The present disclosure relates to a booster radio base station, booster RBS, defining a booster cell in a multilayer cell structure and a method, performed in a booster RBS, of controlling energy consumption. The method comprises a step of receiving (S21) information from a macro RBS, defining a basic coverage providing macro cell, the information indicating a first power required to provide service to one or more wireless devices being served in an area at least in part overlapping the booster cell. The method also comprises the further steps of determining (S23) a macro bitrate power measure based on the received information, the macro bitrate power measure reflecting a service provisioning of the one or more wireless devices from the macro RBS and determining (S25) a booster bitrate power measure, the booster bitrate power measure reflecting a service provisioning of the one or more wireless devices from the booster RBS. An energy consumption state is selected (S27) from two or more energy consumption states for the booster RBS based on a comparison between the booster bitrate power measure and the macro bitrate power measure. The disclosure relates to a method, performed in a macro radio base station, macro RBS, defining a basic coverage providing macro cell, of controlling energy consumption of a booster radio base station. The disclosure also relates to a macro radio base station.
