  • Patent number: 9363116
    Abstract: Embodiments provide an area, cost, and power efficient multi-service transceiver architecture. The multi-service transceiver architecture simplifies receiver/transmitter front ends needed for a multi-service architecture, by replacing significant portions of multiple receiver and/or transmitter front ends with a single ADC and/or DAC, respectively. In embodiments, a plurality of received service contents are combined into one composite analog/RF signal and applied to an ADC. The ADC converts the composite signal into a composite multi-service digital signal. Digital techniques are then used to separate the plurality of service contents into a plurality of respective digital streams that each can be independently demodulated. Similarly, in the transmit direction, a plurality of digital streams, including a plurality of service contents, are combined into one composite digital signal.

  • Patent number: 9363044
    Abstract: An arrangement is described for adapting outer loop precoder phase combiner in a radio communication system having coordinated multipoint transmission. In the arrangement ACK/NACK-message received as a response to a transmitted data packet is used for adapting the phase. When a NACK-message is received the phase may be adapted or it may be further determined if the error was due to error in channel code or due to destructive inter-point signal combining. If the error was due to destructive combining the phase is adjusted.

  • Publication number: 20160157233
    Abstract: A network access node identifies a component carrier within an unlicensed radio spectrum, determines whether or not to configure the component carrier for use as a secondary component carrier, and based on the determining configures the component carrier for use as a secondary component carrier companion to a primary component carrier within a licensed radio spectrum. In various non-limiting embodiments the network node senses the component carrier within the unlicensed radio spectrum, and as more data is needed to make the determination employs a mobile device to also sense and further to measure the component carrier within the unlicensed radio spectrum. Specific procedures are detailed for both the network node and the mobile device.

  • Patent number: 9356799
    Abstract: A network device located in an Ethernet ring may be operable to determine binding between a MAC address and a peer device in the Ethernet ring. The binding may indicate that the MAC address is behind the peer device. When an Ethernet ring failure occurs, the network device may be operable to update forwarding information based on a ring topology of the Ethernet ring, a position of the failure on the Ethernet ring and the binding. The forwarding information may indicate which ring port that is used on the network device to forward MAC frames to a destination corresponding to the MAC address. The network device may then forward the MAC frames based on the updated forwarding information. The Ethernet ring may utilize a VLAN frame format, a Q-in-Q frame format or a MAC-in-MAC frame format. The forwarding information may comprise a MAC table and/or a protection table.

  • Patent number: 9356664
    Abstract: Explicit feedback format within single user, multiple user, multiple access, and/or MIMO wireless communications. A beamformer provides a first communication to a beamformee, and based thereon, the beamformee may ascertain certain characteristics associated with the type and format of feedback to be provided to the beamformee via a second communication from the beamformee to the beamformer. For example, the first communication may include indication of a current operational mode, such as whether it is in accordance with single-user multiple input multiple output (SU-MIMO) or multi-user multiple-input-multiple-output (MU-MIMO). Also, the first communication may indicate a requested steering matrix's rank to be employed in accordance with subsequent beamforming by the beamformer. Also, additional information such as that pertaining to per-tone SNR values for each respective space-time stream, per-tone or per-sub-band eigen-values, the particular channel width being employed (e.g., 20, 40, 80, or 160 MHz), etc.

  • Patent number: 9357080
    Abstract: A system performs residual echo suppression on a microphone signal that receives, e.g., voice commands, and that is exposed to echo from multiple speakers. An example is a smartphone that receives voice commands while the smartphone is playing music through stereo speakers. The system estimates residual echo level in different ways, and determines which estimate to use. The technique responds well to the difficult to handle scenario of a spatially quiescent image suddenly transitioning to a spatially rich image. Even in the face of such difficult scenarios, the system detects and removes residual echo from the microphone signal, instead of allowing the undesired residual echo to pass through.

  • Patent number: 9356699
    Abstract: A dynamic readjustment of an energy efficient network control policy parameters in an optical network unit based on a Service Interoperability in Ethernet Passive Optical Network (SIEPON) protocol. The access link between the OLT and ONU has distinct properties that can be used to enhance the energy efficiency control policy on the network facing side of the ONU. In one embodiment, an adjustment mechanism can be based on the receipt, by an optical interface in an ONU, of a control command from an upstream OLT, wherein the control command is configured to provide a limitation on an available time period during which the ONU can communicate with the OLT over an optical fiber cable.
