Description
Technical field
The present invention relates to communication technical field, more specifically, relate to a kind of method of channel wireless radio multi communication system nearby region measurement.
Background technology
In the channel wireless radio multi communication system, whole band resource is divided into 40 subbands, comprising 3 synchronous subbands and 37 professional subbands, belongs to respectively 3 different bunches.Subband is mainly used in Cell searching, synchronous and broadcast reception synchronously, and professional subband is mainly used in the up-downgoing transfer of data.Each bunch comprises a synchronous subband and several professional subbands.
UE obtains the residential quarter blockage information, perhaps after the downlink synchronization failure, needs to consider to switch the residential quarter preferably to other signal qualitys, and the foundation of switching is exactly the result of nearby region measurement.
UE can reside in any one bunch in 3 bunches of the residential quarters.Referring to accompanying drawing 1, present nearby region measurement process may further comprise the steps:
After step 101, UE receive nearby region measurement indication, switch to synchronous subband 1 from the professional subband of work at present.
Need to carry out first the adjacent area before the nearby region measurement synchronous.UE receives the uplink/downlink antenna data at the synchronization frame (S in the accompanying drawing 2) of synchronous subband 1, is used for the calculating of Timing Synchronization position.In the accompanying drawing 2, S represents synchronization frame, and P represents broadcast frame, D representative data frame.If be 35km according to radius of society, the sample rate of per second 128k is calculated, the largest interval of adjacent cell Timing Synchronization position and this cell timing sync bit is 30 sampled points, in order to calculate Timing Synchronization position, adjacent area, receive the uplink/downlink antenna data than normal 925 sampled points, have more 60 sampled points.60 sampled points comprise 30 sampled points before normal 925 sampled points, and 30 sampled points after normal 925 sampled points, namely receive 985 sampled points of uplink/downlink antenna data.
The Timing Synchronization position of step 103, calculating adjacent area, Reference Signal Received Power (RSRP) and the Reference Signal Received Quality (RSRQ) of measurement adjacent area.
In the channel wireless radio multi communication system, need to measure RSRP and the RSRQ of 3 adjacent areas, so calculate respectively the Timing Synchronization position of 3 adjacent areas at every turn.Finish subband at the N frame and switch, receive 985 uplink/downlink antenna data at the N+2 frame, calculate the Timing Synchronization position of 3 adjacent areas.Calculating the Timing Synchronization position is prior art.
In the Timing Synchronization position of N+3 frame (the P frame in the accompanying drawing 2) according to adjacent area 1, adjust the frame head position, receive the downlink broadcast data, measure RSRP, the RSRQ of adjacent area 1.
In the Timing Synchronization position of N+5 frame according to adjacent area 2, adjust the frame head position, receive the downlink broadcast data, measure RSRP, the RSRQ of adjacent area 2.
In the Timing Synchronization position of N+7 frame according to adjacent area 3, adjust the frame head position, receive the downlink broadcast data, measure RSRP, the RSRQ of adjacent area 3.
After finishing the Timing Synchronization position measurement of synchronous subband 1, switch to synchronous subband 2 at the N+7 frame, finish respectively the measurement of synchronous subband 2 at N+9, N+11, N+13, measuring process is with subband 1 is similar synchronously.
After finishing the Timing Synchronization position measurement of synchronous subband 2, switch to synchronous subband 3 at the N+13 frame, finish respectively the measurement of synchronous subband 3 at N+15, N+17, N+19, measuring process is with subband 1 and 2 is similar synchronously.
Finish after the measurement of 3 synchronous subbands, UE switches back original professional subband, proceeds original transfer of data, and nearby region measurement finishes.
From top nearby region measurement process, finish 3 adjacent areas and need 20 radio frames in the measurement of 3 synchronous subbands, because professional subband is inoperable in measuring process, so above-mentioned measurement scheme has not only increased the measurement time delay, has also affected normal transfer of data.
