A Proportional Fair Scheduling Based on OFDMA for Wireless Multicast Service

In order to improve the throughput in wireless multicast scenario, a new type inter-group proportional fairness scheme with average block error rate threshold is proposed, which can not only guarantee fair radio resource allocation but also provide better balance between multi-user diversity and the multicast gain. Theoretical analysis and simulation show that the proposed scheme can effectively improve the wireless multicast system throughput subject to constraint on the average error block rate in comparison with the existing approaches.
