Abstract
In a receiving side apparatusreception quality of receive data is measured by a reception quality measurement sectionreceive data errors are detected by an error detection sectionand when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation sectionIn a transmitting side apparatuswhen a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatusis detected from a reception quality signal by a scheduling sectionand 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.
