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
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
Method for supporting device-to-device (D2D) communication by a base station includes: receiving first signals for requesting D2D communication from a plurality of first D2D devices; identifying number of D2D devices which have requested the D2D communication based upon the first signals; allocating resources for transmitting a second signal for requesting D2D communication between the D2D devices based upon number of the plurality of first D2D devices which have been identified; and transmitting information on the allocated resources to the plurality of first D2D devices, wherein the resource allocation can be performed to distinguish combinations of an index of a D2D device, which transmits the second signal, and an index of a D2D device, which receives the second signal, from each other with respect to at least one of time, frequency, code, and space domains with respect to the plurality of first D2D devices.
