Abstract

무선 통신 시스템에서 펨토 기지국의 인터 워킹 신호(IWS; Inter-Working Signal) 전송 방법 및 장치가 제공된다. 펨토 기지국은 상기 펨토 기지국이 동작하는 주파수 대역에 관한 정보를 포함하는 프리앰블(preamble)의 시퀀스를 생성하고, 상기 프리앰블의 시퀀스를 포함하는 인터 워킹 신호를 주파수 영역의 복수의 부반송파에 맵핑하고, 상기 인터 워킹 신호를 상기 복수의 부반송파를 통해 단말로 전송한다. 상기 인터 워킹 신호는 시간 영역에서 하나의 동일한 OFDM(Orthogonal Frequency Division Multiplexing) 심벌 상에 위치하는 복수의 부반송파에 맵핑될 수 있고, 또는 미리 지정된 복수의 자원 유닛(RU; Resource Unit)에 맵핑될 수 있다.
