For mobility and the measurement of scheduling and measurement report configuration.

Here also of interest is with further version (such as, the LTE of the following IMTA system 3GPP LTE as target Rel-10), herein for conveniently referred to as LTE-senior (LTE-A).It is referred to 3GPP in this regard TR36.913,V9.0.0(2009-12),3rd Generation Partnership Project;Technical Specification Group Radio Access Network;Requirements for Further Advancements for EUTRA(LTE-Advanced)(Release9).Can also be with reference to 3GPP TR36.912V9.2.0 (2010-03)Technical Report3rd Generation Partnership Project; Technical Specification Group Radio Access Network;Feasibility study for Further Advancements for EUTRA(LTE-Advanced)(Release9)。

The target of LTE-A is made by more high data rate and more low delay, provides, with the cost reduced, the clothes being obviously enhanced Business.LTE-A relates to extension and optimizes 3GPP LTE Rel-8 radio access technologies to provide higher number under lower cost According to speed.LTE-A by be a kind of meet require for senior for IMT-ITU-R and keep and LTE Rel-8 backwards compatibility More optimization radio system.

One aspect of LTE and LTE-A determines that the position of UE.In this regard can be such as with reference to 3GPP TS36.305V9.3.0(2010-06)Technical Specification3rd Generation Partnership Project；Technical Specification Group Radio Access Network；Evolved Universal Terrestrial Radio Access Network(E-UTRAN)；Stage2functional specification of User Equipment(UE)positioning in E-UTRAN(Release9)；3GPP TS36.355V9.2.1(2010- 06)Technical Specification3rd Generation Partnership Project；Technical Specification Group Radio Access Network；Evolved Universal Terrestrial Radio Access(E-UTRA)；LTE Positioning Protocol (LPP) (Release9) and 3GPP TS36.455V9.3.0 (2010-09)Technical Specification3rd Generation Partnership Project；Technical Specification Group Radio Access Network；Evolved Universal Terrestrial Radio Access(E-UTRA)；LTE Positioning Protocol A(LPPa)(Release9).

With reference to Fig. 3, evolution Serving Mobile Location Center (E-SMLC) uses LTE location protocol (LPP) to communicate with UE.Logical Cross LPP, E-SMLC and to the information of the community that UE provides anticipated UE to attempt measuring and OTDOA measurement report can be received from UE. E-SMLC is responsible for measuring based on UE calculating with the priori in geographical position, community and the relative final position sending timing difference thereof.

Fig. 4 describe for the control planar network framework of LPP agreement and LPP protocol Data Unit (PDU) via MME and The delivery (controlling plane signaling flow) of eNB.Fig. 5 illustrates for handing over via MME and eNB LPP-PDU between UE and E-SMLC The control plane protocol stack changed.

In figures 3,4 and 5, server (E-SMLC) provides the list of potential neighbor cell that is to be searched and that measure to UE. Then UE measures and reports the OTDOA for the neighbor cell detected.Inspection is also needed in addition to Serving cell (service eNB) Survey at least two neighbor cell to calculate for position (triangulation).

Definition UE OTDOA is measured as reference signal time difference (RSTD) and measures.With frequency neighbor cell RSTD measure without From Serving cell any alternately, such UE can perform measure and do not affect the communication link with Serving cell.

But, going wrong in following LTE Rel-9 extends, this expanded definition RSTD is measured to apply also for alien frequencies adjacent Occupy community.Produced problem relates to unless Serving cell explicitly ensures that to UE measurement opportunity (measurement gap) is surveyed at these Amount opportunity (measurement gap) period allows it its receptor to be tuned to another frequency at once for measuring purpose then Do not estimate that UE can measure transmission the fact of the frequency in addition to Serving cell frequency.

Can be such as with reference to 3GPP TS36.331V9.3.0 (2010-06) Technical about measuring gap Specification3rd Generation Partnership Project；Technical Specification Group Radio Access Network；Evolved Universal Terrestrial Radio Access(E-UTRA)；Radio Resource Control(RRC)；The 5.5.2.9 joint of Protocol specification (Release9) " Measurement gap configuration " and 6.3.5 saves " Measurement information elements ", Such as MeasConfig cell (page 178) and MeasGapConfig cell (page 179).

As sayed in 5.5.2.9 joint:

UE should:

1 > if measGapConfig is set to ' setup':

2 > if having arranged measurement gap configuration, then gap configuration is measured in release；

2 > arranging the measurement gap configuration of measGapConfig instruction according to the gapOffset received, begins in the most each gap In the SFN and the subframe that meet following condition:

SFN mod T=FLOOR(gapOffset/10)；

Subframe=gapOffset mod10；

Wherein T=MGRP/10 as defined in TS36.133；

1 > otherwise:

2 > gap configuration is measured in release.

According to the standard of current version 9, Serving cell there is no telling E-SMLC, and to have requested that UE performs for OTDOA fixed The alien frequencies RSTD of position measures, and therefore controls the eNB of Serving cell and can not configure as required and must measure gap so that UE can Perform the measurement of request.Therefore the eNB controlling Serving cell is forced allocating and measuring gap always, and this wastes system resource.
