Fig. 1 illustrates an example of a communication system 100 including an adjacent access network device 101, an access network device 102, and a terminal 103, where the terminal 103 may support Dual Connectivity (DC) communication. Each access network device may manage at least one cell, as shown in fig. 1, an access network device 101 manages a cell 1, an access network device 102 manages a cell 2, and the cell 1 and the cell 2 are adjacent to each other. In the moving process of the terminal 103, the terminal 103 first enters the cell 1, accesses the access network device 101, and uses the cell 1 as a serving cell to acquire a communication service. When the terminal 103 gradually leaves the signal coverage of the cell 1 during the moving process, the terminal 103 may end the RRC connection with the cell 1, enter a non-connected state from a connected state, for example, an IDLE state (for example, RRC _ IDLE state) or an INACTIVE state (for example, RRC _ INACTIVE state), and perform cell reselection, for example, select the cell 2 as a new serving cell. The terminal entering the idle state does not retain the idle configuration information such as access stratum context configuration. The inactive state, which may also be referred to as an inactive state, is a state between an idle state and a connected state, and the terminal may retain an air interface configuration such as an access stratum context and the like in the inactive state.

The time reference point of the first cell may be obtained in a synchronization process between the terminal and an access network device that manages the first cell.

S204: and the terminal reports the measurement result of the SSB.

The terminal may store the measurement result of the SSB, and report the measurement result of the SSB to the access network device that has established the RRC connection after entering the connection state again, so that the access network device may perform operations such as fast configuration DC/CA on the terminal, or the access network device may complete functions such as mobility management and radio resource management according to the measurement result, which is not limited in this embodiment. It can be understood that the terminal in the connected state reports the latest measurement result, and 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 measurement, so as to measure the SSB without using the first measurement configuration and the time reference point of the first cell. The blind measurement may refer to the terminal performing beam scanning to obtain a corresponding SSB. In this embodiment, S202-S203 may be replaced with: and the terminal measures the SSB corresponding to the measurement frequency point in the first measurement list obtained by blind measurement.

By adopting the measurement method provided by the embodiment of the application, the terminal in the idle state or the inactive state measures the SSB corresponding to the special measurement frequency point configured for the current resident cell, and the measurement result can be used for reporting to the network side, so that the network side can timely obtain the measurement result once the terminal enters the connected state, and then the network side can perform, for example, rapid configuration of DC/CA operation for the terminal according to the measurement result, or the access network equipment completes the corresponding functions of mobility management, wireless resource management and the like according to the measurement result, thereby shortening the measurement time, improving the mobility management efficiency and improving the communication quality.

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 a new cell. The method further comprises the following steps:

s205: and the terminal reselects the cell and resides in the second cell.

The second cell and the first cell may be different cells managed by the same access network device, for example, the first access network device; or may be a different cell managed by a different access network device, for example, 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 after multiple reselections or the terminal performs cell selection to the first cell. After cell reselection, the first cell may be referred to as an original serving cell of the terminal, and the second cell may be referred to as a new camped cell of the terminal.

The terminal may measure the signal quality of one or more cells corresponding to the measurement frequency point in the cell reselection frequency point list configured in the first cell, and select the second cell as a new resident cell according to the cell reselection criterion, which is not described herein again with respect to the specific operation of cell reselection.

Optionally, in an embodiment of the present application, after camping in a second cell, the terminal may release the time reference point and the first measurement configuration of the first cell, and the terminal may measure the SSB corresponding to the measurement frequency point issued by the second cell according to a newly obtained measurement configuration (referred to as a second measurement configuration in this application) of the second cell. Specifically, the method further comprises:

s206: and the terminal receives a second frequency point list in the second cell, wherein the second frequency point list comprises the 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 system information of the second cell. The system information may be a SIB that manages access network equipment broadcast by the second cell.

S207: and the terminal acquires a second measurement configuration, wherein the second measurement configuration corresponds to the measurement frequency points in the second frequency point list.

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

Optionally, the second measurement configuration comprises a second duration, and a second periodicity. Optionally, the second measurement configuration further comprises a second offset value. The second measurement configuration may be an SMTC configuration, and for specific description of the second measurement configuration, reference may be made to the first measurement configuration, which is not described in detail.

