In order to meet the performance index of LTE-A, especially reach the performance requirement of LTE-A to Cell Edge User, coordinated multipoint transmission (Coordinated Multiple Point Transmission and Reception, referred to as CoMP) technology is suggested.CoMP transmission technology is counted as raising community marginal user performance, effectively suppresses one of important technology of presence of intercell interference.LTE-A system can increase by CoMP technology the covering of high data rate, thereby improves the throughput of cell edge, further improves throughput of system.So-called CoMP refers to a plurality of evolved base station (evolved NodeB separated on geographical position, referred to as eNB), or the transfer of data that claims a plurality of transmission nodes (Transmission Point, referred to as TP) participation and same subscriber equipment (User Equipment, referred to as UE).Fig. 1 is according to the schematic diagram of the CoMP deployment scenario of correlation technique, as shown in Figure 1,3 communities adjacent one another are, Remote Radio Unit (the Remote Radio Head of the 100, community, base station 2 of community 1, referred to as RRH) Remote Radio Unit of 101, community 3 102 shares channel information, the distributed intelligence of UE 103, and carry out combined dispatching based on these information, jointly determine scheduling and/or the beam shaping of UE.Wherein, between base station 100 and Remote

Radio Unit

101 and 102, with optical fiber, be connected.

When using CoMP technology, the signal quality that simultaneously participates in the transmission node of transmission in order to weigh these, 3GPP has introduced channel state information reference signals (Channel-State Information reference Signal, referred to as CSI-RS).In CoMP use scenes, the transmission node number that can jointly participate in transmission is often greater than the transmission node number that UE is used simultaneously, and network terminal need to be selected the transmission node that participates in transmission for common from numerous transmission nodes.Fig. 2 is according to the schematic diagram of each resource collection of CoMP of correlation technique, and as shown in Figure 2, CoMP technology has proposed the concept of several resource collections.Wherein 200 is CoMP resource management set (CoMP Resource Management Set), UE carries out L3(layer3 to the CSI-RS resource in CoMP resource management set 200, layer 3) measure and give network terminal measurement feedback, network terminal can utilize the measurement result of feedback to select CoMP measuring assembly 201; Further, UE carries out L1(layer1 to the resource in CoMP measuring assembly 201, layer 1) measure and measurement result is reported to network terminal in the mode of channel status indication, thereby network terminal can utilize the channel status indication of feedback to select CoMP cooperation set 202; Node in CoMP cooperation set 202 participates in determining scheduling and/or the beam shaping of UE 205 jointly.Here, L3 measurement refers to need to assess and need through relative long period the measurement of layer 3 filtering, and L1 measurement refers to through relative short period assessment and do not need L3 to participate in the measurement of filtering.

CoMP transmission technology is particularly useful for improving the performance requirement of user in the heterogeneous network that Cell Edge User or macrocell and low power nodes form.Along with the movement of UE, the Serving cell of UE will change, and how process the measurement of Serving cell CSI-RS while changing, there is no at present relevant solution.

Below in conjunction with preferred embodiments and drawings, the implementation procedure of above-described embodiment is elaborated.

Embodiment mono-

The present embodiment provides a kind of measurement configuration processing method and subscriber equipment, for solving the measurement of Serving cell CSI-RS while changing, processes.

In implementation process, measuring configuration processing method can comprise: when switching or during RRC connection reconstruction, if switch or RRC connection reconstruction before UE be configured CSI-RS measurement, whether the CSI-RS of UE judgement configuration measures and remains valid in Target cell; If it is no longer valid in Target cell that the CSI-RS of UE judgement configuration measures, UE deletes CSI-RS and measures corresponding measurement sign.

Wherein, to measure the method whether remaining valid in Target cell can be one or more the combination in following method to the CSI-RS of UE judgement configuration:

(1) UE judges whether to occur Serving cell change, if there is Serving cell change, thinks that the CSI-RS of configuration measures in the Target cell after switching or RRC reconstruction no longer valid;

(2) UE is used the frequency (primary frequency) of switching main Serving cell, front source (primary serving cell) and the frequency of the main Serving cell of target after switching to compare, and judges whether frequency changes.If there is change, think that the CSI-RS configuring on the main service frequency in source measures no longer valid in Target cell;

