Patent ID: 10855344

Abstract:
Systems and methods are provided for reducing massive multiple-input multiple-output (mMIMO)/5G out-of-band-emission. After detecting interference with an adjacent band, the mMIMO unit (MMU) determines the best corrective action based on calculations to determine if the equivalent isotropically radiated power would still lead to emissions in the adjacent band and, if required, apply one or more corrective actions. In one corrective action, the MMU reduces the overall power by turning off certain power amplifiers driving the dipoles. In another corrective action, the MMU changes the antenna beam width automatically to sway away from the target. In yet another corrective action, the MMU alternates the output power control range. In each of the aspects, the analysis is based on distance and boresight azimuth, as well as location factors. In some aspects, a topographic map of the affected area is utilized to determine clutter so that the selected corrective action is most effective.
