Question: In a cellular network using FDD, when evaluating block error rates (BLER) based on cell-specific Median Channel Quality Indicator (CQI), what are the expected BLER values for blocks associated with composite CQI reports of cell-specific Median CQI and Median CQI+3 respectively?
Option 1: 60% for Median CQI, 15% for Median CQI+3
Option 2: 15% for Median CQI, 60% for Median CQI+3
Option 3: 50% for both Median CQI and Median CQI+3
Option 4: 20% for Median CQI, 30% for Median CQI+3
Explanation: A higher CQI value (e.g., Median CQI+3) indicates better channel conditions, resulting in a lower Block Error Rate (BLER). Conversely, a lower CQI value (e.g., Median CQI) suggests poorer conditions, leading to a higher BLER. Thus, the correct answer reflects the expected outcome where blocks transmitted under better channel conditions have a significantly lower BLER (15%) compared to those under average conditions with a higher BLER (60%).
