Question: For a UTRA FDD User Equipment (UE) supporting High Speed Downlink Packet Access (HSDPA), which of the following statements is true regarding the applicability of MIMO performance requirements for the High Speed Physical Downlink Shared Channel (HS-DSCH) in multi-path fading environments?
Option 1: Applies to all UTRA FDD UE, regardless of HSDPA support, starting from Release 6.
Option 2: Applies only to Dual band operation-capable UEs with HSDPA, starting from Release 9.
Option 3: Applies to all UEs supporting HSDPA, irrespective of the UE category, starting from Release 5.
Option 4: Applies specifically to UTRA FDD UEs that support HSDPA UE capability categories 25-28, but do not support Dual band operation, starting from Release 9.
Explanation: This is correct because the MIMO performance requirements for HS-DSCH in multi-path fading environments are specifically tailored for UEs with certain capabilities (HSDPA UE capability categories 25-28) and limitations (not supporting Dual band operation), ensuring optimal performance within defined parameters, starting from Release 9.
