[0039] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).
[0040] Mobility Management
[0041] Mobility management is a core process in the control plane process of some communication standards. In some cellular communication systems, mobility management involves switching radio resource control (RRC) connections between different cells.
[0042] To enable handover between cells, the terminal device needs to report measurement reports. Measurement reports can be divided into three types based on the reporting method: periodic reporting; reporting based on measurement events; and reporting based on measurement events and continuing periodic reporting thereafter.
[0043] For example, in second-generation communication systems, measurement reports are always reported at a certain period. Starting from third-generation communication systems, such as WCDMA, and including fourth-generation communication systems LTE and fifth-generation communication systems NR, measurement reports can be reported in any of the three ways mentioned above.
[0044] Regardless of the reporting form of the measurement report, the measurement report may include specific measurement events and / or measurement results. The reported measurement results may include, for example, the signal strength of the cell, or the signal quality. The reported cells may include the current serving cell and the neighboring cells. The objects of measurement may be the same frequency, different frequency or frequency of different communication systems. The signal strength may be represented by the reference signal received power (RSRP) with dBm as the dimension. The signal quality may be represented by the reference signal received quality (RSRQ) with dB as the dimension.
[0045] For the method based on measurement event reporting, the terminal device can report a measurement report in response to a measurement event trigger.
[0046] The triggering of a measurement event may include the following basic elements: measurement results, comparison parameters, and a time to trigger (TTT) timer, which are described below.
[0047] The measurement results may include measurement results of the serving cell and / or neighboring cells. The measurement results may be represented, for example, by the signal strength of the cells.
[0048] The comparison parameter is used to compare whether the measurement result meets the entry condition or the exit condition. The comparison parameter can be represented by one or more of the following: a threshold value, a hysteresis value, an offset value, etc.
[0049] In standard protocols, larger values corresponding to the dimension of a measurement result generally indicate higher signal strength or quality. Based on this, the following describes how to determine whether entry or exit conditions are met when comparison parameters are represented by thresholds, hysteresis values, and offset values.
[0050] For comparison parameters represented by thresholds, absolute comparison can be implemented. Absolute comparison refers to comparing a cell's measurement value with a threshold (i.e., the comparison parameter includes the threshold), (threshold + hysteresis), or (threshold - hysteresis) (i.e., the comparison parameter includes both the threshold and hysteresis). For example, a measurement result greater than (threshold + hysteresis) indicates that the entry condition is met; a measurement result less than (threshold - hysteresis) indicates that the exit condition is met.
[0051] For the case where the comparison parameter is represented by an offset value, a relative comparison can be achieved. Relative comparison can refer to comparing the measurement results of the neighboring cell with the measurement results of the serving cell. Before comparison, each cell can add its own relevant offset value (represented by Of). Among them, the cell-related offset value may include a cell-specific offset value and / or an offset value specific to the frequency where the cell is located. For the serving cell, an offset value related to the corresponding event (represented by Off_event) must also be added. Similar to absolute comparison, when comparing, the hysteresis value (represented by Hys) may need to be considered. Taking the A3 event as an example, assuming that the measurement result is represented by M, the serving cell is marked with s, and the neighboring cell is marked with n, the entry condition and the exit condition can be as follows. Entry condition: Mn+Ofn>Ms+Ofs+Hys+Off_event. Exit condition: Mn+Ofn <Ms+Ofs-Hys+Off_event。
[0052] The TTT timer can be used to ensure the robustness of measurement results. When a cell meets the entry conditions of a certain event, the TTT timer can be started. When the TTT timer times out, if the cell continues to meet the entry conditions of the event, it can indicate that the measurement event corresponding to the cell has been triggered.
[0053] As shown in Figure 2, the measurement results are represented by RSRP, and the gray rectangle represents the measurement result of the target cell. In Figure 2, the TTT timer duration is represented by TTT. The RSRP of the target cell meets the entry criteria at time T0. If the RSRP of the target cell meets the entry criteria within the duration of T0 + TTT, the corresponding measurement event for the target cell is triggered.
[0054] measurement model
[0055] In some communication protocols, such as 3GPP standard specification 38.331 (RRC standard protocol), the measurement results used for measurement event determination are filtered by the RRC layer (Layer 3). However, the initial measurement results within the terminal device are physical layer (Layer 1) measurements of a single beam. Therefore, the process from a single beam measurement result to the triggering of a measurement event can be reflected in the measurement model.
