Abstract: A method for transmitting/receiving feedback information in a multi-antenna system supporting multiple users and a feedback system supporting the same are provided to improve performance of a closed-loop multi-antenna system by effectively allocating resources according to minimum feedback information. Receiving devices(120-1-120-N) determine a feedback protocol scenario defined according to a communication environment desired to be used among multiple feedback protocol scenarios, obtain feedback information requested by the desired communication environment, and transmit the obtained feedback information according to the determined feedback protocol scenario. A transmission device(110) determines a feedback protocol scenario defined according to the communication environment desired to be used among the multiple feedback protocol scenarios, and receives feedback information according to the determined feedback protocol scenario.

Abstract: A method for selecting an active user in zero forcing beamforming algorithm is provided to select a terminal, which has the largest channel capacity, as a transmission object terminal by receiving channel capacity information of remaining terminals except transmission object terminals previously selected until the number of terminals currently selected(i) becomes equal to a predetermined number(N) if (i) is different from (N), thereby reducing process complexity without degradation and ensuring service quality for a user by being embodied with proportional fair scheduling algorithm. A method for selecting a transmission object terminal comprises the following steps of: receiving channel capacity information of each terminal from total terminals(K)(S202); selecting a terminal, which has the largest channel capacity, as an initial transmission object terminal(S203); determining whether the number of terminals currently selected(i) is the same as a predetermined number(N)(S204); and receiving channel capacity information of remaining terminals except transmission object terminals previously selected until (i) becomes equal to (N) if (i) is different from (N) and selecting a terminal, which has the largest channel capacity, as a transmission object terminal(S207).
