[0154] Figure 1 A block diagram of a wireless communication system applicable to the embodiments of the present application is shown. The wireless communication system includes a terminal device (also referred to as a terminal) and a network device.
[0155] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE).

Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.
[0157] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.
[0158] The following first introduces the contents involved in the solution provided in the embodiment of the present application.
[0159] In the New Radio (NR) system, in order to combat the path loss in high-frequency scenarios, the transmitter and receiver obtain matching beam pairs through beam management (BM) to improve the beamforming gain. Specifically, in the current downlink beam management process, the base station selects a suitable Tx beam (transmit beam) for subsequent communication based on the beam measurement information reported by the user equipment (UE), and indicates the selected beam information to the UE. However, in this solution, in order to obtain the optimal beam pair, the base station needs to send a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) and / or a synchronization signal block (Synchronization Signal Block, SSB) on all Tx beams, and the reference signal resource consumption is large. At the same time, the UE needs to use all Rx beams (receive beams) to measure the CSI-RS and / or SSB sent on all Tx beams respectively, and the measurement overhead is large. In order to solve these problems, it is proposed to use artificial intelligence (Artificial Intelligence (AI) or Machine Learning (ML)) technology. Based on the measurement of some beams (pairs) or historical beam (pair) measurement results, the optimal beam (pair) can be predicted, thereby saving reference signal (RS) transmission resources, UE measurement overhead and UE measurement delay.
[0160] However, as data-driven algorithms, AI or ML algorithms have generalization problems and lack theoretical guarantees for performance. In order to ensure the performance of AI or ML applied to communication systems, model monitoring of AI or ML models is required. AI models can be deployed on the base station side or on the UE side. If the model is deployed on the base station side, the base station generally performs model monitoring. In the model monitoring process, the base station configures a reference signal for the UE, and the UE feeds back the measurement results to the base station. The base station calculates the model monitoring index based on the model reasoning results and the information fed back by the UE to determine whether the current model is applicable. The specific feedback content of the UE in the model monitoring process is related to the model monitoring index.
[0161] Specifically, the current air interface AI topic uses the following two sub-use cases as sub-use cases for AI beam management:
[0162] BM-case (beam management case) 1: Spatial beam prediction, that is, predicting the top-K (i.e., the first K) beams (pairs) in beam set SetA based on beam set SetB measured at a certain moment;
[0163] BM-case2: Time domain beam prediction, that is, predicting the Top-K beams (pairs) of the beam set SetA at the next N' moments based on the beam set SetB measured at the historical N moments.
[0164] Among them, the downlink beam in SetB is used for beam measurement, and the measurement result is used as the input of the AI or ML model. The output of the AI or ML model can be the id (identification) of the predicted Top-K beam (pair) of SetA, or the Reference Signal Received Power (RSRP) of the predicted beam (pair) of SetA. Based on the latter (base station or UE), the Top-K beam pair can be selected according to the size of the predicted RSRP (the execution subject of the selection action depends on whether the model is deployed in the base station or UE. The side on which the model is deployed is executed, which can be regarded as post-processing). In addition, in BM-case2, SetB can be equal to SetA, or SetB is not equal to SetA. When SetB is equal to SetA, BM-case2 is a pure time domain beam prediction; when SetB is not equal to SetA, BM-case2 is a spatial domain + time domain beam prediction.
[0165] In addition, the model monitoring indicators currently supported for research include beam prediction related indicators, the difference between the measured RSRP and the predicted RSRP, etc. Among them, the indicator "the difference between the measured RSRP and the predicted RSRP" is applicable when the output of the AI or ML model is the predicted RSRP of the beam (pair) of SetA.
[0166] Among them, the beam prediction related indicators include Top-K / 1 beam prediction accuracy, Top-1 / K beam prediction accuracy and optimal beam prediction accuracy within XdB range. Specifically, the definitions of each indicator are as follows:
[0167] Top-K / 1 beam prediction accuracy: the probability that the predicted Top-K beam includes the actual Top-1 beam;
[0168] Top-1 / K beam prediction accuracy: the probability that the predicted Top-1 beam belongs to the actual Top-K beam;
[0169] The accuracy of optimal beam prediction within X dB range is the probability that the difference between the predicted L1 (layer 1)-RSRP measurement value of the Top-1 beam and the actual L1-RSRP measurement value of the Top-1 beam is within X dB.
[0170] The difference between the measured RSRP and the predicted RSRP refers to the difference between the measured RSRP and the predicted RSRP of certain beams (such as the beam of SetB or the Top-K beam output by the model).
