[0030] Functional framework of AI / ML model

[0031] The 3rd generation partnership project (3GPP) studied in Release 18 (Rel18) whether artificial intelligence (AI) / machine learning (ML) model is helpful to improve the performance of the physical layer, and the relevant research results are recorded in Technical Report TR38.843. In addition to recording the evaluation methods and results related to AI / ML model, this technical report also records the steps and content of how to manage AI / ML model, which forms the content of life cycle management (LCM) in this technical report. It should be noted that LCM is a relatively broad term, and its content includes data collection, model training, model identification, model transmission, model inference, model selection, model activation, model deactivation, model replacement and fallback, model monitoring, model updating, terminal device capability reporting, etc.

[0032] For ease of understanding, the LCM of the AI / ML model is introduced below in conjunction with FIG. 2.

[0033] As an example, FIG. 2 illustrates a functional framework of an AI / ML model. After the model training is completed and the model is deployed in a communication device, the model can be utilized for model inference, which refers to a process of obtaining a corresponding output result after a specific input is given, for example. The AI / ML model used for model inference can be subjected to model monitoring at irregular intervals, and the model can be managed based on the result of the model monitoring. The content of the model management includes, for example, deactivating the model or switching to a model with better performance in the case of poor or unsuitable model performance.

[0034] Referring to FIG. 2, an AI / ML model can generally include functional modules such as data collection, model training, model storage, model inference, and model management. Hereinafter, these functional modules are briefly described.

[0035] Among them, the data collection module is used to collect data, such as training data, monitoring data, and inference data. The model training module can train the model using the training data. The model storage module is used to store the trained model so as to be used later according to actual needs. The model inference module is used to perform model inference, for example, to obtain the output result of the model after providing the model with specific inference data, which is usually a prediction result, also known as inference result or inference result. The model management module is used to monitor and / or manage the model. For example, the model management module can monitor the model using monitoring data (or model label), and feed back information to the model training module in the case of poor model performance, so as to retrain the model. For another example, the model management module can send indication information to the model storage module to complete the deployment of a specific model. For another example, the model management module can send indication information to the model inference module in the case of poor model performance or unsuitable model, to instruct to deactivate the model.

[0036] After the AI / ML model is trained using the training data, the trained model is stored so as to be deployed later according to actual needs. After the model is deployed, the communication device with the deployed model can use the model for inference, for example, to provide the model with the measurement value of RRM measurement and output the prediction value for the measurement result by the model, and the model can be monitored in this process, so as to manage the model according to the monitoring result.

[0037] RRM measurement

[0038] In a cellular communication system of 3GPP, a terminal device generally needs to determine the strength or quality of a wireless signal of a current serving cell and a neighboring cell by measurement. For example, the terminal device can measure the signal strength of a cell, i.e., the reference signal receiving power (RSRP). For another example, the terminal device can measure the signal quality of a cell, i.e., the reference signal receiving quality (RSRQ). For yet another example, the terminal device can measure the signal to interference noise ratio (SINR) of a cell. Such measurement can be referred to as RRM measurement. After the terminal device performs the RRM measurement, the terminal device can report the related content of the RRM measurement to a network device in a measurement report, so that the network device can make a relevant decision according to the content of the measurement report, such as performing a cell handover decision, a beam handover decision, etc.

[0039] The measurement report can be carried in a radio resource control (RRC) message, for example. The measurement report can include a specific measurement event and / or a measurement result. In the measurement report, the cell reported by the terminal device can include the current serving cell and / or the neighboring cell. For example, the terminal device can report the signal measurement value of the current serving cell. Or, the terminal device can report the signal measurement value of the current serving cell and the neighboring cell. The measurement object included in the measurement report can be various, such as an intra-frequency, inter-frequency or inter-system frequency, etc.

[0040] Measurement configuration

[0041] The network device can issue measurement configuration (MeasConfig) information for the terminal device, where the MeasConfig information includes, for example, measurement targets, report configuration (ReportConfig), measurement identification, s-Measure configuration, gap configuration, and the like. The report configuration includes, for example, report types (periodic triggering or event triggering), condition triggering configuration, cell global identifier (ID), and the like. Detailed contents related to MeasConfig and ReportConfig can be found in 3GPP protocol TS38.331, which will not be described here. The above configuration can be sent from the network device to the terminal device through RRC signaling from the air interface, and the terminal device can perform cell signal measurement based on the configuration, for example, including measurement of RSRP, RSRQ, and SINR, and timely report the measurement values obtained by measurement to the network device according to the report configuration, so that the network device makes relevant decisions, such as performing cell switching decisions, beam switching decisions, and the like.

