Event-oriented fronthaul resizing in 6G networks

2023
Network slicing techniques have been pointed out as key enablers of 6G networks due to their capability to run logical networks with diverse and conflicting requirements over the same infrastructure. Artificial intelligence has been often used to improve the resource management of slices, such as slice resizing.

RoF-Based Mobile Fronthaul Networks Implemented by Using DML and EML for 5G Wireless Communication Systems

Journal of Lightwave Technology, 2018
We investigate the feasibility of implementing a mobile fronthaul network (MFN) based on the radio-over-fiber (RoF) technology for the fifth generation wireless communication systems cost effectively by using either directly modulated lasers (DMLs) or ...

Green Federated Learning Over Cloud-RAN With Limited Fronthaul Capacity and Quantized Neural Networks

IEEE Transactions on Wireless Communications, 2023
In this paper, we propose an energy-efficient federated learning (FL) framework for the energy-constrained devices over cloud radio access network (Cloud-RAN), where each device adopts quantized neural networks (QNNs) to train a local FL model and ...

Radio over Fiber Based Fronthaul for Next-Generation 5G Networks

2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020
In this paper, we present the benefits, limitations, architectures, and milestones of the radio-over-fiber (RoF) network for application in the fronthaul of next-generation 5G mobile networks. RoF is conceived as the fronthaul of the fiber-wireless system based on a centralized radio access network (CRAN), where a fully centralized approach shifts the ...

Network Slicing Support by Fronthaul Interface in Disaggregated Radio Access Networks: A Survey

IEEE Transactions on Network and Service Management
Beyond 5G (B5G) and 6G networks must offer network slicing as a service to support disruptive applications using mobile network infrastructures. Moreover, network slicing as a service should enable the orchestration and management of disaggregated radio ...

Design of C-RAN fronthaul for LTE networks

2018 21st Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), 2018
C-RAN is a mobile network architecture that enables the share of network resources in a centralised data centre, being cost- effective to the operators. This work consists of a study on the impact of C-RAN in an operator's network, addressing models for the latency and the capacity needed per data centre. The costs associated with the implementation of

Reliable and resilient coordinated multi point fronthaul networks

2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON), 2018
Very fast link failure recovery and high throughput can be achieved via the synergistic combination of Diversity and Network Coding (DC-NC), an open-loop coding technique, in a wide variety of network architectures. In this paper, DC-NC is applied to enable recovering from a wireless link/node failure in the fronthaul portion of downlink Coordinated ...

Fiber-Wireless Fronthaul/Backhaul Network Architectures for 5G

2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018
5G-PHOS R &D project aims at architecting and evaluating 5G broadband networks for dense, ultra-dense and hotspot area use cases by capitalizing on existing wireless and optical technologies, while migrating from CPRI -based towards integrated Fiber-Wireless (FiWi) fronthaul/backhaul supporting mmWave mMIMO communications.