[0171] Specifically, if the "optimal beam prediction accuracy within the XdB range" is used as a model monitoring indicator, it is necessary to calculate the difference between the actual L1-RSRP of the Top-1 beam predicted by the AI or ML model and the actual L1-RSRP of the Top-1 beam (i.e., the beam with the largest actual L1-RSRP measurement value in SetA). The UE can report the measured value of the L1-RSRP of the Top-1 beam predicted by the model and the measured value of the L1-RSRP of the actual Top-1 beam to the base station. Regarding reporting, one implementation method (method 1) is that the UE feeds back the L1-RSRP measurement results of all beams of SetB and SetA to the base station, and the base station performs model inference based on the L1-RSRP of SetB, and selects the measured value of the L1-RSRP of the predicted Top-1 beam (i.e., the actual L1-RSRP) and the measured value of the L1-RSRP of the actual Top-1 beam in SetA from the measurement results of SetA based on the inference results for calculation. This method requires the UE to feed back the L1-RSRP measurement values of all beams in SetA, and the feedback overhead is relatively large. Another implementation method (Method 2) is that the UE only feeds back the L1-RSRP measurement value of the Top-1 beam predicted by the model and the actual L1-RSRP measurement value of the Top-1 beam, or the difference between the two (i.e., the L1-RSRP measurement value of the Top-1 beam predicted by the model and the actual L1-RSRP measurement value of the Top-1 beam). This method requires the UE to first feed back the measurement results of SetB for model reasoning, and then feed back the measurement quantity used to calculate the model monitoring indicator based on the reasoning results of the base station. For the above-mentioned Method 2, taking the BM-Case1 spatial domain beam prediction as an example, the model monitoring process on the base station side can be as follows. Figure 2 As shown; among which:
[0172] If the difference between the predicted L1-RSRP of the Top-K beam output by the model and the measured L1-RSRP is used as an indicator for model monitoring, the UE can report the measured value of the L1-RSRP of the Top-K beam predicted by the model to the base station, and the base station calculates the difference between the two based on the predicted value of the L1-RSRP of the Top-K beam output by the model. Among them, the UE's measurement of the Top-K beam can be completed in step 1: the UE measures the beams of the entire SetA; after the base station completes the model reasoning, it can inform the UE of the reasoning result; the UE selects the L1-RSRP corresponding to the Top-K beam predicted by the model from the measurement results of SetA for feedback.
[0173] In addition, taking BM-Case1 spatial beam prediction as an example, the base station side model monitoring process can also be as follows: Figure 3 As shown; it can be seen that Figure 2The main difference is that if the difference between the predicted L1-RSRP and the measured L1-RSRP of the Top-K beam is used as the indicator for model monitoring, then Figure 3 In this process, the UE does not need to measure the SetA beam (ie, the beam in SetA).
[0174] As mentioned above, if the Figure 2 The model monitoring process is as follows: Step 1 is that the base station sends the reference signals of SetB and SetA. If SetB is a subset of SetA, only the reference signal of SetA needs to be sent; Step 2 is that the UE feeds back the measurement result of the reference signal of SetB, and the base station performs model inference based on the result; Step 3 is that after the base station performs model inference, it informs the UE of the model prediction result (such as the predicted Top-1 beam); Step 4 is that the UE feeds back the L1-RSRP of the actual optimal beam and the predicted L1-RSRP of the Top-1 beam, or feeds back the difference between the two and other information. Among them, the actual optimal beam is obtained by measuring the reference signal of SetA in Step 1.
[0175] In order to implement the above process, steps 1 and 2 can be performed based on the current CSI feedback architecture, but configuration is required: the UE only feeds back the measurement results of SetB when feeding back in step 2. How to implement steps 3 and 4: the base station informs the UE of the inference results of the network-side model, and the UE feeds back based on the inference results needs to be designed. If steps 3 and 4 are completed through the current non-periodic CSI reporting, the UE will measure the non-periodic reference signal after the downlink control information (Downlink Control Information, DCI) is triggered, and then report the measurement results of the non-periodic reference signal. This process will cause unnecessary non-periodic reference signal transmission and / or measurement. Similarly, in Figure 3 In the model monitoring process, steps 3 and 4 are Figure 2 Steps 3 and 4 are similar, except that the amount of feedback may be different, so the same problem exists.
