A Representation of 3GPP 5G-V2X Sidelink Enhancements in Releases 14, 15, 16, and 17

Vehicle-to-Vehicle (V2V) communication is considered the enabler of road safety, traffic efficiency, and compatibility for drivers, passengers, vulnerable users. The evolution 5G V2X enhances physical layer LTE in terms resource allocation, frame structure, many more. amendments are to enable exchange safety advanced driving services within a geographical area. introduction 25 use cases 3GPP Release 15 standard with different quality service (QoS) requirements high demand data rates makes it possible enhancements. Delivering established becomes challenge 5G-V2V communication. 14 release mark V2X, while 16 highlights advancements NR services, 17 focuses on future enhancements applications Machine Learning (ML) Artificial Intelligence (AI). This study examines sidelink communication, allocation V2V 5G-V2V, enablers such as Network Slicing (NS) recent capacity studies employing two enablers. In Sidelink Physical Shared Channel (PSSCH) responsible broadcasting various messages using waveforms. PSSCH broadcast Cooperative Awareness Messages (CAM), Decentralized Environmental (DENM), Light Detection Ranging (LIDAR) contents environmental perception, sensor DATA intention, challenge. this by providing mathematical model V2I links network mode selection Poisson point process line circular region.
