5G NR Air Interface Overview - Part II
5G_102Bd | On-Demand | 5G Access | 1
Course Duration: 1 hour
5G promises to enable a variety of new services, ranging from high-speed, high-capacity broadband access to ultra reliable low-latency communications to massive machine-type communications. To deliver on these promises, the wireless network must change, including the devices, the radio interface, the radio access network (RAN), and the core network. Part I of this self-paced course offers a high-level technical overview of 5G NR (New Radio) air interface. Part II covers the flexible numerologies, channels and frame/slot structure, and steps through the life of a 5G UE, concluding with how the technologies and standards converge to meet the performance goals set for 5G.
Intended Audience
This course is designed for a broad audience of wireless network engineers. This includes those in RF, RAN planning, engineering, operations, troubleshooting and support groups.
After completing this course, the student will be able to:
■ Identify key channels and their usage in the downlink and uplink
■ Step through the life of a 5G UE at a high level in non-standalone architecture
■ Step through the life of a 5G UE at a high level in standalone architecture
■ Identify ways in which 5G NR meets the performance goals of 5G
