Abstract
The invention provides a method for feeding back ACK/NACK information in the process of carrier aggregation, a base station and user equipment. The method comprises the steps that public fields preset in DCI are configured into at least one of at least two ACK/NACK-feedback-related command fields; the DCI is transmitted to the user equipment so that the user equipment can feed back the ACK/NACK information according to the DCI. By means of the method, backward compatibility between ACK/NACK information feedback and an LTE system in the process of carrier aggregation can be achieved.
