Abstract :
In this paper, we propose a novel superposition coding aided multiplexed Hybrid Automatic Repeat Request (HARQ) scheme for the sake of improving the link-layer transmission efficiency. The detailed system design is presented and the achievable link-layer packet error rate as well as the link-layer transmission efficiency metric is quantified. It is demonstrated that our scheme substantially improves the attainable transmission efficiency and it is particularly suitable for delay-sensitive services.
