Abstract

본 발명에서는 무선 통신 시스템에서 물리 프로토콜 데이터 유닛(PPDU: Physical Protocol Data Unit) 송수신을 위한 방법 및 이를 위한 장치가 개시된다. 구체적으로, 무선 통신 시스템에서 무선 통신 장치가 물리 프로토콜 데이터 유닛(PPDU)을 전송하는 방법에 있어서, 레가시 프리앰블(Legacy Preamble), HE 프리앰블(HE-Preamble) 및 데이터 필드를 포함하는 PPDU를 생성하는 단계 및 상기 생성된 PPDU를 전송하는 단계를 포함하고, 상기 데이터 필드를 구성하는 전체 서브캐리어의 개수 또는 상기 PPDU 생성 시 이용되는 FFT(Fast Fourier Transform) 크기 값을 상기 파일럿의 총 개수로 나눈 값 보다 작지 않은 최소의 정수 개의 파일럿 패턴들이 정의되고, 상기 데이터 필드의 심볼 별로 상기 파일럿 패턴들 중 소정의 파일럿 패턴이 할당되고, 상기 파일럿 패턴에 의해 상기 파일럿이 매핑되는 서브캐리어의 인덱스가 결정될 수 있다.
