CSI-RSRP versus SS-RSRP in RRC States

5G NR

Hi Experts,
CSI-RSRP is used only to RRC_Connected and SS-RSRP is used to RRC_Connected or RRC_Idle.
Am I correct?

There is no RRC Idle for 5G in NSA.
Only connected mode in 5G.
In NSA i.e. EN-DC.
SSB-RSRP is used for B1 measurements to trigger SCG addition.

Yes for SA.
For NSA, SS is used before SCG addirion, while both SS and CSI-RS could be used after SCG addition

Yes its correct

SS-RSRP is used for following.
If SS-RSRP is used for L1-RSRP,
RRC_CONNECTED intra-frequency.
Otherwise,
RRC_IDLE intra-frequency,
RRC_IDLE inter-frequency,
RRC_INACTIVE intra-frequency,
RRC_INACTIVE inter-frequency,
RRC_CONNECTED intra-frequency,
RRC_CONNECTED inter-frequency

CSI-RSRP is used for following.
If CSI-RSRP is used for L1-RSRP,
RRC_CONNECTED intra-frequency.
Otherwise,
RRC_CONNECTED intra-frequency,
RRC_CONNECTED inter-frequency
