HARQ feedback reporting for cross-carrier scheduling

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a plurality of physical downlink control channel (PDCCH) communications in a same PDCCH monitoring occasion in a first cell;
• and
• receiving a plurality of physical downlink shared channel (PDSCH) communications in at least one of the first cell or a second cell,
• wherein each of the plurality of PDCCH communications schedules a respective PDSCH communication of the plurality of PDSCH communications, and
• wherein a PDCCH communication, of the plurality of PDCCH communications, includes an indication of a counter downlink assignment index (DAI) that is based at least in part on:
• a combination of a starting symbol and a cell in which an associated PDSCH communication, of the plurality of PDSCH communications, is to be transmitted,
• a cell index of the cell in which the associated PDSCH communication is to be transmitted, and
• the PDCCH monitoring occasion.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a plurality of physical downlink control channel (PDCCH) communications in a same PDCCH monitoring occasion in a first cell;
• and
• receive a plurality of physical downlink shared channel (PDSCH) communications in at least one of the first cell or a second cell,
• wherein each of the plurality of PDCCH communications schedules a respective PDSCH communication of the plurality of PDSCH communications, and
• wherein a PDCCH communication, of the plurality of PDCCH communications, includes an indication of a counter downlink assignment index (DAI) that is based at least in part on:
• a combination of a starting symbol and a cell in which an associated PDSCH communication, of the plurality of PDSCH communications, is to be transmitted,
• a cell index of the cell in which the associated PDSCH communication is to be transmitted, and the PDCCH monitoring occasion.
