Claim Text:
1. A method of determining position information, wherein the method comprises: receiving, by an evolved Node B (eNB), an uplink signal from a User Equipment (UE); determining, by the eNB, an angle of arrival, a downtilt angle of beam and a timing advance of the UE from the received uplink signal; and positioning, by the eNB, the UE using the angle of arrival, downtilt angle of beam and timing advance of the UE; wherein the eNB positions the UE using the equations of: wherein x_UE represents the coordinate of the UE on the x-axis; y_UE represents the coordinate of the UE on the y-axis; z_UE represents the coordinate of the UE on the z-axis; x_eNB represents the coordinate of the eNB on the x-axis; y_eNB represents the coordinate of the eNB on the y-axis; z_eNB represents the coordinate of the eNB on the z-axis; m represents the ratio of the distance between the UE and the eNB to the distance determined from the TA, and n represents the distance over which light propagates in a unit of time the TA represents the Timing Advance; the AoA represents the angle of arrival; and the AoA′ represents the downtilt angle of beam.
