•The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP/RSRQ
•In LTE, RSRP and RSRQ are based on Cell-specific Reference Signal (CRS).
However, in NR there is no CRS •RSRP / RSRQ definition in NR is based on other physical signals as shown in the following table.
Category | Physical signal for measurement |
RSRP | Synchronization Signal Reference signal received Power (SS-RSRP) |
RSRP | CSI reference signal received power (CSI-RSRP |
RSRP | SRS reference signal received power (SRS-RSRP) |
Category | Physical signal for measurement |
RSRQ | Synchronization signal Reference signal Received Quality (SS-RSRQ) |
RSRQ | CSI reference signal received quality (CSI-RSRQ) |
Category | Physical signal for measurement |
SINR | CSI signal-to-noise and interference ratio (CSI-SINR |
SINR | Synchronization Signal Signal-To-Noise and interference Ratio (SS-SINR) |
