METHOD AND APPARATUS OF COMMUNICATION

摘要

An improved aperiodic downlink channel quality reporting in a radio communication system utilizing carrier aggregation is disclosed. In the radio communication system, a number of downlink component carriers can be aggregated for communication between a network node and a User Equipment (UE). The invention is characterized in that a set of downlink component carriers is determined from the number of downlink component carriers, a downlink control channel for the UE is arranged to include information being usable for identifying at least one downlink component carrier of the 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.
