Description

SpCell determination method and device in measurement event

Technical Field

The present application relates to communications technologies, and in particular, to a method and an apparatus for determining SpCell in a measurement event.

Background

Dual Connectivity (DC) is an important technology introduced by the third generation partnership Project (3rd generation partnership Project, 3GPP) version R12, and through the Dual Connectivity technology, a Long Term Evolution (LTE) macro station and a small station can implement carrier aggregation by using an existing non-ideal backhaul (non-ideal) X2 interface, thereby providing a higher rate to a user and improving spectral efficiency and load balance by using a macro/micro-packet network. A User Equipment (UE) supporting DC can be connected to two base stations at the same time, one is a Master station (MN), and the other is a Secondary Station (SN), so as to increase throughput of a single User. Initially, in R12, MN and SN are both LTE base stations, i.e., scenarios of evolved Node B (eNB), DC under such scenarios is referred to as LTE-DC, and with the development of 5G communication technology, Non-independent Networking (NSA) in which a 5G standard (New-RAT) and LTE are combined and independent networking (Stand-Alone) of independent NR (SA) have appeared, so that a scenario in which one of MN and SN is eNB and the other is NR base station, i.e., gNB, appears in NSA, DC under such scenario is referred to as Multi-RAT Dual Connectivity (MR-DC), and MN and SN in SA are both scenarios of gNB, DC under such scenario is referred to as NR-DC.

Mobility management is an important component in wireless mobile communications, and is a general term for ensuring that a communication link between a network and a UE is not interrupted by movement of the UE. In the UE connected state, mobility management mainly refers to cell handover (handover), and cell handover is performed based on the result of measurement. The NR requires that the UE shall verify the reporting trigger condition at least when a new cell-level measurement result is generated, and when the reporting trigger condition is satisfied, the UE needs to send a measurement report to the network, and before sending the measurement report, the UE shall complete a corresponding measurement Event (Event) according to the measurement configuration given by the base station, where the measurement Event includes a1-a 6.

In TS 36.331(v15.3.0), the measurement event A3 indicates that the quality of the neighboring Cell is better than the quality of a Primary Cell (PCell) on a Primary base station or a Primary Cell (PSCell) on a Secondary base station after considering an offset value, and the measurement event a5 indicates that the quality of the PCell or PSCell is lower than a threshold 1 and the quality of the neighboring Cell is higher than a threshold 2. It can be seen that both A3 and a5 relate to a PCell or PSCell, and it is necessary to determine whether a PCell or PSCell is specifically used, so a field usescell is introduced, which when set to TRUE indicates that the event is to use a PSCell.

In TS 38.331(v15.3.0), A3 indicates that the quality of the neighbor Cell considered by the offset value is better than that of a Special Cell (SpCell), a5 indicates that the quality of the SpCell is lower than a threshold 1 and the quality of the neighbor Cell is higher than a threshold 2. Both PCell and PSCell may be referred to as SpCell, and thus it is not explicitly determined in A3 and a5 whether PCell or PSCell is specifically used, resulting in that the UE cannot explicitly perform the SpCell on which A3 and a5 are based, thereby affecting cell handover.

Disclosure of Invention

The application provides a SpCell determination method and device in a measurement event, so that fields in signaling are saved, and signaling overhead is reduced.

In a first aspect, the present application provides a method for determining an SpCell in a measurement event, where a UE receives a signaling sent by a base station, where the signaling includes measurement configuration information, and then the UE determines, according to the signaling, the SpCell used for the measurement event, where the measurement event is indicated by the measurement configuration information.

The method and the device have the advantages that the SpCell used by the UE for the measurement event is determined through the signaling which is sent to the UE by the base station and comprises the measurement configuration information, the fields in the signaling are saved, and the signaling overhead is reduced.

