What is the reason for eNB to receive more DTX than NACK/ACK ?

Question

While UE in CDRX and eNB receive NACK instead of ACK from UE. After UE sends HARQ feedback UE is not expecting an Retransmission and moved to DRX OFF. But eNB is retranmitting it, How UE handles this?

Answer 1

Hi Poonam,

If eNB is receiving more DTX than NAC then it is an poorest channel condition or UE is transmitting in different location or SF.

If UE is in poor channel condition even though it transmit eNB cannot decode or able to see the data in RB. If UE is misconfigured then eNB cannot receive the data.
