US 10,383,089 B2 · Method for transmitting device to device communication signal through unlicensed band in wireless communication system and apparatus therefor

Abstract

Disclosed is a method for transmitting a device to device (D2D) signal by a terminal in a wireless communication system. More particularly, the method for transmitting a D2D signal comprises the steps of: configuring a resource pool comprising a plurality of resource units for transmitting the D2D signal; determining the number of transmission attempts for the D2D signal; selecting as many resource units as the number of transmission attempts from among the resource units in the resource pool; and determining whether the selected resource units are in the busy state or in the idle state over time, and when it is determined that the selected resource units are in the idle state, transmitting the D2D signal to a target terminal.
