Abstract
Hybrid beamforming technology is attractive for Terahertz (THz) communications to compensate the huge path loss, owing to the benefits of low hardware complexity and acceptable power consumption. Multiple hybrid beamforming architectures in the THz band, including the fully-connected (FC), array-of-subarray (AoSA) and dynamic array-of-subarray (DAoSA) architectures are investigated in this paper. Furthermore, the analysis and comparisons of the metrics of interest on spectral efficiency and power consumption of these three architectures are elaborated. Furthermore, multiple key open problems associated with the hybrid beamforming technology in the THz band are elaborated.
