1. A method performed in a Wireless Local Area Network (WLAN) system, the method comprising:
generating, by a station (STA), a next generation V2X (NGV) physical protocol data unit (PPDU),
wherein the NGV PPDU comprises a first legacy control field, a second legacy control field in which the first legacy control field is repeated, a first NGV control field, a second NGV control field in which the first NGV control field is repeated, an NGV short training field (STF), and an NGV long training field (LTF),
wherein the second legacy control field is contiguous to the first legacy control field, the first NGV control field is contiguous to the second legacy control field, and the second NGV control field is contiguous to the first NGV control field,
wherein the first and second NGV control fields comprise control information required for interpreting the NGV PPDU,
wherein the control information includes 1-bit information related to a format of the NGV-LTF, and
wherein the control information further includes (i) 1-bit information related to a bandwidth and (ii) 4-bit information related to modulation and coding scheme (MCS); and
transmitting, by the STA, the NGV PPDU.
