Abstract: Provided is a radio resource management method for device-to-device communication. The resource management method for device-to-device communication includes dividing a plurality of connection identifiers (CIDs) into N (N is a natural number) number of groups, dividing the resources for device-to-device communication into N number of sub-bands corresponding to the N number of groups, and allocating resources by mapping CIDs respectively belonging to the N number of groups to resources of sub-bands respectively corresponding to the groups. Therefore, according to the resource management method, by dividing the whole frequency band into a plurality of sub-bands, a communication range may be extended, a low-power device may be accommodated, granularity of resources may be improved, and flexibility of resource management may be obtained.

Abstract: A method for discovery using a device-to-device link is disclosed. A method of operating a device includes receiving a request to transmit discovery information, and transmitting or not transmitting the discovery information based on the request. Using the method of operating a device, power consumption of devices and waste of radio resources in a discovery process of direct communication between devices can be reduced, and a problem of resource collision between adjacent devices can be resolved. Further, a problem of adjacent devices assigned to specific frequency resources having a bad channel property not being discovered can be resolved by coping with frequency selectivity.

Abstract: Disclosed is a device to device (D2D) communication method. The D2D communication method includes generating a connection identification (CID) for D2D communication using an identification (ID) of a specific terminal, selecting a sequence corresponding to the CID, and transmitting the selected sequence using a paging request resource including a plurality of subcarriers. Accordingly, even in a channel selective wireless environment, a performance of a wireless link may be improved, and usage efficiency of wireless resources may be improved.
