    • 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.
    • 提供了一种在支持频率正交幅度调制(FQAM)和多音频频率正交幅度调制(MT-FQAM)的无线通信系统中操作基站的方法。 该方法包括:当至少一个资源块被包括在数据中时,以及资源块是否是包括用于确定发送数据的调制方法的过程和用于根据选择MT-FQAM方法的调制方法调制数据的处理 当至少一个资源块被包括在数据中时以及当资源块被连续地映射到至少一个音调时,连续映射到至少一个音调或者选择FQAM方法,并且当多个资源块选择MT-FQAM方法时 被包括在数据中,并且当资源块被分散地映射到至少一个音调时。
