In order to improve cell capacity in multihop networks, we propose a novel adaptive relay scheme based on hierarchical constellations in which a symbol consists of multiple bits with varying degrees of robustness against channel errors. These bits are transferred to multiple users, such as relays and destinations, adaptively according to the users' channel conditions and this adaptive transfer enables the capacity of multi-hop networks to be improved.
