Zusammenfassung:The present disclosure relates to a 5G or 6G communication system for supporting higher data rates. Disclosed in the present disclosure is a method performing multi-cell scheduling using downlink control information, for scheduling multi-cell transmissions through a single DCI in a wireless communication system, which comprises the ways of: by a terminal, receiving an instruction on a cell to be scheduled via a time domain resource assignment (TDRA) field in the DCI; distinguishing a multi-cell transmission and single-cell transmission when the terminal receives the TDRA; receiving an instruction on a cell to be scheduled via bitmap information in a DCI field; and utilizing a frequency domain resource allocation (FDRA) field for multi-cell transmissions. 본 개시는 보다 높은 데이터 전송률을 지원하기 위한 5G 또는 6G 통신 시스템에 관련된 것이다. 본 개시는 무선 통신 시스템에서 단일 DCI를 통한 다중 셀 전송을 스케줄링함에 있어, 단말이 DCI 내 TDRA (Time domain resource assignment) 필드를 통해 스케줄링 되는 셀을 지시 받는 방법, 단말이 TDRA를 설정 받을 경우 다중 셀 전송인지 단일 셀 전송인지를 구분하는 방법, DCI 필드 내 비트맵 정보를 통해 스케줄링되는 셀을 지시 받는 방법, 다중 셀 전송을 위해 FDRA (Frequency domain resource allocation) 필드를 이용하는 방법을 개시한다.
