A Simple Method of Proportional Fairness-based Resource Allocation for Power-domain NOMA

Abstract

This paper proposes a simple method of proportional fairness-based user pairing and power allocation for power-domain NOMA. Compared with the conventional method, the proposed method simplifies the fairness calculation and comparison algorithm, by which the computational complexity reduces significantly. Using computer simulations, we show that its characteristics are identical to those of the conventional method.
