Question: Upon receiving an ltm-CSI-ResourceConfigToAddModList from the network, how should a User Equipment (UE) handle an existing ltm-CSI-ResourceConfigId that is already present in its current VarLTM-Config?
Option 1: Ignore the received configuration and maintain the existing setup for that ltm-CSI-ResourceConfigId.
Option 2: Replace the existing LTM-CSI-ResourceConfig within VarLTM-Config with the newly received one for that ltm-CSI-ResourceConfigId.
Option 3: Add the new configuration to VarLTM-Config in addition to the existing one, allowing for duplicate ltm-CSI-ResourceConfigId entries.
Option 4: Delete the existing LTM-CSI-ResourceConfig from VarLTM-Config without adding the new one.
Explanation: This action ensures that the UE's configuration remains up-to-date with the network's instructions. By replacing the existing LTM-CSI-ResourceConfig, the UE maintains a singular, current configuration for each ltm-CSI-ResourceConfigId, which is crucial for efficient and accurate CSI (Channel State Information) reporting in 5G NR (New Radio) networks. This process supports optimal radio resource management and utilization.
