Abstract

무선 통신 시스템에서 데이터를 전송하는 방법 및 장치가 제공된다. 기지국은 매크로 노드(macro node)를 통해 PDCCH(physical downlink control channel)을 단말로 전송하고, 상기 매크로 노드와 동일한 셀 ID(identity)를 가지는 적어도 하나의 RRH(radio remote head)를 통해 상기 PDCCH와 시간 영역(time domain)에서 겹치지 않도록 PDSCH(physical downlink shared channel)를 단말로 전송한다. 상기 PDCCH가 할당되는 마지막 OFDM(orthogonal frequency division multiplexing) 심벌과 상기 PDSCH가 할당되는 첫 번째 OFDM 심벌 사이에 시간 갭(time gap)이 설정될 수 있다.
