TL;DR: Based on simulations of a typically formed Chinese intercity passenger train hauled respectively by major types of the locomotives on a certain railway line in China, the authors analyzes the changes of the tractionenergy cost intensity and passenger transport efficiency of the train with varying its passenger capacity utilization rate and target speed.

TL;DR: In this paper, a two-way relay non-orthogonal multiple access (TWR-NOMA) system is investigated, where two groups of NOMA users exchange messages with the aid of one half-duplex (HD) decode-and-forward (DF) relay.

TL;DR: In this article, the authors investigated the downlink coverage performance of RIS-aided multi-cell NOMA networks and derived closed-form coverage probability expressions for the paired users.

TL;DR: In this article, a cache-enabling UAV cellular network is investigated, where the massive access capability is enhanced by applying non-orthogonal multiple access (NOMA), and a mobile UAV base station which caches the popular contents to release the pressure on wireless backhaul links, is deployed to assist the delivery of large volume multimedia contents for ground users.

TL;DR: In this paper, the authors investigated the performance of RIS aided downlink NOMA multi-cell networks, where the energy of incident signals at RISs is split into two portions for transmitting and reflecting.
