Question: What is the primary purpose of the "Time duration of Scheduled IP Throughput in UL" measurement in E-UTRAN?
Option 1: To measure the time taken to transmit a data burst including the last piece of data transmitted in the TTI when the buffer is emptied in uplink.
Option 2: To calculate the throughput of packet switched traffic between eNodeB and RNs.
Option 3: To determine the number of QCIs supported by an eNodeB.
Option 4: To provide the time duration to transmit a data burst excluding the last piece of data transmitted in the TTI when the buffer is emptied in uplink, for supporting the Integrity KPI "E-UTRAN IP Throughput".
Explanation: The correct answer is Option 4 because the primary purpose of this measurement is to provide the time duration to transmit a data burst excluding the last piece of data transmitted in the TTI when the buffer is emptied in uplink, which supports the Integrity KPI "E-UTRAN IP Throughput" as mentioned in the text.
