Survey on Challenges and Solutions of C-V2X: LTE-V2X Communication Technology

In Vehicle-to-Everything (V2X) communications, various tasks have been performed to enable various applications for traffic efficiency, road safety and passenger infotainment. This paper deals with challenges and solutions of the core technology of Cellular V2X (C-V2X) communication that provides high reliability and low latency as it evolves from Long Term Evolution (LTE)-V2X to LTE-enhanced V2X (eV2X) and 5G-New Radio (NR)-V2X. And High throughput communication technologies. Finally, we will further invest gate and discuss research directions that can solve the challenges of C-V2X in the future.
