Abstract
Provided is a method and an apparatus for changing or controlling a state of a secondary cell in carrier aggregation. The method includes receiving secondary cell (SCell) state indication information indicating a state for a SCell from a base station through an RRC message or an MAC control element, causing a state of the SCell to transition into a dormant state when the SCell state indication information indicates the dormant state, and transmitting channel state information reporting for the SCell in the dormant state according to an dormant state CQI report period parameter set separately from an activation state CQI report period parameter.
Claims20
A method of controlling states of a secondary cell by a user equipment, the method comprising:
- receiving secondary cell (SCell) state indication information indicating a state for the SCell from a base station through an radio resource control (RRC) message or a medium access control (MAC) control element;
- causing a state of the SCell to transition into a dormant state when the SCell state indication information indicates the dormant state;
- and
- transmitting channel state information reporting for the SCell in the dormant state according to a dormant state channel quality indicator (CQI) report period parameter set separately from an activation state CQI report period parameter.
A method of controlling states of a secondary cell by a base station, the method comprising:
- transmitting secondary cell (SCell) state indication information indicating a state for the SCell to a user equipment through an radio resource control (RRC) message or a medium access control (MAC) control element;
- and
- when the SCell is configured to be in a dormant state according to the SCell state indication information, receiving channel state information reporting for the SCell in the dormant state according to a dormant state CQI report period parameter set separately from a activation state CQI report period parameter.
A user equipment controlling states of a secondary cell, the user equipment comprising:
- a receiver configured to receive secondary cell (SCell) state indication information indicating a state for the SCell from a base station through an radio resource control (RRC) message or a medium access control (MAC) control element;
- a controller configured to cause a state of the SCell to transition into a dormant state when the SCell state indication information indicates the dormant state;
- and
- a transmitter configured to transmit channel state information reporting for the SCell in the dormant state according to a dormant state channel quality indicator (CQI) report period parameter set separately from an activation state CQI report period parameter.
