ABSTRACT:
In a receiving side apparatus150,reception quality of receive data is measured by a reception quality measurement section157,receive data errors are detected by an error detection section156,and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section158.In a transmitting side apparatus100,when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus150is detected from a reception quality signal by a scheduling section110,and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.
