Abstract:
1. A method for generating a Connection Identifier (CID) for Device-to-Device (D2D) communication, the method comprising: transmitting a request signal for requesting direct communication between a transmitting device and a receiving device on a resource unit of a first resource index determined based upon a device ID of the transmitting device and a device ID of the receiving device during a predetermined first period; receiving information about at least one used CID being used by at least one surrounding device from the at least one surrounding device during a second period following the first period; transmitting generation information including at least one available CID acquired during the second period to the receiving device, on a resource unit of a second resource index being identical to the first resource index during a third period following the second period; and determining at least one CID to be used for D2D communication between the transmitting device and the receiving device from the at least one available CID included in the transmitted generation information, wherein the first resource index is calculated by performing a predetermined operation on the device ID of the transmitting device and the device ID of the receiving device and performing a modulo operation on a result value of the predetermined operation.
