[0042] In order to more clearly understand the embodiments of the present application, first, some related background knowledge is introduced as follows.
[0043] I. Non-connected state measurement relaxation
[0044] According to the location and movement state, the non-connected state (RRC_IDLE / INACTIVE) terminal relaxes the measurement according to certain decision criteria. The decision criteria mainly include whether the user equipment (UE) is low mobility and whether the UE is at the cell edge, and the related configuration is broadcast in the system information block 2 (SIB2).
[0045] The measurement relaxation criterion of low mobility: the reference signal received power (RSRP) drop is less than the threshold within a certain time, or even rises, and then the measurement relaxation is selected.
[0046] (SrxlevRef-Srxlev)<S SearchDeltaP for a period of T SearchDeltaP
[0047] Wherein, Srxlev represents the S value of the current serving cell, and the specific calculation can refer to the cell selection and reselection process;
[0048] Srxlev Ref The reference S value of the current serving cell is represented, and the specific setting method of the reference S value is: at the moment when the UE completes the cell selection or reselection, that is, at the moment when the UE completes the camping in the new cell, the reference S value is assigned to the current S value; then in the subsequent measurement process, if the S value is greater than the reference S value, the reference S value is immediately updated to the larger current S value; if the above criterion is met, but it cannot be maintained for T SearchDeltaP for a long time, the reference S value is also updated to the current S value;
[0049] S SearchDeltaP The configured RSRP drop threshold value is represented;
[0050] T SearchDeltaP The configured specific time length is represented.
[0051] The measurement relaxation criterion of not being at the cell edge: when the terminal is not at the cell edge (still in the good coverage area of the cell), the measurement relaxation is selected.
[0052] Srxlev>S SearchThresholdP , and Squal>S SearchThresholdQ (if S SearchThresholdQ is configured)
[0053] When the above criteria are met, the corresponding measurement is relaxed. For example, for intra-frequency measurement, the terminal will multiply the measurement period by a relaxation factor K1 = 3, that is, the measurement period is increased to 3 times. For inter-frequency measurement, the measurement period is enlarged by a factor M2 relative to the Discontinuous Reception (DRX) cycle, which is fixed at 1.5 (originally 1.5 or 1).
[0054] II. Redcap UE connected state radio resource management (RRM) measurement relaxation
[0055] Similar to the low mobility criterion in the non-connected state, the difference is:
[0056] (1) The base station sends the falling threshold value and a specific time length to the UE through dedicated signaling;
[0057] (2) If the serving cell RSRP drop value is lower than the threshold and the duration exceeds the threshold, the terminal does not directly relax the measurement, but sends UE Assistance Information (UAI) feedback to indicate that the measurement relaxation condition is met, that is, rrm-MeasRelaxationFulfilment is true.
[0058] III. Measurement gap
[0059] If the UE needs to perform inter-frequency measurement (including inter-standard measurement), a simple way is to install 2 kinds of radio frequency receivers in the UE device to measure the frequency points of the current cell and the target cell respectively, but this will bring the problem of cost increase and mutual interference between different frequency points. Therefore, 3GPP proposes a measurement gap (GAP) method, that is, a part of time (i.e. measurement GAP time) is reserved, during which the UE will not send and receive any data, and the receiver will be adjusted to the target cell frequency point to perform inter-frequency measurement, and then switch back to the current cell after the GAP time ends.
[0060] The measurement gap configuration parameters mainly include length (such as 1ms), period (such as 20ms), and the UE can perform periodic measurement within the measurement gap.
[0061] The terminal measurement provided by the embodiments of the present application will be described in detail in combination with some embodiments and their application scenarios.
[0062] The prediction method provided in the embodiments of the present application can be applied to a terminal measurement scenario. A terminal acquires a first parameter. The terminal can determine whether to predict a cell signal quality based on the first parameter, and obtain a predicted value. Since the terminal can predict the cell signal quality, the terminal measurement of the cell signal quality is reduced, and the measurement overhead of the terminal measurement is reduced.
[0063] FIG. 2 is a flowchart of a prediction method provided in the embodiments of the present application. As shown in FIG. 2, the method includes steps 201-202.
[0064] In step 201, a terminal acquires a first parameter.
