Abstract
The present disclosure relates to a method and apparatus for uplink channel access in a High Efficiency WLAN (HEW). According to one aspect, a method for transmitting an uplink frame by a station (STA) to an access point (AP) in a wireless local area network may be provided. The method may include receiving from the AP a trigger frame for eliciting an uplink transmission from the STA, transmitting to the AP the uplink frame according to a type of the trigger frame, wherein when the uplink frame is transmitted in an uplink multiple user (MU) transmission, the uplink frame includes a padding added by the STA such that transmissions from a plurality of STAs including the STA in the uplink MU transmission end at a same time indicated by the trigger frame, and receiving from the AP a frame in response to the uplink MU transmission a predetermined time after an end of the uplink MU transmission.
