Enhancing C-V2X Vehicle Platooning: A Dual-Strategy of Time Synchronisation and Partition-Based Scheduling

There is clear evidence indicating that the standardized Sensing-Based Semi-Persistent Scheduling scheme in Out-of-coverage possesses specific vulnerabilities. This unsatisfactory performance lies in the absence of coordination in channel scheduling and transmission time. Specifically, the determination to re-assign a resource after the reservation period expires is currently based on a random selection process, without consideration of the actual interference encountered by the utilized resources. In this study, a novel scheme is proposed to markedly improve the random selection method for vehicle positioning.
