摘要
随着智能交通系统的快速发展,面向蜂窝车联网(cellular vehicle-to-everything,C-V2X)的直连通信技术已成为实现车辆间、车辆与基础设施间以及车辆与行人间通信的关键.第三代合作伙伴计划(3rd Gen-eration Partnership Project,3GPP)目前已经完成了对直连通信增强技术的研究,旨在适应车联网服务的多元化需求,并且正在积极推进通信感知一体化(integrated sensing and communication,ISAC)、人工智能/机器学习(artificial intelligence/machine learning,AI/ML)等6G演进技术的研究和标准化工作.首先介绍了蜂窝车联网直连通信技术的发展趋势,进而探讨了3GPP R18直连通信技术的关键演进方向,最后结合3GPP R19中6G前瞻性技术的研究方向,对蜂窝车联网的未来标准发展方向进行展望.
Abstract
With the rapid development of intelligent transportation systems,sidelink communication technology for cellular vehicle-to-everything(C-V2X)has become the key technology to enable vehicle-to-vehicle,vehicle-to-infrastructure,and vehicle-to-pedestrian communications.3rd Generation Partnership Project(3GPP)has finished re-search on sidelink communication technology enhancement,aiming to meet the diverse needs of V2X services,and is actively advancing research and standardization on 6G evolution technologies such as integrated sensing and commu-nication(ISAC),artificial intelligence and machine learning(AI/ML).The development trends of sidelink communi-cation technology in C-V2X were firstly introduced.Then,the key evolution points of 3GPP Release 18 sidelink com-munication technology were discussed.Finally,considering the research on 6G technology in 3GPP Release 19,a per-spective on the standard future development direction of C-V2X was provided.
