Abstract
A wireless device receives one or more radio resource control message comprising configuration parameters of a plurality of cells. An activation command indicating activation of a plurality of secondary cells (SCells) of the plurality of cells is received. A first downlink control information (DCI), comprising a power saving indication bitmap, is received. Each bit of the power saving indication bitmap indicates whether to monitor a downlink control channel on a corresponding activated SCell of the plurality of SCells. The wireless device starts monitoring a downlink control channel of an activated SCell of the activated SCells, in response to a bit, of the power saving indication bitmap, corresponding to the activated SCell, indicating monitoring the downlink control channel. A second DCI is received via the downlink control channel.
