摘要： PROBLEM TO BE SOLVED: To obtain a control method for retransmission appropriately allocating retransmission data to a subcarrier excellent in line quality at all times, and capable of suppressing degradation in throughput. SOLUTION: In the control method of retransmission, a mobile station measures quality in receiving line at every subcarrier or subcarrier group, and the measured quality is returned. Further, retransmission is required when an error is recognized in the received data. A base station required to be retransmitted transmits the retransmission data using the subcarrier other than the subcarrier or the subcarrier group determined as unused, on the basis of a predetermined information with respect to the line quality. The mobile station demodulates the retransmission data allocated to the subcarrier other than the subcarrier or the subcarrier group determined as unused. COPYRIGHT: (C)2008,JPO&INPIT
