Abstract
Systems and methods for angle of arrival determination in wireless devices include one or more processors which determine a first angle of arrival (AoA) and a first distance between a user device and an anchor device at a first time instance, according to first measurements between a single ultra-wideband (UWB) antenna of the user device and a plurality of UWB antennas of the anchor device. The processor(s) may determine a second AoA and a second distance between the user device and the anchor device at a second time instance, according to second measurements between the single UWB antenna of the user device and the plurality of UWB antennas of the anchor device. The processor(s) may determine a direction of movement of the user device relative to the anchor device, according to the first AoA, the first distance, the second AoA, and the second distance.
