1. A method for determining a location of a user equipment (UE) in 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 two or more antennas;
receiving reference signal parameters that describe a reference signal within the signals;
identifying the reference signal within the signals from each receive channel among the receive channels;
based on the identified reference signal from each receive channel, determining an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas; and
utilizing the angle of arrival to calculate the location of the UE.
