The terminal may store the measurement result of the SSB, and after re-entering the connected state, report the measurement result of the SSB to the access network device that has established an RRC connection for the access network device to perform, for example, quick configuration DC on the terminal Operations such as /CA, or the access network device completes corresponding mobility management, radio resource management and other functions according to the measurement results, which are not limited in this embodiment. It can be understood that the terminal in the connected state reports the latest measurement result. Specifically, if the terminal performs multiple measurements in the unconnected state, the terminal reports the last measurement result in the unconnected state after entering the connected state.

Optionally, in an embodiment of the present application, the terminal may directly obtain the time window for measuring the SSB through blind testing, so as to measure the SSB without using the first measurement configuration and the time reference point of the first cell. Among them, the blind test may refer to the terminal performing beam scanning to obtain the corresponding SSB. In this embodiment, S202-S203 can be replaced by: the terminal measures the SSB corresponding to the measurement frequency point in the first measurement list obtained by the blind test.

Using the measurement method provided in the embodiments of this application, a terminal entering the idle state or inactive state measures the SSB corresponding to the dedicated measurement frequency point configured in the current camping cell, and the measurement result can be used to report to the network side, so that the terminal In the connected state, the network side can obtain the measurement results in time, and then the network side can perform, for example, fast configuration DC/CA operations for the terminal based on the measurement results, or the access network equipment can complete corresponding mobility management, radio resource management and other functions based on the measurement results , Thereby shortening the measurement time, improving the efficiency of mobility management, and improving the quality of communication.

Optionally, in an embodiment of the present application, after the terminal enters an idle state or an inactive state, cell reselection may be performed, and measurement may be performed in the newly camped cell. The method also includes:

S205: The terminal performs cell reselection and camps on the second cell.

The second cell and the first cell may be different cells managed by the same access network device, for example, the aforementioned first access network device; or they may be different cells managed by different access network devices, such as the The second cell is managed by a second access network device, and the second access network device is adjacent to the first access network device. Optionally, the first cell and the second cell may also be the same cell, that is, the terminal returns to the first cell or the terminal selects the first cell after multiple reselections. After cell reselection is performed, the first cell may be referred to as the original serving cell of the terminal, and the second cell may be referred to as the new camping cell of the terminal.

The terminal can measure the signal quality of one or more cells corresponding to the measurement frequency points in the cell reselection frequency list configured in the first cell, and select the second cell as the new camping cell according to the cell reselection criteria. Regarding cell reselection The specific operation of this application will not go into details.

Optionally, in an embodiment of the present application, after the terminal camps on the second cell, it can release the time reference point and the first measurement configuration of the first cell, and the terminal can release the time reference point and the first measurement configuration of the first cell according to the newly acquired second cell. The measurement configuration of the cell (referred to as the second measurement configuration in this application) is used to measure the SSB corresponding to the measurement frequency issued by the second cell. Specifically, the method further includes:

S206: The terminal receives a second frequency point list in the second cell, where the second frequency point list includes measurement frequency points.

The second frequency point list may include one or more measurement frequency points, and each measurement frequency point may correspond to one or more SSBs.

Optionally, the second frequency point list is included in the system information of the second cell. The system information may be an SIB broadcast by an access network device that manages the second cell.

S207: The terminal acquires a second measurement configuration, where the second measurement configuration corresponds to a measurement frequency point in the second frequency point list.

The second frequency point list may be a frequency point list configured for early measurement, including at least one dedicated measurement frequency point for early measurement; or may be a frequency point list configured for cell reselection, including at least one dedicated frequency point for cell reselection. The measurement frequency is not limited.

Optionally, the second measurement configuration includes a second duration and a second period. Optionally, the second measurement configuration further includes a second offset value. The second measurement configuration may be an SMTC configuration. For a specific description of the second measurement configuration, reference may be made to the foregoing first measurement configuration, and details are not repeated.

Optionally, the second measurement configuration is included in the system information of the second cell, for example, the second measurement configuration and the second frequency point list are issued through the same system information. Alternatively, the second measurement configuration is a default configuration, and will not be described in detail.

