The cellular industry is gearing up for 5G. The industry is planning to support a variety of new and exciting services such as Augmented Reality (AR)/Virtual Reality (VR), hologram videos, and self-driving cars. Such services require a wide range of network capabilities to support a variety of consumer devices and Internet-of-Things (IoT) devices. This course takes an in-depth look at the 5G NG-RAN architecture and major operations that enable a 5G network to support the target 5G services. Various aspects of the NG-RAN are described. Registration and session setup are discussed along with a look at network slicing. The data transfer in both downlink and uplink is described. Mobility in connected, inactive, and idle modes is discussed. Finally, the status of 5G in in the industry is summarized.

This detailed technical course is intended for engineering and related job functions who need to get an in-depth understanding of 5G NG-RAN architecture and operations.

After completing this course, the student will be able to:
■ Illustrate the architecture of the NG-RAN
■ Describe the frame structure with numerology of the air interface
■ Summarize architecture enhancements such as Cloud-RAN and Dual Connectivity
■ Identify key steps of network acquisition, random access, and connection setup
■ List main steps of registration, network slice selection, and session setup
■ Give examples of QoS parameters in 5G
■ Explain how data is transferred in the downlink and the uplink
■ Differentiate between the connected mode mobility and the idle/inactive mode mobility