In a possible implementation, when a primary station MN and a secondary station SN are connected simultaneously, the UE may determine one of the primary cells PCell and PSCell in the MN as the SpCell. Namely, the UE determines the base station generating the measurement configuration information; when the base station generating the measurement configuration information is MN, determining the PCell as the SpCell; when the base station generating the measurement configuration information is SN, the PSCell is determined to be SpCell. The UE determines the base station generating the measurement configuration information, which may include determining the base station generating the measurement configuration information according to a field name and/or a cell name in the signaling; or, when the container with the measurement configuration information is analyzed from the signaling, another base station except the base station sending the signaling is determined as the base station generating the measurement configuration information.

In the DC scene, the signaling which is sent to the UE by the base station and comprises the measurement configuration information confirms whether the SpCell used by the UE for measuring events is the PCell or the PSCell, so that fields in the signaling are saved, and the signaling overhead is reduced.

In a possible implementation manner, after receiving the signaling sent by the base station, the UE may determine whether the measurement event is A3 and/or a5 according to the measurement configuration information; determining the SpCell according to the signaling if the measurement event is A3 and/or A5.

The present application determines whether the SpCell is a PCell or a PSCell only in measurement events A3 and/or a5, reducing workload.

In one possible implementation, the UE may determine whether the measurement event is A3 and/or a5 according to the measurement configuration information after determining the SpCell used for the measurement event according to the signaling; if the measurement event is A3 and/or a5, then A3 and/or a5 measurements are made according to SpCell.

In one possible implementation, when only one base station is connected, the UE may determine a primary cell PCell of the base stations as the scell.

In a second aspect, the present application provides a method for determining a SpCell in a measurement event, where only when a PSCell and a PCell support the same communication system and the measurement event is A3 and/or a5, a base station sets a cell indication field in measurement configuration information and sends a signaling including the measurement configuration information to a UE. The cell indication field may be usescell, and the base station sets its value to TRUE if it wants the UE to use PSCell for measurement event A3 and/or a 5.

In a DC scene, the signaling including measurement configuration information sent to the UE by the base station confirms whether the SpCell used by the UE for measuring events is a PCell or a PSCell, so that the cell quality can be prevented from being directly compared among cells of different standards in an A3 event, and the cell quality can be prevented from being compared with a threshold set for the cross-standard cell quality in an A5 event.

In a possible implementation manner, the determining module is specifically configured to determine, according to a field name and/or a cell name in a signaling, a base station that generates measurement configuration information; or, when the container with the measurement configuration information is analyzed from the signaling, another base station except the base station sending the signaling is determined as the base station generating the measurement configuration information.

In a possible implementation manner, the determining module is further configured to determine whether the measurement event is A3 and/or a5 according to the measurement configuration information; determining the SpCell according to the signaling if the measurement event is A3 and/or A5.

In one possible implementation manner, the method further includes:

Detailed Description

To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a flowchart of a first embodiment of a SpCell determination method in a measurement event according to the present application, as shown in fig. 1, the method of the present embodiment is executed by a UE, and the method may include:

step 101, receiving a signaling sent by a base station, where the signaling includes measurement configuration information.

In the measurement configuration phase, the base station signals information required for performing relevant measurement events to the UE. For example, in the connected state, the signaling sent by the base station may be Radio Resource Control (RRC) reconfiguration (rrcreeconfiguration), and the cell measconfiguration of rrcreeconfiguration includes measurement configuration information sent to the UE. The measurement configuration information may include a measurement object (measurement object), reporting configuration (reporting configuration), measurement identity (measurement identity), measurement configuration (qualification), measurement interval configuration, and the like.

And step 102, determining the SpCell used for the measurement event according to the signaling, wherein the measurement event is indicated by the measurement configuration information.

