Abstract
Disclosed are a device discovery method for device-to-device (D2D) communication in a wireless access system supporting D2D communication and a device therefor. Particularly, the device discovery method can comprise the steps of: enabling a first device in an idle mode to receive a paging message from a base station; enabling the first device to switching to an active mode if the paging message indicates the first device; enabling the first device to monitor a discovery signal transmitted from a second device if the paging message indicates that the first device operates in a reception mode with respect to transmission and reception of the discovery signal; enabling the first device to perform a random access procedure with the base station if the first device receives the discovery signal; enabling the first device to perform a connection establishment procedure with the base station after completing the random access procedure; and enabling the first device to transmit, to the base station, a D2D discovery report after completing the connection establishment procedure.
