In this paper, a novel intelligent transmission surface (ITS) assisted terahertz (THz) wideband massive multiple-input multiple-output (MIMO) non-terrestrial communication architecture is conceived, which is capable of reducing the hardware cost and power consumption remarkably compared to traditional architectures. To further address the beam squint impact in the THz wideband system, an angle-based hybrid beamformer is designed for the proposed architecture, which can effectively suppress the beam squint and maintain high spectral efficiency (SE) performance. Numerical results demonstrate that the proposed scheme is capable of approaching the optimal full-digital architecture in terms of the SE performance, and the proposed method can achieve significant energy efficiency performance gains over other existing architectures.
