  8. MPNC Slot Boundary Synchronization • If the Slot_drift is more than the guard time, the MPNC may choose either: • Shift slot boundary gradually toward reference device’s slot boundary by transmitting beacon frame earlier or later in steps less than guard time. • Use procedure 8.10.1 of [R1] to move beacon transmission earlier or later to align slot boundary to reference device’s slot boundary in NbrOfChangeBeacons superframes.
