【Abstract】 B5G/6G cellular Internet of Vehicles is an important information technology means to build a modern intelligent transportation system and break through the current traffic dilemma. Intelligent access and dynamic management of heterogeneous and multi-resources centered on vehicle users are the focus of academic frontiers and industrial applications of B5G/6G cellular Internet of Vehicles. Analyzed the core challenges of user-centric B5G/6G cellular Internet of Vehicles intelligent access and dynamic resource management; introduced representative cutting-edge technology methods of user-centered B5G/6G cellular Internet of Vehicles intelligent access and dynamic resource management; discussed The user-centered B5G/6G cellular Internet of Vehicles new network architecture, flexible access management, flexible resource adaptation, on-demand business services and other important research directions; finally, the user-centered B5G/6G cellular Internet of Vehicles intelligent access It summarizes and looks forward to the future development direction of resource management.
【Key words】 B5G/6G; Cellular Internet of Vehicles; decoupling of uplink and downlink; resource management; digital twin; no cellular network
0 Development background of user-centered B5G/6G cellular Internet of Vehicles
As of the end of 2021, the number of cars in my country will reach 395 million, of which the number of new energy networked vehicles will reach 7.84 million. Car ownership continues to grow at a high level, and the growth rate of new energy vehicles is as high as 59.25% year-on-year [1]. The problems of road safety and traffic congestion caused by so many cars are becoming more and more serious. Vehicle-to-Everything (V2X, Vehicle-to-Everything) has become an important technology to solve current traffic problems and realize traffic intelligence, and it is also the key to enabling autonomous driving. One of the techniques [2]. There are two main types of current IoV technologies: Dedicated Short-Range Communication (DSRC, Dedicated Short-Range Communication) and C-V2X, Cellular V2X [3-4]. Compared with DSRC technology, cellular vehicle networking technology has the advantages of higher transmission rate, wider coverage, and higher mobility. Cellular Internet of Vehicles technology is an Internet of Vehicles technology based on cellular networks, and its development is also closely related to the development of cellular networks. With the continuous evolution of cellular networks, cellular Internet of Vehicles technology has also developed LTE-V2X
