APPARATUS AND METHOD FOR SYMBOL MAPPING IN WIRELESS COMMUNICATION SYSTEM USING MULTI TONE FEQUENCY QUDRATURE AMPLITUDE MODULATION

摘要

Provided is a method for operating a base station in a wireless communications system which supports frequency-quadrature amplitude modulation (FQAM) and multi-tone frequency-quadrature amplitude modulation (MT-FQAM). The method comprises a process for determining the modulation method of transmitted data and a process for modulating the data according to a modulation method which selects the MT-FQAM method, when at least one resource block is included in the data and when the resource block is successively mapped on at least one tone or which selects the FQAM method when at least one resource block is included in the data and when the resource block is successively mapped on at least one tone, and which selects the MT-FQAM method when multiple resource blocks are included in the data and when the resource blocks are dispersively mapped on at least one tone.
