Title:
BEAM ALIGNMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/208742
Kind Code:
A1
Abstract:
The present application provides a beam alignment method and apparatus. The method comprises: a network device receives a first uplink signal from a terminal device; the network device calculates a conjugate phase corresponding to the first uplink signal, and determines, according to the conjugate phase, a narrow beam opposite to the direction of arrival of the first uplink signal as a target transmission beam that the network device and the terminal device are aligned with; and the network device communicates with the terminal device by means of the target transmission beam. Thus, the number of times of beam scanning and the time consumption of beam alignment can be reduced, the beamforming convergence speed is improved, and then the accuracy of beamforming is improved.
