Abstract

본 발명은 이종 셀간 간섭조정정보의 전송장치 및 방법에 관한 것이다. 이러한 본 명세서는 시분할 다중화에 기반하여 기지국의 동기신호의 전송이 예정된 서브프레임이, 이종 기지국에 간섭을 일으키지 않도록 상기 동기신호의 전송전력이 감소하는 서브프레임(ABS)인지 아닌지를 지시하는 추가 ABS 패턴을 포함하는 무선 네트워크 정보를 수신하는 신호 수신부; 상기 이종 기지국으로부터 수신되는 신호를 측정하는 측정부, 및 상기 측정된 신호 및 상기 추가 ABS 패턴에 기반하여, 상기 동기신호의 전송전력을 조정하는 전력조정부를 포함하는 기지국을 개시한다. 본 발명에 따르면 이종셀들 상호간에 발생하는 동기신호간 간섭이 줄어들고, 펨토 셀의 멤버쉽이 없는 휴지 상태의 단말이 접근 가능한 셀 검색 및 셀 선택에서의 오류가 줄어들 수 있다.
