Apparatus and method for low overhead frequency-averaged beam pattern feedback in millimeter wave positioning systems

A mobile device configured for supporting positioning of the mobile device in a wireless network, comprising:

• a wireless transceiver configured to wirelessly communicate in the wireless network;
• at least one memory;
• at least one processor coupled to the wireless transceiver and the at least one memory, wherein the at least one processor is configured to:
• receive, via the wireless transceiver, assistance data for positioning, the assistance data comprising 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;
• measure at least one angle based positioning measurement of reference signals received from the at least one base station based on the assistance data;
• and
• generate position information based on the at least one angle based positioning measurement.
