    Abstract: Disclosed is a method and apparatus for scheduling in a cellular-based device-to-device (D2D) communication. The method of scheduling a cellular resource used in a base station for a D2D communication between terminals may include grouping, by a proximity coordinator, a cellular resource of an adjacent base station based on cell information of a base station, managing a resource to be allocated to the terminal and a resource allocated previously to the terminal based on the grouped resource, and allocating the grouped resource to the terminal based on information associated with the resource to be allocated and the previously allocated resource when a request for D2D communication between terminals located in different cells is received.

    Abstract: Disclosed is a proximity measurement method and apparatus for device-to-device (D2D) communication in a mobile communication system. The proximity measurement method may include determining whether a cell identification (ID) is included in a packet received from a gateway, verifying whether the cell ID matches a pre-stored cell ID when the cell ID is included, extracting, from the packet, Internet Protocol addresses of mobile terminals transmitting and receiving the packet when the cell ID matches the pre-stored cell ID, searching for IP addresses matched to the extracted IP addresses based on a proximity list including IP addresses of mobile terminals performing D2D communication, and registering, when the extracted IP addresses are absent in the proximity list, the extracted IP addresses in the proximity list and measuring proximity between the mobile terminals.

    Abstract: Disclosed is a discovery method and apparatus for device-to-device (D2D) communication in a cellular mobile communication system. The discovery method performed by the discovery apparatus may include obtaining, from a server managing information associated with terminals providing a service using a D2D communication scheme over a mobile communication network, information associated with a service provided by the terminals, selecting a service of interest based on the information associated with the service, receiving, from a base station, information associated with a discovery radio resource allocated to the terminals providing the service of interest, and discovering the terminals providing the service of interest based on the information associated with the discovery radio resource.

    Abstract: A method and an apparatus perform radio resource allocation. The radio resource allocation method includes receiving channel quality information from a UE, and allocating radio resources on the basis of the received channel quality information and a characteristic of at least one service to be provided to the UE. Accordingly, the radio resource allocation method can assure QoS, and enhance resource-use efficiency.
