1. A method for transmitting a New Generation Vehicular (NGV) frame in a wireless local area network (WLAN) system, the method comprising:
generating, by a transmitting device, the NGV frame; and
transmitting, by the transmitting device, the NGV frame to a receiving device through a first band,
wherein the NGV frame includes Legacy-Short Training Field (L-STF), Legacy-Long Training Field (L-LTF), Legacy-Signal (L-SIG), Repeated Legacy (RL)-SIG, NGV-SIG, NGV-STF, NGV-LTF, and NGV-Data,
wherein the L-SIG, the RL-SIG and the NGV-SIG are duplicated in units of a second band and transmitted through the first band,
wherein the NGV-STF and the NGV-LTF are transmitted through a full band of the first band,
wherein a subcarrier frequency spacing of the NGV-STF, the NGV-LTF and the NGV-Data is half of a subcarrier frequency spacing of a Very High Throughput (VHT) physical (PHY),
wherein the first band is a 20 MHz band, and
wherein the second band is a 10 MHz band.
