Provided are a method and apparatus for reporting power headroom in a wireless communications system supporting device-to-device (D2D) communications. According to the present invention, the method for reporting, by a terminal, the power headroom in the wireless communications system supporting the D2D communications, comprises the following steps: triggering a power headroom report when a triggering condition is satisfied; calculating power headroom in a sub-frame capable of transmitting the power headroom report to configure the power headroom report; and transmitting the power headroom report to a device which allocates a resource for the D2D communications. The triggering condition can be determined with respect to which D2D transmission is activated or not, or a D2D resource pool. |
