1. A method performed by a station (STA) in a wireless local area network (WLAN) system, the method comprising:
receiving a Next Generation V2X Physical Protocol Data Unit (NGV PPDU), wherein the NGV PPDU includes a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field being contiguous to the L-SIG field, an NGV signal (NGV-SIG) field being contiguous to the RL-SIG field, a repeated NGV signal (RNGV-SIG) field being contiguous to the NGV-SIG field, an NGV Long Training Field (NGV-LTF), a data field, and at least one midamble,
wherein the RL-SIG field is a repeat of the L-SIG field, and the RNGV-SIG field is a repeat of the NGV-SIG field,
wherein the NGV-SIG field includes a first field related to a Physical version, a second field related to a periodicity of the at least one midamble, and a third field related to a format of the NGV-LTF,
wherein the NGV PPDU has a bandwidth of 10 MHz,
wherein the third field is set to a first value based on the NGV-LTF being configured based on an NGV-LTF-1x sequence,
wherein the third field is set to a second value based on the NGV-LTF being configured based on an NGV-LTF-2x sequence,
wherein the NGV-LTF-1x sequence is defined as {1, 0, 1, 0, −1, 0, 1, 0, −1, 0, −1, 0, 1, 0, 1, 0, 1, 0, −1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, −1, 0, 1, 0, −1, 0, −1, 0, −1, 0, −1, 0, −1, 0, 1, 0, −1, 0, −1, 0, −1, 0, 1, 0, 1, 0, −1},
wherein the NGV-LTF-2x sequence is defined as {1, 1, 1, 1, −1, −1, 1, 1, −1, 1, −1, 1, 1, 1, 1, 1, 1, −1, −1, 1, 1, −1, 1, −1, 1, 1, 1, 1, 0, 1, −1, −1, 1, 1, −1, 1, −1, 1, −1, −1, −1, −1, −1, 1, 1, −1, −1, 1, −1, 1, −1, 1, 1, 1, 1, −1, −1},
wherein a symbol related to the NGV-LTF-1x sequence includes a Guard Interval (GI) having a length of 1.6 μs, and a duration of the symbol related to the NGV-LTF-1x sequence has a length of 4.8 μs; and
decoding the NGV PPDU based on the NGV-SIG field.
