This paper presents OpenCV2X, the first publicly available, open-sourcesimulation model of the Third Generation Partnership Project (3GPP) Release 14Cellular Vehicle to Everything (C-V2X) sidelink) This model forms the basis for 5GNR Mode 2 under later releases . We show how the currentsidelink scheduling mechanism performs poorly when scheduling applications with highly aperiodic communication characteristics, such as ETSI CooperativeAwareness Messages . We then provide the first indepth evaluation ofdedicated per-packet scheduling mechanisms, in contrast to schemesthat parameterise the existing algorithm . Finally, we analyse how such scheduling mechanisms might co-exist .
