HARQ in LTE uplink: A simple and effective modification suitable for low mobility users

In this paper a bayesian approach to increase the throughput and reduce the latency of the Hybrid-ARQ processes in the Long Term Evolution uplink is proposed. The performance of the enhanced system is evaluated and compared to the standard one using a theoretical framework based on the Accumulated Mutual Information and the theory of Markov chains. The proposed modification is simple to implement in real systems and it is shown to be effective, especially in low mobility scenarios.
