Abstract
A wireless device is used in a wireless communication system that includes a base station for controlling communication in which a time division duplex frame including at least one uplink subframe and at least one downlink subframe is transmitted. The wireless device includes: a request transmitter that transmits a request for performing D2D (device-to-device) communication to the base station; a receiver that receives position information to indicate a position at which a blank subframe is allocated in the time division duplex frame from the base station; and a scheduler that determines a schedule for D2D communication based on the position information and reports the schedule to a corresponding wireless device. The blank subframe is configured to include a symbol for control signal and a plurality of blank symbols in which no signal is transmitted from the base station.