[0176] This can be accomplished by triggering an aperiodic CSI report. Figure 2 and Figure 3Steps 3 and 4 in . Currently, non-periodic CSI feedback is triggered by the CSI request field in the uplink DCI. The CSI request field indicates a trigger state (TriggerState). Radio Resource Control (RRC) signaling establishes an association between each trigger state and one or more non-periodic CSI reports. When the DCI triggers a trigger state, the non-periodic CSI report associated with the trigger state will be triggered. If the non-periodic CSI report is associated with a non-periodic reference signal, and the non-periodic reference signal is sent after the trigger signaling, the measurement resource can be a reference signal set.
[0177] As described above, currently, if the aperiodic CSI report is associated with the aperiodic reference signal, the UE will always measure the aperiodic reference signal after the DCI is triggered, and then report the measurement result of the aperiodic reference signal, which may result in unnecessary aperiodic reference signal transmission and / or measurement.
[0178] Based on the above, the embodiments of the present application provide an information transmission method, device and equipment to solve the problem that the information transmission scheme for non-periodic CSI reporting in the prior art is not flexible enough and causes resource waste. Among them, the method, device and equipment are based on the same application concept. Since the principles of solving the problems by the method, device and equipment are similar, the implementation of the method, device and equipment can refer to each other, and the repeated parts will not be repeated.
[0179] The information transmission method provided in the embodiment of the present application is applied to a terminal, such as Figure 4 As shown, including:
[0180] Step 41: Determine a target reference signal according to the aperiodic channel state information CSI reporting trigger signaling sent by the network device;
[0181] Step 42: Determine a target measurement result corresponding to the target reference signal according to the configuration information sent by the network device;
[0182] Step 43: Send CSI to the network device according to the target measurement result; wherein the target measurement result is: a first measurement result for the target reference signal before receiving the non-periodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the non-periodic CSI reporting trigger signaling.
[0183] The configuration information may directly indicate that the first measurement result is used as the target measurement result, or the second measurement result is used as the target measurement result, or may indicate relevant information capable of determining the following target reference time, but is not limited thereto.
[0184] The information transmission method provided in the embodiment of the present application determines a target reference signal according to a non-periodic channel state information CSI reporting trigger signaling sent by a network device; determines a target measurement result corresponding to the target reference signal according to configuration information sent by the network device; and sends CSI to the network device according to the target measurement result; wherein the target measurement result is: a first measurement result for the target reference signal before receiving the non-periodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the non-periodic CSI reporting trigger signaling; and can support the UE to report the measurement result before or after the non-periodic CSI reporting trigger signaling (for the reference signal related to the signaling) after the non-periodic CSI reporting is triggered, thereby improving the flexibility of reporting, avoiding the UE having to perform non-periodic signal measurement for reporting after the non-periodic CSI reporting is triggered, and thus avoiding the waste of resources caused by unnecessary sending and / or measurement of non-periodic reference signals, and well solving the problem of insufficient flexibility of information transmission schemes for non-periodic CSI reporting in the prior art, resulting in waste of resources.
[0185] Among them, the target reference signal corresponds to the inference result obtained by the network device according to the artificial intelligence AI or machine learning ML model.
[0186] This can support network devices to better monitor models.
[0187] In an embodiment of the present application, determining the target measurement result corresponding to the target reference signal according to the configuration information sent by the network device includes: determining, according to the configuration information sent by the network device, to use the first measurement result as the target measurement result corresponding to the target reference signal under a first condition, and determining to use the second measurement result as the target measurement result corresponding to the target reference signal under a second condition; wherein the first condition includes at least one of the following: the target reference signal is not received within a time period between a moment when the non-periodic CSI reporting trigger signaling is received and a target reference time; the configuration information configures that the CSI reporting is based on a reference signal before the non-periodic CSI reporting trigger signaling; wherein the second condition includes at least one of the following: the target reference signal is received within a time period between a moment when the non-periodic CSI reporting trigger signaling is received and a target reference time; the configuration information configures that the CSI reporting is based on a reference signal after the non-periodic CSI reporting trigger signaling.
[0188] In this way, the first measurement result or the second measurement result can be accurately supported and reported. The target reference signal can be understood as a reference signal associated with or indicated by the non-periodic CSI reporting, but is not limited thereto.
[0189] The target reference time is the time when the CSI is reported or the time when a predefined signal is received.
[0190] In this way, the target reference time can be clarified. Among them, the predefined signal can be: a signal defined by the network device, which is used as a reference; if there is a target reference signal sent after receiving the CSI reporting trigger signaling and before receiving this signal, the UE can report the measurement result of the target reference signal; otherwise, the UE can report the measurement result of the target reference signal before the trigger signaling, but it is not limited to this.
