Question: In a TDD (Time Division Duplex) measurement setup, what parameters are considered by the Base Station to calculate the Block Error Ratio (BLER), which can then be mapped to throughput for a fixed reference channel?
Option 1: Number of ACKs, Total Transmission Time, and Scheduled DTX-TTIs (regDTX)
Option 2: Number of NACKs, Number of ACKs, and Statistical DTX-TTIs (statDTX) occurrences
Option 3: Number of NACKs, Number of ACKs, and the impact of Statistical DTX-TTIs (with Scheduled DTX-TTIs implicitly accounted for)
Option 4: Total Payload Bits Sent, Received Signal Strength, and All Types of DTX-TTIs
Explanation: The correct BLER calculation involves the ratio of (NACK + statDTX) to (NACK + statDTX + ACK), considering only statistical DTX-TTIs alongside NACKs and ACKs, as Scheduled DTX-TTIs are implicitly accounted for in the test setup.
