RSRQ calculation

TRANSCRIPT

Power per RE (w)0 dB003 dB2500500Load %
McNally, Dave: Load (%)indicates serving cell load, does not include interference from adjacent cellsRSSI (w)
McNally, Dave: RSSIthe total measure over 12 sub-carriers including RS from the serving cell, traffic in the serving cell and adjacent cell interferenceRSRP (w)
McNally, Dave: RSRPThe average power present in only the RSRSRQ (dB)
McNally, Dave: RSRQ (dB)Resulting ratio of RSRP power and RSSIRSRQ = RSRP/RSSIPower (w)0.1RERS7500%0.170.083-3.0 dB10.20.0830.0831000 RSRP Boost
McNally, Dave: RSRP Power Boost (dB)the amount of additional power transmited in the RS, can improve RSRQ under cell loaded state or where external intererence is present0.30.0830 dB0.40.08333333330%0External Interference
McNally, Dave: External Loadthis is just a simple scaling factor that intoduces interference that may be present from adjacent cells0.530%00 0.660%00.780%0#RB#SCPower/Carrier (w)Power/SC (w)Power/RS (w)0.8100%02530010.00330.00330.90.08330.0 dBm5.2 dBm5.2 dBm

Pathloss (dB)
McNally, Dave: Pathlossenter some arbitary value of pathloss e.g.100dB130

RSSI (w)RSRP (w)10.0033

RSSI (dBm)RSRP (dBm)RSSI - RSRP Offset-100.0-124.8-24.8 dB

RSSI and RSRP Measured only in symbols containing RSRSRQ calculation is done for a single RB using the entered value for power, no pathloss is used since the values are relative to each other and PL (or TxPwr in fact) will not affect this simple calculator

this will be the power difference between RSSI and RSRP for a given channel BW (RB)
