1. A method for determining an orientation of a user equipment, comprising:
determining a first location associated with the user equipment;
determining a second location associated with a first wireless node;
receiving, with the user equipment, a radio frequency signal transmitted from the first wireless node;
determining two measurements based at least in part on the first location, the second location, and angle of arrival information associated with the radio frequency signal;
determining a gravity vector based on inertial measurements obtained with the user equipment; and
computing the orientation of the user equipment based at least in part on the gravity vector and the two measurements.
