Title:
BEAM FORMING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/174351
Kind Code:
A3
Abstract:
Disclosed are a beam forming method and device. The method comprises: a base station receiving an uplink feedback signal from a terminal, and recovering parameters of channels from of various transmitting antennas of the base station to the terminal according to the uplink feedback signal; and the base station adjusting a transmitting phase of a data signal to be transmitted according to the parameters of channels from of various transmitting antennas to the terminal, and forming a beam in a specific direction. Through the present invention, a base station accurately adjusts a transmitting phase of a data signal to be transmitted according to a channel parameter fed back by a terminal, thereby being able to achieve accurate beam forming and locating, and also being able to simplify and even omit the real-time phase calibration of the interior of a device and antenna feeder engineering, achieve higher beam forming gain for various antenna modes, and facilitate achieving a multilayer multi-user operating mode of an LTE.