[0065] It should be noted that the embodiments of the present application can be applied to a terminal measurement scenario. The terminal includes, but is not limited to, the types of the terminal 11 listed above. The network side device includes, but is not limited to, the types of the network side device 12 listed above. The embodiments of the present application are not limited in this regard. The terminal supports a prediction-based measurement relaxation function. The terminal can report to the network side device that the terminal supports the prediction-based measurement relaxation function.
[0066] The terminal can acquire the first parameter according to a network side device broadcast. The terminal can also acquire the first parameter by receiving the first parameter sent by the network side device through an RRC message. The first parameter is related to terminal measurement.
[0067] In step 202, the terminal determines whether to predict a cell signal quality based on the first parameter, and obtains a predicted value.
[0068] The cell is a camping cell, a serving cell and / or a neighbor cell. The cell signal quality is, for example, a reference signal received power (RSRP), a signal to interference plus noise ratio (SINR) or a reference signal received quality (RSRQ).
[0069] After the terminal acquires the first parameter, the terminal can determine whether to predict the cell signal quality at a measurement gap corresponding to a measurement gap period or a time point corresponding to a measurement period according to the first parameter, and obtain a predicted value. That is, when the terminal determines that the cell signal quality can be predicted, the terminal does not perform actual measurement of the cell signal quality at the measurement gap corresponding to the measurement gap period or the time point corresponding to the measurement period. The terminal measurement of the cell signal quality is reduced, and the measurement overhead of the terminal measurement is reduced.
[0070] Optionally, the predicted value is obtained by the terminal based on an Artificial Intelligence (AI) model.
[0071] Optionally, since the terminal can determine to predict the cell signal quality at a time point corresponding to a measurement gap period or a measurement period, the network side device can reduce the configuration of the corresponding measurement gap and improve the time domain length of scheduling the terminal, thereby improving the rate of the terminal.
[0072] In the prediction method provided by the embodiments of the present application, the terminal obtains the first parameter, and the terminal can determine whether to predict the cell signal quality based on the first parameter to obtain a predicted value. Since the terminal can predict the cell signal quality, the terminal can reduce the measurement of the cell signal quality, thereby reducing the measurement overhead of frequent measurement of the terminal.
[0073] Optionally, the first parameter comprises at least one of the following:
[0074] (1) first indication information, used for whether to predict the cell signal quality, or used for indicating whether to use a first rule to predict the cell signal quality, or used for indicating whether the network side device allows the terminal to request configuration information for predicting the cell signal quality. The terminal can predict the cell signal quality based on the first indication information, for example, the terminal can use the AI model to relax the measurement based on the first indication information, that is, the terminal can use the predicted value of the AI model prediction reasoning as the actual measurement value of the cell signal quality, thereby reducing the measurement of the cell signal quality of the terminal.
[0075] (2) a cell signal quality measurement value threshold. The cell signal quality measurement value threshold is used to determine whether to predict the cell signal quality, for example, to use the AI model to relax the measurement reasoning of the cell signal quality, for example, when the RSRP measurement value actually measured by the terminal is greater than or equal to the cell signal quality measurement value threshold, the terminal starts the AI model and uses the AI model to relax the measurement reasoning of the cell signal quality, uses the predicted value of the AI model prediction reasoning as the actual measurement value of the cell signal quality, and reduces the measurement of the cell signal quality of the terminal.
[0076] (3) A cell signal quality change amount threshold value, used to determine whether to predict the cell signal quality, for example, to use an AI model to relax the inference of the cell signal quality measurement. For example, when the actual RSRP measurement of the terminal in the first time length decreases by less than or equal to the cell signal quality change amount threshold value, the terminal starts the AI model and uses the AI model to relax the inference of the cell signal quality measurement, and uses the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, to reduce the measurement of the terminal. It should be noted that the actual RSRP measurement of the terminal decreases in the first time length, indicating that the terminal is moving away from the network side device, and the terminal can start the AI model to relax the inference of the measurement.
[0077] (4) The first time length, indicating the time length corresponding to the change amount of the cell signal quality measurement, that is, the time length of the actual cell signal quality measurement of the terminal.
[0078] (5) Model parameters, indicating the parameters of the artificial intelligence AI model used to predict the cell signal quality. Optionally, the model parameters include at least one of the following: model identifier, model structure information, and model parameter information.
[0079] (6) A cell signal quality prediction value, used to determine whether to predict the cell signal quality, for example, to use an AI model to relax the inference of the cell signal quality measurement. For example, when the RSRP prediction value of the AI model prediction inference is greater than the cell signal quality prediction value threshold value, the terminal determines to use the AI model to predict the cell signal quality.
