Abstract
The present invention relates to triggering, in a terminal of a communication system, channel quality feedback reporting for at least one of plural component carriers of the communication system available for downlink transmission. The at least one component carrier is selected based on the downlink traffic of the terminal. Reporting of the channel quality information is triggered by dedicated control information received by the terminal.

16. A method for reporting a downlink channel quality experienced by a terminal by means of channel quality information for at least one of plural component carriers of a communication system available for downlink transmission to the terminal, the method comprising the following steps performed by the terminal:
-
receiving dedicated control information having a predetermined format, wherein said dedicated control information comprises a channel quality information request flag for requesting channel quality reporting by the terminal, if said channel quality information request flag is set, selecting out of a plurality of component carriers configured in the communication system at least one component carrier based on downlink traffic, and transmitting channel quality information for each selected component carrier. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 31)

26. A method for triggering aperiodic channel quality information of a terminal on at least one component carrier available for downlink transmission to the terminal in a communication system, the method comprising the following steps performed by a node in an access network of the communication system:
-
selecting out of a plurality of component carriers configured in the communication system at least one component carrier based on downlink traffic, transmitting to the mobile terminal dedicated control information having a predetermined format comprising a channel quality information request flag that is set by the node in order to trigger aperiodic channel quality information, and receiving from the mobile terminal, in response to the dedicated control information, channel quality information for each selected component carrier. - View Dependent Claims (27, 28, 29, 30)

32. A terminal for reporting a downlink channel quality experienced by the terminal by means of channel quality information for at least one of plural component carriers of a communication system available for downlink transmission to the terminal, the terminal comprising:
-
a receiver for receiving dedicated control information having a predetermined format, wherein said dedicated control information comprises a channel quality information request flag for requesting channel quality reporting by the terminal, a processing unit for selecting, if said channel quality information request flag is set, out of a plurality of component carriers configured in the communication system at least one component carrier based on downlink traffic, and a transmitter for transmitting channel quality information for each selected component carrier.
