In wireless decode-and-forward (DF) relaying networks, the hybrid ARQ (HARQ) process suffers severe latency, especially when centralized scheduling is employed. We propose a new distributed HARQ based cooperative relaying (DHCR) protocol to reduce the latency. Based on the reception quality of the 1st hop, each relay station (RS) independently processes and forwards the data stream in such a manner...
Wireless decode-and-forward (DF) relay networks suffer from severe latency due to multi-hop propagation. When hybrid ARQ (HARQ) is employed, the latency leads to the throughout degradation of individual HARQ processes because of the decreased number of retransmissions of unsuccessful packets in a given time. We propose two new distributed cooperative HARQ protocols to not only reduce latency but also...
