Abstract

This paper investigates the application of simultaneous wireless information and power transfer (SWIPT) to nonorthogonal multiple access (NOMA). A new cooperative multiple-input-single-output (MISO) SWIPT NOMA protocol is proposed, where user 2 who has a strong channel condition acts as an energy-harvesting relay to help user 1 who has a poor channel condition. Our objective is to maximize the data rate of user 2 while satisfying the QoS requirement of user 1. The formulated problem boils down to a complicated nonconvex problem. We first use the semidefinite relaxation (SDR) technique to relax the nonconvex problem. Then, an iterative algorithm with the successive convex approximation (SCA) method is proposed to solve the relaxed problem. As a result, a local optimal solution is obtained. Motivated by the practical applications, the cooperative SWIPT NOMA protocol design in SISO case is investigated and a semiclosed-form solution is derived, which can strictly guarantee the global optimality. It is worth pointing out that the SCA method also admits a global optimal solution in SISO case. Simulation results show that the SWIPT-aided NOMA protocol outperforms the existing transmission protocols.
