Question: For a UE (User Equipment) supporting dual band 4C-HSDPA with HS-DSCH categories 29 to 32, what is the primary condition that must be met at the reference sensitivity level (<REFSENS>) for each individual cell in FDD mode?
Option 1: The UE must achieve a minimum data throughput of 100 Mbps.
Option 2: The Signal-to-Noise Ratio (SNR) at the antenna port must exceed a threshold of 10 dB.
Option 3: The Block Error Ratio (BLER) on each individual cell shall not exceed a specific value.
Option 4: The UE's transmission power must be reduced to its minimum capable level.
Explanation: This question assesses understanding of the reference sensitivity level (<REFSENS>) in the context of FDD UEs supporting dual band 4C-HSDPA. The correct answer, Option 3, highlights the key performance indicator (KPI) for <REFSENS>, which is maintaining a Block Error Ratio (BLER) below a specified threshold on each cell. This ensures reliable data transmission under minimum receive power conditions. Options 1 and 2 are incorrect as they introduce unrelated metrics (throughput and SNR), while Option 4 misinterprets the concept by focusing on transmission power rather than reception sensitivity.
