1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), a trigger frame from a transmitting STA; and
transmitting, by the receiving STA, a Trigger Based Physical Protocol Data Unit (TB PPDU) through a preset frequency band to the transmitting STA,
wherein the trigger frame includes a common information field and a special user information field,
wherein the common information field includes first to fourth spatial reuse fields,
wherein the special user information field includes fifth and sixth spatial reuse fields,
wherein when the preset frequency band is a 20 MHz band, the first to fourth spatial reuse fields are set to a value of the fifth spatial reuse field,
wherein when the preset frequency band is a 40 MHz band, the first and third spatial reuse fields are set to a value of the fifth spatial reuse field, and the second and fourth spatial reuse fields are set to a value of the sixth spatial reuse field,
wherein when the preset frequency band is an 80 MHz band, the first and second spatial reuse fields are set to a value of the fifth spatial reuse field, and the third and fourth spatial reuse fields are set to a value of the sixth spatial reuse field,
wherein when the preset frequency band is a 160 MHz band, the first and second spatial reuse fields are set to a value of the fifth spatial reuse field, and the third and fourth spatial reuse fields are set to a value of the sixth spatial reuse field, and
wherein when the preset frequency band is a 320 MHz band, the first to fourth spatial reuse fields are set to a smaller value among the values of the fifth and sixth spatial reuse fields.
