Claim:
1. A method for transmitting an uplink frame to an Access Point (AP) by a Station (STA) in a Wireless Local Area Network (WLAN) system, the method comprising: receiving first transmission power control information and second transmission power control information from the AP; if a type related to the uplink frame is a first type, determining a maximum transmission power based on the first transmission power control information, and if the type related to the uplink frame is a second type, determining a maximum transmission power based on the second transmission power control information; and transmitting the uplink frame based on the determined maximum transmission power, wherein the first type and the second type correspond to different access schemes for uplink transmission, and wherein if the type related to the uplink frame is the second type, transmission of the STA and transmissions of one or more other STAs are performed simultaneously on one same channel in a first region of the uplink frame, and transmission of the STA on one subchannel within the one channel and transmissions of the one or more other STAs on one or more different subchannels within the one channel are performed simultaneously in a second region of the uplink frame.
