A method of aperiodic downlink channel quality reporting in a radio communication system utilizing carrier aggregation, wherein a number of downlink component carriers can be aggregated for communication between a network node and a User Equipment, UE, in said system,characterized in that
- a set of downlink component carriers is determined from said number of downlink component carriers,
- a downlink control channel for said UE is arranged to include information being usable for identifying at least one downlink component carrier of said set of downlink component carriers, and
- a channel quality report is to be provided for each one of the at least one identified downlink component carrier; wherein said information is utilized for directly identifying said at least one identified downlink component carrier by indicating an enumeration corresponding to said at least one identified downlink component carrier;wherein said information is represented by more than one bit in said downlink control channel, the method further comprises:
signaling an interpretation of the more than one bit to the UE, by which the UE has knowledge of a mapping from the values of the more than one bit to an entity, from which the identified downlink component carrier is uniquely addressed. |
