Abstract
The invention provides a method for feeding back ACK/NACK information under carrier aggregation, a base station, and user equipment. The method includes: configuring a common field preset in DCI as at least one of at least two ACK/NACK feedback-related command fields, to which the common field is able to be configured; and sending the DCI to user equipment, such that the user equipment feeds back ACK/NACK information according to the DCI. According to embodiments of the invention, it can be realized that the ACK/NACK information feedback under carrier aggregation is backward compatible with an LTE system.
