G-NOMA for Energy Efficient C-RAN
2020 IEEE 18th International Conference on Industrial Informatics (INDIN), 2020As a green wireless network access framework, cloud radio access network (C-RAN) has the advantages of reducing energy consumption and improving spectral efficiency. In this paper, we propose to maximize the energy efficiency (EE) in the downlink of the C-RAN.

A Flexible Research Testbed for C-RAN
2015 Euromicro Conference on Digital System Design, 2015This paper presents a laboratorial platform for the development and trial of C-RAN compliant features. As part of future mobile networks standardization, C-RAN is considered as an evolution of the current RAN, which inherent challenges represent an interesting topic of research among academic institutions and industry.

Soft-Stacked PON for Soft C-RAN
Journal of Optical Communications and Networking, 2016Abstract—Cloud radio access networks (C-RANs) feature central pooling baseband processing units (BBUs) and lowcost remote radio headends (RRHs) with fiber-connected fronthauls between them, and they are promising for 4G. Researchers are redesigning the C-RAN with different split approaches to relax the fronthaul capacity for 5G with massive antennas ...

Cooperation Strategies for Partly Wireless C-RAN
IEEE Communications Letters, 2018This letter presents a variant of cloud radio access network (C-RAN) architecture, which we term partly wireless C-RAN (PW-CRAN). It is characterized by extra radio nodes connected through the existing remote radio heads. Because of the newly connected nodes and the consequent additional delay, the operation of PW-CRAN requires different approaches ...

Flexible C-RAN: Radio technology for 5G
2017 13th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS), 2017Conventional radio access networks are designed to utilize static configuration and are statically deployed. As results they are inefficient in handling any spatio-temporal fluctuations of the underlying traffic demand. Cloud-RAN represents a novel centralized technology based on softwareization and virtualization technology that can efficiently ...

5G RAN Architecture: C-RAN with NGFI
2016This chapter discusses Cloud Radio Access Networks (C-RAN), which has been viewed as one of the key RAN architectures for 5G networks. First, the basic concept and the initially defined architecture of C-RAN are recalled, including the major benefits in terms of acceleration of network deployment, cost reduction and facilitation of 5G technologies ...

Cluster Based Dynamic Bandwidth Allocation C-RAN
International Journal of Electrical Engineering and Computer ScienceA wireless network is a collection of independent nodes or devices that communicate over a single network through a wireless link. Bandwidth allocation is a critical issue in wireless networks because network performance and costs are heavily dependent on this parameter.
