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

摘要

A method of operating a base station in a wireless communication system supporting Frequency-Quadrature Amplitude Modulation (FQAM) and Multi-Tone FQAM (MT-FQAM) is provided. The method is a process of determining a modulation method of data to be transmitted, wherein the MT-FQAM method is when the resource blocks included in the data are at least one and the at least one resource block is distributedly mapped to at least one tone. If or if the resource block included in the data is one, and the one resource block is continuously mapped to at least one tone, select the FQAM scheme or the resource block included in the data is multiple and the multiple And selecting the MT-FQAM scheme and modulating the data according to the determined modulation scheme when the resource blocks of R are continuously mapped to at least one tone.
