PROJECT TITLE :
Fronthaul and backhaul requirements of flexibly centralized radio access networks
Cloud radio access networks promise considerable edges compared to decentralized network architectures, but they additionally put challenging necessities on the fronthaul and backhaul network. Flexible centralization will relax these requirements by adaptively assigning totally different components of the processing chain to either the centralized baseband processors or the bottom stations based mostly on the load scenario, user state of affairs, and availability of fronthaul links. In this text, we tend to give a comprehensive overview of different functional split options and analyze their specific needs. We compare these necessities to out there fronthaul technologies, and discuss the convergence of fronthaul and backhaul technologies. By evaluating the aggregated fronthaul traffic, we show the advantages of versatile centralization and provide tips on how to line up the fronthaul network to avoid over- or below-dimensioning.
