Dynamic decoding timeline systems and methods

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a network entity, control information scheduling a downlink transmission and indicating a first feedback resource for a first decoding scheme of the UE and a second feedback resource for a second decoding scheme of the UE;
• receive, from the network entity, the downlink transmission;
• decode the downlink transmission using at least one of the first decoding scheme or the second decoding scheme;
• and
• transmit, to the network entity, an indicator that the first ACK/NACK response using the second feedback resource is pending using the first feedback resource;
• transmit, to the network entity, a first acknowledgement/negative acknowledgement (ACK/NACK) response based on the decoded downlink transmission using the first feedback resource if decoding the downlink transmission using the first decoding scheme or using the second feedback resource if decoding the downlink transmission using the second decoding scheme.

An apparatus for wireless communication at a network entity, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive timing information for a user equipment (UE) indicating a first minimum K1 value associated with a first decoding scheme and a second minimum K1 value associated with a second decoding scheme;
• transmit control information for a downlink transmission of the UE indicating a first feedback resource based on the first minimum K1 value and a second feedback resource based on the second minimum K1 value;
• transmit the downlink transmission of the UE;
• receive an ACK/NACK response for the downlink transmission using the first feedback resource or the second feedback resource;
• and
• retransmit the downlink transmission of the UE after receiving the ACK/NACK response for the downlink transmission using the first feedback resource in response to determining that the ACK/NACK response comprises a NACK, wherein the first feedback resource is temporally before the second feedback resource.

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

• receiving, from a network entity, control information scheduling a downlink transmission and indicating a first feedback resource for a first decoding scheme of the UE and a second feedback resource for a second decoding scheme of the UE;
• transmitting, to the network entity, a first conditional trigger associated with the first decoding scheme, wherein decoding the downlink transmission using at least one of the first decoding scheme or the second decoding scheme comprises decoding the downlink transmission using the first decoding scheme if one or more environmental conditions satisfies the first conditional trigger;
• receiving, from the network entity, the downlink transmission;
• decoding the downlink transmission using at least one of the first decoding scheme or the second decoding scheme;
• and
• transmitting, to the network entity, a first ACK/NACK response based on the decoded downlink transmission using the first feedback resource if decoding the downlink transmission using the first decoding scheme or using the second feedback resource if decoding the downlink transmission using the second decoding scheme.
