Question: For a UTRA FDD UE supporting HSDPA, which combination of Release and UE Capability Category is subject to receiver single link performance requirements for HS-DSCH in multi-path fading environments, assuming support for enhanced performance requirements type 3 but not DB-DC-HSDPA?
Option 1: Release 7 with UE Capability Category 12
Option 2: Release 8 with UE Capability Category 23
Option 3: Release 10 with UE Capability Category 20
Option 4: Release 6 with UE Capability Category 25
Explanation: According to specifications, Releases 8 and later (including Release 8) require UEs of categories 23-24, supporting enhanced performance requirements type 3 or 3i without DB-DC-HSDPA, to meet these performance requirements. This matches a Release 8 UE with Capability Category 23.
