Reconfigurable and efficient fronthaul of 5G systems
2015 IEEE International Conference on Advanced Networks and Telecommuncations Systems (ANTS), 2015Common Public Radio Interface (CPRI) is a popular standard to interface the Radio Equipment Control (REC) and the Radio Equipment (RE) in the fronthaul of 5G systems. However, CPRI is expensive to deploy, consumes high bandwidth and, currently, is statically configured. Reconfigurability is highly desirable in 5G systems, and can be classified into two

Optical Access Network Solutions for 5G Fronthaul
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018This paper first highlights the capacity and latency requirements of the 5G mobile fronthaul and the fronthaul architecture detailing also the motivations for these requirements. The it overviews the optical access network solutions that could be used for the fronthaul and for which functional split they are deemed more appropriate.

Diversity coded 5G fronthaul wireless networks
2017 Wireless Telecommunications Symposium (WTS), 2017In 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

5G Fronthaul Enabled by WDM Radio-over-Fiber
Frontiers in Optics / Laser Science, 2020We propose a low-cost DML-based hybrid fiber-wireless WDM radio-over-fiber transmission system for 5G fronthaul networks with resource allocation flexibility under different traffic loads and demonstrate it with a proof-of-concept experiment.

An Insight into the Total Cost of Ownership of 5G Fronthauling
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018This paper provides an assessment of the total cost of ownership (TCO) of a number of 5G fronthauling solutions based on digital and analog radio-over-fiber (RoF) architectures in cloud radio access network (C-RAN). We computed the capital and operational expenditures (CAPEX, OPEX) in the case of an optical fiber aggregation network based on a ring ...

MmWave Fronthaul-to-Backhaul Interference in 5G NR Networks
2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021Fixed point-to-point microwave links (P-P links) are widely used for vital backhaul connections in cellular networks. One frequency range allocated to P-P links by the International Telecommunications Union ranges from 24.25GHz to 29.5GHz. The same frequency range was also allocated to mobile services, with bands dedicated to 5G new radio (NR ...

Fronthaul in 5G Transport Networks: IEEE1914.1 Architecture and Requirements
2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020The deployment of 5G New Radio (NR) implies the capability both to deliver new mobile services (eMBB, URLLC, mMTC) and to perform critical functions as massive MIMO, beamforming, carrier aggregation, CoMP and scalable centralized/virtualized radio access network (C-RAN/V-RAN).
