ABSTRACT
The paper characterizes the class of all concave resource allocation
problems in interference coupled wireless systems. An axiomatic
framework for interference functions proposed by Yates in 1995 is
used to model interference coupling in our paper. The paper shows
that there exists no transformation, which ensures concavity for all
