Abstract

무선 통신 시스템에서 참조 신호 시퀀스 생성 방법 및 장치가 제공된다. 단말은 기지국으로부터 셀 특정(cell-specific) 시퀀스 홉핑(sequence hopping) 파라미터를 수신하고, 상기 기지국으로부터 상기 단말에 특정된 단말 특정(UE-specific) 시퀀스 그룹 홉핑(SGH; Sequence Group Hopping) 파라미터를 수신하고, 상기 셀 특정 시퀀스 홉핑 파라미터 및 상기 단말 특정 시퀀스 그룹 홉핑 파라미터를 기반으로 각 슬롯(slot) 단위로 결정된 기본 시퀀스(base sequence)의 기본 시퀀스 번호(base sequence number)를 기반으로 참조 신호 시퀀스를 생성한다. 이때 상기 단말 특정 시퀀스 그룹 홉핑 파라미터에 의해 지시되는 상기 기본 시퀀스 번호의 시퀀스 홉핑 적용 여부는 상기 셀 특정 시퀀스 홉핑 파라미터에 의해 지시되는 상기 기본 시퀀스 번호의 시퀀스 홉핑 적용 여부에 우선(override)한다.
