Question: In a TDD system, for a UE Category 25 from Release 8 onwards with MIMO capability, what determines the reporting accuracy of the Channel Quality Indicator (CQI) in AWGN and static orthogonal environments?
Option 1: Only the reporting variance of the CQI.
Option 2: Both the reporting variance and the BLER performance indicated by the reported CQI median transport format.
Option 3: The type of data streamed from the SS to the UE during measurement.
Option 4: The number of antennas in the MIMO configuration.
Explanation: The reporting accuracy of CQI depends on two key factors in AWGN and static orthogonal environments: the variability in reporting channel quality and how well the Block Error Rate performs as indicated by the median transport format chosen based on the reported CQI, ensuring both report precision and data transmission reliability are considered.
