Avoiding or correcting inter-cell interference based on an azimuthal modification
Methods and systems are provided for dynamically adjusting beamforming weights based on an azimuthal change request. A proposed azimuth change of an antenna is received, such as at a base station, where the proposed azimuth change is for remote azimuth steering of the antenna. A potential inter-cell interference is determined based on the proposed azimuth change. Based on the potential inter-cell interference, it can be predicted whether the proposed azimuth change can be made. The response, as to whether or not the proposed azimuth change can be made or not, is communicated to the base station.