The measurement events (events) include a1 (i.e., serving cell quality is above the threshold), a2 (i.e., serving cell quality is below the threshold), A3 (i.e., neighbor quality is better than PCell or PSCell quality after considering the offset value), a4 (i.e., neighbor quality is higher than the threshold), a5 (i.e., PCell or PSCell quality is lower than threshold 1, neighbor quality is higher than threshold 2), and a6 (i.e., neighbor quality is better than SCell quality after considering the offset value). Through the reporting configuration in the measurement configuration information, the base station informs the UE of details of measurement to be performed, including the type of measurement, the reporting trigger mode, the reporting format, and the like, and it can be seen that the measurement event that the base station requires the UE to perform may be indicated by the measurement configuration information. Since A3 and a5 relate to the selection of PCell and PSCell, and the object to be used is already specified in TS 36.331 by the field usescell, it is necessary to specify whether the scell used in TS 38.331 is PCell or PSCell. The present application may make this selection based on signaling without usescell.

The technical solution of the embodiment of the method shown in fig. 1 will be described in detail below by using several specific examples.

In a possible implementation manner, the UE may connect to one MN and one SN at the same time, where the MN and the SN are both enbs, the MN is an eNB, the SN is a gNB, the MN is a gNB, the SN is an eNB, or the MN and the SN are both gnbs, and in the last three scenarios, the gNB is involved, and a field usescell in TS 36.331 is not defined in the NR protocol TS 38.331 to distinguish the PCell from the PSCell. Therefore, the present application provides a solution on the basis of TS 38.331, fig. 2 is a flowchart of a second embodiment of the SpCell determination method in the measurement event of the present application, and as shown in fig. 2, the method of this embodiment may include:

step 201, receiving a signaling sent by a base station, where the signaling includes measurement configuration information.

In the application, the UE is simultaneously connected with one MN and one SN, usually, the MN sends a Signaling including measurement configuration information to the UE through a Signaling Radio Bearer (SRB) 1, the SN sends the Signaling including the measurement configuration information to the UE through an SRB3, the SN sends the measurement configuration information to the MN firstly under the condition that the SRB3 is not configured, and then the MN forwards the measurement configuration information to the UE.

Step 202, determining the base station generating the measurement configuration information.

In the application, the UE can determine the base station for generating the measurement configuration information according to the field name and/or the cell name in the signaling; or, when the container with the measurement configuration information is analyzed from the signaling, another base station except the base station sending the signaling is determined as the base station generating the measurement configuration information.

