Method performed by a first network node, connected to a second network node serving a wireless device in a first cell. The first cell has a second cell as neighbor. Each cell has a first beamforming configuration for a first use corresponding to a first beam gain, and a second configuration for a second use corresponding to a second gain. The first network node obtains, for each cell, a first indication of the second gain in relation to the first. The first network node also determines, based on the first indication, a first value to be applied in a cell selection procedure between the first and the second cell. The first network node initiates sending the second indication of the first value, or a third indication of the first indication.
