identifying a plurality of time domain resource allocation (TDRA) candidate occasions, each TDRA candidate occasion occurring within a different respective one of a plurality of mini-slots, each of the plurality of mini-slots carrying a different respective one of a plurality of downlink channel repetitions;

maintaining, in a TDRA table, TDRA entries including location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions, when at least one of the plurality of downlink channel repetitions is not decoded;

extending the TDRA table such that a first part of the extended TDRA table comprises a TDRA entry associated with a first downlink channel repetition and a second part of the extended TDRA table comprises a composite TDRA entry determined based on a combination of the plurality of downlink channel repetitions including at least the first downlink channel repetition and a second downlink channel repetition; and

determining an acknowledgment/negative-acknowledgment (ACK/NACK) bit position to associate with the composite TDRA entry based on a starting symbol of the composite TDRA entry and an entry length of the composite TDRA entry.
