  • WIRELESSLY TRANSMITTING MULTI-CAST SIGNAL USING RATELESS CODES
    Publication number: 20150358058
    Abstract: Data is transmitted over a wireless network by encoding data using a rateless code. A multi-cast signal is wirelessly transmitted to communicate the encoded data for any one or more receivers. The wireless transmission is performed in a manner that is agnostic as to a number of antennas that are utilized by each of the one or more receivers.

  • DEGREES OF FREEDOM IN MULTICELL WIRELESS SYSTEMS WITH FULL-DUPLEX BASE STATIONS USING INTERFERENCE ALIGNMENT AND METHODS FOR ENABLING FULL-DUPLEX WITH HALF DUPLEX CLIENTS
    Publication number: 20150223173
    Abstract: An interference alignment system for communication structures that includes a single cell channel comprising an access point node, and a full bipartite interference channel (FBIC) configuration of a plurality of receiving nodes and a plurality of transmitting nodes. Each receiving node sees an interfering signal from all transmitting nodes. The access point node of the single cell channel provides a single node having downlink channels to all receiving nodes in the FBIC, and all of the uplink channels from the FBIC are to the single access point node to the single cell channel.

  • Transmitting a wireless signal based on detected signal interference
    Patent number: 9001927
    Abstract: A computing device can determine a radio frequency (RF) bandwidth in which one or more frames are to be transmitted by the computing device. The RF bandwidth is within the operating transmission bandwidth of the computing device. A signal interference having an interference bandwidth can interfere with the transmission of the one or more frames. In response to detecting the signal interference, one or more frames can be transmitted within the operating transmission bandwidth and not within the interference bandwidth.
