Course Description
The 5G System Overview provides an overview of the emerging 5G system as defined and standardized by 3GPP, other SDOs (standard development organizations) as well as various industry players and initiatives. The course accounts for the various aspects of the 5G System (Access Network, 5G Core), nodes/functions, interfaces / reference points, basic procedures and main architectural ideas. The course explains concepts important to 5G like NFV/SDN and network slicing, and how these are used to make the 5G System more efficient and flexible than earlier generations of 3GPP networks. The ITU 5G Use Cases (eMBB, URLLC and mMTC) are outlined in terms of services and technical aspects. The course gives an overview of the 5G Radio Access Network including 5G New Radio (NR) and integration with LTE.
