This will be the thresholds table. The parameters of the table are:

Estimation Window Size (EWND)
Maximum Tolerable Loss Probability Threshold (MTL)
Opportunistic Rate Increase (and Power Decrease) Probability Threshold (ORI)

We also calculate the needed success and failures to generate a rate or power change: Rate Increase or Power Decrease limits (RI-PD) Rate Decrease or Power Increase limits (RD-PI) Power Decrease limits (PD)

Mode EWND MTL ORI RI-PD RD-PI PD succ fails succ fails OfdmRate6Mbps 8 1 0.19861 7 8 2 OfdmRate9Mbps 11 0.397219 0.14556 10 5 7 2 OfdmRate12Mbps 15 0.291121 0.189753 13 5 11 3 OfdmRate18Mbps 21 0.379507 0.13624 19 8 14 3 OfdmRate24Mbps 27 0.27248 0.174216 23 8 20 5 OfdmRate36Mbps 37 0.348432 0.120773 33 13 25 5 OfdmRate48Mbps 45 0.241546 0.0523952 43 11 35 3 OfdmRate54Mbps 50 0.10479 0 50 6 45 5

Test that 6 is not enough.

Test that 7 is enough.

Increase rate until maximal rate.

Now we need more successful transmissions to make power decrease. As we are at maximal rate, the power is decreased when it is sure that the failures will not generate a rate decrease.

As rate hasn't change the same amount of success are needed. After 16*45 successful transmissions power is decreased to zero.

After 6 failures the power should be increased.
