Question: In a 5G NR network, when evaluating the absolute priority of a carrier frequency for cell reselection, what does the `CellReselectionSubPriority` value of `oDot4` correspond to in terms of fractional value addition to `cellReselectionPriority`?
Option 1: 0.1
Option 2: 0.3
Option 3: 0.5
Option 4: 0.4
Explanation: According to the specifications for `CellReselectionSubPriority`, each enumerated value directly corresponds to a specific fractional value (e.g., `oDot2` equals 0.2, `oDot4` equals 0.4). Therefore, when `CellReselectionSubPriority` is set to `oDot4`, it indicates that the fractional value of 0.4 should be added to `cellReselectionPriority` to determine the absolute priority for cell reselection in E-UTRA and NR networks.