Optionally, the second measurement configuration is included in 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. Or, the second measurement configuration is a default configuration and is not described in detail.

S208 a: and 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. The time reference point of the second cell may 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 is not described in detail herein.

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

When the terminal establishes RRC connection with the access network device managing the second cell and enters a connected state, the terminal may send the measurement result to the access network device, so that the access network device performs operations such as mobility management on the terminal.

It can be understood that after the terminal acquires 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 obtain and measure one or more corresponding SSBs according to the second measurement configuration of each frequency point; and different measurement modes can be provided for the SSBs corresponding to other measurement frequency points which 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 measure the SSB corresponding to the measurement frequency point according to the second measurement configuration corresponding to the measurement frequency point in the second frequency point list, in combination with the time reference point of the second cell.

For another example, when at least one measurement frequency point in the second frequency point list is different from the first frequency point list, SSBs corresponding to at least one measurement frequency point (exemplified by frequency point a) appearing in the two frequency point lists at the same time, at least one measurement frequency point (exemplified by frequency point B) appearing in the first frequency point list only and not appearing in the second frequency point list, and at least one measurement frequency point (exemplified by frequency point C) appearing in the second frequency point list only and not appearing in the first frequency point list respectively may be measured in the following different manners:

S208 b: and the terminal measures the SSB corresponding to the first frequency point by adopting the second measurement configuration corresponding to the frequency point A and the time reference point of the second cell.

S208 c: and the terminal measures the SSB corresponding to the frequency point B by adopting default configuration and 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 SSBs corresponding to the measurement frequency points that are only contained in the first frequency point list and not contained in the second frequency point list, the terminal may use a default configuration for measurement. Optionally, the terminal may also obtain the SSB corresponding to the second frequency point through blind detection, so as to perform measurement.

S208 d: and the terminal measures the SSB corresponding to the third frequency point by adopting the second measurement configuration corresponding to the frequency point C and the time reference point of the second cell.

It is to be appreciated that any one or combination of S208b-S208d, as described above, may be substituted for step S208 a.

The number of the frequency point a, the frequency point B, and the frequency point C may be one or more, respectively, and is not limited.

Optionally, in an embodiment of the present application, the terminal may obtain, through blind inspection, a time domain position of the SSB corresponding to the measurement frequency point in the second frequency point list, so as to perform measurement, without obtaining the second measurement configuration, that is, S207 may not be executed. And 209 can be replaced by: and the terminal measures at least one SSB which 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 perform measurement using a default configuration.

In the above embodiment, the terminal may release the measurement configuration and the time reference point of the original serving cell after the cell reselection, and measure the SSB using the measurement configuration or the default configuration of the newly camped cell and the time reference point, so that the terminal overhead is saved and the measurement result is accurate.

Fig. 3 is a schematic flowchart of a measurement method provided in the present application. In this embodiment, considering that the duration parameter and the period parameter included in the measurement configuration such as the SMTC configuration may be constant variables, after the terminal performs cell reselection, the terminal may continue to use the first frequency point list acquired from the original serving cell (e.g., the first cell described above), and the duration and the period in the first measurement configuration, and obtain the offset through calculation. The method comprises the following steps:

s301: the method comprises the steps that a terminal receives a first message in a first cell, wherein the first message is used for indicating the terminal to release connection with the first cell, the first message comprises a first frequency point list, and the first frequency point list comprises measuring frequency points.

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

The first measurement configuration may include a first duration, a first period, and a first offset value, which is not described in detail.

For S301 to S302, reference may be made to the descriptions of S201 to S202, which are not described in detail.

It can be understood that the terminal may still camp in the first cell before performing cell reselection, and measure the SSB corresponding to the measurement frequency configured in the first cell, and store the measurement result for reporting, for example, to perform operations such as S204-S205, which is not illustrated here.

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

S304: and the terminal reselects the cell and resides in the second cell.

In particular, after camping on the second cell, the terminal may not release the first duration and the first period in the first measurement configuration, i.e. the terminal continues to store both parameters. Furthermore, the terminal may release other parameters in the first measurement configuration, such as the first offset value, etc. Wherein, the first period may adopt a system default parameter, for example, 5 ms; the first duration may be a 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: and the terminal acquires a time reference point of the second cell.

