Description

Configuration and use method, equipment and device of synchronization signal block measurement configuration

This application claims priority from a chinese patent application entitled "configuration of a synchronization signal block measurement time configuration, method of use, apparatus, and device" filed by the chinese patent office on 15/8/2019 with application number 201910755394.4, the entire contents of which are incorporated herein by reference.

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, a device, and an apparatus for configuring and using a synchronization signal block measurement configuration.

Background

The SMTC (synchronization signal Block Measurement Time Configuration) will be described first.

NR (New Radio) RRM (Radio Resource Management) measures a measurement object currently supporting two kinds of pilots, including SSB (Synchronization Signal Block) and CSI-RS (Channel state information Reference Signal). In NR, each cell transmits a set of SSB blocks with a configured periodicity and pattern. In order to inform the UE (User Equipment) of the specific moment to search for and measure the SSB, the network may configure the UE with an SSB block RRM measurement timing configuration SMTC. The SMTC configuration comprises:

-measurement window period (Periodicity), which may take {5,10,20,40,80,160} ms;

-a time offset (offset) within a period,

and a measurement window duration {1, 2...., 5} ms.

The time when each SMTC occurs is based on NR SpCell (Special Cell) or the time when the Cell currently resides, and the corresponding SFN (system frame number) and the first subframe (subframe) of the SFN occur are calculated as follows:

SFN mod T＝(FLOOR(Offset/10))；

if the period is greater than 5ms, subframe is Offset mod 10; otherwise subframe is Offset or (Offset + 5);

wherein T ═ CEIL (Periodicity/10).

The network side configures an SMTC for each SSB-based measurement object. For the SSB measurement of the same frequency, an SMTC with a smaller period may be additionally configured for some cells, so as to obtain the measurement result of the corresponding cell more quickly.

The defects of the prior art are as follows:

the SMTC is based on the time of the current camped cell (for non-connected state) or the special serving cell (for connected state). In actual deployment, some cells are completely synchronized in time; some cells are not synchronized in time and there is a time difference. If the UE receives the SMTC configured by the network side, and then changes a (special) serving cell, how to determine the SMTC corresponding to the SSB measurement is not currently available.

Detailed Description

The inventor notices in the process of invention that:

when measuring SSB in NR, the network side will inform UE to search and measure the time window SMTC of SSB. But the configuration is based on the time of the current camped cell (for non-connected state) or the special serving cell (for connected state). If the UE receives the SMTC configured by the network side, and then changes a (special) serving cell, how to determine the corresponding SMTC measured by the SSB is not currently available.

Further, the inventors have also noted that:

the SSB measurement configuration may now include the following parameters in addition to the SMTC configuration:

SSB frequency points;

subcarrier spacing (ssbSubcarrierSpacing);

measuring which SSBs (SSB-ToMeasure);

configuration (ss-RSSI-Measurement) when measuring RSSI (Received Signal Strength Indication);

whether the SSB index number of the neighbor cell (deriveSSB-indexfrmcell) can be obtained with the timing of the serving cell.

That is, in the prior art, if the UE changes the (special) serving cell after receiving the SSB measurement configuration configured on the network side, how to determine the SSB measurement configuration corresponding to the SSB measurement, there is no relevant solution at present.

In view of this, the embodiment of the present invention provides an SMTC configuration and an SMTC configuration use scheme, where in the scheme, when configuring an SMTC, a network side indicates an effective range thereof; after receiving the information, the UE side judges whether the current resident cell or the special service cell is in the effective range; if so, the received SMTC configuration is used.

Further, in the technical solution provided in the embodiment of the present invention, the method and the apparatus may not only be limited to determining the SMTC configuration, but also be used to determine the SSB measurement configuration, for example, to determine other configurations in the SSB measurement configuration: determining which SSBs (SSB-to measure) configuration to measure, determining the configuration (ss-RSSI-measure) when RSSI is measured, determining whether the timing of the serving cell can be used to obtain the configuration corresponding to the SSB index number (deriveSSB-indexffromcell) of the neighbor cell, and the like.

The following describes embodiments of the present invention with reference to the drawings.

