Hybrid Beamforming for Subarray-Level Movable Antenna Enhanced MU-MIMO Communications
Shanshan Zhang, Songjie Yang, Wenxuan Zhang +2
This study investigates subarray-level movable antenna (MA) architecture for multi-user MIMO (MU-MIMO) systems. Unlike conventional systems with fixed-position antennas (FPAs), the…
Flexible Cylindrical Array-Aided Secure Wireless Communications
Xiangyu Dong, Ran Yang, Songjie Yang +4
Flexible-geometry arrays based on movable antennas have shown considerable potential for improving wireless communication performance. In this letter, we investigate a multiuser mu…
Near-Field Multiuser Beam Training for XL-MIMO: An End-to-End Interference-Aware Approach with Pilot Limitations
Xinyang Li, Songjie Yang, Xiang Ling +3
Near-field propagation in extremely large-scale MIMO (XL-MIMO) enlarges the beam training (BT) search space by introducing an additional range dimension, which makes conventional c…
Indirect and Direct Multiuser Hybrid Beamforming for Far-Field and Near-Field Communications: A Deep Learning Approach
Xinyang Li, Songjie Yang, Boyu Ning +3
Hybrid beamforming for extremely large-scale multiple-input multiple-output (XL-MIMO) systems is challenging in the near field because the channel depends jointly on angle and dist…
Precoding Matrix Indicator in the 5G NR Protocol: A Tutorial on 3GPP Beamforming Codebooks
Boyu Ning, Haifan Yin, Sixu Liu +8
This paper bridges this critical gap by providing a systematic examination of the beamforming codebook technology, i.e., precoding matrix indicator (PMI), in the 5G NR from theoret…
Cross-field SNR Analysis and Tensor Channel Estimation for Multi-UAV Near-field Communications
Tianyu Huo, Jian Xiong, Yiyan Wu +3
Extremely large antenna array (ELAA) is key to enhancing spectral efficiency in 6G networks. Leveraging the distributed nature of multi-unmanned aerial vehicle (UAV) systems enable…
