Description

Measuring method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a measurement method and apparatus.

Background

In a wireless communication system, a terminal device performs cell search and cell measurement using a synchronization channel.

In a Long Term Evolution (LTE) system, synchronization signals include Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS), and specifically, as shown in fig. 1, a period of a synchronization signal is 5ms, a network device transmits a synchronization signal on a predetermined subframe, and a length of 1 subframe is 1 ms. For example, the network device transmits the synchronization signal in subframe 0 and transmits the synchronization signal in subframe 5.

In a New Radio (NR) system, a synchronization signal includes a synchronization signal and PBCH block (SSB), the period design of the SSB is flexible, and the period of the SSB may be 5ms, 10ms, 20ms, 40ms, 80ms, or 160 ms. Multiple SSBs may be sent in one cycle, but all SSBs are sent collectively in 15 ms, forming one SSB set (SSB burst). For example, if the SSB period is 20ms, one period includes 45ms, and all SSBs are concentrated in 1 of the 5ms for transmission, and no SSB is transmitted in the other 3 5 ms. In fig. 2, the SSB periods corresponding to the cells (cells) 0 to 3 are 20ms, and the SSBs corresponding to the cells 0 to 3 may be located in four cases as shown in fig. 2. Thus, the location of the SSBs may be different for the same SSB period.

In order to ensure service continuity, when the terminal device moves to the edge of a cell, the network device issues measurement control tasks such as inter-system measurement and inter-frequency measurement. According to the capability of the terminal device, the measurement control tasks issued by the network device are divided into two categories, one is measurement window (gap) measurement, and the other is measurement-free window (No gap) measurement. If the terminal device has multiple sets of radio frequency paths, and can support receiving and transmitting signals on the serving cell and simultaneously support receiving signals on the pilot frequency or inter-system neighbor cells, the terminal device supports an No gap measurement mode to measure signals of the pilot frequency or inter-system neighbor cells. Otherwise, the terminal device needs to measure the signal of the different-frequency or different-system neighbor cell by using a gap measurement mode, at this time, the terminal device stops receiving and sending the signal on the serving cell in the measurement window, adjusts the radio frequency channel to the frequency point of the different-frequency or different-system neighbor cell, and receives the signal of the different-frequency or different-system neighbor cell.

As shown in fig. 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 result of the cell. When the measurement window does not include the SSB transmission time period corresponding to the cell, the terminal device cannot detect the cell, for example, cell1 to cell 3.

Therefore, in the prior art, the measurement window may not include the SSB sending time period of the cell, so that the terminal device may not measure the cell, and therefore, the measurement results of the cell reported by the terminal device are less, which is not favorable for the terminal device to switch to the cell with better signal quality.

And the terminal equipment searches the synchronous signal of the first frequency point cell according to the repetition period of the first measurement window.

And the terminal equipment groups the measurement data respectively corresponding to the first measurement windows according to the storage sequence and the first numerical value of the measurement data respectively corresponding to the first measurement windows to obtain a plurality of groups of measurement data.

Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

The network element involved in the embodiment of the present application includes a network device and a terminal device, as shown in fig. 4.

The network device is an entity, such as a new generation base station (gbnodeb), in the network side for transmitting or receiving signals. The network device may be a device for communicating with the mobile device. The network device may be an AP in a Wireless Local Area Network (WLAN), a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB, or eNodeB) in a Long Term Evolution (LTE), or a relay station or Access point or Access backhaul Integration (IAB), or a network device in a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved public mobile network (PLMN ) network or a network NR in a network system. In the embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell. Furthermore, the network device may be other means for providing wireless communication functionality for the terminal device, where possible. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. For convenience of description, in the embodiments of the present application, an apparatus for providing a wireless communication function for a terminal device is referred to as a network device.

The terminal device may be a wireless terminal device capable of receiving network device scheduling and indication information, and the wireless terminal device may be a device providing voice and/or data connectivity to a user, or a handheld device having a wireless connection function, or other processing device connected to a wireless modem. The terminal device may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving (self-driving), a wireless terminal device in remote surgery (remote medical supply), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), a wearable device, a terminal device in a next-generation communication system, and the like.

