Abstract
A wireless device receives a downlink control information (DCI) on a primary cell. The DCI may comprise a field instructing a wireless device to activate a secondary cell. The wireless device activates the secondary cell in response to receiving the DCI.
Claims37
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, one or more messages comprising configuration parameters of a cell, wherein the configuration parameters comprise:
- a first value for a first timer;
- and
- a second value for a second timer, wherein the second timer is associated with monitoring a downlink control channel;
- receive a medium-access control (MAC) control element (CE) indicating an activation of the cell;
- based on the MAC CE:
- activate the cell;
- and
- start the first timer;
- receive first downlink control information (DCI) indicating monitoring of the downlink control channel;
- based on the first DCI:
- start the second timer;
- and
- monitor the downlink control channel;
- and
- receive, while the first timer and the second timer are both running, second DCI comprising one or more of a downlink assignment or an uplink grant.

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, one or more messages comprising configuration parameters of a cell, wherein the configuration parameters comprise:
- a first value for a first timer;
- and
- a second value for a second timer, wherein the second timer is associated with the wireless device monitoring a downlink control channel;
- transmit a medium-access control (MAC) control element (CE) indicating an activation of the cell;
- based on the MAC CE:
- activate the cell for the wireless device;
- and
- start the first timer;
- transmit first downlink control information (DCI) indicating monitoring of the downlink control channel;
- based on the first DCI, start the second timer associated with the wireless device monitoring the downlink control channel;
- and
- transmit, while the first timer and the second timer are both running, second DCI comprising one or more of a downlink assignment or an uplink grant.
13 more elements
A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:
- receive, from a base station, one or more messages comprising configuration parameters of a cell, wherein the configuration parameters comprise:
- a first value for a first timer;
- and
- a second value for a second timer, wherein the second timer is associated with monitoring a downlink control channel;
- receive a medium-access control (MAC) control element (CE) indicating an activation of the cell;
- based on the MAC CE:
- activate the cell;
- and
- start the first timer;
- receive first downlink control information (DCI) indicating monitoring of the downlink control channel;
- based on the first DCI:
- start the second timer;
- and
- monitor the downlink control channel;
- and
- receive, while the first timer and the second timer are both running, second DCI comprising one or more of a downlink assignment or an uplink grant.
13 more elements
A non-transitory computer-readable medium storing instructions that, when executed, configure a base station to:
- transmit, to a wireless device, one or more messages comprising configuration parameters of a cell, wherein the configuration parameters comprise:
- a first value for a first timer;
- and
- a second value for a second timer, wherein the second timer is associated with the wireless device monitoring a downlink control channel;
- transmit a medium-access control (MAC) control element (CE) indicating an activation of the cell;
- based on the MAC CE:
- activate the cell for the wireless device;
- and
- start the first timer;
- transmit first downlink control information (DCI) indicating monitoring of the downlink control channel;
- based on the first DCI, start the second timer associated with the wireless device monitoring the downlink control channel;
- and
- transmit, while the first timer and the second timer are both running, second DCI comprising one or more of a downlink assignment or an uplink grant.
10 more elements
A system comprising:
- a base station configured to:
- send one or more messages comprising configuration parameters of a cell, wherein the configuration parameters comprise:
- a first value for a first timer;
- and
- a second value for a second timer, wherein the second timer is associated with monitoring a downlink control channel;
- and
- a wireless device configured to:
- receive, from the base station, the one or more messages comprising the configuration parameters;
- receive a medium-access control (MAC) control element (CE) indicating an activation of the cell;
- based on the MAC CE:
- activate the cell;
- and
- start the first timer;
- receive first downlink control information (DCI) indicating monitoring of the downlink control channel
- based on the first DCI:
- start the second timer;
- and
