1. A method, comprising:
receiving, by a first device having at least one ultra-wideband (UWB) device, from a second device having a plurality of UWB devices, a report including a plurality of values comprising an elevation component of an angle of approach (AoA) from the first device and an azimuth component of the AoA from the first device, at least some of the plurality of values obtained according to measurements between the plurality of UWB devices of the second devices and the at least one UWB device of the first device; and
determining, by the first device, an AoA from the second device, using the plurality of values from the report received from the second device.
