Abstract: A method for performing, by a station (STA) apparatus, uplink (UL) multi-user (MU) transmission in a wireless communication system according to an embodiment of the present invention includes performing carrier sensing on a channel, receiving a trigger frame including information for UL MU transmission and a carrier sense indicator indicating whether a result of the carrier sensing is to be reflected from an access point (AP), and transmitting an UL MU frame through the channel based on the information for UL MU transmission. The UL MU frame is transmitted through the channel based on a result of the carrier sensing if the carrier sense indicator indicates the reflection of a result of the carrier sensing. The UL MU frame is transmitted through the channel regardless of a result of the carries sensing if the carrier sense indicator does not indicate the reflection of a result of the carrier sensing.

Abstract: The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.

Abstract: The present document relates to a method for efficiently performing uplink multi-user transmission in a wireless LAN system and an apparatus therefor. To this end, an access point (AP) may transmit a downlink multi-user frame to a plurality of STAs, receive an uplink frame including an acknowledgement/non-acknowledgement (ACK/NACK) signal for the downlink multi-user frame and an uplink scheduling request signal from at least two STAs among the STAs, transmit a downlink frame including uplink scheduling information to the at least two STAs on the basis of the uplink scheduling request signal, and receive an uplink multi-user frame including data from the at least two STAs in response thereto. Here, an SIG field of the downlink frame preferably comprises an indicator indicating that the downlink frame includes uplink multi-user scheduling information.
