1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), a trigger frame soliciting a Trigger Based Physical Protocol Data Unit (TB PPDU) from a transmitting STA; and
transmitting, by the receiving STA, the TB PPDU 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 an uplink (UL) spatial reuse field comprising first to fourth spatial reuse subfields,
wherein the special user information field includes first and second extreme high throughput (EHT) spatial reuse subfields,
wherein based on a bandwidth of the TB PPDU being 20 MHz, each of the first to fourth spatial reuse subfields is set to a value of the first EHT spatial reuse subfield,
wherein based on the bandwidth of the TB PPDU being 40 MHz, the first and third spatial reuse subfields are set to the value of the first EHT spatial reuse subfield, and the second and fourth spatial reuse subfields are set to a value of the second EHT spatial reuse subfield,
wherein based on the bandwidth of the TB PPDU being 80 MHz or 160 MHz, the first and second spatial reuse subfields are set to the value of the first EHT spatial reuse subfield, and the third and fourth spatial reuse subfields are set to the value of the second EHT spatial reuse subfield, and
wherein based on the bandwidth of the TB PPDU being 320 MHz, each of the first to fourth spatial reuse subfields is set to a smaller of the values of the first and second EHT spatial reuse subfields.
