  • Patent number: 9918349
    Abstract: A proxy node includes reception logic operable to receive data from a first node for transmission to a second node over a communications link; determination logic operable to determine a selected proxy node from a group of proxy nodes, the selected proxy node being one of the group of proxy nodes where a difference in a communications link characteristic of a communications link between the proxy node, the selected proxy node and the second node and a communications link characteristic of a communications link between the proxy node and the second node falls within a threshold amount; and transmission logic operable to establish a rateless coded communications link for transfer of the data with the selected proxy node.

  • Patent number: 9451623
    Abstract: A method is provided in a small cell base station comprising multiple antennas of controlling reception pattern by selecting a subset of the antennas for use. The method comprises determining a ranking value for each of subsets of the antennas dependent upon measurements of received signal quality, and choosing the subset of the antennas for use that provides the highest ranking value.

  • Publication number: 20160218825
    Abstract: A rateless decoder method includes receiving a plurality of ratelessly encoded data symbols from a rateless encoder; identifying a decoding symbol from the plurality of ratelessly encoded data symbols, the decoding symbol comprising at least a second degree ratelessly encoded data symbol; locating a higher degree symbol from the plurality of ratelessly encoded data symbols, the higher degree symbol comprising at least a third degree ratelessly encoded data symbol; determining whether the higher degree symbol encodes the decoding symbol and, if so, decoding the higher degree symbol to remove the decoding symbol and provide a degree-reduced symbol.

  • Patent number: 9319995
    Abstract: The present invention relates to a method and an apparatus for controlling the transmit power of a mobile station (UEX) served by a small cell (C1). In accordance with an embodiment of the invention, the method comprises the steps of, and the apparatus comprises means for, detecting a measurement event anticipating the forthcoming fulfillment of a handover condition towards a neighboring macro cell (C2) by the mobile station, and thereupon step-wise increasing the transmit power level of the mobile station so as to reach a transmit power target (P_Target) when the handover condition is eventually fulfilled by the mobile station. The transmit power target is for compensating for an estimated downlink path loss for the mobile station in the macro cell.

  • Publication number: 20110219443
    Abstract: The invention is directed to an inter-host signaling protocol, referred to herein as Knock-On Protocol (KOP), for establishing in a secure manner a connection with a host behind firewall. Some embodiments of the invention are directed to a Knock-On Feature (KOF) used in intermediate firewalls or network address translators to enable connection establishment through the FW or NAT to hosts behind the FW or NAT. Advantageously the KOF may include a prefix-based protection feature to protect against address spoofing used in a message flood attack.
