Course Objectives

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 course is based on the 3GPP Release 15 version September 2018 and it is equipment vendor independent.