In the description process, the implementation of the UE and the base station will be described separately, and then an example of the implementation of the UE and the base station in cooperation will be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such an explanation does not mean that the two must be implemented together or separately, and actually, when the UE and the base station are implemented separately, the UE and the base station solve the problems on the UE side and the base station side, respectively, and when the two are used in combination, a better technical effect is obtained.

In the implementation, mainly the SMTC is taken as an example for explanation, however, the SMTC is only one parameter in the SSB measurement configuration, and therefore, a scheme suitable for the SMTC can be used for parameters of other SSB measurement configurations by performing corresponding adjustment according to characteristics of the parameters.

Fig. 1 is a schematic implementation flow diagram of a configuration method for SSB measurement configuration on a network side, as shown in the figure, the configuration method may include:

step 101, a network side configures SSB measurement configuration, wherein the SSB measurement configuration is SSB measurement configuration with an effective range;

and step 102, sending the SSB measurement configuration to the UE.

Taking SMTC as an example, there are:

configuring an SMTC (simple message guide) at a network side, wherein the SMTC is an SMTC configured with an effective range; and sending the SMTC to the UE.

the valid range of the SSB measurement configuration is identified using a Public Land Mobile Network (PLMN) and a System Information Area Identity (SIAID) list; or the like, or, alternatively,

the valid range of the SSB measurement configuration is identified by using a PLMN and a radio access network notification area coding RNA area code list; or the like, or, alternatively,

the SSB measures whether the configuration is valid in the SIAID range of the current cell or not and uses a 1bit indication; or the like, or, alternatively,

the SSB measurement configuration uses a 1bit indication only when the current cell is valid; or the like, or, alternatively,

In the specific implementation, taking SMTC as an example, there are:

identifying a valid range of the SMTC by one or a combination of:

using 1bit to indicate whether the SMTC configuration is still effective after the SMTC configuration is in the whole network or is replaced by other service cells; or the like, or, alternatively,

identifying a valid range of the SMTC using a globally unique cell list; or the like, or, alternatively,

identifying a valid range of the SMTC using a cell list; or the like, or, alternatively,

identifying a valid range of the SMTC using a list of base stations; or the like, or, alternatively,

identifying a valid range of the SMTC using a SIAID (System information area identification) list; or the like, or, alternatively,

identifying a valid range of the SMTC using a PLMN and SIAID list; or the like, or, alternatively,

identifying a valid range of the SMTC using a PLMN and RNAearea code (RAN-based Notification Area code) list; or the like, or, alternatively,

using 1bit to indicate whether the SMTC configuration is valid in the SIAID range of the current cell; or the like, or, alternatively,

using 1bit to indicate whether the SMTC configuration is valid in the RNAarea to which the current cell belongs; or the like, or, alternatively,

using 1bit to indicate that the SMTC configuration to which the indication belongs is only effective in the current cell; or the like, or, alternatively,

and indicating whether the SMTC configuration is effective in the base station to which the current cell belongs by using 1 bit.

In practice, the effective range of the SMTC is not only collocated with the corresponding SMTC in the protocol, but can also be carried by a single information unit. Such as: a plurality of SSB measurement object configurations (including SMTC configurations corresponding to the measurement object in the configuration) and valid ranges of all the SMTC configurations may be carried in an RRCrelease message.

Specifically, the effective range may be one or more of the following:

a 1bit indication indicates that the SMTC configuration in the configuration is still effective after the whole network or other service cells are changed;

a global unique cell list;

a cell list;

base station identity (list);

a SIAID (systemInformationReaID) list or a PLMN + SIAID list;

list of { PLMN + RNAarea code };

a 1bit indication, which indicates whether the SMTC configuration in the configuration is valid within the range of the SIAID to which the current cell belongs (i.e. PLMN + SIAID broadcasted by the current cell);

a 1bit indication indicates whether the SMTC configuration in the configuration is valid in the RNAarea to which the current cell belongs;

a 1bit indication indicating that the SMTC configuration to which the SMTC belongs is valid only in the current cell; or the like, or, alternatively,

and a 1bit indication indicating whether the SMTC configuration is effective in the base station to which the current cell belongs.

