technical field

It is backward compatible and cannot work alone. Therefore, the communication scenario of the future Internet of Vehicles is as shown in Figure 1. There are existing LTE-vehicle and everything interconnected V2X (Vehicle to Everything, V2X) terminals in the network, as well as new wireless (New Radio, NR)-V2X Terminals, among which, V2X Internet of Vehicles communication is mainly divided into three categories: Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I) and Vehicle to Pedestrian (V2P) . Therefore, a terminal that supports NR-V2X uses the PC5 interface when communicating directly with a terminal that only supports LTE-V2X, and a new wireless direct link is used when communicating directly between two terminals that support NR-V2X Road (NR-Sidelink) interface.

When two types of IoV terminals exist in the network at the same time, in related technologies, the terminals cannot understand the capabilities of the other party during direct communication, so communication will be invalid due to the mismatch of terminal capabilities during communication.
