In LTE, these equate to reference signal received power (RSRP) and reference signal received quality (RSRQ), which are measures of the strength and quality of reference signals. So, RSRQ = RSRP / (2RSRPN/N) =1/2=0. Hello All, I am looking for following ideal values of SINR and . The signal levels both RSRP and SIR shows the planning of LTE-A network in. 5dB (bad) to -3dB (good). You can think of this as the one similar to CPICH RSCP in WCDMA.
