Background

Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In the process of mobility management, a UE (User Equipment) needs to measure signals of neighboring cells and signals of other carriers. Due to manufacturing cost, a UE generally has only one RF (Radio Frequency) module, and thus the UE can measure or transmit data using only a single RF module. When needing to measure the adjacent cell signals with the same frequency, the UE can transmit data in the current service cell at the same time; when the signals of the inter-frequency neighboring cell or other RAT (Radio Access Technology) cell need to be measured, the UE may suspend communication with the current serving cell, adjust the RF module for measurement, readjust the RF module after a period of time, and resume communication with the serving cell. Wherein the UE suspends communication with the serving cell to measure a time interval of an inter-frequency neighbor cell or other wireless neighbor cells, which may be referred to as a measurement Gap (measgap).

Referring to fig. 1, fig. 1 is a schematic diagram illustrating a correspondence relationship between a beam sweep and an SSB burst set according to an embodiment of the disclosure. In a system where LTE (Long Term Evolution) and NR (New Radio) coexist or an NR system, a cell may transmit an SSB

(Synchronization Signal block, synchronous Signal block) burst Set to realize one-time beam scanning and cover the service range of the whole cell; the SSB burst set may be sent at a certain period to repeatedly perform beam scanning; and the UE may measure the SSB burst set within a measurement gap configured for it by the base station to switch to an endec (E-UTRA NR Dual-Connectivity) mode or NR cell.

When the network configures the sending period of the SSB burst set, factors such as system resource consumption, UE access delay and the like need to be considered; for example, configuring a shorter sending period of the SSB burst set may reduce UE access delay, reduce time and power consumption required for the UE to measure the SSB burst set, but consume more system resources; for another example, configuring a longer transmission period of the SSB burst set may reduce consumption of system resources, but may increase UE access delay. In the related art, the actual transmission period of the SSB burst set may be different, for example, the actual transmission period of the SSB burst set may be 5, 10, 20, 40, 80, 160ms, and the like.

Whereas in an LTE cell, the MGL (measgap Length) configured for a UE is typically fixed, e.g., the MGL may be 6ms or the like.

It can be seen that, in the related art, if the MGL configured by the base station for the UE cannot cover the actual transmission period of the SSB burst set, the UE may not measure the SSB burst set in the measurement gap, and thus the UE may not be quickly switched to the endec mode or the NR cell.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for configuring a measurement gap length according to an embodiment of the disclosure.

In the embodiments of the present disclosure, the measurement gap length configuration method may be applied to UEs including, but not limited to, mobile phones, tablet computers, wearable devices, sensors, internet of things devices, and other electronic devices. The UE may communicate with a base station. The base stations may include, but are not limited to, 4G base stations, 5G base stations, 6G base stations, or base stations of any generation communication system.

In one embodiment, the UE may be in an RRC CONNECTED state (RRC _ CONNECTED); the UE may reside in an LTE network.

In one embodiment, when performing the initial cell search, the UE may determine a transmission period of the SSB burst set to be 20ms specified in 3GPP (3rd Generation Partnership Project) protocol. After the initial cell search is completed, the UE may register in the LTE network, and may also receive a system message broadcasted in the current serving cell, and parse the system message to obtain an actual transmission period of the SSB burst set.

As shown in fig. 2, the method for configuring the length of the measurement gap may include the following steps:

in step 202, a transmission period of a set of bursts of synchronization signal blocks SSB is acquired.

For example, the UE may obtain a transmission period of an SSB burst set; the transmission period of the SSB burst set may specifically be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, and the like.

In step 204, a first measurement gap length MGL configured by the base station for the UE is obtained.

Wherein the first MGL may include an MGL configured by the base station for the UE.

For example, the UE may acquire a first MGL configured for it by the base station; wherein the first MGL configured for the UE in the LTE cell may be 6 ms. It should be noted that this is merely an exemplary description, and the disclosure is not limited with respect to a specific time duration of the first MGL.

In step 206, in response to determining that the measurement of the set of SSB bursts cannot be completed within the first MGL according to the transmission period of the set of SSB bursts, a second MGL for completing the measurement of the set of SSB bursts is determined.

