COMBINED HARD/SOFT RELAY FORWARDING FOR HYBRID-AUTOMATIC REPEAT REQUEST (ARQ) EXPLOITATION

摘要

Technologies are generally presented for a relay forwarding system combining a data efficiency of soft forwarding that increases generalized signal-to-noise ratio (GSNR) with the ability to use hybrid-automatic repeat requests (H-ARQs) substantially high throughput levels may be maintained by using repair instead of packet re-requests. A relay may receive an incoming signal and perform both a soft forward to a relay destination and a non-forwarded hard decode within the relay. The hard decode results may be analyzed for errors locally to detect suspected bit errors and H-ARQ ACK/NACK signals may be sent so that retransmission can be obtained before a rolling buffer in the relay reaches frame end.
