Abstract
Systems and methods for packet re-transmission in multi-hop wireless networks are provided. RLP packet retransmission only starts from the hop where L1 ARQ fails. This may result in an increased efficiency of radio resource utilization. In particular, the benefit may be greatest for implementations where the last hop is more unstable than the remaining hops. This is the case for the cellular downlink where the last hop is between a relay and a mobile terminal, and this hop is typically the most unstable. However, applications are not limited to this particular case. Any improvement in RLP recovery delay may be translated into an improvement in system capacity and per-terminal throughput.
