Summary:In accordance with one embodiment of the present disclosure, a method of operating a wireless communication device for adaptive beamforming of a base station includes the following steps of: receiving a sounding packet from the base station through a plurality of subcarriers; generating first channel information corresponding to first subcarriers of the plurality of subcarriers by using the sounding packet; performing an interpolation operation using the first channel information to generate second channel information corresponding to second subcarriers of the plurality of subcarriers; generating first beamforming feedback including the first channel information and the second channel information; and transmitting the first beamforming feedback to the base station. Therefore, the present invention is capable of reducing the size of a chipset for wireless communication. 본 개시의 일 실시예에 따른 기지국의 적응적인 빔포밍을 위한 무선 통신 장치의 동작 방법에 있어서, 상기 기지국으로부터 복수의 부반송파들을 통해 사운딩 패킷을 수신하는 단계, 상기 사운딩 패킷을 이용하여 상기 복수의 부반송파들 중 제1 부반송파들에 대응하는 제1 채널 정보들을 생성하는 단계, 상기 복수의 부반송파들 중 제2 부반송파들에 대응하는 제2 채널 정보들을 생성하기 위해 상기 제1 채널 정보들을 이용한 보간 동작을 수행하는 단계, 상기 제1 채널 정보들 및 상기 제2 채널 정보들을 포함하는 제1 빔포밍 피드백을 생성하는 단계 및 상기 제1 빔포밍 피드백을 상기 기지국에 송신하는 단계를 포함한다.
