  • 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!

  • HI, How to understand openair1/PHY/NR_UE_ESTIMATION/nr_ue_measurements.c from line 101 to 105: if (ue) return (10log10(ue->measurements.rsrp[gNB_index])- get_nr_rx_total_gain_dB(Mod_id,0) - 10log10(20*12)); return -140.0; Can you explain the three parameters about this code? Thank you!
