Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0185] In some embodiments, for example, when the communication frequency band is in frequency range 2, since high-frequency channels attenuate quickly, beam-based transmission and reception are required to ensure coverage.

[0186] In some embodiments, the base station configures a reference signal resource set for beam measurement. The terminal measures the reference signal resources in the reference signal resource set and then reports the X strongest reference signal resource identifiers (IDs) and the corresponding L1-RSRP and / or L1-SINR. The problem with this is that the reference signal resource set configured by the base station contains X reference signals, each of which corresponds to a different transmit beam of the base station. For each reference signal, the terminal needs to use all receive beams to measure the reference signal, obtain the beam measurement quality corresponding to all receive beams, and determine the best beam measurement quality. Therefore, the number of beam pairs that the terminal needs to measure is M*N, where M is the number of transmit beams of the base station and N is the number of receive beams of the terminal. This results in excessive computational complexity and high latency.

[0187] In this regard, some embodiments of the present disclosure propose that an AI model can be used to obtain beam information.

[0188] For spatial prediction: the terminal measures the L1-RSRP of set B (which may also include the beam or beam pair ID), inputs it into the AI ​​model, and predicts the L1-RSRP of set A.

[0189] Optionally, the relationship between set B and set A includes the following two types:

[0190] 1. Set B is a subset of set A. For example, if set A contains 32 reference signals (each reference signal corresponds to a beam direction), then set B contains N of them, for example, N = 8. The above only considers the transmit beam.

[0191] If beam pairs are considered, the terminal's receive beams also need to be considered. For example, if there are 32 transmit beams and the terminal has 4 receive beams, then set A is 32*4 beam pairs; set B can be 32 beam pairs, or 16 beam pairs, and so on.

[0192] 2. Set B is a wide beam, and set A is a narrow beam. For example, set A contains 32 reference signals (each reference signal corresponds to a beam direction, and the 32 reference signals cover a 120-degree direction). Set B contains another N reference signals, for example, N = 8, and these N reference signals also cover a 120-degree direction. That is, the beam direction of each reference signal in set B covers the beam directions of multiple reference signals in set A. This can be understood as the relationship between the 32 / N reference signals in set A and the same reference signal in set B being QCL (quasi co-location) Type D.

[0193] In some of the following embodiments, set A may also be referred to as the second beam set, and set B may also be referred to as the first beam set.

[0194] In some embodiments, if there is no need to monitor the performance of the AI ​​model, assuming that the AI ​​model has been trained in advance, the base station only needs to periodically send the reference signal of set B (for example, the first period), and then the terminal measures the L1-RSRP of the reference signal in set B and inputs it into the AI ​​model, and then outputs the L1-RSRP of all beams or beam pairs of set A or the strongest X reference signal IDs or beam pair IDs among the 32 reference signals in the set.

[0195] In some embodiments, if it is necessary to monitor the performance of the AI ​​model, in addition to sending set B, the base station is also required to periodically send the reference signal of set A (for example, the second period, which can be greater than the first period. Whether it is a multiple of the first period or how much greater than the first period is not restricted here). Then, the terminal only measures the results of set B and inputs them into the AI ​​model to obtain the predicted beam information and report it to the base station. At the same time, it also measures the L1-RSRP of all reference signals in set A and obtains the beam information as the beam information obtained by the traditional method and reports it to the base station. Among them, if set B is a subset of set A, it is equivalent to the terminal only needing to measure all beams or beam pairs of set A.

[0196] In some embodiments, for time-domain prediction, the terminal measures the L1-RSRP at a historical time, set B, and inputs this into an AI model to predict the L1-RSRP at a future time, set A. In addition to the two aforementioned relationships between set B and set A, there is also a relationship where set B and set A are identical. Optionally, if the AI ​​model is used, reference signals for future time points can be omitted. Instead, beam information is obtained based on the AI ​​model output and reported to the base station.

