Abstract
Disclosed are an ACK/NACK feedback information transmission method and device. Application of the technical solution in the embodiments of the present invention enables indication of PUCCH format 3 channel resources by means of the PDCCH which corresponds to the PDSCH transmission in a downlink main carrier having a DAI value greater than 1 and/or which instructs release of downlink SPS resources and of information in the ACK/NACK resource assignment domain of the PDCCH which corresponds to the PDSCH transmission in the downlink subordinate carrier thus allowing a terminal device configured with a plurality of downlink carriers also to transmit ACK/NACK feedback information using PUCCH format 3 while only receiving data from the downlink main carrier. This avoids an inconsistent understanding of ACK/NACK feedback transmission formats between the base station and the terminal device and improves the reliability and efficiency of ACK/NACK feedback transmission.
