Radio resource calendaring in cloud-based radio access networks

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 ...

Collaborative radio access of heterogeneous cloud radio access networks and edge computing networks

2016 IEEE International Conference on Communications Workshops (ICC), 2016
Although the technical merits of the heterogeneous cloud radio access networks (H-CRAN) architecture have been well demonstrated in terms of data rate enhancement and ubiquitous wireless service provisioning, solely relying on the H-CRAN may not be sufficient to further support full automation and everything-to-everything (X2X) connection for the next ...

Optical access network technologies for future radio access networks

2017 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2017
This paper describes optical access network technologies that support future radio access networks. Packet-based BBU is expected to accommodate multiple services and PON with low-latency scheme is a promising candidate to for MFH transmission in future radio access networks.

Migration of Existing Access Networks Towards Multi-Radio Access

IEEE Vehicular Technology Conference, 2006
Integration of heterogeneous access technologies to provide multi-radio access allows for dynamic access selection. The "always best connected" paradigm can increase system capacity and end user throughput, as well as, reduce the network deployment costs for multi-radio wireless networks.

Photonics for radio access networks

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
In this work we analyse radio access networks (RAN) deployments from the capacity and cost points of view. We find that in order to support the new radio (NR) with system bandwidth of 800MHz and reduce the number of fibre connections between NR and baseband units (BBU) one can use dense wavelength division multiplexing (DWDM), pulse amplitude ...

Blockchain Radio Access Network Beyond 5G

IEEE wireless communications, 2020
We present a blockchain radio access network (B-RAN) as an advanced wireless access paradigm. The proposed B-RAN unites massive trustless subnetworks to form a large-scale trustworthy cooperative network by leveraging the blockchain principle.
