Technical field

This application relates to the field of communication technology, and in particular to a network system, measurement method, electronic equipment, communication device, chip, and computer storage medium.

Background technique

In the wireless communication system, the terminal equipment uses the synchronization channel to perform cell search and cell measurement.

In the Long Term Evolution (LTE) system, the synchronization signal includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The specific design is shown in Figure 1, the period of the synchronization signal It is 5ms, and the network device sends a synchronization signal on a specified subframe, and the length of one subframe is 1ms. For example, a network device sends a synchronization signal in subframe 0 and a synchronization signal in subframe 5.

In the new radio (NR) system, the synchronization signal includes synchronization signal and PBCH block (SSB). The cycle design of SSB is more flexible. The cycle of SSB can be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms. Multiple SSBs can be sent in one cycle, but all SSBs are sent in one 5ms to form an SSB burst. For example, if the SSB cycle is 20ms, one cycle includes 4 5ms, and all SSBs are sent in one 5ms, and no SSB is sent in the other 3 5ms. In FIG. 2, the SSB period corresponding to cell 0 to cell 3 is 20 ms, and the positions of the SSB corresponding to cell 0 to cell 3 may have four situations as shown in FIG. 2. Therefore, for the same SSB cycle, the location of the SSB can be different.

In order to ensure business continuity, when the terminal device moves to the edge of the cell, the network device will issue measurement control tasks such as inter-system measurement and inter-frequency measurement. According to the capabilities of the terminal device, the measurement control tasks issued by the network device are divided into two categories, one is gap measurement, and the other is no gap measurement. Among them, if the terminal device has multiple sets of radio frequency channels that can support receiving and sending signals on the serving cell, and at the same time support receiving signals on different frequencies or neighboring cells of different systems, the terminal device supports the No gap measurement method to measure the different frequencies or neighboring cells of different systems. Area signal. Otherwise, the terminal equipment needs to use the gap measurement method to measure the signals of the different frequency or the neighboring cell of the different system. At this time, the terminal equipment stops the signal transmission and reception on the serving cell within the measurement window, and adjusts the radio frequency path to the different frequency or the frequency point of the different system. Receive signals of different frequencies or adjacent areas of different systems.

As shown in Figure 3, assuming that the measurement window repetition period is 40ms, the measurement window length is 6ms, and the SSB period is 20ms, when the measurement window includes the SSB transmission time period corresponding to the cell, for example, cell0, the terminal device can obtain the measurement of the cell result. When the measurement window does not include the SSB transmission time period corresponding to the cell, the terminal device cannot detect the cell, such as cell1 to cell3.

It can be seen that, in the prior art, there is a situation that the terminal device cannot detect the cell because the measurement window may not include the SSB transmission time period of the cell. Therefore, the terminal device will report fewer cell measurement results. It is helpful for the terminal equipment to switch to a cell with better signal quality.

In addition, the embodiments of the present application may also be applicable to other future-oriented communication technologies. The network architecture and business scenarios described in this application are intended to explain the technical solutions of this application more clearly, and do not constitute a limitation on the technical solutions provided by this application. Those of ordinary skill in the art will know that with the evolution of the network architecture and new business scenarios The technical solutions provided in this application are equally applicable to similar technical problems.

The following briefly introduces the main prior art involved in this application.

The configuration parameters of the measurement window mainly include: measurement gap repetition period (MGRP), measurement gap length (MGL), and the unit is ms. The following table 1 is the measurement window pattern (gap pattern) specified in LTE protocol 36.133, among which pattern 0,1 is the most commonly used, and the following table 2 is part of the gap pattern specified in NR protocol 38.133.

Table 2

Gap PatternId	MGL(ms)	MGRP(ms)	Tinter1(ms)
0	6	40	60
1	6	80	30

Therefore, according to the existing agreement, MGRP has only 4 options of 20ms, 40ms, 80ms, and 160ms. The maximum value of MGL is 6ms. The network equipment can semi-statically configure the measurement window through radio resource control (Radio Resource Control, RRC) signaling.

