Optimal HARQ procedures for reverse link

This paper presents optimal HARQ procedures for reverse link of next generation wireless communication systems. Different criteria are proposed for different classes of services, including the delay-intolerant ones. For delay-tolerant services the IR (incremental redundancy) gain is fully exploited and the gain brought by retransmissions are evident. For delay-intolerant services the ratio of their interference to their throughput is minimized while the IR gain is relatively small and less retransmissions are preferred to keep delay acceptable.
