Question: For a UE supporting HSDPA with capability categories 16-18, in a TDD mode from Release 8 onwards, what determines the reporting accuracy of the Channel Quality Indicator (CQI) under AWGN environments?
Option 1: Reporting variance and BLER performance using the transport format indicated by the reported CQI median.
Option 2: Only the Signal-to-Noise Ratio (SNR) of the received signal at the UE.
Option 3: The type of data streamed from the SS to the UE, influencing the CQI measurement.
Option 4: The UE's capability category alone, with higher categories ensuring higher accuracy.
Explanation: The reporting accuracy of the Channel Quality Indicator (CQI) under AWGN environments is determined by two key factors: the reporting variance and the BLER performance as indicated by the transport format suggested by the reported CQI median, reflecting both consistency and effectiveness of CQI reporting for optimal communication quality in wireless networks.