[0042] Prediction of measurement events

[0043] Prediction of measurement events is one of several use cases of the current artificial intelligence (AI) mobility (AI mobility) project. The method of measurement prediction generally includes direct prediction and indirect prediction. Among them, direct prediction is to directly predict whether a measurement event such as A3 event will occur in the future based on historical measurement data; indirect prediction is to first predict the measurement value of the measurement result in the future based on historical measurement data, and then judge whether a measurement event will occur based on the predicted measurement value using the traditional switching mechanism. As an example, based on the RSRP value in the past 2s, the RSRP value in the future 3s is predicted, and the predicted RSRP value is used to judge whether A3 event will occur in the future 3s using the traditional measurement event judgment method.

[0044] Prediction of measurement events generally requires signal measurement values such as RSRP or RSRQ of the current serving cell and at least one neighbor cell. In theory, measurement event prediction can also be based solely on the signal measurement value of the serving cell, but the prediction accuracy will be relatively poor. Therefore, the prediction of measurement events in the embodiments of the present application can use the signal measurement value of the neighbor cell, and can use it as one of the conditions for triggering measurement event prediction.

[0045] In the prediction scenario of measurement events, the AI / ML model can be deployed at the terminal device side, or at the network device side, or at both the terminal device side and the network device side. When the AI / ML model is deployed at the terminal device, for direct prediction, the terminal device directly predicts whether a measurement event will occur in a future period of time based on historical measurement results and reports it to the network device. For indirect measurement, the terminal device needs to predict the measurement results in a future period of time based on historical measurement results, and determine whether a measurement event will occur based on the predicted values. For example, the terminal device can report the predicted values to the network device through the air interface, and the network device determines whether a measurement event will occur in a future period of time based on the predicted values reported by the terminal device; or the terminal device infers whether a measurement event will occur based on the predicted values and in combination with the relevant configuration parameters configured by the network device for a certain measurement event.

[0046] Whether it is direct measurement or indirect measurement, the AI / ML model needs to take the historical measurement results in a measurement period, for example, the actual measurement values in the above-mentioned 2s, as the input of the AI / ML model. If the measurement period is short, the amount of data input into the AI / ML model may not be enough for the AI / ML model to make accurate predictions of measurement events. The shortest measurement period required for the application of the AI / ML model can be referred to as the minimum input duration corresponding to the AI / ML model.

[0047] S measurement

[0048] In the NR system, in order to save the energy consumption of the terminal device, the terminal device usually only measures the signal quality of the current serving cell and does not measure the signal quality of the neighbor cell. In the case of a specific event, for example, A2 event, that is, the signal quality of the serving cell is lower than a predetermined threshold, the network device will only issue measurement configuration information for neighbor cell measurement to the terminal device. The terminal device measures the signal quality of the neighbor cell based on the measurement configuration information.

[0049] If the measurement configuration information does not include the configuration of S measurement or S measurement is deactivated, the terminal device starts measuring the neighbor cell after receiving the measurement configuration information; if the measurement configuration information includes the configuration of S measurement, the terminal device will only start measuring the neighbor cell if the corresponding measurement condition of S measurement is met. The corresponding measurement condition of S measurement, for example, means that the signal measurement value of the current serving cell is less than a predetermined threshold. In the case where the signal measurement value of the current serving cell is less than the predetermined threshold, the terminal device will start measuring the non-serving cell. From the occurrence of A2 event to the satisfaction of the corresponding measurement condition of S measurement, a period of time needs to be experienced, so the main purpose of introducing S measurement is to reduce the energy consumption of the terminal device for RRM measurement during this period of time.

[0050] The inference (or prediction) process of the terminal device maintaining the AI / ML model is very energy-consuming, and the measurement event usually does not occur frequently, for example, once every 5s on average. If the prediction of the measurement event is performed according to the period of the RRM measurement, for example, 20ms, a large amount of energy of the terminal device will be wasted, and the valuable computing resources of the terminal device will be occupied, affecting the development of other services.

