Abstract

The invention provides a beamforming method and device, a base station and a computer readable storage medium, and the method comprises the steps: obtaining the position information and CSI information of a terminal, determining the DOA angle of an antenna according to the position information, obtaining a first single-polarized DOA weight through combining the antenna information with the DOA angle, and according to the CSI information and the first single-polarization DOA weight, obtaining a dual-polarization DOA weight of the antenna, and generating a shaping weight which contains polarization information and can support multiple streams, so that the problem that the DOA weight can only be used as a single stream can be effectively solved, a better shaping effect can be obtained under multiple antennas, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a beamforming method, device, base station and computer-readable storage medium. Background technique [0002] In the mobile communication system, due to the long distance between ground and air, the large transmission attenuation, and the large error of SRS (Sounding reference symbol, sounding reference signal) channel estimation, the weight calculation is inaccurate. The model effect is not ideal, which ultimately affects the user experience. In the ground-air communication system, large-scale antennas are usually used on the base station side, and effective shaping methods can improve user experience. In the conventional beamforming method, the base station calculates the relative angle according to its own location information and the location information of the terminal, constructs a shaping weight according to the angle information and the base station...
