Abstract

The novel design of 5G New Radio (NR) air interface on one side and the demand for wider ranges and more types of spectrum access for different verticals and use cases on the other side provides both urgencies and opportunities to realize spectrum reuse through active/passive sharing and coexistence. This tutorial provides a technical overview of key technology components in 5G standards which facilitate spectrum reuse and sharing both within and across different categories of wireless systems. Features such as flexible time and frequency structure and bandwidth parts, resource reservations, Remote Interference Management and NR-unlicensed will be discussed. Also prospect of spectrum reuse between access, back-haul and front-haul and also non-terrestrial networks will be treated. In addition, we will discuss how the 5G NR technical solutions may fit within current and emerging spectrum sharing regulations.
