Abstract

이종 네트워크 환경에서의 간섭 관리 방법이 개시된다. 본 발명에 따른 기지국의 셀간 간섭 관리 방법의 한 양태는 일부 자원이 천공(puncturing)되는 서브 프레임들에 대한 정보를 단말에게 전송하는 단계와 서브 프레임들에 대한 정보에 기초하여, 대응되는 서브 프레임을 일부 자원을 천공하여 단말에게 전송하는 단계를 포함하여 구성된다. 본 발명에 따른 기지국의 셀간 간섭 관리 방법의 다른 양태는 시스템 정보 전송 용도의 자원을 설정하는 단계와 ABS(Almost Blank Subframe)로 지정된 서브 프레임을 이용하여 시스템 정보를 전송하는 경우 시스템 정보 전송 용도의 자원만을 이용하거나, 시스템 정보 전송 용도의 자원을 우선적으로 이용하여 상기 시스템 정보를 전송하는 단계를 포함하여 구성된다. 따라서, ABS 서브프레임을 이용하여 CRS 등의 중요한 시스템 정보들이 전송되어야만 하는 경우에도 셀간 간섭의 문제를 완화시킬 수 있다.
