title = "Transmit Power Minimization for IRS-Assisted Cooperative NOMA Networks with SWIPT",
abstract = "This paper considers an intelligent reflecting surface (IRS)-assisted downlink cooperative multiple-input single-output non-orthogonal multiple access (MISO-NOMA) networks with simultaneous wireless information and power transfer (SWIPT). The purpose of this paper is to minimize the transmit power of the base station subject to the successive interference cancellation and the users' requirements. The optimization problem formulated incorporates the transmission precoding vectors design, IRS beamforming design and power splitting ratio control, which is nonconvex. For solving this challenging problem, we propose a successive convex approximation based iterative algorithm by decomposing the problem formulated into two sub-problems. Our simulation results illustrate that the proposed IRS-assisted cooperative NOMA scheme with SWIPT has lower transmit power than that based on IRS-NOMA without SWIPT and on IRS-OMA with dynamic time allocation.",
