Question: What triggers the User Equipment (UE) to stop evaluating execution conditions during a Cell Handover (CHO) with candidate Secondary Cell Group (SCG)(s) in an E-UTRA and NR Multi-connectivity scenario?
Option 1: Receipt of a new Radio Resource Control (RRC) configuration message
Option 2: Completion of a predetermined timer set by the UE
Option 3: Either a Primary Cell (PCell) change or a Secondary Cell (PSCell) change is triggered
Option 4: Loss of signal from the current PCell
Explanation: According to multi-connectivity principles in E-UTRA and NR, during a CHO with candidate SCG(s), the UE assesses conditions for both new PCell and PSCell simultaneously. The evaluation process halts once the conditions for either a PCell change or a PSCell change are met, triggering the respective handover action. This ensures seamless connectivity while optimizing network resource utilization.
