Abstract

Current research on Rate-Splitting Multiple Access (RSMA) focuses mostly on the case where the base station is fixed, and the use of UAVs as base stations for wireless communication is growing. The article introduces RSMA, a new type of non-orthogonal multiple access technique, to study the uplink transmission optimization problem of UAVs as base stations, and designs an algorithm based on the Augmented Lagrangian Method (ALM) and the Artificial Fish Swarm Algorithm (AFSA), which adds to the dynamic step size and field of view strategy, as well as the memory behavior of artificial fish. To solve the optimization problem further under the constraints of linear equations, a correction factor is introduced to the algorithm to constrain the behavior of the artificial fish. Finally, we simulate UAV-assisted uplink communication using RSMA, and the results demonstrate that this scheme has higher throughput than Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA), which is 11.60% higher than NOMA.
