Modifying a hybrid automatic repeat request acknowledgement (harq-ack) payload prior to forming a two part harq-ack

A method for wireless communication by a UE, comprising:

• receiving, from a network node, a group of downlink transmissions;
• modifying an original HARQ-ACK payload that includes HARQ feedback for each one of the group of downlink transmissions;
• forming, from the modified original HARQ-ACK payload, a first HARQ-ACK part and a second HARQ-ACK part, 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;
• and
• transmitting the encoded first HARQ-ACK part and the encoded second HARQ-ACK part.

A method for wireless communication by a UE, comprising:

• receiving, from a network node, a group of downlink transmissions;
• generating, from an original HARQ-ACK payload, a first portion and a second portion, the original HARQ-ACK payload including HARQ feedback for each one of the group of downlink transmissions;
• forming, from the second portion, a first HARQ-ACK part and a second HARQ-ACK part, a size of the second HARQ-ACK part being a function of the first HARQ-ACK part;
• and
• transmitting the first HARQ-ACK part, the second HARQ-ACK part, and the first portion in accordance with the forming.

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, from an original HARQ-ACK payload, a first HARQ-ACK part and a second HARQ-ACK part in accordance with satisfying a forming condition, the original 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 encode the first HARQ-ACK part and the second HARQ-ACK part;
• and
• transmit the encoded first HARQ-ACK part and the encoded second HARQ-ACK part.