[0080] (7) A cell signal quality change amount threshold value, used to determine whether to predict the cell signal quality, for example, to use an AI model to relax the inference of the cell signal quality measurement. For example, when the decrease amount of the RSRP prediction value of the AI model inference in the second time length is less than the cell signal quality prediction, the terminal determines to use the AI model to predict the cell signal quality.
[0081] (8) The second time length, indicating the time length corresponding to the change amount of the cell signal quality prediction.
[0082] (9) A prediction accuracy threshold. For example, the terminal determines whether to select the measurement relaxation based on the AI model based on the prediction accuracy threshold. For example, in the non-connected state, the terminal can select the AI based measurement relaxation or the legacy measurement relaxation scheme according to the prediction accuracy threshold. The terminal can determine to select the AI based measurement relaxation based on the actual measured RSRP measurement value and the AI model inferred RSRP prediction value, or the terminal can determine to select the AI based measurement relaxation based on the actual measured RSRQ measurement value and the AI model inferred RSRQ prediction value. For example, the prediction accuracy threshold is a root mean square error (RMSE) threshold, the terminal can determine a target value based on the actual measured RSRP measurement value and the AI model inferred RSRP prediction value, the target value is the RMSE, when the target value is less than the prediction accuracy threshold, the terminal selects the AI based measurement relaxation, or when the target value is not less than the prediction accuracy threshold, the terminal selects the AI based measurement relaxation.
[0083] It should be noted that the above prediction of the cell signal quality according to the AI model can be based on the historical measurement of the cell signal quality and the like. The method of predicting the cell signal quality is not limited to using the AI model, and other prediction methods are also within the scope of the present application.
[0084] Optionally, the first parameter can be configured in the measurement reporting configuration ReportConfig or OtherConfig, and the terminal obtains the first parameter in the form of broadcasting or sending the configuration information by the network side device.
[0085] Optionally, the specific implementation of the step 202 includes at least one of the following:
[0086] (a) The terminal determines whether to predict the cell signal quality according to the first indication information in the first parameter.
[0087] The terminal can determine whether to predict the cell signal quality according to the first indication information in the first parameter.
[0088] (b) The terminal predicts the cell signal quality when the first parameter meets the preset condition.
[0089] The preset condition is configured by the network side device to the terminal based on the first parameter. The terminal determines whether the first parameter satisfies the preset condition. In the case that the first parameter satisfies the preset condition, the terminal can predict the cell signal quality. The terminal does not need to perform actual measurement on the cell signal quality at the time point of predicting the cell signal quality or the measurement gap, thereby reducing the measurement of the terminal on the cell signal quality, and reducing the measurement overhead of the terminal. Meanwhile, the network side device can schedule the terminal without performing actual measurement on the cell signal quality at the time point of predicting the cell signal quality or the measurement gap, thereby improving the rate of the terminal.
[0090] (c) The terminal measures the cell signal quality when the first parameter does not satisfy the preset condition.
[0091] When the first parameter does not satisfy the preset condition, the terminal needs to perform actual measurement on the cell signal quality, and the terminal performs measurement according to the conventional measurement mode.
[0092] Optionally, the preset condition comprises at least one of the following:
[0093] (a) The cell signal quality measurement value measured by the terminal is greater than or equal to the cell signal quality measurement value threshold.
[0094] When the actual measurement value of the cell signal quality measured by the terminal is greater than or equal to the cell signal quality measurement value threshold, the terminal can predict the cell signal quality. For example, the terminal can start the AI model, and use the AI model to perform relaxed inference on the cell signal quality, take the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform relaxed inference on the cell signal quality, thereby reducing the measurement of the terminal.
[0095] (b) The decrease amount of the cell signal quality measurement value measured by the terminal within the first time length is less than or equal to the cell signal quality change amount threshold.
[0096] When the decrease amount of the actual measurement value of the cell signal quality measured by the terminal within the first time length is less than or equal to the cell signal quality change amount threshold, the terminal can predict the cell signal quality. For example, the terminal can start the AI model, and use the AI model to perform relaxed inference on the cell signal quality, take the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform relaxed inference on the cell signal quality, thereby reducing the measurement of the terminal.
[0097] (c) The predicted value is greater than or equal to the cell signal quality prediction value threshold.
