Abstract
In the development of 6G communication,achieving efficient signal transmission in the face of complex propagation en-vironments and obstacle blockage has become a key challenge.This paper systematically studies the non-stationary channel characteris-tics of large-scale antenna array systems and their impact on beam propagation,while proposing a series of new beam design schemes,including Bessel beams,Airy beams,and novel generalized beams,to address the issue of obstacle diffraction in high-frequency com-munication.Firstly,the paper conducts an in-depth analysis of non-stationary phenomena in Extremely Large-scale Multiple-Input Mul-tiple-Output(XL-MIMO)and Reconfigurable Intelligent Surface(RIS)with a focus on the path differences perceived by different an-tenna elements in complex propagation environments and their impact on channel modeling and beamforming.Secondly,novel beam de-signs are proposed for future wireless communication,featuring flexible trajectory control through Bessel beams,Airy beams,and novel generalized beams,to enable precise transmission that bypasses obstacles,significantly enhancing signal robustness and system spectral efficiency.Simulation results show that the performance of these new beams surpasses traditional beam designs in complex environ-ments,especially in scenarios involving obstacle blockage.关键词