(3) UE is used the frequency (primary frequency) of switching main Serving cell, front source (primary cell) and the frequency of the main Serving cell of target after switching to compare, if less than the Serving cell with the identical frequency of source main Serving cell frequency, think that the CSI-RS of configuration measures in the Target cell after switching no longer valid in the target serving district (comprising primary cell and secondary cell) after switching;

(4) UE judges that the CSI-RS of rrc layer configuration measures corresponding frequency and whether is also present in Serving cell after switching (after switching in the target serving district of UE, frequency identical Serving cell in CSI-RS resource place during the CSI-RS that whether includes the configuration of frequency and Serving cell, source measures), if the CSI-RS of Serving cell, source configuration measures corresponding frequency and is not present in the target serving district after switching, think that the CSI-RS of configuration measures in the Target cell after switching no longer valid (if Serving cell, source has configured CSI-RS measurement on a plurality of frequencies, may occur that part CSI-RS measures effective afterwards in switching, the situation of partial invalidity).

Preferably, if UE side has all configured CSI-RS measurement on a plurality of frequencies before switching, UE judgement validity or the take frequency independent for each CSI-RS measures measured the validity after switching or RRC reconstruction as unit judges CSI-RS.

Preferably, UE, when deletion CSI-RS measures corresponding measurement sign, measures effectively if there is part CSI-RS, and part CSI-RS measures invalid situation; UE can select to delete invalid CSI-RS and measure sign and retain effective CSI-RS measurement sign; Or once UE selects to have invalid CSI-RS to measure, UE deletes all CSI-RS and measures sign.

Preferably, UE, when deletion CSI-RS measures corresponding measurement sign, can also further delete CSI-RS measurement sign corresponding measuring object (measurement object).Or UE, when deletion CSI-RS measures corresponding measurement sign, can also further delete the CSI-RS measurement corresponding measurement report configuration of sign (Report Configuration).

In addition, UE is when deletion CSI-RS measures corresponding measurement sign, can also further judge deleted CSI-RS measure the corresponding measurement report configuration of sign (Report Configuration) have or not be switched or RRC connection reconstruction after still effectively to measure sign associated, if not, delete this measurement report configuration; If had, retain.

Wherein, the CSI-RS measurement of above-mentioned rrc layer is before switching or RRC reconstruction, the CSI-RS measurement of correlation being configured by rrc layer.It is including but not limited to the CSI-RS measurement of correlation with Types Below: the CSI-RS measurement of correlation of Event triggered, the CSI-RS measurement of correlation periodically reporting and/or other have used the measurement of CSI-RS measurement result in measurement result or measurement event trigger condition evaluation process.

Preferably, UE deletes that CSI-RS measures that operating in of corresponding measurement sign switched or RRC process of reconstruction is carried out after completing; Or receiving that switching (RRCConnectionReconfiguration) or RRC carry out after rebuilding (RRCConnectionReestablishment) order.

Embodiment bis-

In LTE system, for meeting, connect mobility control (Connection Mobility Control, referred to as CMC), interference coordination (Inter-cell Interference Coordination, the RRM demand such as ICIC), eNB can control for Radio Resource the UE configuration pin of (Radio Resource Control, referred to as RRC) connection status the L3 of the specific cell reference signals in community (Cell Reference Signal, referred to as CRS) resource is measured.Introducing after CoMP technology, is assisted Selection CoMP measuring assembly, and base station can be measured the L3 of CSI-RS resource for UE configuration pin again, i.e. the measurement of CoMP resource management set.Particularly, the L3 measuring process of CSI-RS resource is: eNB is that UE configuration CSI-RS measures, and UE carries out the measurement of CSI-RS and assesses reporting measurement reports.Wherein, eNB is that UE configuration CSI-RS measurement comprises:

1, measuring object (Measurement Object, referred to as MO) configuration: eNB is that UE configuration needs the CSI-RS resource of measuring.

During concrete configuration, it is object that eNB can be take frequency (frequency), and all CSI-RS resource distributions that need UE to measure in this frequency are sent to UE in same measuring object.Such as, eNB judgement needs UE to measure 4 the CSI-RS resources (being respectively 4 CSI-RS resources on TP) on service frequency f1, and eNB can configure following MO:

{

What f1(configured is the absolute carrier frequency number of frequency f 1)

CSI-RS the Resources list { comprises CSI-RS resource 1, CSI-RS resource 2, CSI-RS resource 3, CSI-RS resource 4}

}

During concrete configuration, eNB also can directly be take CSI-RS resource as object allocating and measuring object.Such as, eNB judgement needs UE to measure 4 the CSI-RS resources (being respectively 4 CSI-RS resources on TP) on service frequency f1, and eNB can configure following MO:

MO1:CSI-RS resource 1

MO2:CSI-RS resource 2

MO3:CSI-RS resource 3

MO4:CSI-RS resource 4

No matter be above-mentioned which kind of configuration mode, during eNB allocating and measuring object, can be measuring object sign of each measuring object configuration, be a MeasObjectId of each MO configuration.

