New radio (NR) is a study item in the 3rd Generation Partnership Project Radio Access network Working Group (3GPP RAN-WG) focusing on a new Radio Access Technology (RAT) for the 5th Generation (5G) cellular communications systems. Together with the next generate core network (NextGen Core), NR fulfills requirements set forth by the International Telecommunication Union (ITU). The IMT-2020 vision for 5G enables a connected society that connects people, things, data, applications, transport systems and cities in a smart networked communications environment. This paper provides an overview of the key design principles and technology components for NR and the main features that distinguish NR from the prior RATs developed by the GPP.
