Claim:
1. A method for transmitting a synchronous channel by a base station in a communication system, comprising: generating synchronous signals to be transmitted on a primary synchronous channel (P-SCH) and a secondary synchronous channel (S-SCH); mapping the synchronous signals except for reference signals to first orthogonal frequency division multiplexing (OFDM) symbols to form the P-SCH and the S-SCH; mapping the reference signals to second OFDM symbols different from the first OFDM symbols, the reference signals including a user-specific demodulation reference signal (DMRS), a channel state indication reference signal (CSI-RS) and a tracking reference signal (TRS); and transmitting the mapped synchronous signals on the P-SCH and the S-SCH.
