Abstract:
1. A method of transmitting a synchronization signal for cell search in an Orthogonal Frequency Division Multiplexing (OFDM) based cellular communications system, comprising: transmitting a sequence constituting a Primary Synchronization CHannel (P-SCH) over first symbols mapped to a first set of subcarriers by applying a frequency reuse factor with a value of 1 in at least one first OFDM symbol interval; transmitting a sequence constituting a Secondary Synchronization CHannel (S-SCH) over second symbols mapped to a second set of subcarriers from among the first set of subcarriers by applying a frequency reuse factor with a value greater than 1 in at least one second OFDM symbol interval; and transmitting sequences constituting channels other than said P-SCH and S-SCH in OFDM symbol intervals other than said first and second OFDM symbols.
