Low-Complexity Optimization for Near-Field STAR-RIS Uplink NOMA
We address an extremely large (XL) simultaneously transmitting and reflecting intelligent reconfigurable surface (STAR-RIS) to the uplink non-orthogonal multiple access (NOMA) to improve the sum rate. We reformulate the sum rate maximization problem to be solvable with a low-complexity nonlinear optimization algorithm and investigate the near-field effect of the STAR-RIS on the uplink NOMA according to the STAR-RIS array configurations.
