Abstract: Disclosed is a method by which an operating station (STA) transmits a signal in a multiple user (MU) scheme in a wireless LAN (WLAN) system. In the present method, the STA configures a wireless frame, which includes a data field for data transmission and a signaling (SIG) field including control information, wherein the SIG field includes a SIG A field, which includes bandwidth information indicating the whole bandwidth having a bandwidth of 2n times that of 20 MHz, and a SIG B field, which includes user specific information. Here, the bandwidth information of the SIG A field additionally indicates whether the whole bandwidth includes one or more 20 MHz bands (null channel), which are not used in the data transmission.

Abstract: A method for transmitting data by a first station (STA) in a wireless local area network (WLAN) system is disclosed. The method includes configuring, as a radio frame for transmission of the data, a high efficiency extended range single user physical protocol data unit (HE ER SU PPDU) in which a high efficiency signal A (HE-SIG-A) field is repeated, and transmitting the configured HE ER SU PPDU to a second STA in a resource unit (RU) of one of a first type and a second type, the first type having a size of 106 tones and the second type having a size of 242 tones. If the HE ER SU PPDU is transmitted in an RU of the first type, the HE ER SU PPDU is transmitted in an RU of the first type at a fixed position in a primary 20-MHz channel.

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.
