The present disclosure relates to a method for transmitting and receiving a device-to-device (D2D) signal in a wireless communication system supporting D2D communication, said method, performed by a terminal, comprising the steps of: transmitting a cellular signal on a first subframe of a first component carrier; transmitting a D2D signal on a second subframe of a second component carrier; and when overlapping occurs between the first subframe and the second subframe, dropping the transmission of the D2D signal or reducing transmit power of the D2D signal in a specific interval.
