1. A method for determining a preferred downlink beam of a plurality of downlink beams; the method being performed in a wireless communication device configured to communicate with a network node of a cellular communication network; the method comprising:
receiving, from the network node, a message indicative of a beam power setting of the plurality of downlink beams; wherein the beam power setting comprises a power offset being applied, at the network node, to at least one downlink beam of the plurality of downlink beams; the power offset being relative to a nominal power setting of the plurality of downlink beams;
performing measurements on reference signals received from the network node;
determining the preferred downlink beam based on the measurements and the beam power setting; and
transmitting, to the network node, a report indicative of the preferred downlink beam.
