Flexible feedback with outer coding

A method for wireless communications at a network node, comprising:

• transmitting, to a user equipment (UE), a plurality of transport blocks representing an application data unit;
• transmitting an indication to the UE that the UE is to provide feedback at an application data unit level;
• determining, based on a transmission from the UE or a lack of transmissions from the UE, application data unit level feedback for the application data unit, wherein the application data unit level feedback is based at least in part on a quantity of the plurality of transport blocks that were successfully decoded by the UE;
• and
• communicating with the UE in accordance with the application data unit level feedback.

An apparatus for wireless communications by a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a network node, a plurality of transport blocks representing an application data unit;
• receive an indication that the UE is to provide feedback at an application data unit level;
• determine application data unit level feedback for the plurality of transport blocks based at least in part on a quantity of the plurality of transport blocks that were successfully decoded by the UE;
• and
• indicate the application data unit level feedback to the network node.
