Patent number: 11876588Abstract: Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.Type: GrantFiled: May 16, 2022Date of Patent: January 16, 2024Assignee: Futurewei Technologies, Inc.Inventors: Pengfei Xia, Bin Liu
