Question: What is the minimum radio propagation condition that a System Simulator must support for both FDD (Frequency Division Duplex) and TDD (Time Division Duplex) modes in conformance testing for User Equipment (UE)?
Option 1: All defined propagation conditions for both FDD and TDD modes as specified in respective technical documents.
Option 2: Only the severe Propagation Condition for FDD mode, with optional support for TDD modes.
Option 3: At least one of the propagation conditions (either normal or severe) for either FDD or TDD mode.
Option 4: At least the normal Propagation Condition for both FDD and TDD modes, with other conditions being optional.
Explanation: A System Simulator is required to support at least the normal Propagation Condition for both FDD and TDD modes. This ensures baseline conformance testing capability across different radio environments, with flexibility to optionally support other propagation conditions based on specific test requirements.
