Abstract

C-V2X includes two solutions: Uu interface based C-V2X and PC5 interface based C-V2X. The Uu interface based C-V2X has challenges such as latency and message congestion. This paper introduces a risk filtering algorithm through the V2X capability classification, and proposes a software-defined C-V2X solution (SUC-V2X) to systematically solve problems of Uu interface based C-V2X. This article further verifies the performance of the solution.
