    Abstract: A method and system for operator-assisted device-to-device (D2D) discovery is disclosed, which method may be executed as instructions on a machine, where the instructions are included on at least one computer readable medium. The method can include a transmission station in an operator network receiving a request for data service from a requesting wireless device. The transmission station can identify a serving wireless device to provide the data service for the requesting wireless device. The transmission station can transmit a device discovery message to the requesting wireless device and the serving wireless device. The device discovery message provides a device discovery period for communication via an ad-hoc, D2D network between the requesting wireless device and the serving wireless device. The ad-hoc, D2D network provides for device-to-device communication.

    Abstract: Described are techniques for managing the interference produced by D2D (device-to-device) transmissions that may be used in conjunction with transmit power control but operate independently. In one technique, interference between D2D transmissions and cellular uplink transmissions using common resources as received at a base station is managed by opportunistic interference alignment and clustering of D2D devices. In another technique, interference between different D2D devices using the same resources is mitigated by base-station aided space-time interference alignment.
