Apparatus and method for channel quality information feedback in wireless communication system using fequency qudrature amplitude modulation

FQAM a method of operating a base station is provided in a wireless communication system that supports (Frequency-Quadrature Amplitude Modulation). The method includes the ratio of the channel quality information and the data region includes the steps of determining a modulation and coding level based on the Gaussian information-Gaussian (non-Gaussian) the method comprising the steps of: receiving from the terminal information and the channel quality information and the non- do.
