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.
A method for saving power in remote radio heads, RRHs, of a wireless communication system, the method being performed in an RRH controller node associated with a plurality of RRHs for 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 comprising:
A remote radio head, RRH, controller node for saving power in RRHs of a wireless communication system, the RRH controller node being associated with a plurality of RRHs for 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 RRH controller node comprising:
A remote radio head, RRH, controller node for saving power in RRHs of a wireless communication system, the RRH controller node being associated with a plurality of RRHs for 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 RRH controller node comprising:
A non-transitory computer program for saving power in remote radio heads, RRHs, of a wireless communication system, wherein an RRH controller node is associated with a plurality of RRHs for 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 non-transitory computer program comprising computer program code which, when run in the RRH controller node, causes the RRH controller node to:
