Reconfigurable Codebook-Based Beamforming for RDARS-Aided mmWave MU-MIMO Systems
Chengwang Ji, Qing Xue, Haiquan Lu +4
Reconfigurable distributed antenna and reflecting surface (RDARS) is a new architecture for the sixth-generation (6G) millimeter wave (mmWave) communications. In RDARS-aided mmWave…
RDARS Empowered Massive MIMO System: Two-Timescale Transceiver Design with Imperfect CSI
Chengzhi Ma, Jintao Wang, Xi Yang +3
In this paper, we investigate a novel reconfigurable distributed antennas and reflecting surface (RDARS) aided multi-user massive MIMO system with imperfect CSI and propose a pract…
A Survey of Beam Management for mmWave and THz Communications Towards 6G
Qing Xue, Chengwang Ji, Shaodan Ma +4
Communication in millimeter wave (mmWave) and even terahertz (THz) frequency bands is ushering in a new era of wireless communications. Beam management, namely initial access and b…
On the Capacity Region of Reconfigurable Intelligent Surface Assisted Symbiotic Radios
Qianqian Zhang, Hu Zhou, Ying-Chang Liang +3
In this paper, we are interested in a reconfigurable intelligent surface (RIS)-assisted symbiotic radio (SR) system, where an RIS assists a primary transmission by passive beamform…
Reconfigurable Distributed Antennas and Reflecting Surface: A New Architecture for Wireless Communications
Chengzhi Ma, Xi Yang, Jintao Wang +3
Distributed Antenna Systems (DASs) employ multiple antenna arrays in remote radio units to achieve highly directional transmission and provide great coverage performance for future…
