Hailing cloud empowered radio access networks
IEEE Wireless Communications, 2015Radio access networks empowered by CRAN is a new design paradigm that is drawing the attention of many researchers today to tackle the growing complexity of provisioning broadband wireless services. Because of the need to provide high data rates and better coverage simultaneously, operators are maintaining heterogeneous networks with cells of various ...

Radio resource calendaring in cloud-based radio access networks [PDF]
2018 Wireless Days (WD), 2018 Bandwidth calendaring refers to the possibility of shifting some bulk data transfers, typically of large size with less stringent real-time constraint, to the moments when the network is less congested. In this paper, we exploit calendering in radio resource allocation in Cloud-based Radio Access Networks (C-RANs), where calendaring naturally fits the ...

On efficient radio resource calendaring in cloud radio access network [PDF]
Computer Networks, 2019 Abstract We propose in this paper a radio resource allocation scheme in the context of Cloud-based Radio Access Networks (C-RAN) run by a single operator. We specifically leverage bandwidth calendaring, a technique that allows shifting bulk data transfers, typically of large size with less stringent real-time constraints, to future epochs when the ...

Resource sharing in heterogeneous cloud radio access networks
IEEE Wireless Communications, 2015Heterogeneous cloud radio access networks incorporate the heterogeneous network and cloud radio access network concepts for next generation cellular networks. H-CRANs exploit the heterogeneity of macro and small cells from HetNets, enabling cellular networks to achieve higher spectral efficiency. Meanwhile, concepts from C-RANs involving baseband units

On the capacity of cloud radio access networks
2017 IEEE International Symposium on Information Theory (ISIT), 2017Uplink and downlink cloud radio access networks are modeled as two-hop K-user L-relay networks, whereby small base-stations act as relays and are connected to a central processor via orthogonal links of finite capacity. Simplified versions of noisy network coding and distributed decode-forward are used to establish inner bounds on the capacity region ...

Pico Satellites for Cloud Radio Access Network
2019 IEEE 2nd 5G World Forum (5GWF), 2019Among main targets of fifth generation and beyond networks, there are perceived availability of 99.999% and ‘any-time anywhere’ connectivity. That would allow future generation networks to fully support very sensitive governmental services such as military and emergency ones.
