摘要

A system can suppress the degradation of the system's own throughput, while suppressing the interference with a different communication system sharing a frequency band with the system. In ST302, a base station selects a terminal (B) as a relay station. In ST305, the base station performs a separation between the subcarrier signals outside an FSS-used band and the subcarrier signals within the FSS-used band, and remaps the separated subcarrier signals within the FSS-used band to the subcarriers outside the FSS-used band. In ST306, the separated subcarrier signals outside the FSS-used band and the remapped subcarrier signals outside the FSS-used band are differentially transmitted at the same time. In ST308, the terminal (B) remaps signals received from the base station to the subcarriers within the FSS-used band and, in ST309, transfers those signals as remapped to a terminal (A). In ST310, the terminal (A) combines the signals transferred by the terminal (B) with signals received from the base station for decoding.