[0098] The terminal can predict the cell signal quality when the predicted value obtained by predicting the cell signal quality is greater than or equal to a cell signal quality prediction value threshold. For example, the terminal can perform AI model-based measurement relaxation, i.e., taking the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform measurement relaxation inference on the cell signal quality to reduce the measurement of the terminal, when the RSRP predicted value of the AI model prediction inference is greater than or equal to the cell signal quality prediction value threshold.
[0099] (d) the amount of decrease in the cell signal quality prediction value within the second time length is less than or equal to the cell signal quality prediction change amount threshold.
[0100] The terminal can predict the cell signal quality when the amount of decrease in the cell signal quality prediction value of the AI model inference within the second time length is less than or equal to the cell signal quality prediction change amount threshold. For example, the terminal can perform AI model-based measurement relaxation, i.e., taking the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform measurement relaxation inference on the cell signal quality to reduce the measurement of the terminal, when the RSRP predicted value of the AI model prediction inference within the second time length is less than or equal to the cell signal quality prediction change amount threshold.
[0101] (e) the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is less than or equal to the prediction accuracy threshold.
[0102] The target value can be RMSE, and when the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is less than the prediction accuracy threshold, the terminal can select AI model-based measurement relaxation, i.e., taking the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform measurement relaxation inference on the cell signal quality to reduce the measurement of the terminal.
[0103] (f) the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is greater than the prediction accuracy threshold.
[0104] When the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is greater than the prediction accuracy threshold, the terminal can select AI model-based measurement relaxation, i.e., taking the predicted value of the AI model prediction inference as the actual measurement value of the cell signal quality, or the terminal can use the first rule to perform measurement relaxation inference on the cell signal quality to reduce the measurement of the terminal.
[0105] Optionally, in the case of predicting the cell signal quality, the method further comprises any one of the following:
[0106] When the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is greater than the prediction accuracy threshold, the terminal sends prediction failure information to the network side device; when the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value is less than or equal to the prediction accuracy threshold, the terminal sends prediction failure information to the network side device.
[0107] As a possible implementation, the target value can be RMSE. In the case of predicting the cell signal quality, when the target value determined based on the cell signal quality measurement value measured by the terminal and the cell signal quality prediction value predicted by the AI model inference is greater than the prediction accuracy threshold, it indicates that the cell signal quality prediction value predicted by the AI model inference is inaccurate, and then the terminal fallbacks to the conventional legacy measurement relaxation, the terminal records this event, and generates a first report; the first report includes the prediction failure information. The terminal sends the prediction failure information to the network side device, and the network side device can obtain the prediction failure information and optimize the AI model based on the prediction failure information or not allow the terminal to relax the measurement based on the AI model.

The terminal can take the minimum value between the maximum relaxation multiple configured by the network-side device and the predicted value obtained by the inference of the AI model used for predicting the cell signal quality as the relaxation multiple.
[0147] The terminal can multiply the measurement period and the relaxation multiple based on the relaxation multiple and the measurement period to obtain a new measurement period, the new measurement period being greater than the measurement period before multiplication, so that the measurement period is increased, actual measurement is performed at a target time point corresponding to the measurement period, and prediction of the cell signal quality is performed at other time points corresponding to the measurement period except the target time point; the target time point is a measurement time point after the measurement period is increased.

[0150] FIG. 3 is a flowchart of a prediction method according to an embodiment of the present application, as shown in FIG. 3, the method comprises step 301; wherein:
[0151] In step 301, the network-side device configures a first parameter for the terminal; the first parameter is used by the terminal to determine whether to predict the cell signal quality to obtain a predicted value according to the first parameter.
[0152] The cell is a camping cell, a serving cell, and / or a neighbor cell, and the cell signal quality is, for example, RSRP, SINR, or RSRQ.
[0153] The network-side device configures the first parameter for the terminal. The network-side device configures the first parameter for the terminal through broadcasting or an RRC message, so that the terminal obtains the first parameter. The first parameter is related to terminal measurement. After receiving the first parameter, the terminal can determine whether to predict the cell signal quality in the measurement gap corresponding to the measurement gap period or the time point corresponding to the measurement period according to the first parameter, to obtain a predicted value. That is, in the case where the terminal determines that the cell signal quality can be predicted, the terminal can not actually measure the cell signal quality at the measurement gap corresponding to the measurement gap period or the time point corresponding to the measurement period, thereby reducing the measurement of the terminal on the cell signal quality and reducing the measurement overhead of the terminal measurement.
