065] The authentication information of the AI ​​model is transmitted, for example, during the authentication phase of the AI ​​model. The authentication of the AI ​​model is to align the network side and the UE's understanding of the AI ​​model, for example, including function-based authentication and model-based authentication. Function-based authentication is a description of the AI ​​model function, and model-based authentication is a description of the model, such as emphasizing the model ID or quantity.

[0066] In addition, when the model is monitored, the network side and the UE need to align their understanding of the predicted output. In this embodiment, the AI ​​model is deployed on the network side. Since the sending unit 103 sends the predicted output to the UE, the network side and the UE can align their understanding of the predicted output, and monitoring can be performed on both the network side and the UE side.

[0067] To sum up, according to this embodiment, the electronic device 100 obtains the optimal downlink transmit beam and multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam through beam pair prediction based on the AI ​​model, which can effectively reduce the measurement overhead and reporting overhead used for beam management.

[0068] <Second Embodiment>

[0069] In this embodiment, the electronic device 100 is located on the UE side, and the AI ​​model is executed by the UE. Among them, the UE can be various wireless communication terminals, or it can be a communication terminal such as a mobile base station. The electronic device 100 can be implemented at the chip level, or it can be implemented at the device level. For example, the electronic device 100 can work as the UE itself, and can also include external devices such as a memory and a transceiver (not shown). The memory can be used to store programs and related data information that the UE needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (for example, other UEs, base stations, core networks, etc.), and the implementation form of the transceiver is not specifically limited here.

[0070] In this case, the acquisition unit 101 locally acquires the measurement result and related information. The related information here includes, for example, one or more of the following: related information indicating the downlink beam pair corresponding to the measurement result, and UE mobility related information. The detailed description has been given in the first embodiment and will not be repeated here.

[0071] In addition, the relevant contents regarding prediction output and data screening described in the first embodiment are also applicable to this embodiment and subsequent embodiments, and will be appropriately simplified or omitted in the following description.

[0072] The optimal downlink transmit beam in the prediction output and the multiple optimal downlink receive beams sequentially form an optimal beam pair according to the dwell time, and the UE sequentially uses the multiple optimal downlink receive beams to receive the optimal downlink transmit beam according to the dwell time. Optionally, the prediction output may also include the dwell time of the optimal downlink transmit beam. The dwell time of the beam may be represented, for example, by a time period or a timestamp for transmitting the beam.

[0073] In the inference phase of the AI ​​model, the sending unit 103 sends the information of the optimal downlink transmit beam to the network side. Because the network side does not need to know which downlink receive beam the UE uses for reception, the sending unit 103 does not need to send the complete information of the predicted output to the network side, which can reduce the signaling overhead. The information of the optimal downlink transmit beam includes, for example, the ID of the corresponding beam, and may optionally include the dwell time of the corresponding beam.

[0074] On the other hand, in the monitoring phase of the AI ​​model, if the detection is performed on the network side, the sending unit 103 is configured to send the prediction output to the network side. This is because, in this case, the network side and the UE need to align their understanding of the prediction output.

[0075] In addition, the downlink beam pair to be measured and the input of the AI ​​model can also be configured or designed in a form similar to the form of the predicted output of the AI ​​model. Of course, this is not restrictive, and the existing indication method for the beam to be measured and the input form of the existing AI model can also be used.

[0076] As described in the first embodiment, each downlink beam pair to be measured may include a downlink transmit beam and multiple downlink receive beams corresponding to the downlink transmit beam. The acquisition unit 101 may, for example, receive an indication of the downlink beam pair from the network side. The input of the AI ​​model may also be designed similarly. That is, one downlink transmit beam corresponds to multiple downlink receive beams.

[0077] In addition, the measurement result used for the AI ​​model can be obtained by the UE screening the measured data. For example, the UE (specifically, the prediction unit 102 of the electronic device 100) can screen the data according to the quality of the measured data. The quality of the data can be represented by the physical layer RSRP and / or SINR of the measured signal.

