Question: For a UTRA FDD UE (User Equipment) supporting dual band dual uplink 4C-HSDPA and HS-DSCH categories 29 to 32, what is the primary purpose of evaluating its blocking characteristic?
Option 1: To assess the transmitter's ability to handle multiple frequency bands simultaneously.
Option 2: To measure the receiver's sensitivity to its own spurious emissions.
Option 3: To determine the receiver's capability to maintain performance in the presence of unwanted interferers on non-adjacent channels.
Option 4: To test the UE's handover functionality between different frequency bands.
Explanation: The blocking characteristic is crucial for understanding how well a receiver can filter out unwanted signals (interferers) that are not on adjacent channels or spurious response frequencies, ensuring the desired signal's quality is maintained. This directly impacts the UE's ability to receive and process the intended signal effectively in crowded spectral environments, which is vital for reliable communication in modern telecom networks.
