TL;DR: In this paper, a novel non-orthogonal multiple access (NOMA) based cache-aided mobile edge computing (MEC) framework is proposed, where a long-term reward maximization problem is formulated that involves a joint optimization of the task offloading decisions, computation resource allocation, and caching decisions.

TL;DR: The diversity of both the near and far users is analyzed to demonstrate that the use of SWIPT will not jeopardize the diversity order compared to the conventional NOMA, and new analytical expressions for outage probability are derived.

TL;DR: This work investigates the physical layer security of the downlink in IRS-aided non-orthogonal multiple access networks in the presence of an eavesdropper, where an IRS is deployed for enhancing the quality by assisting the cell-edge user to communicate with the base station.

TL;DR: A dual-hop decode-to-forward cooperative system is considered where multiple relays are with finite energy storage and can harvest energy from the destination and the system performance is improved by enlarging the area of the circle and the density of the relays and the energy storage size has impacts on the performance of considered networks.

TL;DR: This paper advocates a pair of strategies in non-orthogonal multiple access (NOMA) in unmanned aerial vehicles (UAVs) communications, where multiple UAVs play as new aerial communications platforms for serving terrestrial NOMA users.