[0191] In an embodiment of the present application, determining the target reference signal based on the non-periodic channel state information CSI reporting trigger signaling sent by the network device includes: determining the target reference signal based on the non-periodic channel state information CSI reporting trigger signaling and first indication information sent by the network device; wherein the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signal associated with the non-periodic CSI reporting trigger signaling.
[0192] This can support the terminal to report the measurement results of some reference signals, further reducing resource consumption.
[0193] The first indication information is carried in the aperiodic CSI reporting triggering signaling, or carried in downlink control information DCI that carries the aperiodic CSI reporting triggering signaling.
[0194] In this way, it is possible to support the implementation of carrying the first indication information in multiple ways.
[0195] In an embodiment of the present application, the CSI sent to the network device includes at least one of the following: the layer 1 reference signal received power L1-RSRP of the target reference signal; the information of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; and second indication information, wherein the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located is within a preset range.
[0196] In this way, the network device can be supported to perform model monitoring in multiple ways. The target reference signal information may include information such as L1-RSRP and / or index of the target reference signal, which is not limited here.
[0197] The present application also provides an information transmission method, which is applied to a network device, such as Figure 5 As shown, including:
[0198] Step 51: Send aperiodic channel state information CSI reporting trigger signaling and configuration information to the terminal;
[0199] Step 52: Receive the CSI sent by the terminal according to the non-periodic CSI reporting trigger signaling and configuration information; wherein the non-periodic CSI reporting trigger signaling is used by the terminal to determine the target reference signal, and the configuration information is used by the terminal to determine the target measurement result corresponding to the target reference signal; the target measurement result is: a first measurement result for the target reference signal before receiving the non-periodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the non-periodic CSI reporting trigger signaling.
[0200] The configuration information may directly indicate that the first measurement result is used as the target measurement result, or the second measurement result is used as the target measurement result, or may indicate relevant information capable of determining the following target reference time, but is not limited thereto.
[0201] The information transmission method provided in the embodiment of the present application sends a non-periodic channel state information CSI reporting trigger signaling and configuration information to the terminal; receives the CSI sent by the terminal according to the non-periodic CSI reporting trigger signaling and the configuration information; wherein the non-periodic CSI reporting trigger signaling is used by the terminal to determine the target reference signal, and the configuration information is used by the terminal to determine the target measurement result corresponding to the target reference signal; the target measurement result is: a first measurement result for the target reference signal before receiving the non-periodic CSI reporting trigger signaling, or a second measurement result for the target reference signal after receiving the non-periodic CSI reporting trigger signaling; it can support the UE to report the measurement result before or after the non-periodic CSI reporting trigger signaling (for the reference signal related to the signaling) after the non-periodic CSI reporting is triggered, thereby improving the flexibility of reporting, avoiding the UE having to perform signal measurement for reporting after the non-periodic CSI reporting is triggered, and thus avoiding the waste of resources caused by unnecessary sending and / or measurement of non-periodic reference signals, and well solving the problem of insufficient flexibility of the information transmission scheme for non-periodic CSI reporting in the prior art, resulting in waste of resources. The sending to the terminal here only indicates that the network device sends the relevant information in the form of wireless signals, and the target recipient is the terminal. The terminal obtains the relevant information by receiving the wireless signals.
[0202] Among them, the target reference signal corresponds to the inference result obtained by the network device according to the artificial intelligence AI or machine learning ML model.
[0203] This can support network devices to better monitor models.
[0204] Furthermore, the information transmission method also includes: obtaining a monitoring data set based on the inference result and the target measurement result corresponding to the inference result; obtaining model monitoring indicator data based on the monitoring data set; and determining whether the AI or ML model on the network device side meets the usage conditions based on the model monitoring indicator data.
[0205] This can support the complete monitoring of the model. Among them, "whether the use conditions are met" can also be called: whether it is applicable, whether it can still work, etc., which is not limited here.
[0206] Among them, sending non-periodic CSI reporting trigger signaling to the terminal includes: sending non-periodic CSI reporting trigger signaling and first indication information to the terminal; wherein the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signal associated with the non-periodic CSI reporting trigger signaling.
[0207] This can support the terminal to report the measurement results of some reference signals, further reducing resource consumption.
[0208] In the embodiment of the present application, the first indication information is carried in the aperiodic CSI reporting trigger signaling, or carried in the downlink control information DCI that carries the aperiodic CSI reporting trigger signaling.
[0209] In this way, it is possible to support the implementation of carrying the first indication information in multiple ways.
