Is it possible to send NACK in PHICH and new DCI with NDI toggled?

+1 vote

This case will UE accept it as NEW transmission or will it resend the TB?

answer Mar 15, 2019 by Sushant Bose
But NDI is toggled right then how UE will resend the TB?
Correct, NDI toggled it will be new transmission for UE but "f UE sends nack in UL in PHICH, dl wont send NDI = 1"
One more comment here, to consider it for new transmission the RV has to be 0, but in this case it will not be. please update if i am wrong, answers most welcome
I am sorry, i was wrong .DCI has more priority than PHICH, so If NDI is toggled in DCI-0 then PHICH feedbacks are dont care. NDI takes precedence. So UE will do New transmission.
