  • To exploit multi-user diversity for multi-user MIMO system, a scheduling algorithm is proposed based on one-bit feedback information in this paper. It is proved in this paper that the value of threshold is important for the system performance, and the problem how to select the optimum threshold for multi-user MIMO systems is solved through theoretical analysis. Simulation results show that the proposed scheme achieves good performance in terms of the average system spectral efficiency by exploiting the multiuser diversity.