[0051] In the current discussion of the 3GPP AI mobility project, if it is considered that the inference of the measurement event can be continuously performed, a large amount of meaningless data about the measurement event (for example, the signal of the serving cell of the terminal device is good at this time) will be collected in the training process of the AI / ML model, thereby causing the deviation between the simulation results and the actual commercial results.

[0052] Therefore, in the embodiments of the present application, the terminal device performs the prediction of the measurement event under certain conditions, which avoids the energy consumption and the waste of computing resources caused by the frequent prediction of the measurement event by the terminal device, and reduces the burden of the terminal device.

[0053] The embodiments of the present application will be described in detail below with reference to FIG. 3.

[0054] FIG. 3 is a flowchart of a wireless communication method provided by the embodiments of the present application. As shown in FIG. 3, the method includes step 310.

[0055] In step 310, the terminal device performs the prediction of the measurement event under the condition that a first condition is met.

[0056] That is, the first condition is used to trigger the terminal device to perform the prediction of the measurement event.

[0057] In this way, the terminal device does not frequently perform the prediction of the measurement event, so that the prediction of the measurement event can be performed at the necessary time, and the waste of energy consumption and computing resources caused by the frequent prediction of the measurement event by the terminal device is avoided while the prediction of the measurement event is timely performed.

[0058] In an implementation manner, the first condition is associated with one or more of the following: S measurement; a signal measurement value of a serving cell of the terminal device; a signal measurement value of a neighbor cell of the terminal device; a moving speed of the terminal device; and a region in which the terminal device is located.

[0059] In an implementation, the first condition comprises one or more of the following: the measurement condition corresponding to the S-measure is satisfied; a signal measurement value of a serving cell of the terminal device is less than or equal to a first threshold; a signal measurement value of a neighbor cell of the terminal device is greater than or equal to a second threshold; the signal measurement value of the serving cell of the terminal device is less than or equal to a third threshold, and the signal measurement value of the neighbor cell of the terminal device is greater than or equal to a fourth threshold; a moving speed of the terminal device is greater than or equal to a fifth threshold; the terminal device is located in a predetermined area.

[0060] The first condition comprises that the signal measurement value of the serving cell of the terminal device is less than or equal to a first threshold, which is more suitable for the scenario of intra-frequency and homogeneous network. The smaller signal measurement value of the serving cell indicates that the terminal device has moved to the boundary of the cell.

[0061] The first condition comprises that the signal measurement value of the neighbor cell of the terminal device is greater than or equal to a second threshold, which is more suitable for the scenario of intra-frequency and heterogeneous network and the scenario of inter-frequency and heterogeneous network. The larger signal measurement value of the neighbor cell indicates that the terminal device has moved to the range of the cell.

[0062] The first condition comprises that the signal measurement value of the serving cell of the terminal device is less than or equal to a third threshold, and the signal measurement value of the neighbor cell of the terminal device is greater than or equal to a fourth threshold, which is more suitable for the scenario of intra-frequency and homogeneous network and the scenario of inter-frequency and co-site.

[0063] The above conditions can be used alone by the terminal device to determine whether to predict the measurement event. For example, the measurement event is predicted when the signal measurement value of the serving cell of the terminal device is less than or equal to the first threshold; for another example, the measurement event is predicted when the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the second threshold; for another example, the measurement event is predicted when the signal measurement value of the serving cell of the terminal device is less than or equal to the third threshold, and the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the fourth threshold.

[0064] Alternatively, the above conditions can be combined to determine whether the terminal device predicts the measurement event. Optionally, the moving speed of the terminal device is greater than or equal to the fifth threshold, and / or the terminal device is located in the predetermined area, which can be used as an auxiliary condition of other conditions to determine when the terminal device starts to predict the measurement event.

[0065] For example, the terminal device triggers the prediction of the measurement event only when the terminal device meets the measurement condition corresponding to the S measurement and the terminal device meets the condition that the moving speed of the terminal device is greater than or equal to the fifth threshold; for another example, the terminal device triggers the prediction of the measurement event only when the terminal device meets the measurement condition corresponding to the S measurement and the terminal device is located in the predetermined area; for another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the serving cell of the terminal device is less than or equal to the first threshold and the moving speed of the terminal device is greater than or equal to the fifth threshold; for another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the serving cell of the terminal device is less than or equal to the first threshold and the terminal device is located in the predetermined area.

