Abstract

무선 통신 시스템에서 동기화 신호(synchronization signal)를 전송하는 방법 및 장치가 제공된다. 기지국은 매크로 노드(macro node)를 통하여 1차 동기화 신호(PSS; primary synchronization signal) 및 2차 동기화 신호(SSS; secondary synchronization signal)를 단말로 전송하고, 상기 매크로 노드와 동일한 셀 ID(identity)를 가지는 적어도 하나의 RRH(radio remote head)를 통하여 3차 동기화 신호(TSS; third synchronization signal)를 상기 단말로 전송한다. 상기 단말은 상기 PSS, SSS 및 TSS 중 적어도 하나를 기반으로 동기화를 수행한다.
