Abstract

We study a wireless information and energy supply control system with frequency-division operation. In the considered system, a control station (CS) with a massive antenna array transmits energy and control information to multiple control terminals (CTs), and the CTs simultaneously transmit sensing information to the CS using harvested energy. The objective of this Letter is to minimize the maximum control cost among all the CTs through resource allocation while satisfying the transmission rate requirements of both the sensing and control information. The transmission rates are first derived, and then a relationship between control cost and power allocation is established. Finally, we prove that all the CTs should have the same control cost to meet the min-max criterion, based on which a resource allocation scheme is proposed for the min-max problem. Numerical results indicate that the proposed resource allocation scheme is able to significantly reduce the system control cost.
