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.

Abstract: The present subject matter relates to a method including receiving a set of signals from transmitters of a communication system, the communication system having a system configuration. A first and second set of machine learned parameters may be provided in accordance with the system configuration. The received signals may be weighted using the first set of machine learned parameters. The weighted signals may be combined to generate a composite signal. The composite signal may be weighted with the second set of machine learned parameters in order to estimate an interference signal that is caused by the set of signals at a receiver of the communication system.

Abstract: A method including capturing a signaling on a transmission path conveying a signal to be transmitted and on a reception path conveying a signal being received, setting model parameters related to a distortion effect on the basis of the captured signaling, the distortion effect being caused by the signal to be transmitted on the signal being received due to passive intermodulation between the transmission path and the reception path, generating a reference signal being related to a predetermined frequency spectrum part used by the signal being received by applying the model parameters on a captured signaling on the transmission path, and correcting the signal being received by using the generated reference signal.
