A research on V2X autonomous vehicles under 5G technology

Abstract

With the continuous development of communication technology, the traditional communication network architecture can no longer meet the demand of telematics technology in the field of autonomous vehicles. The traditional wireless access network architecture needs to evolve quickly to meet the demands of huge traffic, ultra-low latency, and other telematics communication. The commercialization of 5G with its advantages of high reliability and low latency will provide powerful performance and more possibilities for Vehicle-to-Everything (V2X), an essential technology used in automotive communications. This paper introduces the four V2X functional compositions and two major V2X technology standards, namely Dedicated Short Range Communication (DSRC) and Cellular-Vehicle to Everything (C-V2X). Also, we present five remaining limitations of V2X based on the current 5G technology and analyze the specific challenges faced with their possible solutions for the enhancement. Finally, we consider the perspectives of 5G-V2X in autonomous vehicles applications and the analysis on the economy. The continued development of 5G-V2X technology in the field of autonomous vehicles could eventually lead to a significant increase in road safety, a reduction in the number of accidents, and a higher efficiency in driving.
