1. A method for wireless communications by a user equipment (UE), the method comprising:
receiving, from a base station, downlink control information (DCI) scheduling multiple physical downlink shared channel (PDSCH) transmissions;
determining a set of candidate PDSCH reception occasions based at least in part on a time domain resource allocation (TDRA) table comprising at least one row with multiple start and length indicator value (SLIV) indexes;
receiving, from the base station, an indication of an invalid symbol of a first candidate PDSCH reception occasion of the set of candidate PDSCH reception occasions that is derived from a row r in the TDRA table;
generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook based on the set of candidate PDSCH reception occasions and according to the indication of the invalid symbol; and
providing acknowledgment/negative acknowledgement (ACK/NACK) feedback to the base station according to the HARQ-ACK codebook.