The network equipment can configure the terminal equipment to measure multiple cells with different frequencies or cells with different systems, where these cells can share a gap configuration. Among them, a different system cell is also called a different radio access technology (radio access technology, RAT) cell, such as a 4G cell, a 3G cell, and so on. According to the performance requirements of each frequency point or RAT, the terminal device may perform multiple measurements on the frequency point or the RAT within _{the T Identify_Inter that meets the requirements of the protocol.}

Exemplarily, for each inter-frequency frequency point, the protocol stipulates that the terminal equipment must complete the measurement within the following time:

Among them, T _{Identify_I} represents the total time of _inter- frequency measurement, T Basic_Identify_Inter represents the basic time of _inter- frequency measurement, T Basic_Identify_Inter = 480ms; T _{inter1 represents the minimum available time for inter-} frequency and inter-system measurement within 480ms. For specific values, see Table 2; CSSF _{E-UTRA, NSA} represents the number of secondary cells (secondary cells, Scells) to be tested.

For example, the gap configuration is MGL=6ms, MGRP=40ms, and one Scell to be tested, then T _{Identify_Inter} =480*480/60*1=3840ms.

In addition, the terminal device can perform joint processing on the measurement data of multiple gaps of the same frequency point or RAT to increase the robustness of the measurement. The terminal device can also determine the time and sequence of each frequency point or RAT measurement by itself according to the number of frequency points or RATs to be measured and the signal strength of the frequency points or RATs to be measured.

The prior art also provides a measurement method to solve the problem that the measurement window may not include the SSB transmission time period of the cell, which may cause the terminal equipment to fail to detect the cell. The core idea of this method is: network equipment configuration Two or more measurement window offsets (gap offset), where the gap offset is used to configure the starting position of the measurement window. For example, when the SSB cycle is 20 ms, theoretically 4 different gap offsets need to be configured to cover all possible positions of the SSB. If you need to measure multiple frequency points at the same time, and the SSB cycles of different frequency points are not consistent, for example, the SSB cycle of one frequency point is 20ms, and the SSB cycle of one frequency point is 40ms, then the number of gap offsets that need to be configured are 4 and respectively. 8. Therefore, the disadvantage of the above method is that it has a greater impact on the implementation of the terminal device side and the gap resource allocation on the network device side.

It should be understood that in this application, the following only takes the synchronization signal as SSB as an example for description. With the change of technology, the synchronization signal may also change, and the changed synchronization signal may also be applicable to the embodiments of the present application. This application does not limit this. In addition, the method provided in the embodiment of the present application is also applicable to communication systems below 5G.

Based on this, the embodiments of the present application provide a measurement method to solve the problem that the terminal device cannot detect the cell because the measurement window does not include the SSB transmission time period of the cell. Using the method provided by the embodiments of the present application can realize the measurement of the possible positions of each SSB cycle without having a major impact on the gap resource allocation, and there is no need to modify the requirement _{of the measurement time T Identify_Inter of the protocol.}

As shown in FIG. 5, an embodiment of the present application provides a measurement method, which can be applied to a network system, and the system includes a terminal device, a first network device, and a second network device. The terminal device is connected to the first network device through the first link, and the cell under the jurisdiction of the second network device includes the first frequency point cell.

The method specifically includes:

Step 500: The first network device sends the second information to the terminal device.

Wherein, the second information includes the repetition period of the first measurement window, the repetition period of the first measurement window is 10M+5 milliseconds, and M is a positive integer.

Exemplarily, the repetition period of the first measurement window is 25 ms, or the repetition period of the first measurement window is 45 ms. It should be understood that this is only an example and not a limitation of the application.