[0066] For another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the second threshold and the moving speed of the terminal device is greater than or equal to the fifth threshold; for another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the second threshold and the terminal device is located in the predetermined area; for another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the serving cell of the terminal device is less than or equal to the third threshold, the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the fourth threshold, and the moving speed of the terminal device is greater than or equal to the fifth threshold; for another example, the terminal device triggers the prediction of the measurement event only when the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the second threshold, the signal measurement value of the serving cell of the terminal device is less than or equal to the third threshold, the signal measurement value of the neighbor cell of the terminal device is greater than or equal to the fourth threshold, and the terminal device is located in the predetermined area. In these examples, the number of predictions of the measurement event is further reduced, and therefore, the two conditions that the moving speed of the terminal device is greater than or equal to the fifth threshold and the terminal device is located in the predetermined area can be referred to as relaxed conditions of other conditions.

[0067] When the moving speed of the terminal device is relatively large, for example, greater than 60 km / h, the channel state of the terminal device changes relatively fast, and therefore, the prediction of the measurement event triggered under the condition that the moving speed of the terminal device is greater than or equal to the fifth threshold can obtain better access performance of the terminal device at a low speed in advance. In addition, in other implementation manners, the first condition can also include other conditions related to the moving speed of the terminal device, for example, the number of speed switching of the terminal device in a unit time is greater than a corresponding threshold.

[0068] The predetermined area is, for example, a multi-cell hotspot coverage area, a multi-cell coverage area, or the like, and the wireless environment in the area is more complex, and therefore, the prediction of the measurement event when the terminal device enters the predetermined area can obtain the target cell and the corresponding access time in advance, thereby better improving the throughput.

[0069] In some implementations, the prediction of the measurement event is initiated after the first condition is met and a first time duration elapses. That is, the terminal device does not immediately perform the prediction of the measurement event when the first condition is met, but waits until the first time duration elapses before performing the prediction of the measurement event. The first time duration can be used for the terminal device to perform RRM measurements, such as measuring RSRP and / or RSRQ of the serving cell and the neighbor cells.

[0070] In some implementations, the first time duration is determined based on a timer configured by the network device.

[0071] The timer can be configured by the network device. The timer can be configured by the network device via RRC signaling. The timer can be configured by the network device via RRC signaling, such as RRCReconfiguration or RRCResume, or a newly defined RRC signaling. The configuration information of the timer can be carried in the measurement configuration information of the RRM measurement, or transmitted independently from the measurement configuration information.

[0072] The timer can be configured by the network device. The timer can be configured by the network device via RRC signaling. The timer can be configured by the network device via RRC signaling, such as RRCReconfiguration or RRCResume, or a newly defined RRC signaling. The configuration information of the timer can be carried in the measurement configuration information of the RRM measurement, or transmitted independently from the measurement configuration information.

[0073] In some implementations, the prediction of the measurement event is based on a prediction model, and input data of the prediction model is signal measurement values within a second time duration, and the first time duration is greater than or equal to a minimum value of the second time duration. The prediction model can be an AI / ML model. The minimum value of the second time duration can be a minimum input time duration of the AI / ML model.

[0074] Here, the first time duration is set to be greater than or equal to the minimum value of the second time duration, because the terminal device starts to perform measurements of the neighbor cells only when the first condition is met, and since the prediction of the measurement event requires signal measurement values, such as RSRP and / or RSRQ, of the serving cell and the neighbor cells within a period of time, the terminal device can trigger the prediction of the measurement event only after the first condition is met and the first time duration elapses, which is sufficient for obtaining the signal measurement results for the prediction of the measurement event. That is, the start time of the prediction of the measurement event is determined based on the time when the first condition is met and the first time duration.

[0075] Of course, the timer is optional. This is because, if there is no configuration of S-measurement in the measurement configuration information for neighbor cell measurement, the terminal device has already started to perform measurement on the neighbor cell when obtaining the measurement configuration information for neighbor cell measurement, and the measurement data obtained by the terminal device when the first condition is met can already be sufficient for the prediction model to perform prediction of the measurement event, without the need to configure the timer and wait for the timer to expire, or the timer can be considered to be configured to 0.

