1. An apparatus comprising:
a memory; and
circuitry of a broadcaster coupled with the memory to:
cause transmission of an audio protocol data unit (PDU) during each of one or more subevents;
generate a feedback request frame as a feedback request PDU;
cause transmission of the feedback request PDU on a feedback channel;
scan the feedback channel for one or more feedback response PDUs transmitted in response to transmission of the feedback request PDU; and
modify one or more parameters of transmission of the audio PDUs in a subsequent broadcast isochronous group (BIG) event based on the one or more feedback response PDUs.
 
9. A non-transitory computer-readable medium, comprising instructions, which when executed by a processor, cause the processor to perform operations to:
cause transmission of an audio protocol data unit (PDU) during each of one or more subevents;
generate a feedback request frame as a feedback request PDU;
cause transmission of the feedback request PDU on a feedback channel;
scan the feedback channel for one or more feedback response PDUs transmitted in response to transmission of the feedback request PDU; and
modify one or more parameters of transmission of the audio PDUs in a subsequent broadcast isochronous group (BIG) event based on the one or more feedback response PDUs.
 
16. An apparatus comprising:
a memory; and
circuitry of a receiver coupled with the memory to:
receive of an audio protocol data unit (PDU) during each of one or more subevents;
receive a feedback request PDU on a feedback channel;
generate a feedback response PDU in response to transmission of the feedback request PDU; and
cause transmission of the feedback response PDU on the feedback channel.
 
22. A non-transitory computer-readable medium, comprising instructions, which when executed by a processor, cause the processor to perform operations to:
receive of an audio protocol data unit (PDU) during each of one or more subevents;
receive a feedback request PDU on a feedback channel;
generate a feedback response PDU in response to transmission of the feedback request PDU; and
cause transmission of the feedback response PDU on the feedback channel.
