The SCell configuration information contains group numbers and indices of SCells associated with the BS and the micro BS, respectively, and indicates a secondary primary cell (S-PCell) associated with the micro BS. The present invention also provides a BS and a UE. With the method for component carrier configuration and the corresponding BS and UE according to the present invention, the channel state information of the UE can be fed back on an uplink working of the micro cell base station.
