    摘要： An apparatus and method of allowing user equipment to transmit information directly with other user equipment, using a device-to-device mode is disclosed herein. A device-to-device blank subregion is defined where device-to-device information can be transmitted without interference from other user equipment. The device-to-device blank subregion may be set up such that it is only used in an exclusive mode if a device-to-device cluster is considered highly interfering. A device may join a device-to-device network through the use of a beacon transmission interval, a control transmission interval, and a data transmission interval.

    摘要： A method to transmit and receive a device-to-device (D2D) discovery signal method is disclosed. The D2D discovery signal method operates using currently defined discovery signals as well as novel discovery signals, such as discovery signals employing a PUCCH-based uplink signal, an SRS-based demodulation and reference signal, or a single tone-based beacon signal. Under the D2D discovery signal method, an enhanced base station (eNB) configures the D2D discovery signal to both the transmitter (TX) user equipment (UE) and the receiver (RX) UE, then activates the D2D discovery signal to the TX and RX UEs, such that D2D signal transmission can thereafter occur from either the eNB or the TX UE, and monitored by the RX UE. Once the eNB deactivates the D2D discovery signal, D2D transmissions between UEs cease. Transmissions to configure, activate, and deactivate the D2D discovery signal can be unicast, multicast, or broadcast.

    摘要： Embodiments of wireless communication devices and methods for device discovery is generally described herein. Some of these embodiments describe an apparatus having processing circuitry arranged to configure a single-tone discovery signal for transmission in a symbol in a transmission opportunity based on an assignment pattern. The assignment pattern may define frequency positions, for a set of transmission opportunities, at which the apparatus shall transmit discovery signals in the corresponding transmission opportunity. The apparatus may have physical layer circuitry arranged to transmit the single-tone discovery signal in the corresponding transmission opportunity. Other methods and apparatuses are also described.
