Question: In 3GPP-compliant HSDPA testing for enhanced performance requirements type 1 with UE receiver diversity, what is the specified relationship between the fading profiles used in multiple faders?
Option 1: Correlated to each other to simulate real-world signal dependency
Option 2: Uncorrelated to each other to ensure diverse signal scenario testing
Option 3: Partially correlated to account for environmental factors
Option 4: Determined by the UE's receiver diversity algorithm
Explanation: To comprehensively test the enhanced performance of HSDPA with UE receiver diversity, using uncorrelated fading profiles in multiple faders ensures that the testing covers a wide range of signal scenarios, mimicking the unpredictability of real-world wireless communication environments. This approach helps in validating the device's ability to handle diverse signal conditions effectively, which is crucial for reliable and high-performance wireless communications.