In addition, the embodiment of the application can also be applied to other communication technologies facing the future. The network architecture and the service scenario described in this application are for more clearly illustrating the technical solution of this application, and do not constitute a limitation to the technical solution provided in this application, and it can be known by those skilled in the art that the technical solution provided in this application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of new service scenarios.

The main prior art to which this application relates is briefly described below.

The configuration parameters of the measurement window mainly include: measurement window repetition period (MGRP), measurement window length (MGL), in units of ms. Table 1 below shows the measurement window pattern (gap pattern) specified in the LTE protocol 36.133, where

patterns

0 and 1 are most commonly used, and table 2 below shows part of the content of the gap pattern specified in the NR protocol 38.133.

TABLE 1

TABLE 2

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

Therefore, according to the existing protocol, the MGRP has only 20ms, 40ms, 80ms, 160ms, 4 choices, and the MGL maximum is 6 ms. The network device may configure the measurement window semi-statically through Radio Resource Control (RRC) signaling.

Network deviceThe terminal equipment can be configured to measure a plurality of different frequency point cells or different system cells, wherein the cells can share one gap configuration. Herein, the inter-system cell is also called an inter-Radio Access Technology (RAT) cell, such as a 4G cell and a 3G cell. The terminal equipment can meet the protocol requirement at T according to the performance requirement of each frequency point or RAT_{Identify_Inter}And measuring the frequency point or the RAT for multiple times.

For each pilot frequency point, the protocol specifies that the terminal device needs to complete the measurement within the following time:

wherein, T_{Identify_Inter}Representing the total time of pilot frequency measurement, T_{Basic_Identify_Inter}Indicating the inter-frequency measurement base time, T_{Basic_Identify_Inter}＝480ms；T_inter1The minimum available time of pilot frequency and inter-system measurement in 480ms is shown, and specific values can be seen in table 2; CSSF_E-UTRA,NSAAnd (3) representing the number of secondary cells (Scell) to be tested.

For example, if the gap is configured to have MGL of 6ms and MGRP of 40ms, and a Scell is to be tested, then T is determined_{Identify_Inter}＝480*480/60*1＝3840ms。

In addition, the terminal device may 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 equipment can also determine the time and the sequence of measurement of each frequency point or RAT according to the number of the frequency points or RATs to be measured and the signal intensity of the frequency points or RATs to be measured.

The prior art also provides a measurement method for solving the problem that a terminal device may not detect a cell because a measurement window may not include an SSB transmission time period of the cell, and the core idea of the method is; the network apparatus configures two or more measurement window offsets (gap offsets), wherein the gap offsets are used to configure the starting position of the measurement window. For example, when the SSB period is 20ms, 4 different gap offsets need to be configured in theory to cover all possible SSBs positions. If a plurality of frequency points need to be measured simultaneously and the SSB periods of different frequency points are not consistent, for example, the SSB period of one frequency point is 20ms and the SSB period of one frequency point is 40ms, the number of gap offsets to be configured is 4 and 8, respectively. Therefore, the above method has a disadvantage in that it has a large influence on both the implementation of the terminal device side and the allocation of gap resources of the network device side.

It should be understood that, in the present application, only the synchronization signal is described as an SSB, and the synchronization signal may also change with the change of the technology, and the changed synchronization signal may also be applied to the embodiments of the present application, which is not limited in the present application. In addition, the method provided by the embodiment of the application is also applicable to communication systems below 5G.

Based on this, the embodiments of the present application provide a measurement method, which is used to solve the problem that a terminal device cannot measure a cell because a measurement window does not include an SSB transmission time period of the cell. The method provided by the embodiment of the application can realize the measurement of the possible position of each SSB period, does not generate great influence on the allocation of gap resources, and does not need to modify the measurement time T of the protocol_{Identify_Inter}The requirements of (1).

As shown in fig. 5, an embodiment of the present application provides a measurement method, which may be applied to a network system including a terminal device, a first network device, and a second network device. The terminal equipment is connected to the first network equipment through a first link, and the cells administered by the second network equipment comprise first frequency point cells.

The method specifically comprises the following steps:

step 500: and the first network equipment sends the second information to the terminal equipment.

The second information comprises a 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.

Illustratively, the repetition period of the first measurement window is 25ms, or the repetition period of the first measurement window is 45 ms. It should be understood that this is done by way of example only and is not limiting.

