Abstract
The invention provides a method for feeding acknowledgement (ACK)/negative acknowledgement (NACK) back during carrier aggregation, a base station and user equipment. The method comprises the following steps of: configuring a preset public field of downlink control information (DCI) in a way that the public field can be configured into at least one of at least two ACK/NACK feedback-related command fields; and transmitting the DCI to the user equipment, so that the user equipment can feed the ACK/NACK information back according to the DCI. In the embodiment of the invention, the backward compatibility of ACK/NACK information feedback and a long term evolution (LTE) system under carrier aggregation can be realized.
