Abstract

본 발명은 비직교다중접속 방식 (NOMA)을 지원하는 무선 접속 시스템에서, 다양한 하이브리드 자동재전송 (HARQ) 방법들, 이를 위한 데이터 버퍼링 방법들 및 이를 지원하는 장치들에 관한 것이다. 본 발명의 일 실시예로서 비직교다중접 속 (NOMA) 방식을 지원하는 무선접속시스템에서 제 1 단말이 하이브리드 자동재전 송 (HARQ)을 위한 데이터 버퍼링 방법은, 기지국으로부터 제 1단말 및 제 2단말에 대한 데이터가 NOMA 방식으로 다중화된 데이터를 수신하는 단계와 다중화된 데 이터를 디코딩하는 단계와 제 2 단말에 대한 데이터를 버퍼링하는 단계와 디코딩 결과에 따라 HARQ-ACK 정보를 기지국에 전송하는 단계를 포함할 수 있다.