Exemplarily, the second information may be carried by a measurement configuration field (meas configuration) in a radio resource control reconfiguration (radio resource control reconfiguration) message. For example, the measurement configuration field may include information of a repetition period of the first measurement window, a length of the first measurement window, and an 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 equipment to measure the first frequency point cell.

Illustratively, the first information may instruct the terminal device to measure a plurality of frequency point cells to be measured. For example, the first information may also instruct the terminal device to measure the second frequency cell.

In some embodiments, the first information may be an active trigger of the first network device, or may be a request sent by the terminal device to the first network device, where the request is used to request a neighbor cell measurement, and the first network device sends the first information to the terminal device in response to the request of the terminal device. For example, when the first network device detects that the signal quality of the current cell is lower than a threshold, or the signal strength is lower than the threshold, or other parameters meet a preset condition, the first network device sends the first information to the terminal device.

Illustratively, 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 transmits 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 transmitted simultaneously. This is not a limitation of the present application.

Step 520: and the terminal equipment searches the synchronous 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, each time the first measurement window is reached, the terminal device searches for the synchronization signal of the first frequency point cell in the first measurement window.

The number of the first frequency point cells 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 respectively corresponding to the multiple first frequency point cells may be located at the same position or at different positions.

For example, assuming that the SSB period corresponding to the first frequency cell is 20ms, there are 4 possible positions of the SSBs with the period of 20ms, and there may be, but is not limited to, the following scenarios:

scene 1: as shown in fig. 2, the number of the first frequency cells is 4, and the positions of the SSBs corresponding to the cells 0 to 3 are different from each other.

Scene 2: as shown in fig. 6(a), the number of the first frequency point cells may be 1, and the SSB corresponding to the cell0 is located at the first possible position (i.e. the first 5ms) of the 4 possible positions of the SSB.

Scene 3: as shown in fig. 6(b), the number of the first frequency cells may be 2, where the SSB corresponding to the cell0 is located at the first possible position (i.e., the first 5ms) of the 4 possible positions of the SSB, and the SSB corresponding to the cell1 is located at the second possible position (i.e., the second 5ms) of the 4 possible positions of the SSB.

Scene 4: in fig. 6(b), the number of the first frequency cells may be 5, where the positions of the SSBs corresponding to the cells 0 to 3 are different from each other, and the position of the SSB corresponding to the cell4 is the same as the position of the SSB corresponding to the cell 0.

It should be understood that the SSB period and possible scenarios listed above are merely examples and are not limiting of the present application.

For example, as shown in fig. 7(a), when the SSB period corresponding to the first frequency point cell is 20ms and the MGRP is 25ms, the terminal device may search for an SSB corresponding to cell0 through the 1 st gap, may search for an SSB corresponding to cell1 through the 2 nd gap, may search for an SSB corresponding to cell2 through the 3 rd gap, and may search for an SSB corresponding to cell3 through the 4 th gap. Thus, all possible positions of the SSB with a traversal period of 20ms can be achieved by consecutive 4 gaps. The cells 0 to 3 are first frequency cells.

As shown in fig. 7(b), when the SSB period corresponding to the first frequency point cell is 20ms and the MGRP is 45ms, the terminal device may search for the SSB corresponding to the cell0 through the 1 st gap, may search for the SSB corresponding to the cell1 through the 2 nd gap, may search for the SSB corresponding to the cell2 through the 3 rd gap, and may search for the SSB corresponding to the cell3 through the 4 th gap. In fig. 7(b), only the 1 st and 2 nd gaps are shown, and the 3 rd and 4 th gaps are omitted and not shown. Therefore, all possible positions of the SSB with a traversal period of 20ms can be achieved by consecutive 4 gaps. The cells 0 to 3 are cells with the frequency point being the first frequency point.

As can be seen from the above, based on the period of the synchronization signal corresponding to the first frequency point cell and the repetition period of the first measurement window, the least common multiple of the period of the synchronization signal corresponding to the first frequency point cell and the repetition period of the first measurement window may be calculated, and further, the number of the first measurement windows required for traversing the possible positions of the synchronization signal having the period that is the period of the synchronization signal corresponding to the first frequency point cell may be determined according to the least common multiple.

