Abstract:
The present invention provides an enhanced H-ARQ scheme that optimizes bandwidth utilization and spectrum efficiency. When an H-ARQ attempt is unsuccessful due to loss or error over a hop between the BS and MS/SS, then only the first node in the hop chain that fails to decode the packet transmits another H-ARQ attempt. The BS determines the first node that fails on decoding based on certain information such as the feedback information sent from the nodes on the path. The previous node of the failed node is then instructed to retransmit by the BS.
