This course provides a thorough overview of the Next-Generation Radio Access Network (NG-RAN) which is part of the 3GPP 5G System. The focus is on Standalone (SA) operation with NG-RAN connected to the 5G Core Network.
The course starts with a brief introduction to the 5G System, but focuses on the nodes/functions, interfaces, protocols and procedures in the NG-RAN. The course also describes dual connectivity as well as various NG-RAN implementations such as C-RAN, O-RAN (from O-RAN Alliance) and IAB (Integrated Access and Backhaul).
This course also exists in a shorter version, 5G NG-RAN in Half a Day, and a much shorter version, 5G NG-RAN in an Hour.

Prerequisites
Knowledge of LTE/4G is required. Basic knowledge of the overall 5G System is recommended. Good 5G background knowledge is provided e.g. by Apis’ 5G System Overview course.
