Question: When `deriveSSB-IndexFromCellInter-r17` is enabled for an ATG UE, what is the maximum tolerance for frame boundary alignment across cells on the target carrier and reference cell?
Option 1: 1 SSB symbol of the target carrier
Option 2: 1 PDSCH symbol of the target carrier
Option 3: The duration of one subframe in the reference cell
Option 4: Minimum of (2 SSB symbols of the target carrier, 1 PDSCH symbol of the reference cell)
Explanation: This option is correct because when `deriveSSB-IndexFromCellInter-r17` is enabled, frame boundary alignment across cells on the target carrier and the reference cell must be within a tolerance not worse than the minimum of two specific values: 2 SSB symbols of the target carrier or 1 PDSCH symbol of the reference cell, ensuring synchronization accuracy for proper radio resource management.
