Abstract:
The large-scale Internet of Things (IoTs) of B5G networks must face the arduous challenge of bandwidth limitations. Although millimeter wave (mmWave) technology can provide greater bandwidth at the cost of complex processors in harsh environments, it can be a possible solution for building large-scale IoTs, but its cost and power requirements become obstacles to widespread adoption. In this context, Re-configurable Intelligent Surfaces (RISs) can be a key technology to meet this challenge. In this paper, we study the B5G RIS-assisted MIMO simultaneous wireless-information and power-transfer (SWIPT) mmWave large-scale IoTs, where active BS transmitted beamformer and passive RIS reflection vector are jointly optimized to maximize the minimum signal-to-interference-plus-noise-ratio (SINR) of all the information decoders (ID) and at the same time, the minimum harvested power of all the energy receivers (ER) is maintained. Some simulation examples are given to demonstrate the effectiveness of the proposed system.
