Abstract

The present invention provides a beamforming method, device, base station, and computer-readable storage medium. By acquiring the location information and CSI information of the terminal, the DOA angle of the antenna is determined according to the location information, and combined with the antenna information and the The first single-polarization DOA weight is obtained from the DOA angle, and the dual-polarization DOA weight of the antenna is obtained according to the CSI information and the first single-polarization DOA weight, and an endowment that includes polarization information and can support multiple streams is generated. Type weights can effectively solve the problem that DOA weights can only be used for a single stream, and can obtain better shaping effects under multiple antennas to improve user experience.

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, resulting in inaccurate calculation of weighting weights, BF (Beamforming, beamforming) 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 accor...
