Performance evaluation on V2X communication with PC5-based and Uu-based LTE in Crash Warning Application

摘要

As well as DSRC, LTE-based solutions have been discussed for Crash Warning Application (CWA), which is one of safety applications with Vehicle-to-Everything (V2X). This paper investigates two methods of LTE-based V2X, - Uu-based LTE-V2X which uses infrastructure and PC5-based LTE-V2X which uses D2D communication. We summarize pros and cons of these two methods for CWA, then, show quantitative performance evaluation results in terms of end-to-end latency. The results show that PC5-based LTE has much better performance than Uu-based LTE although PC5-based LTE requires additional functions to the current LTE.
