Abstract

This paper investigates the power control problem for the uplink of a non-orthogonal multiple access (NOMA) system with two cells. The game-theoretic approach is used to study the stability of distributed power control algorithms. It is shown that a unique Nash equilibrium exists if the Perron- Frobenius eigenvalue of a certain link gain matrix is less than one. A distributed power control algorithm is constructed, which is guaranteed to converge to the Nash equilibrium. Furthermore, the optimality property of the Nash equilibrium is studied. It is shown that the equilibrium is globally optimal in minimizing total power consumption, provided that some technical conditions are satisfied. Numerical results show that the power-controlled NOMA system outperforms its orthogonal counterparts.