[0197] In some embodiments, reference signals for future time points also need to be transmitted. The terminal measures these reference signals and obtains beam information, which is then reported to the base station. Therefore, during model performance monitoring, as with spatial beam prediction, the base station periodically transmits the transmit beams in set B and set A, and the terminal measures all beams or beam pairs in set B and set A.

[0198] Based on the AI ​​model, for example, the terminal originally needs to measure a total of M*N beam pairs (where M is the number of beams transmitted by the base station and N is the number of beams received by the terminal). However, thanks to the AI ​​model, for spatial beam prediction, the terminal only needs to measure a portion of the M*N beam pairs, such as 1 / 8, 1 / 4, etc., and then input the measured beam measurement quality of these beam pairs into the AI ​​model, and the model can output the beam information of the M*N beam pairs. For time domain beam prediction, the terminal can measure the beam quality of beam pairs at historical times to predict the beam information of beam pairs at future times. Of course, the input and output of the model do not consider the beam quality or beam ID of the beam pair, but only consider the beam quality or beam ID of the downlink transmit beam, that is, the AI ​​model is based on the downlink beam, not the AI ​​model based on the beam pair.

[0199] However, AI models have a lifecycle or a specific scope of application. For example, some models are suitable for suburban environments, some for urban areas, some for indoor environments, some for rush hour, and some for commuting during less crowded hours. Therefore, it is necessary to monitor the performance of AI models in real time. If the AI ​​model performance is poor, it is necessary to update or switch the AI ​​model.

[0200] In some embodiments, for the network-side model, when the network side performs monitoring, the content reported by the terminal may include the following two parts of data: one part of the data is used as the input of the network-side model, such as the RSRP of the beam (pair) in set B used for model input, or the RSRP of the beam (pair) and the ID of the corresponding beam (pair); the network side obtains the predicted best N beam (pair) IDs and / or RSRPs of set A based on the input of set B. The RSRP output here may be the RSRP corresponding to one or more beams in set A. The other part of the data includes the best N beam (pair) IDs and / or RSRPs in set A actually measured by the terminal. The measured RSRP here may be the RSRP corresponding to one or more beams in set A.

[0201] In some embodiments, for the terminal-side model, when the network side monitors, the content reported by the terminal includes the following two parts of data: one part of the data is the output of the UE-side model, such as the RSRP of the beam (pair) in set A output by the model, and / or the ID of the beam (pair); that is, the predicted beam information of set A output by the model. The other part of the data includes the IDs and / or RSRPs of the best N beams (pairs) in set A actually measured by the terminal, that is, the measured beam information of set A actually measured.

[0202] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0203] Step S2101: The network device sends fourth information to the terminal.

[0204] In some embodiments, the fourth information is used to indicate a value of L. Optionally, L is used to indicate a maximum number of first sample data sent by the terminal. Wherein, L can be a positive integer.

[0205] In some embodiments, step S2101 is optional, and the terminal may independently determine the value of L. Alternatively, the value of L may be a value pre-agreed upon in a protocol. Alternatively, the value of L may be determined based on the number of second sample data in the third report sent in step S2103.

[0206] In some embodiments, the terminal receives fourth information sent by the network device. Optionally, the terminal determines the value of L based on the fourth information.

[0207] In some embodiments, the terminal determines L according to the number of second sample data in the third report. Optionally, the terminal determines L preset by the protocol.

[0208] In some embodiments, the fourth information may be referred to as “quantity indication information”, “sample quantity indication”, etc., and the embodiments of the present disclosure do not limit its name.

[0209] Step S2102: The terminal sends a second report to the network device.

[0210] In some embodiments, the second report includes the first data. Optionally, the first data is data related to AI model derivation. Optionally, the AI ​​model derivation-related data may include data input to the AI ​​model or data output by the AI ​​model.

[0211] In some embodiments, the AI ​​model is used to predict beam information for beams and / or beam pairs.

[0212] For example, based on the AI ​​model, the terminal can reduce the number of beams and / or beam pairs that need to be measured in the spatial domain, or the terminal can reduce the number of actual measurements of beams and / or beam pairs in the time domain.

