CPU-MPU partitioning for C-RAN applications

7th International Conference on Communications and Networking in China, 2012
This paper discusses methods for employing co-processors for off-loading the general purpose CPU in a cloud RAN application. A new concept, termed Modem Processing Unit (MPU) is introduced, in which the data path is offloaded from the CPU. The MPU concept provides benefits in overall throughput and power consumption, and alleviates the data transfer ...

G-NOMA for Energy Efficient C-RAN

2020 IEEE 18th International Conference on Industrial Informatics (INDIN), 2020
As 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.

Rate Splitting Multiple Access in C-RAN

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
Rate-splitting multiple access (RSMA), recognized as a promising technique for future communication systems to generalize and outperform existing multiple access techniques, has been shown to enhance the spectral and energy efficiencies of multi-user multi-antenna broadcast channels (BCs).

A Flexible Research Testbed for C-RAN

2015 Euromicro Conference on Digital System Design, 2015
This 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, 2016
Abstract—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, 2018
This 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), 2017
Conventional 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 ...
