ABSTRACT:
A method and apparatus for controlling a power of a relay are provided. The apparatus includes: a signal receiver which receives signals which are transmitted to a plurality of receiving antennas directly from a source or via at least one relay; a channel information acquirement unit which acquires channel information between the source and the at least one relay, and acquires channel information between the at least one relay and the plurality of receiving antennas; a power control signal generation unit which generates a power control signal, based on the acquired channel information and a maximum SNR; and a relay power control unit which transmits the generated power control signal to the relay and thereby controls a transmit signal power with respect to the at least one relay.
