Abstract

무선 통신 시스템에서 상향링크 송신 전력을 설정하는 방법 및 단말 장치가 제공된다. 단말은 지원 가능한 다수의 서빙셀들에 대한 시간 정렬 그룹(TAG)에 대한 정보를 획득하여 TAG들을 구성하고, 상기 TAG들에서 상향링크 전송을 위한 서브프레임 n과 서브프레임 n+1에 대하여 중첩 구간이 존재하는지 확인하여, 상기 확인된 중첩(overlap) 구간에서의 미리 구성된 단말의 최대 전송 전력(configured maximum output power PCMAX)을 초과하지 않는 범위내에서 상향링크 송신 전력(PCMAX)을 스케일링하도록, 상향링크 송신 전력을 설정한다. 여기서, 상기 상향링크 송신 전력은 상기 TAG들에 포함되는 다수의 서빙셀들에 대한 최대 송신전력을 고려함을 포함한다.
