Abstract
PROBLEM TO BE SOLVED: To provide a method, a base station and user equipment for feeding back on an ACK/NACK message during carrier aggregation.SOLUTION: The method includes: a step 11 of configuring a common field preset in downlink control information (DCI) that is at least one type of command field related to ACK/NACK feedback into at least two types of command fields related to ACK/NACK feedback, where the common field can be configured as the command fields related to ACK/NACK feedback; and a step 12 of transmitting DCI to user equipment so that the user equipment can feed back an ACK/NACK message according to the DCI. The present invention may realize backward compatibility of ACK/NACK message feedback with a long term evolution (LTE) system in carrier aggregation.
