As wireless communication demands continue to rise, Non-Orthogonal Multiple Access (NOMA) has emerged as a key technology for next-generation networks, including 5G and beyond. Unlike Orthogonal Multiple Access (OMA), NOMA enables multiple users to share the same resources by transmitting signals at different power levels, significantly improving spectral efficiency. This paper addresses the challenges of user pairing and dynamic NOMA/OMA switching in downlink NOMA systems, specifically within vehicular networks. We propose an optimization framework that jointly addresses Base Station- Vehicular User (BS-VU) association, channel assignment, and dynamic switching between OMA and NOMA to minimize power consumption. Simulation results demonstrate that our approach can effectively associate VUs to BS and dynamically switch between NOMA and OMA while meeting Quality of Service (QoS) requirements. These findings underline the viability of NOMA as a critical enabler of efficient and scalable communication in future networks.
