First Claim
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.

Abstract
Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, 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 is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.
