Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links including a first link can transmit a request frame to a first AP of an AP MLD through a first STA (station), wherein the request frame includes an information field for requesting every element included in an element set designated for a second link. The MLD can, on the basis of the request frame, receive every element included in the element set designated for the second link.

Abstract: In a wireless local area network (LAN) system, a transmission station (STA) may transmit, to a receiving STA, a PHY protocol data unit (PPDU) including a first redundancy version of transmission data. On the basis of whether an acknowledgement (ACK) or negative ACK (NACK) frame is received within a threshold time, the transmission STA may determine a second redundancy version of the transmission data to be retransmitted.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: According to various embodiments, a multi-link device (MLD) operating in multiple links including a first link may transmit, through a first station (STA) and to a first AP of an AP multi-link device, a request frame including an information field for requesting at least one element related to a second link. The multi-link device may receive at least one element related to the second link on the basis of the request frame.

Abstract: In a wireless local area network system, a multi-link device (MLD) may transmit a multi-link element including a number-of-links field and a link present field indicating whether the number-of-links field exists. The multi-link element further includes a multi-link control field, a common information field, and a link information field. The number-of-links field may be included in the multi-link control field.

Abstract: In a wireless local area network (LAN) system, a first station (STA) may check the transfer failure of a first acknowledgement (ACK) signal for a first frame, the signal being received through a first link. The first STA may transmit report information related to the transfer failure of the first ACK signal to a second STA through a second link. Here, the report information may include identification information associated with the first link. The first STA may receive a second frame from the second STA through the first link. The first STA may transmit a second ACK signal for the second frame to the second STA through the first link on a narrowband.

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).

Abstract: A method performed at a sharing access point (AP) of a wireless local area network (LAN) system may comprise the steps of: transmitting, to a first station (STA), a first measurement notification frame requesting measurement of a received signal strength indicator (RSSI); transmitting, to the first STA, a first measurement request frame for requesting a first path loss value which is path loss information of an overlapping basic service set (OBSS) AP andthe first STA and an acceptable receiver interference level (ARIL) value; receiving, from the first STA, a first measurement report frame including the first path loss and a first ARIL value of the first STA; and transmitting, to the first STA, first data.
