Abstract
A link quality reporting method and apparatus, and a carrier selection method and apparatus, for a multicarrier communication system utilizing carrier aggregation are disclosed. In the system, the user equipment measures, for each component carrier divided into a Physical Downlink Shared Channel (PDSCH) resource region and a Physical Downlink Control Channel (PDCCH) resource region, link quality of the PDSCH resource region and the PDCCH resource region of the component carrier and sends measured link quality information as feedback information to the base station, and the base station adaptively selects a set of component carriers for control information transmission (i.e., a PDCCH Component Carrier (CC) SET) and a set of component carriers for data transmission (i.e., a DownLink (DL) CC SET) on the basis of the feedback information.