S208a: The terminal measures the SSB corresponding to the measurement frequency point in the second frequency point list according to the second measurement configuration.

Optionally, the terminal may measure one or more SSBs corresponding to the second measurement configuration according to the second measurement configuration and the time reference point of the second cell. Wherein, the time reference point of the second cell can be used to calculate the initial time domain position of the SSB to be measured in combination with the offset value of the second cell, which will not be repeated.

Optionally, the method further includes S209: the terminal sends the measurement result to the access network device that manages the second cell.

When the terminal establishes an RRC connection with the access network device that manages the second cell and enters the connected state, the measurement result can be sent to the access network device, so that the access network device can perform operations such as mobility management on the terminal.

It can be understood that, after the terminal obtains one or more measurement frequency points belonging to the second frequency point list and the second measurement configuration corresponding to each measurement frequency point from the second cell, the terminal may perform the second measurement configuration according to each frequency point Obtain the corresponding one or more SSBs and perform measurement; there may be different measurement methods for SSBs corresponding to other measurement frequency points that do not appear in the second frequency point list.

For example, when the second frequency point list is the same as the first frequency point list, that is, each measurement frequency point in the two frequency point lists is the same, the terminal may use the measurement frequency point in the second frequency point list The corresponding second measurement configuration is combined with the time reference point of the second cell to measure the SSB corresponding to the measurement frequency point.

For another example, when at least one measurement frequency point in the second frequency point list is different from the first frequency point list, for at least one measurement frequency point appearing in the two frequency point lists at the same time (with the frequency point A example), at least one measurement frequency point that only appears in the first frequency point list and does not appear in the second frequency point list (take frequency point B for example), and only appears in the second frequency point list and does not appear The SSB corresponding to at least one measurement frequency point (take frequency point C as an example) in the first frequency point list can use the following different measurement methods:

S208b: The terminal uses the second measurement configuration corresponding to frequency point A and the time reference point of the second cell to measure the SSB corresponding to the first frequency point.

S208c: The terminal uses the default configuration to measure the SSB corresponding to frequency point B with the time reference point of the second cell.

In S208c, if the terminal has released the first measurement configuration, if the terminal still wants to measure the SSB corresponding to the measurement frequency points that are only included in the first frequency point list and not included in the second frequency point list, the terminal can Use the default configuration for measurement. Optionally, the terminal may also obtain the SSB corresponding to the second frequency point through blind detection to perform measurement.

S208d: The terminal uses the second measurement configuration corresponding to frequency C and the time reference point of the second cell to measure the SSB corresponding to the third frequency.

It can be understood that any one or a combination of the above S208b-S208d can replace step S208a.

Wherein, the number of frequency point A, frequency point B, and frequency point C may be one or more, respectively, which is not limited.

Optionally, in an embodiment of the present application, the terminal may obtain the time domain position of the SSB corresponding to the measurement frequency point in the second frequency point list through blind detection to perform measurement without obtaining the second measurement configuration, that is, S207 Can not be implemented. And 209 may be replaced by: the terminal performs measurement on at least one SSB that is blindly detected by the cell under the second frequency point list.

Optionally, in an embodiment of the present application, when the second message does not include the second measurement configuration, the terminal may terminate the measurement operation or use the default configuration to perform measurement.

In the above embodiment, the terminal can release the measurement configuration and time reference point of the original serving cell after the cell reselection, and use the measurement configuration or default configuration and time reference point of the new camping cell to measure the SSB, which saves terminal overhead and measurement The result is accurate.

Fig. 3 is a schematic flowchart of a measurement method provided by the present application. In this embodiment, considering that the duration parameter and period parameter contained in the measurement configuration such as the SMTC configuration may be constant variables, after the terminal performs cell reselection, the terminal can continue to use the original serving cell (for example, the first cell ) The obtained first frequency point list, and the duration and period in the first measurement configuration, and the offset is obtained through calculation. The method includes:

S301: The terminal receives a first message in the first cell, the first message is used to instruct the terminal to release the connection with the first cell, the first message includes a first frequency list, and the first frequency list includes Measurement frequency point.

