Question: For a UTRA FDD User Equipment (UE) supporting High Speed Downlink Packet Access (HSDPA), which of the following UE capability categories are subject to the MIMO performance requirements on the High Speed Physical Downlink Shared Channel (HS-DSCH) in multi-path fading environments, as per Release 10 and later releases?
Option 1: Categories 5 - 8
Option 2: Categories 9 - 12
Option 3: Categories 13 - 14
Option 4: Categories 15 - 18
Explanation: The correct answer is Option 4 because the MIMO performance requirements for HS-DSCH in multi-path fading environments apply to Release 10 and later releases for UTRA FDD UE supporting HSDPA with categories 15 through 18, indicating a direct association between these categories and the mentioned performance requirements under the specified conditions.