Wherein the second MGL may include an MGL determined by the UE; that is, the UE may modify the first MGL for which the base station is configured to obtain the second MGL used to complete the measurement of the set of SSB bursts.

For example, the UE may acquire a transmission period of an SSB burst set as 10ms, and may acquire the first MGL as 6 ms; in response to determining that the measurement of the set of SSB bursts cannot be completed within the first MGL according to a transmission period of the set of SSB bursts, the UE may determine a second MGL for completing the measurement of the set of SSB bursts; when the obtained sending period of the SSB burst set is 10ms, the determined second MGL may be 11ms, or may be other time lengths that can be used to complete measurement of the SSB burst set, which is not limited in this disclosure.

In step 208, the set of SSB bursts is measured based on the second MGL.

For example, after determining that the second MGL may be 11ms in response to determining that the measurement of the set of SSB bursts cannot be completed within the first MGL according to the transmission period of the set of SSB bursts, the set of SSB bursts may be measured based on the determined second MGL.

As can be seen from the foregoing embodiments, in response to determining that measurement of the SSB burst set cannot be completed within the first MGL configured by the base station for the UE according to the obtained sending period of the SSB burst set, the UE may determine a second MGL used for completing measurement of the SSB burst set, and may measure the SSB burst set based on the second MGL. Therefore, if the first MGL configured by the base station for the UE cannot cover the transmission period of the SSB burst set, the UE may modify the MGL configured by the base station for the UE, so that the measurement of the SSB burst set may be completed based on the modified second MGL, thereby reducing the time duration for the UE to switch to the endec mode or the NR cell.

Referring to fig. 3, fig. 3 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 2. As shown in fig. 3, the obtaining a sending period of the SSB burst set may include:

in step 302, a sending period of the SSB burst set is obtained based on a system message issued by the base station.

Optionally, before the step 302, the UE may receive a system message sent by the base station. For a specific implementation manner that the base station indicates the sending period of the SSB burst set to the UE through the system message, please refer to related technologies, which is not described herein again.

For example, the UE may receive a system message sent by the base station, and obtain a sending period of the SSB burst set based on the received system message; the transmission period of the SSB burst set may specifically be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, and the like.

Optionally, before the step 302, the method may further include:

in step 304, a transmission period of the set of SSB bursts is determined to be indicated in the system message.

For example, the UE, in response to receiving the system message, may determine whether a transmission period of the set of SSB bursts is indicated in the system message; if it is determined that the system message indicates the sending period of the SSB burst set, the sending period of the SSB burst set may be obtained based on the received system message.

Optionally, in the step 304, the determining that the system message indicates the sending period of the SSB burst set may specifically include: determining that the transmission period of the set of SSB bursts is indicated in the system message in response to determining that a parameter indicating the transmission period of the set of SSB bursts is included in the system message.

For example, the UE may determine whether a system message sent by the base station includes a parameter for indicating a transmission period of the SSB burst set; in response to determining that the system message includes a parameter indicating a transmission period of the set of SSB bursts, determining that the transmission period of the set of SSB bursts is indicated in the system message; further, a sending period of the SSB burst set may be obtained based on the system message.

Optionally, in the step 304, the system message may specifically include a SIB1 message in the LTE network. Optionally, the parameter for indicating the sending period of the SSB burst set may specifically include a period serviceservingcellsib parameter included in the SIB1 message, or may also include other parameters that can be used to indicate the sending period of the SSB burst set and are included in the system message, which is not limited in this disclosure. Optionally, the obtaining the sending period of the SSB burst set based on the system message issued by the base station may specifically include: and acquiring the sending period of the SSB burst set based on the value of the parameter which is included in the system message and used for indicating the sending period of the SSB burst set.

Optionally, since the step 202 and the step 204 may be performed non-consecutively, for the convenience of subsequent processing, at the same time or after the step 302, the method may further include:

in step 306, in response to determining that the system message indicates the sending period of the SSB burst set, determining a value of a first flag and a value of a second flag; when the first flag takes a first value, the first flag may be used to indicate a transmission period of the SSB burst set indicated in the system message; when the first flag takes a second value, the first flag may be used to indicate that the transmission period of the SSB burst set is not indicated in the system message; the value of the second flag may be used to indicate the obtained sending period of the SSB burst set.

