Abstract

This paper addresses the scheduling problem for multiuser multi-input multi-output (MU-MIMO) system based on Tomlinson-Harashima Precoding (THP). By considering the channel gain and channel correlation jointly, a low-complexity multiuser scheduling approach is proposed. Compared with the existing scheduling schemes, the proposed scheme can avoid complicated searching process, and thus reduce the scheduling burden at the MAC layer significantly. Simulation results show the sum rate performance of the proposed scheme is nearly optimal although its complexity is very low.
