Question: For a UTRA FDD User Equipment (UE) supporting HSDPA, which UE capability categories are subject to receiver single link performance requirements for HS-DSCH in multi-path fading environments?
Option 1: Categories 1 - 5
Option 2: Categories 7 - 10 (and optional enhanced performance types 2, 3, or 3i)
Option 3: Categories 11 - 12
Option 4: Categories 15 and above
Explanation: According to specifications, receiver single link performance requirements for HS-DSCH in multi-path fading environments apply to UTRA FDD UEs supporting HSDPA in categories 7-10, and those with optional enhanced performance types 2, 3, or 3i, focusing on robust downlink shared channel performance for high-speed data throughput.
