5G Air Interface Non-Standalone Operation

The 5G air interface is a key part of the 5G system which will facilitate Enhanced Mobile Broadband and Ultra Reliable Low Latency Communication, as well as the support of Massive IoT. The course focuses on the initial NSA (Non Stand Alone) operation, also known as EN-DC. In so doing it identifies the 5G NR (New Radio) air interface, from the physical layer operation to higher layer support of services. In addition, modification to existing LTE procedures are also examined, as well as NSA based mobility.
