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

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

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

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)
