Phase and Time Synchronization for 5G C-RAN: Requirements, Design Challenges and Recent Advances in Standardization
Journal Title: EAI Endorsed Transactions on Industrial Networks and Intelligent Systems - Year 2018, Vol 5, Issue 15
Abstract
Cloud-RAN is one of the key enablers for 5G. In this paper we present the importance of network synchronization for the fronthaul architectures. The term network synchronization refers to the distribution of time and frequency among spatially distributed remote nodes. Underlining this point, we investigate the requirements and network design challenges to precisely synchronize the 5G C-RAN radio units. We conclude the article by pointing-out the recent advances in standardization together with describing the proposed practical solutions and methodologies to practically overcome these challenges in real networks.

An Application of SMC to continuous validation of heterogeneous systems
This paper considers the rigorous design of Systems of Systems (SoS), i.e. systems composed of a set of heterogeneous components whose number evolves with time. Such components cooperate to accomplish functions that they...
A Survey of System Level Power Management Schemes in the Dark-Silicon Era for Many-Core Architectures
Power consumption in Complementary Metal Oxide Semiconductor (CMOS) technology has escalated to a point that only a fractional part of many-core chips can be powered-on at a time. Fortunately, this fraction can be increa...
Security and Privacy in Online Social Networks: A Survey
The Online Social Networks (OSN) open a new vista serving millions of users and have reshaped the way people interacts. Unfortunately these networks are an emerging platform for cybercrimes such as sending malicious URLs...
Improving ns-3 Emulation Support in Real-World Networking Scenarios
A common problem in networking research and development is the duplicate effort of writing simulation and implementation code. This duplication can be avoided through the use of fast-prototyping methodologies, which enab...
