  1. 1. RSRP、RSRQ、SINR Reporter: Richard.Su
  2. 2. RSRQ = RSRP/(RSSI/N) = RSRP*N/(IN_n + ρ*12*N*Psc) SINR=S/(IN_m) Where N is # of PRBs(per cell resource blocks) for RSRQ M is # of PRBs allocated to UE based on which SINR is measured Psc is average Rx power per subcarrier. In case of no power boost for RS, Psc=RSRP. IN_n is Interference plus noise over N PRBs used for RSRQ measurement IN_m is Interference plus noise measured over M PRBs allocated to UE (for SINR). In case that I+N is evenly distributed in all PRBs, then IN_n/N = IN_m/M. ρ: loading (% of subcarriers transmitted) over N PRBs for RSRQ S=Psc*M*12 is signal power. Without RS power boost and with evenly distributed interference over all PRBs, we have RSRQ = 1/[(1/SINR+ ρ)*12]
