<P>PROBLEM TO BE SOLVED: To provide excellent communication by a radio communication system which performs retransmission by improving a degree of improvement of an error by retransmission by forming different frequency spectra during the retransmission by using different phase series. <P>SOLUTION: A communication controller is equipped with a retransmission radio resource control unit (4) which generates retransmission radio resource control information including a modulation system, an encoding rate, a chip pattern, a frequency of repetition, and a phase series and used for data retransmission based upon retransmission request information requesting data to be retransmitted and retransmission request data including a modulation system etc., of data where an error occurs, a transmission control unit (7) which inputs the retransmission radio resource control information and outputs control information regarding a radio parameter, and radio transmission units (8, 9, 10, 11, 12, and 13) which transmit retransmission radio resource control information and retransmission data to communication opposite sides based upon the control information output from the transmission control unit. <P>COPYRIGHT: (C)2007,JPO&INPIT |
