Automated service delivery platform for C-RANs

2017 Second International Conference on Fog and Mobile Edge Computing (FMEC), 2017
Cloud computing is gaining significant attention and virtualized data-centers are becoming popular as cost-effective infrastructure. Recently, there has been a trend to collocate the baseband unit (BBU) functionalities and services from multiple cellular base stations into centralized BBU pool for statistical multiplexing gain.

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 ...

Design methodologies and algorithms for survivable C-RAN

2018 International Conference on Optical Network Design and Modeling (ONDM), 2018
In centralized/cloud radio access networks (C-RANs), baseband units (BBUs) are decoupled from remote radio units (RRUs) and placed in BBU hotels. In this way baseband processing resources can be shared among RRUs, providing opportunities for radio coordination and cost/energy savings.

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).

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 ...

DoF of Sectored Cellular Networks with C-RAN

2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019
This paper investigates the per user Degrees of Freedom (DoF) for uplink in sectored cellular networks which employ C-RAN architecture. The network consists of $N$ base stations (BS) and $K\leq N$ base band unit (BBU) pools. The communication between BSs and BBU pools occurs by means of finite-capacity fronthaul links. In the network, the computing

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.

Enhanced C-RAN Using D2D Network

IEEE Communications Magazine, 2017
With the surge in smartphone sensing, wireless networking, and mobile social networking techniques, mobile crowdsensing (MCS) has become a promising paradigm for 5G networks. An MCS system's service quality heavily depends on the platform, which brings the users under a common cloud with very low delay.

Design of C-RAN fronthaul for LTE networks

2018 21st Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2018
C-RAN is a mobile network architecture that enables the share of network resources in a centralised data centre, being cost- effective to the operators. This work consists of a study on the impact of C-RAN in an operator's network, addressing models for the latency and the capacity needed per data centre. The costs associated with the implementation of
