In the multiple-input multiple-output(MIMO) system with limited feedback, traditional multiuser scheduling algorithm only takes account of the sum rate, and the requirement for quality of service(QOS) is always neglected, especially the strain rate. In this paper, we propose an improved scheme, with both the sum rate and the strain rate taken into consideration. Users which don’t meet strain rate temporarily stop communicating. Simulation results show that the sum rate decreases, the difference between traditional and improved algorithm is small in lower SNR and tends to be stable with increased SNR. At the same time, bit error rate performance of communicating users could be improved greatly because users which don’t meet the strain rate don’t disturb system any more. Therefore, the new scheme behaves favorably at both system sum rate and performance.
