Power Control by GDoF Duality of Treating Interference as Noise.

In this letter, we revisit the duality of treating interference as noise from the generalized degrees-of-freedom (GDoF) perspective. Specifically, in a general K -user interference channel, where interference is treated as Gaussian noise, we demonstrate, for any given GDoF tuple and its power allocation, how to derive a power allocation that yields a dominant GDoF tuple in its reciprocal channel. ...
