  • Publication number: 20130059576
    Abstract: Apparatus and methods for synchronizing a network element (e.g. access points, femtocells, etc.) to a master network (such as a cellular network) to provide accurate frequency and/or time references for their internal systems. In one embodiment, the network element utilizes a dedicated receiver (or transceiver) to receive timing information from the master network. The implementation of the dedicated receiver is advantageous for cost and simplicity reasons. Furthermore, the timing or frequency information, as received from the master network, is used to correct the network element's internal timing. In addition, the network element's internal timing can operate in open-loop mode, if no master network can be found, thereby allowing for the device to continue providing service to network users. Additionally, a dedicated receiver can also receive information (e.g. location, SID, NID, SSID, etc.

  • Patent number: 8351379
    Abstract: In wireless system, a group of Base station (BTSs) with smaller footprints have the capability to communicate with each other as well as with the BTSs with relatively larger footprints via wireless air-interfaces. One of such example is coordinated cell systems. A coordinated cell system comprises a group of coordinated cell base stations that have the capability to communicate with each other as well as with relevant macro cell or Pico cell base stations via wireless air-interfaces. Each coordinated cell BTS consists of an over the air control unit in addition to the conventional coordinated cell BTS system.

  • Patent number: 8305199
    Abstract: A wireless remote control device for controlling an electronic device includes a switch module, a wireless transmission module, a wireless receiving module and a control module. The switch module receives a DC voltage and outputs a first control signal. The wireless transmission module receives the first control signal and encodes the first control signal to output an encoded first control signal. The wireless receiving module receives the encoded first control signal and decodes the encoded first control signal to output a decoded first control signal. The control module receives the decoded first control signal and outputs a second control signal to turn on/off or reset the electronic device.

  • Patent number: 8209575
    Abstract: A Hybrid Automatic Retransmission Request (H-ARQ) technique is provided for Multi-Input Multi-Output (MIMO) systems. The technique changes the basis (V) upon retransmission, which helps reduce the error probability upon retransmission. This basis hopping technique provides for improved performance gain without significant increase in design complexity. In one embodiment, communication device (100) includes a receiver section (114) for receiving an acknowledgment (ACK) or a non-acknowledgment (NACK) signal in response to information transmitted by the transmitter section of the communication device. If a NACK is received, a new basis is selected from a set of basis stored in a basis set unit (110). The new basis that is selected is then used by a linear transformation unit (106) in the retransmission of the information.

  • Patent number: 8149839
    Abstract: Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding network data traffic. In one embodiment, a network device uses a rotate function to generate a rotated index (path index) that is used to select a path (e.g., an ECMP) path from multiple paths (e.g., multiple ECMP paths) for forwarding a packet. A network device may also generate a rotated index (trunk index) that is used to select an output port from multiple output ports associated with a trunk for forwarding the packet.