For example, the first flag may be denoted as X, the second flag may be denoted as Y, the first value may be 1, and the second value may be 0; in response to determining that the transmission period of the SSB burst set is indicated in the system message, the first flag X may be determined to be 1, and the second flag Y may be determined to be 10ms according to the transmission period (e.g., 10ms) of the SSB burst set indicated by the value of the parameter. It should be noted that, in the above illustrated embodiment, the first flag may be denoted as X, the second flag may be denoted as Y, the first numerical value may be 1, and the second numerical value may be 0, which is only an exemplary description manner and is not limited by the present disclosure.

As can be seen from the foregoing embodiment, by determining that the sending period of the SSB burst set is indicated in the system message sent by the base station, the sending period of the SSB burst set may be obtained based on the system message. Therefore, the accuracy of acquiring the sending period of the SSB burst set by the UE can be improved, and the accuracy of determining the MGL used for measuring the SSB burst set according to the sending period of the SSB burst set can be further improved, that is, the accuracy of performing MGL configuration for the UE can be improved.

Referring to fig. 4, fig. 4 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 3. As shown in fig. 4, the method may further include:

in step 402, in response to determining that the sending period of the SSB burst set is not indicated in the system message, determining the sending period of the SSB burst set to be a specified period.

The specified period may include a transmission period of an SSB burst set preconfigured for the UE.

For example, in response to receiving a system message sent by the base station, the UE may determine whether a sending period of the SSB burst set is indicated in the system message; if it is determined that the sending period of the SSB burst set is not indicated in the system message, it may be determined that the sending period of the SSB burst set is a designated period; the specified period may be 5ms, which is to be noted that this is merely an exemplary description, and the disclosure is not limited with respect to the specific duration of the specified period.

Optionally, in the step 402, the determining that the sending period of the SSB burst set is not indicated in the system message may specifically include: determining that the transmission period of the set of SSB bursts is not indicated in the system message in response to determining that the parameter indicating the transmission period of the set of SSB bursts is not included in the system message.

For example, the UE may determine whether a system message sent by the base station includes a parameter for indicating a transmission period of the SSB burst set; in response to determining that the parameter indicating the transmission period of the set of SSB bursts is not included in the system message, determining that the transmission period of the set of SSB bursts is not indicated in the system message; a transmission period of the set of SSB bursts may be determined to be the specified period preconfigured for the UE.

Optionally, in the step 402, the system message may specifically include a SIB1 message in the LTE network. Optionally, the parameter for indicating the sending period of the SSB burst set may specifically include a period serviceservingcellsib parameter included in the SIB1 message, or may also include other parameters that can be used to indicate the sending period of the SSB burst set and are included in the system message, which is not limited in this disclosure. Optionally, the obtaining the sending period of the SSB burst set based on the system message issued by the base station may specifically include: and acquiring the sending period of the SSB burst set based on the value of the parameter which is included in the system message and used for indicating the sending period of the SSB burst set.

Optionally, since the step 202 and the step 204 may be performed non-consecutively, for the convenience of subsequent processing, at the same time or after the step 402, the method may further include:

in step 404, in response to determining that the sending period of the SSB burst set is not indicated in the system message, determining a value of a first flag and a value of a second flag; when the first flag takes a first value, the first flag may be used to indicate a transmission period of the SSB burst set indicated in the system message; when the first flag takes a second value, the first flag may be used to indicate that the transmission period of the SSB burst set is not indicated in the system message; the value of the second flag may be used to indicate the designated period.

For example, the first flag may be denoted as X, the second flag may be denoted as Y, the first value may be 1, and the second value may be 0; in response to determining that a transmission period of the set of SSB bursts is not indicated in the system message, the first flag X may be determined to be 0, and the second flag Y may be determined to be 5ms according to the specified period (e.g., 5 ms).

Optionally, after the step 402, the method may further include:

in step 406, determining a third MGL corresponding to the specified period;

wherein the third MGL may include a specific MGL corresponding to the specific period, which is configured in advance for the UE.

For example, the designated period may be 5ms, and the third MGL corresponding to the designated period may be determined to be 21 ms.

In step 408, the set of SSB bursts is measured based on the third MGL.

