Abstract

一种V2X通信的方法、设备及系统，涉及无线通信技术领域，用以解决决目前V2X通信过程中只能保证优先级较高的数据包传输可靠性的问题。其中，该方法包括：终端获取V2X数据包的优先级与V2X通信参数取值范围的对应关系，并根据V2X数据包的优先级以及对应关系，确定V2X数据包的V2X通信参数取值范围，然后选择一个V2X通信参数值；最后，根据选择的V2X通信参数值，传输V2X数据包。这种技术方案由于终端基于V2X数据包的优先级与V2X通信参数取值范围的对应关系，在无线资源上传输V2X数据包，因此，当传输资源紧张时，能够通过配置该对应关系，在一定程度上提高优先级较低的数据包的传输可靠性。
