Title:
METHOD FOR SENDING BEAMFORMING SIGNAL AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/001479
Kind Code:
A1
Abstract:
The present application provides a method for sending a beamforming signal and a base station device. The method is applied to a base station side, and comprises: determining position information of a user equipment (UE) in a cell, acquiring environmental information within the range of the cell, and determining surrounding object information of the UE according to the environmental information; determining, according to the position information and the surrounding object of the UE, a communication path used for communicating with the UE and a corresponding oriented beam direction; and performing beamforming on a downlink signal in the oriented beam direction, and sending the downlink signal to the UE. The method provided by embodiments of the present application does not require beam scanning; after environmental information within the range of a cell is acquired, a base station directly irradiates a beam to the position of a user according to a transmission path, and the user can also perform measurement using a receive beam spread at a smaller angle, thus implementing a fast transmission speed and high transmission precision.
