Chapter 11: NR URLLC

Abstract

In this chapter a general overview of NR is given with emphasis on the evolution from LTE. With this as base, the focus is set on the parts of the design of NR introduced to enable Ultra-Reliable Low-Latency Communications, going from the physical layer design up to procedures for idle and connected modes.