[0213] In some embodiments, the AI ​​model is used for spatial beam prediction, wherein the terminal can measure some beams in the spatial domain and predict the beam information of other beams. Optionally, the AI ​​model is used to predict the beam information of the second beam set based on the actual measurement results for the first beam set. Optionally, the AI ​​model can predict the beam information of the second beam set corresponding to a time instance, such as the actual measurement results for the first beam set corresponding to the time instance (measurement time instance), for example, predict the beam information of the second beam set corresponding to the prediction time instance corresponding to the measurement time instance, wherein the prediction time instance and the measurement time instance are the same time instance.

[0214] For example, the terminal can measure the beams and / or beam pairs in the first beam set at a certain time instance, obtain actual measurement results, and input the actual measurement results into the AI ​​model to obtain beam information of the beams and / or beam pairs in the second beam set corresponding to the time instance.

[0215] In some embodiments, the AI ​​model is used for time-domain beam prediction, where the terminal can measure the beam quality of beams and / or beam pairs at historical times to predict beam information of beams and / or beam pairs at future times. Optionally, the AI ​​model is used to predict beam information corresponding to M predicted time instances for a second beam set based on actual measurement results for a first beam set corresponding to N historical measurement time instances. Where N and M are both integers greater than or equal to 1.

[0216] It can be understood that the values ​​of N and M can be equal or different. For example, N can be greater than M, or N can be less than M. The embodiments of the present disclosure do not limit this. In addition, the values ​​of N and M can be set based on the prediction effect of the AI ​​model. For example, they can be set to N=3 and M=2. The embodiments of the present disclosure do not limit this.

[0217] For example, the terminal can measure the beams and / or beam pairs in the first beam set at N measurement time instances before the current moment and obtain N actual measurement results, and input these N actual measurement results into the AI ​​model to obtain the beam information corresponding to the AI ​​model for the beams and / or beam pairs in the second beam set at M predicted time instances.

[0218] In some embodiments, the first beam set and the second beam set satisfy a preset condition. Optionally, the preset condition includes at least one of the following: the first beam set and the second beam set are the same; the first beam set is a subset of the second beam set; or the first beam set is a wide beam and the second beam set is a narrow beam corresponding to the first beam set.

[0219] For example, when only transmit beams are considered, the second beam set (set A) may include 32 reference signals, each corresponding to a beam direction, and the first beam set (set B) may include Q reference signals, for example, Q = 8. When beam pairs are considered, if the terminal corresponds to 4 receive beams, set A may include 32*4 beam pairs, and set B may include 32 beam pairs in set A, or 16 beam pairs, and so on.

[0220] Alternatively, the first beam set may be a wide beam, and the second beam set may be a narrow beam corresponding to the first beam set. The second beam set may include 32 reference signals, each of which corresponds to a beam direction, and the 32 reference signals cover a 120-degree direction. The first beam set may include Q reference signals, for example, Q = 8, and these 8 reference signals may also cover a 120-degree direction. That is, the beam direction of each reference channel in the second beam set covers the beam directions of multiple reference signals in the first beam set. The 32 / Qth reference signal in the second beam set is in a quasi-co-location (QCL) Type D relationship with the same reference signal in the second beam set.

[0221] In some embodiments, the AI ​​model is deployed on a terminal, and the first data is data output by the AI ​​model. Alternatively, the AI ​​model is deployed on a network device, and the first data is data input to the AI ​​model.

[0222] Optionally, when the AI ​​model is deployed on a network device, the first data may include the RSRP of the beam (pair) in the first beam set used for model input, or the RSRP of the beam (pair) and the ID of the corresponding beam (pair). Optionally, when the AI ​​model is deployed on a terminal, the first data includes the RSRP of the beam (pair) in the second beam set output by the model, and / or the ID of the beam (pair).

