The present invention relates to a method for preventing a peer discovery signal collision which may occur in a device-to-device (D2D) communication system and a wireless device using the same. According to an embodiment of the present invention, a method for communication between wireless devices by using a peer discovery slot comprises the following steps of: transmitting a first peer discovery signal through a first peer discovery channel selected from multiple peer discovery channels; receiving a second peer discovery signal transmitted by an adjacent wireless device; confirming a second peer discovery channel from which the second peer discovery signal is detected among the multiple peer discovery channels; and transmitting a feedback signal through a response channel corresponding to the second peer discovery channel among multiple response channels.
