Abstract

무선 통신 시스템에서 단말에 의한 메시지 전송 방법 및 장치가 제공된다. 단말은 기준 셀(reference cell) 및 적어도 하나의 인접 셀(neighbor cell)로부터 각각 포지셔닝 참조 신호(PRS; Positioning Reference Signal)를 수신하고, 상기 기준 셀이 전송하는 PRS의 뮤팅 패턴(muting pattern)을 지시하는 기준 셀 PRS 뮤팅 시퀀스 및 상기 적어도 하나의 인접 셀이 전송하는 PRS의 뮤팅 패턴을 지시하는 인접 셀 PRS 뮤팅 시퀀스를 포함하는 보조 데이터 제공 메시지를 E-SMLC(Enhanced Serving Mobile Location Center)로부터 수신하고, 상기 기준 셀 및 적어도 하나의 인접 셀로부터 수신한 PRS를 기반으로 측정된 참조 신호 시간 차이(RSTD; Reference Signal Time difference)를 상기 E-SMLC로 전송한다.
