Network energy saving for bandwidth part
A wireless device receives one or more radio resource control (RRC) messages. The one or more RRC messages indicate a scheduling request (SR) configuration of a cell and configuration parameters of a group common downlink control information (DCI) indicating an energy saving state of the cell.