[0223] Among them, when the AI ​​model is deployed on the terminal, the terminal can use the AI ​​model to predict the beam information and obtain the data output by the AI ​​model. When the AI ​​model is deployed on the network device, the terminal needs to send the data input by the AI ​​model to the network device, so that the network device can use the AI ​​model to predict the beam information to obtain the data output by the AI ​​model.

[0224] It is understandable that when the AI ​​model is used for spatial beam prediction, the input data of the AI ​​model may be the actual measurement results for the first beam set, such as the timing measurement results of the first beam set corresponding to a time instance, and the output data of the AI ​​model may be the predicted beam information of the second beam set, such as the beam information of the second beam set corresponding to the time instance. When the AI ​​model is used for time-domain beam prediction, the input data of the AI ​​model may be the actual measurement results of the first beam set corresponding to N historical measurement time instances, and the output data of the AI ​​model may be the predicted beam information of the second beam set corresponding to M predicted time instances.

[0225] In some embodiments, the terminal may send the second report based on the UCI. Alternatively, the terminal may send the second report based on the UCI via the PUCCH or the PUSCH.

[0226] In some embodiments, the terminal may use at least one UCI to send the second report. When multiple UCIs are used to send the second report, the information carried by each UCI may be part of the second report or the first data. For example, one UCI may include one first sample data.

[0227] In some embodiments, the second report includes X first sample data, where the first sample data is a sample corresponding to the first data. Alternatively, the first data may be composed of X first sample data. Alternatively, the first sample data is a subset of the first data.

[0228] In some embodiments, an AI model is used for spatial beam prediction and is deployed on a network device. The first sample data includes actual measurement results for a first beam set, such as actual measurement results for the first beam set corresponding to a time instance. The first sample data is input data to the AI ​​model.

[0229] In some embodiments, an AI model is used for spatial beam prediction and is deployed on a terminal. The first sample data includes predicted beam information for a second beam set, such as beam information corresponding to the second beam set at a time instance. The first sample information is data output by the AI ​​model.

[0230] In some embodiments, an AI model is used for time-domain beam prediction and is deployed on a network device, and the first sample data includes actual measurement results for a first beam set corresponding to N historical measurement time instances. The first sample data is input data to the AI ​​model.

[0231] In some embodiments, the AI ​​model is used for time-domain beam prediction and is deployed on a terminal, and the first sample data includes predicted beam information corresponding to M prediction time instances. The first sample data is data output by the AI ​​model.

[0232] For example, the second report or the first data may include X groups of actual measurement results for the first beam set corresponding to historical measurement time instances, where one group of actual measurement results may include actual measurement results for the first beam set corresponding to N historical measurement time instances, and the first sample data may be actual measurement results for the first beam set corresponding to one group of these historical measurement time instances, where N is a positive integer.

[0233] Alternatively, the second report or the first data may include actual measurement results for the first beam set corresponding to X time instances, and the first sample data may be the actual measurement result for the first beam set corresponding to one of the time instances, where X is a positive integer.

[0234] In some embodiments, the terminal sends the second report using at least one UCI, where each UCI includes one first sample data and / or first information. Optionally, the terminal sends the second report using X UCIs.

[0235] In some embodiments, the first information is used to indicate that the first sample data included in the UCI is the i-th first sample data among X first sample data, where i is a positive integer. Optionally, the first information is used to indicate the index i corresponding to the first sample data included in the UCI, where i is 0 or a positive integer.

[0236] In some embodiments, i can be used to indicate that the corresponding first sample data is the i-th first sample data among X first sample data, or to indicate the index of the corresponding first sample data. For example, the network device can determine whether the corresponding second sample data is received based on i.

[0237] That is, when i represents the number corresponding to the first sample data, it can start from 1 and take values ​​upwards, and when i represents the index corresponding to the first sample data, it can start from 0 and take values ​​upwards.

[0238] In some embodiments, the network device receives a second report. Optionally, the network device receives a second report sent using at least one UCI. Optionally, the network device receives a second report sent using X UCIs, each UCI including a first sample data and / or first information.

