Abstract

In this letter, we investigate the optimal EH-ratio and beamwidth selection in millimeter wave (mmWave) communications. Specifically, users in mmWave communications operate in slotted mode, where each frame consists of three continuous segments—energy harvesting, beam-searching, and data transmissions. In this sense, we propose a joint optimal EH-ratio and beamwidth selection scheme by maximizing the achievable throughput. Simulation results validate the performance superiority of the proposed scheme.
