The present invention provides a method and device for carrier management in a carrier aggregation system. The method includes: the signaling which carries an additional carrier measurement indication is sent to a User Equipment (UE); an additional carrier measurement report is received from the UE; when the downlink traffic of the UE increases, if the recorded carriers in the current downlink carrier set of the UE can not meet the requirement of the downlink traffic data rate, according to the additional carrier measurement report, at least one additional carrier is configured and activated, and the UE is notified to perform the corresponding configuration operation. In addition, according to the measurement result and the change in the downlink traffic of the UE, the base station can also perform the deactivation, activation replacement and removal of the additional carrier for the user, and notify the UE to perform the corresponding configuration operations. According to the downlink signaling, the UE can measure the quality of the received signals of the additional carriers and control the reception of control information on the Physical Downlink control Channels (PDCCHs) of the additional carriers and the data on the physical Downlink Shared Channels (PDSCHs) of the additional carriers. The method and device for carrier management can reduce the data transmission delay and the power consumption of the UE. |
