Abstract
단말의 변조 장치는 상향링크 공유 채널을 위한 PUSCH 신호를 생성하고, 상향링크 제어 채널을 위한 PUCCH 신호를 생성하며, PUSCH 신호 또는 PUCCH 신호를 복조 하기 위한 DMRS 신호를 생성한다. 단말의 변조 장치는 상향링크 프레임의 신호 순서에 따라 PUSCH 신호와 PUCCH 신호 중 하나를 선택하여 선택 신호를 출력하고, 선택 신호에 대해 이산 푸리에 변환을 하여 제1 변환 신호를 생성하며, 제1 변환 신호 및 DMRS 신호 중 하나의 신호를 선택하여 부반송파 매핑 신호를 생성한다. 또한, 변조 장치는 부반송파 매핑 신호를 역고속 푸리에 변환하여 상향링크 프레임의 심볼을 생성하고, 상향링크 프레임의 심볼 동기를 위한 지연 시간만큼 심볼을 지연하여 전송한다.
