Question: For a UTRA FDD UE supporting dual-band single uplink 4C-HSDPA, what is the primary purpose of evaluating its blocking characteristic for HS-DSCH categories 29 to 32?
Option 1: To assess the UE's ability to amplify weak signals in the presence of strong adjacent channel signals.
Option 2: To measure the UE's capacity to handle simultaneous uplink and downlink transmissions on different frequency bands.
Option 3: To determine the UE's resistance to overheating when multiple frequency bands are activated.
Option 4: To evaluate the receiver's performance in receiving a wanted signal without degradation from unwanted interferers on non-adjacent, non-spurious response frequencies.
Explanation: The blocking characteristic is crucial for understanding how well a UE can maintain its reception quality of a desired signal when there are other, unwanted signals present on the frequency spectrum, excluding those immediately adjacent or causing spurious responses. This directly impacts the UE's ability to reliably receive data in crowded or noisy radio environments, which is essential for maintaining service quality, especially for advanced categories like 29 to 32 that likely involve higher data rates and more complex signal processing.
