Project RAN Evolution: Further Study on Critical C-RAN Technologies

This document aims to provide the industry the guidance on solution design of mainly three key technologies which are critical to C-RAN’s realization: function split solutions for fronthaul design, efficient DU pool design and IT virtualization implementation for C-RAN. In addition, three prototypes are also presented to demonstrate either the feasibility and performance of the technologies or the advanced features that C-RAN can support, e.g. CoMP.
