BEAMFORMING METHOD AND DEVICE IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2022/010012

A1

According to an embodiment of the present specification, a beamforming method performed by a wireless device having an array antenna in a wireless communication system comprises the steps of: calculating a phase related to a target beamforming direction; determining antenna patterns related to the target beamforming direction from among antenna patterns preconfigured in relation to beamforming; and applying, to the array antenna, an antenna pattern based on the phase from among the antenna patterns related to the target beamforming direction. Each antenna included in the array antenna includes multiple feeding points and a variable reactance element connected to at least one feeding point among the multiple feeding points. The antenna pattern is related to at least one of i) a selection of at least one feeding point among the multiple feeding points and ii) a reactance value of the variable reactance element.
