Claim:
1. A method for controlling a transmission power by a transmitter in a wireless communication system, the method comprising: transmitting a reference signal to a first receiver and a second receiver; receiving a first feedback signal transmitted based on first transmission power in the first receiver and a second feedback signal transmitted based on second transmission power in the first receiver, with respect to the reference signal; determining a sum of received signal strengths of the first feedback signal and the second feedback signal; determining a power control value based on channel state information included in each of the first feedback signal and the second feedback signal and the sum of the received signal strengths; and controlling the transmission power of the transmitter based on the determined power control value, wherein the first transmission power is determined based on a received signal strength and an interference and noise strength measured in the first receiver, and wherein the second transmission power is determined based on a received signal strength and an interference and noise strength measured in the second receiver.
