Techniques and apparatuses for hybrid automatic repeat request acknowledgement (harq-ack) feedback for carrier aggregation in new radio

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

• memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI);
• determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI;
• and
• transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set.

A non-transitory computer-readable medium storing instructions for wireless communication, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
• determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI);
• determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI;
• and
• transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set.

An apparatus for wireless communication, comprising:

• means for determining a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI);
• means for determining a second HARQ-ACK payload for a second CC set based at least in part on a second DAI;
• and
• means for transmitting the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set.
