Poster: α Fair Resource Allocation for RIS-Assisted NOMA V2X Systems with Imperfect Phase Compensation

Reconfigurable intelligent surface (RIS)-assisted non-orthogonal multiple access (NOMA) system is a key tech-nology for next-generation wireless communication systems to enhance coverage, optimize spectrum utilization, and increase throughput. In this poster, we examine Infrastructure-to- Vehicle (I2V) communication through RIS, employing a hybrid orthogo-nal multiple access (OMA)-NOMA system with imperfect phase compensation. We consider lower and upper bounds on the power allocation factor and formulate an optimization problem to achieve a-fairness among the vehicles. Additionally, we propose a vehicle pairing and power allocation strategy that ensures the achievable data rate is greater than its OMA rate. Through extensive simulations, we compare and show that the proposed algorithm outperforms state-of-the-art algorithms.