For example, in response to determining that the sending period of the SSB burst set is not indicated in the system message sent by the base station, the UE may determine that the sending period of the SSB burst set is the designated period, where the designated period may be 5 ms; a third MGL corresponding to the designated period may be determined, and the third MGL corresponding to the designated period may be 21 ms; further, the set of SSB bursts may be measured based on the third MGL.

It should be noted that, in the above illustrated embodiment, when the specified period is 5ms, the third MGL corresponding to the specified period may be 21ms, which is merely an exemplary description and is not limited by the present disclosure; when implemented, the skilled person can flexibly configure the duration of the third MGL according to the requirements. For example, in a certain application scenario, in order to reduce the access delay of the UE and reduce the power consumption of the SSB burst set measured by the UE, the transmission period of the SSB burst set is usually not too long; if the probability that the transmission period of the acquired SSB burst set exceeds 40ms is small, the third MGL corresponding to a specified period of 5ms may be configured in advance to be 41 ms. For another example, the UE may be further configured with a correspondence between another duration of the specified period and another duration of the third MGL.

As can be seen from the foregoing embodiment, by determining that the sending period of the SSB burst set is not indicated in the system message delivered by the base station, the sending period of the SSB burst set may be determined to be the specified period. Therefore, the reliability of acquiring the sending period of the SSB burst set by the UE can be improved, and the reliability of determining the MGL for measuring the SSB burst set according to the sending period of the SSB burst set, that is, the reliability of performing MGL configuration for the UE can be improved.

Further, as can be seen from the foregoing embodiments, in response to determining that the transmission period of the SSB burst set is the specified period, a third MGL corresponding to the specified period may be determined, and the SSB burst set may be measured based on the third MGL, so that accuracy of MGL configuration for the UE may be improved.

Referring to fig. 5, fig. 5 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 2. As shown in fig. 5, the determining that the measurement of the SSB burst set cannot be completed within the first MGL according to the transmission period of the SSB burst set includes:

in step 502, if a sum of a first duration corresponding to a sending period of the SSB burst set and a preset duration is greater than a second duration corresponding to the first MGL, it is determined that the measurement of the SSB burst set cannot be completed within the first MGL.

Wherein, the first duration may include a duration corresponding to a transmission period of at least one SSB burst set; the preset duration may include a sum of durations required for the RF module carried by the UE to adjust at the start and end of the measurement gap; the second duration may include a duration corresponding to the first MGL.

For example, the sending period of the obtained SSB burst set may be 10ms, and the first duration may be 10 ms; the time length required for adjusting the RF module carried by the UE at the beginning and the end of the measurement gap may be 0.5ms, respectively, and then the preset time length may be 1 ms; the obtained first MGL configured by the base station for the UE may be 6ms, and the second duration may be 6 ms; since the sum of the first duration and the preset duration (10+1 ═ 11ms) is greater than the second duration (6ms), it may be determined that the measurement of the SSB burst set cannot be completed within the first MGL; a second MGL for completing measurement of the set of SSB bursts may be determined (e.g., the second MGL may be 11ms), and the set of SSB bursts may be measured based on the determined second MGL.

As can be seen from the foregoing embodiment, if a sum of a first duration corresponding to a sending period of the SSB burst set and a preset duration is greater than a second duration corresponding to the first MGL, the UE may determine that measurement on the SSB burst set cannot be completed in the first MGL. Therefore, whether the measurement of the SSB burst set can be completed in the first MGL is determined by judging whether the first MGL configured by the base station for the UE can cover the sending period of the SSB burst set, and then the UE can determine whether the first MGL needs to be modified, so that the time length for the UE to switch to an ENDC mode or an NR cell is reduced.

Referring to fig. 6, fig. 6 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 2. As shown in fig. 6, the determining a second MGL for completing the measurement of the SSB burst set includes:

in step 602, according to a correspondence relationship between a transmission period of an SSB burst set and a second MGL, the second MGL corresponding to the acquired transmission period of the SSB burst set is determined.

Optionally, in step 602, a corresponding relationship between a transmission period of the SSB burst set and the second MGL may be preconfigured for the UE. For example, please refer to table 1, where table 1 shows a correspondence relationship between a transmission period of an SSB burst set and a second MGL according to an embodiment of the present disclosure.