[0154] Optionally, the predicted value is obtained based on an artificial intelligence (AI) model.
[0155] Optionally, since the terminal can determine to predict the cell signal quality in the measurement gap corresponding to the measurement gap period or the time point corresponding to the measurement period, the network-side device can reduce the configuration of the corresponding measurement gap, improve the time domain length of scheduling the terminal, and improve the rate of the terminal.
[0156] In the prediction method provided by the embodiments of the present application, the network-side device configures the first parameter for the terminal. The first parameter is used for the terminal to determine whether to predict the cell signal quality based on the first parameter, to obtain a predicted value. Since the terminal can predict the cell signal quality, the measurement of the terminal on the cell signal quality is reduced, thereby reducing the measurement overhead of frequent measurement of the terminal.
[0157] Optionally, the first parameter comprises at least one of the following:
[0158] (1) first indication information, used for whether to predict the cell signal quality, or used for indicating whether to use a first rule to predict the cell signal quality, or used for indicating whether the network-side device allows the terminal to request configuration information for predicting the cell signal quality. The terminal can predict the cell signal quality based on the first indication information. For example, the terminal can use an AI model to relax measurement based on the first indication information. That is, the terminal can use the predicted value of AI model prediction reasoning as the actual measurement value of the cell signal quality, thereby reducing the measurement of the terminal on the cell signal quality.
[0159] (2) A cell signal quality measurement value threshold. The cell signal quality measurement value threshold is used to determine whether to use an AI model to predict the cell signal quality, that is, to use the AI model to relax the inference of the cell signal quality measurement. For example, when the RSRP measurement value actually measured by the terminal is greater than or equal to the cell signal quality measurement value threshold, the terminal starts the AI model and uses the AI model to relax the inference of the cell signal quality measurement, and the predicted value of the AI model prediction inference is taken as the actual measurement value of the cell signal quality, thereby reducing the measurement of the terminal.
[0160] (3) A cell signal quality change threshold. The cell signal quality change threshold is used to determine whether to use an AI model to predict the cell signal quality, that is, to use the AI model to relax the inference of the cell signal quality measurement. For example, when the decrease amount of the RSRP actually measured by the terminal in the first time length is less than or equal to the cell signal quality change threshold, the terminal starts the AI model and uses the AI model to relax the inference of the cell signal quality measurement, and the predicted value of the AI model prediction inference is taken as the actual measurement value of the cell signal quality, thereby reducing the measurement of the terminal. It should be noted that the decrease of the RSRP actually measured by the terminal in the first time length indicates that the terminal is moving away from the network side device, and the terminal can start the AI model to relax the inference of the measurement.
[0161] (4) A first time length, indicating a time length corresponding to a cell signal quality measurement change amount, that is, a time length of actually measuring the cell signal quality by the terminal.
[0162] (5) Model parameters, indicating parameters of an artificial intelligence AI model used to predict the cell signal quality. Optionally, the model parameters include at least one of the following: a model identifier, model structure information, and model parameter information.
[0163] (6) A cell signal quality prediction value, used to determine whether to use an AI model to predict the cell signal quality, that is, to use the AI model to relax the inference of the cell signal quality measurement. For example, when the RSRP prediction value of the AI model prediction inference is greater than the cell signal quality prediction value threshold, the terminal determines to use the AI model to predict the cell signal quality.
[0164] (7) A cell signal quality change threshold, used to determine whether to use an AI model to predict the cell signal quality, that is, to use the AI model to relax the inference of the cell signal quality measurement. For example, when the decrease amount of the RSRP prediction value of the AI model inference in the second time length is less than the cell signal quality prediction, the terminal determines to use the AI model to predict the cell signal quality.
[0165] (8) A second time length, indicating a time length corresponding to a cell signal quality prediction change amount.
