Abstract

The embodiment of the invention provides a beam forming method, network equipment, a terminal and a storage medium. The beam forming method comprises the following steps: obtaining a first beam forming weight in a first polarized antenna direction according to direction of arrival information; obtaining a phase difference between two polarized antenna directions according to the precoding matrix indication information; obtaining a second beam forming weight in the second polarized antenna direction according to the first beam forming weight and the phase difference; and generating a shaped beam according to the first beam forming weight and the second beam forming weight. According to the embodiment of the invention, beam forming in the first polarization direction is carried out through the direction of arrival algorithm, so that the shaped beam of the network equipment is narrower, the energy concentration degree is higher, and the signal-to-noise ratio is effectively improved; the precoding matrix indication information is utilized to construct beam forming in the second polarization direction, so that one polarized antenna sends two layers of data, the antenna gain of each layer of data is increased, and the anti-interference capability and the transmission traffic of a transmission channel are effectively improved.

Description

technical field [0001] The present application relates to the technical field of wireless network communication, and in particular to a beamforming method, network equipment, terminal and 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 array element in the antenna array, so that significant array gain can be obtained. Therefore, beamforming technology has great advantages in expanding coverage, improving edge throughput, and interference suppression. [0003] In the related art, a direction of arrival (Direction of Arrival, DOA) algorithm is used for beamforming, and a DOA angle is used to calculate a beamforming weight, so that a narrower beam with more concentrated energy can be generated. However, the DOA algorithm can only carry one layer of services in one antenna polarization direction, the anti-interference ab...
