FIRST NETWORK NODE AND METHOD IN A COMMUNICATION NETWORK FOR CONTROLLING POWER CONSUMPTION

A method performed by a first network node for controlling power consumption in a second network node in a wireless communications network is provided. The second network node is operating in a first power consumption level out of multiple power consumption levels. The first network node 111 obtains (501) one or more performance parameters related to data traffic performance of User Equipment (UE) connections served by the second network node during a time interval. The first network node 111 determines (502) a proportion of the UE connections that are associated with a performance parameter exceeding a first threshold. The determination is based on the obtained one or more performance parameters. The first network node 111 decides (503) whether or not to switch from the first power consumption level to a second power consumption level out of the multiple power consumption levels. The decision is based on the determined proportion of UE connections that are associated with a performance parameter exceeding the first threshold.
