Please refer to Figure 2, which shows a flow chart of a signal measurement method according to 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 measurement of the first cell within the discontinuous reception DRX cycle.

The resource configuration information is resource configuration information generated by the network cell corresponding to the first cell when configuring network transmission for 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 location within the DRX, and the first measurement location is located in a time window within the multiple time windows.

Within a DRX, a terminal device may receive signals from multiple cells. Accordingly, the terminal device needs to perform network measurements on the multiple cells.

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

Step S203: The terminal equipment performs signal measurement on the second cell in the DRX at a second measurement location. The second measurement location does not overlap with the first measurement location, and the second measurement location is consistent with the first measurement location. The time interval between them is not greater than the time interval between 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 disposed in an idle position between the plurality of first measurement positions.

The way in which the terminal equipment performs signal measurement on the first cell or the second cell may be the same or different, and this is not specifically limited in this embodiment of the present application. For example, the terminal device may determine the measurement method 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 within a DRX cycle, the terminal equipment may need to perform signal measurements on multiple cells. Then, when performing cell measurements, the terminal device sequentially performs signal measurements on the multiple cells based on the measurement positions corresponding to each cell in the DRX cycle. That is, the terminal device performs step S202 and step S203 respectively to perform network measurement on the first cell and the second cell that need to be measured within the DRX cycle.

For the first cell and the second cell, the corresponding first measurement position or the second measurement position may be determined during the measurement, or may be determined before the measurement. In the embodiment of the present application, this is not specified. limited.

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 there is no need to start signal measurement from the current cell, thus avoiding the problem of long wait caused by missing the measurement position of the first cell, thus reducing the waiting time of the terminal equipment and improving the efficiency of the terminal equipment. of standby time.

For example, in this embodiment of the present application, within one DRX, signal measurement needs to be performed on multiple cells. Wherein, the first cell is a cell corresponding to the New Radio 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 explanation. Please refer to FIG. 3 , which shows a flow chart 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 can be measured within the 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 this embodiment of the present application, the repetition period of multiple time windows corresponding to the first cell can be understood as the sum of the duration of the time windows and the time intervals of 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, 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 plurality of 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.

The process of the terminal device determining the first cell from multiple cells can be implemented in the following ways.

In a first implementation manner, the terminal device randomly determines the 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 whose 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 location is to be determined from 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 among 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 multiple first cells are 2570MHz-2620MHz and 1880MHz-1920 MHz respectively. If the frequency bands are ordered from high to low, the cell corresponding to 2570MHz-2620MHz is determined as the first cell. One point that needs to be explained is that after the first measurement position of the cell corresponding to 2570MHz-2620MHz has been determined, the cell corresponding to 1880MHz-1920 MHz continues to be determined as the first cell for which the 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 the DRX from the multiple time windows corresponding to the multiple cells. Correspondingly, the first time window is determined. The cell corresponding to a time window is the first cell. Referring to Figure 4, Figure 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 within the 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, then cell 2 is determined as the first cell.

The process of determining the first time window by the terminal device from multiple time windows corresponding to multiple cells can be implemented in the following ways.

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

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

In a third implementation manner, the terminal device determines the first measurement position starting from the time window farthest from the paging starting position among multiple time windows in DRX. Referring to Figure 4, Figure 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 from the time window farthest from the paging starting position in DRX as the first time window.

One thing that needs to be explained is that in the case where the above time window 1 or time window 2 is the time window corresponding to the cell in which the first measurement position has been determined, the terminal device can continue to determine the first time window backward or forward, again The first measurement positions of other first cells in the DRX are determined until the first measurement position of the first cell in the DRX is determined.

Step S302: The terminal device determines the second measurement position based on the first measurement position.

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. , multiple second measurement positions are set in sequence after the last first measurement position. Referring to Figure 5, the first measurement position is the measurement position 1-3, and the second measurement position is the measurement position 4-6. After determining the measurement position 1-3, the terminal device sets the measurement position setting 4-6 at After measuring position 3.

In some embodiments, the terminal device sets multiple second measurement positions in idle positions between multiple first measurement positions respectively. Referring to Figure 6, the first measurement position is the measurement position 1-3, and the second measurement position is the measurement position 4-6. After determining the measurement position 1-3, the terminal device sets the measurement position setting 4-6 at Measure between positions 1-3. Referring to Figure 6, measurement position 4 is set between measurement position 1 and measurement position 2, measurement position 5 is set between measurement position 2 and measurement position 3, and measurement position 6 is set after measurement position 3.

In this embodiment of the present application, by arranging multiple second measurement locations between idle locations between multiple first measurement locations, the terminal device does not need to enter the sleep state after measuring the first cell at the first measurement location. , but maintains the working state, thereby reducing the number of times the terminal device wakes up, thereby reducing the energy consumption of the terminal device due to wake-up, thereby increasing the standby time of the terminal device. In addition, 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. This 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. of standby time.

One point that needs to be explained is that when 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 them between the first measurement positions. The second measurement positions are set sequentially after the last first measurement position.

