The throughput performance of Mobile Station(MS) in the cell edge is bottle neck for the whole throughput performance of cellular MIMO system. For solving this bottle neck, a base station cooperation (BSC) MIMO technology has been proposed. In addition, in BSC multiuser MIMO (MU-MIMO), the freedom of assigning the wireless channel to user becomes large and thus large user diversity gain can be obtained. As a result, the larger capacity wireless communication can be established. In BSC MIMO, however, when the user is selected as large channel capacity is achieved, the selection is significantly complicated process. Meanwhile, the antenna of BS is far from each other. Therefore, BSC MIMO technique can construct the diversity for shadowing. Since the average SNR strictly depends on the shadowing effect, the average SNR is good criterion for selecting the user. This paper propose the user selection method based on the average received SNR for reducing the computational complexity but achieving large capacity in BSC MU-MIMO down-link system.
