Question: A UE signals `crs-InterfMitigationTM1toTM9-r13 = 3` to the network. What is the maximum downlink Component Carrier (CC) Aggregation (CA) configuration where this UE may apply Cell-Specific Reference Signal (CRS) Interference Mitigation (IM)?
Option 1: Non-CA only
Option 2: Up to 2DL CA configurations
Option 3: Up to 3DL CA configurations, including non-CA and 2DL CA
Option 4: Any CA configuration beyond 4DL
Explanation: When a UE sets `crs-InterfMitigationTM1toTM9-r13` to a specific value (in this case, 3), it indicates the maximum downlink CC CA configuration where the UE may apply CRS IM. A value of '3' signifies support for CRS-IM on at least one downlink CC for supported non-CA, 2DL CA, and up to 3DL CA configurations, ensuring the network is aware of the UE's capabilities for mitigating interference in various aggregation scenarios.
