Patent ID: 8229052

Claim:
A method for transmitting, by a transmitter, a Secondary Synchronization CHannel (S-SCH) in a communication system, the method comprising: determining a subcarrier set comprising subcarriers for use in mapping of a sequence to be transmitted using the equation: SSCHCarrierSet n = n + 3 · k + 40 · N SSCH 144 + ⌊ 2 · k N SSCH ⌋ wherein, SSCHCarrierSet n denotes an n -th subcarrier set, n denotes an index of a subcarrier set representing a segment ID and has a value of ‘0’, ‘1’, or ‘2’, k denotes a running index having a value of ‘0’ to ‘N SSCH -1’ for each FFT sizes, and N SSCH denotes the number of subcarriers allocated for S-SCH and has a value of ‘144’ at 512-FFT size, ‘288’ at 1024-FFT size, and ‘576’ at 2048-FFT size, respectively; and transmitting the sequence.
