Disclosed is a method for performing, by a device, device-to-device direct communication in a wireless communication system. In particular, the method comprises the steps of: transmitting a device-to-device direct communication signal via a first resource block having a resource structure for device-to-device direct communication at a first point in time; and transmitting the device-to-device direct communication signal via a second resource block having a resource structure for the device-to-device direct communication at a second point in time, wherein the first resource block and the second resource block are defined by a time unit index and a resource unit index, respectively, and wherein the time unit index of the second resource block is determined on the basis of the resource unit index of the first resource block index, and the resource unit index of the second resource block is determined on the basis of the time unit index of the first resource block index.
