Abstract: Certain aspects of the present disclosure provide techniques for reducing a size of semistatic codebooks for HARQ feedback. A method that may be performed by a user equipment (UE) includes determining a number (M) of candidate downlink transmission occasions for a time period, determining a maximum number (k) of simultaneous downlink transmissions the UE can receive during the time period, receiving one or more downlink transmissions during the time period from a base station, and determining a type of encoding for the HARQ feedback based on: (i) a number of the one or more downlink transmissions received, (ii) the number (M) of candidate downlink transmission occasions for the time period, and/or (iii) the maximum number (k) of simultaneous downlink transmissions.
