  Abstract

In this paper, a user selection scheme is proposed for uplink MU-MIMO systems with HARQ. In each packet transmission time interval, the proposed scheme selects the users with the initially transmitted packet and those with the retransmitted packet together. Therefore, when the base station employs the reception procedure such as interference cancellation in which the detection results of transmitted packets can be correlated, the error performance of the initially transmitted packets can be improved by the presence of the retransmitted packets having a high reliability. This enables the MU-MIMO system with the proposed scheme to have increased throughput and decreased latency. Simulation results confirm that the proposed scheme can significantly improve the throughput and average latency of uplink MU-MIMO systems with HARQ.