The terminal may obtain the time reference point of the second cell in the synchronization process with the access network device managing the second cell, which is not described in detail herein.

S306: and the terminal performs blind test on the SSB corresponding to the measurement frequency point in the first frequency point list to obtain a bias value in the measurement configuration.

In one implementation manner, the terminal obtains one SSB corresponding to the measurement frequency point through beam scanning, for example, the SSB appearing first at the frequency point, and then obtains the initial time domain position t1 of the SSB according to the time reference point of the second cell, and further obtains the offset value | t1-t2| according to the position t2 of the frame boundary.

S307: and 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 bias 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. And then, the terminal measures one or more SSBs corresponding to the measurement frequency point by adopting the complete measurement configuration.

When one measurement frequency point in the second frequency point list corresponds to multiple SSBs, because the multiple SSBs appear periodically, the terminal may use the first measurement configuration and the bias value to measure other SSBs besides the SSBs obtained by the blind detection, including determining positions of the other SSBs, and measuring signal strengths of the other SSBs.

Optionally, in an embodiment of the present application, the terminal may only maintain the first duration, and obtain the offset value and the duration through blind detection of the SSB, thereby obtaining a complete measurement configuration and measuring the SSB, which is not described in detail herein.

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, and in this embodiment, the steps S303 to S307 may be replaced by S303 'to S305', including:

s303': the terminal maintains a time reference point of the first cell and the first measurement configuration.

Specifically, after the terminal camps on the second cell, the time reference point and the first measurement configuration of the first cell may be stored without releasing.

And S304': and the terminal reselects the cell and resides in a second cell.

S305': and 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 acquire the measurement configuration corresponding to the measurement frequency point configured in the second cell, or acquire the measurement configuration but does not use it, which is not limited.

In the embodiment, after the cell is reselected, the terminal continuously uses the measurement configuration and the frequency point list of the original serving cell, so that the signaling overhead is low, and the complexity of the measurement process is reduced.

Optionally, in an embodiment of the present application, the terminal may reselect back to the first cell through multiple times of cell reselection or return to the first cell through cell selection, that is, the terminal re-camps on the first cell, and further re-measures the corresponding SSB by using the stored first frequency point list and the first measurement configuration, which is not described in detail herein.

Fig. 4 is a schematic flowchart of a measurement method according to an embodiment of the present application. In this embodiment, the terminal reselects from the first cell to the second cell, and the terminal only obtains the frequency point list (such as the above first frequency point list) in the first cell, and does not obtain the measurement configuration (such as the above first measurement configuration) related to the first cell from the message sent by the network side.

The method comprises the following steps:

s401: the method comprises the steps that a terminal receives a first message in a first cell, wherein the first message is used for indicating the terminal to release connection with the first cell, the first message comprises a first frequency point list, and the first frequency point list comprises measuring frequency points.

For a detailed description of S401, reference may be made to S201, which is not described in detail.

S402: and the terminal reselects the cell and resides in the second cell.

The terminal may obtain the time reference point of the second cell in the synchronization process with the second cell, which is not described in detail.

S403: and the terminal receives a second frequency point list in the second cell, wherein the second frequency point list comprises the measurement frequency points.

S404: and the terminal acquires at least one second measurement configuration, wherein the second measurement configuration corresponds to the measurement frequency points in the second frequency point list.

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

For specific description of S402-S404, reference may be made to S205-S207, which is not described in detail.

It is understood that the terminal may release the time reference point of the first cell after the terminal reselects to the second cell.

S405: and the terminal respectively measures the SSBs 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 may measure the SSB corresponding to the measurement frequency point according to a 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. When at least one measuring frequency point in the first frequency point list and the second frequency point list is different, the terminal can adopt a second measuring configuration sent by the network side to measure the SSB corresponding to the measuring frequency point simultaneously appearing in the two frequency point lists in combination with the time reference point of the second cell; and the SSBs corresponding to the measurement frequency points which only appear in the first frequency point list and do not appear in the second frequency point list can be measured by adopting default configuration or can be stopped to be measured. For a detailed description of S405, reference may be made to S208a-S208d, which are not described in detail.

