Classification: CPC H | IPC H

Claim 8:
9. A method performed in a wireless local area network (WLAN) system, the method performed by a transmitting station (STA) and comprising:
configuring a Next Generation V2X Physical Protocol Data Unit (NGV PPDU),
wherein the NGV PPDU includes a preamble, a data field contiguous to the preamble, and a midamble contiguous to the data field,
wherein the preamble includes a legacy signal (L-SIG) field, a repeated signal field in which the L-SIG field is repeated, and an NGV signal field including control information for the NGV PPDU,
wherein the NGV signal field includes 1-bit information related to a format of the midamble,
wherein the midamble is configured based on one of a long training field (LTF) sequence of a first interval and an LTF sequence of a second interval,
wherein the format of the midamble is determined as one of a first format related to the LTF sequence of the first interval and a second format related to the LTF sequence of the second interval;
wherein the symbol of the midamble of the first format includes an LTF signal configured based on the LTF sequence of the first interval and a guard interval (GI) related to the LTF signal,
wherein a duration of the LTF signal is 3.2 μs, a duration of the GI is 1.6 μs, and a symbol duration of the midamble of the first format is 4.8 μs; and
transmitting the NGV PPDU.
