Abstract

Embodiments of the invention provide a D2D data package transmission method and apparatus, transmitted resource allocation methods and apparatuses. The method comprises the steps of setting a plurality of data package copies of a D2D data package; determining transmitting frequency of each data package copy, wherein transmission frequencies of all data package copies are different; and transmitting each data package copy at corresponding transmission frequency. According to the D2D data package transmission method, small data transmission time delay can be realized, so that a good time delay control purpose can be achieved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a D2D data packet transmission method, transmission resource allocation method and device. Background technique [0002] The fifth-generation mobile communication technology (5G) is the next important stage of civilian mobile communication technology. Various countries and technical organizations around the world have carried out a lot of research; as a key candidate technology for 5G, D2D (Device-to-Device) To-device communication) has the potential to improve system performance, enhance user experience, and expand cellular communication applications, so it has received widespread attention. [0003] The Internet of Vehicles is a main application scenario of D2D. In the application scenario of D2D Internet of Vehicles, the PC5 interface is used for communication between the vehicle (V-UE) and the roadside unit (RSU) and between the V-UE. The PC5 interface is defined by 3...
