Systems and non-periodic feedback method of carrier aggregation during

摘要

I want to provide a system and non-periodic feedback method of the present invention relates carrier aggregation time. The method of the present invention comprises, it sends a non-periodic trigger signal to the user equipment, the user equipment receives the non-periodic trigger signal, the base station, based on the non-periodic trigger signal and determines the downlink component carrier DL-CC that needs to be fed back, the user equipment comprises the step of triggering an aperiodic feedback of DL-CC was determined. In accordance with the present invention, it effectively reduced the uplink feedback of DL-CC no need to solve a problem that can not be determined whether feedback which downlink component carrier based on the non-periodic trigger signals to carrier aggregation time, and feedback The base station is able to adjust the resource allocation based on the information the user equipment is fed back, to ensure the performance of downlink data transmission.
