D2DDEVICE-TO-DEVICE D2D D2D METHOD FOR ALLOWING BASE STATION TO SUPPORT DEVICE-TO-DEVICE D2D COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM AND METHOD FOR ALLOWING D2D DEVICE TO EFFICIENTLY TRANSMIT D2D COMMUNICATION REQUEST SIGNAL
A method for a base station supporting device-to-device (D2D) communication according to the present invention includes: receiving a first signal requesting D2D communication from a first plurality of D2D terminals; Determining a number of D2D terminals requesting the D2D communication based on the first signal, transmitting a second signal requesting D2D communication between the D2D terminals based on the number of the first plurality of D2D terminals detected Allocating resources; And transmitting information on the allocated resources to the first plurality of D2D terminals that transmitted the first signal, wherein the resource allocation is performed by the first plurality of D2D terminals Frequency, code, and spatial domain with respect to the combination of the index of the D2D terminal for transmitting the second signal and the index of the D2D terminal for receiving the second signal.
