    Abstract: A method for beamforming training and a device using the same are provided. A station (STA) receives a beacon frame from an access point (AP) during a beacon transmission interval (BTI). The beacon frame includes information on a sector sweep (SSW) frame type used in at least one of a plurality of SSW slots. During association beamforming training (A-BFT), the STA transmits the SSW frame according to the SSW frame type from an SSW slot, among a plurality of SSW slots, having succeeded in a random backoff.

    Abstract: 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.

    Abstract: A method for transmitting a frame on the basis of multiple channelized channels in a wireless LAN system according to one embodiment of the present specification comprises the steps of: configuring, by a first wireless terminal, a control mode physical protocol data unit (PPDU) including encoding information on a channel bandwidth formed on the basis of first to sixth channels sequentially arranged on the frequency axis, wherein five bits are assigned for the encoding information and each of the first to sixth channels has a bandwidth of 2.16 GHz; and transmitting, by the first wireless terminal, the control mode PPDU to a second wireless terminal on the basis of the channel bandwidth.
