Apparatus and method for transmitting a sub-channel signal in a communication system using an orthogonal frequency division multiple access scheme

摘要

Methods of transmitting an receiving symbols by a Mobile Subscriber Station (MSS) and a Base Station (BS) are provided. The method for receiving symbols by the MSS includes receiving symbols from the BS, wherein the symbols are mapped onto data sub-carriers using a sequence, wherein the sequence includes result values, the result values being generated by applying, to a basic sequence, an offset and a number of cyclic shifting, the basic sequence having a length identical to the number of data sub-carriers.
