1. A radio communication apparatus comprising:

  • a coding section that codes transmission data at a changeable coding rate;

    a modulation section that performs modulation using one of a plurality of modulation schemes; and

    a control section that tentatively determines an MCS level in accordance with channel quality, compares the tentatively determined MCS level with an MCS level used in previous control, determines the tentatively determined MCS level when a level difference is within the predetermined fluctuation range or determines an MCS level having a level difference with respect to the MCS level used in previous control limited within the fluctuation range when the level difference exceeds the fluctuation range, and controls the coding section and the modulation section so as to have the determined MCS level.
