Original Abstract Submitted
Techniques are disclosed for enabling low-power positioning of a first mobile device using differential angle of arrival (AoA). A differential AoA between a first AoA of a first wireless reference signal at a second mobile device and a second AoA of a second wireless reference signal at the second mobile device is obtained, where the first wireless reference signal is transmitted by a wireless network node, and the second wireless reference signal is transmitted by the first mobile device. The position of the first mobile device is determined based at least in part on the differential AoA. The position of the first mobile device is then provided.
