21 DL Interference Mitigation (FDD only)

25.3003GPPGeneral descriptionRelease 17Stage 2TSUniversal Terrestrial Radio Access Network (UTRAN)

The feature DL interference mitigation enables the UE to receive an indication about a potential increase in the DL adjacent channel interference level (e.g. due to adjacent GSM carriers). The corresponding signalling indication is conveyed in broadcast messages SIB5, SIB5bis and SIB6. The UE may use this indication to mitigate the DL interference, e.g. by using optimized Rx filtering.