In an implementation, the valid range of SMTCs is configured for all SMTCs; or the like, or, alternatively,

the valid range of the SMTC is configured for the SMTC under each measurement object.

Specifically, the effective region may be an effective region configured by all SMTCs; or may be an effective region configured for the SMTC under each measurement object.

Fig. 2 is a schematic flow chart of an implementation of a method for using an SSB measurement configuration on a UE side, as shown in the figure, the method may include:

step 201, the UE receives an SSB measurement configuration configured on the network side, where the SSB measurement configuration is an SSB measurement configuration configured with an effective range;

step 202, when the UE determines that the current cell where the UE resides or the special serving cell is within the effective range, the SSB measurement configuration is used.

Taking SMTC as an example, there are:

the method comprises the steps that UE receives an SMTC configured by a network side, wherein the SMTC is an SMTC configured with an effective range; and when the UE determines that the current resident cell or the special service cell of the UE is in the effective range, the SMTC is used.

Specifically, after receiving the information, the UE side determines whether the current camped cell or the special serving cell is within the effective range of the current camped cell or the special serving cell. If so, the received SMTC configuration is used.

acquiring SSB measurement configuration of a measurement object without effective SSB measurement configuration through a system message on a current resident cell or a special service cell, applying the acquired SSB measurement configuration to the measurement object, and executing required SSB measurement of a synchronous signal block according to the acquired SSB measurement configuration; or the like, or, alternatively,

In the specific implementation, taking SMTC as an example, there are:

when the UE determines that the current cell or the special serving cell of the UE is not within the valid range, the method further includes:

acquiring SMTC configuration of a measurement object without effective SMTC configuration through a system message on a current resident cell or a special service cell, applying the acquired SMTC configuration to the measurement object, and executing needed SSB measurement according to the determined SMTC configuration; or the like, or, alternatively,

through the system information of the current resident cell or special service cell, when the effective SMTC configuration cannot be obtained, the needed SSB measurement is not executed aiming at the measurement object; or the like, or, alternatively,

when the effective SMTC configuration cannot be obtained through the system message on the current resident cell or the special service cell, the needed SSB measurement is executed for the measurement object according to the strategy preset by the UE side; or, acquiring a time difference between the current resident cell or special service cell and the previous resident cell or special service cell, determining an effective SMTC configuration based on the time difference and the time of the current resident cell or special service cell, applying the SMTC configuration to the measurement object, and performing the required SSB measurement according to the determined SMTC configuration; or the like, or, alternatively,

not executing the SSB measurement corresponding to the SMTC which is not valid; or the like, or, alternatively,

and executing the SSB measurement corresponding to the SMTC with the configured effective range according to a preset strategy at the UE side.

Specifically, if it is not in its effective range, the UE may do the following:

determining SMTC configuration on a measurement object without effective SMTC configuration by acquiring a system message on a new cell, and executing needed SSB measurement by applying the SMTC configuration; if the system message still does not have the needed SMTC configuration, the configuration is considered invalid, the SSB measurement corresponding to the measurement object is not needed to be executed, or how to execute the SSB measurement corresponding to the measurement object depends on the realization of the UE side; alternatively, the first and second electrodes may be,

the UE autonomously obtains the time difference between the current service cell and the previous cell, and autonomously calculates the SMTC on the measurement object without effective SMTC configuration when the current service cell is taken as the time reference, and executes SSB measurement according to the updated SMTC; alternatively, the first and second electrodes may be,

the UE does not need to perform the corresponding SSB measurement in the measurement configuration; alternatively, the first and second electrodes may be,

how to perform the corresponding SSB measurements in the measurement configuration depends on the UE side implementation.

In the embodiment, the valid SMTC configuration means that when the SMTC configured with the valid range cannot be used, that is, is invalid, the UE acquires the SMTC configured by the network to the UE from the system information, and if the acquired SMTC configuration is available, the SMTC configuration is valid; an invalid SMTC configuration if not available due to a (special) serving cell change or the like.

In the specific implementation, taking SMTC as an example, there are:

and saving the SMTC and the valid range of the SMTC configuration.

