SS reference signal received quality (SS-RSRQ)ĬSI reference signal received quality (CSI-RSRQ) SRS reference signal received power (SRS-RSRP) SS reference signal received power (SS-RSRP)ĬSI reference signal received power (CSI-RSRP) So RSRP / RSRQ definition in NR is based on other physical signals as shown in the following table. In LTE, RSRP and RSRQ is based on Cell specific Reference Signal (CRS).However, in NR SINR has become a formal measurement parameter used in RRC message. It is measured in most of LTE chips and this is one of the parameters that I most frequently check when I am doing physical layer performance troubleshooting. Of course, SINR is not a new parameter in NR. In NR, SINR seems to be an important power criteria.However, there are some differences as well between LTE and NR in terms of power definition and measurement as below. The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP / RSRQ. As in LTE, the most important criteria on Power Measurement is around RSRP, RSRQ.
