Question: In a 3GPP-defined test environment for UE conformance testing, with parameters set to default for a basic single cell E-UTRA setup, what is the expected state of the User Equipment (UE) at the start of a test case, assuming no additional specifications?
Option 1: Idle State (State 2), awaiting initial network connection
Option 2: Connected but not yet authenticated (State 3)
Option 3: DC MCG/SCG Dedicated Radio Bearer Established (State 5A)
Option 4: In a handover process between two cells (Transient State)
Explanation: According to the specified initial conditions for UE conformance testing in a basic single cell E-UTRA environment, the User Equipment is expected to be in an active state with dedicated resources allocated. Specifically, being in 'DC MCG/SCG Dedicated Radio Bearer Established (State 5A)' indicates that both Master Cell Group (MCG) and Secondary Cell Group (SCG) have established dedicated bearers for data transmission, signifying an advanced connected state suitable for various conformance tests requiring active network interaction. This state ensures the UE is ready to engage in detailed protocol and performance evaluations without the need for initial connection setup during each test case.
