1. A hybrid automatic repeat request acknowledgement (HARQ-ACK) processing method, comprising:
determining priorities of HARQ-ACK bits in a first HARQ-ACK codebook according to at least one of downlink assignment indexes (DAIs) indicated by downlink control information (DCI) corresponding to the first HARQ-ACK codebook or indexes of carriers where physical downlink shared channels (PDSCHs) corresponding to the first HARQ-ACK codebook are located;
selecting at least a part of the HARQ-ACK bits as a first HARQ-ACK bit from the first HARQ-ACK codebook according to the priorities of the HARQ-ACK bits in the first HARQ-ACK codebook and a preset configuration comprising a quantity of multiplexed HARQ-ACK bits;
performing at least one of: discarding the first HARQ-ACK bit; or
multiplexing the first HARQ-ACK bit with HARQ-ACK bits in a second HARQ-ACK codebook, wherein a priority of the first HARQ-ACK codebook is lower than a priority of the second HARQ-ACK codebook; and
after bit compression is performed on HARQ-ACK bits other than the first HARQ-ACK bit in the first HARQ-ACK codebook, multiplexing the bit-compressed HARQ-ACK bits other than the first HARQ-ACK bit in the first HARQ-ACK codebook with the HARQ-ACK bits in the second HARQ-ACK codebook.
