Location-aware network operation for cloud radio access network

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
One of the major challenges in effectively operating a cloud radio access network (C-RAN) is the excessive overhead signaling and computation load that scale rapidly with the size of the network. In this paper, the exploitation of location information of the mobile devices is proposed to address this challenge. We consider an approach in which location-

Cloud Radio Access Networks

2013
Radio virtualization and cloud signal processing are new approaches to building cellular Radio Access Networks (RAN) that are starting to be deployed within the cellular industry. For cellular operators, Cloud RAN architectures that centrally define or decode transmissions, placing most of the base-station software stack within a data-centre, promise ...

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

Performance Analysis of Multicasting in Cloud-Radio Access Networks

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016
Cloud-radio access networks (C-RANs) are considered as energy efficient network architectures. Nevertheless, a dilemma in C-RAN architecture is to simultaneously optimize both spectral efficiency (SE) and energy efficiency (EE). In this paper, the tradeoff between SE and EE are studied considering a downlink multicasting transmission scenario in a C ...

A bandwidth adaptation mechanism for Cloud Radio Access Networks

Pervasive and Mobile Computing, 2017
The Cloud Radio Access Network (C-RAN) is regarded as the possible implementation approach of the next-generation mobile networks. C-RAN splits a traditional base station into remote radio heads (RRHs) and the base band unit (BBU). Many BBUs are co-located into a centralized BBU pool.

Power Model for Heterogeneous Cloud Radio Access Networks

2015 IEEE International Conference on Data Science and Data Intensive Systems, 2015
The cellular network performance is measured by its spectral and energy efficiency. Since the power consumption is an important key success for the upcoming heterogeneous (HetNet) communication system generations, component, linear, and parameterized power models are presented in this paper.

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 ...
