Cellular Vehicle-to-Everything (C-V2X) Testing: From Theory to Practice

Currently, the research on the cellular vehicle-to-everything (C-V2X) technology has obvious challenges and limitations of security, reliability, and consistency. This article aims to provide insights for a comprehensive understanding of C-V2X testing from the perspectives of communication performance, functional application, and security, which can support the C-V2X network softwarization and management. First, we review the recent progress of C-V2X testing on wireless communications, including antenna and propagation, protocol conformance, communication performance, and interoperability testing. Second, we discuss the current work in the area of C-V2X testing on functional applications, including functional environment and positioning performance testing. Third, we review the recent advance in C-V2X testing on security, including vehicular gateway and penetration security testing. Finally, open issues and promising future research directions for C-V2X testing are outlined.
