Summary:Embodiments presented herein relates to a method for saving power in remote radio heads (RRHs) of a wireless communication system. The method is performed in an RRH controller node associated with a plurality of RRHs or the same cell, each of the plurality of RRHs having at least a first antenna branch A of the cell and a second antenna branch B of the cell. The method comprises providing S120 a first power saving indication to a first RRH of the plurality of RRHs, to inactivate its first antenna branch A, and providing S120 a second power saving indication to a second RRH of the plurality of RRHs, to inactivate its second antenna branch B, wherein at least one antenna branch is kept active in the first and second RRH. RRH controller nodes, a computer programs and a computer program product for saving power in RRHs of a wireless communication system are also presented.
