A user equipment (UE) receives a plurality of positioning reference signals (PRSs) from a plurality of base stations. The plurality of base stations includes a serving base station and two neighboring base stations. The UE estimates a plurality of line-of-sight (LOS) paths and corresponding indexes of the PRSs for time of arrival (TOA) and time difference of arrival (TDOA) measurements. The UE then estimates an elevation angle of the UE based on the estimated LOS paths of the PRS from the serving base station. Finally, the system (either UE or network, depending on where the coordinates are) can calculate the UE position based on the TDOA measurements and the elevation angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Localization-based beamforming scheme for systems with multiple antennas","description":"A method of accurate 3D positioning with reduced cost is proposed.
