Specify the CSI feedback mode as one of 'RI-PMI-CQI', 'AI CSI compression', or 'Perfect CSI'. In all modes, the UE can perform perfect or practical channel estimation using CSI-RS. RI-PMI-CQI: The UE selects and reports the appropriate RI, PMI, and CQI periodically. The gNodeB ...
While performingSS-RSRPmeasurements for L1, UE can be configured to measureCSI-RSas well.CSI-RSmay be transmitted with different transmit power compared toSync Signals(SS) andPBCH-DMRS. In this casegNBshall provide offset information to UEs so that it can be taken into account during the meas...

This includes all physical signals, DRMS, channel state information reference signals or CSI-RS, and phase tracking reference signals or PTRS, this also includes any resource block that is fully or even partially used by synchronization signal blocks or SSB, SSB are explained in detail in another...
In short, the role of SRS is similar to CSI RS. CSI-RS is a reference signal for downlink channel quality estimation independent of PDSCH DMRS and SRS is a reference signal for uplink channel quality estimation independent of PUSCH DMRS...

The RSRPB measurements are defined using SSS (SS-RSRPB). To simplify UE implementation (e.g. enable parallel RSRPB and RSARP calculation) SSS resources are recommended to be used similar to the SS-RSRPB measurements. In addition the PBCH DMRS and CSI-RS can be used to improve the accur...
