Abstract: Disclosed is a method comprising selecting (401), by a base station, a power amplifier distortion model from a set of power amplifier distortion models, wherein the power amplifier distortion model comprises a pre-trained machine learning model configured to compensate power amplifier distortion. The method further comprises receiving (402), by the base station, one or more uplink data transmissions from a terminal device, and compensating (403), by the base station, at least a part of the power amplifier distortion from the one or more uplink data transmissions based at least partly on the power amplifier distortion model.

Abstract: This document discloses a solution for searching a downlink control channel by a terminal device. According to an aspect, a method performed by the terminal device comprises: determining at least a first search space configuration and a second search space configuration for searching for a downlink control channel from a received signal, wherein the first search space configuration defines first starting positions and first durations for a first set of periodic search windows and the second search space configuration defines second starting positions and second durations for a second set of periodic search windows different from the first set of periodic search windows: determining a first set of periodic search spans formed by a first subset of time-domain symbols of each search window in the first set of periodic search windows and further determining a second set of periodic search spans formed by a second subset of time-domain symbols of each search window in the second set of periodic search windows: forming a sequence of search spans from the first set of periodic search spans and the second set of periodic search spans and determining a virtual search window changing in duration as dependent on a time interval between consecutive search spans in the sequence of search spans; determining, on the basis of a duration of the virtual search window, a maximum number of downlink control information candidates the terminal device is capable of processing within the virtual search window, wherein the maximum number of downlink control information candidates is configured to change together with the changing duration of the virtual search window; searching the received signal within the virtual search window for up to the maximum number of downlink control channel candidates and omitting the searching for remaining downlink control channel candidates and, upon detecting the downlink control channel, extracting downlink control information on the downlink control channel.
