Description

INFORMATION DETECTION METHOD AND USER EQUIPMENT
The detection method and user equipment technical field of a kind of information
The present invention relates to the detection method and user equipment of the communications field, more particularly to a kind of information.
Background technology
In LTE (Long Term Evolution, Long Term Evolution）In system, master sync signal is first monitored after user equipment (User Equipment, UE) start（Primary Synchronization Signal,) and auxiliary synchronous signals (Secondary Synchronization Signal PSS, SSS), obtain the information such as coarse frequency synchronization, cell ID, frame timing, then Physical Broadcast Channel (Physical Broadcast Channel are detected, PBCH), the main information block that PBCH is carried is obtained（ Master Information Block, MIB ).UE monitors Physical Downlink Control Channel according to the MIB of acquisition（Physical Downlink Control Channel, PDCCH), another ll symbols (System Information- Radio Network Temporary Identifier are known temporarily with system information wireless network, SI-RNTI) to PDCCH CRC (Cyclic Redundancy Check, CRC) descrambled, by detecting that PDCCH obtains schedule system information block（System Information Block, SIB) Downlink Control Information（Downlink Control Information, DCI), detect Physical Downlink Shared Channel further according to the DCI（Physical Downlink Shared Channel, PDSCH) so as to obtain SIB.Afterwards, UE just can set up wireless heterogeneous networks by random access procedure and base station（Radio Resource Control, RRC) connection, after the completion of RRC connections foundation, UE can just carry out the interaction of up-downgoing business datum with base station.
PBCH comprising 4 can with the part of self-demarking code, UE can by any of which one the MIB of PBCH carryings can be obtained with the detection of the part of self-demarking code.In the prior art, the coverage enhancement method of PBCH a kind of is that PBCH can be the integer more than 4 with the part of self-demarking code, X comprising X, and this PBCH is called enhanced PBCH.PDCCH coverage enhancement method is included the aggregation level for being increased PDCCH using overall compact DCI and will Identical DCI repeats transmission etc. in multiple subframes.SIB coverage enhancement method includes defining repetition transmission of the new sub-frame resources for SIB.Wherein, the DCI's that sends each time or SIB all can be with self-demarking code when repeating to send.
UE when being detected to PBCH or enhanced PBCH, can detect it is multiple it is different can be with the part of self-demarking code, then to being merged from the different Soft Inform ations come that can be demodulated with the part of self-demarking code, so as to improve the probability that MIB is correctly detected.Likewise, for the DCI or SIB that repeat to send detection, UE can also detect the part of multiple repetitions, be merged to demodulating the Soft Inform ation come from the part of multiple repetitions, so as to improve the probability that DCI or SIB are correctly detected.Path loss for receiving or sending signal experience then needs more merging number of times, to meet the performance requirement of infomation detection than larger UE.But UE carry out MIB detection, with the addition of SI-RNTI scrambling CRC DCI detection or obtain (the System Information Block Type 2 of system information block type 2, when SIB detection is carried out before SIB2), the channel circumstance residing for itself is not known, can not just know the size of path loss corresponding with channel circumstance yet.
By taking MIB as an example, UE is not due to knowing the channel circumstance residing for itself, so as to which Zhi Ding is in worst channel circumstance, detection it is all can self-demarking code part, i.e. enhanced PBCH X can self-demarking code part, and carry out X- to demodulating the Soft Inform ation come from described X part and merge for 1 time；Or, UE pairs can carry out blind Detecting with the part of self-demarking code, and blind trial merges number of times.Specifically, UE first detects PBCH according to existing PBCH detection method, if PBCH CRC check mistake, UE, which fails, obtains MIB, then starts to detect enhanced PBCH.When detecting enhanced PBCH for the first time, detection Y can be with the part of self-demarking code, next Soft Inform ation will be demodulated and do 1 merging of Y-, if CRC check mistake, then successively increase detection can self-demarking code part number and merge number of times, until CRC check success or detect can self-demarking code part number be equal to X, wherein, Y is a fixed numerical value.DCI and SIB detection is similar with MIB detection.
As can be seen here, UE is in the case where knowing the channel circumstance residing for itself, can blindness information is detected, may cause to extend during detection, the problem of power consumption is big, detection complexity is high.
The content of the invention Embodiments of the invention provide the detection method and user equipment of a kind of information, can solve the problem that UE in the case of channel circumstance where not knowing itself, extension during detection, the problem of power consumption is big, detection complexity is high.
