Abstract

본 발명은 펨토셀 기지국의 동기화 방법 및 이를 이용한 펨토셀 기지국에 관한 것이다. 보다 상세하게는 실내 또는 기존 셀의 음영 지역을 위해 펨토셀을 도입하면서 펨토셀 기지국이 프리앰블 신호를 수신하고 이를 기준으로 하여 하향 링크 동기를 맞추고, 펨토셀 기지국이 매크로셀 기지국에 레인징 신호를 송신하고 그에 따라 상향 링크 동기 정보를 수신함으로써 단말의 상향 링크 동기를 확보하여, 매크로셀과 동일한 주파수 대역의 서로 다른 부반송파 또는 같은 부반송파를 사용하면서도 부반송파 간의 직교성을 유지하여 원치 않는 신호의 간섭을 배제할 수 있는 펨토셀 기지국의 동기화 방법 및 이를 이용한 펨토셀 기지국에 관한 것이다. 이를 위해 본 발명은 매크로셀 내에 펨토셀(Femtocell)이 존재하는 OFDMA(Orthogonal Frequency Division Multiple Access) 통신 시스템에서 펨토셀 기지국이 매크로셀 기지국으로부터 프리앰블(preamble) 신호를 수신하면, 상기 펨토셀 기지국이 상기 프리앰블 신호에 시간 동기를 맞추어서 상기 펨토셀에 속한 단말에 심볼을 송신함으로써 펨토셀 기지국의 시간 동기를 확보하는 펨토셀 기지국의 동기화 방법을 제공한다.