[0076] If the prediction model is trained by the terminal device, the network device can not know the minimum value of the minimum input duration of the prediction model deployed in the terminal device, i.e., the minimum value of the second duration. Therefore, in some implementations, the terminal device can send first information to the network device; correspondingly, the network device receives the first information sent by the terminal device. The first information is used to determine the minimum value of the second duration.

[0077] The first information may, for example, be used to indicate one or more of the following: the minimum value of the second duration; meta information of the prediction model, the meta information including the minimum value of the second duration; an identifier of the prediction model.

[0078] The identifier of the prediction model can also be referred to as a model identifier. In the case where the network device has meta information of multiple models, the network device can determine the meta information of the prediction model from the meta information of the multiple models based on the identifier of the prediction model, and obtain the minimum value of the second duration therefrom.

[0079] Since the minimum input duration and the like of the prediction model can be regarded as the capability of the prediction model, the first information can also be referred to as capability information of the prediction model.

[0080] In some implementations, the first information can be sent in the case where a second condition is met, the second condition including one or more of the following: receiving second information sent by the network device, wherein the second information is used to request the terminal device to send the first information; reaching a periodic sending time of the first information; a change in the moving state of the terminal device. The change in the moving state of the terminal device may, for example, refer to a change in the moving speed of the terminal device, or a cell handover of the terminal device, and the like.

[0081] That is, the terminal device can report the first information to the network device based on a request of the network device, when receiving the second information sent by the network device. Alternatively, the terminal device can periodically send the first information, and the sending period of the first information can be pre-agreed or configured by the network device. Alternatively, the terminal device can report the first information to the network device when its moving state changes, for example, when the terminal device performs cell switching, or when the moving speed of the terminal device changes from low speed to high speed.

[0082] In other implementation manners, the network device can also not configure the terminal device with the above-mentioned timer, but trigger the prediction of the measurement event autonomously by the terminal device after the first condition is met. For example, the terminal device starts to predict the measurement event after a first time length elapses from the time when the first condition is met.

[0083] It can be understood that, for direct prediction, the prediction of the measurement event by the terminal device in step 310, for example, refers to a process that the terminal device directly predicts whether the measurement event will occur in the future based on the measurement value of the RRM measurement, that is, the prediction model is used to predict the occurrence of the measurement event; and for indirect prediction, the prediction of the measurement event by the terminal device in step 310, for example, refers to a process that the terminal device predicts the measurement result in the future based on the measurement value of the RRM measurement and obtains a corresponding predicted value, that is, the prediction model is used to predict the measurement result of the RRM measurement and obtain a corresponding predicted value, and then whether the measurement event will occur in the future can be judged based on the predicted value by using a traditional measurement event judgment method.

[0084] In some implementation manners, the network device can send third information to the terminal device; correspondingly, the terminal device receives the third information sent by the network device. The third information is used to configure the first condition. The third information can also be regarded as configuration information of the first condition.

[0085] The third information is carried in the RRC signaling sent by the network device, for example. The RRC signaling can be an RRC reconfiguration message or an RRC recovery message in related technologies, or can also be a newly defined RRC signaling. The third information can be carried in the measurement configuration information of the RRM measurement, or be transmitted independently of the measurement configuration information.

[0086] The third information may, for example, include one or more of the following: the first condition; a threshold associated with the first condition; a reference signal associated with the first condition; configuration information of the timer.

[0087] The timer is the aforementioned timer used to determine the predicted start time of the measurement event. The threshold associated with the first condition can be, for example, the aforementioned first threshold, second threshold, third threshold, fourth threshold, fifth threshold, and the like. The reference signal associated with the first condition includes, for example, a synchronization signal block / physical broadcast channel block (SS / PBCH block, SSB) and / or a channel state information reference signal (CSI-RS). Different first conditions and / or different threshold values can be configured for different types of reference signals.

[0088] The terminal device determines when to start performing the prediction of the measurement event is described above in connection with FIG. 3. In the following, the terminal device determines when to end the prediction of the measurement event is described in connection with FIG. 4. The method shown in FIG. 3 and the method shown in FIG. 4 can be performed as separate embodiments or can be combined with each other, which is not limited in the present application.

