A Virtual Driving Testing Method for C-V2X Performance Evaluation

As one of the most promising on-board applications, C-V2X (Cellular Vehicle-to-Everything) technology is designed to improve road safety and efficiency. How to effectively evaluate the performance of C-V2X products is also one of concerns of the industry. In this paper, a novel performance test method which called virtual driving test (VDT) is proposed, based on which the signal propogation environment on real roads can be reproduced in laboratories. Test results show that the deviation of RSRP and SINR between outdoor environment and the VDT system is less than 1dB, delay deviation is less than 1ms, and packet loss rate (PLR) curves almost coincide.
