Feedback mechanism in integrated access fronthaul multi-hop networks

An apparatus for wireless communication at a first radio unit (RU), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a control unit, a configuration for relaying or repeating data received from a second RU to a receiving unit;
• determine whether first feedback associated with the data is received from the second RU;
• and
• transmit second feedback to at least one of the receiving unit or the control unit, the second feedback including first information indicating at least one of the first feedback or whether the first feedback was received.

An apparatus for wireless communication at a first radio unit (RU), comprising:

• means for receiving, from a control unit, a configuration for relaying or repeating data received from a second RU to a receiving unit;
• means for determining whether first feedback associated with the data is received from the second RU;
• and
• means for transmitting second feedback to at least one of the receiving unit or the control unit, the second feedback including first information indicating at least one of the first feedback or whether the first feedback was received.

A computer-readable medium of a first radio unit (RU) storing computer executable code, the code when executed by a processor causes the processor to:

• receive, from a control unit, a configuration for relaying or repeating data received from a second RU to a receiving unit;
• determine whether first feedback associated with the data is received from the second RU;
• and
• transmit second feedback to at least one of the receiving unit or the control unit, the second feedback including first information indicating at least one of the first feedback or whether the first feedback was received.
