Suggestions on Potential Solutions to C-RAN

This document of „Suggestions on Potential Solutions to C-RAN“ studies key technologies critical for C-RAN realization. Starting from scenarios suitable for C-RAN deployment, major functionalities of C-RAN are presented, some of which distinguish C-RAN from traditional systems. To fullfill the critical functions and to exploit the potentials of C-RAN such as resource sharing, possible solutions are studied and suggested. The document ends with suggestion on how traditional RAN could evolve to C-RAN step by step and the trend on fiber transport networks.
