TL;DR: This article studies direct communications between user equipments in the LTE-advanced cellular networks to provide better user experience and make profit accordingly.

TL;DR: This work discusses in detail the main differences in scientific research for wireless communications between the HSR operation scenarios and the conventional public land mobile scenarios, and the latest research progress in wireless channel modeling in viaducts, cuttings, and tunnels scenarios.

TL;DR: To handle increasing traffic, ensure passenger safety, and provide real-time multimedia information, a new communication system for HSR is required to replace the current GSM-railway (GSM-R) technology with the next-generation railway-dedicated communication system providing improved capacity and capability.

TL;DR: This paper investigates the application of simultaneous wireless information and power transfer (SWIPT) to cooperative non-orthogonal multiple access (NOMA) and proposes an iterative algorithm based on successive convex approximation (SCA) for complexity reduction, which can at least attain its stationary point efficiently.

TL;DR: This tutorial will be especially useful for researchers who work on RT algorithms development and channel modeling to meet the evaluation requirements of 5G and beyond technologies.
