Inhalt:
By increasing the deployment of beamforming capabilities in mobile communication networks the user direction becomes readily available at base stations (BSs). Utilizing the angles of arrival (AOAs) from multiple BSs enables the calculation of the user position within one additional step using triangulation techniques. In our work we state the mathematical problem and derive the associated Cramer-Rao lower bound (CRLB). Further on we compare a recently proposed linear LS estimator with a trivial triangulation technique and the corresponding CRLB in three simulation scenarios.
