INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Methods and systems are provided for NES (network energy savings) operations in a network. A network node may transmit to user equipments (UEs) an indication about an NES operation activation for one or more cells. The UE(s) may send a reconfiguration request to modify the NES operation for one or more cells, for example to avoid a degradation in service that may negatively impact key performance indicators or quality of experience. In response, the network node may modify the NES operation. The network node may then send an updated indication about the modified NES operation for the one or more cells. ## Claims ### Claim 1 A method performed by a user equipment, UE, for preference signaling regarding Network Energy Saving, NES, operation, comprising: receiving from a network node an indication about an NES operation activation for one or more cells;
