The flexibility of the media access control(MAC) layer has always been an important concern in the existing communication architecture. To meet the more stringent requirements under large-scale connections, the MAC layer structure needs to be optimized carefully. This paper proposes a new architecture of the MAC layer to optimize the complex communication backhaul link structure, which will increase the flexibility of the system and decrease the transmission delay. Moreover, an adaptive transmission time interval(TTI) bundling with self-healing scheme is proposed to further decrease the transmission delay and improve the quality of service(QoS). The simulation results show that the average transmission delay is greatly reduced with our proposed scheme. The bit error rate(BER) and the block error rate are also improved even if the channel changes drastically. 展开更多
