Question: What is a prerequisite for a User Equipment (UE) to support directMCG-SCellActivationResume-r16, in terms of another capability it must also indicate support for?
Option 1: resumeWithMCG-SCellConfig-r16
Option 2: eNB-CBRI-Support-r12
Option 3: CA-BandwidthClassDL-A-r10
Option 4: PDCP-Parameters-r9
Explanation: If a UE indicates support for directMCG-SCellActivationResume-r16, it must also indicate support for resumeWithMCG-SCellConfig-r16. This ensures the UE can properly handle MCG SCell configuration and resumption in activated state during RRC connection resume procedures.
