摘要：
In this paper, we propose a Group-Oriented QoS-Enhanced proportional fair (GQPF) scheduling algorithm, which aims at maximizing QoS throughput while still retaining fairness as well as maximizing system throughput in downlink OFDMA networks. GQPF proposes a Group-Oriented QoS-enhanced PF-based utility function for multi-channel OFDMA networks. We demonstrate via extensive simulation results, that GQPF outperforms PF in terms of system throughput and mean delay. The results show that GQPF well accommodates nearly twice the amount of high priority data than PF does.
