A dual-stream beamforming method and device, which are used for solving the problems of poor beam directivity and poor beamforming effect of the current beamforming method. The method comprises: receiving a sounding reference signal (SRS) sent by a terminal, wherein the broadband occupied by the SRS is divided into a plurality of sub-bands by the terminal when the signal is sent; determining, on the basis of the SRS, a broadband beamforming vector corresponding to the broadband and a sub-band beamforming vector corresponding to each sub-band respectively; determining, on the basis of the broadband beamforming vector corresponding to the broadband or the sub-band beamforming vector corresponding to each sub-band, beamforming vectors in two polarization directions corresponding to each sub-band respectively; and for each sub-band, conducting dual-stream beamforming using the beamforming vectors in two polarization directions corresponding to the sub-bands. The dual-stream beamforming method of the present application has strong beam directivity and good beamforming effect. |
