Abstract:
The present invention provides a method, a base station, and a user equipment for feeding back ACK/NACK information for carrier aggregation. The method includes: configuring a common field preset in DCI as at least one type of command field related to ACK/NACK feedback of at least two types of command fields related to ACK/NACK feedback, where the common field can be configured as the command fields related to ACK/NACK feedback; and sending the DCI to a user equipment, so that the user equipment feeds back ACK/NACK information according to the DCI. The present invention may realize backward compatibility of the ACK/NACK information feedback with an LTE system in carrier aggregation.

Claim (Index 1):
A method for receiving Acknowledgement/Negative-acknowledgement (ACK/NACK) information for carrier aggregation through an uplink component carrier X, comprising:\n configuring, by a base station, one or more pieces of downlink control information (DCI) according to a type of downlink component carrier Y,\n wherein each of the one or more pieces of DCI includes a transmission power control (TPC) command field and scheduling information for a physical downlink shared channel (PDSCH), and is transmitted through a physical downlink control channel (PDCCH) corresponding to the PDSCH, wherein the PDCCH is carried on the downlink component carrier Y, \n when the downlink component carrier Y is a non-system-linked downlink component carrier of the uplink component carrier X, a first command indicated by a first TPC command field in at least one piece of the one or more pieces of DCI is an ACK resource indication (ARI) command, and the ARI command indicates which resource of a group of uplink ACK channel resources assigned through a higher-layer signaling is to be used to feed back ACK/NACK information, and \n when the downlink component carrier Y is a system-linked downlink component carrier of the uplink component carrier X, a second command indicated by a second TPC command field in at least one piece of the one or more pieces of DCI is a TPC command; \n sending, by the base station, the one or more pieces of DCI through one or more PDCCHs transmitted on the downlink component carrier Y to a user equipment; and receiving, by the base station, ACK/NACK information through the uplink component carrier X from the user equipment.
