Angle of arrival (AOA) positioning method and system for positional finding and tracking objects using reduced attenuation RF technology

A method for determining an elevation of a user equipment (UE) in communication with a wireless system, the method comprising:

• buffering a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with at least two antennas or four or more omnidirectional antennas;
• identifying the signals from each receive channel among the receive channels as previously known signals based on the buffered I/Q samples;
• based on the previously known signals from each receive channel determining an angle of arrival from the UE to the at least two antennas or the four or more omnidirectional antennas, wherein determining the angle of arrival includes determining a sub-sample estimation of at least one of a direct line of sight (DLOS) flight time and a direct path flight time from the UE to each antenna among the at least two antennas or the four or more omnidirectional antennas, wherein the sub-sample estimation mitigates a mirror image of a true line of bearing (LOB) between the UI and the at least two antennas or the four or more omnidirectional antennas;
• and
• utilizing the angle of arrival to calculate the elevation of the UE.
