Maximum Average Uplink SINR

This results from uplink power control. For calibration alpha is set to 1.0 and P_0 is -106 dBm. Without interference the SINR would be exactly 10.4 dB, since the thermal noise power is -116.4 dBm. The received interference power from most nodes is far below -116.4 dBm and remains insignificant in the I + N sum. There are still some close by interferers where the received interference power is around or above the thermal noise power. Have a look at Figure 3 here:

This is with alpha = 0.6. With alpha = 1.0 N + I is almost a straight line at -116.4 dBm.

Thanks Maciej! So in in the uplink transmit power control calculation in your simulations, the delta_MCS value is not included by default?

Cheers,
Rex.

The parameter "Ks" is used for that. The code can be found in ......./scheduler/uplink/eNB/SchedulerBase.cpp in "doLinkAdaptationAndPowerControlAndInformUEs(). The value of Ks (default = 0) can be set in line 416 of the example config.py file.

Thanks for the pointer Maciej. Just to doublecheck, Ks is set to 0 for generating the 3GPP calibration curves?
Rex.

Thanks! Appreciate the speedy response.

Thanks Maciej Muehleisen, that solved my question.
