Question: For a UTRA FDD UE supporting DC-HSDPA, what is the primary condition that must be met at the reference sensitivity level in terms of Block Error Ratio (BLER) performance?
Option 1: The BLER on each individual cell shall not exceed 10% for all Release versions.
Option 2: The BLER on each individual cell shall not exceed a specific value, applicable from Release 8 onwards.
Option 3: The overall network BLER is optimized to achieve maximum throughput at the reference sensitivity level.
Option 4: The UE ensures zero errors in data transmission when receiving at the reference sensitivity power level.
Explanation: This option correctly captures the essence of the reference sensitivity level requirement for UTRA FDD UEs supporting DC-HSDPA from Release 8 onwards, emphasizing a specific BLER threshold per cell, reflecting a nuanced understanding of telecom standards, focusing on signal quality metrics (BLER) at minimum receivable power levels, crucial for ensuring reliable data transmission in cellular networks.
