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:

x_UE=x_eNB+m*TA*n*sin(AoA?)*sin(AoA);

y_UE=y_eNB+m*TA*n*sin(AoA?)*cos(AoA); and

z_UE=z_eNB?m*TA*n*cos(AoA?);

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.

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.
