Efficiency Maximization for UAV-Enabled Mobile Relaying Systems with Laser Charging
Ming-Min Zhao, Qingjiang Shi, Min-Jian Zhao
This work studies the joint problem of power and trajectory optimization in an unmanned aerial vehicle (UAV)-enabled mobile relaying system. In the considered system, in order to p…
Intelligent Reflecting Surface Enhanced Wireless Network: Two-timescale Beamforming Optimization
Ming-Min Zhao, Qingqing Wu, Min-Jian Zhao +1
Intelligent reflecting surface (IRS) has drawn a lot of attention recently as a promising new solution to achieve high spectral and energy efficiency for future wireless networks.…
Angular-Domain Selective Channel Tracking and Doppler Compensation for High-Mobility mmWave Massive MIMO
Guanying Liu, An Liu, Rui Zhang +1
In this paper, we consider a mmWave massive multiple-input multiple-output (MIMO) communication system with one static base station (BS) serving a fast-moving user, both equipped w…
Efficient Resource Allocation for Relay-Assisted Computation Offloading in Mobile Edge Computing
Xihan Chen, Yunlong Cai, Qingjiang Shi +3
In this article, we consider the problem of relay assisted computation offloading (RACO), in which user A aims to share the results of computational tasks with another user B throu…
Randomized Channel Sparsifying Hybrid Precoding for FDD Massive MIMO Systems
Chang Tian, An Liu, Mahdi Barzegar Khalilsarai +3
We propose a novel randomized channel sparsifying hybrid precoding (RCSHP) design to reduce the signaling overhead of channel estimation and the hardware cost and power consumption…
