Abstract

다수의 주파수 밴드들을 지원하는 시스템에서 부반송파의 간격을 제어하는 장치를 제공한다. 상기 부반송파 간격제어장치는 다수의 주파수 밴드들에 걸쳐 발생하는 간섭을 검출하는 간섭 검출부, 상기 다수의 주파수 밴드들에 관한 부반송파 간격(subcarrier spacing)과 관련된 시스템 파라미터, 예를 들어, RF, FFT 크기, 채널 대역폭 등과 같은 시스템 파라미터를 부반송파 간격 제어부에 제공하는 시스템 파라미터 제공부, 및 상기 시스템 파라미터를 기초로, 상기 검출된 간섭을 줄이도록 상기 부반송파 간격을 제어하는 부반송파 간격 제어부를 포함한다. 다중밴드를 운용하는 시스템에서 각 밴드별로 서로 다른 부반송파 간격을 적용하여 각 밴드에서 발생하는 간섭을 제어할 수 있다.
