Abstract
Provided is a method of controlling states of a secondary cell by a user equipment. The method may include receiving SCell state indication information indicating a state for the SCell from a base station through an RRC message or a MAC control element, configuring the state of the SCell in an activation state or a dormant state on the basis of the SCell state indication information, and transmitting channel state information for the SCell to the base station in accordance with CQI configuration information configured for the SCell.
Claims14
A method of controlling states of a secondary cell (SCell) by a user equipment, the method comprising:
- receiving SCell state indication information indicating a state for the SCell from a base station through a radio resource control (RRC) message or a medium access control (MAC) control element;
- configuring the state of the SCell in one of an activation state and a dormant state based on the SCell state indication information;
- and
- transmitting channel state information for the SCell to the base station in accordance with channel quality indicator (CQI) configuration information configured for the SCell,
- wherein the transmitting comprises:
- transmitting channel state information for the SCell to the base station by applying a value of a first activation state CQI report parameter contained in a first CQI configuration information when the first CQI configuration information for the SCell is configured in the user equipment, and
- transmitting channel state information for the SCell to the base station by applying a value of a second CQI report parameter contained in second CQI configuration information when the first CQI configuration information is not configured in the user equipment, and
- wherein:
- the first CQI configuration information and the second CQI configuration information comprise different CQI report periods and offset values;
- and
- the CQI report period contained in the first CQI configuration information is set as a shorter value than the CQI report period contained in the second CQI configuration information.

A method of controlling states of a secondary cell (SCell) of a user equipment by base station, the method comprising:
- transmitting secondary cell (SCell) state indication information indicating a state for a SCell to the user equipment through one of a radio resource control (RRC) message and a medium access control (MAC) control element;
- and
- receiving channel state information for the SCell in accordance with channel quality indicator (CQI) configuration information configured for the SCell when the state of the SCell is configured in an activation state or a dormant state on the basis of the SCell state indication information,
- wherein when the state of the SCell is configured in the activation state, the receiving comprises:
- receiving channel state information for the SCell in accordance with a value of a first activation state CQI report parameter contained in a first CQI configuration information when the first CQI configuration information for the SCell is configured in the user equipment, and
- receiving channel state information for the SCell in accordance with a value of a second CQI report parameter contained in second CQI configuration information when the first CQI configuration information is not configured in the user equipment, and
- wherein the receiving comprises receiving the channel state information in accordance with the second CQI configuration information when the first CQI configuration information configured in the user equipment is expired and when the channel state information in accordance with the first CQI configuration information is received.
