    摘要: A disclosed radio communications apparatus adaptively controls a modulation method and coding rate (MCS) of a data channel in accordance with received channel quality information (CQI). This apparatus includes a first data table indicating a first corresponding relationship of the MCS with respect to the CQI; a second data table indicating a second corresponding relationship of transmission power of a control channel with respect to the CQI; a first selection portion that accesses the first data table so as to select the MCS of the data channel in accordance with the received CQI; a second selection portion that accesses the second data table so as to select the transmission power of the control channel in accordance with the received CQI; and a transmission portion that transmits the data channel in accordance with the selected MCS and the control channel at the selected transmission power.
