Evolution in 5G NR V2X Technology - A Detailed Look at Enhancements in 3GPP Releases 17 and 18

초록

The evolution of Vehicle-to-Everything (V2X) communication within the 3rd Generation Partnership Project (3GPP) framework has progressed from Long Term Evolution Vehicle-to-Everything (LTE-V2X) to Fifth Generation New Radio Vehicle-to-Everything (5G NR-V2X), aiming to support advanced V2X applications. Releases 17 and 18 improve 5G NR-V2X with multicast Uu transmission for better resource use and advanced V2X application like map updates and High Definition (HD) video downloads. They also integrate Artificial Intelligence and Machine Learning (AI/ML) for enhanced performance and efficiency, using dynamic resource selection and power consumption reduction strategies. These enhancements signify a transition towards more advanced and efficient V2X systems capable of supporting diverse cooperative automated driving applications. Keywords-- 5G NR-V2X, 5G Advanced, V2X communication, 3GPP Release 17, 3GPP Release 18.
