Abstract: This letter investigates a reconfigurable intelligent surface (RIS)-aided multiple-input-single-output (MISO) communication system which uses rate-splitting multiple access (RSMA) protocol. A multi-antenna base-station (BS) communicates with $K$ cell-edge users using RSMA protocol. Each user is assisted… read more here.

Abstract: In this paper, we study the performance improvement methods for a cell-edge user of two-user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end, we propose two cooperative relaying schemes, namely ON/OFF-full-duplex relaying… read more here.
