The angle based positioning measurements are generated using transmit (Tx) beams or receive (Rx) beams from one or more base stations that generate the beams over an ultra-wide bandwidth, which produces frequency and spatial distortions and impairments in an array gain response. The array gain distribution variation as a function of angle and frequency for the set of beam weights used in beamforming is conveyed to indicate the frequency and spatial distortions. The array gain distribution variation may be provided to the mobile device in assistance data for a sub-band that is only a portion of the allocated bandwidth for the base stations, or as an aggregation of the array gain distribution variation for a plurality of sub-bands of the allocated bandwidth to reduce the overhead in signaling."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for low overhead frequency-averaged beam pattern feedback in millimeter wave positioning systems","description":"The position of a mobile device is estimated using angle based positioning measurements.
