In this paper, we present a scheduling algorithm to exploit multi-user diversity with one bit feedback information for multi-user MIMO system. Instead, the users in a cell only need feed back one-bit information about the comparison between the channel quality indicator and the defined threshold Cth, and then BS allocates the channel resource to one user experiencing favorable channel conditions. Specially, we solve this problem achieving the optimum threshold for multiple antennas systems in presence of transmit correlation. Simulation results show that the proposed scheme achieves better performance in terms of the average system spectral efficiency than round robin scheduling scheme.