Exemplarily, the second information may be carried by a measurement configuration field (meas config) in a radio resource control reconfiguration (radio resource control reconfiguration) message. For example, the measurement configuration field may include information such as the repetition period of the first measurement window, the length of the first measurement window, and the offset of the first measurement window.

Step 510: The first network device sends the first information to the terminal device. The first information instructs the terminal device to measure the cell of the first frequency point.

Exemplarily, the first information may instruct the terminal device to measure multiple frequency point cells to be measured. For example, the first information may also instruct the terminal device to measure the second frequency cell at the same time.

In some embodiments, the first information may be actively triggered by the first network device, or the terminal device may send a request to the first network device. The request is used to request neighboring cell measurement, and the first network device responds to the terminal device’s Request to send the first information to the terminal device. For example, if the first network device detects that the signal quality of the current cell is lower than the threshold, or the signal strength is lower than the threshold, or other parameters meet preset conditions, the first network device sends the first information to the terminal device.

Exemplarily, when the terminal device moves to the edge of the cell, the communication quality between the terminal device and the first network device deteriorates, and the first network device sends the first information to the terminal device.

In some embodiments, the first information and the second information may be sent separately, for example, the first information may be sent first, or the second information may be sent first. Alternatively, the first information and the second information may be sent at the same time. This application does not limit this.

Step 520: The terminal device searches for the synchronization signal of the first frequency point cell according to the repetition period of the first measurement window.

It can be understood that, according to the repetition period of the first measurement window, the terminal device searches for the synchronization signal of the cell at the first frequency point in the first measurement window every time it reaches the first measurement window.

Wherein, the number of the first frequency point cell may be one or more, and the synchronization signal period corresponding to the first frequency point cell is generally a synchronization signal period. The synchronization signals corresponding to the multiple first frequency point cells may be located at the same location or at different locations.

For example, assuming that the SSB period corresponding to the cell at the first frequency point is 20ms, there are 4 possible locations of the SSB with a period of 20ms. There may be but not limited to the following scenarios:

Scenario 1: As shown in Figure 2, the number of cells at the first frequency point is 4, and the positions of the SSBs corresponding to cell0 to cell3 are different from each other.

Scenario 2: As shown in Figure 6(a), the number of cells at the first frequency point can be one, and the SSB corresponding to cell0 is located in the first possible position among the four possible positions of the SSB (that is, the first 5ms).

Scenario 3: As shown in Figure 6(b), the number of cells at the first frequency point can be two, where the SSB corresponding to cell0 is located in the first possible position among the four possible positions of the SSB (that is, the first 5ms ), the SSB corresponding to cell1 is located in the second possible position (that is, the second 5ms) among the four possible positions of the SSB.

Scenario 4: In Figure 6(c), the number of cells at the first frequency point can be 5, where the locations of the SSBs corresponding to cell0 to cell3 are different from each other, and the location of the SSB corresponding to cell4 is the same as that of the SSB corresponding to cell0. The location is the same.

It should be understood that the foregoing SSB cycle and the listed possible scenarios are only examples, and are not a limitation of this application.

Exemplarily, as shown in Figure 7(a), when the SSB period corresponding to the first frequency cell is 20ms and MGRP=25ms, the terminal device can search for the SSB corresponding to cell0 through the first gap, and through the second gap The gap can search for the SSB corresponding to cell1, the SSB corresponding to cell2 can be searched through the third gap, and the SSB corresponding to cell3 can be searched through the fourth gap. Therefore, through 4 consecutive gaps, all possible positions of the SSB with a traversal period of 20 ms can be realized. Among them, cell0 to cell3 are the first frequency point cells.

As shown in Figure 7(b), when the SSB period corresponding to the first frequency cell is 20ms and MGRP=45ms, the terminal device can search for the SSB corresponding to cell0 through the first gap, and can search through the second gap For the SSB corresponding to cell1, the SSB corresponding to cell2 can be searched through the third gap, and the SSB corresponding to cell3 can be searched through the fourth gap. Among them, only the first gap and the second gap are shown in Fig. 7(b), and the third gap and the fourth gap are omitted and not shown. Therefore, through 4 consecutive gaps, all possible positions of the SSB with a traversal period of 20ms can be realized. Among them, cell0 to cell3 are the cells whose frequency point is the first frequency point.