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

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

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

It can be understood that, the time interval between two adjacent searches of the same cell by the terminal device may be determined according to the cycle of the synchronization signal corresponding to the first frequency point cell and the repetition cycle of the first measurement window, where the time interval is the least common multiple of the cycle of the synchronization signal corresponding to the first frequency point cell and the repetition cycle of the first measurement window. The number of the first measurement windows spaced by the terminal device searching for the same cell twice in the vicinity is determined according to the cycle of the synchronization signal corresponding to the first frequency point cell and the repetition cycle of the first measurement window, where the number of the first measurement windows is a quotient of the least common multiple of the cycle of the synchronization signal corresponding to the first frequency point cell and the repetition cycle of the first measurement window.

For example, as shown in fig. 7(a), when the SSB period corresponding to the first frequency point cell is 20ms and the MGRP is 25ms, it is assumed that the terminal device can search for the SSB corresponding to cell0 for the first time through the 1 st gap, can search for the SSB corresponding to cell1 for the first time through the 2 nd gap, can search for the SSB corresponding to cell2 for the first time through the 3 rd gap, and can search for the SSB corresponding to cell3 for the first time through the 4 th gap, the terminal device can search for the SSB corresponding to cell0 for the second time through the 5 th gap, can search for the SSB corresponding to cell1 for the second time through the 6 th gap, can search for the SSB corresponding to cell2 for the second time through the 7 th gap, and can search for the SSB corresponding to cell3 for the second time through the 8 th gap. The time interval between the SSB corresponding to the cell0 searched by the terminal device for the first time and the SSB corresponding to the cell0 searched by the terminal device for the second time is 100ms, and the number of gap between the SSB corresponding to the cell0 searched by the terminal device for the first time and the SSB corresponding to the cell0 searched by the terminal device for the second time is 4.

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

Step 530: the terminal equipment sequentially stores the measurement data corresponding to the first measurement windows respectively, and obtains the measurement result of the first frequency point cell according to the measurement data corresponding to the first measurement windows respectively.

In a possible design, the terminal device may further determine a first time duration according to a repetition period of the first measurement window and a maximum possible period of the synchronization signal, and the terminal device sequentially stores measurement data corresponding to each of the plurality of first measurement windows in the first time duration. For example, after the first duration is exceeded, the terminal device stops searching for the synchronization signal of the first frequency point cell, and the terminal device may switch to searching for the synchronization signal of the next frequency point cell to be tested or end searching for the synchronization signal. In addition, when the terminal device does not search the synchronization signal of the first frequency point cell within the first duration, the terminal device stops searching the synchronization signal of the first frequency point cell, and the terminal device may switch to search the synchronization signal of the next frequency point cell to be detected or end searching the synchronization signal.

In some embodiments, the first time length 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, N being a positive integer. The value of N may be determined according to the capability of the terminal device itself or the measurement requirement configured by the network device. For example, when N is 1, the first time length may be a least common multiple of a repetition period of the first measurement window and a maximum period of the synchronization signal. The maximum possible period of the synchronization signal may be determined according to a protocol specification, for example, the SSB period specified by the current protocol may be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms, as shown in table 1, and then the maximum possible period of the synchronization signal is 160 ms.

For example, the maximum possible period of the SSB specified in the current protocol is 160ms, and when the MGRP is 25ms, the terminal device determines that the number of gaps required to implement all possible positions of the SSB with the traversal period of 160ms is 32, that is, 800 ms. When the first time length is N x 800ms, in the first time length, if the terminal equipment searches for the synchronous signal of the first frequency point cell, the terminal equipment sequentially stores the measured data corresponding to the plurality of first measuring windows in the first time length, and when the first time length is exceeded, the terminal equipment finishes searching for the synchronous signal or switches to search for the synchronous signal of the next frequency point cell to be measured. And in the first time length, if the terminal equipment cannot search the synchronous signal of the first frequency point cell, the terminal equipment finishes searching or switches to search the synchronous signal of the next frequency point cell to be tested when the first time length is exceeded.

