1. A method for transmitting a hybrid automatic repeat request (HARQ) codebook, applicable to user equipment, the method comprising:
for an information block, generating an HARQ codebook, wherein one bit of the HARQ codebook indicates whether a downlink code block group (CBG) is successfully received;
for a channel occupancy time (COT) unit, integrating a plurality of HARQ codebooks respectively corresponding to a plurality of information blocks into an integrated HARQ codebook, wherein one COT unit corresponds to a plurality of information blocks, one information block corresponds to at least one transmission block, one transmission block corresponds to at least one CBG, and one information block comprises a physical downlink control channel transmission and a physical downlink data channel transmission; and
transmitting the integrated HARQ codebook to a base station;
wherein the HARQ codebook corresponds to a matrix, a valid coordinate point in the matrix corresponds to one bit in the HARQ codebook, a maximum CBG number and a total number of downlink assignment indexes (DAI) of the information block are respectively configured as a row number and a column number of the matrix, wherein the maximum CBG number represents a maximum value of CBG numbers corresponding respectively to a plurality of transmission blocks in the information blocks;
wherein said for a COT unit, integrating a plurality of HARQ codebooks respectively corresponding to a plurality of information blocks into an integrated HARQ codebook comprises:
for the COT unit, aligning the plurality of HARQ codebooks at a matrix dot (0,0); and
performing an AND operation per bit to obtain the integrated HARQ codebook, wherein a maximum value of row numbers and a maximum value of column numbers of the plurality of HARQ codebooks are configured as a row number and a column number of the integrated HARQ codebook.
