Question: What action does the UE take when it receives an LTM-Config IE with ltm-ReferenceConfiguration set to setup and the current VarLTM-Config already includes an ltm-ReferenceConfiguration?
Option 1: The UE replaces the ltm-ReferenceConfiguration value within VarLTM-Config with the received ltm-ReferenceConfiguration.
Option 2: The UE stores the received ltm-ReferenceConfiguration in a new VarLTM-Config.
Option 3: The UE removes the existing ltm-ReferenceConfiguration from VarLTM-Config.
Option 4: The UE ignores the received ltm-ReferenceConfiguration.
Explanation: According to the LTM configuration procedure, when the UE receives an LTM-Config IE with ltm-ReferenceConfiguration set to setup and the current VarLTM-Config already includes an ltm-ReferenceConfiguration, it replaces the existing value within VarLTM-Config with the received one. This ensures that the UE updates its internal state with the new configuration information.