[0239] In some embodiments, the terminal determines that the number i corresponding to the first sample data in the currently transmitted UCI reaches L, and sets i corresponding to the first sample data in the next UCI transmitted by the terminal to 1.

[0240] In some embodiments, the terminal determines that the index i corresponding to the first sample data in the currently transmitted UCI reaches L-1, and sets the index i corresponding to the first sample data in the next UCI transmitted by the terminal to 0.

[0241] In some embodiments, the network device may determine, based on the first information, whether each UCI sent by the terminal and the corresponding first sample data and / or second sample data are received.

[0242] In some embodiments, the second report may also be referred to as “model derivation data”, “model derivation report”, etc. The present disclosure does not limit the name of the second report.

[0243] Step S2103: The terminal sends a third report to the network device.

[0244] In some embodiments, the third report includes second data. Optionally, the second data includes actual measurement data corresponding to the data output by the AI ​​model. The data output by the AI ​​model may be the first data, or data obtained by the network device based on the first data. For example, the first data is the data input to the AI ​​model, and the network device may obtain the corresponding data output by the AI ​​model based on the first data.

[0245] Optionally, when the AI ​​model is deployed on the network device, the second data may include the best N beam (pair) IDs and / or RSRPs in the second beam set actually measured by the terminal, where the RSRP measured here may be the RSRP corresponding to one or more beams in set A. Optionally, when the AI ​​model is deployed on the terminal, the second data may include the best N beam (pair) IDs and / or RSRPs in the second beam set actually measured by the terminal, where the RSRP measured here may be the RSRP corresponding to one or more beams in set A.

[0246] For example, if the AI ​​model is deployed on a network device, the first data includes the data input to the AI ​​model, such as the actual measurement results of the first beam set corresponding to one or more time instances (such as the measurement time instance). The data output by the AI ​​model can include the beam information of the second beam set corresponding to these one or more time instances (such as the predicted time instance corresponding to the measurement time instance). Accordingly, the second data can include the actual measurement results of the second beam set corresponding to these one or more time instances. In the case of spatial beam prediction, the predicted time instance and the measured time instance are the same time instance.

[0247] In some embodiments, the terminal may send the third report based on RRC or MAC CE. Alternatively, the terminal may send the third report through PUSCH based on RRC or MAC CE.

[0248] In some embodiments, the third report includes Y second sample data, where the second sample data is a sample corresponding to the second data. Optionally, Y is less than or equal to X.

[0249] In some embodiments, the second data may be composed of Y second sample data. Optionally, the second sample data is a subset of the second data.

[0250] In some embodiments, the AI ​​model is used for spatial beam prediction and is deployed on a network device, and the second sample data includes actual measurement results for the second beam set, such as actual measurement results for the second beam set corresponding to a time instance.

[0251] In some embodiments, the AI ​​model is used for spatial beam prediction and is deployed on the terminal, and the second sample data includes actual measurement results for the second beam set, such as actual measurement results for the second beam set corresponding to a time instance.

[0252] In some embodiments, the AI ​​model is used for time-domain beam prediction and is deployed on a network device, and the second sample data includes actual measurement results for the second beam set corresponding to M prediction time instances.

[0253] In some embodiments, the AI ​​model is used for time-domain beam prediction and is deployed on the terminal, and the second sample data includes actual measurement results corresponding to M prediction time instances.

[0254] In some embodiments, the third report includes L second sample data. Optionally, the L second sample data correspond to the first sample data in the second report in sequence according to a preset order.

[0255] Optionally, the preset order can be, for example, the order of time from near to far or from far to near when the terminal sends the first sample data. For example, when using multiple UCIs to send the second report, the first sample data corresponds one-to-one with the second sample data in the third report according to the size of the corresponding i, such as the index corresponding to the first sample data or the corresponding number.

