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, 상기 S-TTI 기반의 V2X 통신에 대한 채널 번잡 비율(channel busy ratio; CBR) 또는 채널 점유 비율(channel occupancy ratio; CR)을 측정하고 및 측정된 상기 CBR 또는 측정된 상기 CR에 기초하여, 상기 S-TTI 기반의 V2X 통신을 수행하되, 상기 S-TTI는 가변적인 길이를 가지는 것을 특징으로 하는 방법을 제공한다.
