In specific embodiments of the invention, described first kind carrier type refers to traditional carrier type of the prior art; The follow-up Equations of The Second Kind carrier type of mentioning refers to the new carrier type proposing in LTE Rel-11 standard.
In the frame format of existing LTE TDD, the 3rd OFDM that PSS is mapped in subframe 1 and subframe 6 meets; SSS is mapped on last OFDM symbol of subframe 0 and subframe 5.Because the distance between UE and the eNB of different adjacent cells is different, therefore UE receive time of PSS and SSS that the eNB of different adjacent cells sends may be different, therefore, in specific embodiments of the invention, need to set in advance a time window, to ensure that UE can receive PSS and the SSS of the eNB transmission of different adjacent cells.In preferred embodiment of the present invention, described in the length of the time window that sets in advance can be 10 milliseconds.
According to LTE Rel-8 standard regulation, PSS uses Zadoff-Chu sequence, has 3 PSS sequences, the ID in the corresponding physical-layer cell group of each PSS sequence:
value is the integer in 0～2; SSS uses m sequence, has 168 sequences, the corresponding physical-layer cell group number of each SSS sequence:
