Abstract

In the downlink of a multi-user MIMO system, the base station can multiplex signals intended to different users on the same spectral resource. Joint optimization of channel assignment (scheduling) and beamforming in such a scenario is an open problem. Assuming zero-focing linear beamforming at the base station, this paper addresses this task by investigating a novel greedy solution that approximately maximizes the sumrate. Performance of the proposed method is studied through numerical simulation and compared with known solutions based on combinatorial search. © 2006 IEEE.
