<p style="text-align: justify;">In this paper, we aim to enhance spectrum efficiency in infrastructure-based Non-Orthogonal Multiple Access (NOMA) networks over Rayleigh fading channels. To achieve this, we introduce a Simultaneous Wireless Information and Power Transfer (SWIPT)-enabled Two-Way Relay (TWR) system. We then derive closed-form expressions for the outage probability for both near and far users in three-time slots. We design an iterative algorithm to solve this optimization problem efficiently. Finally, through numerical simulations, we demonstrate that our proposed scheme outperforms baseline benchmarks, confirming the effectiveness of our approach.</p>
