摘要： A method and apparatus for transmitting frames having a signaling field (SIG) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA. Here, the second part includes a first signaling field (HE-SIG A) for common control information and a second signaling field (HE-SIG B) for signaling information comprising user specific control information. Regarding the second signaling field, independent signaling information for the second signaling field (HE-SIG B) is to be transmitted for each 20 MHz bandwidth within a first 40 MHz bandwidth. And the signaling information of the first 40 MHz bandwidth is duplicated in a second 40 MHz bandwidth, when the frame is to be transmitted in a bandwidth equals to or greater than 80 MHz. STA transmits this prepared frame to one or more STAs.

摘要： Disclosed is a method for transmitting a preamble in a wireless LAN system, and a station device for performing the same. To this end, a station for transmitting a preamble configures a wireless frame including a first type terminal frame portion, and a second type terminal frame portion. The first type terminal frame portion includes a first type terminal preamble including a first type terminal short training field (STF) and a first type terminal long training field (LTF), and the second type terminal frame portion includes a second type terminal preamble including a second type terminal SFT and a second type terminal LTF. Here, the station configures the second type terminal preamble by allocating sequence components at an interval of an integer number of tones in a frequency domain and transmits the configured wireless frame to another station.

摘要： The present document is for flexibly resource allocation in a wireless LAN system. To this end, an STA prepares resource allocation information in which data is to be transmitted to a plurality of STAs by using an orthogonal frequency divisional multiple access (OFDMA) scheme or a multiple user MIMO (MU-MIMO) scheme, and transmits the data to the plurality of STAs according to the resource allocation information. The resource allocation information preferably includes a group ID indicating the plurality of STAs, a resource allocation bitmap having a format in common with the plurality of STAs, resource allocation information for each of the plurality of STAs and resource allocation sequence information indicating a resource allocation order of the STAs in the group.
