Question: In 5G NR Base Station (BS) radio transmission and reception, what is the primary metric used to evaluate the performance of PUCCH format 3?
Option 1: Block Error Rate (BLER) at a specific Signal-to-Noise Ratio (SNR) threshold for data channels
Option 2: SNR required to achieve a UCI (Uplink Control Information) block error probability not exceeding 1%
Option 3: Peak Data Rate under full buffer traffic conditions for a single User Equipment (UE)
Option 4: Average Spectral Efficiency across all active bearers in a cell
Explanation: The correct answer reflects the specific performance metric for PUCCH format 3, focusing on the SNR needed to maintain a UCI block error probability below 1%, crucial for reliable uplink control signaling in 5G NR systems. The other options are incorrect as they pertain to data channels, peak throughput scenarios, or overall cell efficiency metrics, not directly relevant to PUCCH format 3's performance requirement.
