An Efficient Benders Decomposition Approach for Optimal Large-Scale Network Slicing
Wei-Kun Chen, Zheyu Wu, Rui-Jin Zhang +3
This paper considers the network slicing (NS) problem which attempts to map multiple customized virtual network requests to a common shared network infrastructure and allocate netw…
An Efficient Convex-Hull Relaxation Based Algorithm for Multi-User Discrete Passive Beamforming
Wenhai Lai, Zheyu Wu, Yi Feng +2
Intelligent reflecting surface (IRS) is an emerging technology to enhance spatial multiplexing in wireless networks. This letter considers the discrete passive beamforming design f…
Random ISAC Signals Deserve Dedicated Precoding
Shihang Lu, Fan Liu, Fuwang Dong +4
Radar systems typically employ well-designed deterministic signals for target sensing, while integrated sensing and communications (ISAC) systems have to adopt random signals to co…
Quantized Constant-Envelope Waveform Design for Massive MIMO DFRC Systems
Zheyu Wu, Ya-Feng Liu, Wei-Kun Chen +1
Both dual-functional radar-communication (DFRC) and massive multiple-input multiple-output (MIMO) have been recognized as enabling technologies for 6G wireless networks. This paper…
HPE Transformer: Learning to Optimize Multi-Group Multicast Beamforming Under Nonconvex QoS Constraints
Yang Li, Ya-Feng Liu
This paper studies the quality-of-service (QoS) constrained multi-group multicast beamforming design problem, where each multicast group is composed of a number of users requiring…
