Wireless Communication Method and Apparatus Therefor

A wireless communication apparatus for performing wireless communication with a corresponding wireless communication apparatus with adaptively selecting a modulation scheme from a plurality of modulation schemes, comprising

• a signal quality grasping unit grasping a quality of a received signal based thereon;
• a first selection unit selecting a first modulation scheme based on the quality of the received signal grasped by the signal quality grasping unit;
• a retransmission rate calculation unit calculating a retransmission rate of received signals in the first modulation scheme;
• a throughput estimating unit determining an estimated throughput from the retransmission rate calculated by the retransmission rate calculation unit based on relations between throughput and retransmission rate;
• a comparison unit comparing the estimated throughput estimated by the throughput estimating unit with a throughput in a second modulation scheme having a smaller multi-value number than that in the first modulation scheme;
• and
• a second selection unit selecting either the first modulation scheme or the second modulation scheme based on the comparison result.
