Abstract: The present invention relates to a wireless power transmitting device. The wireless power transmitting device comprises a transmitter coil section with a plurality of partially overlapping transmitter coils; a fan for cooling heat generated by the transmitter coil section; and a controller for sending out a detection signal through the transmitter coil section, calculating the number of operating coils based on the strength of a response signal to the detection signal, and controlling the fan based on the calculated number of operating coils. Accordingly, heat generated by the transmitter coils can be reduced more efficiently.

Abstract: The present invention relates to a method and a device for transmitting, by a first terminal, a device-to-device (D2D) signal in a wireless communication system. Particularly, the method comprises the steps of: performing D2D transmission scheduling for a device-to-device synchronization signal (D2DSS) and a device-to-device channel (D2DCH); and transmitting a D2D signal on a first D2D subframe among a plurality of D2D subframes, wherein the first D2D subframe is a D2D subframe in which a D2D synchronization signal transmission for the first terminal is configured among D2D subframes configured to enable a D2D synchronization signal transmission, and the D2D signal drops the D2DCH when the D2DSS and the D2DCH are simultaneously scheduled on the first D2D subframe.
