Referring to fig. 1, a schematic diagram of an implementation environment related to a signal measurement method according to an exemplary embodiment of the present application is shown. Referring to fig. 1, the implementation environment includes: a terminal device 10 and a network device 20. In this embodiment, one terminal device 10 and one network device 20 are taken as an example for description. The terminal device 10 and the network device 20 are connected via a network.
In the embodiment of the present application, the cell to be measured is the 5th generation Mobile communication technology (5G), which is also called a cell corresponding to a New Radio (NR) System, or the cell to be measured includes a cell corresponding to a 5G System and a cell corresponding to at least one of an LTE System, a Universal Mobile Telecommunications System (UMTS) System, or a Global System for Mobile Communications (GSM) System, which is not specifically limited in the embodiment of the present application.
The network device 20 is any network device 20 with a wireless transceiving function. For example, the network device 20 is a base station, an evolved Node B (eNB), an Access Point (AP) in a Wireless Fidelity (WIFI) system of a next Generation Node B (gNB), a Wireless relay Node, a Wireless backhaul Node, a Transmission Point (TP), a Transmission and Reception Point (TRP), or the like.

The terminal device 10 may be a mobile phone, a tablet computer, a computer with a wireless communication function, or a wearable device. In the embodiments of the present application, this is not particularly limited.
Referring to fig. 2, a flow chart of a signal measurement method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S201: the terminal device receives resource configuration information indicating a plurality of time windows for measurements to be made for a first cell within a discontinuous reception, DRX, cycle.
The resource configuration information is resource configuration information generated when a network cell corresponding to the first cell performs network transmission configuration on the first cell. In this step, the terminal device receives resource configuration information sent by the network device corresponding to the first cell.
Step S202: and the terminal equipment performs signal measurement on the first cell at a first measurement position within the DRX based on the resource configuration information, wherein the first measurement position is located in one time window in the plurality of time windows.
Within one DRX, a terminal device may receive signals of multiple cells. Accordingly, the terminal device needs to perform network measurements on the plurality of cells.
In this step, the terminal device determines a first measurement position corresponding to the first cell within 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 may further determine a measurement position of each cell in DRX based on the resource configuration information before this step, and in this step, obtain the measurement position of each cell determined in advance, and perform signal measurement on the first cell based on the measurement position.
Step S203: and the terminal equipment performs signal measurement on the second cell at a second measurement position within the DRX, wherein the second measurement position is not overlapped with the first measurement position, and the time interval between the second measurement position and the first measurement position is not more than that of an adjacent time window.
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. Illustratively, the second measurement location is disposed within an idle location between the plurality of first measurement locations.
The signal measurement mode of the terminal device for the first cell or the second cell may be the same or different, and this is not particularly limited in this embodiment of the application. For example, the terminal device may determine the measurement mode 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, during one DRX cycle, the terminal device may need to perform signal measurement on multiple cells. When the terminal device performs cell measurement, the terminal device sequentially performs signal measurement on the multiple cells based on the measurement position corresponding to each cell in the DRX cycle. Namely, the terminal device performs step S202 and step S203 to perform network measurement on the first cell and the second cell to be measured in the DRX cycle, respectively.
For the first cell and the second cell, the corresponding first measurement position or second measurement position may be determined during measurement or may be determined before measurement, which is not specifically limited in the embodiment of the present application.
In the embodiment of the application, through a plurality of time windows for measuring the first cell in the DRX cycle, the first cell requiring signal measurement in the time window is measured at the first measurement position, and the second cell is measured at the second measurement position, so that signal measurement does not need to be performed from the currently camped cell, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
For example, in the embodiment of the present application, signal measurements need to be performed on multiple cells within one DRX. The first cell is a cell corresponding to a new air interface NR system, and the second cell is a cell corresponding to a long term evolution LTE, a universal mobile telecommunications system UMTS, or a global system for mobile communications GSM system. In the embodiment of the present application, an example of determining the first measurement location and the second measurement location based on the resource configuration information is described. Referring to fig. 3, a flow chart of a signal measurement method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S301: and the terminal equipment determines the first measurement position in the plurality of time windows according to the resource configuration information.
Wherein the at least one first cell may be measured within DRX. Wherein for each first cell, the first cell corresponds to a plurality of time windows that occur periodically within DRX based on a repetition period.
In this 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 a time window and the time interval of an adjacent time window in the multiple time windows corresponding to the first cell. For example, if the time window is 20 ms, and the time interval of the adjacent time window is 30 ms, the repetition period is 50 ms.
