Question: In E-UTRA, what is the primary purpose of the `resumeWithMCG-SCellConfig-r16` parameter in relation to a UE's radio access capabilities?
Option 1: To indicate UE support for handover between different E-UTRAN frequencies.
Option 2: To signal UE capability for simultaneous transmission on multiple bands.
Option 3: To determine the maximum number of SCells a UE can support in CA (Carrier Aggregation).
Option 4: To define whether a UE supports (re-)configuration of MCG (Master Cell Group) SCells via the RRCConnectionResume message.
Explanation: This parameter is directly linked to the (re-)configuration of MCG SCells through the RRCConnectionResume message, highlighting its role in efficient session management and resource allocation upon connection resumption.
