Description
Technical field
The present invention relates to mobile communication technology field, more particularly to a kind of infomation detection and the method and device of transmission.
Background technology
With the development of the communication technology, LTE (Long Term Evolution, Long Term Evolution) system is due to improvement
The performance of Cell Edge User, it is particularly important the advantages of improve cell capacity, reduce Time Delay of Systems.In LTE system,
In order to ensure the mobility performance of UE (User Equipment, user equipment), to accomplish that suitable cell reselection or cell are cut
Change, UE will carry out the measurement in terms of cell RRM (Radio Resource Management, RRM), such as, and ginseng
The RRM measurements of signal reception power are examined, or, RRM measurements of Reference Signal Received Quality etc..Therefore, the mobile management of RRM
Function is an important component in LTE system.
In the prior art, in traditional homogeneous network, the UE in connected state carries out the specific execution of cell RRM measurements
Process is as follows:
Step a:UE indicates to start RRM measurements according to eNB (Evolved NodeB, base station);
Step b:UE passes through PSS (Primary Synchronization Signal, master sync signal) and SSS
(Secondary Synchronization Signal, auxiliary synchronous signals) determines the cell ID of cell;
Step c:After UE determines cell ID, the CRS (Cell- that UE is sent using cell corresponding with cell ID
Specific Reference Signal, cell specific reference signal) RRM measurements are carried out, and corresponding measurement result is reported
To eNB;
Step d:UE is switched over according to the instruction of eNB, wherein, measurement result that eNB is reported according to UE decides whether
Allow the UE to do cell to switch.
Be can be seen that in homogeneous network from above-mentioned implementation procedure, UE by detect eNB send PSS and SSS, with eNB
Synchronize, and determine PCI (Physical Cell Indicator, Physical Cell Identifier), wherein, 3 sequences of PSS offers,
SSS provides 168 kinds of combined sequences altogether by the combination of two short sequences, therefore, 504 cell marks can be provided in the prior art
Know (i.e. 504 kinds PCI).
In existing LTE system, the cycle that base station sends PSS and SSS is all 5ms, and transmission each time is taken in carrier wave
2 OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency in 6 Resource Block of the heart
Multiplexing) symbol, and base station, when CRS is sent, each subframe is required for Whole frequency band to send, and typically constitutes from 1 the 2 of Resource Block
2 or 4 Resource Units in OFDM symbol, in existing LTE system in a Resource Block reference signal resource location such as Figure 1A
It is shown.
With the development of LTE technologies, heterogeneous network also gradually rises, and the Main Patterns of heterogeneous network are, grand small at one
The substantial amounts of Microcell of deployment or picocell (Pico cell) in area (Macro cell), Macro cell and Pico cell can
Disposed with using identical frequency, it would however also be possible to employ different frequencies is disposed (in the prior art based on this kind of pattern), wherein,
Macro cell are mainly used in providing the service of covering and real-time data service, and Pico cell are mainly used in providing two-forty
The service of data service.In heterogeneous network, UE before RRM measurements are carried out, when determining cell ID, if according further to PSS,
SSS determines cell ID, can there is following defect:
Because the Pico cell for disposing in the prior art are than comparatively dense, and the PSS and SSS transmission cycles are shorter, therefore, deposit
Larger situation is disturbed when UE receives PSS and SSS, when causing UE to determine cell ID according to PSS, SSS, more long, effect is taken
The problem that rate is relatively low and accuracy is poor, simultaneously as being sent out in 2 OFDM symbols in 6 Resource Block of carrier center
PSS or SSS is sent, the probability for sending time interval resource overlap shared during PSS or SSS is larger, therefore, also result in UE and exist
When receiving PSS and SSS, there is a problem of that interference is larger, and then when causing UE to determine cell ID according to PSS, SSS, there is consumption
When more long, the poor problem of less efficient and accuracy.
The content of the invention
