Abstract: An operation method of a first communication node in a communication system may comprise generating a codeword by performing coding on a data stream; generating modulation symbols by performing modulation on the codeword; performing DFT on N modulation symbols among the modulation symbols by using a plurality of DFT units; mapping output symbols of each of the plurality of DFT units to a resource; and performing IFFT on the output symbols mapped to the resource by using an IFFT unit.
