Abstract

본 발명에서는 캐리어 병합(Carrier Aggregation/Multiple Cells)을 지원하는 무선 접속 시스템에서 데이터 송수신 방법 및 이를 위한 기지국이 개시된다. 구체적으로, 단말에 설정된 복수의 셀 중 제1 셀의 상향링크-하향링크 구성(uplink-downlink configuration)에 따라 제1 셀을 통해 제2 셀에 대한 크로스 셀 스케줄링을 수행하는 중에, 기지국으로부터 제1 셀의 PDCCH(Physical Downlink Control Channel)을 통해 상향링크 자원 할당 정보임을 지시하는 플래그 값으로 설정된 자원 할당 정보를 수신하는 단계, 제2 셀의 상향링크-하향링크 구성에 기초하여 상향링크 전송 타이밍이 정의되지 않은 서브프레임 시점에서 자원 할당 정보를 수신하는 경우, 자원 할당 정보가 하향링크 자원 할당 정보라고 판단하는 단계, 하향링크 자원 할당 정보에 따라 기지국으로부터 제2 셀의 PDSCH(Physical Downlink Shared Channel)을 통해 상향링크 자원 할당 정보를 수신하는 단계 및 상향링크 자원 할당 정보에 따라 제2 셀의 PUSCH(Physical Uplink Shared Channel)을 통해 기지국에 상향링크 데이터를 전송하는 단계를 포함한다.
