摘要：

To maximize the spectral efficiency for a time-varying downlink channel with multiple users, the scheduling order of the users needs to be optimized. The scheduling problem naturally is a combinatorial optimization problem with high complexity, which exponentially increases with the number of users. This paper proposes several low-complexity scheduling algorithms. Computer simulation results show that the proposed algorithms approach optimal performance.
