Recently, multiple-input multiple-output (MIMO) systems have shown the potential to achieve high speed data transmission by improving spectral efficiency over wireless fading channels. In multiuser MIMO environment, the radio base station (Node-B) supports mobile user equipment (UE) with different quality-of-service (QoS) requirements, where the adopted scheduling scheme controls the selection of UEs for service provision and has an impact on the system performance. In this paper, we first analysis two basic scheduling rules which are combined with and without successive interference cancelation (SIC) receivers, respectively. Then, we propose the hybrid scheduler which outperforms the two rules in terms of system capacity. Simulation results show that the performances of conventional scheduling schemes greatly depends on the number of UEs, and hence the proposed scheme is robust to the number, achieving the improved capacity gain.
