Cloud RAN Challenges and Solutions
Annales Des Telecommunications/Annals of Telecommunications, 2017In this paper, we take an overall look at key technical challenges in the evolution of the radio access network (RAN) architecture towards Cloud RAN and solutions to overcome them. To address fronthaul limitations, we examine the implications and tradeoffs enabled by functional splits on fronthaul needs, system performance, and centralization scale. We

Cloud RAN for Mobile Networks—A Technology Overview [PDF]
IEEE Communications Surveys and Tutorials, 2015 Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which can address a number of challenges the operators face while trying to support growing end-user's needs. The main idea behind C-RAN is to pool the Baseband Units (BBUs) from multiple base stations into centralized BBU Pool for statistical multiplexing gain, while shifting ...

Resilient Cloud-RANs Adopting Network Coding [PDF]
Lecture Notes in Computer Science, 2020 This study focuses on the provisioning of resilient Cloud Radio Access Network (C-RAN) services employing optical transport networks. In response to the high bandwidth requirements necessary for the protection of the C-RAN architecture from optical transport network and/or BBU failures, a novel approach based on Network Coding (NC) is proposed. A novel

Group Sparse Beamforming for Green Cloud-RAN [PDF]
IEEE Transactions on Wireless Communications, 2014 A cloud radio access network (Cloud-RAN) is a network architecture that holds the promise of meeting the explosive growth of mobile data traffic. In this architecture, all the baseband signal processing is shifted to a single baseband unit (BBU) pool, which enables efficient resource allocation and interference management.

On dimensioning Cloud-RAN systems
Proceedings of the 11th EAI International Conference on Performance Evaluation Methodologies and Tools, 2017We investigate in this paper the implementation of a Cloud-RAN architecture, where several software-based Base Band Units (BBUs) are collocated in a cloud data center. We specifically study several scheduling strategies in order to accelerate the runtime of virtualized BBU functions, and thus, to increase the span of a Cloud-RAN system, given that ...
