Description

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

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

Technical Field

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

Background

The SMTC (synchronization signal block measurement time configuration, SS/PBCH Block Measurement Time Configuration) will be described first.

NR (New Radio) RRM (Radio resource management ) measurement currently supports measurement objects for both pilots, including SSB (synchronization signal block ) and CSI-RS (channel state information pilot, CHANNEL STATE information REFERENCE SIGNAL). In NR, each cell transmits a set of SSB blocks in a configured period and pattern. To inform the UE (User Equipment) about the specific moment of searching and measuring SSB, the network may configure SSB block RRM measurement timing configuration SMTC for the UE. The SMTC configuration includes:

-a measurement window period (Periodicity), preferably {5,10,20,40,80,160} ms;

Time offset (offset) within a period,

-The measurement window duration {1,2, once again, 5 ms.

The time of occurrence of each SMTC is based on the NR SpCell (SPECIAL CELL ) or the time of the current camping cell, and the corresponding SFN (system frame number ) and the first subframe (subframe) of occurrence are calculated as follows:

SFN mod T＝(FLOOR(Offset/10))；

Subframe=offset mod 10 if Periodicity is greater than 5 ms; subframe=offset or (offset+5);

wherein t=ceil (Periodicity/10).

The network side will configure one SMTC for each SSB-based measurement object. For SSB measurement with the same frequency, an SMTC with a smaller period may be configured for some cells for faster acquisition of measurement results of the corresponding cells.

The prior art has the following defects:

SMTC is based on the time of the current camping cell (for the non-connected state) or the special serving cell (for the connected state). In actual deployment, however, some cells are fully synchronized in time; some cells are not synchronized in time and there is a time difference. If the UE receives SMTC configured on the network side, it changes the (special) serving cell, how to determine SMTC corresponding to SSB measurement, and there is no relevant solution at present.

Detailed Description

The inventors noted during the course of the invention that:

When SSB is measured in NR, the network informs the UE to search and measure the time window SMTC of SSB. But the configuration is based on the time of the current camping cell (for the non-connected state) or the special serving cell (for the connected state). If the UE receives SMTC configured on the network side, changes the (special) serving cell, how to determine SMTC corresponding to SSB measurement, and there is no related solution at present.

Further, the inventors also noted that:

in addition to including SMTC configurations, SSB measurement configurations may currently include the following parameters:

SSB frequency points;

a subcarrier spacing (ssbSubcarrierSpacing);

which SSBs (SSB-ToMeasure) are measured;

configuration (ss-RSSI-Measurement) when measuring RSSI (received signal strength Indication );

Whether or not the SSB index number of the neighbor cell can be obtained with the timing of the serving cell (deriveSSB-IndexFromCell).

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 is also not related to the present solution.

In view of this, the embodiment of the invention provides the configuration of the SMTC and the use scheme of the SMTC configuration, in which the network side indicates the effective range when configuring the SMTC; after the UE side receives the information, judging 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 may not be limited to determining SMTC configuration, but may also be used to determine SSB measurement configuration, for example, to determine other configurations in SSB measurement configuration: the configuration of which SSBs (SSB-ToMeasure) to measure, the configuration when the RSSI is measured (ss-RSSI-Measurement), the configuration of whether the timing of the serving cell can be used to obtain the SSB index number (deriveSSB-IndexFromCell) correspondence of the neighbor cell, etc.

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

In the description process, the description will be made from the implementation of the UE and the base station, respectively, and then an example of the implementation of the cooperation between the UE and the base station will be given to better understand the implementation of the solution given in the embodiment of the present invention. Such a description does not mean that the two must be implemented cooperatively or separately, and in fact, when the UE and the base station are implemented separately, they solve the problems of 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, SMTC will be mainly described as an example, but SMTC is only one parameter in the SSB measurement configuration, so that a scheme suitable for SMTC can be used for parameters of other SSB measurement configurations by performing corresponding adjustment according to characteristics of parameters, and it should be noted that, even if parameters in the SSB measurement configuration are increased or decreased, as long as properties of the parameters are similar to those of SMTC, the scheme provided in the embodiment of the present invention can be adopted, so that the implementation of SMTC is only used for teaching a person skilled in the art how to implement the present invention specifically, but it is not meant to be used only for SMTC, and a corresponding manner can be determined in combination with practical needs in the implementation process.

