Pilot Contamination Mitigation in Massive MIMO Cloud Radio Access Networks

IEEE Access, 2022
Massive multiple-input multiple-output (MIMO) technology is expected to achieve significant gains in both signal-to-noise-plus-interference ratio (SINR) and throughput for 5G cellular wireless networks.

A strategy for joint service offloading and scheduling in heterogeneous cloud radio access networks

EURASIP Journal on Wireless Communications and Networking, 2017
Cloud radio access network is one of the most promising cellular networks for the next generation of mobile networks. The basic idea of cloud RAN (radio access network) is virtualizing and centralizing the intelligent part of the base station, the base ...

On Cloud Radio Access Networks With Cascade Oblivious Relaying [PDF]

2021 IEEE Information Theory Workshop (ITW), 2021
We consider a discrete memoryless cloud radio access network in which K users communicate with a remote destination through 2 relays in a cascade. The relays are oblivious in the sense that they operate without knowledge of the users’ codebooks. We focus on a scenario where the first and second relays are connected through a finite-capacity error-free ...

Fiber link design considerations for cloud-Radio Access Networks [PDF]

, 2014
Analog radio over fiber (RoF) links may offer advantages for cloud-Radio Access Networks in terms of component cost, but the behavior of the distortion with large numbers of subcarriers needs to be understood. In this paper, this is presented in terms of

Green Cloud Radio Access Networks

CoRR, 2016
Cloud radio access networks (C-RAN) are a promising technology to enable the ambitious vision of the fifth generation (5G) communication networks. In spite of the potential benefits of C-RAN, the operational costs are still a challenging issue, mainly due to the centralized processing scheme and the large number of operating remote radio head (RRH ...

Coordinated scheduling for the downlink of cloud radio-access networks [PDF]

2015 IEEE International Conference on Communications (ICC), 2015
This paper addresses the coordinated scheduling problem in cloud-enabled networks. Consider the downlink of a cloud-radio access network (C-RAN), where the cloud is only responsible for the scheduling policy and the synchronization of the transmit frames across the connected base-stations (BS). The transmitted frame of every BS consists of several time/
