“…The authors have discovered that the Pareto boundary of the secrecy rate region be achieved via the reasonable adjustment of transmit power and PS coefficients. An optimization procedure on maximizing the minimum downlink secrecy throughput of the multiuser OFDMA network with SWIPT that is composed of a BS and several receiver users has been carried out in [189] by considering the subcarrier allocation and PS ratio as inputs of the objective function. The secrecy rate of the weakest user has been aimed to be maximized in case that every user could wiretap all other users' subcarriers.…”

Increasing number of devices connected to the networks, applications and demands of new generation wireless communications cause very high energy consumption resulting in large amount of carbon emission. Thus, energy harvesting solutions together with accomplishing information transmission are required for energy efficient communications of new wireless communications generations such as 5G and 6G (i.e., 5G+). As such, due to the promise of energy efficient green communications, simultaneous wireless information and power transfer (SWIPT) techniques are expected to be indispensable component of 5G+. In this survey, the literature of multiuser SWIPT communications is reviewed for 5G+. Different multiuser SWIPT scenarios including multi-antenna communications, cooperative communications, network coding, communications security, and unmanned aerial vehicle (UAV)-enabled communication systems based on multiuser diversity and multiple access methods are thoroughly reviewed. The experimental studies are also discussed.
