METHOD AND APPARATUS FOR FEEDING BACK ACK/NACK INFORMATION

摘要

A method for feeding Acknowledgement/ Negative Acknowledgement (ACK/NACK) information by a User Equipment (UE) in a wireless communication system includes: the UE configured to receive Physical Downlink Control Channel (PDCCH) information from a base station (BS). The UE also receives downlink data from the BS based on the PDCCH information. The UE generates an ACK/NACK feedback information corresponding to the downlink data. Thereafter, the UE determines a feedback status of the UE from among a plurality of feedback statuses according to a number of consecutive ACKs starting from a first data sub-frame in a binding window of the ACK/NACK feedback information. Further, the UE feeds back information on the determined feedback status to the BS.
