Referring to FIG. 1 , the implementation environment includes: a terminal device 10 and a network device 20 . The number of terminal devices 10 and network devices 20 may be one or more. In the embodiment of the present application, one terminal device 10 and one network device 20 are taken as an example for illustration. The terminal device 10 and the network device 20 are connected through a network.

In the embodiment of the present application, no specific limitation is made on this.

Please refer to FIG. 2 , which shows a flowchart of a signal measurement method shown in an exemplary embodiment of the present application. The method includes the following steps:

Step S201: The terminal device receives resource configuration information, where the resource configuration information is used to indicate multiple time windows for performing measurements on the first cell in a discontinuous reception DRX cycle.

The resource configuration information is resource configuration information generated by the network cell corresponding to the first cell when performing network transmission configuration on the first cell. In this step, the terminal device receives the resource configuration information sent by the network device corresponding to the first cell.

Step S202: Based on the resource configuration information, the terminal device performs signal measurement on the first cell at a first measurement position in the DRX, where the first measurement position is located in a time window of the plurality of time windows.

In one DRX, a terminal device may receive signals from multiple cells. Correspondingly, the terminal device needs to perform network measurements on the multiple cells.

In this step, the terminal device determines a first measurement position corresponding to the first cell in DRX based on the resource configuration information, and performs signal measurement on the first cell based on the first measurement position. In some embodiments, the terminal device may also determine the measurement position of each cell in DRX based on the resource configuration information before this step. In this step, the measurement position of each cell determined in advance is obtained, and based on the measurement position The first cell performs signal measurement.

Step S203: The terminal device performs signal measurement on the second cell at a second measurement position in the DRX, the second measurement position does not overlap with the first measurement position, and the second measurement position is identical to the first measurement position The time interval between them is not greater than the time interval of adjacent time windows.

In this step, the terminal device measures the second cell based on the second measurement position corresponding to the second cell. Wherein, the second measurement position is a measurement position determined based on the first measurement position. Exemplarily, the second measurement position is set in an idle position among the plurality of first measurement positions.

For example, the terminal device may determine the measurement manner of the first cell or the second cell based on the network type of the first cell or the second cell.

It should be noted that in one DRX cycle, the terminal equipment may need to perform signal measurement on multiple cells. Then, when performing cell measurement, the terminal device performs signal measurement on the multiple cells sequentially based on the measurement positions corresponding to each cell in the DRX cycle. That is, the terminal device respectively performs step S202 and step S203 to perform network measurement on the first cell and the second cell that need to be measured in the DRX cycle.

For the first cell and the second cell, the corresponding first measurement position or the second measurement position can be determined during the measurement, or can be determined before the measurement. In this embodiment of the application, no specific description is made on this limited.

To sum up, in the embodiment of the present application, through multiple time windows for measurement of the first cell in the DRX cycle, the signal measurement of the first cell that needs to be measured in the time window is performed at the first measurement position. Signal measurement is performed at the second measurement position, so that there is no need to start signal measurement from the cell where the current camp is located, thereby avoiding the problem of waiting for a long time caused by missing the measurement position of the first cell, thereby reducing the waiting time of terminal equipment , improving the standby time of the terminal equipment.

Optionally, the method also includes:

The first measurement positions of the plurality of first cells are determined sequentially according to the time window corresponding to the largest repetition period.

Optionally, when there are multiple first cells, determining the first measurement position within multiple time windows according to resource configuration information includes:

A first measurement location is determined in a first time window of each first cell.

Optionally, according to the time window corresponding to the largest repetition period in turn, the manner of determining the first measurement positions of the plurality of first cells includes at least one of the following manners:

In DRX, determine the first measurement position from the time window closest to the paging start position;

In DRX, the first measurement position is determined from the time window farthest from the paging start position;

Wherein, the paging start position is used to indicate the start position of DRX.

Optionally, in the case where the first measurement position is determined in multiple ways, the method further includes:

Determine the first power consumption parameter and the second power consumption parameter, the first power consumption parameter is the power consumption parameter of the first measurement position determined from the time window closest to the paging starting position, and the second power consumption parameter is the power consumption parameter from the distance paging start position Determine the power consumption parameter of the first measurement position in the time window farthest from the call start position;

Based on the first power consumption parameter and the second power consumption parameter, a cell measurement mode with a small power consumption parameter is determined to perform cell measurement.

Optionally, the second measurement position is set in an idle position between the plurality of first measurement positions.

Optionally, the first cell is a cell corresponding to the New Radio Interface NR system, and the second cell is a cell corresponding to the Long Term Evolution LTE, Universal Mobile Telecommunications System UMTS or Global System for Mobile Communications GSM system.

