Abstract: The present invention relates to a method and an apparatus for transmitting control information for device-to-device (D2D) communication. A method for communicating between terminals of a transmission terminal according to an embodiment of the present invention comprises the steps of: determining whether transmission data corresponds to final transmission data; generating a first channel sensing signal including information indicating that the transmission data corresponds to final transmission when the transmission data is final transmission data; and transmitting the transmission data and the first channel sensing signal. According to an embodiment of the present invention, a channel sensing signal, which is necessarily required for a D2D operation of a distributed resource allocation scheme, is used to transmit the control information so that control information can be exchanged between terminals without introducing an additional control channel and signal.