[0256] For example, when the first sample data most recently sent by the terminal is the predicted beam information for the second beam set corresponding to the time instance P or the actual measurement result for the first beam set, and the first second sample data in the third report can correspond to the first sample data, that is, the second sample data can be the actual measurement result for the second beam set corresponding to the time instance P, and the second first second sample data in the third report can correspond to the sample data sent by the terminal before sending the above-mentioned first sample data, such as the time instance P-1.

[0257] In some embodiments, the third report includes third information. Optionally, the third information is used to indicate the number of second sample data in the third report, where the second sample data corresponds to the first sample data in the second report in a predetermined order. Optionally, the third information includes L bits, each bit being used to indicate whether the third report includes the second sample data corresponding to the bit.

[0258] For example, when the third information indicates that the number of second sample data in the third report is J, these J second sample data may correspond to the J first sample data most recently sent by the terminal, for example, the J first sample data with the largest corresponding i value, that is, the first sample data sent earliest by the terminal has the lowest priority.

[0259] Alternatively, if the value of L is 4, when the third information is 1001, it may indicate that the third report only includes the second sample data corresponding to L-1 or the Lth first sample data and the second sample data corresponding to L-4 or the L-3th first sample data. For example, the L-1 or Lth first sample data may be the first sample data most recently sent by the terminal to the network device, and the L-4 or L-3th first sample data may be the first sample data earliest sent by the terminal to the network device.

[0260] In some embodiments, the third information may be the least significant bit in the third report. For example, if the third report includes at most K second sample data, the first bit of the third report may be the least significant bit in the third report. bits can be used to indicate the actual number of second sample data in the third report. Alternatively, the first L bits in the third report can be used to indicate whether the third report includes the second sample data corresponding to each of the L first sample data in the second report.

[0261] In some embodiments, the terminal determines that the number of second sample data that has been sent reaches L, and sets the number i corresponding to the next UCI to be sent to 1 or the index i to 0. Optionally, after sending the third report, the terminal sets the number i corresponding to the next UCI to be sent to 1 or the index i to 0.

[0262] In some embodiments, the network device receives a third report. Optionally, the network device determines the number of second sample data based on the third information. Optionally, the network device determines, based on the third information, whether the third report includes the second sample data corresponding to each first sample data. Optionally, the network device determines the first sample data corresponding to each of the L second sample data. Optionally, the network device determines, based on the third information, the first sample data corresponding to each of the at least one second sample data.

[0263] In some embodiments, after receiving the third report, the network device executes at least one of step S2104 and step S2105.

[0264] In some embodiments, the third aspect may also be referred to as “actual measurement data”, “real data information”, etc., and the present disclosure does not limit its name.

[0265] In some embodiments, the third information may also be referred to as “quantity indication information”, “actual measurement data indication information”, etc., and the embodiments of the present disclosure do not limit the names thereof.

[0266] Step S2104: The network device sends second information to the terminal.

[0267] In some embodiments, the second information is used to indicate that the network device has received L first sample data and / or second sample data. Optionally, the second information is used to instruct the terminal to set the number i corresponding to the next sent UCI to 1 or the index i to 0.

[0268] For example, the network device may send the second information to the terminal after receiving L first sample data.

[0269] For example, the network device may send the second information to the terminal after receiving L second sample data.

[0270] For example, the network device may send the second information to the terminal after receiving L first sample data and second sample data corresponding to the L first sample data.

[0271] In some embodiments, the second information may be sent by the network device after receiving the third report. Optionally, the second information may be HARQ ACK information for PUSCH.

[0272] In some embodiments, the terminal receives the second information. Optionally, the terminal determines that the second information has been received, and sets the number i corresponding to the next UCI to be sent to 1 or the index i to 0.

[0273] In some embodiments, step S2104 is optional. For example, the terminal may independently determine whether to set the number i corresponding to the next transmitted UCI to be 1 or the index i to be 0.

[0274] In some embodiments, the second information may also be called "data response information", "data confirmation information", etc., and the present disclosure does not limit its name.

[0275] Step S2105: The network device sends fifth information to the terminal.

