  • performing a round trip time (RTT) measurement to obtain an RTT between the BS and the UE;

    receiving beam information and the RTT in a Node B Application Part (NBAP) message, the beam information indicating a selection of a beam, from the two or more beams, to serve the UE; and

    positioning the UE by determining an area where the UE is located in the cell based at least in part on both the beam information and the RTT included in the NBAP message, wherein positioning the UE in the cell based on the obtained RTT and the determined area comprises using a Polygon to Ellipse Transformation Algorithm.