In general, a base station sending signaling is a base station generating measurement configuration information, for example, fig. 3 to fig. 5 are signaling diagrams of a second embodiment of the SpCell determination method in the measurement event of the present application, as shown in fig. 3, a MN configures a measurement event A3 or a5 for a UE, generates measurement configuration information, and carries a measConfig containing the measurement configuration information in a signaling rrcrconfiguration according to an existing protocol, where the measConfig may have one or more configurations (reportConfig), and when the reportConfig is an event trigger type, the reportConfig may include a measurement event (e.g., A3 or a 5). As shown in fig. 4, the SN configures a measurement event A3 or a5 for the UE, generates measurement configuration information, and carries measConfig containing the measurement configuration information in the signaling rrcreeconfiguration according to the existing protocol SN, where there may be one or more reportconfigs in the measConfig, and when the reportConfig is an event trigger type, the reportConfig may include a measurement event (e.g., A3 or a 5). The SN forwards the measurement configuration information of event A3 or a5, which the UE wants to measure, to the UE through the MN, and there are two implementation methods for this process: one is through a Container (Container), which may be an RRC message or an Information Element (IE). For example, as shown in fig. 5, what is contained in the Container strip is rrcreeconfiguration (rrcreeconfiguration belongs to the RRC message). The message sent by the MN to the UE comprises: XXX (a field name) octetetstring (associating rrcreconfigurable by SN, and then sent to MN through inter-node message. As another example, contained within is an IE. The message sent by the MN to the UE comprises: XXX (a certain field name) OCTET STRING (connecting measConfig), which is configured by SN, and then sent to MN through inter-node message. The measConfig may be replaced by other named fields, such as measConfigSCG, which is not specifically limited in this application. Optionally, the Container may be placed in a measConfig configured by the MN to the UE, that is, the RRCReconfiguration sent by the MN to the UE includes the measConfig (measurement configuration information configured by the MN to the UE), and the measConfig includes the Container (measurement configuration information configured by the SN to the UE): XXX (a certain field name) OCTET STRING (associating means Config). Another is through an IE, for example, the SN is configured for the UE and defined by a separate IE, the MN carries the IE in the measConfig of rrcreconfigurability sent to the UE, the IE may include one or more fields, the IE configured for the UE by the SN carries an identifier of the SN, or the field in the IE configured for the UE by the SN carries an identifier of the SN, and the UE may know which measurement configuration information configured for the UE by the SN according to the identifier. For example, there may be measConfig in the RRCReconfiguration, and in one possible implementation, there may be a cell measConfigSCG in the RRCReconfiguration in addition to the measConfig, or some fields in the existing measConfig are determined by SN, for example, a Measurement Object (MO) corresponds to a frequency point in LTE, and in MO configuration, the base station will inform the UE of necessary information that needs to be known for Measurement of the frequency point, including configuration conditions of Measurement resources on the frequency point, a cell list on the frequency point, and so on. There is a field measidtoaddmost in the MO, followed by a field measidttoaddmodlist-SCG, from which the UE can know whether MN or SN is provisioned. The UE can determine whether the base station generating the measurement configuration information is MN or SN according to a field (field) name and/or an Information Element (IE) name in the received signaling. It should be noted that, in the present application, the SN mentioned above is only an example of a field name, a cell name, and the like involved in the process of forwarding the measurement configuration information of the event A3 or a5, which is intended to be measured by the UE, to the UE through the MN, and the present application is not limited to this.

And step 203, when the base station generating the measurement configuration information is the MN, determining the PCell as the scell.

And step 204, when the base station generating the measurement configuration information is the SN, determining the PSCell as the SpCell.

Through step 202, the UE may determine whether the base station generating the measurement configuration information is the MN or the SN, and then the UE may determine the SpCell to be used when performing the measurement event, that is, when the base station generating the measurement configuration information is the MN, the UE performs the measurement event using the primary cell PCell of the MN, and when the base station generating the measurement configuration information is the SN, the UE performs the measurement event using the primary cell PSCell of the SN. Exemplarily, the following shows the behavior of the UE of the present application when receiving the measurement configuration information of the base station to the configured measurement events A3 and a 5:

(1) measurement event A3 (better than SpCell after neighbor quality consideration offset value)

The UE will:

measurement event a3 is performed using PCell, provided measConfig is configured by the MN.

Measurement event a3 is performed using the PSCell, provided measConfig is configured by the SN.

(2) Measurement event A5(SpCell quality below threshold 1, neighborhood quality above threshold 2)

The UE will:

measurement event a5 is performed using PCell, provided measConfig is configured by the MN.

Measurement event a5 is performed using the PSCell, provided measConfig is configured by the SN.

In a possible implementation manner, after receiving the signaling sent by the base station, the UE may determine whether the measurement event is A3 and/or a5 according to the measurement configuration information, and determine the SpCell according to the signaling if the measurement event is A3 and/or a 5. As described above, of the measurement events a1-a6, only A3 and a5 are involved in the selection of PCell and PSCell, so in order to reduce the workload of the UE, a premise may be preset that the UE needs to determine the SpCell only if the measurement event configured by the base station is A3 and/or a 5.

In addition, after determining the SpCell, the UE may only need to perform the corresponding measurement event using the determined SpCell if the measurement event is A3 and/or a 5.

In a possible implementation, the UE is connected to only one base station, and correspondingly, only one primary cell PCell, so that the PCell may be explicitly used in the event of A3 or a5, and the PSCell does not need to be considered.

The technical solution implemented by the UE in the above method embodiments of the present application may also be implemented by a component (e.g., a chip or a circuit) that can be used for the UE.

