Question: For FDD UEs supporting HSDPA with capability categories 15 to 20, what is the assumed Type A reporting fraction for minimum performance requirements of CQI reporting under MIMO dual stream conditions?
Option 1: 100%
Option 2: 50%
Option 3: 25%
Option 4: Not Specified in Standards
Explanation: A 100% Type A reporting fraction implies that all subframes are utilized for CQI reporting, aligning with the stringent requirements for efficient MIMO operations in advanced HSDPA categories (15 to 20), ensuring optimal downlink transmission quality for reliable and high-performance connectivity.
