Abstract: The present invention relates to a method for performing a D2D discovery and a terminal using the same. Particularly, the present invention relates to a method for performing a D2D discovery, which compares a congestion level of another discovery slot selected randomly or according to a preset pattern with a threshold or a congestion level of a current discovery slot and determines a discovery slot to transmit a discovery message and a transmission period of the discovery message according to a result of the comparison, and a terminal using the same. The present invention relates to a method for performing a D2D discovery using discovery resources including a plurality of discovery slots, and a terminal performing the same, the method comprising the steps of: broadcasting a discovery message by using a first discovery slot; comparing a congestion level of a selected second discovery slot with a predetermined congestion level value; determining a discovery slot to broadcast the discovery message on the basis of a result of the comparison; and broadcasting the discovery message by using the determined discovery slot.
