Ethernet-based fronthauling for cloud-radio access networks [PDF]

2017 19th International Conference on Transparent Optical Networks (ICTON), 2017
Standardization bodies such as IEEE and 3GPP, as well as other interest groups, are in the process of defining and standardizing different functional subdivisions within mobile network base stations, primarily to reduce the data rate requirements imposed on the transport architecture by 4th and 5th generation mobile systems.

Joint Optical and Wireless Resource Allocation for Cooperative Transmission in C-RAN

Sensors, 2020
Cooperative multipoint transmission (CoMP) is one of the most promising paradigms for mitigating interference in cloud radio access networks (C-RAN). It allows multiple remote radio units (RRUs) to transmit the same data flow to a user to further improve

Fronthaul for Cloud‐RAN Enabling Network Slicing in 5G Mobile Networks

Wireless Communications and Mobile Computing, 2018
This work considers how network slicing can use the network architecture Cloud‐Radio Access Network (C‐RAN) as an enabler for the required prerequisite network virtualization. Specifically this work looks at a segment of the C‐RAN architecture called the fronthaul network.

All-Optical Network Capacity for 5G Cellular Fronthaul

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In this paper, we have investigated the use of fast wavelength switching optical transmitters and a wavelength selective space switching all-optical network for cellular fronthaul applications. System capacity is calculated by using hard-deadlines that arise from the radio requirements and the physical constraints of the optical network.

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...
