Question: What action does the IAB-node take for each BH-RLC-ChannelID value included in the bh-RLC-ChannelToReleaseList as part of the current IAB-node configuration within the same cell group?
Option 1: The IAB-node releases the RLC entity or entities and the corresponding logical channel.
Option 2: The IAB-node only releases the RLC entity or entities.
Option 3: The IAB-node only releases the corresponding logical channel.
Option 4: The IAB-node does not take any action.
Explanation: According to the specification, for each BH-RLC-ChannelID value included in the bh-RLC-ChannelToReleaseList as part of the current IAB-node configuration within the same cell group (LCH release), the IAB-node releases both the RLC entity or entities and the corresponding logical channel. This is specified in TS 38.322, clause 5.1.3.