[0056] Figure 3 is an example diagram of a measurement mode. The relevant description of Figure 3 can be referred to 3GPP protocol TS38.331, which will not be repeated here. In the measurement model shown in Figure 3, A 1 Point A represents the layer 1 filtered measurement results of K beams, point B represents the cell quality, point C represents the layer 3 filtered cell quality, point D represents the cell quality reported according to the reporting standard, point E represents the layer 3 filtered measurement results of K beams, and point F represents the quality of the X beams selected for reporting. The aforementioned layer 3 beam-level measurement quality may refer to the quality of the X beams reported at point F in Figure 3, and the layer 3 cell-level measurement quality may refer to the cell quality reported at point D in Figure 3.
[0057] As shown in Figure 3, the beam-based measurement results at layer 1 are first consolidated, where the weighted average of the measurement results of eligible beams in the cell is taken to produce a cell-level measurement result at layer 1. This cell-level measurement result at layer 1 is then iterated through the layer 3 process to obtain the cell measurement result from the aforementioned process.
[0058] Based on the above measurement result generation process and measurement event judgment process, a measurement event starts when the entry condition is met, for example, after TTT time has passed, a measurement event judgment result (for example, including whether the measurement event is triggered) can be given.
[0059] Some standards (such as standard specification 38.133) specify the performance indicators of the measurement results of the terminal equipment, that is, the accuracy of the measurement results. In addition, these standards also specify the length of the measurement period (measurement period) for different measurement scenarios. For example, for intra-frequency measurements in frequency range 1 (FR1), the minimum measurement period is 200ms without discontinuous reception (DRX) and measurement gap. In a measurement period, the terminal device finally samples several measurement results, and how to perform layer 1 filtering on these measurement results is not clearly specified in the standard specification, but is left to the technical implementation. This is the reference point A and A in Figure 3. 1 It should be noted that reference point A 1 The period for generating L1 measurement values is the same as the period for generating L3 filtered measurement values at reference point C.
[0060] As can be seen from the measurement and reporting processes described above, the measurement reports received by network devices contain triggered measurement events. These triggered measurement events are determined based on the measurement results obtained by the terminal device. Making handover decisions based on these measurement reports can lead to numerous issues.
[0061] For example, the triggering event involved in the measurement report obtained by the network device may be a currently triggered event, or, if the delay in sending the measurement report is taken into account, the measurement report includes events that have been triggered in the past. When the network device makes a switching decision based on such a measurement report and starts the switching process, it often leads to "too late switching", that is, the terminal device fails to receive the switching command because the switching action is too slow. This is because during the movement of the terminal device, when the switching command is issued too late, the wireless link of the current service cell will continue to deteriorate. When the target cell of the switching is on another network device, or logically on another central unit (CU), this situation will further worsen the above-mentioned switching process due to the delay caused by the message interaction between the network device where the source cell is located and the network device where the target cell is located. It should be noted that the corresponding to the CU is the distributed unit (DU). A CU can manage multiple DUs, and DUs must exchange information through the CU.
[0062] To address the "too late handover" issue, network equipment can use relaxed parameters for triggering measurement events, allowing terminal devices to trigger measurement events earlier and submit measurement reports earlier. However, due to the complexity of the wireless environment and the uncertainty of terminal device mobility, it is generally difficult to determine the appropriate degree of parameter relaxation in engineering. Some parameter relaxation schemes can lead to "too early handover." This means that when the network equipment sends the handover command to the terminal device, the terminal device has not yet fully entered the target cell, preventing the terminal device from establishing an RRC connection with the target cell, resulting in handover failure.
[0063] FIG4 is a schematic flow chart of a wireless communication method provided by an embodiment of the present application. The method shown in FIG4 can be executed by a terminal device and a network device. The method shown in FIG4 can include step S410.
[0064] Step S410: The terminal device sends a first measurement report.
[0065] The first measurement report may include prediction information of the first measurement event. The prediction information may be obtained through prediction. For example, the first measurement event may be obtained through prediction. In another example, the first measurement report may be obtained through prediction.
[0066] In some embodiments, information related to the first measurement event can be predicted using the first model. That is, the output of the first model can include information related to the first measurement event. The information related to the first measurement event can be the predicted information of the first measurement event.
[0067] In some embodiments, the first measurement report may be predicted by the first model. That is, the output of the first model may include information related to the first measurement report. The information related to the first measurement report may include prediction information of the first measurement event.
