Question: For a User Equipment (UE) supporting High-Speed Downlink Packet Access (HSDPA) in a Frequency Division Duplexing (FDD) Ultra Mobile Terrestrial Radio Access Network (UTRA), which of the following statements accurately describes the applicability of reporting accuracy requirements for the Channel Quality Indicator (CQI) under fading environments?
Option 1: Applies to all UTRA FDD UEs with HSDPA capability categories, regardless of release.
Option 2: Applies only to Release 8 and later releases for UTRA FDD UEs supporting HSDPA UE capability categories 1-12.
Option 3: Varies by UE category but is consistent across all FDD modes in the same release.
Option 4: Depends on the UE's HSDPA capability category, with different release requirements for categories 1-12 versus 13-20.
Explanation: The correct answer reflects that CQI reporting accuracy under fading environments depends on the UE's HSDPA capability category, with a differentiation in release requirements based on device capabilities and specific releases of standards.
