The BA frame may include a first association identifier (AID) information field and a second AID information field. The first AID information field may include a first AID field related to an AID of the transmission MLD and an ACK information field regarding the data. The second AID information field may include a second AID field and a power state information field related to whether the plurality of reception STAs are in an awake state or in a doze state, on the basis of the second AID field having a first value.

Transmission of power state information for multi-link device

A transmitting STA can directly communicate with a receiving STA in a wireless local area network (wireless LAN) system. The transmitting STA can transmit, to an AP, a request signal for a P2P transmission at a determined time or a random time and, when a trigger frame is received from the AP, the transmitting STA can perform P2P communication with a receiving STA on the basis of the trigger frame.

In the first burst, the transmitting STA may receive, from the first receiving STA, a first feedback frame comprising first channel information between the transmitting STA and the first receiving STA, and, from the second receiving STA, a second feedback frame comprising channel information between the transmitting STA and the second receiving STA. In the second burst, the transmitting STA may receive a second sounding signal from the first receiving STA. In the second burst, the transmitting STA may receive, from the second receiving STA, a third feedback frame comprising channel information between the first receiving STA and the second receiving STA.

In a wireless local area network (LAN) system, a transmission MLD may include a first station (STA) and a second STA, which operate in a first link and a second link, respectively. The transmission MLD may transmit, to a reception MLD, a connection request frame including capability information related to whether a restricted basic service set (BSS) mode is supported and information related to use of the restricted BSS mode. The information related to the use of the restricted BSS mode may include first information related to an STA (among STAs in the transmission MLD) which operating in the restricted BSS mode, in which monitoring for signal reception (by the STA operating in the restricted BSS from an STA not operating in the restricted BSS mode) is performed based on acquisition of information indicating reception of a signal. The transmission MLD may receive a connection response frame from the reception MLD.

In a Wireless Local Area Network system, a reception device can receive information about link deactivation, and deactivate a link. The proposed method includes receiving a physical protocol data unit (PPDU) including a first control field in a first link. In the method, the first control field may include information related to disablement of the first link and information on a time point at which the first link is disabled. The proposed method further includes disabling the first link based on the first control field.
