  • Publication number: 20240089748
    Abstract: The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal.

  • Patent number: 11927549
    Abstract: The present disclosure provides an inspection system and a method of stray field mitigation. The system includes an array of electron beam columns, a first permanent magnet array, and a plurality of shielding plates. The array of electron beam columns each includes an electron source configured to emit electrons toward a stage. The first permanent magnet array is configured to condense the electrons from each electron source into an array of electron beams. The first permanent magnet array is arranged at a first end of the array of electron beam columns. The plurality of shielding plates extend across the array electron beam columns downstream of the first permanent magnet array in a direction of electron emission. The array of electron beams pass through a plurality of apertures in each of the plurality of shielding plates, which reduces stray magnetic field in a radial direction of the array of electron beams.

  • Patent number: 11923939
    Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.
