Method and device for determining the bearing of an incoming radio signal in a mobile communications network

摘要

The reception levels of the downlink radio signals transmitted by the antennas, are measured by the mobile communication terminal (MS). A ratio value is estimated between the reception levels, to estimate azimuthal angles for determining the radio reception direction (D). Independent claims are also included for the following: (1) mobile communication network; (2) computer; (3) radio base station; and (4) mobile communication terminal.
