This paper proposes a novel scheme that combines coded cooperation and truncated ARQ/FEC protocol at the physical and data link layers. Although the coded cooperation method can achieve remarkable diversity gains through independent fading channels, its characters such as bit error rate (BER) and spectrum efficiency are influenced greatly by inter-users' channel qualities. Hence, we introduced the truncated ARQ/FEC protocol in the cross-layer scheme which can decrease the error rate while each user decodes the packets of the partners. The code cooperation in our scheme can achieve more diversity gains even in poor inter-users' channel qualities. Simulation results show that our scheme can enhance the error-free performance and offer a desirable delay tradeoff both in RCPC-coded and Turbo-coded cooperation.
