A Fair Score-Based Scheduler for Spatial Transmission Mode Selection

Multi-antenna radio systems which are capable to select the spatial transmission mode according to the current channel conditions promise to achieve high transmission rates. Considering multiple users, the rates can be further increased if the multi-user diversity is properly utilized. However, fairness constraints have to be taken into account here to ensure that each user will be assigned any resources at all. We present a score-based scheduling solution which enables to adapt the degree of fairness supposed to be provided in the resource allocation process, and which further supports spatial transmission mode selection to attain a high overall throughput.
