摘　　要：为了解决在室内多用户多输入多输出(MU-MIMO)场景下,时分双工上行高速分组接入(TD-HSUPA)系统的多用户调度问题,提出了一种新的调度和用户配对算法.该算法综合考虑了接收天线间的流间干扰和同一接收天线内的码间干扰.通过将用户动态接入不同基站天线服务列表,所提算法能在保持用户公平性的前提下明显提升基站平均吞吐量.该算法运算复杂度低,无需增加信令开销,适用于实际室内系统中.A new scheduling and user pairing algorithm is proposed for the time division high speed uplink packet access（TD-HSUPA） system to address the indoor multi-user in multiple-input multiple-output（MU-MIMO） scenario.The impacts of multi-stream interferences between different receiving antennas and co-channel interference within the same antenna are considered.By admitting different users into different antennas＇ serving user lists,the proposed algorithm can significantly improve average system throughput while maintaining good user fairness.It is suitable to deploy the proposed scheme in practical indoor systems due to its low computational complexity and little additional signaling costs.
