Abstract:
(EN) A method by which a first station (STA) transmits a signal by using repetitive modulation in a wireless LAN system is disclosed in the present invention. The first STA modulates preamble information and/or data field information of a transmitting wireless frame. In the modulation: the preamble information and/or the data field information are modulated by using one of BPSK, QPSK, and 16-QAM; and respective modulated symbols are repetitively mapped to two or more sub-carriers, wherein the number of repetitions of the respective modulated symbols is at least 3.
(FR) La présente invention concerne un procédé selon lequel une première station (STA) transmet un signal au moyen d'une modulation répétitive dans un système de réseau local (LAN) sans fil. La première station (STA) module l'information de préambule et/ou l'information de champ de données d'une trame sans fil de transmission. Dans la modulation: l'information de préambule et/ou l'information de champ de données sont modulées au moyen d'une parmi des modulations BPSK, QPSK et 16-QAM; et des symboles modulés respectifs sont mis en correspondance de manière répétitive avec au moins deux sous-porteuses, le nombre de répétitions des symboles modulés respectifs étant au moins 3.
(KO) 본 문서에서는 무선랜 시스템에서 제 1 스테이션(STA)이 반복 변조방식을 이용하여 신호를 전송하는 방법을 개시한다. 제 1 STA이 전송하는 무선 프레임의 프리엠블 정보 및 데이터 필드 정보 중 하나 이상을 변조하되, 상기 변조는, 상기 프리엠블 정보 및 상기 데이터 필드 정보 중 하나 이상을 BPSK, QPSK 및 16-QAM 방식 중 하나를 이용하여 변조한 후, 상기 변조된 심볼들 각각을 2 이상의 서브캐리어에 반복 맵핑하되, 상기 변조된 심볼들 각각이 반복되는 횟수는 3이상인 변조이다.
