Abstract
Mechanisms for passive intermodulation (PIM) avoidance. A method is performed by a controller. The method includes determining, based on presence of uplink PIM, to which fractions of transmission resources within a transmission slot a transmission power reduction factor is to be applied. The fraction of transmission resources is, in a logarithmic domain and according to a feedback control loop, determined as a function of a comparison between a measured improvement of the uplink PIM when having applied the transmission power reduction factor in a most recent transmission slot and a reference value for the improvement of the uplink PIM. The measured improvement of the uplink PIM is given by, in each transmission slot, probing a radio channel over which the uplink PIM is received. The method includes applying the transmission power reduction factor to the determined fraction of transmission resources within the transmission slot during transmission of a signal.