It can be seen from the above that based on the period of the synchronization signal corresponding to the cell at the first frequency point and the repetition period of the first measurement window, the least common multiple of the period of the synchronization signal corresponding to the cell at the first frequency point and the repetition period of the first measurement window can be calculated, Further, according to the least common multiple, the number of first measurement windows required for the possible positions of the synchronization signal whose traversal period is the period of the synchronization signal corresponding to the first frequency point cell can be determined.

For example, when the SSB period is 20ms and MGRP=25ms, the least common multiple is 100ms. Furthermore, since MGRP=25ms, it can be determined that the number of gaps required to realize all possible positions of the SSB with a traversal period of 20ms is 100/25=4 indivual.

For another example, when the SSB period is 20ms and MGRP=45ms, the least common multiple is 180ms. Furthermore, since MGRP=45ms, it can be determined that the number of gaps required to realize all possible positions of the SSB with a traversal period of 20ms is 180/45= 4.

For another example, when the period of the SSB is 160ms and MGRP=25ms, the least common multiple is 800ms. Furthermore, since MGRP=25ms, it can be determined that the number of gaps required to realize all possible positions of the SSB with a traversal period of 160ms is 800/25. = 32.

It is understandable that the time interval for the terminal equipment to search for the same cell twice can be determined according to the period of the synchronization signal corresponding to the cell at the first frequency point and the repetition period of the first measurement window. This time interval corresponds to the cell at the first frequency point. The least common multiple of the period of the synchronization signal and the repetition period of the first measurement window. It can also be described as that the number of first measurement windows between the terminal equipment searching for the same cell twice is determined according to the period of the synchronization signal corresponding to the cell of the first frequency point and the repetition period of the first measurement window. The number of a measurement window is the quotient of the period of the synchronization signal corresponding to the cell at the first frequency point and the least common multiple of the repetition period of the first measurement window and the repetition period of the first measurement window.

For example, as shown in Figure 7(a), when the SSB period corresponding to the first frequency cell is 20ms and MGRP=25ms, it is assumed that the terminal device can search for the SSB corresponding to cell0 for the first time through the first gap, and pass the first gap. Two gaps can search for the SSB corresponding to cell1 for the first time, the third gap can search for the SSB corresponding to cell2 for the first time, and the fourth gap can search for the SSB corresponding to cell3 for the first time, and the terminal device passes The fifth gap can search for the SSB corresponding to cell0 for the second time, the sixth gap can search for the SSB corresponding to cell1 for the second time, and the seventh gap can search for the SSB corresponding to cell2 for the second time. A gap can search for the SSB corresponding to cell3 for the second time. Among them, the time interval between the terminal equipment searching for the SSB corresponding to cell0 for the first time and the terminal equipment searching for the SSB corresponding to cell0 for the second time is 100ms, the terminal equipment searching for the SSB corresponding to cell0 for the first time and the terminal equipment searching for the second time The number of gaps between the SSB corresponding to cell0 is 4.

For another example, when MGRP=25ms and the SSB period is 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms, the number of gaps between the same cell that the terminal device searches for two adjacent times is 1, 2, and 2 respectively. 4, 8, 16, 32.

Step 530: The terminal device sequentially saves the measurement data respectively corresponding to the multiple first measurement windows, and obtains the measurement result of the first frequency point cell according to the measurement data respectively corresponding to the multiple first measurement windows.

