A strategy for joint service offloading and scheduling in heterogeneous cloud radio access networks [PDF]
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 band unit, and keeping remote radio heads on cell site enabling a centralized processing and ...

Cloud radio access meets heterogeneous small cell networks: A cognitive hierarchy perspective [PDF]
2016 IEEE 17th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2016 In this paper, the problem of distributed power allocation is considered for the downlink of a cloud radio access network (CRAN) that is coexisting with a heterogeneous network. In this multi-tier system, the heterogeneous network base stations (BSs) as well as the CRAN remote radio heads seek to choose their optimal power to maximize their users ...

Green Heterogeneous Cloud Radio Access Networks: Potential Techniques, Performance Trade-offs, and Challenges [PDF]
IEEE Communications Magazine, 2017 As a flexible and scalable architecture, heterogeneous cloud radio access networks (H-CRANs) inject strong vigor into the green evolution of current wireless networks. But the brutal truth is that energy efficiency (EE) improves at the cost of other indexes such as spectral efficiency (SE), fairness, and delay.
