Claim 3:
4. A method performed by a user equipment (UE), the method comprising:
receiving at least one downlink transmission;
receiving an indicator indicating whether to generate a second hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) sub-codebook, wherein the second HARQ-ACK sub-codebook comprises HARQ-ACK information bits with each bit corresponding to one code block group of one transport block of the at least one downlink transmission;
generating a first HARQ-ACK sub-codebook comprising HARQ-ACK information bits with each bit corresponding to one transport block of the at least one downlink transmission;
determining whether to generate the second HARQ-ACK sub-codebook based on the indicator;
transmitting a HARQ-ACK codebook comprising only the first HARQ-ACK sub-codebook in response to determining not to generate the second HARQ-ACK sub-codebook or transmit both the first HARQ-ACK sub-codebook and the second HARQ-ACK sub-codebook in response to determining to generate the second HARQ-ACK sub-codebook; and
in response to there being a single downlink transmission transmitted on a carrier configured with transport block-based transmission or transmitted on a carrier configured with code block group-based transmission and scheduled by a downlink control information format 1_0 and the indicator indicating not to generate the second HARQ-ACK sub-codebook, determining a transport block based HARQ-ACK information bit for the downlink transmission included in the first HARQ-ACK sub-codebook and the HARQ-ACK codebook comprising only the first HARQ-ACK sub-codebook.
