Sorry, although this is an old threat, I have to disagree to this comment. It confused the hell out of me...
The correct statement would be:
"Let's assume that when Tx power is set to aut/full it is 20dB = 100mW, when you reduce it by -3dB then the power would be half'd which is 17dB = 50mW, so if you want 4dB then it is -16dB which reduces it to 4dB = 2.5mW."
In short: -3dB reduces the power (measured in W) by half.
This article helps, have a look at the table further down:
