Abstract

본 명세서는 OFDMA 시스템에서 자원을 스케줄링하기 위한 채널추정 기준신호(Channel Estimation Reference Signal)의 주기적 전송과 비주기 전송 사이의 스위칭 방법 및 그를 이용한 기준신호 송수신 장치에 관한 것이다. 채널추정 기준신호의 주기적 전송과 비주기적 전송을 스케줄링하기 위하여 일정한 형식의 전송 지시자를 사용하며, 전송 지시자는 1비트 이상의 주기/비주기 구분 지시자를 포함한다. 본 실시예를 이용하면, 채널추정 기준신호의 비주기적 전송 및 주기적 전송을 혼합하여 수행하면서도, 단말간 또는 셀간 간섭을 최소화할 수 있고, 기준신호의 전송 효율을 향상시킬 수 있다.