In a possible design, the terminal device may also determine the first duration according to the repetition period of the first measurement window and the maximum possible period of the synchronization signal, and the terminal device sequentially saves the multiple first measurement windows within the first duration. Corresponding measurement data. Exemplarily, after the first time period is exceeded, the terminal device stops searching for the synchronization signal of the first frequency point cell, and the terminal device may switch to search for the synchronization signal of the next frequency point cell to be measured or end the search for the synchronization signal. In addition, when the terminal device does not search for the synchronization signal of the first frequency point cell within the first time period, the terminal device stops searching for the synchronization signal of the first frequency point cell, and the terminal device can switch to search for the next frequency point cell to be measured Sync signal or end search sync signal.

In some embodiments, the first duration may be N times the least common multiple of the repetition period of the first measurement window and the maximum possible period of the synchronization signal, and N is a positive integer. The value of N can be determined according to the capabilities of the terminal device itself or the measurement requirements configured by the network device. For example, when N=1, the first duration may be the least common multiple of the repetition period of the first measurement window and the maximum period of the synchronization signal. The maximum possible period of the synchronization signal can be determined according to the protocol. For example, the value of the SSB period specified in the current protocol can be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms. As shown in Table 1, the maximum possible period of the synchronization signal Is 160ms.

For example, the current protocol stipulates that the maximum possible period of the SSB is 160ms. When MGRP=25ms, the terminal device determines that the number of gaps required to realize all possible positions of the SSB with a traversal period of 160ms is 32, that is, 800ms. When the first time length is N*800ms, in the first time length, if the terminal device searches for the synchronization signal of the first frequency point cell, the terminal device sequentially saves the measurement data corresponding to the multiple first measurement windows in the first time length When the first time period is exceeded, the terminal device ends searching for synchronization signals or switches to search for synchronization signals of the next frequency point cell to be measured. In the first time period, if the terminal device cannot search for the synchronization signal of the first frequency point cell, when the first time period is exceeded, the terminal device ends the search or switches to search for the synchronization signal of the next frequency point cell to be measured.

In some instances, the measurement data corresponding to the multiple first measurement windows sequentially saved by the terminal device may refer to the measurement data corresponding to the multiple first measurement windows sequentially saved by the terminal device within the first time period. In other examples, the terminal device may determine the total number K of the first measurement windows by itself or configure the first network device through the first network device. The terminal device may sequentially save the measurement data corresponding to the K first measurement windows. The measurement data respectively corresponding to the multiple first measurement windows may refer to the measurement data respectively corresponding to the K first measurement windows. It should be understood that the specific form of the measurement data corresponding to the multiple first measurement windows sequentially stored by the terminal device is only an example, and is not a limitation of the embodiment of the present application.

Further, for the measurement data corresponding to the multiple first measurement windows sequentially stored by the terminal device, the terminal device may adopt but not limited to the following processing methods to obtain the measurement results of the first frequency point cell:

Manner 1: The terminal device obtains the period of the synchronization signal corresponding to the first frequency point cell. The terminal device may determine the first value according to the repetition period of the first measurement window and the period of the synchronization signal corresponding to the first frequency point cell. number. Further, the terminal device groups the measurement data corresponding to the multiple first measurement windows according to the storage order and the first value of the measurement data respectively corresponding to the multiple first measurement windows to obtain several groups of measurement data. Using the above method, the terminal device can determine which of the stored measurement data is for the location of the same synchronization signal, and group these measurement data into one group, that is, each set of measurement data corresponds to the location of a synchronization signal. Then, the terminal device performs joint processing on each set of measurement data to obtain the measurement result of the cell at the first frequency point. Wherein, the measurement result of the cell at the first frequency point includes the processing result after joint processing corresponding to each set of measurement data in the plurality of sets of measurement data.

Among them, the joint processing may specifically refer to incoherent cumulative joint detection, or other possible processing methods, which are not limited in this application.

Wherein, the terminal device may adopt but not limited to the following method A and method B to determine the period of the synchronization signal corresponding to the first frequency point.

