UL RSRP differences

Could someone explain the differences in these 3 itens?

  • UL DMRS RSRP = -98.94 dBm
  • Serve Cell UL SRS RSRP = -98.16 dBm
  • UL Demodulation RSRP = -100.71 dBm

First is DMRS for PUSCH.
Second is SRS RSRP (but that is measured in Uplink by gNodeB, not at UE side).
I don’t know what is the third one…
