Abstract

The invention provides a V2X communication method and device. The method comprises the following steps: terminal equipment acquires a first corresponding relationship between service information and afirst transmission parameter, wherein the service information comprises any one or more of the following information: one or more of the following information; service recognition, pPPP of traffic, the PPPR or QFI of the service is realized; wherein the first transmission parameter comprises any one or more of the following parameters: one or more of the following parameters; wherein the information of the allowed SCS, the duration of the maximum PSSCH, the information of the allowed cell, the information of the allowed frequency point, the minimum block error rate information, the information of the allowed first type of resources, the information of the allowed second type of resources, the information of the allowed MCS table and the information of the allowed air interface are obtained; and acquiring transmission resources and second transmission parameters corresponding to the transmission resources, and allocating the transmission resources to the data packets corresponding to the service information according to the first corresponding relationship and the second transmission parameters corresponding to the transmission resources. According to the method, different transmission parameters can be selected for the data packets corresponding to different services / PPPP / PPPR / QFI according to the service information of the data packets, so that the transmission parameters canmeet the service requirements.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a V2X communication method and device. Background technique [0002] Vehicle-to-everything (V2X) technology realizes the communication between vehicles and the outside world. V2X includes vehicle-to-road infrastructure (V2I) services, vehicle-to-network (V2N) services, vehicle to pedestrian; V2P) business, vehicle-to-vehicle (vehicle to vehicle; V2V) business. Based on the V2X of Long Term Evolution (LTE), there are two air interfaces: Uu and PC5. The Uu air interface is used for communication between terminal equipment and network equipment, and the PC5 air interface is used for sidelink (sidelink) between terminals. ) communication, both of the above two air interfaces can be used to transmit V2X data. [0003] The PC5 air interface supports two resource allocation modes: mode 3 and mode 4. In mode 3, the terminal device uses dedicated resources for communication. T...
