Abstract:

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.
