a control resource set.
6 . The method of claim 1 , wherein each of the plurality of downlink channels comprises at least one of:
fewer search spaces than the second downlink channel; or
fewer control resource sets than the second downlink channel.
7 . The method of claim 1 , further comprising, based on receiving the first indication, at least one of:
stopping a secondary cell deactivation timer of a cell associated with the first power saving configuration; or
stopping a bandwidth part inactivity timer of an active bandwidth part of the cell associated with the first power saving configuration.
8 . A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, configure the wireless device to:
receive a first indication to start monitoring a first downlink channel that corresponds to a first power saving configuration of a plurality of power saving configurations, wherein the plurality of power saving configurations correspond to a plurality of downlink channels; and
receive, based on the first indication and via the first downlink channel, a second indication to monitor a second downlink channel.
9 . The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to receive, based on monitoring the second downlink channel, downlink control information.
10 . The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to:
receive, based on monitoring the second downlink channel, a downlink assignment; and
receive, based on the downlink assignment, downlink transport blocks.
11 . The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to:
receive, based on monitoring the second downlink channel, an uplink grant; and
transmit, based on the uplink grant, uplink transport blocks.
12 . The wireless device of claim 8 , wherein the first power saving configuration comprises at least one of:
a periodicity of the first downlink channel,
a duration of the first downlink channel,
a number of resource blocks in a frequency domain,
a search space set, or
a control resource set.
13 . The wireless device of claim 8 , wherein each of the plurality of downlink channels comprises at least one of:
fewer search spaces than the second downlink channel; or
fewer control resource sets than the second downlink channel.
14 . The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to, based on the first indication, perform at least one of:
stopping a secondary cell deactivation timer of a cell associated with the first power saving configuration, or
stopping a bandwidth part inactivity timer of an active bandwidth part of the cell associated with the first power saving configuration.
15 . A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:
receive a first indication to start monitoring a first downlink channel that corresponds to a first power saving configuration of a plurality of power saving configurations, wherein the plurality of power saving configurations correspond to a plurality of downlink channels; and
receive, based on the first indication and via the first downlink channel, a second indication to monitor a second downlink channel.
16 . The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, further configure the wireless device to receive, based on monitoring the second downlink channel, downlink control information.
17 . The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, further configure the wireless device to:
receive, based on monitoring the second downlink channel, a downlink assignment; and
receive, based on the downlink assignment, downlink transport blocks.
