Abstract

Embodiments of the present disclosure provide a method and apparatus for hybrid beamforming in a base station as well as a method and apparatus for hybrid beamforming in a mobile terminal. The method for hybrid beamforming in a base station comprising: calculating a wideband analog beamforming matrix based on long-term-level estimation of a physical channel; quantizing the wideband analog beamforming matrix to obtain a quantized wideband analog beamforming matrix; applying the quantized wideband analog beamforming matrix to the physical channel to obtain an effective channel of the physical channel; calculating a sub-band digital beamforming matrix based on short-term-level estimation of the effective channel; and performing hybrid beamforming on downlink signals with the sub-band digital beamforming matrix and the quantized wideband analog beamforming matrix. The hybrid beamforming solution according to the embodiments of the present disclosure makes massive MIMO systems more practical and cost-effective to deploy.
