Claim 19:
20. A system comprising:
a base station comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit a first downlink control information (DCI) to a wireless device to indicate the wireless device to activate a power saving (PS) mode; wherein the wireless device skips monitoring physical downlink control channel (PDCCH) in a discontinuous reception (DRX) active time of a DRX cycle in the PS mode;
transmit a second DCI comprising:
a bandwidth part indicator field; and
a frequency domain resource assignment field;

transition a secondary cell to a dormant state based on the frequency domain resource assignment field being set to a predefined value; and
transmit a third DCI to the wireless device to indicate the wireless device to deactivate the PS mode, wherein the first DCI and third DCI have a same DCI format; and

a wireless device comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive the first DCI and activate the PS mode; wherein the wireless device skips monitoring physical downlink control channel (PDCCH) in a discontinuous reception (DRX) active time of a DRX cycle in the PS mode;
receive the second DCI comprising:
the bandwidth part indicator field; and
the frequency domain resource assignment field;

transition the second cell to the dormant state based on the frequency domain resource assignment field being set to the predefined value; and
receive third DCI to the wireless device and deactivate the PS mode.
