Abstract
There is provided a method for adjusting beam gain in a radio network node comprising a plurality of antenna elements. The radio network node is configured with a codebook comprising a plurality of predetermined precoding matrices. The method comprises: determining a direction from the radio network node to a target wireless device, and a configured beam gain value in the determined direction; adapting one or more of the plurality of predetermined precoding matrices to generate an adapted precoding matrix in which the beam gain is maximal in the determined direction and equal to or less than the configured beam gain value; and applying the adapted precoding matrix to signals output to the plurality of antenna elements for transmission to the target wireless device.
