Determining an orientation of a user equipment with a cellular network

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;
• determining a third location associated with a second wireless node;
• determining a first angle of arrival information associated with a radio frequency signal transmitted from the first wireless node and received by the user equipment;
• determining a first two measurements based at least in part on the first location, the second location, and the first angle of arrival information;
• determining a second angle of arrival information associated with a radio frequency signal transmitted from the second wireless node and received by the user equipment;
• determining a second two measurements based at least in part on the first location, the third location, and the second angle of arrival information;
• and
• computing the orientation of the user equipment based at least in part on the first two measurements and the second two measurements.

An apparatus, comprising:

• a memory;
• an inertial measurement unit;
• at least one transceiver;
• at least one processor communicatively coupled to the memory, the inertial measurement unit, and the at least one transceiver, and configured to:
• determine a first location associated with the apparatus;
• determine a second location associated with a first wireless node;
• receive a radio frequency signal transmitted from the first wireless node;
• determine 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;
• determine a gravity vector based on inertial measurements obtained with the inertial measurement unit;
• and
• compute an orientation of the apparatus based at least in part on the gravity vector and the two measurements.