In a possible implementation manner, the UE may simultaneously connect to one MN and one SN, where the MN and the SN are both enbs, the MN is an eNB, the SN is a gNB, the MN is a gNB, the SN is an eNB, or both the MN and the SN are both gnbs, and two base stations to which the UE is simultaneously connected are both different communication systems in two intermediate scenarios, where the scenario is MR-DC, and the scenarios include E-UTRA and NR Dual Connectivity (E-UTRA-NR Dual Connectivity, abbreviated as EN-DC) (MN is an eNB, SN is a gNB), NG-Radio Access Network E-UTRA and NR Dual Connectivity (NG-Radio Access Network E-UTRA-NR Dual Connectivity, abbreviated as NE-DC) (eNB, SN is a gNB), and NR and E-UTRA Dual Connectivity (NR-E-UTRA Dual Connectivity, abbreviated as NE-DC) (MN is a gNB, SN is an eNB). For the measurement event A3, because the quality of the neighbor cell and the PCell or the PSCell are directly put together for comparison, in an MR-DC scenario, the PCell and the PSCell must be of different standards, and if the measurement event A3 is applied to the neighbor cell of the event A3 and the PCell of the same standard, according to TS 36.331, if the usescell is TRUE, the event A3 is to compare the neighbor cell with the PSCell, so that two cells of different standards are compared, but this situation should be avoided as much as possible. For the measurement event a5, although a5 and PCell/PSCell are compared with thresholds respectively, the thresholds are configured according to LTE, so that it is also avoided to compare a cell of NR system with a threshold set for an LTE cell, and to compare a cell of LTE system with a threshold set for an NR cell. Based on the solution provided in this application, fig. 6 is a flowchart of a third embodiment of the SpCell determination method in the measurement event of this application, and as shown in fig. 6, the method of this embodiment may include:

step 301, only when the PSCell and the PCell support the same communication system and the measurement event is A3 and/or a5, setting a cell indication field in the measurement configuration information.

Step 302, signaling including measurement configuration information is sent to the UE.

The cell indication field may be a usescell, the usescell field is set by the base station when the measurement configuration information is configured only when the PSCell and the PCell support the same communication system and the measurement event is A3 and/or a5, and the value of the usescell is set to TRUE by the base station if the UE needs to use the PSCell. The UE would then adopt the PSCell in performing an A3 and/or a5 measurement event according to the settings. For example, in the following scenario of EN-DC, after the MN configures the UE with a measurement task according to TS 36.331, the UE is based on the behavior of usescell when receiving measurement configuration information of a measurement event A3 and/or a5 configured by the base station:

usePSCell

the MN (i.e., eNB) sets this field to TRUE only if the PSCell and PCell support the same communication scheme and the measurement event is A3 and/or a 5.

If this field is set to TRUE, the UE will use the PSCell.

Contrary to the above scenario, when the PSCell and PCell support different communication schemes, that is, in the above MR-DC scenario, the MN may not set a cell indication field in the measurement configuration information of the measurement event A3 and/or a5 configured to the UE, based on which the UE may determine that the primary cell PCell of the MN can only be used to execute the A3 and/or a5 event, and the PCell and the neighboring cell necessarily support the same communication scheme. For example, in EN-DC, the MN is an eNB, the SN is a gNB, the MN configures an A3 event for the UE, and the measurement configuration information does not carry the usescell, so that the UE performs an A3 event using the PCell when performing an A3 event, where the PCell and the neighboring cell are both cells of an LTE system. In NE-DC, MN is gNB, SN is eNB, MN configures A3 event for UE, and measurement configuration information does not carry usePCell, so that UE uses PCell to perform A3 event when executing A3 event, and at this time, PCell and adjacent cell are NR type cells.

The technical solution implemented by the base station in the above method embodiments of the present application may also be implemented by a component (e.g., a chip or a circuit) that can be used for the base station.
