The current existed scheduling schemes which are generally derived from the antenna selection algorithms can improve the sum-rate of MU-MIMO system to some extent.However,these schemes can not make the best of multi-user diversity gain,thus incurring capacity loss.To overcome these disadvantages,in this paper,a novel user scheduling scheme based on the lower bound capacity of MU-MIMO broadcast channel is proposed for the multi-user zero-forcing precoding system.In the proposed scheme,the base station will schedule those users that can achieve the maximal lower bound capacity of MU-MIMO system by certain optimal criterion.Simulation results are exhibited to indicate that the proposed scheme can provide performance improvement than other existed scheduling schemes.
