摘要：In this paper, we present two novel ARQ schemes for mobile multicast, which utilize packet-combining to reduce the number of retransmissions. The spectral efficiency of these multicast ARQ schemes are optimized jointly with adaptive modulation and coding (AMC) under specific QoS constraints, and numerical results show that significantly gains can be achieved comparing to schemes without packet-combining. Delay analysis has also been fulfilled for adopting the proposed sub-optimal scheme in practical systems. © 2011 IEEE.
