Specific embodiment
It is proposed in 3GPP Rel-14 discussion, UE realizes, the composition of synchronization signal synchronous with base station by synchronization signal
Including at least primary synchronization signal and secondary synchronization signal.Meanwhile considering in the form of synchronization signal block in 3GPP Rel-14 discussion
Synchronization signal is presented, and considers and introduces the mode of beam scanning (Beam Sweeping) in a wireless communication system to each
Wave beam (beam) scans in the time domain, and this scanning can cause on each wave beam in synchronization signal block primary synchronization signal and
The beam scanning of secondary synchronization signal, and then will cause UE obscuring for synchronization signal block timing, i.e. UE can be to synchronization signal block
The position judgement of serial number and synchronization signal block in system sequence generates uncertain.
In other words, when UE detects a primary synchronization signal or secondary synchronization signal, it can not judge that the synchronization is believed
The serial number of synchronization signal block belonging to number can not also judge the corresponding position of the synchronization signal block in system sequence, this
It is because not can determine that relative position of the synchronization signal block in timing on different beams is identical.For example, wave beam a
The primary synchronization signal of primary synchronization signal wave beam b in some system-frame perhaps the symbol m of subframe is in some system-frame or subframe
Symbol n on, if m and be not equal to n when, after UE detects primary synchronization signal, UE can not judge the primary synchronization signal
Specifically on symbol m or on symbol n, and the position of symbol m and symbol n in system sequence is not identical, thus can band
Carry out the uncertainty of position judgement of the UE to synchronization signal block in system sequence.
The uncertainty of position judgement for UE to synchronization signal block in system sequence, currently, new by design

The position tool of information, the serial number of synchronization signal block and the first synchronization signal sub-block and the second synchronization signal sub-block in system sequence
Have preset mapping relations, therefore for user equipment, can be calculated first and second synchronization signal sub-block when
After the opposite offset in domain, and then confirm first and second the described position of synchronization signal sub-block in system sequence, and complete with
The time synchronization of base station designs the new synchronization signal of new synchronous signal sequence or introducing without additionally increasing, therefore can drop

Set that synchronizing cycle is corresponding with other length, the specific length of synchronizing cycle is not construed as limiting protection scope of the present invention.
Below with reference to Fig. 2, the method is discussed in detail step by step:
Step S21: the first synchronization signal Sub-Block Sequence and the second synchronization signal Sub-Block Sequence are received.
In specific implementation, the first synchronization signal sub-block and the second synchronization signal sub-block may include following any two
Kind: primary synchronization signal, secondary synchronization signal and broadcast singal.It, can also be with that is, those skilled in the art are according to actual needs

First synchronization signal sub-block is broadcast singal, and it is primary synchronization signal that the second synchronization signal sub-block is arranged simultaneously.
Step S22: according to the reception timing of the first synchronization signal Sub-Block Sequence and the second synchronization signal Sub-Block Sequence,
The time domain being calculated between each first synchronization signal sub-block and corresponding second synchronization signal sub-block received is opposite to be deviated.
It in specific implementation, can be according to the first synchronization signal Sub-Block Sequence and the second synchronization signal Sub-Block Sequence
Timing is received, the time domain between each first synchronization signal sub-block and corresponding second synchronization signal sub-block received is calculated
Opposite offset.For example it is sequentially received in the 5th symbol and the 6th symbol synchronous including the first synchronization signal sub-block 1 and first
First synchronization signal Sub-Block Sequence of signal sub-block 2 is sequentially received synchronous including second in the 7th symbol and the 8th symbol
The synchronous letter of first received is calculated in second synchronization signal Sub-Block Sequence of signal sub-block 2 and the second synchronization signal sub-block 1
The opposite offset of time domain between work song block 1 and the second synchronization signal sub-block 1 is 3 symbols, and it is same that first received is calculated
Walking the opposite offset of the time domain between signal sub-block 2 and the second synchronization signal sub-block 2 is 1 symbol.
Step S23: according between each first synchronization signal sub-block and corresponding second synchronization signal sub-block received

In position.
In specific implementation, about according to each first synchronization signal sub-block received and corresponding second synchronization signal
The opposite offset of time domain between block, confirms that each first synchronization signal sub-block received and corresponding second synchronization signal sub-block exist

SSS between time domain it is opposite deviate, and then based on the synchronization signal block detected and primary synchronization signal and secondary synchronization signal
Between time domain opposite deviate, it can be determined that obtain position and serial number of the synchronization signal block detected in system sequence.
With reference to Fig. 3, in the beam scanning of 3 wave beams composition, corresponding auxiliary of primary synchronization signal can be calculated in UE
The opposite offset of time domain between synchronization signal is toff1, so UE according to preset mapping relations it is found that time domain is opposite deviates
toffThe corresponding wave beam of 1 instruction is identified as beam1, and corresponding synchronization signal block serial number synchronization signal block 1 indicates corresponding same
Timing position of the PSS1 in system sequence in step block 1 is that the SSS1 in t1 and corresponding synchronization signal block 1 is being
Timing position in timing of uniting is t1'。
In specific implementation, when detecting the synchronization signal block 2 based on wave beam 2 in T synchronizing cycle as UE, UE can be calculated
Show that opposite deviate of the time domain between primary synchronization signal and secondary synchronization signal is toff2, toffThe corresponding wave beam of 2 instructions is identified as
Beam2 indicates corresponding synchronization signal block serial number synchronization signal block 2, indicates that the PSS2 in corresponding synchronization signal block is being

t2'。
In specific implementation, when detecting the synchronization signal block 3 based on wave beam 3 in T synchronizing cycle as UE, UE can be calculated
Show that opposite deviate of the time domain between primary synchronization signal and secondary synchronization signal is toff3, toffThe corresponding wave beam of 3 instructions is identified as
Beam3 indicates corresponding synchronization signal block serial number synchronization signal block 3, indicates that the PSS3 in corresponding synchronization signal block is being

t3'。
To sum up, the embodiment of the present invention is by the way that it is suitable to be arranged different beam scannings in the communication system using beam scanning
Sequence, therefore opposite time domain deviant, Jin Erli can be generated between primary synchronization signal and secondary synchronization signal inside synchronization signal block
With the opposite time domain deviant, UE can be allowed to obtain position and serial number of the synchronization signal block detected in system sequence,
And then it can be uncertain to avoid time synchronization bring of the beam scanning to base station and UE.Meanwhile it being mentioned in the embodiment of the present invention
Method out indicates on different beams compared to being designed by new synchronous signal sequence or increasing new synchronization signal
