摘要

Ultra-Dense Network (UDN) is considered to be the key enabler for realizing capacity goals set by 5G.The major concern in UDN deployment is the backhaul network,which should be scalable,cost-effective,and have sufficient capacity to support massive small cell traffic.Otherwise,the backhaul can become the bottleneck of the network.In this paper,we propose a wireless backhaul solution for UDN deployment by considering MultiPath-MultiHop (MPMH) backhaul architecture in mmWave frequency band.In addition,we propose a distributed routing scheme to forward the backhaul traffic over the multihop network.Backhaul capacity and line-of-sight probability of the proposed backhaul architecture for various picocell densities were compared with direct,multiple-association,and multihop backhaul schemes under interference limited scenarios in outdoor and indoor small cell deployments.The simulation results indicate that the MPMH mmWave backhaul is the most cost-effective and scalable solution for UDN deployment.