In this embodiment of the present application, by first setting the first measurement position of the first cell where signal measurement needs to be performed in the time window, and then setting the second measurement position, there is no need to perform signal measurement based on the resident cell of the terminal device, thereby This avoids the problem of long waiting time caused by missing the measurement position of the first cell, 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 based on the current resident cell, thus avoiding the problem of long waiting time caused by missing the measurement position of the first cell, thus reducing the waiting time of the terminal equipment and improving the efficiency of the 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 , a flow chart of a signal measurement method according to an exemplary embodiment of the present application is shown. The method includes the following steps:

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

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 of 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 of 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 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, and continue to determine the first measurement position of a first cell from the time window corresponding to the remaining 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 has a portion that overlaps with the first time window, then the terminal device determines the time window corresponding to cell 1 The repetition period and the repetition period of the time window corresponding to cell 2. Continuing to refer to Figure 7, if the repetition period corresponding to cell 2 is greater than the repetition period corresponding to cell 1, then the terminal device configures the time window of cell 2 that overlaps 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 no longer be configured in the subsequent configuration process.

In the subsequent configuration process, no longer configuring the cell means that in the process of determining the first time window, the time window corresponding to the cell in which the first measurement position is not configured is determined. Alternatively, in the process of determining whether there is an overlapping time window in the first time window, it is determined from a time window corresponding to a cell in which the first measurement position is not configured.

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

For example, continuing to refer to Figure 8, after cell 1 is configured with the first measurement position, the first time window is determined backward from cell 1. This first time window is the time window of cell 2 and does not exist with cell 2. The first time window overlaps with the time window, then the first time window is determined as the first measurement position of 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 there is no need to start signal measurement from the current cell, thus avoiding the problem of long wait caused by missing the measurement position of the first cell, thus reducing the waiting time of the terminal equipment and improving the efficiency of the terminal equipment. of 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. See Figure 9. The process includes :

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

902. Determine whether there is a time window of other first cells that overlaps with the first time window;

903. If there is no other time window of the first cell that overlaps with the first time window, allocate the current measurement position to the first cell;

904. If there is another first cell whose time window 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 the first cell is all configured with measurement positions;

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

907. If there is no first cell that has not been assigned a measurement position, allocate the measurement position of the second cell to the interval between the first measurement positions;

908. The second cells that are not completely arranged within the interval are assigned to the first measurement position at the back of the measurement position and then proceed in sequence;

909. Perform signal measurement based on the measurement location.

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 there is no need to start signal measurement from the current cell, thus avoiding the problem of long wait caused by missing the measurement position of the first cell, thus reducing the waiting time of the terminal equipment and improving the efficiency of the terminal equipment. of standby time.

In some embodiments, the terminal device determines the first measurement position according to different methods to obtain different signal measurement strategies. By comparing the power consumption parameters of multiple different signal measurement strategies, the signal measurement strategy with the smallest power consumption parameters is selected for signal measurement. Measurement.

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

For example, see Figures 10 and 11. Figure 10 is a signal measurement strategy corresponding to the way in which the first measurement position is determined starting from the time window closest to the paging starting position in DRX. Figure 11 is a signal measurement strategy in DRX where all In the above-mentioned DRX, the signal measurement strategy corresponding to the method of determining the first measurement position starting from the time window farthest from the paging starting position. Among them, the paging starting position is used to indicate the starting position of DRX. Referring to Figure 12, a flow chart of a signal measurement method according to an exemplary embodiment of the present application is shown.

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 the power consumption parameter of the first measurement position determined from the time window closest to the paging starting position. The second power consumption parameter is The power consumption parameter is the power consumption parameter of the first measurement position determined from the time window farthest from the paging starting position.

When making signal measurements, the sum of signal measurement power consumption is equal. The difference in power consumption is mainly reflected in the number of wake-ups of the terminal device and the working time of the terminal device caused by the preparation stage of signal measurement. Therefore, you only need to compare the power consumption corresponding to the working time of the terminal device outside of the signal measurement operation and the sum of the wake-up power consumption. Therefore, based on each signal measurement strategy, the terminal device determines the number of wake-ups of the terminal device, 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 1.

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 consumed by wake-up, and p2 is the power consumption of the terminal device working per unit time.

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

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

Wherein, when the first power consumption parameter is less than the second power consumption parameter, the terminal device performs signal measurement at the first measurement position and the second measurement position determined from front to back in the discontinuous reception cycle. In the case where the first power consumption parameter is greater than the second power consumption parameter, the terminal device performs signal measurement at the first measurement position and the second measurement position determined from back to front in the discontinuous reception period.

It should be noted that the terminal device can also determine the first measurement position through other methods, and then determine the signal measurement strategy, for example, randomly determine the first measurement position, or determine the first measurement position according to the frequency band corresponding to each cell, etc. In the embodiment of the present application, there is no specific limitation on this. The terminal device can determine the signal measurement strategy with the smallest power consumption from multiple signal measurement strategies through the above steps S1201-S1202.

In this embodiment of the present application, the terminal device determines the first time window from different locations to obtain different signal measurement strategies. By determining the power consumption parameters corresponding to each signal measurement strategy, the terminal device determines the signal with the smallest power consumption parameters. Measurement strategy: perform signal measurement on multiple cells based on the first measurement position and the second measurement position corresponding to the signal measurement strategy, thereby further reducing the power consumption of signal measurement and increasing the standby time of the terminal device.

It should be noted that the above-mentioned steps S301-S302, steps S701-S702 and steps S1201-S1202 used to determine the cell measurement location can be executed by the terminal device or the network device.