[0276] In some embodiments, the fifth information is used to indicate activation or deactivation of an AI model. Optionally, the fifth information may include one bit, the value of which may be used to instruct the terminal to activate or deactivate the AI ​​model. Optionally, the fifth information is used to instruct the network device to deactivate a previously used AI model. Optionally, the fifth information is used to indicate the currently activated AI model of the network device.

[0277] For example, the fifth information may include one bit. When the AI ​​model is deployed on a terminal and the value of the bit is 1, it can be used to instruct the terminal to activate the AI ​​model or maintain the activation state of the AI ​​model. When the value of the bit is 0, it can be used to instruct the terminal to deactivate the AI ​​model or not activate the AI ​​model. Alternatively, when the AI ​​model is deployed on a network device and the value of the bit is 0, the bit can be used to instruct the network device to deactivate the currently used AI model. When the value of the bit is 1, it can be used to instruct the network device to activate and use the AI ​​model.

[0278] In some embodiments, the first data and the second data are used to monitor the performance of the AI ​​model. Optionally, the fifth information is determined based on the first data and the second data. Optionally, the network device sends the fifth information to the terminal based on the first data and the second data.

[0279] In some embodiments, the network device determines a performance metric corresponding to the AI ​​model based on the first data and the second data, and sends corresponding fifth information based on the performance metric.

[0280] For example, if the AI ​​model is the beam prediction model currently used by the terminal, and the first data is the data output by the AI ​​model, the network device can compare the received first data (for example, the first sample data in the second report) with the second data (for example, the corresponding second sample data in the third report) to determine whether the beam information output by the AI ​​model is accurate, and then determine whether to keep the AI ​​model activated or deactivate the AI ​​model, and send the corresponding fifth information.

[0281] Alternatively, if the AI ​​model is a candidate beam prediction model for the network device and the first data is data input to the AI ​​model, the network device can first input the first data into the AI ​​model and obtain the beam information output by the AI ​​model, and compare it with the received second data to determine whether the beam information output by the AI ​​model is better than the currently used AI model, and then determine whether to activate the candidate AI model, and deactivate the currently used AI model, and send the corresponding fifth information to enable the terminal to know the AI ​​model currently used by the network device.

[0282] In some embodiments, the fifth information may also be referred to as "model indication information", "deactivation indication information", etc., which is not limited in the embodiments of the present disclosure.

[0490] FIG5 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG5 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0493] In some embodiments, the above method may include the method described in the above terminal side, network device side, etc. embodiments, which will not be repeated here.

[0494] FIG6 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG5 , the present disclosure embodiment relates to a communication method, which includes:

[0495] In step S6101, the terminal sends AI model derivation related data and actual measurement data.

[0496] In some embodiments, the AI ​​model derivation-related data includes data input to the AI ​​model or data output by the AI ​​model, and the actual measurement data includes actual measurement results corresponding to the data output by the AI ​​model.

[0497] Optionally, if the model is on the terminal side, the data related to the AI ​​model deduction is the data output by the AI ​​model, that is, the output of the AI ​​model on the terminal side, that is, the prediction information of set A

[0498] Optionally, if the model is on the terminal side, the data related to the AI ​​model deduction is the data input to the AI ​​model (measurement information of set B), that is, the terminal side sends the input data for the AI ​​model to the network, and the network obtains the output of the AI ​​model based on the AI ​​model, that is, the prediction information.

[0499] In some embodiments, the terminal may send AI model derivation related data and actual measurement data in either of the following two ways.

[0500] Method 1: The terminal can send the AI ​​model-derived data and actual measurement data in one report.

[0501] For example, for an inactive model, since it has not yet been used for prediction, the data related to AI model derivation does not need to be sent as promptly. That is, it can be sent together with the actual measurement data used for performance monitoring. Multiple samples can be sent together, each sample including a set of model derivation-related data and a set of actual measurement data. For example, it can be sent via PUSCH based on RRC signaling or MAC CE.

