5G - RSRP  

 

 

 

NR-RSRP

RSRP stands for Reference Signal Recieved Power. The basic definiton of NR RSRP is same as LTE RSRP. The major difference from LTE RSRP is that NR RSRP is measured from the reference signal in SSB whereas LTE RSRP is measured from CRS(Cell Reference Signal).

When you get the RSRP value from measurement report (e.g, Measurement Report RRC message), it gives a positive integer value, not the dBm value. The mapping between the reported value and real power (measured quantity value) is defined in 3GPP as follows.

NOTE : You may do quick convert from Reported Value to Measured value by taking (Reported Value - 157)
