Question: For a UE supporting HSDPA with MIMO dual stream, what is the assumed reporting fraction for Type A CQI reporting in minimum performance requirements?
Option 1: 50% of N_cqi_typeA and variable M_cqi
Option 2: 100% with both N_cqi_typeA and M_cqi set to 1
Option 3: Dynamic adjustment based on propagation conditions
Option 4: Not defined for MIMO dual stream conditions
Explanation: This is correct because the minimum performance requirements for CQI reporting under MIMO dual stream conditions assume a Type A reporting fraction of 100%, with both N_cqi_typeA and M_cqi set to their maximum effectiveness (value of 1), ensuring comprehensive feedback for optimal downlink transmission in multi-antenna scenarios.
