A Bandwidth Adaptation Scheme for Cloud Radio Access Networks

2016
With the advent of Cloud Radio Access Networks (C-RAN) where base band units (BBU) have the ability to dynamically support the bandwidth allocation and centrally manage the bearers transmitted from the remote radio heads (RRH), bandwidth adaptation (BA) mechanism emerges as a promising solution to provide the required resources for C-RAN to provide ...

Multi-resource allocation in cloud radio access networks

2017 IEEE International Conference on Communications (ICC), 2017
Computational resource allocation is a critical issue for the baseband unit (BBU) pool in a cloud radio access network (C-RAN). There are multiple resources in a BBU, including CPU, memory, disk, etc. The virtual machines (VMs) have diverse requirements along these resources to handle the baseband signal processing of corresponding remote radio units ...

Cloud radio access network (C-RAN): a primer

IEEE Network, 2015
In the era of mobile Internet, mobile operators are facing pressure on ever-increasing capital expenditures and operating expenses with much less growth of income. Cloud Radio Access Network (C-RAN) is expected to be a candidate of next generation access network techniques that can solve operators' puzzle.

Collaborative hierarchical caching in cloud radio access networks

2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017
To deal with the severe challenge from explosively increasing mobile users' multimedia service requests in mobile networks, introducing cloud-based computing platform and content caching into radio access networks (RANs) has become an effective emerging technique. In this paper, we propose a collaborative hierarchical caching framework in cloud RANs (C-

Robust distributed compression for cloud radio access networks

2012 IEEE Information Theory Workshop, 2012
This work studies distributed compression for the uplink of a cloud radio access network, where multiple multi-antenna base stations (BSs) communicate with a central unit, also referred to as cloud decoder, via capacity-constrained back-haul links. Distributed source coding strategies are potentially beneficial since the signals received at different ...

Performance Analysis and Evaluation of Cloud Radio Access Networks

2018 International Conference on Computing, Networking and Communications (ICNC), 2018
The cloud radio access network (C-RAN) has been recognized as a promising paradigm for the emerging fifthgeneration wireless communication network. Unlike traditional coordinated multi-point (CoMP) technique aiming at cell edge users in long term evolution advanced (LTE-A) networks, CRANs support large-scale coordination (LSC) for the whole users owing
