Question: What is excluded from the 'Total Number of UL TBs' performance measurement in a cell?
Option 1: HARQ (Hybrid Automatic Repeat Request) retransmissions
Option 2: CRC (Cyclic Redundancy Check) failures
Option 3: Packet Switched Traffic Errors
Option 4: Uplink Transmission Delays
Explanation: The correct answer is Option 1 because HARQ retransmissions are excluded from this measurement, crucial for accurately assessing the initial transmission success rate without the skew of retransmitted packets.
