Abstract  Abstract

The present invention provides a method, a base station, and user equipment for feeding back ACK / NACK information for a carrier set. The method comprises: configuring a common field preset in the DCI as at least one type of command field related to ACK / NACK feedback among at least two types of command fields related to ACK / NACK feedback, wherein the public field is an ACK / NACK. May be configured as public fields related to feedback; And sending the DCI to user equipment, causing the user equipment to feed back the ACK / NACK information according to the DCI. The present invention can implement backward compatibility for the feedback of the ACK / NACK information in the carrier set for the LTE system.
