Abstract

본 발명은 무선 통신 시스템에서 V2X(vehicle-to-X) 단말에 의해 수행되는 기존의 TTI(legacy transmission time interval; L-TTI)에 비해 상대적으로 짧은 TTI(short transmission time interval; S-TTI) 기반의 V2X 통신 수행 방법에 있어서, DMRS(demodulation reference signal) 시퀀스 생성에 사용되는 정보 및 채널 스크램블링에 사용되는 정보를 결정하고 및 상기 결정에 기초하여 상기 S-TTI 기반의 V2X 통신을 수행하되, 상기 L-TTI는 복수의 상기 S-TTI에 대응되는 것을 특징으로 하는 방법을 제공한다.
