Abstract
The invention provides a method for feeding back ACK/NACK information during carrier aggregation, a base station and a user device. The method comprises the steps: configuring a common filed preset by DCI into at least one of at least two command fields related to ACK/NACK feedback; sending the DCI to the user device so that the user equipment can feed back the ACK/NACK information according to the DCI. By means of the method for feeding back the ACK/NACK information during carrier aggregation, ACK/NACK information feedback under carrier aggregation and backward compatibility of an LTE system can be achieved.