[0068] In some embodiments, the first model may predict a measurement result. That is, the output of the first model may include the predicted measurement result. The first measurement event may be determined based on the predicted measurement result. That is, prediction information for the first measurement event may be determined based on the predicted measurement result.
[0069] It should be noted that the predicted measurement result may include one or more of the following predicted measurement results: cell measurement results and beam measurement results. For example, the cell measurement result may include a layer 3 cell measurement result. The beam measurement result may include a layer 1 beam measurement result and / or a layer 3 beam measurement result. The predicted cell measurement result may be obtained from the predicted beam measurement result. For example, the predicted layer 1 beam measurement result may be merged and filtered at layer 3 to become a predicted layer 3 cell measurement result.
[0070] Optionally, the first model may be an artificial intelligence (AI) model. For example, the first model may be a machine learning (ML) model. In another example, the first model may be a neural network model.
[0071] Through the present application, a communication device can predict a first measurement event and / or a first measurement event. For example, a terminal device can make a triggering decision for a measurement event in advance (e.g., before a configured TTT timer expires) and submit a measurement report in advance. Based on this, compared to related technologies, a network device can know the appropriate switching time and switching target earlier, so as to make adequate switching preparations, thereby improving switching performance and switching success rate.
[0072] In some embodiments, the prediction information can be determined based on actual measurement results. That is, the input of the first model can include the actual measurement results. Optionally, the input of the first model can also include historical prediction measurement results. Optionally, the input of the first model can also include other parameters. For example, other parameters can include the historical movement trajectory and / or predicted movement trajectory of the terminal device.
[0073] It should be noted that the measured measurement results may include one or more of the following measurement results actually measured by the terminal device: cell measurement results and beam measurement results. The cell measurement results may include, for example, layer 3 cell measurement results. The beam measurement results may include layer 1 beam measurement results and / or layer 3 beam measurement results.
[0074] The measured measurement result may include a measured measurement result in the time domain. The predicted measurement result may include a predicted measurement result in the time domain. The predicted measurement result in the time domain may be a measurement result at a first moment.
[0075] The predicted measurement result in the time domain may be the measurement result at the second moment. For example, the terminal device may predict the measurement result at the second moment based on the measurement result at the first moment actually measured by the terminal device. That is, the measurement result at the second moment may not be obtained through actual measurement. In this case, the prediction information may be related to the measurement result at the second moment.
[0076] In some embodiments, the predicted measurement results can be used to increase the frequency of the measurement results in the time domain. For example, between adjacent actual measurement results, a prediction can be performed to obtain a predicted measurement result. Based on this, the predicted measurement result can increase the frequency of the measurement results in the time domain.
[0077] Figure 5 illustrates this. As shown in Figure 5, the two curves represent the signal strength of the serving cell and the signal strength of the neighboring cell, respectively. The black dashed line represents the required RRM measurement results for the neighboring cell as specified by the standard protocol specifications, i.e., the actual measurement results. The gray dashed line represents the predicted measurement results for the neighboring cell based on these actual measurement results, i.e., the predicted measurement results. As Figure 5 shows, if both the actual and predicted measurement results are used to determine measurement events, this is logically equivalent to increasing the measurement sampling frequency on the timeline.
[0078] It should be noted that simulations have demonstrated that the predicted measurement results shown in FIG5 can achieve a high degree of accuracy. For example, the mathematical statistical difference (such as the root mean square error (RMSE)) between the predicted measurement results and the measured measurement results can be less than 1 dB.
[0079] It should be noted that, during the training process of the first model, actual measurements need to be performed at these predicted time points to obtain actual measurement values for comparison.
[0080] It is understandable that increasing the sampling frequency can more truly reflect the measurement accuracy of the signal strength of neighboring cell signals in the wireless environment, thereby reducing measurement errors.
[0081] Based on this application, the TTT timer duration may vary, that is, the TTT timer duration actually used by the terminal device may be different from the TTT timer duration configured by the network device. The TTT timer duration configured by the network device may be indicated by the first measurement task described below.
[0082] It should be noted that the TTT timer duration configured by the network device can be understood as not being based on the predicted TTT timer duration, that is, the TTT timer duration specified in the relevant technology.
[0083] In some embodiments, the actual TTT timer duration can be determined based on both the predicted measurement result and the actual measurement result. Continuing with FIG. 5 as an example, the actual TTT timer duration is described. It should be noted that FIG. 5 uses the A3 event as the first measurement event for this purpose, and the present application can also be applied to other types of measurement events.
