Classification: CPC H | IPC H

Claim 12:
13. A method performed by a station (STA) configured to operate in a wireless local area network (WLAN) system supporting a high efficiency (HE) physical layer protocol data unit (PPDU), the method comprising:
setting a first duration field included in a HE signal A (HE-SIG A) field; and
transmitting the HE PPDU comprising (i) the HE-SIG A field and (ii) a medium access control (MAC) header,
wherein the MAC header comprises a second duration field,
wherein the first duration field comprises at least one most significant bit (MSB) and at least one least significant bit (LSB),
wherein the first duration field is set based on a transmission opportunity (TXOP) duration value,
wherein a first value multiplied by a second value relates to the TXOP duration value,
wherein the at least one MSB relates to the first value,
wherein the at least one LSB relates to the second value, and
wherein a bit length of the first duration field is smaller than a bit length of the second duration field.
