This course takes an in-depth look at the 5G NR Air Interface and key operations that enable a 5G network to support the target 5G services. Key features of 5G NR such as flexible frame structure, DL and UL channels and signals and their functions are described in detail. The data transfer in both downlink and uplink, handovers and idle modes operations are discussed. This training is delivered in a blended form with elements of self-paced and instructor led to enhance the learning experience and effectiveness.

RAN design and performance engineers and related job functions.

After completing this course, the student will be able to:
■ List 5G requirements and identify 5G NR features to meet these requirements
■ Describe the frame structure with numerology of the air interface
■ List downlink and uplink signals and channels and describe their function
■ Identify key steps of network acquisition, random access, and connection setup
■ Explain how data is transferred in the downlink and the uplink
■ Step through the handover and idle/inactive mode operations
