Abstract
This application discloses a method for a hybrid automatic repeat request (HARQ) feedback of downlink data. A terminal receives downlink data of a physical downlink shared channel (PDSCH) and downlink data of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH) from a base station. Then the terminal sends a hybrid automatic repeat request (HARQ) feedback codebook to the base station. A size of the HARQ feedback codebook is based on a state of a semi-persistent scheduling (SPS) PDSCH transmission and a total downlink assignment indicator in the downlink data of the PDCCH or the EPDCCH, and the HARQ feedback codebook comprises a HARQ bit for the SPS PDSCH transmission.
