ACK for 802.11 broadcast frame?

Question

On 802.11 if I send a unicast frame, receiver will acknowledge by sending an ACK frame. But what about a broadcast frame? For example, A want to send a broadcast frame. A sends it to AP, AP acknowledges. Then AP broadcasts the frame. Does the AP listen for ACKs?

What about 802.3 Ethernet? Does Ethernet broadcasts ask for ACKs?

Thanks!

Answer 1

No, the AP will not listen for acks when it broadcasts your (broadcast) frame. And no, 802.3 Ethernet does not ack broadcasts either.

Answer 2

No. For broadcast data/frame AP won't expect and listen acks. In 802.3 Ethernet also it doesn't give ack for broadcast frame
