Abstract
Embodiments are presented herein of apparatuses, systems, and methods for a wireless device to calibrate a phased antenna array. The wireless device may begin a calibration process with a second wireless device. The first wireless device may receive a calibration signal from the second wireless device and may calibrate a subset (e.g., all but one) of the antennas of the array. The first wireless device may receive a subsequent signal and estimate the angle of arrival using the calibrated subset of antennas. Further, the first wireless device may calibrate a complete set of antennas using calibration signals from a plurality of directions.
