1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving a Next Generation Vehicular network (NGV) Physical Protocol Data Unit (PPDU) including a legacy training field, a first legacy control field, a second legacy control field, an NGV control field, and an NGV data field; and
decoding the NGV PPDU, wherein the NGV PPDU is received through a 5.9 GHz band based on a frequency spacing of 156.25 kHz,
wherein the first legacy control field is received through a first symbol, the second legacy control field is received through a second symbol, and the first symbol is contiguous to the second symbol, and
wherein the first legacy control field and the second legacy control field include same bit information.
