Abstract

A method and an apparatus for ACK/NACK transmission. When a terminal device only receives a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH) in which a downlink assignment index (DAI) value is equal to 1 in a feedback window, the terminal device transmits ACK/NACK feedback information corresponding to the SPS PDSCH and ACK/NACK feedback information corresponding to the PDCCH on PUCCH format 1a/1b resource using PUCCH format 1b with channel selection or ACK/NACK bundling.
