Patent ID: 8625526

Claim:
A method for obtaining a synchronization signal in a wireless communication system, the method comprising: dividing a full frequency band into a synchronization band for transmission of the synchronization signal and a usual band for transmission of multimedia broadcast multicast service (MBMS) data, the synchronization band and the usual band having the same structure in a time domain by comprising the same number of orthogonal frequency division multiplexing (OFDM) symbols having the same length, the synchronization band the usual band being multiplexed using a frequency division multiplexing (FDM) scheme; searching for a primary synchronization signal (PSS) for a dedicated MBMS in the synchronization band, a length of a Zadoff-Chu (ZC) sequence used as the PSS for the dedicated MBMS being two times higher than a length of a ZC sequence used as a PSS for a unicast, the ZC sequence used as the PSS for the dedicated MBMS; and detecting the PSS for the dedicated MBMS through the synchronization band.
