Abstract--We study the selection of the rate allocation in mul-
tiple access channels (MAC). We consider MACs with different
rate regions. Namely, we investigate the polytope rate regions,
convex non-polytope rate regions, and non-convex rate regions.
Different operating points of the rate region possess different
properties in terms of efficiency, fairness, stability, etc. Our goal
is to provide guidelines for the choice of an operating point
using the above-mentioned criteria. We use two methodological
approaches: fairness function approach leading to an optimal
system operation point and game theoretic approach leading
to an equilibrium point. In particular, we use games with
correlated constraints. All fairness concepts and normalized Nash
