D4.1 State-of-the-Art Review and Initial Definition of BeGREEN O-RAN Intelligent Plane


BeGREEN D4.1 presents an exhaustive SotA review focusing on relevant specifications, developments and projects related to RAN Intelligent Controllers (RIC) and their utilisation for the implementation of intelligent and automated control loops. After this, open-source, commercial and simulated/emulated implementations are described. This document presents the design principles of a BeGREEN O-RAN (Open-RAN) "Intelligent Plane" that allows to introduce Artificial Intelligence (AI) and Machine Learning (ML) control and management plane functions to reduce the overall energy consumption of the RAN infrastructure. It also covers the relationship of the BeGREEN Intelligent Plane with the rest of BeGREEN components and the O-RAN architecture, extending the previous work done in BeGREEN D2.1 [1].