Exemplarily, in the embodiment of the present application, signal measurement needs to be performed on multiple cells within one DRX. Wherein, the first cell is a cell corresponding to the New Radio Interface NR system, and the second cell is a cell corresponding to the Long Term Evolution LTE, Universal Mobile Telecommunications System UMTS or Global System for Mobile Communications GSM system. In the embodiment of the present application, the determination of the first measurement position and the second measurement position based on the resource configuration information is taken as an example for description. Please refer to FIG. 3 , which shows a flowchart of a signal measurement method according to an exemplary embodiment of the present application. The method includes the following steps:

Step S301: The terminal device determines the first measurement position within the multiple time windows according to the resource configuration information.

Wherein, at least one first cell may be measured in DRX. Wherein, for each first cell, the first cell corresponds to multiple time windows, and the multiple time windows periodically appear in the DRX based on the repetition period.

In the embodiment of the present application, the repetition period of the multiple time windows corresponding to the first cell may be understood as the sum of the duration of the time window and the time interval between adjacent time windows among the multiple time windows corresponding to the first cell. For example, if the time window is 20 milliseconds and the time interval between adjacent time windows is 30 milliseconds, then the repetition period is 50 milliseconds.

In some embodiments, the terminal device first determines the first cell, and then determines the first time window corresponding to the first cell. Correspondingly, the terminal device determines the first cell whose measurement position is currently to be determined from the multiple first cells, determines multiple time windows corresponding to the first cell, and determines the first cell in the DRX from the multiple time windows. time window.

Wherein, the process for the terminal device to determine the first cell from multiple cells may be implemented in the following ways.

In a first implementation manner, the terminal device randomly determines a first cell from multiple first cells. It should be noted that if the randomly determined first cell is a cell for which the first measurement position has not been determined, the terminal device determines the first cell as the first cell for which the measurement position is to be determined. If the randomly determined first cell is a cell for which the first measurement position has been determined, continue to randomly determine a first cell from other first cells until the determined first cell is a cell for which the first measurement position has not been determined.

In a second implementation manner, the terminal device determines the first cell whose measurement position is to be determined from the multiple first cells based on the frequency band corresponding to each first cell. Correspondingly, based on the frequency band where the first cell is located, the terminal device sequentially determines the first cell whose measurement position is to be determined from the plurality of first cells in the order of frequency bands from high to low or from low to high. For example, the cell frequency bands corresponding to the multiple first cells are 2570MHz-2620MHz and 1880MHz-1920MHz respectively, and the cell corresponding to 2570MHz-2620MHz is determined as the first cell in the order of frequency bands from high to low. It should be noted that after the first measurement position of the cell corresponding to 2570MHz-2620MHz is determined, continue to determine the cell corresponding to 1880MHz-1920MHz as the first cell whose measurement position is to be determined.

In some embodiments, the terminal device determines multiple time windows corresponding to each of the multiple cells, and determines the first time window in DRX from the multiple time windows corresponding to the multiple cells, and correspondingly, the first time window The cell corresponding to one time window is the first cell. Referring to Fig. 4, Fig. 4 shows multiple time windows corresponding to cell 1 and cell 2 in DRX. For cell 1 and cell 2, the measurement window 1 of cell 1 is the first time window in DRX, so cell 1 is determined as the first cell. When the first measurement position corresponding to cell 1 has been determined, in addition to the application window corresponding to cell 1 in DRX, the time window of cell 2 is the first time window, and cell 2 is determined as the first cell.

Wherein, the process for the terminal device to determine the first time window from the multiple time windows corresponding to the multiple cells can be realized in the following ways.

In the first implementation manner, the terminal device randomly determines the first time window from the multiple time windows corresponding to the multiple cells.

In the second implementation manner, the terminal device determines the first measurement position from the time window closest to the paging starting position among multiple time windows in DRX. Please continue to refer to FIG. 4 , through the method provided by this implementation, the terminal device determines the time window 1 that appears first from the time window closest to the paging start position in DRX as the first time window.

In a third implementation manner, the terminal device determines the first measurement position from the time window farthest from the paging start position among multiple time windows in DRX. Referring to Fig. 4, Fig. 4 shows multiple time windows corresponding to cell 1 and cell 2 in DRX. Through the method provided by this implementation, the terminal device determines the first time window 2 that appears first from the time window farthest from the paging start position in DRX as the first time window.

It should be noted that, in the case that the above time window 1 or time window 2 is the time window corresponding to the cell whose first measurement position has been determined, the terminal device can continue to determine the first time window backward or forward, and once Determine the first measurement positions of other first cells in the DRX until the first measurement positions of the first cells in the DRX are determined.

Step S302: The terminal device determines the second measurement location according to the first measurement location.

