Recent Advances in Near-Field Beam Training and Channel Estimation for XL-MIMO Systems
Ming Zeng, Ji Wang, Wanming Hao +3
Extremely large-scale multiple-input multiple-output (XL-MIMO) is a key technology for next-generation wireless communication systems. By deploying significantly more antennas than…
Joint Power Allocation and Antenna Placement for Pinching-Antenna Systems under User Location Uncertainty
Hao Feng, Ming Zeng, Xingwang Li +3
Pinching antenna systems have attracted much attention recently owing to its capability to maintain reliable line-of-sight (LoS) communication in high-frequency bands. By guiding s…
Six-Dimensional Movable Antenna Enabled Wideband THz Communications
Wencai Yan, Wanming Hao, Yajun Fan +3
In this paper, we investigate a six-dimensional movable antenna (6DMA)-enabled wideband terahertz (THz) communication system with sub-connected hybrid beamforming architecture at t…
Sum Rate Maximization for NOMA-Assisted Uplink Pinching-Antenna Systems
Ming Zeng, Ji Wang, Xingwang Li +3
In this paper, we investigate an uplink communication scenario in which multiple users communicate with an access point (AP) employing non-orthogonal multiple access (NOMA). A pinc…
