Question: In E-UTRAN Location Measurement Unit (LMU) performance tests involving parallel measurements with a specified number of UEs, how should interfering signals from additional UEs be modeled?
Option 1: As Co-Channel Interference (CCI) with variable power levels
Option 2: Using a mix of AWGN and fading channel models
Option 3: As Additive White Gaussian Noise (AWGN)
Option 4: By simulating Out-of-Band (OOB) emissions
Explanation: In E-UTRAN LMU performance testing, additional UEs beyond the specified number should be represented by Additive White Gaussian Noise (AWGN) to simulate the aggregate interference effect, simplifying the test environment while accounting for the overall noise floor impact.
