In this paper, we consider the user fairness in partial non-orthogonal multiple access (P-NOMA) system which was proposed in our previous work. In the P-NOMA system, the interference of NOMA can be managed by adjusting the overlap ratio between users. In our previous works, we considered the enhancement of sum of achievable rate. In this paper, we investigate the performance of P-NOMA in terms of user fairness. For reflecting user fairness on P-NOMA systems, we first define the metric to represent user fairness and then observe the target performance metric according to overlap ratio. In addition, we propose a feasible operating method to achieve the user fairness.
