1. A method for hybrid automatic repeat (HARQ) feedback, comprising:
determining, through terminal equipment, a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook according to a candidate transmission occasion, wherein the semi-static HARQ-ACK codebook is used to indicate feedback information corresponding to the candidate transmission occasion, the candidate transmission occasion comprises a transmission occasion scheduled by a downlink control information (DCI) and/or a transmission occasion of a physical downlink shared channel (PDSCH) scheduled by a semi-persistent scheduling (SPS), the transmission occasion scheduled by the DCI comprises a transmission occasion of a PDSCH scheduled by the DCI and/or a transmission occasion corresponding to SPS PDSCH deactivation information scheduled by the DCI;
performing, through the terminal equipment, HARQ feedback according to the semi-static HARQ-ACK codebook, wherein
an order of feedback information corresponding to a first transmission occasion in the semi-static HARQ-ACK codebook is determined according to at least one of an order of a higher layer signalling index corresponding to the first transmission occasion, an order of an index of a serving cell corresponding to the first transmission occasion, an order of transmission occasions in the first transmission occasion, the first transmission occasion is at least part of transmission occasions in the candidate transmission occasion,
the higher layer signalling index corresponding to the first transmission occasion comprises a first higher layer signalling index and a second higher layer signalling index, the first higher layer signalling index corresponds to at least one first control resource set (CORESET), the second higher layer signalling index corresponds to at least one second CORESET, and a value of the first higher layer signalling index is less than a value of the second higher layer signalling index;
feedback information corresponding to a transmission occasion corresponding to the first higher layer signalling index is before feedback information corresponding to a transmission occasion corresponding to the second higher layer signalling index, or
the feedback information corresponding to the transmission occasion corresponding to the first higher layer signalling index is after the feedback information corresponding to the transmission occasion corresponding to the second higher layer signalling index;
a serving cell corresponding to the transmission occasion corresponding to the first higher layer signalling index comprises a first serving cell and a second serving cell, and a value of an index of the first serving cell is less than a value of an index of the second serving cell;
feedback information corresponding to a transmission occasion corresponding to the first serving cell is before feedback information corresponding to a transmission occasion corresponding to the second serving cell, or
the feedback information corresponding to the transmission occasion corresponding to the first serving cell is after the feedback information corresponding to the transmission occasion corresponding to the second serving cell.