In some embodiments, the terminal device configures the second measurement positions of multiple second cells after the last first measurement position, that is, the terminal device determines the last measurement position in DRX from the multiple first measurement positions , setting the multiple second measurement positions sequentially after the last first measurement position. Referring to FIG. 5 , where the first measurement positions are measurement positions 1 to 3, and the second measurement positions are measurement positions 4 to 6, then after determining the measurement positions 1 to 3, the terminal device sets the measurement position settings 4 to 6 at After measuring position 3.

In some embodiments, the terminal device sets the multiple second measurement positions in idle positions between the multiple first measurement positions, respectively. Referring to FIG. 6 , where the first measurement positions are measurement positions 1 to 3, and the second measurement positions are measurement positions 4 to 6, then after determining the measurement positions 1 to 3, the terminal device sets the measurement position settings 4 to 6 at Between measuring positions 1 and 3. Referring to FIG. 6 , the measurement position 4 is set between the measurement position 1 and the measurement position 2 , the measurement position 5 is set between the measurement position 2 and the measurement position 3 , and the measurement position 6 is set after the measurement position 3 .

In the embodiment of the present application, by setting multiple second measurement positions between idle positions among multiple first measurement positions, the terminal device does not need to enter the dormant state after measuring the first cell at the first measurement position , but keeps the working state, thereby reducing the number of wake-ups of the terminal device, thereby reducing the energy consumption of the terminal device due to wake-up, and thus increasing the standby time of the terminal device. Moreover, when the terminal device performs signal measurement on the first cell based on the first measurement position, it can prepare for the measurement of other cells, which reduces the wake-up time of the terminal device, further reduces the energy consumption of the terminal device, and improves the efficiency of the terminal device. standby time.

It should be noted that if the number of second cells is greater than the number of intervals between two adjacent first measurement positions among the plurality of first measurement positions, it will not be possible to set the second cell between the first measurement positions. The second measurement position of is sequentially set after the last first measurement position.

In the embodiment of the present application, by first setting the first measurement position of the first cell that needs to perform signal measurement in the time window, and then setting the second measurement position, there is no need to perform signal measurement according to the cell where the terminal device resides, thereby The problem of long waiting time caused by missing the measurement position of the first cell is avoided, thereby reducing the waiting time of the terminal equipment and increasing the standby time of the terminal equipment.

In the embodiment of the present application, through multiple time windows for measuring the first cell in the DRX cycle, the signal measurement of the first cell that needs to be measured in the time window is performed at the first measurement position, and the signal measurement is performed at the second measurement position. Signal measurement, so that there is no need to perform signal measurement according to the cell currently residing, thereby avoiding the problem of waiting for a long time caused by missing the measurement position of the first cell, thereby reducing the waiting time of terminal equipment and improving the reliability of terminal equipment. Standby time.

It should be noted that when multiple first cells need to be measured in DRX, when the first time window corresponding to the first cell is determined through the above step S301, the time windows of multiple first cells may overlap , in this case, the terminal device determines the first measurement position according to the repetition period of the time window. Referring to FIG. 7 , it shows a flowchart of a signal measurement method shown in an exemplary embodiment of the present application. The method includes the following steps:

Step S701: The terminal device determines, according to the resource configuration information, the repetition periods of the time windows respectively corresponding to the plurality of first cells.

In some embodiments, for any first cell, the terminal device determines the time window corresponding to the first cell, and determines the time difference between the starting positions of the time windows in each time window as the time window corresponding to the first cell. The recurrence period for the time window.

In some embodiments, for any first cell, the repetition period of the time window corresponding to the first cell is determined when the terminal device in the first cell configures the first cell. Correspondingly, the terminal device determines the repetition period of the time window corresponding to the first cell from the resource configuration information of the first cell.

Step S702: The terminal device sequentially determines the first measurement positions of the plurality of first cells according to the time window corresponding to the largest repetition period.

In this step, the terminal device compares the repetition periods corresponding to the overlapping time windows, and determines the time window with the largest repetition period as the first measurement position of the first cell. Then continue to execute step S301, continue to determine the first measurement position of one first cell from the remaining time window corresponding to the first cell.

For example, as shown in Figure 8, the first time window is the time window of cell 1, and the time window of cell 2 overlaps with the first time window, then the terminal device determines the time window corresponding to cell 1 The repetition period of and the repetition period of the time window corresponding to cell 2. Continuing to refer to FIG. 8, if the repetition period corresponding to cell 2 is greater than the repetition period corresponding to cell 1, the terminal device configures the time window of cell 2 overlapping with the first time window as the first measurement position.

It should be noted that after any cell is configured with the first measurement position, the cell will not be configured in the subsequent configuration process.

