Question: For a UTRA FDD User Equipment (UE) supporting single band 4C-HSDPA, what is the primary purpose of measuring Spurious Response as defined in the context of radio transmission and reception?
Option 1: To evaluate the UE's ability to transmit signals without interfering with adjacent channels.
Option 2: To assess the UE's receiver sensitivity in the presence of multiple desired signals.
Option 3: To determine the UE's maximum output power for a given channel bandwidth.
Option 4: To gauge the UE's receiver performance when a wanted signal is affected by an unwanted Continuous Wave (CW) interfering signal.
Explanation: Measuring Spurious Response is crucial for understanding how well a UE's receiver can maintain its performance when receiving a desired signal on its assigned channel frequency, while being subjected to an unwanted CW interfering signal at another frequency. This directly relates to the UE's ability to handle interference, ensuring reliable communication in shared or adjacent spectrum environments.
