The diversity-multiplexing tradeoff for multiple-input multiple-output (MIMO) point-to-point channels and multiple access channels were first proposed and studied by Zheng and Tse recently. While the optimal tradeoff curves for MIMO channels have been explicitly explored, those corresponding to some suboptimal and practical MIMO schemes are still open. One such important problem is the diversity-multiplexing...
Different from conventional multiuser scheduling schemes targeting on optimizing the physical layer performance criteria such as Shannon capacity and error probability, in this paper we propose a family of new scheduling methods that take the packet throughput in upper-layer protocols into considerations. This new performance metric appears to be an elegant combination of spectral efficiency and channel...
