pe II CSI targets MU-MIMO scenarios, transmission is limited to a maximum of two layers per device [14]. In order to reduce the overhead due to transmission of reference signals, 3GPP NR has moved away from the notion of continuously transmitted wideband cell-specific reference signals and instead has defined more flexible and configurable UE-specific reference signals transmitted on-demand. This transition has resulted in the definition of new UE measure- ment procedures based on the CSI-RSs. For this purpose, new metrics have been defined that will be explained in detail in the following: Synchronization Signal-Reference Signal Received Power (SS-RSRP) is defined as the linear average over the power contributions [in (Watts)] of the resource elements that carry secondary synchronization signals. The measurement time resource(s) for SS- RSRP are confined within SS/PBCH block measurement time configuration (SMTC) window size. If SS-RSRP is used for L1-RSRP as configured by reporting configura- tions, the measurement time resource(s) restriction by SMTC window size is not appli- cable. For SS-RSRP calculation, DM-RSs for PBCH and, if indicated by higher layers, CSI-RSs in addition to the secondary synchronization signals may be used. The SS- RSRP using DM-RS for PBCH or CSI-RS are measured by linear averaging over the power contributions of the resource elements that carry corresponding reference signals by considering the power scaling for the reference signals. If SS-RSRP is not used for L1-RSRP, the additional use of CSI-RSs for SS-RSRP determination is not applicable. The SS-RSRP is measured only over the reference signals corresponding to SS/PBCH blocks with the same SS/PBCH block index and the same physical-layer cell identity. If SS-RSRP is not used for L1-RSRP and higher layers indicate certain SS/PBCH blocks for performing SS-RSRP measurements, then SS-RSRP is measured only from the indi- cated set of SS/PBCH block(s). For frequency range 1, the reference point for the SS- RSRP is the antenna connector of
