Abstract:
A method for transmitting data in wireless LAN may include the step of: receiving a non-target RTS frame from a second STA by a first STA, wherein the non-target RTS frame includes an RA field indicating a third STA; when the first STA does not receive a non-target CTS frame after a predetermined time and tries to transmit a data frame to an AP, transmitting an RTS frame to the AP by the first STA, wherein the non-target CTS frame is a response frame to the non-target RTS frame; and when the first STA has received a CTS frame in response to the RTS frame from the AP, transmitting the data frame to the AP by the first STA.
Abstract:
Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a wide band from a transmission STA, and decodes the PPDU. The wide band is a 320/160+160 MHz band configured from a first band and a second band. When the first band is an 80 MHz band in which puncturing is performed in units of 20 MHz, the first band includes a first RU which is an aggregate of a 484RU and a 242RU. The second band is a 240 MHz band excluding the first band in the wide band, and includes a second RU which is an aggregate of three 996 RUs. The PPDU includes a control field and a data field. The data field is received via a first multi-RU which is an aggregate of the first and second RUs.
Abstract:
In a wireless local area network (LAN) system, a transmitting station (STA) may transmit a peer-to-peer (P2P) transmission request frame to an access point (AP). The transmitting STA may receive a P2P transmission response frame from the AP. The transmitting STA may receive a trigger frame from the AP. The trigger frame may include information related to whether same is for an uplink, P2P transmission or both an uplink and P2P transmission. The transmitting STA may transmit data to a receiving STA. The transmitting STA and the receiving STA may be non-AP STAs. The transmitting STA may transmit a null data packet announcement (NDPA) frame and a null data packet (NDP) frame to the receiving STA. The transmitting STA may receive, from the receiving STA, a feedback frame including state information for the channel between the transmitting STA and the receiving STA.
Abstract:
A method and apparatus for identifying change sequence information in a wireless LAN system are proposed. In detail, an STA receives a DTIM beacon frame and a beacon frame from a first AP. The STA decodes the DTIM beacon frame in a first awake state and decodes the beacon frame in a second awake state. Both the DTIM beacon frame and the beacon frame include a CUF and a CSN. When a significant update of a second AP occurs, a value of the CUF is changed from 0 to 1 until transmission of a next DTIM beacon frame, the value of the CUF is changed from 1 to 0 after the transmission of the next DTIM beacon frame, and the CSN includes updated information. The updated information is decoded in the second awake state regardless of the value of the CUF.
Abstract:
A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).

If a significant update on a second transmission STA occurs, a value of the notification method mode field is set to 1, and the management frame includes significant update information of the second transmission STA.
