Multihop cellular networks toward LTE-advanced

This article presents the architecture of MCN toward 3G LTE-Advanced with TDD. On the assumption that L2 RN and L3 RN can provide their own RRM functions, several important RRM functions including routing, link adaptation, and scheduling in MAC layers at RNs can help the eNB to handle the radio resources efficiently. In general, the RN with higher implementation complexity has the ability to provide more flexible RRM with more overhead. Our dynamic system-level simulations show that the MCN outperform the networks without relaying in terms of SINR and throughput.
