5G NR Air Interface - Course Overview

Understanding Protocols and Design Principles

This course provides an in-depth description of 5G New Radio (NR) technology as defined by 3GPP standards and specification. The content and flow are structured to introduce NR air interface with a focus on technical design principles and their impacts on performance and deployments. 

Starting with a brief background on the 5G requirements, standardization landscape and roadmap,  the course presents the end to end 5G system, including  NG-RAN and 5GCore, architecture and air interface protocol structure. The discussion is then followed by a detailed description of the physical layer including time and frequency resource structure, channelization, scheduling, and transmission protocols. 

The course also presents the step by step process followed by a UE from downlink synchronization to uplink access and operation in connected mode under power saving, mobility and beam management. Given NR has the same technical foundation as LTE and is excepted to co-deploy with LTE for many years the course also opportunistically makes comparisons with LTE system. 

The contents of this course are kept up to date with the evolution of standards and may be adjusted to best reflect the state of NR technology.
