Method supporting D2D communication and apparatus therefor in wireless communication system
The present invention relates to a method for transmitting an hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ-ACK/NACK) on the basis of a wide area network (WAN) of a device-to-device (D2D) terminal in a time division duplex (TDD)-based wireless communication system. Specifically, the method comprises the steps of: receiving a downlink HARQ reference configuration for WAN communication; and transmitting a HARQ-ACK/NACK from a downlink HARQ reference configuration-based first uplink subframe, wherein the first uplink subframe is an uplink subframe configured so as to communicate only via WAN.