Specifically, if not within its valid range, the UE may still retain the received SMTC configuration and the corresponding valid area.

the valid range of the SSB measurement configuration is identified by using a PLMN and a radio access network notification area code (RNAarea code) list; or the like, or, alternatively,

the SSB measures whether the configuration is valid in the RNAarea to which the current cell belongs and indicates by using 1 bit; or the like, or, alternatively,

In the specific implementation, taking SMTC as an example, there are:

the effective range of SMTC may be identified by one or a combination of the following:

whether the SMTC configuration is still effective after the SMTC configuration is in the whole network or is replaced by other service cells is indicated by using 1 bit; or the like, or, alternatively,

the valid range of the SMTC is identified using a PLMN and SIAID list; or the like, or, alternatively,

the valid range of the SMTC is identified by using a PLMN and a RNAarea code list; or, whether the SMTC configuration is valid in the SIAID range to which the current cell belongs uses 1bit to indicate whether the SMTC configuration is valid in the SIAID range to which the current cell belongs; or the like, or, alternatively,

whether the SMTC configuration is valid in the RNA area to which the current cell belongs is indicated by using 1 bit; or the like, or, alternatively,

the SMTC configuration only uses a 1bit indication when the current cell is valid; or the like, or, alternatively,

the SMTC configuration is indicated using 1bit when it is valid in the base station to which the current cell belongs.

The following description is given with reference to SMTC as an example in conjunction with other parameters in other SSB measurement configurations.

First, the system information and RNA mentioned in the examples will be briefly described.

Is valid for system information within a certain area.

The NR introduces system messages that are valid within the area level, considering that in some cases the system information broadcast by different cells may be the same.

In addition to the MIB (control Information Block) and SIB (System Information Block)1, other SIBs may be configured as System Information of a cell-specific (cell-specific) or an area-specific (area-specific) level. The cell-level SIB is only used in the cell, and the UE fails after leaving the current cell; the area-level SIBs are commonly used in a set SI (System Information) area, and one SI area may include one or more cells. Whether an attribute of an SIB is cell-specific or area-specific can be distinguished by whether an area scope (area scope) field corresponding to the SIB in the SIB1 exists.

The UE may store multiple sets of SIB contents at a cell/area level, and how much contents are stored depends on the memory capacity of the UE. After the UE has mobility between the cells, the stored SIB contents can be sequentially checked, and the successfully checked SIB contents are directly used as effective system information of the UE in the current cell to avoid re-reading; if the SIB required by a certain UE has no corresponding storage content, the UE is required to read the system information of the SIB in the current cell.

The mode for checking the SIB content by the UE specifically comprises the following steps:

for each version of stored SIBs (there are multiple SIBs, so SIBs are also used to represent SIBs), the SIB currently stored by the UE is considered valid and can be used directly in the current cell:

for the area-specific SIB: if the SIB stored by the UE and the corresponding SIB of the current service cell are associated with the area scope indication, and the parameters such as the stored main PLMN ID (PLMN ID; PLMN: Public Land Mobile Network, Public Land Mobile Network), SIAID (system information area ID), and valueTag (value tag) of the SIB are consistent with the parameter values of the corresponding SIB of the current service cell;

for cell-specific SIB: if the SIB stored by the UE and the corresponding SIB of the current service cell are not related to the area scope indication, and the parameters such as the main PLMN ID, the cell ID and the valueTag stored in the stored SIB are consistent with the values of the corresponding parameters of the SIB of the current service cell.

The parameters involved for SIB version checking are as follows:

1) value tag: the SIB1 contains value tag indication information for each other SIB (other SIBs), each SIB indicating separate 5-bit value tag content to identify the SIB version number broadcasted by the current cell. SIB6/7/8 for ETWS/CMAS (Earthquake and Tsunami Warning System/Commercial Mobile alarm System) does not require a valueTag indication.

2) PLMN ID: a cell may broadcast a PLMN list where the primary PLMN ID stored in the stored SIB version is compared to the primary PLMN ID in the current serving cell PLMN list for consistency.

3) SIAID (systemlnformationareaID): the length is 24bits, and the SIB identifier is unique in PLMN and is only used for identifying the use area range of the SIB of area-specific. Each cell broadcasts only one SIAID, used in conjunction with the PLMN ID.

