Claim 0:
1. A method for wireless communication by a base station (BS), the method comprising:
indicating, to a user equipment (UE), 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, wherein the codebook includes a plurality of codepoints;
determining a set of ambiguous codepoints of the plurality of codepoints, wherein the set of ambiguous codepoints includes a first combination of codepoints and a second combination of codepoints, wherein the second combination of codepoints is different from the first combination of codepoints, and wherein determining the set of ambiguous codepoints comprises determining the set of ambiguous codepoints based on first HARQ feedback calculated from the first combination of codepoints being equal to second HARQ feedback calculated from the second combination of codepoints; and
selecting an action to perform for scheduling downlink data transmissions based on the set of ambiguous codepoints.
