Abstract

다양한 실시예에 따른 무선 통신 시스템에서 단말이 피드백 신호를 전송하는 방법 및 이를 위한 장치가 개시된다. PDSCH (Physical downlink Shared Channel)를 스케줄링하는 제1 신호를 수신하는 단계, 및 상기 제1 신호와 관련된 상기 피드백 신호의 전송 여부를 결정하는 단계를 포함하고, 상기 피드백 신호는 상기 제1 신호가 SPS (semi-persistent scheduling) PDSCH의 활성화 (activation) 또는 해제 (release)에 대한 제어 정보를 포함한 것에 기초하여 상기 PDSCH에 대한 HARQ (Hybrid Automatic Repeat and request) 프로세스가 디스에이블 (disable)인지 여부에 무관하게 전송되는 방법 및 이를 위한 장치를 개시한다.