[0078] As an example, the authentication information of the AI ​​model may include information related to screening. The information related to screening may include, for example, reference information for classifying data according to the quality of the measured data. The reference information may include, for example, one or more physical layer RSRP and / or SINR thresholds.

[0079] The UE may classify the data into data of different quality levels according to the reference information, wherein the UE adopts finer quantization precision and smaller step size for the data of higher quality level than the data of lower quality level. Furthermore, the UE may also discard the data of the lowest one or more quality levels.

[0080] The acquisition unit 101 and the sending unit 103 may be configured to share the authentication information of the AI ​​model with the network side, wherein the authentication information includes information related to the UE screening the measured data to obtain the measurement result. For the description of the AI ​​model authentication, please refer to the first embodiment.

[0081] To sum up, according to this embodiment, the electronic device 100 obtains the optimal downlink transmit beam and multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam through beam pair prediction based on the AI ​​model, which can effectively reduce the measurement overhead and reporting overhead used for beam management.

[0082] <Third Embodiment>

[0083] Figure 5 FIG. 4 shows a functional module block diagram of an electronic device 200 on a user equipment side for wireless communication according to this embodiment. Figure 5 As shown, the electronic device 200 includes: a sending unit 201, configured to send a measurement result for a downlink beam pair to be measured to a network side, wherein the downlink beam pair to be measured includes a downlink transmit beam and a downlink receive beam, and the network side performs beam pair prediction using an AI model based on the measurement result to obtain a prediction output, wherein the prediction output includes an optimal downlink transmit beam, multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam, and a residence time of each optimal downlink receive beam; and a receiving unit 202, configured to receive the prediction output from the network side.

[0084] The sending unit 201 and the receiving unit 202 may be implemented by one or more processing circuits, which may be implemented as a chip or a processor, for example. Figure 5 The various functional units in the electronic device shown in the figure are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation method.

[0085] The electronic device 200 is located on the UE side. Among them, the UE can be various wireless communication terminals, or it can be a communication terminal such as a mobile base station. The electronic device 100 can be implemented at the chip level, or it can also be implemented at the device level. For example, the electronic device 100 can work as the UE itself, and can also include external devices such as a memory and a transceiver (not shown). The memory can be used to store programs and related data information that need to be executed by the UE to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (for example, other UEs, base stations, core networks, etc.), and the implementation form of the transceiver is not specifically limited here.

[0086] In this embodiment, the AI ​​model is executed by the network side. The UE obtains the prediction output from the network side via the receiving unit 202. The optimal downlink transmit beam and the multiple optimal downlink receive beams sequentially constitute an optimal beam pair according to the dwell time, and the receiving unit 202 is configured to sequentially use the multiple optimal downlink receive beams to receive the optimal downlink transmit beam according to the dwell time. Optionally, the prediction output may also include the dwell time of the optimal downlink transmit beam.

[0087] In addition, the UE measures the downlink beam pair to be measured to provide input for the AI ​​model on the network side. Similar to the first embodiment, each downlink beam pair to be measured may include a downlink transmit beam and multiple downlink receive beams corresponding to one downlink transmit beam. The UE may, for example, receive an indication of the downlink beam pair from the network side. The input of the AI ​​model may also be similarly designed, that is, one downlink transmit beam corresponds to multiple downlink receive beams. Accordingly, the UE may also adopt a similar form when reporting the measurement results.

[0088] The sending unit 201 is also configured to send one or more of the following information to the network side: relevant information of the indication of the downlink beam pair corresponding to the measurement result, and relevant information of the UE's mobility.

[0089] The UE's mobility-related information may include, for example, one or more of the following: the UE's trajectory, the UE's speed, the UE's activity range, the UE's location, and the UE's moving direction. The AI ​​model may refer to the UE's mobility-related information to predict multiple optimal downlink receive beams within the optimal downlink transmit beam. In addition, the AI ​​model may also refer to the historical switching information of the downlink receive beam to predict multiple optimal downlink receive beams within the optimal downlink transmit beam.

