  • Patent number: 9629153
    Abstract: Methods, systems, and apparatuses are described for adaptive dwell time for scan procedures. An access terminal (AT) may identify a scan period associated with performing a scan procedure on a first channel. The AT may analyze a channel congestion metric during the scan period and determine based, at least in part, on the channel congestion metric whether to exit the first channel. The AT may provide a probe request for transmission on a second channel during a remaining portion of the scan period based on the determination to exit the first channel.

  • Publication number: 20120276716
    Abstract: A process for wafer-to-wafer bonding of a first wafer having a first set of dies of a first die size to a reconstituted wafer of a second set of dies having a second die size different than the first die size. The process includes aligning the second set of dies such that a second set of interconnects on the second set of dies aligns with a first set of interconnects on the first set of dies. The second set of dies includes a spacing between the second set of dies based on parameters of the first set of dies. The process also includes coupling the reconstituted wafer with the first wafer to create a wafer stack.

  • Publication number: 20120002586
    Abstract: A wireless repeater includes a receiver circuit implemented as an intermediate frequency (IF) subsampling receiver and a transmitter circuit implemented as a direct conversion (zero-IF) transmitter. The repeater further includes a reference receiver implemented as an IF subsampling receiver to sample a portion of the transmit signal prior to over-the-air transmission for use as the reference signal for channel estimation. Highly accurate channel estimation is obtained by using the reference signal from the reference receiver as the reference signal accounts for distortions in the transmitter circuit of the repeater. The repeater may include an echo canceller to cancel an estimated feedback amount from an input signal based on the channel estimation.
