Cloud RAN architecture model based upon flexible RAN functionalities split for 5G networks

Abstract : Cloud Radio Access Network (Cloud RAN) is novel mobile network architecture. It uses cloud computing capabilities to enhance the quality of service (QoS) in next generation 5G networks. The basic concept of Cloud RAN is to separate the digital baseband processing units (BBUs) of conventional cell sites, from the Remote Radio Heads (RRHs), and move them to the cloud for centralized signal processing and management. In this paper, we highlight key technologies and tradeoffs that drive Cloud RAN. We propose a new model of C-RAN architecture which introduces a flexible split of RAN functionalities between an edge cloud, Cloud-RRH, and the central Cloud. We conclude with a performances comparison between the proposed model and different C-RAN architectures.
