Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/248108
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data transmission method and device. The method comprises: receiving a detection signal by means of M receiving antennas, wherein the detection signal is sent by a sending end by means of N sending antennas, and M and N are both greater than or equal to 2; calculating a channel matrix according to the detection signal; performing singular value decomposite (SVD) on the channel matrix to obtain a first matrix, wherein the first matrix comprises: first Nss columns of a first unitary matrix, Nss being a smaller value of M and N, and the first unitary matrix being an N*N matrix obtained by performing SVD on the channel matrix; performing unitary transformation on the first matrix to obtain a second matrix, wherein the second matrix is used for performing weight assignment on the N sending antennas by means of the sending end; and sending the second matrix to the sending end, so that the sending end can perform assignment on multiple sending antennas by using the second matrix, so as to improve the quality of the receiving signal from a receiving end.