Method A: Since the SSB cycles of cells with the same frequency point are largely consistent, as long as the terminal device has camped on any first frequency point cell (hereinafter referred to as the first cell) in history, the terminal device will receive The system message of the first cell (for example, system information block (SIB) 1), the system message includes the period of the synchronization signal corresponding to the first cell. The terminal device saves the system information of the first cell, and then can determine the period of the synchronization signal corresponding to the first cell through the system message of the first cell, as the period of the synchronization signal corresponding to the first frequency point cell. Among them, the system information of the first cell stored by the terminal device may also be referred to as historical prior information. For example, a terminal device has camped on cell 1, and cell 1 is a cell of frequency 1. The terminal device saves the SIB1 of cell 1, and the terminal device can determine the SSB corresponding to frequency 1 according to the SSB period corresponding to cell 1 included in the SIB1 cycle.

Method B: When the terminal device searches for the synchronization signal of the second cell, the terminal device receives a system message from the second cell, and the system message includes the period of the synchronization signal corresponding to the second cell. Among them, the second cell is a first frequency point cell. Since the periods of the synchronization signals of the cells having the same frequency point are likely to be consistent, the terminal device may use the period of the synchronization signal corresponding to the second cell as the period of the synchronization signal corresponding to the first frequency point. For example, when the terminal device searches for a cell of frequency point 1, the terminal device finds a cell in a gap, and further, the terminal device receives the SIB1 of the cell, and determines frequency point 1 according to the SSB period corresponding to the cell included in SIB1 The corresponding SSB period.

Fig. 8 shows an example of mode 1, which is not a limitation of this application. The terminal equipment determines that the SSB period corresponding to the cell at the first frequency point is 20ms according to the historical prior information, and there are 4 possible locations of the SSB with the period of 20ms. When MGRP=25ms, the terminal equipment can search for the first time through the first gap To the SSB corresponding to cell0, the SSB corresponding to cell1 can be found for the first time through the second gap, the SSB corresponding to cell2 can be found for the first time through the third gap, and cell3 can be found for the first time through the fourth gap. For the corresponding SSB, the SSB corresponding to cell0 can be found for the second time through the fifth gap, the SSB corresponding to cell1 can be found for the second time through the sixth gap, and the SSB corresponding to cell2 can be found for the second time through the seventh gap. SSB, through the 8th gap, the SSB corresponding to cell3 can be searched for the second time. The terminal device saves the measurement data corresponding to the above 8 gaps. Further, the terminal device can determine that the number of gaps between the SSBs that search for the same cell twice is 4 according to the period of the SSB and MGRP=25ms, and the terminal device groups the measurement data corresponding to the 8 gaps. Obtain 4 sets of measurement data, each set of measurement data corresponds to a possible location of SSB. Among them, the first group of measurement data includes the measurement data corresponding to the first gap and the measurement data corresponding to the fifth gap. 5ms). The second set of measurement data includes the measurement data corresponding to the second gap and the measurement data corresponding to the sixth gap. ). The third set of measurement data includes the measurement data corresponding to the third gap and the measurement data corresponding to the seventh gap. That is, the third set of measurement data corresponds to the third possible position of the 4 possible positions of the SSB (that is, the third 5ms ). The fourth group of measurement data includes the measurement data corresponding to the fourth gap and the measurement data corresponding to the eighth gap. ). The terminal device performs joint processing on the first group of measurement data, and obtains the processing result after the joint processing corresponding to the first group of measurement data. Among them, if the SSB is located in the first possible position (that is, the first 5ms) of the four possible positions of the SSB, there is only one cell, and the terminal equipment performs joint processing through the first group of measurement data to obtain the corresponding group of the first group of measurement data. The processing result after the joint processing, the processing result includes the measurement result corresponding to cell0. If there are multiple SSBs in the first 5ms cell, suppose there are 2 SSBs in the first 5ms cell, cell0 and cell4 respectively. Among them, the signal strength of the SSB corresponding to cell0 is stronger, and the signal of the SSB corresponding to cell4 The strength is weak. Therefore, the terminal device can only determine the synchronization signal corresponding to cell0, and by performing joint processing on the first group of measurement data, the terminal device can also obtain the measurement result corresponding to cell4. At this time, the processing result after the joint processing corresponding to the first group of measurement data includes the measurement result corresponding to cell0 and the measurement result corresponding to cell4. Through the above-mentioned joint processing, the terminal equipment can discover new cells and increase the robustness of the measurement.

