Hi Mr.Wang, Question1：At openair1/PHY/NR_UE_ESTIMATION/nr_ue_measurements.c line 104，why suntract 10log10(2012)?How to understand this. Question2:At openair1/PHY/NR_UE_ESTIMATION/nr_ue_measurements.c line 287,the log displays RRC Measurements,but the prefix express the work is PHY,PHY or RRC? Thank you!
