IEEE 802.16j Mobile Multi-hop Relay (MMR) was proposed to gain coverage extension and throughput enhancement. The objective of this paper, is to suggest a coded cooperative networking MAC protocol in non transparent multihop WiMax network. The proposed design takes in consideration network coding approach between relays. The authors try to address the division of an IEEE 802.16j frame into different zones. They suggest a frame structure that supports 3 hops non transparent TTR mode. Related work and the 802.16j capability are also deeply discussed.