In the same way, the terminal device can obtain the processing result after the joint processing corresponding to the second group of measurement data, the processing result after the joint processing corresponding to the third group of measurement data, and the processing result after the joint processing corresponding to the fourth group of measurement data. The terminal device uses the joint processing results corresponding to the four sets of measurement data as the measurement results of the first frequency point cell.

Among them, in Figure 8, the 7th gap and the 8th gap are not drawn. It should be understood that the terminal device only obtains 8 measurement data through the gap as an example for illustration, and the terminal device may obtain more measurements. Data, based on more measurement data for joint processing.

Manner 2: The terminal device may pre-configure the traversal sequence of possible periods of the synchronization signal, or randomly generate the traversal sequence of the possible periods of the synchronization signal. It is assumed that the first synchronization signal period is the period of the synchronization signal corresponding to the first frequency point cell, where the first synchronization signal period is determined according to the traversal sequence of possible periods of the synchronization signal. Further, the terminal device may use the method provided in the above manner 1 to group the measurement data corresponding to the multiple first measurement windows sequentially stored by the terminal device to obtain several groups of measurement data, and perform joint processing on each group of measurement data. At this time, the following possible situations may be included:

The first possible situation: if a new cell is discovered through joint processing of any set of measurement data in several sets of measurement data, it indicates that the first synchronization signal period is correct. Further, the terminal device may verify whether the period of the synchronization signal corresponding to the first frequency point cell is the first synchronization signal period by receiving the system message of the cell.

The second possible situation: if no new cell is found through joint processing of several sets of measurement data, the first synchronization signal period is wrong. At this time, the terminal device can repeat the above process by adopting the next possible period of the synchronization signal after the first synchronization signal period according to the traversal sequence of the possible periods of the synchronization signal, until the synchronization signal period and the first frequency point corresponding to the first frequency point cell are determined. The measurement result corresponding to the cell.

For example, the terminal device searches for the cell under frequency 1. According to the preset SSB possible cycle traversal sequence, the terminal equipment first assumes that the SSB cycle corresponding to the cell at frequency 1 is 20ms, because the possible locations of SSBs with a cycle of 20ms are 4 Therefore, the measurement data corresponding to multiple gaps stored in sequence by the terminal device are divided into 4 groups. Among them, for the first group of measurement data, the terminal device did not search for the synchronization signal in the first gap, and did not find the synchronization signal in the fifth gap. After searching for the synchronization signal, the terminal device performs joint processing on the measurement data corresponding to the first gap and the measurement data corresponding to the fifth gap. If a new cell is discovered through the joint processing of the terminal equipment, it indicates that the SSB period corresponding to the cell at frequency point 1 is 20 ms.

If no new cell is found by the terminal device through the joint processing of the 4 sets of measurement data, it is wrong to assume that the SSB period corresponding to the cell at frequency 1 is 20 ms. Further, the terminal device may repeat the above process according to the preset possible traversal sequence of the SSB. Exemplarily, when the SSB period corresponding to the cell at frequency point 1 is assumed to be 10 ms, the terminal device performs joint processing on the measurement data corresponding to the first gap and the measurement data corresponding to the third gap, or, at the assumption frequency point 1 When the SSB period corresponding to the cell of is 40 ms, the terminal device performs joint processing on the measurement data corresponding to the first gap and the measurement data corresponding to the ninth gap.

Step 540: The terminal device sends the measurement result of the first frequency point cell to the first network device.

