Abstract
Disclosed herein is an operating method of a station (STA) in a wireless LAN (WLAN) system. The method includes receiving a downlink (DL) physical protocol data unit (PPDU) and sending an uplink (UL) PPDU as a response to the DL PPDU. The DL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a first high efficiency (HE) control field. The UL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a second high efficiency (HE) control field. The each of the first and second HE control fields corresponds to an HT control field and comprises a plurality of aggregated HE control subfield. The HT control field includes VHT subfield value set to “1” and HE subfield value set to “1”.
