This paper first overviews possible evolved NodeB (eNB) functional splits. Then it illustrates which requirements the Radio Access Network (RAN) shall satisfy to effectively transport 5G protocol data units (PDUs) as a function of the considered functional split.

Rethink fronthaul for soft RAN
IEEE Communications Magazine, 2015In 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.

Joint Design of Fronthaul and Access Links for C-RAN With Wireless Fronthauling
IEEE Signal Processing Letters, 2016This letter studies a joint design of fronthaul and radio access links for a cloud radio access network (C-RAN) with wireless fronthauling, where a baseband unit (BBU) controls a number of remote radio heads (RRHs) via wireless fronthaul links to communicate with user equipments.

Scenarios and Economic Analysis of Fronthaul
Optical Fiber Communication Conference, 2018This work presents a comparison between C-RAN and emerging DA-RAN approaches for 5G networks. Main results show that DA-RAN and splitting alternative to CPRI bring economical and architectural advantages.

Coaxial Networks for 5G Fronthaul
2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018In this paper, we present an investigation about the potential of coaxial networks for 5G fronthaul. The study is motivated since some countries have a big coaxial infrastructure that could potentially be used for 5G applications. In this context, we propose here a fronthaul scheme with analog radio over coaxial cables and evaluate the maximum number ...

PWM fronthauling in reflective PON
2016 European Conference on Networks and Communications (EuCNC), 2016Pulse width modulation (PWM) has recently been proposed for analog optical fronthauling in centralized radio access networks (CRANs) to avoid the bandwidth expansion of digital fronthauling (e.g., common public radio interface protocol, CPRI). At the transmitter, the radio-signal is mapped onto the duration of an on/off keyed optical signal, while at ...

Effective Indoor Coverage via Radio-Over-Cable Fronthauls: Analog Fronthauls Come of Age
IEEE Vehicular Technology Magazine, 2020This article considers a radio-over-cable (RoC)based analog link on a local area network (LAN) cable [e.g., category (CAT) 5] as the last hop of the fronthaul for indoor mobile service coverage. We first present state-of-the-art mobile systems with RoC-based fronthauls and then discuss a number of critical issues regarding real implementation.

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

This letter studies a joint design of transmit beamforming and fronthaul compression for the uplink cloud radio access network (C-RAN) with intelligent reflecting surface (IRS) aided wireless fronthauling. In C-RAN, a number of users communicate with baseband unit (BBU) pool through multiple remote radio heads (RRH), wherein RRHs compress the received ...
