Claim 8:
9. A method for wireless communication by a user equipment (UE), the method comprising:
receiving, from a base station (BS), an indication of a codebook for uplink transmission of hybrid automatic repeat request (HARQ) feedback, the codebook based on: (i) a number (M) of candidate downlink transmission occasions for a time period, and (ii) a maximum number (k) of downlink transmissions the UE can receive during the time period, the codebook comprising: (i) a first plurality of codepoints, (ii) a second plurality of codepoints, (iii) a third plurality of codepoints, and (iv) another one or more codepoints;
receiving a downlink transmission over the time period; and
transmitting HARQ feedback for the downlink transmission, the HARQ feedback calculated using the first plurality of codepoints, the second plurality of codepoints, or the third plurality of codepoints if a codepoint location is ambiguous, wherein the codepoint location is ambiguous based on first HARQ feedback calculated from the codepoint location being equal to second HARQ feedback calculated from another codepoint location.
