Abstract

The present subject matter relates to an apparatus for a communication system. The apparatus is configured for: for each beam direction of a set of beam directions of an antenna array of the communication system, determining a level of a passive intermodulation, PIM, signal at a receiver of the communication system, the PIM signal being caused by a set of signals transmitted by the antenna array in the beam direction, identifying beam directions of the set of beam directions whose PIM level is higher than a predefined threshold, adapting a beamforming of signals in at least part of the identified beam directions to mitigate the PIM level at the receiver.
