  • Patent number: 11146328
    Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.

  • Patent number: 10674454
    Abstract: The disclosure provides for a compressed mode transmission gap in wireless communications. A user equipment (UE) may receiving a downlink dedicated physical channel (DPCH) having a slot-format and a spreading factor during a first compression interval. The downlink DPCH may not include a compressed-mode transmission gap during the first compression interval. The UE may receive the downlink DPCH having the same slot-format and the same spreading factor during a second compression interval. The UE may determine that the downlink DPCH includes a compressed-mode transmission gap during the second compression interval. A set of slots of the downlink DPCH during the transmission gap may be punctured. The UE may decode the downlink DPCH for the second compression interval based on a set of remaining slots received during the second compression interval. In an aspect, the UE may estimate a SIR based on a TPC command in a last slot of the transmission gap.
