Question: Upon expiry of timer T320, how does a User Equipment (UE) handle cell reselection priority information in a 5G NR network?
Option 1: The UE retains stored cell reselection priority information and combines it with newly broadcast system information.
Option 2: The UE continues to apply the previously inherited cell reselection priorities from another Radio Access Technology (RAT).
Option 3: The UE discards any stored or inherited cell reselection priority information and applies only what is currently broadcast in the system information.
Option 4: The UE ignores the expiry of T320 and maintains its current cell reselection behavior without updating priorities.
Explanation: Upon T320 expiry, to ensure alignment with the latest network preferences, the UE must discard any stored or inherited cell reselection priority information. This prevents outdated preferences from influencing reselection decisions. By applying only the currently broadcast system information, the UE ensures it follows the most up-to-date cell reselection priorities set by the network, optimizing its connectivity and resource utilization within the 5G NR environment.