4) Cell id (cellidentity): the length of 36bits is unique in PLMN and is used for identifying the cell.

For RNA (RAN-based Notification Area; RAN: Radio Access Network).

The NR introduces an RRC inactive (RRC: Radio Resource Control) state. And configuring an RNA for the UE in the inactive state on the network side. The UE in the non-activated state obtains a RAN notification area to which the current serving cell belongs by reading a system message (SIB1 may carry a { PLMN + RNA area code } list to which the cell belongs), and if the RAN notification area is configured in the network side, the UE does not need to notify the network side (at this time, the network side can be considered to be capable of paging the UE in the configured RNA range); if the UE is not in the RAN notification area configured on the network side, the UE needs to trigger an RNA update process to notify the anchor gNB (next generation base station) that the previously configured RNA is no longer valid, and update information between the UE and the network side in time.

Example 1:

in this example, in the case of the whole network synchronization, the network side indicates that the SMTC configuration is still valid after the whole network or cell change when configuring the measurement.

1: due to the whole network synchronization, when the network side performs configuration measurement, for example, the configuration may be measurement configuration for assisting the network side to rapidly configure CA (Carrier Aggregation) or DC (Dual Connectivity) after the non-connected UE enters the connected state, and the configuration may be dedicated RRC message configuration, or may be system message broadcast configuration, and indicate that the SMTC configuration in the configuration is still valid after the whole network or another serving cell is changed through 1-bit indication;

2: after receiving the measurement configuration, the UE may store and perform the measurement according to the prior art.

Due to the movement of the UE, the UE changes the camping cell or the (special) serving cell. In the measurement configuration received by the UE, 1bit indicates that the SMTC configuration in the configuration is still valid after the network is full or another serving cell is changed, so the UE can still perform the SSB measurement based on the previously received SMTC configuration.

In implementation, the 1bit indication may not only indicate that the SMTC configuration in the configuration is still valid after the network is full or another serving cell is changed, but also may be used to determine other configurations in the SSB Measurement configuration, such as a configuration for indicating which SSBs (SSB-to measure) are measured, a configuration when RSSI is measured (ss-RSSI-Measurement), and a configuration whether the SSB index number of a neighbor cell (deriveSSB-indexffromcell) can be obtained with the timing of the serving cell, which are still valid after the network is full or another serving cell is changed.

Example 2:

in this example, some cells may not be synchronized in time, and the network side indicates the valid areas of all SMTC configurations in the configuration.

It is assumed that all cells under one base station are synchronized, but are not synchronized with neighboring base stations, so the network side indicates the effective area of the SMTC configuration in the configuration.

1: when the network side configures measurement configuration that the network side can rapidly configure CA or DC after the non-connected UE enters the connected state, in the present discussion, such special measurement configuration is referred to as early measurement configuration (early measurement configuration) or idle measurement configuration (idle measurement configuration), and the valid area of the SMTC configuration included in the current measurement configuration is indicated, which may be in one or more of the following forms:

the effective area is a globally unique cell list, such as { cell identity1, cell identity2, … }, or { PLMN1+ cell identity1, PLMN1+ cell identity2, … };

the effective area is a cell list, such as { PCI1+ frequency1, PCI2+ frequency2, … }; wherein PCI is an abbreviation for physical cell identity;

the effective area is a base station (list), such as how many base station identifiers (Global gbb IDs) the local cell belongs to, or a plurality of base station identifier lists { Global gbb ID1, Global gbb ID 2, … };

the effective area is a system message area range list, which may be an SIAID list or a PLMN + SIAID list, for example, the network side finds that cells within a system message area scope are time-synchronized, and this configuration may be applied;

the effective region is an RNA list, which may be a { PLMN + RNA area code } list, for example, the network side finds that cells within an RNA list are all time synchronized, and this configuration can be applied;

the valid area is a 1-bit indication, which indicates whether the SMTC configuration in the configuration is valid in the SIAID range to which the current cell belongs (i.e., PLMN + SIAID broadcasted by the current cell);

the effective region is a 1bit indication, which indicates whether the SMTC configuration in the configuration is effective in the RNA area to which the current cell belongs;

the effective area is a 1bit indication, and the SMTC configuration in the configuration is indicated to be effective only in the current cell;

the valid region is a 1bit indication, indicating whether the SMTC configuration in the configuration is valid in the base station to which the current cell belongs.

