1. a radio communication device, including:

  • Propagation path quality acquiring unit, receives the measurement result of propagation path quality from communication counterpart device;

    MCS setup unit, sets modulation and the coded system including encoding rate according to the measurement result of described propagation path qualityMCS;

    Coding unit, transmits data according to described MCS coding;

    Retransmission controlling unit, based on the response signal transmitted from described communication counterpart device, controls the re-transmission of the data transmitted;

    Parameter bits number setup unit, sets the bit number of Retransmission control parameter, with when described according to the encoding rate transmitted firstWhen encoding rate is equal to or less than predetermined value, reduce the bit number of described Retransmission control parameter;

    Retransmission control parameter setting unit, sets described Retransmission control parameter by the bit number set by using;

    Control signal generation unit, produces the control letter with the control information including described MCS and described Retransmission control parameterNumber;

    AndTransmit processing unit, transmit described control signal and coded data to described communication counterpart device.