In some embodiments, the terminal device determines the first cell first, and then determines a first time window corresponding to the first cell. Correspondingly, the terminal equipment determines a first cell of which the measurement position is to be determined currently from a plurality of first cells, determines a plurality of time windows corresponding to the first cell, and determines a first time window in the DRX from the plurality of time windows.
The process of determining the first cell from the plurality of cells by the terminal device may be implemented in the following manners.
In a first implementation, a terminal device randomly determines a first cell from a plurality of first cells. It should be noted that, if the randomly determined first cell is a cell for which the first measurement position is not 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 the cell with the first measurement position determined, randomly determining a first cell from other first cells continuously until the determined first cell is the cell without the first measurement position determined.
In a second implementation manner, the terminal device determines, from the plurality of first cells, a first cell whose measurement position is to be determined, based on the frequency band corresponding to each first cell. Correspondingly, the terminal device determines the first cells of the measurement positions to be determined from the plurality of first cells in sequence according to the sequence of the frequency bands from high to low or from low to high based on the frequency band where the first cells are located. For example, the frequency bands of the cells corresponding to the plurality of first cells are 2570MHz-2620MHz and 1880MHz-1920 MHz, respectively, and if the frequency bands are in the order from high to low, the cell corresponding to the 2570MHz-2620MHz is determined as the first cell. It should be noted that, after the first measurement position of the cell corresponding to 2570MHz-2620MHz is determined, the cell corresponding to 1880MHz-1920 MHz is continuously determined as the first cell of which the measurement position is to be determined.
In some embodiments, the terminal device determines a plurality of time windows corresponding to each of a plurality of cells, and determines a first time window within DRX from the plurality of time windows corresponding to the plurality of cells, and accordingly, a cell corresponding to the first time window is the first cell. Referring to fig. 4, a plurality of time windows corresponding to cell 1 and cell 2 in DRX are shown in fig. 4. For cell 1 and cell 2, measurement window 1 for cell 1 is the first time window within DRX, and thus cell 1 is determined to be the first cell. When the first measurement position corresponding to the cell 1 is determined, the cell 2 is determined as the first cell in the DRX, except for the application window corresponding to the cell 1, and the time window of the cell 2 is the first time window.
The process of determining the first time window from the plurality of time windows corresponding to the plurality of cells by the terminal device may be implemented in the following manners.
In a first implementation manner, a terminal device randomly determines a first time window from a plurality of time windows corresponding to a plurality of cells.
In a second implementation manner, the terminal device determines the first measurement position from the time window closest to the paging starting position in a plurality of time windows in the DRX. With continued reference to fig. 4, with the method provided by this implementation manner, the terminal device determines, in DRX, a time window 1 that appears first from a time window closest to the paging starting position as a first time window.
In a third implementation manner, the terminal device determines the first measurement position from the time window farthest from the paging starting position in a plurality of time windows in the DRX. Referring to fig. 4, a plurality of time windows corresponding to cell 1 and cell 2 in DRX are shown in fig. 4. By the method provided by the implementation mode, the terminal equipment determines the time window 2 which starts to appear first from the time window farthest from the paging starting position in the DRX as the first time window.
It should be noted that, in the case that the time window 1 or the time window 2 is a time window corresponding to a cell for which the first measurement position has been determined, the terminal device may continue to determine the first time window backward or forward, and determine the first measurement positions of other first cells in the DRX again until the first measurement position of the first cell in the DRX is determined.
Step S302: and the terminal equipment determines the second measuring position according to the first measuring position.
In some embodiments, the terminal device configures the second measurement positions of the plurality of second cells after the last first measurement position, that is, the terminal device determines the last measurement position in DRX from the plurality of first measurement positions, and sequentially sets the plurality of second measurement positions after the last first measurement position. Referring to fig. 5, where the first measurement position is measurement position 1-3 and the second measurement position is measurement position 4-6, the terminal device sets measurement position 4-6 after measurement position 3 after determining measurement position 1-3.
In some embodiments, the terminal device sets a plurality of second measurement positions in idle positions between the plurality of first measurement positions, respectively. Referring to fig. 6, wherein the first measurement position is measurement position 1-3, and the second measurement position is measurement position 4-6, the terminal device sets measurement position 4-6 between measurement positions 1-3 after determining measurement position 1-3. Referring to fig. 6, the measurement position 4 is disposed between the measurement position 1 and the measurement position 2, the measurement position 5 is disposed between the measurement position 2 and the measurement position 3, and the measurement position 6 is disposed behind the measurement position 3.
