摘要： 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.

摘要： In some embodiments, a terminal-to-terminal network may include one or more terminals each configured to receive a timing reference signal. The one or more terminals may be further configured to select a timing offset relative to a periodic transmission frame of the terminal-to-terminal network. The timing offset may be associated with a time relative to the periodic transmission frame at which a timing synchronization signal is broadcast. The timing synchronization signal may be based at least in part on the timing reference signal. The one or more terminals may be further configured to select a timing synchronization signal transmission rate. The one or more terminals may be further configured to broadcast the timing synchronization signal at the timing offset and at the timing synchronization signal transmission rate.

摘要： A communication system that can improve the efficiency with which a Control Channel (CCH) is used in a resource. The communication system includes a base station (10), a terminal B that is inside an arrival coverage of a physical control format indicator channel (PCFICH) signal containing a control format indicator (CFI), and a terminal A that is outside the arrival coverage. The base station (10) updates the CFI during a time period of 1 ms and updates the physical hybrid ARQ indicator channel (PHICH) duration during a time period of 40 ms. The base station (10) performs scheduling of the data to be sent to the terminal B for each subframe, whereas the base station (10) performs scheduling of the data to be sent to the terminal A only in a subframe in which the PHICH duration value matches the CFI value. The terminal A acquires data to be sent to the terminal A on the basis of the CCH region size determined in accordance with the PHICH duration value transmitted from the base station (10).
