On Mobility and Cross-Layer Scheduling

— In this paper we investigate the impact of mobility on downlink scheduling in multi-user multiple antenna systems. We formulate several different designs of the cross-layer scheduler and evaluate how their throughput and fairness performance change as user mobility varies. Our model captures both the physical layer and system-level parameters affected by mobility. The results have shown how sensitive the different scheduler designs are with regard to user mobility and provide new insights into how the scheduler should be designed according to mobility conditions.