[0210] Among them, the CSI sent by the terminal includes at least one of the following items: the layer 1 reference signal received power L1-RSRP of the target reference signal; the information of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located; second indication information, the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signals in the set where the target reference signal is located is within a preset range.
[0211] In this way, the network device can be supported to perform model monitoring in multiple ways. The target reference signal information may include information such as L1-RSRP and / or index of the target reference signal, which is not limited here.
[0212] The information transmission method provided in the embodiment of the present application is illustrated below by taking a base station as an example of the network device.
[0213] In view of the above technical problems, the embodiment of the present application provides an information transmission method, which can be specifically implemented as a CSI reporting method, which is used for triggering the UE to report information to the base station according to the inference result after the base station completes the AI model inference, thereby realizing model monitoring on the base station side. This solution mainly includes the following contents:
[0214] Part 1. The base station configures the measurement resources associated with the CSI report, and after completing the model inference (according to the inference result), the base station triggers the non-periodic CSI report (corresponding to the above-mentioned sending of the non-periodic channel state information CSI report trigger signaling and configuration information to the terminal):
[0215] a) if no reference signal (corresponding to the target reference signal) associated with the aperiodic CSI reporting is sent between the aperiodic CSI reporting trigger signaling and the aperiodic CSI reporting time (corresponding to the moment of the above-mentioned CSI reporting) (or before a certain defined reference time (such as the moment of receiving the above-mentioned predefined signal)) (corresponding to the above-mentioned failure to receive the target reference signal in the time period between the moment of receiving the aperiodic CSI reporting trigger signaling and the target reference time), or the base station configures the CSI reporting to be based on the reference signal before the trigger signaling (corresponding to the above-mentioned configuration information configuring the CSI reporting to be based on the reference signal before the aperiodic CSI reporting trigger signaling), the UE feeds back the measurement result of the reference signal associated with the (aperiodic) CSI reporting before the trigger signaling (corresponding to the above-mentioned determination, according to the configuration information sent by the network device, to use the first measurement result as the target measurement result corresponding to the target reference signal under the first condition; and sending CSI to the network device according to the target measurement result), and the measurement result is stored in advance by the UE (i.e., pre-stored);
[0216] b) if a reference signal associated with the non-periodic CSI reporting is sent after the non-periodic CSI reporting trigger signaling and before the non-periodic CSI reporting time (or before a defined reference time) (corresponding to the target reference signal being received in the time period between the moment of receiving the non-periodic CSI reporting trigger signaling and the target reference time), or the base station configures the CSI reporting to be based on the reference signal after the trigger signaling (corresponding to the above configuration information configuring the CSI reporting to be based on the reference signal after the non-periodic CSI reporting trigger signaling), the UE feeds back the measurement result of the reference signal associated with the (non-periodic) CSI reporting after the trigger signaling (corresponding to the above configuration information sent by the network device, determining under the second condition to use the second measurement result as the target measurement result corresponding to the target reference signal; and sending CSI to the network device according to the target measurement result);
[0217] This section mainly involves: the UE needs to determine whether to report CSI based on the measurement result of the reference signal before the CSI reporting trigger signaling (corresponding to the first measurement result mentioned above) or the measurement result of the reference signal after the trigger signaling (corresponding to the second measurement result mentioned above). In other words, it indicates that: the UE stores the measurement result and determines whether the measurement result to be fed back is the measurement result of the reference signal before the trigger signaling or the measurement result of the reference signal after the trigger signaling.
[0218] In addition, considering that model monitoring is essentially a comparison of the performance of the AI algorithm and the performance of a benchmark result at the same point in time, the sending of the reference signal and the reporting of the UE need to ensure the so-called "same point in time", that is, to clarify which reference signal or signals the UE measures. Specifically, the measurement time of the UE can be specified through the definition of CSI reference resource, but it is not limited to this.
[0219] Part 2. Optionally, the base station may instruct the UE to measure or report only part of the reference signals associated with the triggered CSI report (corresponding to the Top-K beams output by the model) (that is, the measurement object can be "indicated"), corresponding to the above-mentioned sending of non-periodic CSI report trigger signaling and first indication information to the terminal; wherein the first indication information is used to instruct the terminal to measure or report the measurement results of part of the reference signals associated with the non-periodic CSI report trigger signaling. Specifically, the indication information may be configured in the trigger state of the non-periodic CSI (corresponding to the above-mentioned first indication information being carried in the non-periodic CSI report trigger signaling) or carried by the DCI that triggers the non-periodic CSI report (corresponding to the above-mentioned first indication information being carried in the downlink control information DCI that carries the non-periodic CSI report trigger signaling); specifically, the indication information may be implemented in at least one of the following ways:
[0220] In implementation a), the indication information may be expressed in the form of a bitmap, and the length of the bitmap is equal to the number of reference signals in the reference signal set associated with the (non-periodic) CSI reporting. For example, a bit "1" represents that the UE measures the corresponding reference signal, and a bit "0" represents that the UE does not measure the corresponding reference signal.
