Abstract

The present invention provides a D2D communication method and device. By carrying the service period indication information of the UE in the D2D data and sending it to the receiving end, the receiving end can know the transmission resource occupation of the UE through listening, etc., including service Period and occupied time-frequency resource location, etc., so as to determine idle transmission resources, and select the idle transmission resources for D2D communication, so as to avoid waste of transmission resources and improve the utilization rate of transmission resources.

Description

technical field [0001] The present invention relates to the field of Internet of Vehicles, in particular to a D2D communication method and device. Background technique [0002] In recent years, the automobile network has attracted more and more attention. Through the vehicle-to-vehicle communication or the communication between the vehicle and the roadside unit, the safety and reliability of road traffic can be improved, and the traffic efficiency can be improved. In the Internet of Vehicles, in order to ensure the safe driving of vehicles, periodic interactive information is required between vehicles, including the position, speed, status and other information of the vehicle, which is broadcast to surrounding vehicles through a single hop. For this purpose, D2D ( Device to Device, end-to-end) communication, regards the vehicle as a UE (User Equipment, user equipment) for inter-vehicle communication. [0003] According to different transmission modes, D2D communication is s...
