Abstract
A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.

1-12. (canceled)
A method for configuring, by a user equipment (UE), a cell in a wireless communication system, the method comprising:
- receiving, from a base station, a secondary cell (SCell) configuration for configuring a new SCell and initial state information of the new SCell,
- wherein the initial state information of the new SCell includes either an activated state or a dormant state;
- configuring the new SCell based on the SCell configuration;
- when the initial state information of the new SCell includes the activated state:
- determining that an initial state of the new SCell is in the activated state upon configuring the new SCell, and
- transmitting or receiving data via the new SCell which is activated upon configuring the new SCell;
- and
- when the initial state information of the new SCell includes the dormant state:
- determining that the initial state of the new SCell is in the dormant state upon configuring the new SCell,
- receiving information for activating the new SCell determined to be in the dormant state,
- activating the new SCell determined to be in the dormant state based on the information, and
- transmitting or receiving data via the new SCell which is activated based on the information.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor, connected with the memory and the transceiver, that:
- controls the transceiver to receive, from a base station, a secondary cell (SCell) configuration for configuring a new SCell and initial state information of the new SCell,
- wherein the initial state information of the new SCell includes either an activated state or a dormant state;
- configures the new SCell based on the SCell configuration;
- when the initial state information of the new SCell includes the activated state:
- determines that an initial state of the new SCell is in the activated state upon configuring the new SCell, and
- controls the transceiver to transmit or receive data via the new SCell which is activated upon configuring the new SCell;
- and
- when the initial state information of the new SCell includes the dormant state:
- determines that the initial state of the new SCell is in the dormant state upon configuring the new SCell,
- controls the transceiver to receive information for activating the new SCell determined to be in the dormant state,
- activates the new SCell determined to be in the dormant state based on the information, and
- controls the transceiver to transmit or receive data via the new SCell which is activated based on the information.