[0221] In implementation b), the indication information may be represented as N bits, and the decimal value corresponding to the N bits represents the 2 associated with the (non-periodic) CSI reporting measured by the UE. N If CSI reporting is associated with 8 reference signals, a 3-bit indication may be used, where 000 represents the first reference signal, 001 represents the second reference signal, and so on.
[0222] In implementation method c), the indication information may be represented as (at least one) integer value in the range of 1..M, where M is the number of reference signals associated with the (non-periodic) CSI report. The integer value i represents that the UE needs to measure the i-th reference signal. Specifically, the indication information may be a plurality of integer values used to indicate the UE to measure a plurality of reference signals. The method of implementation method b) can only indicate one reference signal through N bits. Generally, the indication method of implementation method b) can be used in L1 signaling (such as DCI) indication, and implementation method c) can generally be used in RRC signaling indication.
[0223] This section mainly involves: the UE only measures or reports the measurement results of some reference signals associated with non-periodic CSI reporting; it can be understood as indicating that: the UE determines, based on part 1, whether the feedback measurement result is a reference signal before or after the trigger signaling, and on this basis, only feeds back a subset of the reference signals associated with the trigger signaling.
[0224] Part 3. The UE feeds back the measurement result (corresponding to sending the CSI to the network device according to the target measurement result) according to the trigger information (which may include the above-mentioned CSI reporting trigger signaling and configuration information). The specific feedback content may be configured by the base station, and the feedback content may be one of the following:
[0225] a) the L1-RSRP of the reference signal associated with or indicated by the triggered CSI reporting (corresponding to the layer 1 reference signal received power L1-RSRP of the above-mentioned target reference signal);
[0226] b) the reference signal associated with or indicated by the triggered CSI report and the maximum L1-RSRP of the reference signal in the set to which the reference signal belongs (corresponding to the L1-RSRP of the Top-1 beam predicted by the model and the actual Top-1 beam in SetA), corresponding to the information of the above-mentioned target reference signal and the maximum L1-RSRP of the reference signal in the set to which the target reference signal belongs;
[0227] c) the difference between the L1-RSRP of the reference signal associated with or indicated by the triggered CSI report and the maximum L1-RSRP of the reference signals in the set to which the reference signal belongs (corresponding to the difference between the L1-RSRP of the Top-1 beam predicted by the model and the actual Top-1 beam in SetA), corresponding to the difference between the L1-RSRP of the above-mentioned target reference signal and the maximum L1-RSRP of the reference signals in the set to which the target reference signal belongs;
[0228] d) Indicates whether the difference between the L1-RSRP of the reference signal associated with or indicated by the triggered CSI report and the maximum L1-RSRP of the reference signal in the set to which the reference signal belongs is within the XdB range (corresponding to the above-mentioned second indication information, the second indication information is used to indicate whether the difference between the L1-RSRP of the target reference signal and the maximum L1-RSRP of the reference signal in the set to which the target reference signal belongs is within a preset range), where X may be specified by the protocol or configured by the base station; the feedback information may be "1" or "0", such as "1" represents within the XdB range, and "0" represents not within the XdB range.
[0229] As described above, part 3 indicates which measurement results of the measurement objects are fed back by the UE.
[0230] The following is a specific example to illustrate this solution.
[0231] Embodiment 1:
[0232] In this embodiment, it is assumed that the base station deploys an AI or ML model for spatial prediction, that is, the optimal beam in SetA is predicted based on the measurement results of SetB beam (i.e., the beam in SetB). The input of the AI or ML model is the L1-RSRP of SetB beam, and the output is the ID of the predicted optimal beam in SetA. Figure 6 As shown, SetA includes 32 transmitting beams, SetB includes 8 transmitting beams (beam #1, beam #5, beam #9, beam #13, beam #17, beam #21, beam #25, beam #29), and SetB is a subset of SetA.
