Abstract

본 명세서의 일 실시예에 따른 무선 통신 시스템에서 단말이 동작하는 방법은 기지국으로부터 둘 이상의 코드워드들 각각에 대한 MCS(Modulation and Coding Scheme) 정보를 수신하는 단계; MCS 정보에 기초하여 PTRS(Phase Tracking Reference Signal) 안테나 포트가 매핑된 DMRS(DeModulation Reference Signal) 안테나 포트를 결정하는 단계; 및 DMRS 안테나 포트에 기초하여 PTRS를 수신하는 단계를 포함하되, DMRS 안테나 포트는 둘 이상의 코드워드들 중 더 높은 MCS를 갖는 코드워드에 포함되는 하나 이상의 DMRS 안테나 포트들 중 가장 낮은 인덱스를 갖는 DMRS 안테나 포트로 결정될 수 있다.