In the embodiment of the application, the plurality of second measuring positions are arranged between the idle positions among the plurality of first measuring positions, so that the terminal equipment does not need to enter a dormant state but keeps a working state after measuring the first cell at the first measuring position, the awakening times of the terminal equipment are reduced, the energy consumption of the terminal equipment due to awakening is reduced, and the standby duration of the terminal equipment is prolonged. And when the terminal equipment measures the signal of the first cell based on the first measurement position, the measurement of other cells can be prepared, so that the awakening time of the terminal equipment is shortened, the energy consumption of the terminal equipment is further reduced, and the standby time of the terminal equipment is prolonged.
It should be noted that, in the case where the number of second cells is larger than the number of intervals between two adjacent first measurement positions among the plurality of first measurement positions, the second measurement position that cannot be set between the first measurement positions is set in order after the last first measurement position.
In the embodiment of the application, the first measurement position of the first cell, which needs to perform signal measurement in the time window, is set first, and then the second measurement position is set, so that signal measurement does not need to be performed according to the resident cell of the terminal device, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
In the embodiment of the application, through a plurality of time windows for measuring the first cell in the DRX cycle, the first cell requiring signal measurement in the time window is measured at the first measurement position, and the second cell is measured at the second measurement position, so that signal measurement does not need to be performed according to the currently camped cell, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
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 in step S301, the time windows of the multiple first cells may overlap, and in this case, the terminal device determines the first measurement position according to the repetition period of the time windows. Referring to fig. 7, a flow chart of a signal measurement method shown in an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S701: and the terminal equipment determines the repetition periods of the time windows respectively corresponding to the plurality of first cells according to the resource configuration information.
In some embodiments, for any first cell, the terminal device determines a time window corresponding to the first cell, and determines a time difference between starting positions of the time windows in each time window as a repetition period of the time window corresponding to the first cell.
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: and the terminal equipment determines the first measurement positions of the plurality of first cells in sequence according to the time windows corresponding to the maximum repetition period.
In this step, the terminal device compares repetition periods corresponding to the overlapped time windows, and determines the time window with the largest repetition period as the first measurement position of the first cell. Then, step S301 is executed to continue to determine the first measurement position of the laughing one first cell from the time windows corresponding to the remaining first cells.
For example, as shown in fig. 8, the first time window is the time window of cell 1, and there is a portion overlapping with the first time window in the time window of cell 2, the terminal device determines the repetition period of the time window corresponding to cell 1 and the repetition period of the time window corresponding to cell 2. With continued reference to fig. 7, 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 that overlaps with the first time window as the first measurement position.
It should be noted that after any cell is configured with the first measurement location, the cell is not configured any more in the following configuration process.
In the following configuration process, no longer configuring the cell means: in the process of determining the first time window, the first measurement position is determined from the time window corresponding to the cell which is not configured with the first measurement position. Or, in the process of determining whether the first time window has a coincident time window, determining from the time window corresponding to the cell which is not configured with the first measurement position.
It should be noted 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, with continued reference to fig. 8, after cell 1 is configured with the first measurement location, a first time window is determined from cell 1 backwards, the first time window being the time window of cell 2, and if there is no time window overlapping the first time window of cell 2, the first time window is determined as the first measurement location of cell 2.
In the embodiment of the application, through a plurality of time windows for measuring the first cell in the DRX cycle, the first cell requiring signal measurement in the time window is measured at the first measurement position, and the second cell is measured at the second measurement position, so that signal measurement does not need to be performed from the currently camped cell, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
Based on the foregoing embodiment, in the case that the time windows of the plurality of 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 fig. 9, and the process includes:
901. determining a first time window of a first cell;
902. judging whether the time windows of other first cells are overlapped with the first time window or not;
903. if the time windows of other first cells are not overlapped with the first time window, distributing the current measurement position for the first cell;
904. if the time windows of other first cells are overlapped with the first time window, selecting the first cell with a larger repetition period to be distributed at the current measurement position;
905. judging whether the first cells are all configured with measurement positions;
906. if there is a first cell to which a measurement location is not allocated, continue to execute step 901;
907. if the first cell which is not allocated with the measuring position does not exist, the measuring position of the second cell is allocated to the interval between the first measuring positions;
908. allocating the second cells which are not arranged in the interval to the first measuring position at the most back of the measuring position and then sequentially carrying out the measurement;
909. signal measurements are made based on the measurement locations.
In the embodiment of the application, through a plurality of time windows for measuring the first cell in the DRX cycle, the first cell requiring signal measurement in the time window is measured at the first measurement position, and the second cell is measured at the second measurement position, so that signal measurement does not need to be performed from the currently camped cell, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
In some embodiments, the terminal device determines the first measurement position according to different modes, so as to obtain different signal measurement strategies, and selects a signal measurement strategy with the minimum power consumption parameter for signal measurement by comparing power consumption parameters of a plurality of different signal measurement strategies.
