Question: Upon receiving a new `quantityConfig` from the network, what action does the User Equipment (UE) take regarding each `measId` included in the `measIdList` within `VarMeasConfig`?
Option 1: The UE updates the measurement reporting entry for this `measId` in the `VarMeasReportList` with new parameters.
Option 2: The UE initiates the periodical reporting timer or timer T321 for this `measId`, if not already running.
Option 3: The UE keeps the current measurement configuration unchanged for this `measId`.
Option 4: The UE removes the measurement reporting entry for this `measId` from the `VarMeasReportList` (if included), stops and resets the associated timer (T321 or periodical reporting timer).
Explanation: This action is in line with efficient resource management and updating of measurement configurations. By removing the entry, stopping, and resetting the timer for each affected `measId`, the UE ensures it no longer reports outdated measurements, aligning with the newly received quantity configuration from the network. This approach minimizes unnecessary signaling and optimizes the UE's reporting based on the latest network instructions.