[0166] (9) a prediction accuracy threshold. The prediction accuracy threshold is used to indicate whether the terminal selects the measurement relaxation based on the AI model, i.e., in the non-connected state, the terminal can select the AI based measurement relaxation or the legacy measurement relaxation scheme according to the prediction accuracy threshold. The terminal can determine to select the AI based measurement relaxation based on the actual measured RSRP measurement value and the AI model inferred RSRP prediction value, or the terminal can determine to select the AI based measurement relaxation based on the actual measured RSRQ measurement value and the AI model inferred RSRQ prediction value. For example, the prediction accuracy threshold is a root mean square error (RMSE threshold), the terminal can determine a target value based on the actual measured RSRP measurement value and the AI model inferred RSRP prediction value, the target value is the RMSE, when the target value is less than the prediction accuracy threshold, the terminal selects the AI based measurement relaxation, or when the target value is not less than the prediction accuracy threshold, the terminal selects the AI based measurement relaxation.

[0173] (e) a preset proportion; the preset proportion can be a proportion of measuring and predicting the cell signal quality in a measurement gap period, or a proportion between the reporting number of measurement values and the reporting number of AI model predicted values, i.e., the preset proportion can be the reporting number of measurement values / total reporting number, the reporting number of AI model predicted values / total reporting number, or the reporting number of measurement values / the reporting number of AI model predicted values, all of which are used to represent the proportion between the reporting number of measurement values and the reporting number of predicted values. The preset proportion can be indicated in the reporting configuration ReportConfig, and represented by a fraction, for example, the preset proportion is 1 / 3, which means that the reporting number of AI model predicted values accounts for 1 / 3 of the total reporting number, i.e., 2 times of actual measurement values are reported in the measurement gap period, and 1 time of predicted values is reported.
[0174] (f) a first rule; the first rule is used for the terminal to predict the cell signal quality.

[0207] Next, the prediction method provided by the embodiments of the present application is further described through specific embodiments.
[0208] Embodiment one: measurement relaxation of the non-connected state terminal
[0209] Step 1: The network-side device broadcasts first parameters, and the first parameters include at least one of the following:
[0210] First indication information, used to indicate whether to predict the cell signal quality, or to indicate whether to predict the cell signal quality by using the first rule, or to indicate whether the network-side device allows the terminal to request configuration information for predicting the cell signal quality;
[0211] A cell signal quality measurement value threshold value is used to determine whether the AI model is used to predict the cell signal quality, i.e., the AI model is used to relax the measurement inference of the cell signal quality.
[0212] A cell signal quality change threshold value is used to determine whether the AI model is used to predict the cell signal quality, i.e., the AI model is used to relax the measurement inference of the cell signal quality.
[0213] A first time length indicates a time length corresponding to the cell signal quality measurement change. For example, when the RSRP drop measured by the terminal within the first time length is less than or equal to the cell signal quality change threshold value, the AI model is started, and the AI model is used to relax the measurement inference of the cell signal quality.
[0214] A model parameter indicates a parameter of an artificial intelligence AI model used to predict the cell signal quality. The model parameter includes a model identifier, model structure information, and model parameter information.
[0215] A cell signal quality measurement value threshold value is used to determine whether the AI model is used to predict the cell signal quality, i.e., the AI model is used to relax the measurement inference of the cell signal quality. For example, when the RSRP prediction value inferred by the AI model is greater than or equal to the cell signal quality measurement value threshold value, the terminal determines to use the AI model to predict the cell signal quality.
[0216] A cell signal quality change threshold value is used to determine whether the AI model is used to predict the cell signal quality, i.e., the AI model is used to relax the measurement inference of the cell signal quality.
[0217] A second time length indicates a time length corresponding to the cell signal quality prediction change. For example, when the drop of the RSRP prediction value inferred by the AI model within the second time length is less than or equal to the cell signal quality change threshold value, the terminal determines to use the AI model to predict the cell signal quality.
[0218] A prediction accuracy threshold value is used to indicate whether the terminal selects the AI based measurement relaxation. If the AI model inference includes the RSRP or RSRQ prediction value, the terminal simultaneously performs actual measurement and AI model prediction in the measurement gap, determines a target value according to the actual measurement value and the prediction value, the target value is the RMSE, and selects the AI based or legacy measurement relaxation scheme according to the prediction accuracy threshold value.
[0219] Step 2, the terminal performs model inference, and performs measurement relaxation based on the first parameter.
[0220] The relaxation multiple of the measurement relaxation can be a fixed value or an AI model prediction value. In particular, the network side device can configure a maximum relaxation multiple, and the terminal performs measurement relaxation based on the minimum value of the prediction value obtained by the AI model inference on the cell signal quality and the maximum relaxation multiple configured by the network side device.
