Embodiment
The inventor notices in the invention process: in LTE R8 (version 8), in order to support UE moving in network, network side needs in time according to its latest position it to be switched under the only eNB, this process is traditional handoff procedure, before handoff procedure, eNB need control UE this sub-district and adjacent sub-district are measured, and the measurement report that sends according to UE carries out switch decision (promptly according to factor select target sub-districts such as signal strength signal intensities) then.The measurement of RSRP/RSRQ (reference signal received power/reference signal received quality, Reference Signal Received Power/Reference Signal Received Quality) has 2 steps:
1) cell acquisition is undertaken by the synchronizing channel (P-SCH/S-SCH:Primary Synchronization Channel/Secondary Synchronization Channel, primary synchronization channel/auxiliary synchronization channel) that detects this sub-district;
2) signal measurement measures by the CRS (cell specific Reference signal, specific cell reference signal) to this sub-district.
For this sub-district, before measurement, UE has finished the acquisition procedure to this sub-district, and follow-up needs are measured CRS and got final product; And, must carry out 2 processes of cell acquisition and cell measurement successively to adjacent sub-district.
There is multiple deployment scenario in RN, wherein a kind ofly be called mobile RN scene, this moment, RN was transportable, such as at bus or mobile RN of train deploy, it can provide service for each UE in the compartment, this moment, RN and being connected can think staticly relatively between the RN-UE on it, and this scene is also referred to as the group and moves (group mobility).In order to support the mobility of RN, RN in time need be switched to suitable DeNB equally, report+switch this mobility management mechanism so need equally similarly to measure.
Yet according to present standard, RN can't realize adjacent sub-district is measured.From the angle of RN, its frame structure can be divided into 2 parts:
1, RN monitors the moment of DeNB, and according to existing standard, this part subframe always is positioned in MBSFN (Multimedia Broadcast multicast service Single Frequency Network, the Multicast Broadcast Single Frequency Network) subframe.
2, RN moment that RN-UE is served.
In the moment of RN at monitoring DeNB, owing to have CRS in backhaul (back haul link) subframe, therefore RN can obtain the signal strength measurement of this sub-district (donor cell), but because the MBSFN subframe does not comprise the subframe 0 at P-SCH/S-SCH place and subframe 5 (because according to release 8 standards, subframe 0 and subframe 5 must be used for the transmission of system information, so MBSFN can not use this 2 subframes), RN can't carry out the cell acquisition process to the adjacent sub-district of donor cell, therefore can't finish search and measurement to adjacent sub-district.If RN does not consider the restriction of MBSFN, (not merely a bit of time after the RN start carries out for adjacent cell acquisition and measuring process to carry out adjacent cell acquisition in subframe 0 and subframe 5, but after the RN start, carry out all the time), this will influence the transmission means of the system information of RN oneself so, directly the result is exactly that the RN-UE that is connected on it can't monitoring system broadcast, and causes RN to serve for UE.
Based on this, provide mobile RN to measure the technical scheme of problem in the embodiment of the invention, basic inventive concept of the present invention is: utilize RN and RN-UE between the two the position relatively more fixing and near these characteristics, allow RN-UE replace RN to carry out the measurement of adjacent sub-district.Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
Fig. 2 is a measurement result report method implementing procedure schematic diagram, and as shown in the figure, the reporting measurement result can comprise the steps:
The UE that step 201, RN indication are connected to RN measures the adjacent sub-district of donor cell;
In the enforcement, there is no inevitable execution sequential relationship between step 201 and the step 202.
In the enforcement, RN can control connection measures donor cell and/or its adjacent sub-district to the UE of RN, and the adjacent cell measurement result who utilizes RN-UE to send then realizes the switch decision to RN.
In the enforcement, can further include:
RN is to the UE configuration information of adjacent cells that is connected to RN;
