Question: Upon receiving a sl-MeasIdToRemoveList from the network, what actions should a User Equipment (UE) take for each included sl-MeasId that matches an entry in its current VarMeasConfigSL configuration?
Option 1: Only remove the matching sl-MeasId entry from sl-MeasIdList within VarMeasConfigSL.
Option 2: Remove the sl-MeasId entry from sl-MeasIdList, remove related measurement reporting from VarMeasReportListSL (if present), and stop/reset the periodical reporting timer for that sl-MeasId.
Option 3: Ignore the request if any sl-MeasId in the list is not part of the current UE configuration, and do not take any action for matching IDs.
Option 4: Send an error message to the network for each non-matching sl-MeasId before processing valid ones.
Explanation: When a UE receives a list to remove sidelink measurement identities, it must update its configuration by removing the identified entry from the sidelink measurement ID list, eliminating associated reporting configurations, and halting/resetting the periodic reporting mechanism for that identity, ensuring synchronization with network instructions and efficient resource utilization.
