DOI: 10.1109/tvt.2022.3227590
Abstract: This paper considers an integrated multicast and unicast downlink communication system using the non-orthogonal multiple access (NOMA) scheme assisted by an intelligent reflecting surface (IRS). We aim to maximize the unicast data rate while keeping… read more here.

DOI: 10.1109/twc.2018.2858223
Abstract: The demand for providing multicast services in cellular networks is continuously and fastly increasing. In this paper, we propose a non-orthogonal transmission framework based on layered-division multiplexing (LDM) to support multicast and unicast services concurrently… read more here.
