MULTIHOP CELLULAR NETWORKS TOWARD LTE-ADVANCED Its Architecture and Performance

The multihop cellular architecture with relaying is expected to be a cost-effective solution to reduce the transmission distance and increase the amount of users under more favorable channel conditions with better channel quality and higher throughput. In this article, we present the architecture and evaluate the performances of multihop cellular networks (MCNs) for thirdgeneration (3G) long-term evolution (LTE) toward its advanced networks. First, the network architecture is introduced with the specific features of 3G LTE. Then, the frame structure based on time-division duplex (TDD) for relaying is proposed, and the relay nodes (RNs) are Digital Object Identifier 10.1109/MVT.2009.933474 © PHOTO F/X2