In some examples, the measurement data corresponding to the plurality of first measurement windows that are sequentially stored by the terminal device may refer to the measurement data corresponding to the plurality of first measurement windows that are sequentially stored by the terminal device within the first duration. In other examples, the terminal device may determine itself or configure the total number K of the first measurement windows through the first network device, and the terminal device may sequentially store measurement data corresponding to the K first measurement windows, where the measurement data corresponding to the plurality of first measurement windows that are sequentially stored by the terminal device at this time may refer to the measurement data corresponding to the K first measurement windows. It should be understood that, the specific form of the measurement data corresponding to each of the plurality of first measurement windows sequentially stored by the terminal device is only an example, and is not a limitation to the embodiment of the present application.

Further, for the measurement data corresponding to the plurality of first measurement windows that are sequentially stored by the terminal device, the terminal device may obtain the measurement result of the first frequency point cell by using, but not limited to, the following processing manners:

mode 1: and the terminal equipment acquires the period of the synchronous signal corresponding to the first frequency point cell. The terminal device may determine a first value according to a repetition period of the first measurement window and a period of the synchronization signal corresponding to the first frequency point cell, where the first value is the number of the first measurement windows spaced by the terminal device from two adjacent searches of the same cell. Further, the terminal device groups the measurement data corresponding to the plurality of first measurement windows according to the storage order and the first numerical value of the measurement data corresponding to the plurality of first measurement windows, so as to obtain a plurality of groups of measurement data. By adopting the method, the terminal equipment can determine which data in the stored measurement data are the positions of the same synchronous signal, and divide the measurement data into one group, namely each group of measurement data corresponds to the position of one synchronous signal. And then, the terminal equipment performs joint processing on each group of measurement data to obtain a measurement result of the first frequency point cell. The measurement result of the first frequency point cell comprises a processing result after joint processing corresponding to each group of measurement data in a plurality of groups of measurement data.

The joint processing may specifically refer to non-coherent accumulation joint detection, or other possible processing manners, which is not limited in this application.

The terminal device may determine the period of the synchronization signal corresponding to the first frequency point by using, but not limited to, the following method a and method B.

The method A comprises the following steps: since the SSB periods of the cells having the same frequency point are consistent with each other with a high probability, as long as the terminal device historically resides in any one first frequency point cell (hereinafter referred to as a first cell), the terminal device receives a system message (e.g., a System Information Block (SIB) 1) of the first cell, where the system message includes a period of a synchronization signal corresponding to the first cell. The terminal device stores the system message 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. The system message of the first cell stored by the terminal device may also be referred to as historical prior information. For example, the terminal device resides in cell1, where cell1 is a cell of frequency point 1, the terminal device stores SIB1 of cell1, and the terminal device may determine the SSB period corresponding to frequency point 1 according to the SSB period corresponding to cell1 included in SIB 1.

The method B comprises the following steps: when the terminal device searches for the synchronization signal of the second cell, the terminal device receives a system message from the second cell, wherein the system message includes a period of the synchronization signal corresponding to the second cell. The second cell is a first frequency point cell. Because the periods of the synchronization signals of the cells with the same frequency point are consistent with each other with high probability, 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 has searched for a cell at one gap, and further, the terminal device receives SIB1 of the cell, and determines the SSB period corresponding to frequency point 1 according to the SSB period corresponding to the cell included in SIB 1.