S302: The terminal acquires a first measurement configuration, where the first measurement configuration corresponds to a measurement frequency point in the first frequency point list.

Wherein, the first measurement configuration may include a first duration, a first period, and a first offset value, which will not be repeated.

For S301-S302, please refer to the description of S201-S202, which will not be repeated.

It can be understood that the terminal can still stay in the first cell before performing cell reselection, measure the SSB corresponding to the measurement frequency point configured in the first cell, and store the measurement result for reporting, for example, perform operations such as S204-S205 , Not shown here.

S303: The terminal maintains the first duration and the first period in the first measurement configuration.

S304: The terminal performs cell reselection and camps on the second cell.

Specifically, after camping on the second cell, the terminal may not release the first duration and the first period in the first measurement configuration, that is, the terminal continues to store these two parameters. In addition, the terminal may release other parameters in the first measurement configuration, such as the first offset value. The first period may adopt a system default parameter, such as 5 ms; the first duration may be the duration of the SSB corresponding to the measurement frequency point corresponding to the first measurement configuration.

In addition, the terminal may release the time reference point of the first cell.

S305: The terminal obtains the time reference point of the second cell.

The terminal may obtain the time reference point of the second cell during the synchronization process with the access network device that manages the second cell, which is not repeated here.

S306: The terminal obtains the offset value in the measurement configuration by performing a blind test on the SSB corresponding to the measurement frequency point in the first frequency point list.

In an implementation manner, the terminal obtains an SSB corresponding to the measurement frequency point through beam scanning, for example, the SSB that appears first under the frequency point, and then obtains the start time domain of the SSB according to the time reference point of the second cell The position t1, and then according to the position t2 of the frame boundary, the offset value is obtained |t1-t2|.

S307: The terminal measures the SSB corresponding to the measurement frequency point in the first frequency point list according to the first measurement configuration and the offset value.

In other words, according to the calculated offset value and the three parameters of the first period and the first duration maintained by the terminal, the terminal can obtain a complete measurement configuration corresponding to any measurement frequency point in the first measurement list. Furthermore, the terminal uses the complete measurement configuration to measure one or more SSBs corresponding to the measurement frequency point.

When a measurement frequency point in the second frequency point list corresponds to multiple SSBs, since multiple SSBs appear periodically, the terminal can use the first measurement configuration and the offset value to measure the SSB obtained by blind detection The other SSBs, including determining the location of other SSBs, and measuring the signal strength of other SSBs.

Optionally, in an embodiment of the present application, the terminal may only maintain the first duration, and calculate the offset value and duration through blind detection of the SSB, so as to obtain a complete measurement configuration and measure the SSB. Do repeat.

Optionally, in an embodiment of the present application, after camping on the second cell, the terminal may also maintain the time reference point of the first cell and the complete first measurement configuration. In this embodiment, step S303- S307 can be replaced by S303'-S305', including:

S303': The terminal maintains the time reference point and the first measurement configuration of the first cell.

Specifically, after the terminal camps on the second cell, it may continue to store the time reference point and the first measurement configuration of the first cell without releasing it.

S304': The terminal performs cell reselection and camps on the second cell.

S305': The terminal measures the SSB corresponding to the measurement frequency point in the first frequency point list according to the first measurement configuration and the time reference point of the first cell.

It can be understood that, in this embodiment, the terminal may not obtain the measurement configuration corresponding to the measurement frequency point configured in the second cell, or obtain the measurement configuration but not use it, which is not limited.

In this embodiment, after the cell reselection, the terminal continues to use the measurement configuration and frequency list of the original serving cell, which reduces signaling overhead and reduces the complexity of the measurement process.

