    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: Disclosed is device-to-device communication based on a cellular communication network. A method of operating a terminal capable of supporting D2D (device to device) communication based on a cellular communication network may include: determining whether to perform central control D2D communication or distributed control D2D communication; and performing the distributed control D2D communication, or requesting a setting for the central control D2D communication to a base station on the basis of the determination. With the D2D communication based on the cellular communication network, the cellular communication, the central control D2D communication, or the distributed control D2D communication may flexibly and selectively operate in the cellular network.

    Abstract: Disclosed is a method for transmitting radio frequency signals. In the method according to the present invention, a plurality of antenna groups may be arranged for achieving array gain and multiplexing gain at the same time, and the plurality of antenna groups are located far from each other so that they have no correlation, and antennas of the same group are located adjacent to each other so that they have correlation. Accordingly, system capacity as well as capacity of data channel and control channel may be significantly increased through mitigation of inter-cell interference and enhancement of cell edge performance.

    Abstract: Disclosed is a method for configuring and transmitting control channel for radio communication. A method for configuring control channel comprises a step of configuring a control channel by using a plurality of tiles, wherein numbers of resource elements in the plurality of tiles are configured to be the same or different. If a method for transmitting control information comprising a small number of bits according to the present invention is used, quality of communication and efficiency of resource may be increased at the same time.
