Optimizing Resource Allocation in STAR-RIS-Aided Simultaneous Wireless Information and Power Transfer Systems with Rate Splitting Multiple Access

The core message of this paper is to propose a novel system that incorporates a simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) with simultaneous wireless information and power transfer (SWIPT) using rate splitting multiple access (RSMA) to optimize both the sum rate of information decoding receivers (IDRs) and the total harvested energy at energy harvesting receivers (EHRs).
