Abstract

The invention discloses a method and a device for transmitting D2D data based on a resource mode. The method for transmitting D2D data based on a resource mode includes a step of determining a selected D2D data transmission resource for transmitting a D2D data transmission unit; a step of transmitting a D2D data transmission unit through the selected D2D data transmission resource; wherein, the selected The D2D data transmission resource is indicated based on the change mode of the basic mode, and the change mode can be determined based on information about the number of D2D data transmission resources used to transmit one D2D data transmission unit, information about the selected Information about the number of D2D data transmission resources in the basic mode, information about the number of unit D2D data transmission resources in the basic mode, and information about the number of selected unit D2D data transmission resources.

Description

technical field [0001] The present invention relates to wireless communication, and more specifically, to a method and device for transmitting D2D (device-to-device, device-to-device) data based on a resource mode. Background technique [0002] The amount of data transmitted through wireless communication is gradually increasing. However, the frequency resources that service companies can provide are limited and have reached a saturated state. Therefore, mobile communication companies are constantly developing technologies for discovering new frequencies and improving frequency utilization efficiency. One of the technologies currently being actively researched is a D2D (Device-to-Device, Device-To-Device) communication technology as a solution for solving the phenomenon of insufficient frequency resources and creating a new mobile communication service. [0003] D2D communication refers to a technology in which geographically adjacent terminals directly transmit or receive ...
