whats the correct range for rsrp and rsrq
Value 1 reported by UE to base station when RSRQ measured between -19.5 to -19 (-19.5<=RSRQ<-19dB). Value 34 reported when RSRQ measured greater than equal to -3dB (RSRQ>=-3dB). Integer value of RSRP and RSRQ reported by UE is included in RRC message (measurement report of serving cell) shown below:
RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site to -120 dBm at the edge of LTE coverage.
