Question: For a UE (User Equipment) supporting HSDPA with MIMO dual stream conditions, what is the assumed reporting fraction for Type A channel quality indicator (CQI) reporting in determining minimum performance requirements?
Option 1: 50% of N_cqi_typeA and variable M_cqi
Option 2: 100% of N_cqi_typeA with M_cqi set to 1
Option 3: Variable N_cqi_typeA with M_cqi set to a minimum of 2
Option 4: 25% of maximum possible N_cqi_typeA and M_cqi values
Explanation: The correct answer is based on the standard's specification for minimum performance requirements under MIMO dual stream conditions, which assumes a Type A reporting fraction of 100%. This means both N_cqi_typeA and M_cqi are set to maximize the reporting rate, hence both are effectively utilized to indicate the highest reporting fraction for Type A, ensuring thorough testing of the UE's ability to report accurate channel quality under dual stream transmissions.