Fig. 8 shows an example of the mode 1, which is not intended to limit the present application. The terminal device determines that the SSB period corresponding to the first frequency point cell is 20ms according to the history prior information, and there are 4 possible positions of the SSBs with the period of 20ms, when MGRP is 25ms, the terminal device may search for the SSB corresponding to cell0 for the first time through the 1 st gap, may search for the SSB corresponding to cell1 for the first time through the 2 nd gap, may search for the SSB corresponding to cell2 for the first time through the 3 rd gap, may search for the SSB corresponding to cell3 for the first time through the 4 th gap, may search for the SSB corresponding to cell0 for the second time through the 5 th gap, may search for the SSB corresponding to cell1 for the second time through the 6 th gap, may search for the SSB corresponding to cell2 for the second time through the 7 th gap, and may search for the SSB corresponding to cell3 for the second time through the 8 th gap. The terminal device stores the measurement data corresponding to the 8 gaps. Further, the terminal device may determine, according to the cycle of the SSB and MGRP ═ 25ms, that the number of gap between two adjacent SSBs searching the same cell is 4, and the terminal device groups the measurement data corresponding to 8 gaps, to obtain 4 sets of measurement data, where each set of measurement data corresponds to a possible position of an SSB. Wherein, the 1 st set of measurement data includes measurement data corresponding to the 1 st gap and measurement data corresponding to the 5 th gap, i.e. the 1 st set of measurement data corresponds to the first possible position (i.e. the first 5ms) of the 4 possible positions of the SSB. The 2 nd set of measurement data includes measurement data corresponding to the 2 nd gap and measurement data corresponding to the 6 th gap, i.e., the 2 nd set of measurement data corresponds to the second possible position (i.e., the second 5ms) of the 4 possible positions of the SSB. The 3 rd set of measurement data includes the measurement data corresponding to the 3 rd gap and the measurement data corresponding to the 7 th gap, i.e., the 3 rd set of measurement data corresponds to the third possible position (i.e., the third 5ms) of the 4 possible positions of the SSB. The 4 th set of measurement data includes measurement data corresponding to the 4 th gap and measurement data corresponding to the 8 th gap, i.e., the 4 th set of measurement data corresponds to the fourth possible position (i.e., the fourth 5ms) of the 4 possible positions of the SSB. And the terminal equipment performs joint processing on the 1 st group of measurement data to obtain a processing result after the joint processing corresponding to the 1 st group of measurement data. If the cell in which the SSB is located at the first possible position (i.e., the first 5ms) of the 4 possible positions of the SSB is only one, the terminal device performs joint processing on the 1 st group of measurement data to obtain a processing result after the joint processing corresponding to the 1 st group of measurement data, where the processing result includes a measurement result corresponding to cell 0. If there are multiple cells located in the first 5ms, it is assumed that 2 cells located in the first 5ms of the SSB are 2, which are cell0 and cell4, respectively, where the signal strength of the SSB corresponding to cell0 is stronger, and the signal strength of the SSB corresponding to cell4 is weaker, so that the terminal device may only determine to measure the synchronization signal corresponding to cell0, and the terminal device may further obtain the measurement result corresponding to cell4 by performing joint processing on the 1 st set of measurement data. At this time, the processing result after the joint processing corresponding to the 1 st set of measurement data includes the measurement result corresponding to the cell0 and the measurement result corresponding to the cell 4. Through the joint processing, the terminal equipment can discover a new cell and increase the robustness of measurement.

Similarly, the terminal device may obtain a processing result after the joint processing corresponding to the 2 nd group of measurement data, a processing result after the joint processing corresponding to the 3 rd group of measurement data, and a processing result after the joint processing corresponding to the 4 th group of measurement data. And the terminal equipment takes the processing results after the joint processing corresponding to the 4 groups of measurement data as the measurement results of the first frequency point cell.

In fig. 8, the 7 th gap and the 8 th gap are not shown, and it should be understood that, here, only taking the example that the terminal device obtains 8 measurement data through the gap as an example, the terminal device may obtain more measurement data and perform the joint processing according to the more measurement data.

Mode 2: the terminal device may pre-configure the traversal order of the possible periods of the synchronization signal, or randomly generate the traversal order of the possible periods of the synchronization signal. The first synchronization signal period is assumed to be a period of a synchronization signal corresponding to the first frequency point cell, wherein the first synchronization signal period is determined according to a traversal order of possible periods of the synchronization signal. Further, the terminal device may group the measurement data corresponding to the plurality of first measurement windows stored in sequence by using the method provided in the above mode 1, to obtain a plurality of groups of measurement data, and perform joint processing on each group of measurement data. Several possible scenarios may be included at this time:

the first possible scenario: if a new cell is found by performing joint processing on any one of the 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 scenario: if no new cell is found by the joint processing of several sets of measurement data, the first synchronization signal period is erroneous. At this time, the terminal device may repeat the above process with the next possible period of the synchronization signal after the first possible period of the synchronization signal according to the traversal order of the possible periods of the synchronization signal until the synchronization signal period corresponding to the first frequency point cell and the measurement result corresponding to the first frequency point cell are determined.

