Abstract

Embodiments of the present application provide a beamforming method, a network device, a terminal, and a storage medium. The beamforming method includes: obtaining the first beamforming weight in the direction of the first polarized antenna according to the direction of arrival information; obtaining the phase difference in the direction of the two polarized antennas according to the precoding matrix indication information; The shape weight and the phase difference are used to obtain a second beamforming weight in the direction of the second polarized antenna; and a shaped beam is generated according to the first beamforming weight and the second beamforming weight. In the embodiment of the present application, the beamforming of the first polarization direction is carried out through the direction of arrival algorithm, so that the formed beam of the network equipment is narrower, the energy concentration is higher, and the signal-to-noise ratio is effectively improved; the precoding matrix is ​​used to indicate the information structure Beamforming in the second polarization direction enables one polarized antenna to transmit two layers of data, and the antenna gain of each layer of data increases, thereby effectively improving the anti-interference ability and transmission traffic of the transmission channel.

Description

technical field

[0001] The present application relates to the technical field of wireless network communication, and in particular, to a beamforming method, a network device, a terminal, and a storage medium. Background technique

[0002] Beamforming is a signal preprocessing technology based on antenna arrays. Beamforming generates directional beams by adjusting the weighting coefficients of each element in the antenna array, so that significant array gain can be obtained. Therefore, beamforming technology has great advantages in extending coverage, improving edge throughput, and interference suppression.

[0003] In the related art, a Direction of Arrival (DOA) algorithm is used for beamforming, and the DOA angle is used to calculate the beamforming weight, which can generate a narrower beam with more concentrated energy. However, the DOA algorithm can only carry one layer of services in one antenna polarization direction, and the anti-interference ability of the transmis...