[0089] FIG. 4 is a flow diagram of a wireless communication method according to an embodiment of the present application. As shown in FIG. 4, the method includes step 320.

[0090] In step 320, the terminal device ends the prediction of the measurement event when the third condition is met.

[0091] That is, the third condition is used to trigger the terminal device to end the prediction of the measurement event.

[0092] In this way, unnecessary prediction is ended in time, and the waste of energy and computing resources caused by the terminal device frequently performing the prediction of the measurement event is avoided.

[0093] In some implementations, the third condition is associated with one or more of the following: cell switching; neighbor cell measurement; maximum number of predictions of the measurement event.

[0094] In some implementations, the third condition can include one or more of the following: the terminal device completes the cell switching; the terminal device terminates the neighbor cell measurement; the number of predictions of the measurement event reaches the maximum number of predictions.

[0095] Optionally, if the third condition includes multiple conditions described above, for example, both the terminal device completes the cell switching and the terminal device terminates the neighbor cell measurement, the terminal device can end the prediction of the measurement event when any one of the conditions is met.

[0096] For the condition that the terminal device completes cell switching, the probability of switching again in a short period of time is low, and thus the prediction of the measurement event can be ended after the switching is completed. For the condition that the terminal device terminates the measurement of the neighbor cell, for example, the exit condition of the S measurement (such as the signal quality of the serving cell being greater than a preset threshold value) is met, or the maximum number of measurements of the neighbor cell is reached, at this time, the terminal device cannot obtain the measurement data of the neighbor cell any more, and thus the prediction of the measurement event can be ended. The maximum prediction number of the measurement event refers to the number of times that the terminal device can continuously predict the measurement event, and if the terminal device predicts the measurement event for the maximum prediction number of times and the cell switching does not occur or the measurement event is not predicted to occur, the prediction of the measurement event can be ended.

[0097] In some implementations, the fourth information includes fifth information. The fifth information is used to postpone the end time of the prediction of the measurement event in the case that the prediction number of the measurement event reaches the maximum prediction number.

[0098] If the terminal device has predicted that the measurement event will occur soon, but the prediction number of the measurement event has reached the maximum prediction number, the terminal device can continue to predict based on the fifth information, so as to avoid missing the occurrence of the prediction event and improve the performance of the prediction of the measurement event.

[0099] In some implementations, the fifth information is used to postpone the end time of the prediction of the measurement event to one or more of the following: the time when the terminal device completes the cell switching; the time when the terminal device terminates the measurement of the neighbor cell; the end time of the Mth prediction after the prediction number of the measurement event reaches the maximum prediction number, where M is a positive integer greater than or equal to 1. Here, the end time of the Mth prediction after the prediction number of the measurement event reaches the maximum prediction number refers to that the measurement event is predicted for M times after the prediction number of the measurement event reaches the maximum prediction number. The value of M can be agreed in advance or configured by the network device.

[0100] In some implementations, the network device can send the fourth information to the terminal device; correspondingly, the terminal device receives the fourth information sent by the network device. The fourth information is used to configure the third condition. The fourth information can also be regarded as the configuration information of the third condition.

[0101] The fourth information is carried in the RRC signaling sent by the network device, for example. The RRC signaling can be the RRC reconfiguration message or the RRC recovery message in the related art, or can also be a newly defined RRC signaling. The fourth information can be carried in the measurement configuration information of the RRM measurement, or be transmitted independently of the measurement configuration information.

[0102] The fourth information, and the configuration information of the first timer and the third information described above, can be respectively carried in different RRC signaling, or can be all or partially carried in the same RRC signaling. For the two kinds of information carried in different RRC signaling, the different RRC signaling can be sent at the same time or at different times.

[0103] Based on the above description, in the embodiments of the present application, by setting reasonable trigger conditions and / or termination conditions for the prediction process of the measurement event, the prediction of the measurement event can be timely carried out and / or the unnecessary measurement event prediction can be ended, the waste of energy consumption and computing resources caused by the frequent prediction of the measurement event by the terminal device is avoided, and the burden of the terminal device is reduced.
