Abstract: 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.

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.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for accessing a channel in a wireless LAN system. According to one embodiment of the present invention, a method for performing channel access by a station (STA) of a wireless communication system comprises: a step of receiving, from an access point (AP), information about the time window which does not allow channel access of a traffic indication map (TIM) mode STA; and a step of performing channel access based on the time window. In the event that the STA is a non-TIM mode STA, the channel access is performed in the time window. In the event that the STA is a TIM mode STA, the channel access is performed in the time interval indicated by the TIM, excluding the time window.

Abstract: A wireless communication system is disclosed. Specifically a channelization method in a whitespace band and an apparatus for the same are disclosed. A method for providing whitespace operation information includes transmitting by a first station (STA) to a second STA a frame including a TV whitespace high throughput (TVHT) operation information field. The TVHT operation information field includes primary channel number channel width channel center frequency segment 0 and channel center frequency segment 1 subfields. A channel center frequency of frequency segment 0 or frequency segment 1 is determined based on a channel start frequency. The channel start frequency is determined as a function of a TV channel index corresponding to the frequency segment 0 or a TV channel index corresponding to the frequency segment 1.
