  • Patent number: 11553391
    Abstract: In a wireless User Equipment (UE), a serving radio wirelessly exchanges data with a serving cell over a serving radio band. The wireless UE wirelessly receives serving signaling that indicates serving uplink interference for the serving radio band at the serving cell. A neighbor radio in the UE wirelessly receives neighbor signaling. UE circuitry determines serving signal strength and the serving uplink interference for the serving cell. The UE circuitry determines neighbor signal strength for the neighbor cell. The UE circuitry compares the serving uplink interference and the serving signal strength to the neighbor signal strength, and in response, generates a handover request for the neighbor cell. The serving radio wirelessly transfers the handover request to the serving cell, and in response, the neighbor radio wirelessly exchanges additional data with the neighbor cell over the neighbor radio band.

  • Patent number: 11343681
    Abstract: Methods and systems are provided for dynamically adjusting the beamform of an antenna array. An intended beamform, which should ideally be propagated by an antenna array based on a supply of a first set of signals, may not be realized if one or more antenna elements of the antenna array are experiencing a fault. Utilizing various methods, one or more faulty antenna elements of the antenna array are identified and a second set of signals is calculated that, when propagated by one or more operational antenna elements, yield an optimized beamform, wherein the optimized beamform at least partially recovers a portion of a coverage gap.
