    Abstract: The purpose of the present invention is to provide a method for increasing data transmission efficiency when performing packet duplication. A method for a terminal in a wireless communication system according to the present invention comprises the steps of: performing protocol data convergence protocol (PDCP) duplication in which an identical PDCP protocol data unit (PDU) is transmitted to a base station through each of a first logical channel and a second logical channel; when a request for retransmission of the PDCP PDU which has been transmitted through the second logical channel is received from the base station, retransmitting the PDCP PDU to the base station; and when the PDCP PDU has been retransmitted a predetermined number of times or more, receiving, from the base station, information indicating deactivation of the PDCP duplication.

    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.
