  • Patent number: 8914054
    Abstract: Systems and methods are disclosed for selecting resources for direct device to device communications in a cellular communication network. Preferably, resources for the direct device to device communications are selected to minimize, or at least substantially reduce, interference that results from the direct device to device communications in the cellular communication network. In one embodiment, a downlink resource of the cellular communication network is selected as a resource for a direct device to device communication link between a first wireless device and a second wireless device if at least one of the first and second wireless devices is less than a predefined threshold radio distance from a closest base station in the cellular communication network. Otherwise, an uplink resource of the cellular communication network is selected as a resource for the direct device to device communication link between the first and second wireless devices.

  • Patent number: 8913530
    Abstract: Systems and methods are disclosed for selecting resources for direct device to device (D2D) communications in a cellular communication network. Preferably, resources for the direct D2D communications are selected to minimize, or at least substantially reduce, interference that results from the direct D2D communications in the cellular communication network. In general, either an uplink resource or a downlink resource of the cellular communication network is selected for a direct D2D communication link between a first wireless device and a second wireless device in order to minimize, or at least substantially reduce, interference caused to a third wireless device that uses the same uplink and downlink resources in the same and/or a neighboring cell of the cellular communication network.
