Abstract

The invention provides a method and a device for transmitting V2X service data. The method includes the following steps: acquiring the position information of a first terminal; determining a service receiving area of a V2X service data packet of the first terminal according to the position information of the first terminal; and sending V2X service data in the V2X service data packet of the first terminal to at least one second terminal in the service receiving area of the first terminal through a receiving base station in the service receiving area, wherein the V2X service data packet includes a packet header and V2X service data sent by the first terminal. Through the scheme of the invention, downlink congestion can be reduced, and the capacity of the system can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for transmitting V2X service data. Background technique [0002] V2X (Vehicle-to-Everything) communication is a hot topic in the field of communication at present. V2X communication mainly includes three aspects: [0003] V2V (Vechile-to-Vechile, vehicle-to-vehicle): communication between OBU (On Broad Unit, vehicle-mounted unit) on the vehicle; [0004] V2I (Vechile-to-Infrastructure, vehicle to network): communication between the vehicle and RSU (Road Side Unit, roadside equipment); [0005] V2P (Vechile-to-Pedestrian, vehicle to pedestrian): Communication between vehicles and pedestrians. [0006] For V2X, if V and X use the communication method via the network, it can be called V2X communication via the network (hereinafter referred to as Uu V2X for short); if V and X use the direct communication method, it can be called V2X direct commu...
