УСТРОЙСТВО РАДИОСВЯЗИ И СПОСОБ РАДИОСВЯЗИ

摘要

There is provided a radio communication device capable of suppressing increase of power consumption of a relay station device. In this device, a channel information extraction unit (31) extracts channel information (channel information in the mobile station device of the signal transmitted from the base station device) from the reception signal from a base station device; a sub carrier selection unit (32) selects a sub carrier of low received quality according to the channel information; a relay data extraction unit (33) extracts data to be relay-transmitted according to the selection result in the sub carrier selection unit (32); and a sub carrier allocation unit (35) allocates data to be relay-transmitted to the sub carrier for relay transmission.
