Movable Antenna-Enhanced Multiuser Communication: Optimal Discrete Antenna Positioning and Beamforming
Yifei Wu, Dongfang Xu, Derrick Wing Kwan Ng +2
Movable antennas (MAs) are a promising paradigm to enhance the spatial degrees of freedom of conventional multi-antenna systems by flexibly adapting the positions of the antenna el…
Integrated Sensing and Communication in Coordinated Cellular Networks
Dongfang Xu, Chang Liu, Shenghui Song +1
Integrated sensing and communication (ISAC) is a promising technique to provide sensing services in future wireless networks. Numerous existing works have adopted a monostatic rada…
Active IRS-Aided MIMO Systems: How Much Gain Can We Get?
Zeyan Zhuang, Xin Zhang, Dongfang Xu +1
Intelligent reflecting surfaces (IRSs) have emerged as a promising technology to improve the efficiency of wireless communication systems. However, passive IRSs suffer from the ``m…
Joint BS Selection, User Association, and Beamforming Design for Network Integrated Sensing and Communication
Yiming Xu, Dongfang Xu, Lei Xie +1
Different from conventional radar, the cellular network in the integrated sensing and communication (ISAC) system enables collaborative sensing by multiple sensing nodes, e.g., bas…
A Framework for Transmission Design for Active RIS-Aided Communication with Partial CSI
Gui Zhou, Cunhua Pan, Hong Ren +4
Active reconfigurable intelligent surfaces (RISs) have recently been proposed to compensate for the severe multiplicative fading effect of conventional passive RIS-aided systems. E…
Energy-Aware Resource Allocation and Trajectory Design for UAV-Enabled ISAC
Ata Khalili, Atefeh Rezaei, Dongfang Xu +1
In this paper, we investigate joint resource allocation and trajectory design for multi-user multi-target unmanned aerial vehicle (UAV)-enabled integrated sensing and communication…
