Abstract: A method and an apparatus for CQI(Channel Quality Indicator) control for adaptive modulation and coding in an OFDMA system improve capacity and fairness of the OFDMA system by variably controlling a size of a sub carrier group. A valid cluster is selected among clusters including one bin or more which are a plurality of subcarrier groups according to a predetermined standard(S335). An average CINR(Carrier-to-Interference-plus-Noise Ratio) of the valid cluster is calculated(S337). The optimum MCS level of each valid cluster is determined based on the average CINR value(S353). The optimum cluster among the valid clusters is determined based on the optimum MCS level(S373).
