1. A method for determining a position 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 a plurality of antennas in at least one antenna enclosure, wherein each antenna among the plurality of antennas is displaced in one or more of a vertical direction and a horizontal direction with respect to other antennas among the plurality of 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 between a baseline of the plurality of antennas and incident energy from the UE to the plurality of antennas; and

    utilizing the angle of arrival to calculate the position of the UE.