[0090] In addition, in order to further reduce the reporting overhead or improve the data quality used for the AI ​​model, the obtained measurement results can be obtained by the UE filtering the measured data. Figure 6 As shown, the electronic device 200 may further include a screening unit 203, which is configured to obtain a measurement result by screening the data obtained by measurement. For example, the screening unit 203 is configured to screen the data by classifying the data according to the quality of the data obtained by measurement. The quality of the data can be represented by the physical layer RSRP and / or SINR of the measured signal, for example.

[0091] The reference information used for classification may be included in the authentication information of the AI ​​model, for example. The reference information may include one or more physical layer RSRP and / or SINR thresholds.

[0092] The screening unit 203 classifies the data into data of different quality levels according to the reference information. Compared with the data of the lower quality level, the screening unit 203 adopts finer quantization accuracy and smaller step size for the data of the higher quality level. Optionally, the screening unit 203 can be configured to discard the data of the lowest one or more quality levels. The specific examples have been given in the first embodiment and will not be repeated here.

[0093] The screening unit 203 may be configured to perform screening according to the capability of the UE. For example, if the UE does not have the capability to perform data screening, the screening unit 203 does not perform screening.

[0094] To summarize, according to the present embodiment, the electronic device 200 can avoid frequent switching of downlink receiving beams by obtaining the optimal downlink transmitting beam predicted by the beam pair based on the AI ​​model and multiple optimal downlink receiving beams corresponding to the optimal downlink transmitting beam, thereby effectively reducing the measurement overhead and reporting overhead used for beam management.

[0095] <Fourth Embodiment>

[0096] In the process of describing the electronic device for beam management in wireless communication and the electronic device on the user equipment side for wireless communication in the above embodiments, it is obvious that some processing or methods are also disclosed. In the following, an overview of these methods is given without repeating some of the details discussed above, but it should be noted that although these methods are disclosed in the process of describing the electronic device for beam management in wireless communication and the electronic device on the user equipment side for wireless communication, these methods do not necessarily adopt the components described or are not necessarily performed by those components. For example, the embodiments of the electronic device for beam management in wireless communication and the electronic device on the user equipment side for wireless communication can be partially or completely implemented using hardware and / or firmware, and the methods discussed below can be completely implemented by a computer-executable program, although these methods can also adopt the hardware and / or firmware of the electronic device for beam management in wireless communication and the electronic device on the user equipment side for wireless communication.

[0097] Figure 7 A flowchart of a method for beam management in wireless communication according to an embodiment of the present application is shown, the method comprising: obtaining a measurement result of a user equipment for a downlink beam pair to be measured (S11), the downlink beam pair to be measured comprising a downlink transmit beam and a downlink receive beam; and based on the measurement result, using an AI model to perform beam pair prediction to obtain a prediction output (S12), wherein the prediction output comprises an optimal downlink transmit beam, multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam, and a dwell time of each optimal downlink receive beam. The method can be performed on the network side or on the UE side.

[0098] For example, each downlink beam pair to be measured may include one downlink transmit beam and a plurality of downlink receive beams corresponding to the one downlink transmit beam.

[0099] In step S11, one or more of the following information may also be obtained: information related to the indication of the downlink beam pair corresponding to the measurement result, and information related to the movement of the UE. The information related to the movement of the UE may include, for example, one or more of the following: the trajectory of the UE, the speed of the UE, the activity range of the UE, the location of the UE, and the moving direction of the UE.

[0100] The prediction output may also include a dwell time of the optimal downlink transmit beam. The dwell time of the beam may be represented by a time period or a timestamp for transmitting the beam. The optimal downlink transmit beam and the multiple optimal downlink receive beams sequentially form an optimal beam pair according to the dwell time, wherein the UE sequentially uses the multiple optimal downlink receive beams to receive the optimal downlink transmit beam according to the dwell time.

