What makes ARQ in RLC layer more reliable than HARQ in the Physical Layer? How does the sequence numbering in RLC help to increase the reliability?

ARQ is used along with HARQ so that it improves the reliability of the data along with the speed of correction of HARQ. How does it do that?

Does the Status PDU in an RLC give a NACK only for a failed reception or for an erroneous reception as well?

The HARQ process gives a NACK for an erroneous reception so that it can correct it. What about the ARQ process? Some literature talks about only failed reception, while some talk about erroneous...

Why do we need two separate retransmissions in RLC and MAC layer of the LTE Protocol stack? Is it possible to combine both into one in the revised 5G?

The Acknowledge mode of the RLC layer has a ARQ mechanism for better data reliability, while we have hybrid ARQ mechanism in the physical layer. The data traverses the path through all layers,...