Optionally, in an embodiment of the present application, the terminal may return to the first cell after multiple cell reselections or return to the first cell through cell selection, that is, the terminal camps on the first cell again, and then uses the stored The first frequency point list and the first measurement configuration measure the corresponding SSB again, which will not be repeated.

In this embodiment, the terminal reselects from the first cell to the second cell, and the terminal only obtains the frequency list in the first cell (such as the above-mentioned first frequency list), and does not obtain it from the message sent by the network side The measurement configuration related to the first cell (such as the above-mentioned first measurement configuration).

The method includes:

S401: The terminal receives a first message in the first cell, the first message is used to instruct the terminal to release the connection with the first cell, the first message includes a first frequency list, and the first frequency list includes Measurement frequency point.

Wherein, the second measurement configuration may be issued by the network side through system information, or may be a default configuration.

For the specific description of S402-S404, please refer to S205-S207, which will not be repeated.

It can be understood that after the terminal reselects to the second cell, the terminal can release the time reference point of the first cell.

S405: The terminal separately measures the SSB corresponding to the measurement frequency points in the first frequency point list and/or the second frequency point list according to the time reference point of the second cell and the second measurement configuration.

When the first frequency point list is the same as the second frequency point list, the terminal can determine the measurement frequency point according to the second measurement configuration corresponding to the measurement frequency point in the first frequency point list in combination with the time reference point of the second cell. The corresponding SSB is measured. When at least one measurement frequency point is different in the first frequency point list and the second frequency point list, for the SSB corresponding to the measurement frequency points that appear in the two frequency point lists at the same time, the terminal can use the one issued by the network side The second measurement configuration is combined with the time reference point of the second cell for measurement; the SSB corresponding to the measurement frequency point that only appears in the first frequency point list and does not appear in the second frequency point list can be measured using the default configuration or can Stop the measurement. For a detailed description of S405, refer to S208a-S208d, which will not be repeated.

Fig. 5 is a schematic diagram of the signaling flow of the measurement method provided by an embodiment of the present application. In this embodiment, it is described that the first cell belongs to gNB1 and the second cell belongs to gNB2. The first cell and the second cell may also belong to the same access network device, which is only an example here. The terminal first establishes an RRC connection with gNB1, and uses the first cell as the serving cell, and then the terminal performs cell reselection, and uses the second cell under gNB2 as the new camping cell. It can be understood that the embodiment shown in FIG. 5 is a further explanation and description of the measurement method provided in the present application on the basis of the embodiment shown in FIGS. 2 to 4, and the content that has been introduced before will not be repeated.

S500: The terminal obtains the time reference point of the first cell.

The time reference point of the first cell is used to determine the start time domain position of the time window of the SSB corresponding to the measurement frequency point configured for the first cell by gNB1.

S501: gNB1 sends an RRC connection release message to the terminal through the first cell.

Optionally, the RRC connection release message includes a first frequency point list. Alternatively, the RRC connection release message does not include the first frequency list, and the terminal obtains the first frequency list by reading the system information of the first cell.

S502: The terminal disconnects the RRC connection with the first cell.

Specifically, the terminal receives the RRC connection release message, and according to the instruction of gNB1, disconnects the RRC connection with the first cell, thereby entering an idle state or an inactive state.

It can be understood that before the terminal performs cell reselection, the terminal can still camp in the first cell. The terminal may perform operations such as early measurement of the SSB corresponding to the measurement frequency point configured by the gNB1 for the first cell, for example, refer to the description of S204-S205, which will not be repeated.

In this embodiment, the first frequency list is {f1, f2} and the second frequency list is {f1, f3} as an example to illustrate the process of the terminal performing early measurement in the second cell. Among them, f1, f2, f3 represent three different dedicated measurement frequency points. The intersection of the first frequency point list and the second frequency point list is {f1}, and the union of the first frequency point list and the second frequency point list is {f1, f2, f3}. Assume that f1, f2, and f3 correspond to SSB1-1 and SSB1-2, f2 corresponds to SSB2-1 and SSB2-2, f3 corresponds to SSB3-1 and SSB3-2, and {f1, f2} corresponds to the first cell of the first cell. The measurement configuration is {configuration 1-1, configuration 1-2}, and the second measurement configuration of the second cell corresponding to {f1, f3} is {configuration 2-1, configuration 2-3}. Among them, each measurement configuration can be used to determine the SSB of the measurement frequency corresponding to the measurement configuration in the corresponding cell. For example, the configuration 1-1 can be used to locate the SSB1 of f1 in the first cell, which will not be repeated. In addition, the terminal can store a default configuration for early measurement. It can be understood that this application does not limit the number of SSBs corresponding to one measurement frequency point.