Such as: a plurality of SSB measurement object configurations (including SMTC configurations corresponding to the measurement objects among the configurations) and the valid ranges of all SMTC configurations may be carried in RRCRELEASE (RRC release) messages.

Specifically, if not in its effective range, the UE may do so by:

Determining the SMTC configuration on the measurement object without the valid SMTC configuration by acquiring the system message on the new cell, and executing the required SSB measurement by applying the SMTC configuration; if the required SMTC configuration still does not exist in the system message, the configuration is considered invalid, SSB measurement corresponding to the measurement object does not need to be performed, or how to perform SSB measurement corresponding to the measurement object depends on UE side implementation; or alternatively

The UE autonomously obtains the time difference between the current serving cell and the previous cell, autonomously calculates the SMTC on the measurement object which is not provided with effective SMTC when the current serving cell is taken as a time reference, and executes SSB measurement according to the updated SMTC; or alternatively

The UE need not perform corresponding SSB measurements in the measurement configuration; or alternatively

In the embodiment, the valid SMTC configuration refers to an SMTC configuration that, when the SMTC with the valid range is not available, i.e. invalid, the UE will acquire 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; if not available due to a change of (special) serving cell, etc., an invalid SMTC configuration.

Whether the SMTC configuration is valid within the RNA area to which the current cell belongs is indicated using 1 bit; or alternatively, the first and second heat exchangers may be,

The SMTC configuration uses a 1bit indication only when the current cell is active; or alternatively, the first and second heat exchangers may be,

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

Examples of other parameters in other SSB measurement configurations are described below, with SMTC being the dominant.

First, system information and RNA related to the examples will be briefly described.

And is valid for system information within a certain area.

Considering that in some cases the system information broadcast by different cells may be the same, an active system message at the regional level is introduced in the NR.

In addition to MIB (control information block Master Information Block) and SIB (system information block System Information Block) 1, other SIBs may be configured as cell-specific (cell-specific) or area-specific (area-specific) system information. The cell-level SIB is only used in a cell, and the UE fails after leaving the current cell; and the region-level SIB is common in a set SI (system information ) region, one SI region may include one or more cells. Whether a SIB has a cell-specific or area-specific attribute can be distinguished by the presence or absence of a corresponding areaScope (area range) field of the SIB in SIB 1.

The UE may store multiple sets of SIB contents at multiple cell/region levels, with the amount of stored contents depending on the memory capacity of the UE. After the UE is in mobility between cells, the stored SIB contents can be checked in sequence, and the SIB contents which are checked successfully are used as the effective system information of the UE in the current cell directly, so that re-reading is avoided; and if the SIB required by a certain UE does not have corresponding storage content, the UE is required to read the system information of the SIB of the current cell.

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

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

For the area-specific SIB: if the SIB stored by the UE and the corresponding SIB of the current service cell are both associated with areaScope indication, and the parameters such as the main PLMN ID (PLMN identifier; PLMN: public land mobile network, public Land Mobile Network), SIAID (system information area identifier, systemInformationAreaID), valueTag (value tag) and the like stored by the stored 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 indicated by the association areaScope, and the parameters of the stored SIB, such as the main PLMN ID, the cell ID, valueTag and the like, are consistent with the corresponding parameter values of the SIB of the current service cell.

The parameters involved for SIB version verification are as follows:

1) valueTag: the SIB1 contains valueTag indication information for each other SIB (other SIBs), each SIB indicating a separate 5-bit valueTag content to identify the SIB version number broadcast by the current cell. SIB6/7/8 for ETWS/CMAS (earthquake and tsunami warning system/commercial mobile warning system, earthquake and Tsunami WARNING SYSTEM/Commercial Mobile ALERT SYSTEM) does not require valueTag indication.

2) PLMN ID: one cell may broadcast a PLMN list where the stored SIB version is compared for agreement between the primary PLMN ID in the stored primary PLMN and the current serving cell PLMN list.

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

4) Cell ID (CellIdentity): the length 36bits, unique within the PLMN, is used to identify the cell.

For RNA (RAN notification area, RAN-based Notification Area; RAN: radio access network, radio Access Network).