[0084] As shown in Figure 5, the entry conditions are met at time T0. Based on relevant technologies, within the TTT timer duration (indicated by TTT in Figure 5) configured by the network device, if the entry conditions are met, a measurement event can be triggered. That is, based on relevant technologies, an A3 event can be triggered at time (T0+TTT). Based on the present application, since the sampling frequency of the measurement results is higher, the duration of the TTT timer can be shortened to T*. As can be seen from Figure 5, the (T0+TTT) moment is later than the (T0+TTT*) moment, that is, the present application can trigger the A3 event in advance. In some embodiments, before the terminal device sends the first measurement report, the terminal device can receive a first measurement task sent by the network device. Among them, the first measurement task can be used to configure the prediction and / or reporting of the first measurement event.
[0085] Exemplarily, the first measurement task may include a timing advance, wherein the timing advance may indicate how long in advance the terminal device can predict the first measurement event.
[0086] The time advance can be used to indicate the time range or maximum value that the terminal device predicts the first measurement event can be shortened. If the terminal device does not perform a prediction, the trigger time of the first measurement event is the actual trigger time; if the terminal device performs the prediction proposed in this application, the trigger time of the first measurement event can be the predicted trigger time. The time that can be shortened may refer to the time difference between the predicted trigger time and the actual trigger time. It can be seen that the time advance can be used to indicate the range of the time difference between the predicted trigger time and the actual trigger time; or, the time advance can be used to indicate the maximum value of the time difference between the predicted trigger time and the actual trigger time. The range can be represented by one or more of the parameters such as the maximum value, the minimum value, and the duration.
[0087] In some embodiments, the timing advance can be expressed in one or more of the following units: milliseconds, microseconds, nanoseconds, etc. Alternatively, the timing advance can be expressed in other communication system time parameters. For example, the timing advance can be expressed in the number of SFNs.
[0088] When the TTT timer duration is configured, if the time advance value is greater than the configured TTT timer duration, it may indicate that the terminal device allows the triggering or occurrence of a measurement event to be predicted even if the actual measurement value at the current moment does not meet the entry condition. If the time advance value is less than or equal to the TTT timer duration, it may indicate that the entry condition has been met at the current moment.
[0089] The first measurement task may also include other information. For example, the first measurement task may include one or more of the following: TTT timer duration, layer 3 filter coefficient in the measurement model, and the like.
[0090] In some embodiments, the prediction information of the first measurement event may include one or more of the following: configuration information of the first measurement event, the first information, and the second information.
[0091] In some embodiments, the configuration information for the first measurement event may include identification information for the first measurement task. The configuration information for the first measurement event may be used to indicate which measurement task configured for the network device the prediction information is associated with. Optionally, the identification information for the first measurement task may include any of the following: A1 event, A2 event, A3 event, A4 event, A5 event, A6 event, B1 event, or B2 event. It should be emphasized that A1 to A11 are merely used to logically number events and have no other meaning. Among them, the A1 event may include: the serving cell signal measurement result is higher than an absolute threshold; the A2 event may include: the serving cell signal measurement result is lower than an absolute threshold; the A3 event may include: the neighboring cell signal measurement result is higher than the primary cell (PCell) / primary secondary cell (PSCell) signal measurement result by an offset; the A4 event may include: the neighboring cell signal measurement result is higher than an absolute threshold; the A5 event may include: the PCell / PSCell cell signal measurement result is lower than an absolute threshold 1 and the neighboring cell / secondary cell (SCell) signal measurement result is higher than an absolute threshold 2; the A6 event may include: the neighboring cell signal measurement result is higher than the SCell cell signal measurement result by an offset; the B1 event may include: the neighboring cell measurement result belonging to inter radio access technology (inter RAT) is higher than an absolute threshold; the B2 event may include: the PCell cell signal measurement result is lower than an absolute threshold 1 and the neighboring cell measurement result belonging to Inter RAT is higher than an absolute threshold 2.
[0092] The first information may be used to indicate whether the first measurement event is predicted by the first model. In the case where the first model is an AI model, the first information may be used to indicate whether the first measurement event is predicted by the AI model.
[0093] The second information may be used to indicate measurement information of one or more neighboring cells that triggered the first measurement event. Optionally, the one or more neighboring cells may form a neighboring cell list. The neighboring cell list may be used to indicate measurement information of one or more neighboring cells that triggered the first measurement event.
