    Abstract: The present invention relates to a method and a device for reducing the power of a device in a wireless communication system supporting direct device to device (D2D) communication. A method, for transmitting a signal of a device in a wireless communication system supporting direct D2D communication according to the present invention, comprises the steps of: entering sleep mode in direct D2D communication between a device and an opponent device; if data to be transmitted to the opponent device is generated, transmitting a paging signal for the opponent device to a base station connected to the device, thereby requesting transmission of the paging signal to the opponent device; and resuming the D2D communication with the opponent device that has received the paging signal through the base station.

    Abstract: A method and an apparatus for concealing an error of an apparatus for receiving an audio frame in a communication system are provided. The includes determining whether the error occurs in a current audio frame that is received from a transmitter, determining whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs, setting a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal, and concealing the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.
