Abstract
Secondary cell management in wireless communications is described. A plurality of cells may be grouped into a plurality of groups that comprise a primary group comprising a primary cell with a primary control channel, and a secondary group comprising a plurality of secondary cells. The secondary group may comprise a first secondary cell with a secondary control channel The wireless device may keep the first secondary cell active based on a secondary cell in the secondary group being active.

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, from a base station:
- configuration parameters of a plurality of cells that are grouped into:
- a primary group comprising a primary cell configured with a primary control channel;
- and
- a secondary group comprising:
- a first secondary cell configured with a secondary control channel;
- and
- a second secondary cell different from the first secondary cell;
- and
- a deactivation timer value for a deactivation timer associated with at least one secondary cell of the secondary group;
- keep the first secondary cell active based on the second secondary cell being active;
- and
- deactivate the first secondary cell after deactivation of each other secondary cell of the secondary group.

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, to a wireless device:
- configuration parameters of a plurality of cells that are grouped into:
- a primary group comprising a primary cell configured with a primary control channel;
- and
- a secondary group comprising:
- a first secondary cell configured with a secondary control channel;
- and
- a second secondary cell different from the first secondary cell;
- and
- a deactivation timer value for a deactivation timer associated with at least one secondary cell of the secondary group;
- keep a state of the first secondary cell active based on the second secondary cell being active;
- and
- change the state of the first secondary cell to deactivated after deactivation of each other secondary cell of the secondary group.
