METHOD AND APPARATUS FOR TRANSMITTING SYNCHRONIZATION SIGNALS IN AN OFDM BASED CELLULAR COMMUNICATIONS SYSTEM |
摘要 |
Provided is a method and apparatus for transmitting a synchronization signal for cell search in an Orthogonal Frequency Division Multiplexing (OFDM) communications system. The method includes acquiring Primary Synchronization CHannel (P-SCH) sequence and Secondary Synchronization CHannel (S-SCH) sequence; mapping the P-SCH sequence and the S-SCH sequence onto subcarriers; generating OFDM symbols including the P-SCH sequence and the S-SCH sequence mapped onto subcarriers; and transmitting the OFDM symbols, wherein a frame comprising a plurality of OFDM symbols, a part of the plurality of OFDM symbols in the frame is used for transmitting Synchronization CHannel (SCH) comprising P-SCH and S-SCH, and wherein the P-SCH and the S-SCH are mapped to adjacent OFDM symbols and the S-SCH is mapped to subcarriers with a predetermined interval in a frequency domain within an OFDM symbol.