Accordingly, the terminal device determines different first cells respectively, and repeats the above steps S301 to S302 through the different first cells to obtain different first measurement positions and second measurement positions.
For example, referring to fig. 10 and 11, fig. 10 is a signal measurement strategy corresponding to a manner of determining a first measurement position from a time window closest to a paging start position in DRX, and fig. 11 is a signal measurement strategy corresponding to a manner of determining a first measurement position from a time window farthest from the paging start position in DRX. Wherein, the paging starting position is used for representing the starting position of DRX. Referring to fig. 12, a flow chart of a signal measurement method shown in an exemplary embodiment of the present application is shown.
The method comprises the following steps:
step S1201: the terminal equipment determines a first power consumption parameter and a second power consumption parameter, wherein the first power consumption parameter is the power consumption parameter for determining the first measuring position from the time window nearest to the paging starting position, and the second power consumption parameter is the power consumption parameter for determining the first measuring position from the time window farthest to the paging starting position.
When signal measurements are made, the sum of the signal measurement power consumptions is equal. The power consumption difference is mainly reflected in the wake-up times of the terminal equipment and the working time of the terminal equipment caused by the preparation phase of signal measurement. So that it is only necessary to compare the sum of the power consumption corresponding to the operating time of the terminal device other than the signal measurement operation and the wake-up power consumption. Therefore, the terminal device determines the awakening times of the terminal device and the working time of the terminal device outside the measurement operation based on each signal measurement strategy, and determines the power consumption of the signal measurement strategy based on the following formula I.
The formula I is as follows: P-T1 + a X (P1/P2)
P is a power consumption coefficient; t1 is the working time of the terminal equipment outside the measuring operation; a is the number of awakenings; p1 is power consumption consumed for waking up, and p2 is power consumption for operation of the terminal device per unit time.
It should be noted that the terminal device may determine the power consumption parameter of a signal measurement policy after determining the signal measurement policy. The terminal device may also determine the power consumption parameter of each signal measurement policy after determining the multiple signal measurement policies. In the embodiments of the present application, this is not particularly limited.
Step S1202: and the terminal equipment determines a cell measurement mode with small power consumption parameters to perform cell measurement based on the first power consumption parameter and the second power consumption parameter.
And under the condition that the first power consumption parameter is smaller than the second power consumption parameter, the terminal equipment carries out signal measurement at a first measurement position and a second measurement position which are determined from front to back in a discontinuous reception cycle. And under the condition that the first power consumption parameter is larger than the second power consumption parameter, the terminal equipment carries out signal measurement at a first measurement position and a second measurement position which are determined from back to front in the discontinuous reception period.
It should be noted that the terminal device may also determine the first measurement position by other manners, so as to determine the signal measurement policy, for example, randomly determine the first measurement position, or determine the first measurement position according to the frequency band corresponding to each cell, which is not specifically limited in this embodiment of the application. The terminal device can determine a signal measurement policy with the minimum power consumption from among the plurality of signal measurement policies through the above-described steps S1201 to S1202.
In the embodiment of the application, the terminal device determines the first time window from different positions so as to obtain different signal measurement strategies, determines the signal measurement strategy with the minimum power consumption parameter by determining the power consumption parameter corresponding to each signal measurement strategy, and performs signal measurement on a plurality of cells based on the first measurement position and the second measurement position corresponding to the signal measurement strategy, so that the power consumption of the signal measurement is further reduced, and the standby time of the terminal device is prolonged.
It should be noted that the steps S301 to S302, S701 to S702, and S1201 to S1202 for determining the cell measurement position may be executed by the terminal device, or may be executed by the network device, and accordingly, when the process is executed by the network device, the network device receives resource configuration information of a plurality of cells sent by the terminal device, determines the measurement position of each cell through the steps, and sends the determined measurement position to the terminal device. Accordingly, the terminal device receives the measurement position of each cell sent by the network device, and performs cell measurement based on the measurement position of each cell.
In the embodiment of the application, through a plurality of time windows for measuring the first cell in the DRX cycle, the first cell requiring signal measurement in the time window is measured at the first measurement position, and the second cell is measured at the second measurement position, so that signal measurement does not need to be performed according to the currently camped cell, thereby avoiding the problem of long waiting time caused by missing the measurement position of the first cell, further reducing the waiting time of the terminal device, and improving the standby time of the terminal device.
Based on the foregoing embodiment, after determining multiple cell measurement strategies, for each cell measurement strategy, the terminal selects a cell measurement based on the power consumption parameter, and with reference to fig. 13, the process includes:
1301. determining a first time window of the first cell from front to back;
1302. whether the time windows of other first cells are overlapped with the first time window exists;

1305. whether the first cells are all configured with measurement positions;
