      5g air interface

      The 5G air interface is a key part of the 5G system which will facilitate Enhanced Broadband and Ultra Reliable Low Latency Communication, as well as the support of Massive IoT (Internet of Things). This course focuses on 5G Phase 1. In so doing, both SA (Standalone) and NSA (Non Standalone) operation are discussed. The course details all aspects, from the physical layer channel and reference signals, through to scheduling and analysis of NR RRC signalling utilized to configure the NR air… Show more The 5G air interface is a key part of the 5G system which will facilitate Enhanced Broadband and Ultra Reliable Low Latency Communication, as well as the support of Massive IoT (Internet of Things).
