Question: Upon receiving a sl-MeasIdToAddModList with an existing sl-MeasId, what action does the UE take regarding the corresponding entry in the VarMeasConfigSL?
Option 1: Replace the existing entry with the newly received value for this sl-MeasId.
Option 2: Add a new entry for this sl-MeasId without altering the existing one.
Option 3: Remove the existing entry from the VarMeasConfigSL without adding a new one.
Option 4: Suspend updates for this sl-MeasId until further instruction.
Explanation: When the User Equipment (UE) receives an updated list containing an existing Sidelink Measurement Identity, it updates its internal configuration by replacing the old entry with the new information received for that specific sl-MeasId. This ensures the UE's measurement configurations are up-to-date and aligned with the network's latest instructions, crucial for efficient sidelink communication management.