[0094] The measurement information of the neighboring cell may be related to the predicted measurement result of the neighboring cell. For example, the measurement information of the neighboring cell may include one or more of the following: the measurement result of the neighboring cell, the cell identification information of the neighboring cell, and the time information when the neighboring cell triggers the first measurement event.
[0095] The measurement results of the neighboring cells may include, for example, part or all of the predicted measurement results. Part of the predicted measurement results may include the latest and / or the furthest (ie, the time closest to the current time and / or the time furthest from the current time).
[0096] The measurement result information of the neighboring cells may also include actual measurement results, which may include, for example, the measurement results obtained from the most recent actual measurement.
[0097] In some embodiments, the time information when the neighboring cell triggers the first measurement event may include: timer information of the TTT actually used by the neighboring cell.
[0098] The TTT timer information actually used by the neighboring cell may include: the actual TTT timer duration; or the difference between the actual TTT timer duration and the TTT timer duration configured in the first measurement task. If the terminal device reports the first measurement report when the actually used TTT timer times out, the network device determines the time when the entry condition is met based on the actually used TTT timer information.
[0099] In some embodiments, the neighboring cell measurement information may also include other information about the neighboring cell. For example, the other information about the neighboring cell may include frequency information about the neighboring cell. The frequency information about the neighboring cell may be used to indicate the frequency of the neighboring cell reported in the first measurement report. Based on the frequency information about the neighboring cell, it may be determined at which frequency the measurement event was predicted.
[0100] The cell identification information of the neighboring cell may be used to indicate the identification of the neighboring cell reported in the first measurement report. Based on the identification of the neighboring cell, it may be determined on which cell the measurement event is predicted.
[0101] In some embodiments, a terminal device may receive first configuration information sent by a network device. The first configuration information may be used to configure whether the terminal device is allowed to trigger a first measurement event before the duration specified by a configured TTT timer expires. In other words, the first configuration information may be used to configure whether the TTT timer duration actually used by the terminal device is allowed to be less than the configured TTT timer duration.
[0102] It should be noted that the time advance may implicitly indicate that the terminal device is allowed to trigger the first measurement event before the duration specified by the configured TTT timer expires. That is to say, if the network device is configured with a time advance, it can be considered that the network device allows the terminal device to trigger the first measurement event before the duration specified by the configured TTT timer expires. At this time, the network device may not need to additionally configure whether the terminal device is allowed to trigger the first measurement event before the duration specified by the configured TTT timer expires, that is, the first configuration information may not indicate whether the terminal device is allowed to trigger the first measurement event before the duration specified by the configured TTT timer expires. If the network device is not configured with a time advance, the terminal device may consider that the network device does not allow the terminal device to trigger the first measurement event before the duration specified by the configured TTT timer expires, or the terminal device may determine whether the terminal device is allowed to trigger the first measurement event before the duration specified by the configured TTT timer expires based on the indication of the first configuration information.
[0103] In some embodiments, the network device may configure predicted measurement object information. The predicted measurement object information may indicate at which frequency point or frequency points the terminal device may predict the first measurement event.
[0104] In some implementations, when the network device configures predicted measurement object information, the network device may also configure first measurement object information. The first measurement object information may be used to indicate the measurement object or objects based on which the predicted measurement object is predicted. For example, the first measurement object information indicates MO1, and the predicted measurement object information indicates MO2. In this case, the terminal device may predict whether a measurement event will be triggered in advance on MO2 when the configured TTT timer expires based on the frequency indicated by MO1.
[0105] The network device configuration information (e.g., the first configuration information) can be configured via an RRC message. The RRC message can be used to configure specific control parameters for the measurement task. For example, the RRC message can be used to configure both specific control parameters for the measurement task and the first configuration information. After the terminal device receives the RRC message containing the measurement configuration parameters, the terminal device can perform measurement of the serving cell and the neighboring cell, and report the first measurement report.
[0106] As described above, the prediction of the first measurement event can be determined based on the predicted measurement result. The predicted measurement result can be predicted based on the actual measurement result. In some embodiments, the predicted measurement result can be determined based on the predicted measurement results at other times and / or other frequencies.
[0107] In some embodiments, the predicted measurement result may include one or more measurement results; and / or the measured measurement result may include one or more measurement results.
