dc.description.abstractWe consider the problem of downlink scheduling for multi-user OFDM (Orthogonal Frequency Division Multiplexing) systems. We derive optimal scheduling policies under three QoS/fairness constraints -- temporal fairness, utilitarian fairness, and minimum-performance guarantees. To calculate these optimal policies, we interpret the problem as a maximal bipartite matching problem. To solve this problem, we apply the modified Hungarian algorithm and a practical suboptimal algorithm. The simulation results show that our schemes achieve significant improvement in system performance compared with a non-opportunistic scheme.