Optionally, in an embodiment of the present application, if the network side does not issue the second measurement configuration through the system information, the terminal may use a default configuration to measure at least one SSB corresponding to each of the first frequency point list and/or the second frequency point list. Alternatively, the terminal may obtain the SSB through blind measurement and perform measurement, or the terminal device may also stop measurement, which is not described in detail.

In this embodiment, even if the terminal does not obtain the measurement configuration from the original serving cell, the terminal may still measure the SSB corresponding to the measurement frequency configured in the original serving cell, thereby improving the accuracy of the measurement result.

Fig. 5 is a signaling flow diagram of a measurement method according to an embodiment of the present application. In this embodiment, the first cell belongs to the gNB1, and the second cell belongs to the gNB2, but the first cell and the second cell may also belong to the same access network device, which is only an example. The terminal firstly establishes RRC connection with the gNB1, uses the first cell as a serving cell, and then performs cell reselection, and uses the second cell under the gNB2 as a new camping cell. It can be understood that the embodiment shown in fig. 5 is based on the embodiments shown in fig. 2 to fig. 4, and further explanation and explanation of the measurement method provided in the present application are provided, and the contents already introduced before will not be described again.

S500: the terminal acquires a time reference point of the first cell.

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

S501: the 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. Or, the RRC connection release message does not include the first frequency point list, and the terminal obtains the first frequency point list by reading the system information of the first cell.

Optionally, the RRC connection release message may further include a first measurement configuration corresponding to a measurement frequency point in the first frequency point list. Alternatively, the first measurement configuration may also be included in 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 indication of the gNB1, disconnects the RRC connection with the first cell, thereby entering an idle state or an inactive state.

It is to be appreciated that the terminal may still camp on the first cell when the terminal is not performing cell reselection. The terminal may perform operations such as performing early measurement on the SSB corresponding to the measurement frequency point configured by the gNB1 for the first cell, for example, refer to the description of S204 to S205, which is not described in detail.

S503: the terminal reselects to the second cell under the gNB 2.

Specifically, the terminal completes a cell reselection process, and takes the second cell as a new camping cell.

S504: the terminal acquires a time reference point of the second cell.

S505: the gNB2 broadcasts system information.

Correspondingly, the terminal receives the system information, wherein the system information comprises a second frequency point list of a second cell. Optionally, the system information further includes a second measurement configuration corresponding to the measurement frequency point in the second frequency point list.

S506: the terminal performs early measurements in the second cell.

S507: the terminal sends the early measurement results to the gNB 2.

Specifically, after the terminal establishes RRC connection with the gNB2, the measurement result is sent to the gNB 2.

The gNB2 may determine whether to perform operations such as fast configuration DC/CA for the terminal based on the early measurement results.

In this embodiment, the procedure of performing early measurement in the second cell by the terminal is described by taking the first frequency point list as { f1, f2} and the second frequency point list as { f1, f3 }. Wherein f1, f2 and f3 represent different 3 special 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 }. Assuming 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 and f2} correspond to first cells respectively, and { configuration 1-1 and configuration 1-2} and { f1 and f3} correspond to second cells respectively, and second measurement configuration { configuration 2-1 and configuration 2-3 }. Each measurement configuration may be used to determine the SSB of the measurement frequency point corresponding to the measurement configuration in the corresponding cell, for example, configuration 1-1 may be used to locate the SSB1 of f1 in the first cell, which is not described in detail. Further, the terminal may store a default configuration for early measurements. It can be understood that the number of SSBs corresponding to one measurement frequency point is not limited in the present application.

Depending on the conditions, such as whether the terminal obtained the first measurement configuration from the gNB1 or the second measurement configuration from the gNB2, respectively, the early measurement performed by the terminal in the second cell may be performed in a variety of manners, for example:

in the mode 1, the terminal receives { configuration 2-1, configuration 2-3} from the system information broadcast by the gNB2 in the second cell, and then the terminal may measure, by using configuration 2-1, the SSB1-1 and the SSB1-2 corresponding to f1, respectively in combination with the time reference point of the second cell; configuration 2-3 was used to measure SSB3-1 and SSB3-2 for f 3. In addition, the terminal may use a default configuration to measure SSB2-1 and/or SSB2-2 corresponding to f2 in conjunction with the time reference point of the second cell, or the terminal may not measure SSB2-1 and/or SSB2-2, or the terminal may directly blindly measure and make measurements of SSB2-1 and/or SSB 2-2.

