Question: In a conformance testing scenario for User Equipment (UE) as per 3GPP specifications, with initial conditions set for V2X (Vehicle-to-Everything) testing, what is the expected configuration state of the UE at the start of the test?
Option 1: The UE shall be in Idle State with E-UTRA cell camping.
Option 2: The UE shall be in Out of Coverage, V2X setup state (State 5-V2X).
Option 3: The UE shall have an established LTE connection for data transmission.
Option 4: The UE shall be in a power-saving mode, awaiting network paging.
Explanation: For V2X conformance testing, the UE needs to be configured in a state that allows it to operate without relying on traditional cellular coverage for its V2X functionality. Being in an 'Out of Coverage' state with V2X setup enables the UE to operate under conditions where cellular network coverage is not guaranteed or necessary for the V2X service, crucial for safety-critical vehicular communications that must function regardless of cellular network availability.