[0233] Specifically, it is assumed that the model monitoring indicator is the optimal beam prediction accuracy within the range of 1dB. The base station configures CSI reporting #1 and CSI reporting #2 (including configuring the reporting type (periodic or non-periodic), and may also include a trigger status (which may indicate the reference signal to be measured and reported)). Among them, CSI reporting #1 is a periodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. The base station may instruct the UE to report the measurement results of part of the reference signals of SetA in CSI reporting #1. Part of the reference signals of SetA correspond to the 8 reference signals of SetB. CSI reporting #2 is a non-periodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. Configure aperiodic CSI reporting trigger state #1 to trigger state #24. Aperiodic CSI reporting trigger state #1 to trigger state #24 are all associated with aperiodic CSI reporting #2. However, different integer values are indicated in the indication information of different trigger states. The integer value i represents the measurement result of the UE measuring or reporting the i-th reference signal among the 32 reference signals corresponding to the SetA beam. The reporting content of CSI reporting #2 is the L1-RSRP of the i-th reference signal and the maximum L1-RSRP of the reference signals in the set to which the reference signal belongs.
[0234] Specific as Figure 7As shown, according to the base station configuration information, the UE measures the reference signal of SetA at T0, reports the L1-RSRP of SetB at T1 (performs CSI reporting #1), and stores the measurement results of the reference signal in SetA. After receiving the L1-RSRP reported by the UE, the base station performs model inference, and the model inference result is: beam #3 in SetA is the optimal beam. The base station triggers the non-periodic CSI trigger state #5 (i.e., triggers the non-periodic CSI reporting) through DCI signaling at time T2, corresponding to the non-periodic CSI reporting #2, and the reporting time is T3. Corresponding to the model inference result, the indication information of trigger state #5 (corresponding to the above-mentioned first indication information) is an integer value 3 (i.e., indicating the measurement result of the reference signal of beam #3); corresponding to the above-mentioned target reference signal and the inference result obtained by the network device according to the artificial intelligence AI or machine learning ML model. Between T2 and T3, it is assumed that no reference signal in SetA is sent, so the UE performs CSI reporting #2 at time T3 based on the measurement of SetA at time T0. The UE's report content is the L1-RSRP of the third reference signal in SetA at time T0 (i.e., the reference signal corresponding to beam #3) and the maximum L1-RSRP in SetA at time T0 (corresponding to the above-mentioned failure to receive the target reference signal in the time period between the time when the non-periodic CSI report trigger signaling is received and the target reference time; the first measurement result is used as the target measurement result corresponding to the target reference signal). After receiving the UE's CSI report #2, the base station can calculate whether the difference between the L1-RSRP of the optimal beam predicted by the model and the actual optimal beam is within 1dB (corresponding to the above-mentioned acquisition of model monitoring indicator data; based on the model monitoring indicator data, determine whether the AI or ML model on the network device side meets the usage conditions).
[0235] Embodiment 2:
[0236] In this embodiment, it is assumed that the base station side deploys an AI or ML model for airspace prediction. The input of the AI or ML model is the L1-RSRP of the SetB beam, and the output is the predicted L1-RSRP of all beams in SetA. The beam configuration on the base station side can be as follows: Figure 6As shown. It is specifically assumed that the model monitoring indicator is the difference between the predicted L1-RSRP and the measured L1-RSRP of the Top-3 beams output by the model. The base station configures CSI reporting #1 and CSI reporting #2. Among them, CSI reporting #1 is a periodic CSI reporting, and the associated measurement resources are the 8 reference signals corresponding to the SetB beam. CSI reporting #2 is a non-periodic CSI reporting, and the associated measurement resources are the 32 reference signals corresponding to the SetA beam. Configure non-periodic CSI reporting trigger state #1 to trigger state #10, and non-periodic CSI reporting trigger state #1 to trigger state #10 are all associated with non-periodic CSI reporting #2, but the bitmap information in the indication information of different trigger states (corresponding to the above-mentioned first indication information) is different, and the bitmap length can be 32 bits. The reporting content corresponding to CSI reporting #2 is the L1-RSRP of the reference signal corresponding to the bitmap information "1".
