Abstract
A dynamic signal transmission structure based on a hybrid beamforming technology includes a radio-frequency module and an antenna array connected therewith. The radio-frequency module includes one or more radio-frequency link units connected in parallel, the antenna array includes one or more antenna sub-arrays, and each antenna sub-array is connected with one of the radio-frequency modules. The hybrid beamforming technology includes analog and digital beamforming. In this structure, the analog beamforming parameters and the digital beamforming parameters are constant, and the number of radio-frequency link units in the radio-frequency module, the number of antenna sub-arrays in the antenna array, the analog beamforming parameters, and the digital beamforming parameters are in a quantitative relation. The structure of the antenna array and the number of radio-frequency link units in each radio-frequency module can be adjusted dynamically under the condition where the performance is guaranteed, and accordingly, the hardware complexity is reduced.
