Question: In E-UTRA conformance testing, what is the primary distinction of a 'Virtual Cell Configuration' when compared to other SS cell configurations for User Equipment (UE)?
Option 1: It is exclusively used for Primary Cells (PCells) in Carrier Aggregation scenarios.
Option 2: It is specifically designed for Secondary Cells (SCells) that are not active.
Option 3: It is a mandatory configuration for all cells in non-Carrier Aggregation test cases.
Option 4: It combines elements of full cell and broadcast-only configurations for enhanced testing.
Explanation: The virtual cell configuration is uniquely identified by its application to Secondary Cells (SCells) that are not active, distinguishing it from other configurations. This highlights its specialized role in testing inactive SCells, ensuring comprehensive coverage of UE behavior under various network conditions.
