Abstract:
In a radio communication system including a base station apparatus 10, a relay station apparatus 20 that receives a signal transmitted from base station apparatus 10 and re-transmits the signal to terminal apparatuses, a terminal apparatus 30 that directly receives the signal transmitted from the base station apparatus and a terminal apparatus 32 that receives the signal transmitted from base station apparatus 10 via relay station apparatus 20, base station apparatus 10 sets the transmission power of a signal addressed to terminal apparatus 30 high and the transmission power of a signal addressed to terminal apparatus 32 low, adds up the signals and transmits the resultant signal. With this, the signal addressed to the terminal apparatus that directly communicates with the base station apparatus and the signal addressed to the terminal apparatus that communicates with the base station apparatus via the relay station apparatus are multiplexed and transmitted simultaneously, whereby it is possible to provide a radio communication system and the like that enable efficient communication.
