Question: What is the primary objective of testing Intermodulation (IM) in a scenario where multiple User Equipments (UEs) are transmitting in close proximity to each other?
Option 1: To ensure that the aggregate transmit power of adjacent UEs does not exceed a specified threshold, thereby preventing interference to nearby Base Stations (BS).
Option 2: To verify that Intermodulation Products (IMPs) generated by closely located UEs do not fall within the receive band of other UEs or BS, thus minimizing unwanted interfering signals.
Option 3: To evaluate the impact of IM on the uplink transmission quality of a single UE in a multi-user environment, focusing solely on the affected UE's performance metrics.
Option 4: To determine the minimum spatial separation required between UEs to eliminate the effects of intermodulation on the downlink reception quality.
Explanation: The correct answer aligns with the test purpose, aiming to limit interferences to both the own system (UE) and other systems (including BS) due to Intermodulation Products, preventing unwanted signals from affecting reception bands across different devices/systems in close vicinity.
