Novel Resource and Energy Management for 5G integrated backhaul/fronthaul (5G-Crosshaul) [PDF]

2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017
The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework ...

Fronthaul cell outage compensation for 5G networks

IEEE Communications Magazine, 2016
5G networks are expected to bring the gigabits per second throughput level per user to reality by 2020. This is done using a combination of new and well known technologies such as C-RAN, self-organizing networks, ultra dense networks, massive MIMO, and millimeter waves. In new RAN architectures, C-RAN has been viewed as a promising 5G architecture that
