US 12,771,439 B2 · Beamforming muting

Abstract

The technology disclosed herein relates to beamforming muting. In embodiments, methods, systems, and computer storage media can transmit, via at least one antenna array using a listening mode for interference detection, a plurality of signals along a plurality of vectors of a coverage area. For example, the plurality of signals may be transmitted via an azimuth sweep from −90 to +90 degrees. Based on transmitting the plurality of signals, an interference above a predetermined threshold can be detected, the interference corresponding to a satellite earth station. Based on the interference, at least one beam of the antenna array can be identified for muting (e.g., based on a determined angle of arrival associated with the interference, based on the plurality of vectors used for the interference detection, based on an azimuth corresponding to the interference, etc.).
