Method for communicating with data through component carriers in mobile communication system to which carrier aggregation method is applied and apparatus therefor
The present invention relates to a method for enabling a terminal to communicate with data by modifying an association relationship among component carriers in a mobile communication system supporting carrier aggregation and an apparatus therefor. The method in accordance with one embodiment of the present invention, comprises: receiving a message including identifier information for modifying an association relationship among at least one downlink component carrier and at least one uplink component carrier from a base station; receiving predetermined data through at least one downlink component carrier from the base station; and transmitting feedback data to the base station for data received through the uplink component carrier modified according to the identifier information.
1. A method for configuring component carriers at a user equipment in a mobile communication system supporting carrier aggregation, the method comprising:
receiving a message including configuration information for a first component carrier; and
modifying configuration of the component carriers according to the configuration information,
wherein the configuration information includes identification information of a second component carrier, and
wherein the identification information indicates an association between the first component carrier and the second component carrier.
2. The method of claim 1 , wherein the message includes information for reconfiguring radio resource control (RRC) connection of the user equipment.
3. The method of claim 1 , wherein downlink of the first component carrier is associated with uplink of the second component carrier.
4. The method of claim 1 , wherein uplink of the first component carrier is associated with downlink of the second component carrier.
5. The method of claim 1 , wherein the identification information indicates that downlink of the second component carrier is used to measure path loss for uplink of the first component carrier.
6. A communication device configuring component carriers in a mobile communication system supporting carrier aggregation, the communication device comprising:
a receiving module; and
a processor configured to:
receive a message including configuration information for a first component carrier, and
modify configuration of the component carriers according to the configuration information,
wherein the configuration information includes identification information of a second component carrier, and
wherein the first component carrier is associated with the second component carrier according to the identification information.
7. The communication device of claim 6 , wherein the message includes information for reconfiguring radio resource control (RRC) connection of the user equipment.
8. The communication device of claim 6 , wherein downlink of the first component carrier is associated with uplink of the second component carrier.
9. The communication device of claim 6 , wherein uplink of the first component carrier is associated with downlink of the second component carrier.
10. The communication device of claim 6 , wherein the identification information indicates that downlink of the second component carrier is used to measure path loss for uplink of the first component carrier.
