摘要： In a wireless frame transmission method by an access point (AP) in a wireless LAN system, according to an embodiment of the present invention, a wireless frame, comprising a signaling field and a data field, is generated in the AP, wherein the signaling field comprises a first signaling field (SIG A field), having first common control information about a plurality of STAs, and a second signaling field (SIG B field) having individual control information for each of the plurality of STAs. The second signaling field comprises a common field, having second common control information about the plurality of STAs, and an individual field following the common field and having individual control information for each of the STAs. An individual field (a first individual field) of the second signaling field being transmitted from a particular 20 MHz band (a first band) can comprise: resource allocation information about one or more first band STAs to which resources are allocated in the first band; and resource allocation information about one or more second band STAs to which resources are allocated from another 20 MHz band (a second band) other than the first band. Therefore, the length of the first individual field can be set to be the same as the length of the individual field (second individual field) of the second signaling field being transmitted from the second band.

摘要： 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.
