Modern transportation today encounters great challenges in safety, mobility, environment, and space. Vehicle to Everything (V2X), the umbrella term including vehicle to vehicle (V2V),  vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), vehicle to cloud (V2C), vehicle to sensor (V2S), etc., will be a game changer for modern transportation. In this talk, we brief a few major challenges of V2X wireless communication systems and the 5G New Radio (NR) based C-V2X.  Then we introduce our enhanced C-V2X medium access solutions to achieve higher reliability and scalability, and a new communication technology we recently developed to allow concurrent, collision-free transmissions. Hope they inspire more research efforts and advances, contributing to the new era of V2X-enabled Intelligent Transportation.
