Event A6

Technical Explanation

In Carrier Aggregation, Event A6 manages SCell mobility. It fires when a neighboring cell on the SCell frequency becomes an offset better than the active serving SCell. The gNodeB uses this to swap the secondary carrier to the stronger neighbor cell without affecting the primary PCell anchor.

Key Functions

• Governs Secondary Cell (SCell) mobility in Carrier Aggregation
• Fires when SCell neighbor outperforms active SCell by configured offset
• Enables seamless SCell replacement without disrupting primary PCell connection
