METHODS, BASE STATIONS AND USER EQUIPMENT FOR ACKNOWLEDGMENT/NEGATIVE ACKNOWLEDGMENT FEEDBACK ON A PHYSICAL UPLINK CONTROL CHANNEL

摘要

The present invention discloses a method and system for feeding back an acknowledgement/negative-acknowledgement response message on a physical uplink control channel. The method includes: sending, by a user equipment, an acknowledgement/ negative-acknowledgement response message by adopting a manner based on a channel selection or based on a DFT-s-OFDM in a multiplexing mode according to a feedback manner or a feedback rule in the multiplexing mode configured by a base station. The present invention provides a solution for feeding back an acknowledgement/negative-acknowledgement response message on a physical uplink control channel in a carrier aggregation scenario, in which, the base station can configure for the user equipment and directly indicate to the user equipment through the higher layer signaling the feedback manner in the multiplexing mode, and can also configure the feedback rule in the multiplexing mode for the user equipment; and the user equipment determines the feedback manner in the multiplexing mode according to the feedback manner or feedback rule configured by the base station.