[0221] Step 3, if the network side device configures a prediction accuracy threshold, and the terminal performs model inference, and determines that the target value based on the RSRP measurement value measured by the terminal and the RSRP prediction value of the AI model inference is less than or equal to, or greater than the prediction accuracy threshold, i.e. the prediction accuracy threshold is not satisfied, the terminal fallbacks to legacy measurement relaxation, and the terminal records this event and generates a first report, the first report includes prediction failure information, and the prediction failure information includes at least one of the following:
[0222] AI model identification for predicting the cell signal quality;
[0223] Cell identification, i.e. the serving cell in which the terminal resides when the AI model prediction fails;
[0224] Prediction failure reason, for example, the accuracy of the AI model prediction does not meet the prediction accuracy threshold requirement, such as the RMSE does not meet the prediction accuracy threshold requirement.
[0225] Step 4: After the terminal enters the connected state, the network side device obtains the first report (i.e. inference failure report), optimizes the AI model or does not allow the terminal to perform AI model based measurement relaxation.
[0226] Embodiment two, connected state terminal measurement reduction (network side device configures a first rule)
[0227] Step 0, the terminal reports support for prediction based connected state measurement reduction function.
[0228] Step 1, the network side device sends a first parameter, the first parameter includes at least one of the following:
[0229] Cell signal quality measurement value threshold, used to determine whether to use an AI model to predict the cell signal quality, i.e. to use an AI model to perform measurement relaxation inference on the cell signal quality. For example, when the RSRP measurement value measured by the terminal in the serving cell is greater than or equal to the cell signal quality measurement value threshold, the terminal can perform measurement relaxation inference on the cell signal quality using the first rule to reduce the terminal's measurement.
[0230] a cell signal quality change threshold, used to determine whether to use the AI model to predict the cell signal quality, i.e., to use the AI model to relax the inference of the cell signal quality measurement.
[0231] a first time length, representing the time length corresponding to the cell signal quality measurement change. For example, if the amount of decrease in the RSRP measurement value measured by the terminal in the serving cell within the first time length is less than or equal to the cell signal quality change threshold, the terminal can use the first rule to relax the inference of the cell signal quality measurement, and reduce the measurement of the terminal.
[0232] a prediction accuracy threshold, used by the terminal to determine whether to select the AI model-based measurement relaxation. If the model inference includes the RSRP or RSRQ prediction value, the terminal simultaneously performs actual measurement and AI model prediction in the measurement gap, determines the target value according to the actual measurement value and the prediction value, the target value is the RMSE, and determines whether the terminal can use the first rule to relax the inference of the cell signal quality measurement according to the prediction accuracy threshold, and reduce the measurement of the terminal.
[0233] In particular, the above parameters can be indicated in the measurement reporting configuration ReportConfig.
[0234] The first rule includes at least one of the following:
[0235] 1) The terminal predicts the cell signal quality at the target frequency point.
[0236] 2) The terminal measures the cell signal quality at a part of the target frequency point, and predicts the cell signal quality at another part of the target frequency point.
[0237] When the number of target frequency points is multiple, the terminal can actually measure the cell signal quality at a part of the target frequency points, and predict the cell signal quality at another part of the target frequency points, for example, use the AI model to predict the cell signal quality at another part of the target frequency points, and use the prediction value obtained by the AI model as the prediction value of another part of the frequency points. Among them, another part of the frequency points can be indicated in the measurement target MeasObjectNR configured by the network side device.
[0238] 3) The terminal predicts the cell signal quality at the target cell.
[0239] 4) The terminal measures the cell signal quality of a part of the target cells, and predicts the cell signal quality of another part of the target cells.
[0240] When the number of target cells is multiple cells, the terminal can actually measure the cell signal quality of a part of the target cells, and predict the cell signal quality of another part of the target cells, for example, use an AI model to predict the cell signal quality of another part of the target cells, and take the predicted value obtained by the AI model as the predicted value of another part of the cells; wherein another part of the cells is indicated by a cell list in the measurement target MeasObjectNR configured by the network side device, that is, which cells in the cell list perform AI model prediction.
[0241] 5) The terminal predicts the cell signal quality in the target beam pair.
[0242] 6) The terminal measures the cell signal quality in a part of the target beams, and predicts the cell signal quality in another part of the target beams.