RRC INACTIVE (RRC inactive; RRC: radio resource control; radio Resource Control) states are introduced in the NR. The network side configures one RNA for the inactive UE. The inactive state UE obtains the RAN notification area of the current serving cell by reading a system message (a { PLMN+RNA area code } list which possibly carries the cell in SIB 1), if the current serving cell belongs to the RAN notification area, the UE does not need to notify the network side (the network side can be considered to page the UE in the configured RNA range at the moment); if the configured RNA is not within the RAN notification area, the UE needs to trigger an RNA update process to inform the anchor gNB (next generation base station, next generation NodeB) that the previously configured RNA is no longer valid and update the information between the UE and the network in time.

Example 1:

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

1: Because of the whole network synchronization, when the network side performs configuration measurement, for example, the configuration may be a measurement configuration for assisting the network side to rapidly configure CA (carrier aggregation ) or DC (dual connectivity, dual Connectivity) after the non-connected UE enters the connected state, the configuration may be a dedicated RRC message configuration, or may be a configuration through system message broadcast, and through a 1bit indication, it indicates that SMTC configuration in the configuration is still valid after the whole network or other serving cells are changed;

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

Due to the movement of the UE, the UE replaces the camping cell or the (special) serving cell. In the measurement configuration received by the UE, the SMTC configuration in the configuration is indicated to be still valid after the whole network or other serving cells are changed by 1bit, so the UE can still perform SSB measurement based on the SMTC configuration received previously.

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

Example 2:

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

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

1: When the network side configures a measurement configuration for assisting the non-connected UE to enter a connected state and the network side can quickly configure CA or DC, the special measurement configuration is referred to as early measurement configurations (early measurement configuration) or idle measurement configurations (idle measurement configuration) in the current discussion, and the effective area of SMTC configuration included in the current measurement configuration is indicated by one or more of the following forms:

the active area is a globally unique cell list such as { CELL IDENTITY1, CELL IDENTITY, … }, or { PLMN1+ CELL IDENTITY, PLMN1+ CELL IDENTITY2, … };

the active area is a cell list, such as { PCI1+ frequency1, PCI2+ frequency2, … }; wherein PCI is an abbreviation for PHYSICAL CELL IDENTITY;

the active area is a base station (list), such as the number of base station identities (Global gNB IDs) to which the cell belongs, or a plurality of base station identity lists { Global gNB IDs 1,Global gNB ID 2, … };

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

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

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

the effective area 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, which indicates that the SMTC configuration in the configuration is effective only in the current cell;

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

2: After the UE receives the measurement configuration, early measurement (early measurement) or idle measurement measurements are stored and performed according to the prior art.

Due to the movement of the UE, the UE replaces the camping cell or the (special) serving cell. It is assumed that the camping cell or (special) serving cell is changed from cell1 to cell2. At this time, the UE needs to determine whether cell2 belongs to the active area of SMTC configuration.

In a specific implementation, the globally unique cell identifier (+plmn) information corresponding to the cell2 may be obtained by reading a system message, and the PCI (physical layer cell identifier, PHYSICAL CELL IDENTITY) and frequency may be obtained by detecting a cell2 physical signal. As for the base station identifier corresponding to the cell2, which is the leftmost part of the globally unique cell identifier CELL IDENTITY corresponding to the cell2, the UE may determine whether the cell2 belongs to the SMTC valid region according to whether the leftmost part of CELL IDENTITY is consistent with the base station identifier in the configuration.

If the active area is a globally unique cell list, for example, CELL IDENTITY for cell2 is CELL IDENTITY 2, then in the active area of SMTC, the UE may continue to perform SSB measurements 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 changing to cell2, the UE considers that the SMTC configuration received previously is invalid.

If the effective area is indicated by 1bit, for example, it indicates whether SMTC configuration in the configuration is effective in a base station to which the current cell belongs, and the base station identifier corresponding to the cell 1 is Global gNB ID 1, then the UE determines whether the SMTC configuration received before is used to perform SSB measurement according to whether the leftmost part of the obtained Global unique cell identifier CELL IDENTITY of the cell2 is consistent with Global gNB ID 1, if so, the UE may continue to use the SMTC configuration received before; if not, the UE considers the previously received SMTC configuration invalid.

