IRS Aided MEC Systems with Binary Offloading: A Unified Framework for Dynamic IRS Beamforming
Guangji Chen, Qingqing Wu
In this paper, we develop a unified dynamic intelligent reflecting surface (IRS) beamforming framework to boost the sum computation rate of an IRS-aided mobile edge computing (MEC)…
Active IRS Aided Multiple Access for Energy-Constrained IoT Systems
Guangji Chen, Qingqing Wu, Chong He +3
We investigate the fundamental multiple access (MA) scheme in an active intelligent reflecting surface (IRS) aided energy-constrained Internet-of-Things (IoT) system, where an acti…
IRS-aided Wireless Powered MEC Systems: TDMA or NOMA for Computation Offloading?
Guangji Chen, Qingqing Wu, Wen Chen +2
An intelligent reflecting surface (IRS)-aided wireless powered mobile edge computing (WP-MEC) system is conceived, where each device's computational task can be divided into two pa…
Throughput Analysis of UAV-assisted CellularNetworks by Matérn Hardcore Point Process
Mengbing Liu, Guangji Chen, Ling Qiu
Unmanned aerial vehicles (UAVs) are expected to coexist with conventional terrestrial cellular networks and become an important component to support high rate transmissions. This p…
Analysis and Optimization of Random Cache in Multi-Antenna HetNets with Interference Nulling
Kangda Zhi, Guangji Chen, Ling Qiu +2
From the perspective of statistical performance, this paper presents a framework for the per-user throughput analysis in random cache based multi-antenna heterogeneous networks (He…
