If the power control is not activated then the iRSSunwanted is (see Figure 135):
iRSSunwanted Mathinline body iRSSunwanted = 33 (dBm) + 11 + 9 - (32.5 + 10 log(1) + 20 log(1000)) = -39.5 dBm

The power received by the Interfering link receiver (dRSSInterfering link receiver) is then:dRSSInterfering

Note: You should not confuse the dRSSInterfering link receiver and the dRSSVictim link receiver. Figure 111 illustrates their differences.

Since, the power control feature is activated the gain of the power control is determined according to the guidance given in ANNEX 14: on page 344. Since the dRSSInterfering link receiver is –37.5 dBm and:
Mathinline body -50 dBm (PC threshold) + 2 * PC step (5 dB) < –37.5 dBm < -50 dBm (PC threshold) + 3 * PC step (5 dB)
The gain of the power control (git PC) is 10 dB (Case (i+1) in ANNEX 14:). This means that the iRSSunwanted will be decreased by 10 dB, i.e. :
...
Mathinline body iRSSunwanted = -39.5 dBm -

= -49.5 dBm
...
Finally, if the threshold is decreased from –50 dBm to –70 dBm, the power control feature is activated. Since the dRSSInterfering link receiver is –37.5 dBm, this results in:

The gain of the power control is 20 dB (Case (n_step + 2) in ANNEX 14:). This means that the iRSSunwanted will be decreased by 20 dB, i.e. :
