Question: In a conformance testing setup for User Equipment (UE) as per 3GPP specifications, what characterizes BOTH the downlink and uplink connections between the System Simulator and the UE under Normal propagation conditions?
Option 1: Presence of Additive White Gaussian Noise (AWGN) with fading effects.
Option 2: Absence of multipath effects but presence of AWGN.
Option 3: Presence of fading effects without AWGN or multipath effects.
Option 4: Absence of both Additive White Gaussian Noise (AWGN) and fading/multipath effects.
Explanation: Under Normal propagation conditions in UE conformance testing, both the downlink from the System Simulator to the UE and the uplink from the UE to the System Simulator are ideally set up without the complexities of real-world signal degradation. This means neither AWGN (which affects signal quality by adding random noise) nor fading/multipath effects (which cause signal distortion due to environmental factors) are introduced, ensuring a controlled test environment. Thus, the correct answer reflects the absence of these distortions in both directions.
