Cloud-Based Wi-Fi Network Using Immediate ACK in Uplink Data Transmissions

IEEE Access, 2018
In a cloud-based network architecture, the central unit (CU) at the cloud coordinates wireless nodes such as the remote access units (RAUs) at the edges of the network and manages most functions for providing wireless connectivity services to clients ...

Double Deep Q-Network-Based Energy-Efficient Resource Allocation in Cloud Radio Access Network

IEEE Access, 2021
Cloud radio access network (CRAN) has been shown as an effective means to boost network performance. Such gain stems from the intelligent management of remote radio heads (RRHs) in terms of on/off operation mode and power consumption.

An Architecture to offer Cloud-Based Radio Access Network as a Service [PDF]

, 2014
This paper addresses the novel notion of offering a radio access network as a service. Its components may be instantiated on general purpose platforms with pooled resources (both radio and hardware ones) dimensioned on-demand, elastically and following ...

On User Mobility in Dynamic Cloud Radio Access Networks [PDF]

IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018
The development of virtualization techniques en- ables an architectural shift in mobile networks, where resource allocation, or even signal processing, become software functions hosted in a data center. The centralization of computing resources and the dynamic mapping between baseband processing units (BBUs) and remote antennas (RRHs) provide an ...

Towards a Cloud-Native Radio Access Network

, 2016
Commoditization and virtualization of wireless networks are changing the economics of mobile networks to help network providers, e.g. Mobile Network Operator (MNO), Mobile Virtual Network Operator (MVNO), move from proprietary and bespoke hardware and ...

Capacity Bounds on the Downlink of Symmetric, Multi-Relay, Single-Receiver C-RAN Networks

Entropy, 2017
The downlink of symmetric Cloud Radio Access Networks (C-RANs) with multiple relays and a single receiver is studied. Lower and upper bounds are derived on the capacity.
