Communication method and related equipment

Abstract

The invention provides a communication method for data transmission in Internet of Vehicles V2X and related equipment. The method comprises the following steps: 1, ; the first terminal device receivesfirst information from the first wireless access network device, wherein the first information comprises service information of a service of the first terminal device and a resource configuration mode of a sidelink; wherein the service information and the resource configuration mode of the sidelink have a corresponding relationship, the first terminal device transmits data corresponding to the service information on a transmission resource of the sidelink configured according to the resource configuration mode based on the corresponding relationship, and the service information can be reliability information. By implementing the method, the transmission of the service data with high reliability requirement can be ensured, and the transmission reliability requirement and the transmission time delay of the service data can also be considered.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a communication method and related equipment for data transmission in the Internet of Vehicles. Background technique [0002] The Internet of Vehicles V2X (vehicle to X) is the key technology of the intelligent transportation system. It is considered to be one of the fields with the most industrial potential and the clearest market demand in the Internet of Things system. It has wide application space, great industrial potential, and strong social benefits. It is of great significance to promote the innovation and development of the automobile and information communication industry, build new models and formats of automobile and transportation services, promote the innovation and application of autonomous driving technology, and improve traffic efficiency and safety. The Internet of Vehicles generally refers to the provision of vehicle information through s...

Problems solved by technology

At this time, since the resources of each terminal device are independently selected, there is no need to exchange signaling with network devices, so the transmission delay of sending data in mode 4 may be shorter than that in mode 3. However, due to different terminals When selecting resources independently, different terminal devices may choose the same resource to send data, so transmission collisions may occur

[0006] At present, there is no good mechanism to take into account the transmission reliability requirements and transmission delay requirements of business data, and there is no good mechanism to rationally or evenly use the transmission resources of the sidelinks configured according to two different resource allocation methods.
