Multiplexing two part hybrid automatic repeat request acknowledgement (harq-ack)

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

• receiving, from a network node, a group of downlink transmissions;
• forming a first hybrid automatic repeat request acknowledgement (HARQ-ACK) part and a second HARQ-ACK part associated with a first HARQ-ACK payload in accordance with a transformation scheme, the first HARQ-ACK payload including HARQ feedback for each one of the group of downlink transmissions, a size of the second HARQ-ACK part being a function of the first HARQ-ACK part;
• separately encoding the first HARQ-ACK part and the second HARQ-ACK part;
• multiplexing the encoded second HARQ-ACK part on a physical uplink shared channel (PUSCH);
• transmitting, to the network node via a physical uplink control channel (PUCCH), the first HARQ-ACK part;
• and
• transmitting, to the network node via the PUSCH, the multiplexed second HARQ-ACK part.

A user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors and storing processor-executable code that, when executed by the one or more processors, is configured to cause the UE to:
• receive, from a network node, a group of downlink transmissions;
• form a first hybrid automatic repeat request acknowledgement (HARQ-ACK) part and a second HARQ-ACK part associated with a HARQ-ACK payload in accordance with a transformation scheme, the HARQ-ACK payload including HARQ feedback for each one of the group of downlink transmissions, a size of the second HARQ-ACK part being a function of the first HARQ-ACK part;

• multiplex the encoded first HARQ-ACK part and the encoded second HARQ-ACK part on a physical uplink shared channel (PUSCH);
• and
• transmit, to the network node via the PUSCH, the multiplexed first HARQ-ACK part and second HARQ-ACK part.
