Application: Method and system for downlink out-of-band interference mitigation (Patent ID: US20240106523A1)

The patent filed by Telefonaktiebolaget LM Ericsson discloses a method, system, and apparatus for downlink out-of-band interference mitigation. The method involves performing out-of-band null steering and in-band null steering towards a specific direction using a constant amplitude precoder to align radiation patterns associated with the out-of-band and in-band null steering. The system aims to maintain desired nulls while providing constant amplitude power for both out-of-band and in-band signals.

The claims of the patent detail the specific steps and configurations involved in implementing the method in a network node. This includes determining the constant amplitude precoder, utilizing normalization matrices, and achieving equal average power levels among all antenna branches. The network node is designed to perform null steering towards satellite ground stations, with in-band frequencies in the C-band range. The method also involves utilizing a look-up table for precoders and matrices, ensuring precise alignment of radiation patterns for effective interference mitigation in the specified frequency ranges.
