The 5G NR Air Interface course offers a complete understanding of the radio interface in 5G NR technology. A general characteristic of 5G is presented with its architecture, interfaces and protocols. The course focuses on the physical channels structure and their processing. It also presents physical layer procedures including random access, power control, HARQ related to downlink and uplink transmission, massive MIMO and beamforming. The algorithms and procedures of idle mode behaviour and handover process are also discussed.

The 5G NG-RAN Signalling course offers a complete understanding of all signalling protocols implemented in the NG-RAN. The course presents the 5G architecture with its nodes, interfaces and protocol stacks and describes protocols through functions and and services they provide. The course focuses on the details of the NR interface signalling exchanged between the UE and the network, however the most important aspects of other NG-RAN interfaces are also covered. Most important network procedures, such as signalling connection establishment, registration, service request and handover are discussed and presented on signalling diagrams.
The course is based on the 3GPP Release 15 version September 2018 and it is equipment vendor independent.