In the method 2 and the gNB2, the system information broadcasted by the second cell does not include { configuration 2-1, configuration 2-2}, and the terminal may adopt default configuration and combine with the time reference point of the second cell to measure each SSB corresponding to f1-f3, which is not described in detail.

The detailed description of the modes 1-2 can refer to the related contents in the embodiment shown in fig. 2, for example, steps S208a-S208d, which are not repeated.

In the mode 3, the terminal acquires { configuration 1-1, configuration 1-2} from the first cell, and the broadcast message of the gNB2 does not include { configuration 2-1, configuration 2-3}, the terminal may maintain the duration and the period parameter in configuration 1-1 and configuration 1-2 received from the gNB, respectively, and further, the terminal may blindly measure the SSB1-1 and the SSB2-1 according to the time reference point of the second cell and calculate the offset value respectively, and then obtain the complete measurement configuration corresponding to f1, f2, and f3 according to the maintained duration and period parameter and the calculated offset value. Then, the terminal may use the full-configuration measurement SSB1-2 corresponding to f1 and the full-configuration measurement SSB2-2 corresponding to f2 respectively in conjunction with the time reference point of the second cell. In addition, the terminal may use a default configuration to measure SSB3-1 and/or SSB3-2 in conjunction 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 blindly measure and measure SSB3-1 and/or SSB3-2 directly.

The detailed description of the method 3 may refer to the relevant contents in the embodiment shown in fig. 3, for example, steps S306 to S307, which are not described in detail.

In the method 4, the terminal does not acquire { configuration 1-1, configuration 1-2} from the first cell, and the terminal acquires { configuration 1-1, configuration 1-3} from the system information broadcast by the gNB2 in the second cell, then the terminal may measure, by using configuration 1-1, SSB1-1 and SSB1-2 corresponding to f1, using configuration 1-3, SSB3-1 and SSB3-2 corresponding to f3, and using a default configuration to measure or not measure SSB2-1 and/or SSB2-2 corresponding to f2, respectively, in combination with the time reference point of the second cell.

For the detailed description of the mode 4, reference may be made to related contents in the embodiment shown in fig. 4, for example, step S405, which is not described in detail.

In the modes 1 to 4, the terminal may release the time reference point of the first cell.

Mode 5, the terminal acquires { configuration 1-1, configuration 1-2} from the RRC connection release message sent by the gNB1, and the terminal may not release the time reference point of the first cell, and then the terminal may use configuration 1-1 to measure SSB1-1 and SSB1-2 corresponding to f1, respectively, in combination with the time reference point of the first cell; configuration 1-2 was used to measure SSB2-1 and SSB2-2 for f 2. In addition, if the terminal also receives configuration 2-3 from the broadcast message of the gNB2, the terminal may measure SSB3-1 and/or SSB3-2 corresponding to f3 with configuration 2-3 in conjunction with the time reference point of the second cell; if the configuration 2-3 is not included in the system information broadcast by the gNB2, the terminal may use a default configuration in combination with the time reference point of the second cell to measure SSB3-1 and/or SSB3-2, or the terminal may not measure SSB3-1 and/or SSB3-2, or the terminal may directly blindly measure and obtain SSB3-1 and/or SSB 3-2.

The detailed description of the method 5 can refer to the related contents in the embodiment shown in fig. 3, for example, steps S304 '-S305', which are not described in detail.

It can be understood that, in the present application, the early measurement modes executed by the terminal on different measurement frequency points (for example, the measurement frequency point carried in the RRC connection release message, the measurement frequency point of the system information broadcast of the original serving cell, or the measurement frequency point of the system information broadcast of the newly camped cell) may have various combination modes, and the above modes 1 to 5 are only examples and do not constitute any limitation.

By adopting the measurement method provided by the embodiment of the application, no matter how the measurement configuration obtained by the terminal before and after cell reselection changes, the terminal can carry out early measurement according to the appropriate measurement configuration, so that the robustness of the measurement behavior and the accuracy of the measurement result are improved.
