sending a first acknowledgement to the second sink device indicating the first sink device successfully received the packet;
determining, via eavesdropping on the second communication link, the second sink device transmitted a second acknowledgement to the source device indicating the second sink device successfully received the packet;
receiving, via eavesdropping on the second communication link, a retransmission of the packet transmitted by the source device; and
sending a third acknowledgement to the source device indicating the second sink device successfully received the packet.
