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 receiver single link performance testing for the High Speed Physical Downlink Shared Channel (HS-DSCH)?
Option 1: Applies to all UE categories, regardless of HSDPA support, from Release 5 onwards.
Option 2: Applies only to UEs with HSDPA capability categories 7 and above, from Release 6 onwards.
Option 3: Applies to all types of UTRA for FDD UEs supporting HSDPA UE capability categories 1 to 6, but only from Release 7 onwards.
Option 4: Applies to all types of UTRA for the FDD UE that support HSDPA UE capability categories 1 to 6 and the optional enhanced performance requirements type 1, from Release 6 and later releases.
Explanation: This is correct because the question's conditions (applicability to all types of UTRA for FDD UEs, specific HSDPA UE capability categories 1 to 6, and the mention of optional enhanced performance requirements type 1) directly match the provided context. The specification clearly states that these requirements apply from Release 6 onwards, making Option 4 the accurate choice.
