Question: For a UTRA FDD UE (Universal Terrestrial Radio Access, Frequency Division Duplexing User Equipment) supporting HSDPA (High Speed Downlink Packet Access), which of the following HSDPA UE capability categories are subject to the receiver single link performance requirements for HS-DSCH (High Speed Physical Downlink Shared Channel) as defined for Release 8 and later releases?
Option 1: Categories 21 - 24, excluding Dual band operation
Option 2: All categories supporting Dual band operation
Option 3: Categories 11 - 20, including Single band operation only
Option 4: Categories 25 and above, with or without Dual band operation
Explanation: This is correct because the question's context specifically mentions that the requirements apply to UTRA FDD UEs that support HSDPA UE capability categories 21 through 24, with the added condition of not supporting Dual band operation. This directly aligns with Option 1, making it the accurate choice based on the provided telecom domain knowledge and understanding of 3GPP specifications related to HSDPA and UE capabilities.