2: after receiving the measurement configuration, the UE stores and performs early measurement or idle measurement according to the prior art.

Due to the movement of the UE, the UE changes the camping cell or the (special) serving cell. Assume that the camped cell or (special) serving cell is changed from the original cell1 to the cell 2. At this time, the UE needs to determine whether the cell2 belongs to the valid area of the SMTC configuration.

In a specific implementation, the globally unique cell identity (+ PLMN) information corresponding to the cell2 may be obtained by reading a system message, and the PCI (physical cell identity) and frequency may be obtained by detecting a cell2 physical signal. As for the base station identifier corresponding to the cell2, the leftmost part of the globally unique cell identifier cell identity corresponding to the cell2 is identified, and the UE can determine whether the cell2 belongs to the effective area of the SMTC according to whether the leftmost part of the cell identity is consistent with the configured base station identifier.

For example, if the effective area is the globally unique cell list and the cell identity of the cell2 is cell identity2, in the effective area of the SMTC, the UE may continue to perform the SSB measurement using the previously received SMTC configuration.

For example, if the network side indicates that the SMTC configuration in the configuration is valid only in the base station to which the current cell belongs, after switching to the cell2, the UE considers that the previously received SMTC configuration is invalid.

For example, if the effective area indicates 1bit, indicating whether the SMTC configuration in the configuration is valid in the base station to which the current cell belongs, and the base station identifier corresponding to cell1 is Global gbnb ID1, the UE determines whether the SMTC configuration is in the effective area according to whether the leftmost part of the obtained cell2 Global unique cell identifier cell identity is consistent with Global gbnb ID1, and if so, the UE may continue to perform SSB measurement using the previously received SMTC configuration; if not, the UE considers the previously received SMTC configuration invalid.

For example, if the effective area is a cell list, the PCI of the cell2 is PCI2, but the frequency is frequency 3, and the PCI2+ freuqncy3 is not in the effective area of the SMTC, the UE considers that the previously received SMTC configuration is invalid.

If the UE considers the previously received SMTC configuration to be invalid, the possible actions at this time may be as follows:

acquiring an SMTC configuration on a measurement object corresponding to an early measurement configuration (or idle measurement configuration) received before by acquiring a system message on the cell2, and performing required SSB measurement by applying the SMTC configuration; if the measurement object corresponding to the early measurement configurations (or idle measurement configurations) received before does not broadcast the corresponding SMTC configuration in the system message, the configuration is considered invalid, the SSB measurement corresponding to the measurement object does not need to be performed, or how to perform the SSB measurement corresponding to the measurement object depends on the UE side implementation; alternatively, the first and second electrodes may be,

the UE autonomously obtains the time difference between the current serving cell (namely cell2) and the previous cell2, and self-calculates the SMTC corresponding to each measurement object when the cell2 is taken as the time reference, and executes the SSB measurement corresponding to the measurement object according to the updated SMTC; alternatively, the first and second electrodes may be,

in this case, the UE does not need to perform the corresponding SSB measurement in the measurement configuration; alternatively, the first and second electrodes may be,

In particular implementations, even if the UE considers the received SMTC configuration to be invalid, the measurement configuration received before may not be deleted. As the UE moves, the camped cell or (special) serving cell changes from the original cell2 to the cell3, and if the cell3 is in the active area of the SMTC, the UE can continue to perform SSB measurements using the previously received SMTC configuration.

The active region in an embodiment may also be used to determine whether other of the SSB measurement configurations are active. Such as configuration for indicating which SSBs (SSB-to measure), configuration when measuring RSSI (ss-RSSI-measure), configuration whether the timing of the serving cell can be used to obtain the SSB index number (deriveSSB-indexffromcell) of the neighbor cell, which also need to take into account the active area. If the UE is still within the active area, the UE considers these parameters in the SSB measurement configuration to be still valid; otherwise, it is considered invalid.

