Abstract
An efficient dedicated retransmission scheme for reliable multicast services is proposed to improve performance with respect to throughput and resource utilization in OFDMA systems. Through analysis and simulation, we show that the downlink cell throughput of the proposed scheme is much greater than that of the conventional scheme. In addition, the proposed scheme saves a much greater amount of downlink resources than the conventional scheme.
