1. A method for supporting positioning of a mobile device in a wireless network performed by a location server, the method comprising:
obtaining an array gain distribution variation as a function of angle and frequency for a set of beam weights used in beamforming by at least one base station;
receiving at least one angle based positioning measurement for the mobile device from at least one network node; and
determining a position estimate of the mobile device based on the at least one angle based positioning measurement and the array gain distribution variation as the function of angle and frequency for the set of beam weights used by the at least one base station.
