Question: For MIMO single stream conditions in FDD UEs, what is the assumed ratio of CQI Type A to Type B reporting for defining minimum performance requirements of channel quality indicator (CQI) reporting?
Option 1: 2:1
Option 2: 1:2
Option 3: 1:1
Option 4: 3:1
Explanation: The correct answer is based on the standard's definition for minimum performance requirements under MIMO single stream conditions, where the parameters N_cqi_typeA and M_cqi are set to achieve a CQI Type A versus Type B reporting ratio of 1/2. This specific ratio is crucial for evaluating the reporting accuracy of CQI in relation to the Block Error Rate (BLER) performance for transport formats indicated by reported CQI medians. Understanding this ratio is essential for assessing the efficiency and reliability of channel quality feedback in enhancing the overall network's adaptive transmission strategies, particularly in scenarios involving Multiple Input Multiple Output (MIMO) single stream transmissions.
