Question: In a Missed ACK test for a UE on an E-DPDCH with E-DPCCH, what does a retransmission indicated by the UE typically signify to the higher layers?
Option 1: Successful receipt of an ACK from the network side
Option 2: Receipt of a NACK or DTX interpreted as a NACK by the UE
Option 3: An increase in the Nominal Average Information Bit Rate in the Downlink
Option 4: A change in the UL datarate configuration on the E-AGCH
Explanation: A retransmission indicated by the UE signifies that it interpreted the previous response as either a NACK or DTX, treated as a NACK by higher layers, prompting the retransmission, highlighting the importance of accurate acknowledgement interpretation in maintaining reliable data transfer over wireless communications.
