摘要： A receiver receives information necessary for receive processing of a data channel via a corresponding control channel and executes the receive processing of the data channel based on the information received via the control channel. In the receiver, whether the control channel of a receive frame F1 has an error is monitored. And if there is an error, the data channel before demodulation of this receive frame is stored, and if the control channel of a retransmission frame F2, which is received subsequently, is normal, the stored data channel and the data channel of the retransmission frame are demodulated using the normal control channel information (parameters) of this retransmission frame, the demodulation results are synthesized, and decoding processing is performed based on the synthesized data.

摘要： A radio communication system includes a transmission apparatus configured to transmit data using a radio frame formed in one time block, to which a plurality of continuous or discontinuous frequency areas are assigned, and a reception apparatus configured to receive the data transmitted from the transmission apparatus by using the radio frame. The transmission apparatus transmits to the reception apparatus a radio frame provided in the beginning of the radio frame with a pilot which is a known signal used for measurement of reception quality and a control signal used for the control of demodulation at the reception apparatus. The reception apparatus transmits reception quality information concerning reception quality measured by the pilot, and the transmission apparatus performs a transmission process by using a radio frame format which does not include control information for the reception apparatus which has transmitted the reception quality information.
