Abstract
An example according to the present specification relates to a technique for identifying a wireless LAN (WLAN) packet. An NGV PPDU may include a first legacy control field and a second legacy control field. The second legacy control field may be used to identify a type of a PPDU. The first legacy control field may be received through a first symbol, and the second legacy control field may be received through a second symbol. The first legacy control field and the second legacy control field may include identical bit information.

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.
A station in a wireless local area network (WLAN) system, the station comprising:
- a memory configured to store a received Physical Protocol Data Unit (PPDU);
- and
- a processor configured to control the memory:
- wherein the processor is further configured to:
- receive 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
- decode 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.