[0237] Specific as Figure 8 As shown, according to the base station configuration information, the UE measures the reference signal of SetB at T0 and reports the L1-RSRP of SetB at T1 (performs CSI reporting #1). After receiving the L1-RSRP reported by the UE, the base station performs model inference, and the model inference result is: beam #3, beam #12, and beam #20 in SetA are Top-3 beams. The base station triggers the non-periodic CSI trigger state #2 (i.e., triggers non-periodic CSI reporting) through DCI signaling at time T2, corresponding to non-periodic CSI reporting #2, and the CSI reporting time is T4. Corresponding to the model inference result, the bitmap indication information of trigger state #2 is [00100000000100000001000000000000], indicating that the UE measures and reports the L1-RSRP of the 3rd, 12th, and 20th reference signals in the SetA reference signal associated with the non-periodic CSI report #2; corresponding to the above-mentioned target reference signal and the inference result obtained by the network device according to the artificial intelligence AI or machine learning ML model. At time T3, the base station sends the 3rd, 12th, and 20th reference signals, and the UE performs CSI reporting #2 at time T4 based on the measurement result at time T3. The reporting content of the UE corresponds to the L1-RSRP of the 3rd, 12th, and 20th beams in SetA (corresponding to the above-mentioned target reference signal received in the time period between the time when the non-periodic CSI report trigger signaling is received and the target reference time; the second measurement result is used as the target measurement result corresponding to the target reference signal). After receiving CSI report #2 from the UE, the base station can calculate the difference between the predicted L1-RSRP value of the Top-3 beams predicted by the AI model and the measured value of the L1-RSRP of the predicted Top-3 beams.
[0238] From the above, the solution of this embodiment 2 can implement model monitoring based on the difference between the predicted L1-RSRP value and the L1-RSRP measurement value of the Top-K (K=3) beam, avoid sending the SetA reference signal, and reduce RS overhead.
[0239] In addition, in the present scheme, for this embodiment 2, it can also be implemented as follows: the base station sends the reference signal of Set A at time T0, and indicates the bitmap of trigger state #2 at time T2, and no longer performs the above-mentioned operation at time T3; the UE feeds back the corresponding measurement result in Set A at time T0 at T4 according to the bitmap indicated at time T2, but is not limited to this.
[0240] It should be noted here that the relevant contents of each example can be referenced to each other, and the repeated contents will not be repeated.
[0241] From the above, the base station side in the solution provided by the embodiment of the present application involves the following contents: the base station triggers non-periodic CSI reporting according to the inference results of the AI or ML model, which is used to calculate the model monitoring index (using the results reported by the UE). Specifically: the base station can record the inference results of each AI or ML model and the measurement results corresponding to the model inference fed back by the UE (corresponding to the above-mentioned monitoring data set obtained according to the inference results and the target measurement results corresponding to the inference results); the base station calculates the average model monitoring index based on the statistics of multiple results (corresponding to the above-mentioned acquisition of model monitoring index data according to the monitoring data set), so as to determine whether the AI or ML model on the base station side can still work (corresponding to the above-mentioned determination of whether the AI or ML model on the network device side meets the use conditions according to the model monitoring index data). Among them, the measurement of the reference signal associated with the non-periodic CSI reporting can be before or after the trigger signaling, and can be the measurement of part of the associated reference signal. Correspondingly, the UE side in the solution provided by the embodiment of the present application involves the following contents:
[0242] 1) The UE reports CSI according to the configuration information of the base station, and determines whether the reported information is based on the measurement result of the reference signal before the CSI report trigger signaling or the measurement result of the reference signal after the trigger signaling, and the measurement result is stored in advance by the UE; that is, the UE needs to store the measurement result before the trigger signaling, and determine whether the feedback measurement result is before the trigger signaling or after the trigger signaling according to the trigger signaling.
[0243] 2) According to the indication information of the base station, the UE may only measure or report the measurement results of some reference signals associated with the CSI report;
[0244] 3) The feedback content of the UE can be configured by the base station. For the specific feedback content, please refer to the above part 3 and will not be repeated here.
[0245] Based on the above, in this solution, it can be: DCI trigger result feedback, the feedback reference signal measurement is not necessarily sent after the trigger signaling (that is, DCI is only a trigger result feedback, the UE does not necessarily continue to measure the reference signal after receiving the DCI, and the UE feedback can be Figure 2 or Figure 3 Correspondingly, the non-periodic reference signal can be sent before or after the trigger.
[0246] In summary, this solution solves the problem of how the UE reports information for model monitoring to avoid resource waste when the base station side performs model training and model reasoning. Specifically, the embodiment of the present application adopts a solution of non-periodic reporting after the base station completes model reasoning: the base station triggers the UE to report information for model monitoring based on the reasoning result, and the result reported by the UE can be based on the measurement before the trigger signaling or the measurement after the trigger signaling. In addition, the base station can instruct the UE to measure or report part of the measurement resources associated with the CSI report based on the reasoning result, so that the UE reports the L1-RSRP measurement value of the beam predicted by the model, thereby assisting the base station in calculating the model monitoring indicator and saving resources. The embodiment of the present application can implement a solution for AI model performance monitoring on the base station side and improve the performance of AI models applied to communication networks.