For example, the terminal device searches for a cell under frequency point 1, and according to a preset SSB possible period traversal order, the terminal device first assumes that an SSB period corresponding to the cell of frequency point 1 is 20ms, and since there are 4 possible positions of SSBs with a period of 20ms, measurement data corresponding to multiple gaps sequentially stored by the terminal device are divided into 4 groups in total, where, for the 1 st group of measurement data, the terminal device does not search for a synchronization signal in the 1 st gap, and does not search for a synchronization signal in the 5 th gap, and the terminal device performs joint processing on the measurement data corresponding to the 1 st gap and the measurement data corresponding to the 5 th gap. If a new cell is found through the joint processing terminal device, it indicates that the SSB period corresponding to the cell of frequency point 1 is 20 ms.

If no new cell is found by the terminal device performing the joint processing on the 4 sets of measurement data, it is assumed that the SSB period corresponding to the cell of frequency point 1 is wrong for 20 ms. Further, the terminal device may repeat the above process according to a preset SSB possible periodic traversal order. Illustratively, when the SSB period corresponding to the cell of the frequency point 1 is assumed to be 10ms, the terminal device performs joint processing on the measurement data corresponding to the 1 st gap and the measurement data corresponding to the 3 rd gap, or when the SSB period corresponding to the cell of the frequency point 1 is assumed to be 40ms, the terminal device performs joint processing on the measurement data corresponding to the 1 st gap and the measurement data corresponding to the 9 th gap.

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

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

As shown in fig. 9, an embodiment of the present application provides a measurement method, which may be applied to a network system including a terminal device, a first network device, and a second network device. The terminal equipment is connected to the first network equipment through a first link, and the cells administered by the second network equipment comprise first frequency point cells.

The method specifically comprises the following steps:

step 910: the first network device sends the first information to the terminal device. The first information instructs the terminal equipment to measure the first frequency point cell.

It should be understood that, specific contents of step 910 may refer to the related description of step 510 in the embodiment shown in fig. 5, and repeated descriptions are omitted.

Step 920: the terminal device determines the first information.

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

It will be appreciated that the difference with the embodiment shown in figure 5 is that in the embodiment shown in figure 9 the terminal device actively adds a measurement window. Exemplarily, the network device configures a second measurement window for the terminal device, and in order to enable the terminal device to measure more first frequency point cells and/or a certain cell in the first frequency point cells, the terminal device actively adds the first measurement window. Thus, the method provided by the embodiment shown in fig. 9 can be implemented without modifying the existing protocol.

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

For example, as shown in fig. 10, when the repetition period of the second measurement window is 40ms, the terminal device cannot search for the SSB corresponding to cell2 in the second measurement window based on the repetition period of the second measurement window, and can only search for the SSB corresponding to cell1, and the terminal device may actively add the first measurement window, where the repetition period of the first measurement window is 25 ms. Wherein, the cell1 and the cell2 are cells with the same frequency point. The second measurement window is a measurement window configured for the terminal device by the network device according to the existing protocol.

In a possible design, when the terminal device determines that the number of the first frequency point cells is K1, and the number of the first frequency point cells searched by the terminal device according to the repetition period of the second measurement window is K2, the terminal device determines the first information, wherein K1 is greater than K2, K1 is greater than or equal to 1, and K2 is greater than or equal to 0.

For example, as shown in fig. 10, when the repetition period of the second measurement window is 40ms, the terminal device cannot search for the SSB corresponding to cell2 in the second measurement window based on the repetition period of the second measurement window, and can only search for the SSB corresponding to cell1, and the terminal device knows that the number of cells at the frequency point is 2, and the terminal device may actively add the first measurement window, and the repetition period of the first measurement window is 25 ms. Wherein, the cell1 and the cell2 are cells with the same frequency point. The second measurement window is a measurement window configured for the terminal device by the network device according to the existing protocol.

Step 920: and the terminal equipment searches the synchronous signal of the first frequency point cell according to the repetition period of the first measurement window.

Illustratively, as shown in fig. 9, after the terminal device adds the first measurement window, the terminal device may implement the SSB search to the cell2 based on the repetition period of the first measurement window.

Step 930: the terminal equipment sequentially stores the measurement data corresponding to the first measurement windows respectively, and obtains the measurement result of the first frequency point cell according to the measurement data corresponding to the first measurement windows respectively.

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

It should be understood that, reference may be made to the related description of step 520 to step 540 in the embodiment shown in fig. 5 for steps 920 to 940, and repeated descriptions are omitted.
