WI Acronym:  FS_NR_RIM
Rapporteur:  Ms. Wu, DanChina Mobile Com. Corporation

The objective of this Study is to investigate possible mechanisms for mitigating the impact of remote base station interference in unpaired spectrum focusing on synchronized macro cells with semi-static DL/UL configuration in co-channel, including:
  • Study mechanisms for improving network robustness and addressing strong remote base station interference, including potential UE side's enhancement [RAN1]
  • Study mechanisms for identifying which gNB(s) generate strong remote interference, including the following aspects:
    • Potential Reference signal design for gNB to identify that it creates strong inter-gNB interference to some victim gNB [RAN1]
      • Existing reference signals are starting points of discussion.
    • Mechanism for gNB to start and terminate the transmission/detection of the reference signal(s) [RAN1, RAN3]
  • Study the potential additional coordination among gNBs for mitigating remote interference [RAN3]
