Energy-Efficient Wireless Communications With Distributed Reconfigurable Intelligent Surfaces

Zhaohui Yang et al.

Summary: This paper investigates the problem of resource allocation for a wireless communication network with distributed reconfigurable intelligent surfaces (RISs). The goal is to maximize the energy efficiency by dynamically controlling the on-off status of each RIS and optimizing the reflection coefficients matrix of the RISs. Two iterative algorithms are proposed for the single-user case and multi-user case to solve the joint optimization problem of transmit beamforming and RIS control.

Constrained Utility Maximization in Dual-Functional Radar-Communication Multi-UAV Networks

Xinyi Wang et al.

Summary: This paper investigates the network utility maximization problem in a dual-functional radar-communication multi-UAV network, proposing a computationally practical method to solve this NP-hard problem by decomposing it into three sub-problems and introducing three mechanisms based on spectral clustering, coalition game, and successive convex approximation. The proposed algorithm significantly improves the minimum user data rate and fairness of the network while increasing network utility with lower power consumption and similar localization accuracy compared to conventional techniques.

Joint Waveform Design and Passive Beamforming for RIS-Assisted Dual-Functional Radar-Communication System

Xinyi Wang et al.

Summary: The dual-functional radar-communication (DFRC) technique is considered a promising component in emerging platforms, but waveform design limitations can lead to high multi-user interference (MUI) and degraded communication performance. Inspired by Reconfigurable Intelligent Surface (RIS) applications in mitigating MUI, this paper investigates joint waveform design and passive beamforming in RIS-assisted DFRC systems. Simulation results show that with RIS assistance, system throughput can be significantly improved and the obtained beampattern matches the target transmit beampattern better than scenarios without RIS.
