Abstract:
1. A method for generating uplink signals in a communication system, the method comprising: multiplying an information symbol by a sequence having a length corresponding to a number of sub-carriers contained in a resource block to generate first output symbols; multiplying the first output symbols by a spreading code having a certain length corresponding to a number of Single Carrier Frequency Division Multiple Access (SC-FDMA) or Orthogonal Frequency Division Multiple Access (OFDMA) symbols used for the uplink signals in a resource block to generate second output symbols, wherein the second output symbols include a plurality of symbol blocks, each of the plurality of symbol blocks being related to the first output symbols; mapping the second output symbols on resources of the resource block such that each of the plurality of symbol blocks is mapped on sub-carriers of a corresponding to a SC-FDMA or OFDMA symbol; and generating SC-FDMA or OFDMA signals from the resource block.
