Abstract: The present specification proposes a signal processing method for changing an operating mode for configuring a physical-layer protocol data unit (PPDU). Specifically, a first station receives, from a second station, first indication information and second indication information, which indicate a change of an operating mode indicating a number of spatial streams and a channel bandwidth which are supported by the second station. The first station configures a PPDU for the second station using last received indication information of the first indication information and the second indication information. Here, the first indication information is received through an operating mode indication (OMI) field, the second indication information is received through an operating mode notification (OMN) field, and the OMI field and the OMN field are not received through the same PPDU.

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: The present document relates to a method for transmitting an acknowledgment/negative-acknowledgment (ACK/NACK) signal for data transmitted from a plurality of stations (STAs) by an access point (AP) in a wireless LAN (WLAN) system and an apparatus therefor. To this end, the AP transmits a trigger frame to the plurality of STAs, receives data transmitted from the plurality of STAs in response to the trigger frame, and transmits and ACK/ANCK signal for the data received from the plurality of STAs. In this process, when all the data received from the plurality of STAs have been successfully received, the ACK/NACK signal may be transmitted not using a block ACK frame but using an ACK frame.

Abstract: Disclosed are a method and a device for allocating wireless resources in bandwidths of different sizes in a wireless LAN. The method for allocating wireless resources in bandwidths of different sizes in a wireless LAN may comprise steps in which: an AP determines a first resource unit to be allocated to an STA in a first bandwidth; and the AP schedules the first resource unit for the STA, wherein the allocation starting position of the first resource unit allocated in the first bandwidth is configured the same as the allocation starting position of a second resource unit allocated in a second bandwidth, and the allocation starting position of a first guard tone adjacent to the first resource unit may be configured differently from the allocation starting position of a second guard tone adjacent to the second resource unit on the basis of tone shifting.
