Abstract
A method performed by a user equipment (UE) in a wireless communication system includes receiving, from a base station, a first activation/deactivation medium access control (MAC) control element (CE), the first activation/deactivation MAC CE including a first field for indicating an activation/deactivation status of a secondary cell (SCell), wherein, in case that the first field is set to 1 and the SCell is in an activated state or a deactivated state, the SCell is activated, wherein, in case that the first field is set to 1 and the SCell is in a dormant state, the first field is ignored, and wherein, in case that the first field is set to 0, the SCell is deactivated.

A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, a first activation/deactivation medium access control (MAC) control element (CE), the first activation/deactivation MAC CE including a first field for indicating an activation/deactivation status of a secondary cell (SCell),
- wherein, in case that the first field is set to 1 and the SCell is in an activated state or a deactivated state, the SCell is activated,
- wherein, in case that the first field is set to 1 and the SCell is in a dormant state, the first field is ignored, and
- wherein, in case that the first field is set to 0, the SCell is deactivated.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), a first activation/deactivation medium access control (MAC) control element (CE), the first activation/deactivation MAC CE including a first field for indicating an activation/deactivation status of a secondary cell (SCell),
- wherein, in case that the first field is set to 1 and the SCell is in an activated state or a deactivated state, the SCell is activated,
- wherein, in case that the first field is set to 1 and the SCell is in a dormant state, the first field is ignored, and
- wherein, in case that the first field is set to 0, the SCell is deactivated.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- receive, from a base station, a first activation/deactivation medium access control (MAC) control element (CE), the first activation/deactivation MAC CE including a first field for indicating an activation/deactivation status of a secondary cell (SCell),
- wherein, in case that the first field is set to 1 and the SCell is in an activated state or a deactivated state, the SCell is activated,
- wherein, in case that the first field is set to 1 and the SCell is in a dormant state, the first field is ignored, and
- wherein, in case that the first field is set to 0, the SCell is deactivated.
A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- transmit, to a user equipment (UE), a first activation/deactivation medium access control (MAC) control element (CE), the first activation/deactivation MAC CE including a first field for indicating an activation/deactivation status of a secondary cell (SCell),
- wherein, in case that the first field is set to 1 and the SCell is in an activated state or a deactivated state, the SCell is activated,
- wherein, in case that the first field is set to 1 and the SCell is in a dormant state, the first field is ignored, and
- wherein, in case that the first field is set to 0, the SCell is deactivated.
