  • Feedback Based on Codebook Subset
    Publication number: 20200091973
    Abstract: The present invention provides for an improved application of signal strength weightings in a SDMA sectorized cellular network. The improved signal strength weightings application is conducted through the improved selection of weightings from a new codebook subset or by the selection of weightings from a larger codebook subset. In a further embodiment, an antenna beam index or bit map can be used to select the best beam(s) in a SDMA sectorized cellular network. In another embodiment, a field or factor in an uplink or downlink transmission packet can designate which directional transmission beam is best suited for the transmission or when the directional transmission beam should be activated.

  • Providing a downlink control structure in a first carrier to indicate information in a second different carrier
    Patent number: 10548135
    Abstract: A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specitl.es resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.

  • User equipment battery saving in a HetNet deployment with eICIC
    Patent number: 10506512
    Abstract: Devices and methods are provided for reducing client node power consumption when monitoring first and second channels corresponding to first and second access nodes in a heterogeneous wireless-enabled communications environment. Enhanced Inter-Cell Interference Coordination (eICIC) operations are performed to mitigate interference between a first access node and a second access node. The client node monitors first and second channels corresponding to the first and second access nodes to detect the presence of Almost Blank Subframes (ABS) pattern data transmitted on the first channel. When detected, the client node ceases monitoring the first channel to reduce power consumption and thereby conserve battery resources.

  • DUAL WIDTH FINNED SEMICONDUCTOR STRUCTURE
    Publication number: 20190371678
    Abstract: A finned semiconductor structure including sets of relatively wide and relatively narrow fins is obtained by employing hard masks having different quality. A relatively porous hard mask is formed over a first region of a semiconductor substrate and a relatively dense hard mask is formed over a second region of the substrate. Patterning of the different hard masks using a sidewall image transfer process causes greater lateral etching of the relatively porous hard mask than the relatively dense hard mask. A subsequent reactive ion etch to form semiconductor fins causes relatively narrow fins to be formed beneath the relatively porous hard mask and relatively wide fins to be formed beneath the relatively dense hard mask.
