Question: For a UTRA FDD UE supporting HSDPA, which UE capability categories are subject to receiver open loop transmit diversity performance requirements for HS-DSCH in multi-path fading environments?
Option 1: Categories 7 - 10 (excluding optional enhanced performance requirements Type 3 or Type 3i)
Option 2: Categories 13 and 14 (applicable from Release 5 onwards)
Option 3: All categories supporting HSDPA (including Type 3, Type 3i enhanced performance)
Option 4: Only Categories 1 - 6 (for basic HSDPA functionality)
Explanation: According to the specifications, for Release 6 and later releases, these requirements apply specifically to UTRA FDD UE supporting HSDPA in categories 7 - 10, excluding optional Type 3 or Type 3i enhanced performance. This ensures these categories meet necessary receiver open loop transmit diversity performance standards for HS-DSCH in multi-path fading environments.