According to whether the terminal obtains the above-mentioned first measurement configuration from gNB1 or the above-mentioned second measurement configuration from gNB2 and other conditions respectively, the early measurement performed by the terminal in the second cell can have multiple operation modes, for example:

Method 1. When the terminal receives {configuration 2-1, configuration 2-3} from the system information broadcast by gNB2 in the second cell, the terminal can combine the time reference point of the second cell and use configuration 2-1 to measure the corresponding f1 SSB1-1 and SSB1-2; use configuration 2-3 to measure SSB3-1 and SSB3-2 corresponding to f3. In addition, the terminal can use the default configuration to measure the SSB2-1 and/or SSB2-2 corresponding to f2 in combination with the time reference point of the second cell, or the terminal can not measure SSB2-1 and/or SSB2-2, or the terminal can directly perform blind measurement Obtain and measure SSB2-1 and/or SSB2-2.

Method 2. gNB2 does not include {Configuration 2-1, Configuration 2-2} in the system information broadcast by the second cell, and the terminal can use the default configuration and the time reference point of the second cell to measure each SSB corresponding to f1-f3. , Do not repeat it.

According to the maintained duration and period parameters and the calculated offset value, the complete measurement configuration corresponding to f1, f2, and f3 is obtained. Then, the terminal can respectively combine the time reference point of the second cell to measure SSB1-2 with the complete configuration corresponding to f1 and to measure SSB2-2 with the complete configuration corresponding to f2. In addition, the terminal may use the default configuration to measure SSB3-1 and/or SSB3-2 in combination with the time reference point of the second cell, or the terminal may not measure SSB3-1 and/or SSB3-2, or the terminal may directly blindly measure SSB3- 1 and/or SSB3-2 and measure.

For a detailed description of mode 3, reference may be made to related content in the embodiment shown in FIG. 3, such as steps S306-S307, which are not repeated here.

Method 4: The terminal does not obtain {configuration 1-1, configuration 1-2} from the first cell, and the terminal obtains {configuration 1-1, configuration 1-3} from the system information broadcast by gNB2 in the second cell, then The terminal can use configuration 1-1 to measure SSB1-1 and SSB1-2 corresponding to f1 in combination with the time reference point of the second cell, use configuration 1-3 to measure SSB3-1 and SSB3-2 corresponding to f3, and use the default configuration to measure Or not measure the SSB2-1 and/or SSB2-2 corresponding to f2.

Manner 5. The terminal obtains {configuration 1-1, configuration 1-2} from the RRC connection release message sent by gNB1. The terminal may not release the time reference point of the first cell, and the terminal may combine the time reference of the first cell separately Point, use configuration 1-1 to measure SSB1-1 and SSB1-2 corresponding to f1; use configuration 1-2 to measure SSB2-1 and SSB2-2 corresponding to f2. In addition, if the terminal also receives configuration 2-3 from the broadcast message of gNB2, the terminal can use configuration 2-3 to measure the SSB3-1 and/or SSB3-2 corresponding to f3 in conjunction with the time reference point of the second cell; if gNB2 broadcasts If the system information does not contain configuration 2-3, the terminal can use the default configuration to measure SSB3-1 and/or SSB3-2 in combination with the time reference point of the second cell, or the terminal may not measure SSB3-1 and/or SSB3-2 , Or the terminal can directly obtain SSB3-1 and/or SSB3-2 through blind measurement and perform measurement.
