Title:
BEAMFORMING METHOD AND EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2017/054201
Kind Code:
A1
Abstract:
The embodiments of the invention provide a beamforming method and equipment. The beamforming method comprises: performing, by wireless network equipment, first polarization on signals to be transmitted by two rows of first dual-polarized antennas, respectively, and performing, by the wireless network equipment, second polarization on signals to be transmitted by two rows of second dual-polarized antennas, respectively; performing an in-phase procedure on the signals to be correspondingly transmitted by the two rows of the first dual-polarized antennas, performing an out-of-phase procedure on the signals to be correspondingly transmitted by the two rows of the second dual-polarized antennas, and transmitting, by corresponding dual-polarized antennas, the signals to form a beam pattern. The embodiment implements four rows of the dual-polarized antennas to transmit signals of one beamforming output so as to form a beam pattern, and eight rows of the dual-polarized antennas to transmit signals of two beamforming outputs so as to form two beam patterns. The embodiment is not required to increase a beamforming port, and can prevent an increase in network resource expenditure resulting from an increase in beamforming ports. Further, the signals undergone the in-phase procedure and the out-of-phase procedure are orthogonal in polarization directions thereof, therefore, the beam pattern formed is a power combined beam pattern, and not an amplitude combined beam pattern.
