Let’s say UE RLC has sent packet from SN1 to SN6.
Let’s say SN5 has some issue.
UE has sent but eNB has not received the SN so it will send NACK.
So my question is:
- So if that SN is not able to ACK means RLC window will stall (will not move ahead)?
- Till how long UE will keep on sending SN5.
- What if SN5 is never received by eNB? Does that mean data is lost and no way to recover?