[0101] In one example, the measurement result obtained is obtained by the UE filtering the data obtained by the measurement, wherein the authentication information of the AI ​​model includes information related to the filtering. The information related to the filtering includes reference information for classifying the data according to the quality of the data obtained by the measurement. The quality of the data can be represented by the physical layer RSRP and / or SINR of the measured signal, and the reference information includes one or more physical layer RSRP thresholds and / or SINR thresholds.

[0102] For example, the UE classifies the data into data of different quality levels according to the reference information, and the UE uses finer quantization precision and smaller step size for the data in the higher quality level than for the data in the lower quality level. Optionally, the UE may discard the data in the lowest one or more quality levels.

[0103] In the case where the method is executed on the network side, the method further includes: receiving a measurement result and the above information from a UE, and sending a prediction output to the UE.

[0104] The method also includes: sharing authentication information of the AI ​​model with the UE, the authentication information including information related to the UE screening the measured data to obtain the measurement result.

[0105] When the method is executed on the UE side, the method also includes: when model monitoring of the AI ​​model is performed on the network side, sending the prediction output to the network side; and in the inference stage of the AI ​​model, sending information of the optimal downlink transmission beam to the network side.

[0106] The method also includes: sharing authentication information of the AI ​​model with the network side, the authentication information including information related to the UE screening the measured data to obtain the measurement result.

[0107] The above method corresponds to the electronic device 100 in the first embodiment and the second embodiment. The relevant specific details can be referred to the first embodiment and the second embodiment, which will not be repeated here.

[0108] Figure 8 A flowchart of a method for wireless communication at the UE side according to an embodiment of the present application is shown, the method comprising: sending a measurement result for a downlink beam pair to be measured to the network side (S22), the downlink beam pair to be measured includes a downlink transmit beam and a downlink receive beam, the network side performs beam pair prediction using an AI model based on the measurement result to obtain a prediction output, wherein the prediction output includes an optimal downlink transmit beam, multiple optimal downlink receive beams corresponding to the optimal downlink transmit beam, and the dwell time of each optimal downlink receive beam; and receiving the prediction output from the network side (S23). The method can be performed on the UE side.

[0109] The optimal downlink transmission beam and the multiple optimal downlink receiving beams sequentially form an optimal beam pair according to the dwell time, such as Figure 8 As shown in a dotted box in , the method further includes step S24: using multiple optimal downlink receiving beams in sequence according to the dwell time to receive the optimal downlink transmitting beam.

[0110] In addition, in step S22, one or more of the following information may be sent to the network side: relevant information indicating the downlink beam pair corresponding to the measurement result, and information related to the mobility of the UE.

[0111] For example, each downlink beam pair to be measured includes one downlink transmit beam and a plurality of downlink receive beams corresponding to the one downlink transmit beam.

[0112] like Figure 8 As shown in another dotted line frame in FIG. 1 , the method may further include step S21: obtaining a measurement result by screening the measured data. For example, the screening may be performed by classifying the data according to the quality of the measured data.

[0113] For example, the authentication information of the AI ​​model includes reference information for classification. The quality of the data can be represented by the physical layer RSRP and / or SINR of the measured signal, and the reference information includes one or more physical layer RSRP thresholds and / or SINR thresholds.

[0114] Step S21 may include: classifying the data into data of different quality levels according to the reference information, using finer quantization precision and smaller step size for data in higher quality levels than for data in lower quality levels. Optionally, data in the lowest one or more quality levels may be discarded. The screening may be performed according to the capability of the UE.

[0115] The above method corresponds to the electronic device 200 in the third embodiment. The relevant specific details can be referred to the third embodiment and will not be repeated here.

[0116] Note that the above methods can be used in combination or individually.

[0117] The technology of the present disclosure can be applied to various products.

