Question: What is the duration represented by the unit of H-SFN for the values of periodicity and offset in PUR-PeriodicityAndOffset-NB information element?
Option 1: 10.24 seconds
Option 2: 1 second
Option 3: 1 millisecond
Option 4: 1 minute
Explanation: In the context of Radio Resource Control for cellular networks, H-SFN duration is a key timing reference. For PUR-PeriodicityAndOffset-NB, both periodicity and offset values are defined in units of H-SFN, which equals 10.24 seconds, crucial for coordinating radio resources efficiently.
