The invention relates to a method for configuring a set of multi-carrier power amplifiers, MCPAs, to provide power amplification for a set of base station transmitters. The method is characterized by switching at least a first MCPA in the set of multi-carrier power amplifiers such that the at least first MCPA stops providing power amplification to at least a first subset of the set of base station transmitters, and switching at least a second MCPA in the set of multi-carrier power amplifiers such that the at least second MCPA starts to provide power amplification to the at least first subset of the set of base station transmitters. The invention also relates to a distributing unit connectable to such a base station and a base station comprising a distributing unit.
