A Two-Way Relay Channel (TWRC) is studied over quasi-static fading channels by focusing on the throughput of Type-I HARQ strategies. An upper bound is evaluated, along with a number of achievable results obtained by proposing different protocols combining Type-I HARQ with standard amplify or decode-and-forward techniques or more sophisticated lattice code-based strategies. Performance comparison among the different protocols shows a trade-off between the achievable throughput and the system overhead required to obtain partial channel state information at the nodes.

Abstract

A Two-Way Relay Channel (TWRC) is studied over quasi-static fading channels by focusing on the throughput of Type-I HARQ strategies. An upper bound is evaluated, along with a number of achievable results obtained by proposing different protocols combining Type-I HARQ with standard amplify or decode-and-forward techniques or more sophisticated lattice code-based strategies. Performance comparison among the different protocols shows a trade-off between the achievable throughput and the system overhead required to obtain partial channel state information at the nodes.