Example 3:

in this example, some cells may not be synchronized in time, and the network side indicates the valid area of the SMTC configuration under each measurement object in the configuration.

It is assumed that all cells under one base station are synchronized, but are not synchronized with neighboring base stations, so the network side indicates the effective area of the SMTC configuration in the configuration. However, the present embodiment is different from embodiment 2 in that the effective region is separately allocated to the SMTC under each measurement target.

Assume that the area-specific SIB of cell1 is valid within SIAID1 of PLMN 1.

Assume that the RAN notification area to which the cell1 belongs is { PLMN1+ RAN area code 1, PLMN2+ RAN area code 2}

1: when the cell1 is configured for early measurement configurations or idle measurement configurations, it indicates the SMTC valid area under each measurement object in the current measurement configuration at the same time, for example, if the measurement configuration includes three MOs (measurement objects ), each of which includes an SMTC configuration, the network side adds 1 indication in the MO1 to indicate that the SMTC under the MO1 is valid in the area-specific range (that is, the validity of the system message area of the configuration in the cell is valid in all cells of the PLMN1+ SIAID 1);

adding 1 indication in MO2, indicating that the SMTC in MO2 is valid in the cell-specific range (i.e. the SMTC configuration is invalid after cell change); the SMTC under MO2 is indicated to be effective in the area-specific range.

2: after receiving the measurement configuration, the UE stores and performs early measurement (or idle measurement) measurement according to the prior art.

Due to the movement of the UE, the UE changes the camping cell or the (special) serving cell. Assume that the camped cell or (special) serving cell is changed from the original cell1 to the cell 2. The system message of the cell2 indicates that the primary PLMN (or the first PLMN) to which the broadcast belongs is PLMN1 and the SIAID is SIAID 1. Then the UE may consider the corresponding SMTC configurations in MO1 and MO3 received before to be valid at this time. While the corresponding SMTC configuration in MO2 is not valid. For MO2, this is possible as follows:

acquiring a system message on a cell2, acquiring an SMTC configuration of the MO2, and executing needed SSB measurement by applying the SMTC configuration; if the measurement object corresponding to the early measurement configurations (or idle measurement configurations) received before does not have the SMTC configuration of the broadcast MO2 in the system message, the configuration is considered invalid, the SSB measurement corresponding to the measurement object does not need to be performed, or how to perform the SSB measurement corresponding to the measurement object depends on the UE side implementation; alternatively, the first and second electrodes may be,

the UE autonomously obtains the time difference between the current serving cell (namely cell2) and the previous cell2, calculates the SMTC corresponding to the MO2 by taking the cell2 as a time reference, and performs SSB measurement on the MO2 according to the updated SMTC; alternatively, the first and second electrodes may be,

In particular implementations, the previously received MO2 measurement configuration may not be deleted even if the UE considers the received SMTC configuration to be invalid. As the UE moves, the camped cell or (special) serving cell changes from the original cell2 to the cell1, and the UE can perform the SSB measurement using the SMTC configuration on the MO2 received before.

If the network side finds that the cells in the RNA area to which the current cell belongs are all time-synchronized, the network side can also add a 1-bit indication to each measurement object in step 1 to indicate whether the SMTC configuration in the configuration is valid or not in the RNA area to which the current cell belongs; the rest is similar and is not described in detail herein.

In the above embodiment, early measurement configurations or idle measurement configurations are taken as an example, but it is obvious that the present solution is not limited to this configuration, and may be applied to other scenarios as long as it meets the requirement that measurement configuration is received in one cell and is executed in another cell. In addition, the scheme also does not need to limit the RRC state of the UE.

The active region in an embodiment may also be used to determine whether other of the SSB measurement configurations are active. Such as configuration for indicating which SSBs (SSB-to measure), configuration when measuring RSSI (ss-RSSI-measure), configuration whether the timing of the serving cell can be used to obtain the SSB index number (deriveSSB-indexffromcell) of the neighbor cell, which also need to take into account the active area. If the UE is still in the active area, the UE considers the parameters in the SSB measurement configuration in a certain MO to be still active; otherwise, it is considered invalid.
