Abstract: Embodiments of the present disclosure relate to a beamforming solution for MIMO communication. The method implemented at a first device comprises: obtaining: a signature vector corresponding to a beam which is in a first direction from the first device to a second device, and a first channel covariance matrix associated with a transmission from the first device to the second device. The method further comprises generating, based on the signature vector and the first channel covariance matrix, a beamforming matrix to be used for the transmission from the first device to the second device. In this way, the accuracy of the beamforming matrix is improved and the calculation amount for the beamforming matrix is reduced.