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

If the UE considers the previously received SMTC configuration invalid, then possible practices may be as follows:

Acquiring the SMTC configuration on the measurement object corresponding to early measurement configurations (or idle measurement configurations) received before by acquiring the system message on the cell2, and executing the required SSB measurement by applying the SMTC configuration; if the previously received early measurement configurations (or idle measurement configurations) corresponding measurement object does not broadcast the corresponding SMTC configuration in the system message, then the configuration is deemed invalid, SSB measurement corresponding to the measurement object is not required to be performed, or how to perform SSB measurement corresponding to the measurement object depends on UE side implementation; or alternatively

The UE autonomously obtains the time difference between the current serving cell (namely cell 2) and the cell2 of the previous cell, and autonomously calculates the SMTC corresponding to each measurement object when the cell2 is taken as a time reference, and executes SSB measurement corresponding to the measurement object according to the updated SMTC; or alternatively

In this case, the UE does not need to perform the corresponding SSB measurement in the measurement configuration; or alternatively

In particular implementations, the UE may not delete the previously received measurement configuration even if it considers the received SMTC configuration invalid. As the UE moves, the camping cell or (special) serving cell changes from original cell2 to cell3, and if cell3 is in the SMTC's active area, the UE may continue to perform SSB measurements using the previously received SMTC configuration.

The active area in an embodiment may also be used to determine whether other ones of the SSB measurement configurations are active. Such as a configuration for indicating which SSBs (SSB-ToMeasure) to measure, a configuration when RSSI is measured (ss-RSSI-Measurement), a configuration whether the SSB index number (deriveSSB-IndexFromCell) of the neighbor cell can be obtained with the timing of the serving cell, the above parameters also need to take the active area into account. 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 case, some cells may not be synchronized in time, and the network side indicates the effective area of SMTC configuration under each measurement object in the configuration.

It is assumed that all cells under one base station are synchronized, but not synchronized with neighbor base stations, so the network side indicates the effective area of SMTC configuration in the configuration. However, the present embodiment differs from embodiment 2 in that the effective areas are respectively configured for SMTCs under each measurement object.

The area-specific SIB for cell1 is assumed to be valid within SIAID a of PLMN 1.

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

1: When cell1 is configured for early measurement configurations or idle measurement configurations, simultaneously indicating the SMTC valid area under each measurement object in the current measurement configuration, for example, the measurement configuration includes three MOs (measurement objects, measurement object) each including the SMTC configuration, then the network side adds 1 indication to the MO1 to indicate that the SMTC under the MO1 is valid in the area-specific range (i.e. the configuration is valid in all cells whose system message area validity of the cell is PLMN1+ SIAID);

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

2: After the UE receives the measurement configuration, early measurement (or idle measurement) measurements are stored and performed according to the prior art.

Due to the movement of the UE, the UE replaces the camping cell or the (special) serving cell. It is assumed that the camping cell or (special) serving cell is changed from cell1 to cell2. The main PLMN (or first PLMN) to which the broadcast belongs in the system message of cell2 is PLMN1, SIAID is SIAID. The UE may then consider the corresponding SMTC configuration in both MO1 and MO3 as previously received to be valid. While the corresponding SMTC configuration in MO2 is invalid. For MO2, possible practices at this time may be as follows:

acquiring the SMTC configuration of MO2 by acquiring a system message on cell2, and executing SSB measurement required by applying the SMTC configuration; if the previously received early measurement configurations (or idle measurement configurations) corresponding measurement object does not broadcast SMTC configuration of MO2 in the system message, then the configuration is considered invalid, SSB measurement corresponding to the measurement object is not required to be performed, or how to perform SSB measurement corresponding to the measurement object depends on UE side implementation; or alternatively

The UE autonomously obtains the time difference between the current serving cell (namely cell 2) and the cell2 of the previous cell, autonomously calculates the SMTC corresponding to MO2 when the cell2 is taken as a time reference, and executes SSB measurement on MO2 according to the updated SMTC; or alternatively

In an implementation, the UE may not delete the MO2 measurement configuration received before even if it considers the received SMTC configuration invalid. As the UE moves, the camping cell or (special) serving cell changes from cell2 to cell1, the UE may perform SSB measurements using SMTC configuration on MO2 received previously.

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 increase a 1bit indication for each measurement object in the step 1 to indicate whether the SMTC configuration in the configuration is effective or not in the RNA area to which the current cell belongs; the remainder 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 can be applied to other scenarios as long as it is desirable to receive a measurement configuration under one cell but perform the measurement configuration under another cell. In addition, the scheme also does not need to limit the RRC state of the UE.

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