In the subsequent configuration process, no longer configure the cell means: in the process of determining the first time window, it is determined in the time window corresponding to the cell from which the first measurement position is not configured. Or, in the process of determining whether there is a coincident time window in the first time window, it is determined from the time window corresponding to the cell that is not configured with the first measurement position.

Another point that needs to be explained is that, in a case where the first time window of the first cell does not overlap with time windows corresponding to other first cells, the terminal device configures the first time window as the first measurement position.

For example, continue to refer to FIG. 8, after the cell 1 is configured with the first measurement position, the first time window is determined backward from the cell 1, the first time window is the time window of the cell 2, and there is no If the time window overlaps with the first time window of the cell 2, the first time window is determined as the first measurement position of the cell 2.

In the embodiment of the present application, through multiple time windows for measuring the first cell in the DRX cycle, the signal measurement of the first cell that needs to be measured in the time window is performed at the first measurement position, and the signal measurement is performed at the second measurement position. Signal measurement, so that there is no need to start signal measurement from the cell where the current resides, thereby avoiding the problem of waiting for a long time caused by missing the measurement position of the first cell, thereby reducing the waiting time of terminal equipment and improving terminal equipment. standby time.

Based on the above embodiment, when the time windows of multiple first cells overlap, the terminal device determines the corresponding first measurement position based on the repetition period of the time window of each first cell. Referring to FIG. 9 , the process includes :

901. Determine the first time window of the first cell;

902. Determine whether there are time windows of other first cells overlapping with the first time window;

903. If there is no other time window of the first cell overlapping the first time window, assign the current measurement position to the first cell;

904. If the time window of other first cells overlaps with the first time window, select the first cell with a larger repetition period and assign it to the current measurement position;

905. Determine whether all the first cells are configured with measurement locations;

906. If there is a first cell that has not been assigned a measurement location, continue to execute step 901;

907. If there is no first cell to which no measurement position is allocated, allocate the measurement position of the second cell to the interval between the first measurement positions;

908. The second cells that cannot be arranged in the interval are allocated to the first measurement position that is the lastest in the measurement position, and then performed sequentially;

909. Perform signal measurement based on the measurement location.

In some embodiments, the terminal device determines the first measurement position in different ways, thereby obtaining different signal measurement strategies, and by comparing the power consumption parameters of multiple different signal measurement strategies, selects the signal measurement strategy with the smallest power consumption parameter for signal measurement. Measurement.

Correspondingly, the terminal device respectively determines different first cells, and repeats the above steps S301 to S302 through different first cells to obtain multiple different first measurement positions and multiple second measurement positions.

For example, referring to FIG. 10 and FIG. 11, FIG. 10 shows the signal measurement strategy corresponding to the method of determining the first measurement position starting from the time window closest to the paging start position in DRX, and FIG. 11 shows the signal measurement strategy in DRX. In the DRX described above, the signal measurement strategy corresponds to the method of determining the first measurement position from the time window farthest from the paging start position. Wherein, the paging start position is used to indicate the start position of DRX. Referring to FIG. 12 , it shows a flowchart of a signal measurement method shown in an exemplary embodiment of the present application. The method includes the following steps:

Step S1201: The terminal device determines a first power consumption parameter and a second power consumption parameter, the first power consumption parameter is a power consumption parameter determined at a first measurement location from the time window closest to the paging starting location, and the second power consumption parameter The power consumption parameter is the power consumption parameter of the first measurement position determined from the time window farthest from the paging start position.

When performing signal measurements, the sum of the signal measurement power consumption is equal. The difference in power consumption is mainly reflected in the number of wake-ups of the terminal equipment and the working hours of the terminal equipment caused by the preparation stage of signal measurement. Therefore, it is only necessary to compare the sum of the power consumption and the wake-up power consumption corresponding to the working time of the terminal equipment other than the signal measurement operation. Therefore, based on each signal measurement strategy, the terminal device determines the number of wake-up times of the terminal device and the working time of the terminal device outside the measurement operation, and determines the power consumption of the signal measurement strategy based on the following formula one.

Formula 1: P=T1+a×(p1/p2)

P is the power consumption coefficient; T1 is the working time of the terminal device outside the measurement operation; a is the number of wake-ups; p1 is the power consumption of the wake-up, and p2 is the power consumption of the terminal device per unit time.

It should be noted that, after each signal measurement strategy is determined, the terminal device may determine the power consumption parameter of the signal measurement strategy. The terminal device may also separately determine the power consumption parameter of each signal measurement strategy after determining multiple signal measurement strategies. In the embodiment of the present application, no specific limitation is made on this.

Step S1202: Based on the first power consumption parameter and the second power consumption parameter, the terminal device determines a cell measurement mode with a small power consumption parameter to perform cell measurement.