[0243] When the number of target beams is multiple beams, the terminal can actually measure the cell signal quality in a part of the target beams, and predict the cell signal quality in another part of the target beams, for example, use an AI model to predict the cell signal quality of another part of the target beams, and take the predicted value obtained by the AI model as the predicted value of another part of the beams; wherein another part of the beams is indicated in the measurement target MeasObjectNR, and another part of the beams can be associated with the target cell.
[0244] 7) The terminal predicts the cell signal quality in the corresponding measurement gap configuration identified by the measurement gap configuration identifier according to the pattern period and / or the pattern bitmap.
[0245] The terminal measures the cell signal quality in a part of the measurement gap corresponding to the pattern period and / or the pattern bitmap, and predicts the cell signal quality in another part of the measurement gap in the corresponding measurement gap configuration identified by the measurement gap configuration identifier.
[0246] 8) The terminal predicts the cell signal quality based on the preset proportion.
[0247] The cell signal quality is measured by a preset proportion in a measurement gap period corresponding to the measurement gap, wherein the preset proportion can be a proportion of measurement and prediction of the cell signal quality in the measurement gap period, or a proportion between the reporting number of the measurement value and the reporting number of the AI model prediction value, i.e., the reporting number of the measurement value / total reporting number, the reporting number of the AI model prediction value / total reporting number, or the reporting number of the measurement value / the reporting number of the AI model prediction value, which are all used to represent the proportion between the reporting number of the measurement value and the reporting number of the prediction value. The preset proportion can be indicated in the reporting configuration ReportConfig by a fraction, for example, the preset proportion is 1 / 3, which means that the reporting number of the AI model prediction value of the terminal accounts for 1 / 3 of the total reporting number, i.e., 2 times of the actual measurement value is reported in the measurement gap period and 1 time of the prediction value is reported.
[0248] Step 2: In the case that the first parameter meets the preset condition, the terminal predicts the cell signal quality based on the first rule and reports.
[0249] Step 3: The network can obtain the actual measurement requirement of the terminal according to the first rule, and reduce the MG time domain configuration. The reduction of the MG time domain configuration can be realized by a specific MG pattern.
[0250] Measurement gap configuration identifier;
[0251] Pattern period, which can be an integer multiple of the original measurement gap MG period, or a specific length, such as ms;
[0252] Pattern bitmap, 1 represents that the MG is configured in the original MG period, and 0 represents that the MG is not configured in the original MG period.
[0253] Embodiment three, measurement reduction of the connected terminal (the terminal requests the first rule and the first configuration information from the network side device)
[0254] Step 0, the terminal reports support for the prediction-based connected measurement reduction function.
[0255] Step 1, the network side device sends a first parameter, and the first parameter includes at least one of the following:
[0256] A cell signal quality measurement value threshold, which is used to indicate whether the network side device allows the terminal to request to use the first rule for measurement relaxation. For example, if the RSRP measurement value measured by the terminal in the serving cell is greater than a fourth RSRP measurement value threshold, the network allows the terminal to request to use the first rule for measurement reduction.
[0257] A cell signal quality measurement change threshold for determining whether to use an AI model to predict the cell signal quality or instructing the network-side device whether to allow the terminal to request to use the first rule to predict the cell signal quality.
[0258] A first time length representing a time length corresponding to the cell signal quality measurement change. For example, if a decrease in the RSRP measurement value measured by the terminal in the serving cell within the first time length is less than or equal to the cell signal quality measurement change threshold, the network allows the terminal to request to use the first rule to predict the cell signal quality.
[0259] In particular, the above parameters can be indicated in OtherConfig.
[0260] Step 2: If the first parameter in step 1 meets a preset condition, the terminal sends a first request to the network-side device, and the first request is used to request the network-side device to send first configuration information so that the terminal predicts the cell signal quality based on the first configuration information. The first request includes at least one of the following:
[0261] Second indication information for indicating that the terminal meets the condition for measuring and relaxing using the first rule;
[0262] Third indication information for indicating the measurement gap required by the terminal to measure, and the third indication information can be implemented by a specific MG pattern. The third indication information includes at least one of the following:
[0263] Measurement gap MG configuration identification ID;
[0264] Pattern period; the pattern period can be an integer multiple of the original measurement gap MG period, or a specific length such as ms;
[0265] Pattern bitmap bitmap; for example, 1 indicates that the MG is configured in the original measurement gap MG period, and 0 indicates that the MG is not configured in the original measurement gap MG period.