Transmission period of SSB burst set	Second MGL
		5ms	6ms
10ms	11ms
		20ms	21ms
40ms	41ms
		80ms	81ms
160ms	161ms

TABLE 1

For example, if the UE can acquire the SSB burst set with a transmission period of 10ms, and can acquire the first MGL with a transmission period of 6 ms; in response to determining that the measurement on the SSB burst set cannot be completed in the first MGL according to the sending period of the SSB burst set, the UE may determine that the second MGL corresponding to the obtained sending period of the SSB burst set may be 11ms according to a correspondence between the sending period of the SSB burst set and the second MGL shown in table 1; further, the UE may measure the set of SSB bursts based on the second MGL.

It should be noted that, in the above illustrated embodiment, the correspondence relationship between the transmission period of the SSB burst set and the second MGL shown in table 1 is merely an exemplary description, and the present disclosure is not limited thereto, and a person skilled in the art may flexibly set the second MGL corresponding to the transmission period of the SSB burst set according to needs. For example, the second MGL corresponding to the transmission cycle of the SSB burst set of 10ms may be any time length longer than 11ms, in addition to 11ms, which is not listed here.

As can be seen from the foregoing embodiments, in response to determining that the measurement on the SSB burst set cannot be completed in the first MGL according to the transmission period of the SSB burst set, a second MGL used for completing the measurement on the SSB burst set may be determined according to a corresponding relationship between the transmission period of the SSB burst set and the second MGL. Therefore, the accuracy of determining the second MGL by the UE, that is, the accuracy of MGL configuration for the UE can be improved.

Referring to fig. 7, fig. 7 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 2. As shown in fig. 7, the method further comprises:

in step 702, the set of SSB bursts is measured based on the first MGL in response to determining that the measurement of the set of SSB bursts can be completed within the first MGL according to a transmission period of the set of SSB bursts.

For example, the UE may obtain a transmission cycle of an SSB burst set as 5ms, and may obtain the first MGL configured for it by the base station as 6 ms; in response to determining that the measurement of the set of SSB bursts can be completed within the first MGL according to a transmission period of the set of SSB bursts, the UE may measure the set of SSB bursts directly based on the first MGL without re-determining the second MGL.

In the step 702, the determining that the measurement on the SSB burst set can be completed in the first MGL according to the sending period of the SSB burst set may specifically include: and if the sum of a first time length corresponding to the sending period of the SSB burst set and a preset time length is less than or equal to a second time length corresponding to the first MGL, determining that the measurement of the SSB burst set can be completed in the first MGL.

Wherein, the first duration may include a duration corresponding to a transmission period of at least one SSB burst set; the preset duration may include a sum of durations required for adjusting, by an RF module carried by the UE, a start position and an end position of a measurement gap; the second duration may include a duration corresponding to the first MGL.

For example, the sending period of the acquired SSB burst set may be 5ms, and then the first time duration may be 5 ms; the time length required for adjusting the RF module carried by the UE at the beginning and the end of the measurement gap may be 0.5ms, respectively, and then the preset time length may be 1 ms; the obtained first MGL configured by the base station for the UE may be 6ms, and the second duration may be 6 ms; since the sum of the first duration and the preset duration (5+1 ═ 6ms) is equal to the second duration (6ms), it may be determined that the measurement of the SSB burst set can be completed within the first MGL; further, the set of SSB bursts may be measured based on the first MGL.

For another example, the sending period of the obtained SSB burst set may be 10ms, and the first duration may be 10 ms; the time length required for adjusting the RF module carried by the UE at the beginning and the end of the measurement gap may be 0.5ms, respectively, and then the preset time length may be 1 ms; the first MGL may be 21ms, and the second duration may be 21 ms; since the sum of the first duration and the preset duration (10+1 ═ 11ms) is less than the second duration (21ms), it may be determined that the measurement of the SSB burst set can be completed within the first MGL; further, the set of SSB bursts may be measured based on the first MGL.

As can be seen from the foregoing embodiments, by determining that the measurement of the SSB burst set can be completed in the first MGL according to the transmission period of the SSB burst set, the SSB burst set can be measured directly based on the first MGL without modifying the first MGL by a UE, so that the accuracy of MGL configuration for the UE can be improved, and the communication efficiency can be improved.

