Abstract Vehicular communication is one of the critical technologies in intelligent transportation system to provide connectivity between vehicles, road side units, and pedestrians. Multiple wireless accessing technologies designed to provide connectivity in vehicular networks such as conventional Wi-Fi, IEEE 802.11p, and cellular communications. Recently, cellular V2X (C-V2X) is standardized and designed by the third generation partnership project (3GPP) for automotive services. C-V2X supports two communication modes through a single platform to provide both Wi-Fi and cellular communication. LTE-V2X is the current 3GPPRelease 14 standard that has many enhancements to provide the new 3GPPRelease 16 for the new 5G radio generation. 5G-new radio (NR) is expected to address the automotive capabilities, improvement, and services for 2020 and beyond. 5G-NR becomes a competitive technology compared with other wireless technologies because of extensive coverage, high capacity, high reliability, and low delay support. In this paper, we propose the Optimizing of 5G with V2X, and analyzing the current V2X standards, introducing the development of 5G, challenges, features, requirements, design, and technologies.

1 Introduction The recent advent of Vehicle-to-Everything (V2X) communications has made it possible to decrease the number of vehicle accidents, and all its associated fatalities [1] dramatically. Not only does the advantages of V2X vehicles confine on shrinking accidents, but it can also assist in traffic management and thus lead to greener vehicles and a decrease in fuel costs [2]. Both safety and other non-safety vehicle applications are presented in intelligent transportation systems (ITS) and the Radio Access Technologies (RATs) used for communication in V2X are Dedicated Short Range Communications (DSRC), which operates in & HyungWon Kim [email protected] 1

the 5.9 GHz band, and the 3rd Generation Partnership Project (3GPP) has presented Cellular-V2X (C_V2X)—a Long Term Evolution (LTE) based RAT—which also operates in 5.9 GHz band in addition to the licensed carriers of cellular operators and can also operate in the absence of the cellular infrastructure in a distributed manner [3]. DSRC is developed based on the IEEE 802.11p standard but is still not widely used in V2X communications due to its poor scalability and its deficiency in performance in a highly mobile environment. C-V2X is the complete integrated road safe
