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 ...

Resource Cost Balancing with Caching in C-RAN
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017Cloud radio access networks (C-RAN) are expected to be the backbone of next generation communication networks. In order to reduce the backhaul cost, which is a bottleneck in C-RAN, popular files are cached in local memories at remote radio heads (RRH's) and thus in close proximity to the users demanding it.

DoF of Sectored Cellular Networks with C-RAN
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019This 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

Design of C-RAN fronthaul for LTE networks
2018 21st Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2018C-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

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 ...

A Computation Workload Characteristic Study of C-RAN
2018 IEEE 38th International Conference on Distributed Computing Systems (ICDCS), 2018Driven by the surging demand of mobile applications and IoT devices, the amount of global mobile data traffic is estimated to increase sevenfold in the next few years and reach 69 exabytes per month by 2022. This rapid growing rate force telecom operator to adapt new wireless network technologies in order to deliver desired network performance and ...

DEMO: SDN-based network slicing in C-RAN
2018 15th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2018Network slicing is considered a key technology for the upcoming 5G system, enabling operators to efficiently support multiple services with heterogeneous requirements, over a common shared infrastructure. In this demo, we present a prototype for managing network slices in the Cloud Radio Access Network (C-RAN), which is considered the reference network

Dynamic Virtual Network connectivity for C-RAN backhauling
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017Aiming at satisfying in a cost-effective manner the forecast traffic growth that future mobile networks will need to support, traditional distributed Radio Access Networks (RANs) are evolving towards centralized architectures. Specifically, the Cloud-RAN (C-RAN) architecture has shown that can alleviate to some extent the ever increasing Total Cost of ...
