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 Generation 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。
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-toinfrastructure,and vehicle-to-pedestrian communications.3rd Generation Partnership Project(3GPP)has finished research 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 communication(ISAC),artificial intelligence and machine learning(AI/ML).The development trends of sidelink communication technology in C-V2X were firstly introduced.Then,the key evolution points of 3GPP Release 18 sidelink communication technology were discussed.Finally,considering the research on 6G technology in 3GPP Release 19,a perspective on the standard future development direction of C-V2X was provided.
