Partitioning a transmit array into sub-arrays generating multiple coordinated Airy beams reduces sensitivity to obstacle-geometry estimation errors compared to single-Airy beamforming.
The work introduces a two-stage non-uniform polar codebook and a fast-scanning 1D codebook for Airy beam training that cut overhead by 54% and 93% respectively versus prior hierarchical methods while preserving spectral efficiency.
An analytical framework characterizes Airy beam propagation in near-field XL-MIMO, derives aperture and spacing constraints for distortion-free trajectories, and quantifies trade-offs versus Gaussian beams.
A review of bending beam fundamentals, applications, and challenges for THz wireless communications, with a 140 GHz metasurface prototype demonstrating 1.6 Gbps through a blocked link.
A tutorial on HISAC showing how reconfigurable holographic surfaces enable cost-efficient ultra-massive MIMO for joint communication and sensing in 6G under hardware constraints.