Wherein, the concrete configuration of CSI-RS resource can be including but not limited to: the configuration of antenna port number; Determine the time domain (symbol) of concrete CSI-RS resource in subframe and the resource distribution (resourceConfig) of frequency domain position; Determine the sub-frame configuration (subframeConfig) of cycle and subframe skew etc.

2, report configuration (Reporting Configuration, referred to as RC): the criterion that configuration report triggers (such as, periodic triggers, Event triggered etc.) and other parameters, if Event triggered criterion, the event type that configuration event triggers, trigger parameter etc., if periodic triggers, the triggering type that configuration cycle property triggers, report cycle etc.ENB can configure a plurality of RC configurations for UE, and in order to distinguish different RC configurations, eNB can be a RC configuration identifier ReportConfigId of each RC configuration configuration.

3, measure sign (Measurement Identity/MeasId, referred to as MID) configuration: eNB can configure a plurality of MID for UE.ENB configures the associated MO configuration of a MID and a RC configuration, configures the associated MeasObjectId of a MeasId and ReportConfigId, thus unique definite each measurement task.

UE receives that the L3 of CSI-RS measures after configuration, UE is according to the associated MO configuration of MeasId and RC configuration, the measuring object configuring in the associated MO configuration of each MeasId is measured, and how associated RC configuration assessment judgement reports the measurement result on each measuring object according to each MeasId.

CoMP transmission technology is particularly useful for improving the performance requirement of user in the heterogeneous network that Cell Edge User or macrocell and low power nodes form, movement along with UE, the Serving cell of UE likely changes, such as, eNB is switched to another Serving cell UE from a Serving cell, or UE Radio Link Failure (Radio Link Failure, referred to as RLF) occurs afterwards in Serving cell, source, UE carries out RRC connection reconstruction, is reconstructed into another Serving cell.In CoMP technology, CSI-RS resource is the specific resource of UE, be CSI-RS its pseudorandom initial value and Physical Cell Identifier (Physical Cell Identity when design, referred to as PCI) there is no a binding relationship, but determine by configurable virtual subdistrict sign, in addition, the configurations such as the resourceConfig in CSI-RS resource distribution and subframeConfig, different TP also may have different configurations.

Therefore, when Serving cell changes, Target cell probably cannot know that UE is in the CSI-RS of cell-of-origin resource distribution on the one hand, even if the CSI-RS resource distribution of LiaoUEYuan community is known in Target cell on the other hand, but, Target cell is for frequency shift, or the change of other scheduling resources and disturbed condition, probably has to need to change to be configured the CSI-RS resource to UE.That is to say, when Serving cell changes, the CSI-RS resource that Serving cell, source configures to UE probably lost efficacy.

For reduce Serving cell while changing the unnecessary CSI-RS of subscriber equipment measure, thereby the power consumption of saving subscriber equipment and further reduces the space interface signaling expense of Serving cell while changing, the present embodiment proposes a kind of measurement configuration processing method and subscriber equipment.

Measurement configuration processing method in the present embodiment comprises: when Serving cell changes, UE deletes the measurement sign that CSI-RS resource L3 measures configuration.

Preferably, when Serving cell changes, UE deletes the measurement sign of CSI-RS resource L3 measurement configuration and deletes described measurement and identifies associated measuring object configuration.

Preferably, when Serving cell changes, UE deletion CSI-RS resource L3 measures the measurement sign of configuration and deletes described measurement and identifies associated measuring object configuration and report configuration.

Preferably, when Serving cell changes, if do not configure CoMP measuring assembly (CoMP measurement set) in switching command, UE deletes the CoMP measurement set that Serving cell, source configures.

In implementation process, the Serving cell of UE changes and can comprise: UE is switched to target serving district from Serving cell, source, or RLF occurs in Serving cell, source UE, and UE RRC connection reconstruction is to target serving district.
