Question: For a FDD UE supporting UL CLTD and HSDPA, what is the primary factor determining its nominal maximum output power tolerance?
Option 1: Type of UTRA (Universal Terrestrial Radio Access) mode supported
Option 2: The bandwidth of the transmitted signal relative to the chip rate
Option 3: The release version of the UE's software (e.g., Release 11 vs. later releases)
Option 4: The Power Class of the User Equipment (UE)
Explanation: According to specifications, the nominal maximum output power with UL CLTD and its tolerance are directly defined by the Power Class of the UE, standardizing maximum transmit power levels for interoperability and managing interference within cellular networks.
