MIMO Assisted Networks Relying on Intelligent Reflective Surfaces
Tianwei Hou, Yuanwei Liu, Zhengyu Song +3
Intelligent reflective surfaces (IRSs) are invoked for improving both spectral efficiency (SE) and energy efficiency (EE). Specifically, an IRS-aided multiple-input multiple-output…
Non-Orthogonal Multiple Access in UAV-to-Everything (U2X) Networks
Tianwei Hou, Yuanwei Liu, Zhengyu Song +2
This article investigates the non-orthogonal multiple access (NOMA) enhanced unmanned aerial vehicle (UAV)-to-Everything (U2X) frameworks. A novel 3-Dimension framework for providi…
Cache-Aided NOMA Mobile Edge Computing: A Reinforcement Learning Approach
Zhong Yang, Yuanwei Liu, Yue Chen +1
A novel non-orthogonal multiple access (NOMA) based cache-aided mobile edge computing (MEC) framework is proposed. For the purpose of efficiently allocating communication and compu…
Reinforcement Learning in Multiple-UAV Networks: Deployment and Movement Design
Xiao Liu, Yuanwei Liu, Yue Chen
A novel framework is proposed for quality of experience (QoE)-driven deployment and dynamic movement of multiple unmanned aerial vehicles (UAVs). The problem of joint non-convex th…
Learning Automata Based Q-learning for Content Placement in Cooperative Caching
Zhong Yang, Yuanwei Liu, Yue Chen +1
An optimization problem of content placement in cooperative caching is formulated, with the aim of maximizing sum mean opinion score (MOS) of mobile users. Firstly, a supervised fe…
Exploiting NOMA for UAV Communications in Large-Scale Cellular Networks
Tianwei Hou, Yuanwei Liu, Zhengyu Song +2
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 communi…
