Energy-Efficient Resource Allocation in IRS-Assisted NOMA Networks: A Hierarchical Federated Learning Approach
To tackle signal blockage and energy constraints in next-generation networks, this letter proposes a mobile intelligent reflecting surface (IRS)-assisted multi-cell non-orthogonal multiple access (NOMA) network. An optimization problem is formulated to maximize system energy efficiency by jointly optimizing the IRS tra...
