Abstract: The present invention discloses a method for managing a device to device (D2D) terminal group in a wireless communication system and an apparatus for the same. In detail, a method for managing a device to device (D2D) terminal group in a wireless communication system may include the steps of: receiving, by a first terminal which belongs to the D2D terminal group, a discovery signal from a second terminal which belongs to the D2D terminal group on a physical sidelink discovery channel (PSDCH); calculating, by the first terminal, a position of the second terminal by using the discovery signal; and displaying, by the first terminal, the position of the second terminal based on the position of the first terminal.

Abstract: The present invention discloses a proximity based notification method in a wireless communication system and a device for the same. In detail, a proximity based notification method in a wireless communication system supporting device to device communication (D2D) may include the steps of: configuring, by a first terminal, a list of terminals which participate in an notification service and a notification time; broadcasting, by the first terminal, a discovery signal including a first D2D ID on a physical sidelink discovery channel (PSDCH) when the notification time arrives; and outputting, by the first terminal, a notification for notifying that a second terminal is proximate when the first terminal receives a second discovery signal including a second D2D ID from the second terminal included in the terminal list on the PSDCH.
