This paper is concerned with the key features and fundamental technology
components for 5G New Radio (NR) for genuine realization of connected and
cooperative autonomous driving. We discuss the major functionalities of
physical layer, Sidelink features and its resource allocation, architecture
flexibility, security and privacy mechanisms, and precise positioning
techniques with an evolution path from existing cellular vehicle-to-everything
(V2X) technology towards NR-V2X. Moreover, we envisage and highlight the
potential of machine learning for further enhancement of various NR-V2X
services. Lastly, we show how 5G NR can be configured to support advanced V2X
use cases in autonomous driving

5G New Radio (NR) is touted as a pivotal enablingtechnology for the genuine realization of connected and cooperativeautonomous driving. Despite numerous research efforts inrecent years, a systematic overview on the role of 5G NR in futureconnected autonomous communication networks is missing. To fillthis gap and to spark more future research, this paper introducesthe technology components of 5G NR and discusses the evolutionfrom existing cellular vehicle-to-everything (V2X) technologytowards NR-V2X. We primarily focus on the key features andfunctionalities of physical layer, Sidelink communication and itsresource allocation, architecture flexibility, security and privacymechanisms, and precise positioning techniques. Moreover, weenvisage and highlight the potential of machine learning forfurther performance enhancement in NR-V2X services. Lastly,we show how 5G NR can be configured to support advancedV2X use cases
