Question: What action does an N3C relay UE take when `n3c-IndirectPathConfigRelay` is set to "setup" and both `n3c-MappingToReleaseList` and `n3c-MappingToAddModList` are included in the configuration?
Option 1: Perform both N3C bearer mapping release (as per 5.3.5.17.3.4.1) and addition/modification (as per 5.3.5.17.3.4.2) sequentially.
Option 2: Only perform N3C bearer mapping release, ignoring the addition/modification list when a release list is present.
Option 3: Ignore both lists if they are included together to avoid configuration conflicts.
Option 4: Request further configuration clarification from the network before proceeding.
Explanation: When `n3c-IndirectPathConfigRelay` is set to "setup", the N3C relay UE is instructed to manage its bearer mappings based on the included lists. The presence of both `n3c-MappingToReleaseList` and `n3c-MappingToAddModList` indicates that the UE should perform two separate actions: release existing mappings (as specified in 5.3.5.17.3.4.1) and add/modify new mappings (as per 5.3.5.17.3.4.2). These actions are sequential, ensuring the UE's configuration is updated accurately without conflicts.
