METHOD AND APPARATUS FOR CARRIER MANAGEMENT IN CARRIER AGGREGATION SYSTEM Russian patent published in 2014 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication engineering for performing carrier management in a carrier aggregation system for a long term evolution (LTE) project. Disclosed is a method for carrier management in a carrier aggregation system, which comprises steps of: signalling an additional carrier measurement indication to user equipment (UE); receiving an additional carrier measurement report from the UE; when downlink traffic of the UE increases, if the recorded carriers in the current downlink carrier set of the UE cannot 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. Based on the measurement result and the change in the downlink traffic of the UE, a base station performs deactivation/activation and removal of the additional carrier. The UE measures the quality of the received signals of the additional carriers and controls reception of control information over physical downlink control channels (PDCCH) of the additional carriers and data over physical downlink shared channels (PDSCH) of the additional carriers.

EFFECT: reduced data transmission delay and UE power consumption.
