Technique for transmitting and receiving frame in wireless communication system

A transmitting station (STA) for transmitting a frame in a Wireless Local Area Network (WLAN) system, the transmitting STA comprising:

• a transceiver transmitting and receiving radio signals;
• and
• a processor being operatively connected to the transceiver,
• wherein the processor is configured to:
• generate a Next Generation Vehicular network (NGV) Physical Protocol Data Unit (PPDU) including a legacy control field, an NGV control field, and an NGV data field, and
• transmit the NGV PPDU, wherein a bandwidth of the NGV PPDU is 20 MHz, and the NGV PPDU is transmitted based on frequency spacing of 156.25 kHz, and
• wherein the NGV PPDU is transmitted based on a guard region having a first sub-carrier index range, a Direct Current (DC) region having a second sub-carrier index range, and a data and pilot region having a third sub-carrier index range.