Further, as can be seen from the foregoing embodiment, if a sum of a first duration corresponding to a sending period of the SSB burst set and a preset duration is less than or equal to a second duration corresponding to the first MGL, the UE may determine that the measurement of the SSB burst set can be completed in the first MGL. Therefore, whether the measurement of the SSB burst set can be completed in the first MGL is determined by judging whether the first MGL configured by the base station for the UE can cover the sending period of the SSB burst set, and then the UE can determine whether the first MGL needs to be modified, so that the time length for the UE to switch to an ENDC mode or an NR cell is reduced.

Referring to fig. 8, fig. 8 is a schematic flow chart of another measurement gap length configuration method based on the embodiment shown in fig. 2. As shown in fig. 8, the obtaining a first measurement gap length MGL configured by the base station for the UE includes:

in step 802, a first MGL configured by the base station for the UE is obtained based on a radio resource control RRC reconfiguration signaling sent by the base station.

Optionally, before step 802, the UE may receive an RRC (Radio Resource Control) reconfiguration signaling sent by the base station. For a specific implementation manner of the first MGL configured for the base station to indicate to the UE through the RRC reconfiguration signaling, please refer to related art, which is not described herein again.

For example, in response to receiving an RRC reconfiguration signaling sent by the base station, the UE may obtain the first MGL configured for the UE by the base station based on the RRC reconfiguration signaling.

As can be seen from the foregoing embodiment, the first MGL configured by the base station for the UE is obtained through an RRC reconfiguration signaling sent by the base station. Therefore, the accuracy of acquiring the first MGL by the UE may be improved, and the accuracy of determining the MGL used for measuring the SSB burst set according to the acquired transmission period of the SSB burst set may be further improved, that is, the accuracy of performing MGL configuration for the UE may be improved.

in step 902, a transmit period for a set of SSB bursts is obtained.

In step 903, a first MGL configured by a base station for a UE is obtained;

in step 905, determining whether the measurement on the SSB burst set can be completed in the first MGL according to a transmission period of the SSB burst set; if so, go to step 906; if not, go to step 907;

in step 906, the first MGL is maintained; continuing to execute step 910;

in step 907, determining a second MGL for completing the measurement of the set of SSB bursts; continuing to execute step 910;

in step 908, determining the sending period of the SSB burst set as a specified period;

in step 909, the third MGL corresponding to the specified period is determined; continuing to execute step 910;

in step 910, the set of SSB bursts is measured.

In the embodiment of the present disclosure, for specific implementation manners of the steps 901 to 910, please refer to specific implementation manners of related steps in the foregoing embodiments, which are not described herein again.

Optionally, in the above-illustrated embodiment, after measuring the SSB burst set based on the first MGL, the second MGL, or the third MGL, the method may further include:

in step 911, reporting a measurement event report to the base station, so that the base station determines whether to allow the UE to switch to an endec mode or an NR cell according to the measurement event report;

in step 912, in response to receiving the network configuration information sent by the base station, switching to an endec mode or an NR cell.

For example, the UE may measure the SSB burst set based on the first MGL or the second MGL or the third MGL, and may send a corresponding measurement event report to the base station; the base station may issue SCG (Secondary Cell group) configuration information to the UE according to the measurement event report; the UE may switch to an endec mode in response to receiving the SCG configuration information.

For another example, the UE may measure the SSB burst set based on the first MGL, the second MGL, or the third MGL, and report a corresponding measurement event report to the base station; the base station may send an RRC Connection Release message to the UE in response to receiving the measurement event report, where the RRC Connection Release message may carry redirected Carrier Info information for providing one or more optional NR network frequency point information; the UE may Release the currently established RRC Connection to be in an RRC IDLE state (RRC _ IDLE) again in response to receiving the RRC Connection Release message, and may perform an RRC Connection establishment procedure again in the NR to switch to the NR cell.

It should be noted that, in the above illustrated embodiment, the specific implementation manner of the UE switching to the endec mode or the NR cell after completing the measurement of the SSB burst set is merely an exemplary description, and the disclosure is not limited thereto.