[0108] For example, the measured measurement result may include one or more measurement results, and the predicted measurement result may include one measurement result. In other words, one or more measurement results may be predicted based on one or more actual measurement results.
[0109] For example, the actual measurement results may include multiple measurement results, and the predicted measurement results may include multiple measurement results. That is, multiple measurement results can be predicted based on multiple actual measurement results. For example, when the terminal device's trajectory is relatively regular, such as when a terminal device in a car is driving along a street, the terminal device can predict measurement results that were not actually measured based on historical measurement results. Predicting multiple measurement results can increase the frequency of measurement results, thereby accelerating the triggering and decision process for measurement events.
[0110] In some embodiments, the terminal device may locally record a variable for the prediction information of the first measurement event and update the variable at an appropriate time. For example, after the TTT timer actually in use expires, the terminal device may update the local variable for recording the prediction information of the first measurement event and send the first measurement report based on the content of the local variable.
[0111] In some embodiments, the actual TTT timer duration used may be determined by the terminal device itself. In some embodiments, the actual TTT timer duration used may be determined based on a duration configured by the network device. In some embodiments, the measurement results may include beam measurement results and / or cell measurement results. For example, the measurement results may include layer 1 beam measurement results. In another example, the measurement results may include layer 3 beam measurement results. In another example, the measurement results may include layer 3 cell measurement results.
[0112] When the measurement results include Layer 1 beam measurements, the measurement model can be as shown in Figure 6. In the measurement model shown in Figure 6, the input to the first model can include the L1 beam measurement results of the terminal device at one or more time points and one or more auxiliary parameters. The output of the first model can include a predicted L1 beam measurement result for a particular beam at a particular time point. This predicted L1 beam measurement result and the actual L1 beam measurement result measured by the terminal device can be used in the calculation process of subsequent modules.
[0113] In the case where the predicted measurement results include layer 1 beam measurement results, the actual layer 3 filter coefficient can be the layer 3 filter coefficient configured for the first measurement task multiplied by the shrinkage coefficient. The shrinkage coefficient can be greater than 0 and less than 1. For example, the layer 3 filter coefficient configured for the first measurement task can be represented by a, and the shrinkage coefficient can be represented by scaling. The shrinkage coefficient actually used is a'=a*scaling. The design of this technical solution mainly takes into account: assuming that the measurement result is predicted, there will always be a certain difference in accuracy compared with the actual measurement result. This application can reduce the impact of the latest measurement result on the cell-level L3 measurement result after the total L3 filtering by reducing the filter coefficient.
[0114] For example, when the measurement model shown in FIG6 is used, the layer 3 filter coefficient may be multiplied by the shrinkage coefficient.
[0115] Optionally, the shrinkage factor may satisfy one or more of the following: protocol provisions, predetermined, preset value, network device configuration, and self-determination by the terminal device.
[0116] When the measurement results include Layer 3 cell measurement results, the measurement model may be as shown in Figure 7. In the measurement model shown in Figure 7, the first model's parameters may include: L3 filtered cell measurement results at one or more time points, as well as one or more other auxiliary parameters. The output of the first model may include: L3 cell measurement results.
[0117] In some embodiments, the terminal device may receive second configuration information. The second configuration information may be used to configure one or more of the following: whether one or more measurement results included in the predicted measurement results include beam measurement results and / or cell measurement results; and whether one or more measurement results included in the measured measurement results include beam measurement results and / or cell measurement results.
[0118] It is understood that the measured measurement results can serve as the input of the first model, and the predicted measurement results can serve as the output of the first model. Therefore, the second configuration information can be used to configure the input and / or output of the first model. Alternatively, the second configuration information can be used to configure the algorithm structure of the first model. The algorithm structure of the first model may, for example, include one or more of the following: input parameters including layer 1 beam measurement results, input parameters including layer 3 cell measurement results, output parameters including layer 1 beam measurement results, and output parameters including layer 3 cell measurement results. For example, the algorithm structure of the first model may be the algorithm structure shown in Figure 6 or Figure 7.
[0119] It should be noted that the measurement model shown in FIG6 or FIG7 may be part of the measurement model, that is, the actual measurement model may also include other modules. Some modules in the measurement model shown in FIG6 or FIG7 may also be deleted or replaced by other modules.
[0120] It should be noted that the above embodiment mainly describes the technical solution such as the process and configuration of predicting the first measurement event, and the technical solution can also be applied to the process and configuration of predicting the first measurement report.