It is understandable that after the terminal device has completed searching for the first frequency point cell, the terminal device may continue to search for other frequency point cells to be measured. The terminal device may report the measurement results of the measured cells at multiple frequency points to the network device together, or report to the network device separately, which is not limited in this application. Further, the network device can select a cell with better signal quality for the terminal device to perform handover according to the measurement results of the cells at multiple frequency points reported by the terminal device.

As shown in FIG. 9, an embodiment of the present application provides a measurement method, and the method may be applied to a network system, which includes a terminal device, a first network device, and a second network device. The terminal device is connected to the first network device through the first link, and the cell under the jurisdiction of the second network device includes the first frequency point cell.

The method specifically includes:

Step 900: The first network device sends the first information to the terminal device. The first information instructs the terminal device to measure the cell of the first frequency point.

It should be understood that, for the specific content of step 910, reference may be made to the related description of step 510 in the embodiment shown in FIG. 5, and repetitions are not repeated here.

Step 910: The terminal device determines the first information.

The first information includes the repetition period of the first measurement window, the repetition period of the first measurement window is 10M+5 milliseconds, and M is a positive integer.

It should be understood that the difference from the embodiment shown in FIG. 5 is that in the embodiment shown in FIG. 9, the terminal device actively adds a measurement window. Exemplarily, the network device configures the second measurement window for the terminal device. In order to realize that the terminal device can measure more cells of the first frequency point and/or a certain cell of the first frequency point cells, the terminal device actively adds the first measurement window. Measurement window. Therefore, the method provided by the embodiment shown in FIG. 9 can be used to realize that the existing protocol does not need to be modified.

In a possible design, when the terminal device has not searched for the synchronization signal of the first frequency cell according to the repetition period of the second measurement window, or has searched for the synchronization signal of a first frequency cell, the terminal device determines the first information .

For example, as shown in Figure 10, when the repetition period of the second measurement window is 40 ms, the terminal device cannot search for the SSB corresponding to cell 2 in the second measurement window based on the repetition period of the second measurement window, but can only search for the cell 1 corresponds to the SSB, the terminal device can actively add the first measurement window, and the repetition period of the first measurement window is 25ms. Among them, cell 1 and cell 2 are cells of the same frequency. The second measurement window is a measurement window configured by the network device for the terminal device according to the existing protocol.

In a possible design, when the terminal equipment determines that the number of cells at the first frequency point is K1, and the number of cells at the first frequency point searched by the terminal equipment according to the repetition period of the second measurement window is K2, the terminal equipment determines The first information, where K1>K2, K1≥1, and K2≥0.

For example, as shown in Figure 10, when the repetition period of the second measurement window is 40 ms, the terminal device cannot search for the SSB corresponding to cell 2 in the second measurement window based on the repetition period of the second measurement window, but can only search for the cell 1 corresponds to the SSB, and the terminal device knows that the number of cells under this frequency point is 2, the terminal device can actively add the first measurement window, and the repetition period of the first measurement window is 25ms. Among them, cell 1 and cell 2 are cells of the same frequency. The second measurement window is a measurement window configured by the network device for the terminal device according to the existing protocol.

Step 920: The terminal device searches for the synchronization signal of the first frequency point cell according to the repetition period of the first measurement window.

Exemplarily, as shown in FIG. 9, after the terminal device adds the first measurement window, the terminal device can search for the SSB of cell 2 based on the repetition period of the first measurement window.

Step 930: The terminal device sequentially saves the measurement data respectively corresponding to the multiple first measurement windows, and obtains the measurement result of the first frequency point cell according to the measurement data respectively corresponding to the multiple first measurement windows.

Step 940: The terminal device sends the measurement result of the first frequency point cell to the first network device.

It should be understood that, for step 920 to step 940, reference may be made to the related description of step 520 to step 540 in the embodiment shown in FIG. 5, and the repetitive parts will not be repeated.
