Abstract

본 발명은 협대역 사물인터넷(NB-IoT)을 지원하는 무선 접속 시스템에서 동기 신호를 생성하는 방법, 송수신하는 방법 및 장치들을 제공한다. 본 발명의 실시예로서 협대역 사물인터넷(NB-IoT)를 지원하는 무선 접속 시스템에서 기지국이 협대역 부동기신호(N-SSS)를 전송하는 방법은, N-SSS를 생성하기 위해 크기 M인 제1시퀀스를 생성하는 단계와 N-SSS를 생성하기 위해 크기 M인 제2시퀀스를 생성하는 단계와 제1시퀀스 및 제2시퀀스를 이용하여 N-SSS를 생성하는 단계와 N-SSS를 N개의 OFDM 심볼을 통해 전송하는 단계를 포함할 수 있다. 이때, NB-IoT를 지원하는 무선 접속 시스템에서 사용하는 대역폭의 크기는 1 물리 자원 블록(PRB)의 크기이고, 1 PRB는 주파수 영역에서 12개의 서브캐리어로 구성될 수 있다.
