Efficient transport of enhanced CPRI fronthaul over PON [Invited]

Journal of Optical Communications and Networking, 2023
Passive optical networks (PONs) facilitate small-cell deployments. Back- and midhaul over PON is being deployed today. As opposed to point-to-point optics, PON extends the aggregation gain into the access domain.

Rethink fronthaul for soft RAN

IEEE Communications Magazine, 2015
In this article we discuss the design of a new fronthaul interface for future 5G networks. The major shortcomings of current fronthaul solutions are first analyzed, and then a new fronthaul interface called next-generation fronthaul interface (NGFI) is proposed.

Energy-Efficient Cell-Free Massive MIMO with Wireless Fronthaul

Asilomar Conference on Signals, Systems and Computers
Cell-free massive MIMO improves the fairness among the user equipments (UEs) in the network by distributing many cooperating access points (APs) around the region while connecting them to a centralized cloud-computing unit that coordinates joint ...

Next Generation Mobile Fronthaul Architectures

Optical Fiber Communication Conference, 2015
The evolution to ever higher radio bandwidths and the massive introduction of new services and technologies in 5G networks, along with their challenging requirements in the time and frequency domain will warrant revisiting the present CPRI fronthaul approach.

Optical solutions for fronthaul application (invited)

2015 14th International Conference on Optical Communications and Networks (ICOCN), 2015
Fronthaul using CPRI between BBU and RRU equipments is carried by bare fiber currently. As BBUs are more and more centralized as a pool, tremendous amount of connections may exhaust the dark fiber resource. Various optical solutions are proposed to carry CPRI.

Diversity coded 5G fronthaul wireless networks

2017 Wireless Telecommunications Symposium (WTS), 2017
In this paper we study the application of Diversity Coding to enable near-instantaneous recovery from link failures in 5G wireless Cloud Radio Access Network (C-RAN) networks. We focus on networks where remote radio heads in a C-RAN are connected to the baseband unit in two hierarchical tiers with optical and wireless fronthaul links. In order to avoid

Jitter impact on mobile fronthaul links

Optical Fiber Communication Conference, 2014
An innovative setup for thorough jitter characterization in fronthaul links is introduced. Tests have been carried out on an operating LTE fronthaul link measuring jitter impact on BER, EVM and frequency deviation.

Processing Resource Allocation in 5G Fronthaul

2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC), 2019
A dynamic simulator is, for the first time, proposed to evaluate solutions generated by a meta-heuristic based on the greedy randomized adaptive search procedure (GRASP) and variable neighborhood descent (VND) to ensure reliability in the optical fronthaul with the functional split recommended to the fifth generation (5G) cellular network architecture.

Fronthauling for 5G and beyond

2017
This chapter focused on the practical aspects of fronthauling the next generation radio access networks. One of the important characteristics of 5G RAN is likely to be an increased degree of coordination between RAN nodes in networks that are becoming more dense.
