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.
Claims20
A method, comprising:
- receiving, from a base station, downlink control information (DCI) through a downlink component carrier;
- and
- feeding back Acknowledgement/Negative-acknowledgement (ACK/NACK) information according to a first command, wherein the first command is related to ACK/NACK feedback and configured in a common field in the DCI, wherein the first command is configurable to have a type of at least two types of commands related to ACK/NACK feedback, and the common field is configurable to carry the first command when the first command has any type of the at least two types of commands.
An apparatus, comprising:
- a transceiver, configured to receive, from a base station, downlink control information (DCI) through a downlink component carrier;
- and
- a processor, configured to:
- determine Acknowledgement/Negative-acknowledgement (ACK/NACK) information;
- and
- feed back, through the transceiver, the ACK/NACK information according to a first command, wherein the first command is related to ACK/NACK feedback and configured in a common field in the DCI, wherein the first command is configurable to have a type of at least two types of commands related to ACK/NACK feedback, and the common field is configurable to carry the first command when the first command has any type of the at least two types of commands.
A non-transitory computer readable storage medium storing programming for execution by a processor, the programming comprising instructions to:
- receive, from a base station, downlink control information (DCI) through a downlink component carrier;
- and
- feed back Acknowledgement/Negative-acknowledgement (ACK/NACK) information according to a first command, wherein the first command is related to ACK/NACK feedback and configured in a common field in the DCI, wherein the first command is configurable to have a type of at least two types of commands related to ACK/NACK feedback, and the common field is configurable to carry the first command when the first command has any type of the at least two types of commands.
