Design of C-V2X CAM/DENM Separate Resource Pool

Abstract

With the popularization and revolution of wireless networks and autonomous driving, cellular-vehicle-to- everything (C-V2X) has become a hot research scale, which profoundly affects the way people travel and mobility by improving road safety and providing efficient driving paths. The type of data packets used to communicate in the C-V2X includes periodic and aperiodic messages and they use the same resource pool. In this work, we proposed a novel method that can support dividing the whole resource pool for the periodic and aperiodic messages. This method can ensure that the packet reception ratio of aperiodic messages is maximized while maintaining the stability of periodic message receiving performance. And based on the simulations, we concluded the proposed method can provide better performance. © 2022 IEEE.
