Contents

The course starts with a general description of the 5G System elements and principles, various RAN — core and dual connectivity options, followed by a discussion of aspects of the new air interface and the nodes, interfaces and procedures in the NG-RAN. Some interworking aspects with E-UTRA radio and non-3GPP access are also discussed.

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.

Note: The course is under development and the content may be subject to changes.
