    Abstract: Disclosed herein is a method for allowing a first device to be connected to a second device in a wireless communication system. The method includes performing a procedure for setting an advertising packet for providing a transport discovery service (TDS) and transmitting the set advertising packet to the second device, wherein the advertising packet comprises at least one advertising (AD) structure field, and one of the at least one AD structure field comprises a first length field, an AD type field indicating a type of data for providing the TDS, and an AD data field comprising TDS data for providing the TDS.

    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: An AP downlink multi-user transmission method in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: generating a DL MU PPDU, wherein the DL MU PPDU comprises resource allocation information for uplink MU transmission by a station (STA); transmitting the DL MU PPDU to the STA; and, on the basis of the DL MU PPDU, receiving a UL MU PPDU generated by the STA, wherein the UL MU PPDU comprises a first part having a first IDFT/DFT cycle, and a second part having a second IDFT/DFT cycle that is four times the first IDFT/DFT cycle, wherein the first part may be received through at least one 20 MHz channel in a position corresponding to a frequency resource indicated by the resource allocation information, and the second part may be received by using the frequency resource indicated by the resource allocation information.

    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.
