Observation 1: RLF report is used f

Observation 1: RLF report is used for both coverage optimization and mobility robustness optimization.In SA NR, the support of mobility is even more challengi吨， especially for HF due to the fast channel variation and vulnerability to the environment. The coverage optimization and mobility performance optimization are generalproblems, which exist in both HF and LF deployment and need to be addressed in NR. Considering the RLF report can provide benefit for the operator to optimize the network planning and configuration, RAN2 can consider to supportitfor SANRActually, RLF report has already supported in EN-DC, with the similar purpose to help MN to make proper configuration for SN due to UE mobility. So different SCG failure cases are supported. When SCG failure occurs, theUE needs to report the SCGFailurelnforma!ion to the MeNB instead of triggering the re-establishment upon SgNB failure. Furthermore, UE includes two measurement results i.e. measurement results according to the MN configuration and measurement results according to the SN configuration in the SCGFailurelnformation message. For RLF report in SA NR,only the measurement configuration of MN needs to be reported,which is much simpler than SCG failure report. So we don`t see the obstacles to support RLF report for SA NR.
