The call for high performance vehicular-to-everything (V2X) connectivity for automotive applications has spurred the considerable development of several standards, where the 5G New Radio (NR) is playing definitely an essential role. In this paper, after briefly reviewing the basics of the NR physical layer, we first evaluate by simulation the performance of NR-based V2X communication links for the NR modulation and coding scheme (MCS) options, and then, such outcomes are exploited to perform the link design for realistic wireless scenarios. Our results show considerable performance gains when the proper MCS is adopted, thus motivating the need for suitable resource allocation algorithms.

Abstract
The call for high performance vehicular-to-everything (V2X) connectivity for automotive applications has spurred the considerable development of several standards, where the 5G New Radio (NR) is playing definitely an essential role. In this paper, after briefly reviewing the basics of the NR physical layer, we first evaluate by simulation the performance of NR-based V2X communication links for the NR modulation and coding scheme (MCS) options, and then, such outcomes are exploited to perform the link design for realistic wireless scenarios. Our results show considerable performance gains when the proper MCS is adopted, thus motivating the need for suitable resource allocation algorithms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