[0118] The electronic device 100 may also be implemented as various base stations. The base station may be implemented as any type of evolved Node B (eNB) or gNB (5G base station). eNBs include, for example, macro eNBs and small eNBs. Small eNBs may be eNBs that cover cells smaller than macro cells, such as pico eNBs, micro eNBs, and home (femto) eNBs. Similar situations may also apply to gNBs. Alternatively, the base station may be implemented as any other type of base station, such as a NodeB and a base transceiver station (BTS). The base station may include: a main body (also referred to as a base station device) configured to control wireless communications; and one or more remote radio heads (RRHs) arranged in a different place from the main body. In addition, various types of user equipment may work as a base station by temporarily or semi-permanently performing base station functions.

[0119] For example, the electronic devices 100 and 200 may be implemented as various user devices. The user device may be implemented as a mobile terminal (such as a smart phone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable / dongle-type mobile router, and a digital camera) or a vehicle-mounted terminal (such as a car navigation device). The user device may also be implemented as a terminal that performs machine-to-machine (M2M) communication (also referred to as a machine type communication (MTC) terminal). In addition, the user device may be a wireless communication module (such as an integrated circuit module including a single chip) installed on each of the above-mentioned terminals.

[0120] [Application examples for base stations]

[0121] (First application example)

[0122] Fig. 9800 is a block diagram showing a first example of a schematic configuration of an eNB or gNB to which the technology of the present disclosure can be applied. Note that the following description takes eNB as an example, but can also be applied to gNB. The eNB 800 includes one or more antennas 810 and a base station device 820. The base station device 820 and each antenna 810 can be connected to each other via an RF cable.

[0123] Each of the antennas 810 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for the base station device 820 to transmit and receive wireless signals. Fig. 9 As shown, the eNB 800 may include multiple antennas 810. For example, the multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Fig. 9 An example is shown in which the eNB 800 includes a plurality of antennas 810 , but the eNB 800 may also include a single antenna 810 .

[0125] The controller 821 may be, for example, a CPU or a DSP, and operates various functions of the higher layers of the base station device 820. For example, the controller 821 generates a data packet based on the data in the signal processed by the wireless communication interface 825, and transmits the generated packet via the network interface 823. The controller 821 may bundle data from a plurality of baseband processors to generate a bundled packet, and transmit the generated bundled packet. The controller 821 may have a logical function to perform the following control: the control may be such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control may be performed in conjunction with a nearby eNB or core network node. The memory 822 includes a RAM and a ROM, and stores programs executed by the controller 821 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

[0126] The network interface 823 is a communication interface for connecting the base station device 820 to the core network 824. The controller 821 can communicate with the core network node or another eNB via the network interface 823. In this case, the eNB 800 and the core network node or other eNBs can be connected to each other through a logical interface (such as an S1 interface and an X2 interface). The network interface 823 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line. If the network interface 823 is a wireless communication interface, the network interface 823 can use a higher frequency band for wireless communication compared to the frequency band used by the wireless communication interface 825.

[0127] The wireless communication interface 825 supports any cellular communication scheme (such as long term evolution (LTE) and LTE-Advanced), and provides a wireless connection to a terminal located in a cell of the eNB 800 via an antenna 810.

Instead of the controller 821, the BB processor 826 may have a part or all of the above-mentioned logical functions. The BB processor 826 may be a memory storing a communication control program, or a module including a processor configured to execute a program and related circuits. Updating the program may change the function of the BB processor 826. The module may be a card or a blade inserted into a slot of the base station device 820. Alternatively, the module may also be a chip mounted on a card or a blade. Meanwhile, the RF circuit 827 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives a wireless signal via the antenna 810 .

[0128] like Fig. 9 As shown, the wireless communication interface 825 may include multiple BB processors 826. For example, the multiple BB processors 826 may be compatible with multiple frequency bands used by the eNB 800. Fig. 9 As shown, the wireless communication interface 825 may include multiple RF circuits 827. For example, the multiple RF circuits 827 may be compatible with multiple antenna elements. Fig. 9 An example is shown in which the wireless communication interface 825 includes a plurality of BB processors 826 and a plurality of RF circuits 827 , but the wireless communication interface 825 may also include a single BB processor 826 or a single RF circuit 827 .
