Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may communicate via a serving beam set of the UE, the serving beam set being one or more of a plurality of beams. The UE may measure another beam set in accordance with a measurement schedule configured to prioritize measurement on one or more adjacent beam sets associated with the serving beam set over one or more non-adjacent beam sets associated with the serving beam set. In some aspects, the one or more adjacent beam sets may be associated with one or more coverage areas that at least partially overlap a coverage area of the serving beam set, are adjacent to the coverage area of the serving beam set, or are associated with a measurement value that satisfies a threshold in the coverage area of the serving beam set. Numerous other aspects are provided.

Abstract: Aspects described herein include devices and methods for facilitating digital predistortion calibration. One aspect includes selecting a first transmission element from a plurality of transmission elements associated with a first antenna element of a plurality of antenna elements in an antenna array of the millimeter wave communication device, wherein the first transmission element is selected based on a gain setting for the first transmission element, selecting a reference transmission power for a test transmission from the first transmission element as part of a path searching operation of the millimeter wave communication device, determining a selected receive element of the plurality of receive elements based on a near field power measurement of the reference transmission power from the first transmission element using the selected receive element and a set of selection criteria, and setting a digital predistortion calibration setting using the reference transmission power and the near field power measurement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication and testing. In some aspects, a device may receive information identifying a mount orientation of a wireless communication device, wherein the mount orientation indicates an orientation of a coordinate system of the wireless communication device relative to a coordinate system of a positioner. The device may capture measurement information at each position of a set of positions of the wireless communication device, wherein the set of positions comprises positions of the wireless communication device as the wireless communication device is rotated around an axis by the positioner, and wherein the measurement information is captured based at least in part on the mount orientation. The device may provide information identifying the measurement information. Some techniques and apparatuses described herein may use the measurement information to generate a codebook for beam generation. Numerous other aspects are provided.
