Abstract
Disclosed herewith is a radio communication apparatus capable of selecting proper one of plural communication modes such as a MIMO communication system so as to obtain a higher communication rate within a range in which chain retransmission occurrence is prevented. The MIMO system deciding section of the transmitter unit decides a proper MIMO system with reference to the CQI value demultiplexed by a demultiplexer and the AMC table controlling section changes the MCS value step by step according to the transmission count and the result (success/failure) of the communication. Furthermore, the AMC table controlling section updates the mean rate in the measured rate table when the subject data is received successfully or when the transmission count reaches the maximum value.
