PX Deq: Signal ACK RSG

PX Deq: Signal ACK RSG wait event does not have much information available even on My Oracle Support portal. I was not able to find much information about this. I noticed this wait event at the top of wait events in my AWR report as can be seen bellow that made me do some investigation. First and the foremost, this wait event is related to parallel execution of SQLs.
