  • Patent number: 9374721
    Abstract: Methods and systems for reducing interference between base stations are disclosed herein. In accordance with an example method, a first base station iterates through emitting of a plurality of different radiation patterns from the first base station. The first base station also receives, from a second base station, feedback based on evaluation by the second base station of noise floor respectively for each of the different radiation patterns emitted from the first base station. Based on the received feedback, the first base station then sets itself to operate with a particular one of the radiation patterns. Example base stations and communication networks operable to perform the disclosed methods are also disclosed.
