Question: During an IAB-node orderly release, what is the correct sequence of actions if both the F1 interface and IAB-MT need to be released?
Option 1: Release the collocated IAB-MT first, then remove the F1 interface connection to the IAB-DU.
Option 2: Remove the F1 interface connection to the IAB-DU before releasing the collocated IAB-MT.
Option 3: Simultaneously release the IAB-MT and remove the F1 interface connection to the IAB-DU.
Option 4: Release the IAB-MT without removing the F1 interface connection, as it is automatically removed afterwards.
Explanation: This sequence ensures a structured release process. Removing the F1 interface first isolates the IAB-DU from further network interactions, and then releasing the collocated IAB-MT finalizes the node's disconnection, preventing potential conflicts or data inconsistencies in the network. This approach aligns with efficient resource management and network stability principles in telecom networks.
