Abstract

Provided are a data transmission device, and a V2V communication system and method. The data transmission device comprises: a sending module, which broadcasts a first system message, so that a V2V terminal within the coverage of a base station sends a security message and a measurement resource load value; a receiving module, which receives the resource load value sent by a first V2V terminal; and an adjustment module, which adjusts the content of resource control information, so that the sending module broadcasts the adjusted resource control information.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission device, a V2V communication system and method. Background technique [0002] Driving has brought great convenience to people's lives, and the popularity of cars has also increased. However, the rapid increase in the number of vehicles has also caused a series of problems, such as urban traffic congestion, frequent traffic accidents, and poor environmental quality. . Therefore, an intelligent transportation system (Intelligent Transportation System, referred to as: ITS) has become an important development direction of the automobile industry. [0003] Vehicle to Vehicle (Vehicle to Vehicle, referred to as: V2V) communication, as an important communication method in the future ITS, puts forward an idealized idea, that is, vehicles can obtain road condition information or receive information services in time through this V2V communication t...