[0502] For example, the report format is:

[0503] Sample #1: The first set of model-derived data and the first set of actual measured data;

[0504] Sample #2: The second set of model-derived data and the second set of actual measured data;

[0505] Sample#2: The second set of model-derived data and the second set of actual measured data.

[0506] It should be noted that, in the case of spatial beam prediction, a set of data (eg, a sample) corresponds to a measurement time instance.

[0507] In some embodiments, if the model derivation related data is the model input data, then a set of data includes the measurement results of set B and the measurement results of set A at a measurement time instance.

[0508] In some embodiments, if the model-derived related data is model output data, then a set of data includes a prediction result of set A and a measurement result of set A for a measurement time instance.

[0509] In some embodiments, for time-domain beam prediction, prediction results of M predicted future time instances are obtained based on measurement results of N history measurement time instances.

[0510] In some embodiments, if the model-derived related data is the model input data, then a set of data includes set B measurement results of N history measurement time instances and set A measurement results of M predicted future time instances.

[0511] In some embodiments, if the model-derived related data is model output data, then a set of data includes prediction results of set A of M predicted future time instances and measurement results of set A of M predicted future time instances.

[0512] In some embodiments, if the model is active, the latency requirement for the model derivation-related data is very high, and it can be sent based on the beam measurement report fed back by the traditional Channel State Information (CSI). For example, each transmission includes only one sample of data, and each sample includes a set of model derivation-related data and actual measurement results. Optionally, due to the high latency requirement, this can be sent through the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH) based on UCI.

[0513] Method 2: The terminal sends the AI ​​model-derived data and actual measurement data in different reports.

[0514] For example, for an active model, data related to model derivation has high latency requirements and can be sent based on UCI. Actual measurement results are used for performance monitoring and have less stringent latency requirements, so they can be sent based on RRC signaling or MAC CE. These two can be sent separately. When sending them separately, how can we indicate the one-to-one correspondence between actual measurement results and model derivation-related data?

[0515] Specifically, in some embodiments, for data related to model derivation, when each model derivation related data is sent, a total of L samples uploaded are attached, which also means that the current one is the Lth one. If the network device only receives L-4 and L-1, it means that the middle L-3 and L-2 were not successfully received by the network side.

[0516] In some embodiments, the maximum value of L is configured by the network or specified by the protocol. After the actual measurement results corresponding to L samples are sent or successfully received by the network, for example, the network sends a hybrid automatic repeat-request (HARQ) acknowledgment (ACK) message for the PUSCH, the value of L is reset to 1.

[0517] In some embodiments, the maximum value of L may also correspond to the number of actual measurement results included in a report.

[0518] In some embodiments, after uploading L model-derived data, the terminal uploads a report containing actual measurement data corresponding to multiple model-derived data, and the lowest bit in this report will indicate how many samples correspond to the actual measurement data reported. Subsequently, the actual measurement data corresponding to each sample is given in order from the most recent to the oldest sample (or vice versa).

[0519] In some embodiments, the least significant bit indicates how many samples of actual measurement data are reported. This may include at least one of the following three indication methods:

[0520] 1. Only the number of samples is indicated, and these samples correspond to L samples and go forward in sequence, that is, the actual measurement data corresponding to the first sample has the lowest sending priority.

[0521] 2. There are L bits, one for each sample. "1" indicates that the sample has actual measurement data sent, and "0" indicates that it does not.

[0522] 3. If this bit is not set, all L messages will be sent by default.

[0523] In some embodiments, after receiving the one-to-one correspondence between the model derivation related data and the actual measurement data, the network device obtains the performance metric, determines whether the model (or functionality) is active or deactive, and then sends an indication message to the terminal.

[0524] In the disclosed embodiment, the terminal sends AI model derivation-related data and actual measurement data in two ways: joint sending and separate sending. It is ensured that when sending separately, the base station can correctly match the model derivation-related data and the time measurement data one by one, thereby ensuring the accuracy of AI communication.

[0525] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0526] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, a terminal, a network device, etc.) in any of the above methods.

[0527] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0528] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules.
