Abstract: In a wireless local area network system, a receiving device may receive a Block Acknowledgment Request (BAR) frame including information related to a link for which an ACK is requested, and transmit a Block ACK (BA) frame on the basis of the BAR frame. The receiving device is a Multi-Link Device (MLD), which supports communication over multiple links. Each link of the multiple links can be configured based on 2.4 GHz band, 5 GHz band, and/or 6 GHz band defined in a conventional wireless local area network system.

Abstract: Proposed herein is a method and device for receiving a WUR discovery frame in a wireless LAN system. More specifically, a station (STA) receives a WUR discovery element from an access point (AP). The STA receives the WUR discovery frame from a neighbor AP based on the WUR discovery element. The WUR discovery element includes AP list information. The AP list information includes information on a WUR discovery period. The WUR discovery frame is received during the WUR discovery period.

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: Provided is a method and device for transceiving a frame in a wireless LAN system. Particularly, an AP transmits a first frame to a first STA via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a DL transmission and a UL transmission. The relationship between the first STA and the second STA is a hidden node. A PHY header of the first frame includes channel status information of the second band. An NAV of the first STA is set up on the basis of the channel status information.

Abstract: A method for an STA for receiving a WUR frame in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a WUR frame including a first portion of a TSF timer and an MIC value; calculating an MIC verification value on the basis of the first portion of the TSF timer and the TSF timer stored in the STA; and determining whether to discard the received WUR frame depending on whether the MIC value included in the WUR frame matches the calculated MIC verification value, wherein the first portion of the TSF timer included in the WUR frame is the 8-bits following the least significant N-bit in the TSF timer, and the STA may obtain a continuous 48-bit partial TSF timer value through the first portion of the TSF timer and a second portion of the TSF timer stored in the STA, and may calculate the MIC verification value on the basis of the obtained 48-bit partial TSF timer value.

Abstract: The present specification proposes a technical feature related to a wake-up radio (WUR) STA. Specifically, proposed is an operation applied when a WUR STA having a service period (SP) enters a WUR mode. For example, an operation for an SP positioned next to a section in which a wake-up packet (WUP) is transmitted and an operation for an SP positioned after a section in which a WUP is not transmitted may be set to be different from each other. Accordingly, proposed is a technique of efficiently controlling a conventionally negotiated SP in the WUR mode.

Abstract: The present specification proposes a technical feature related to a wake-up radio (WUR) STA. Specifically, proposed is an operation of updating a parameter related to an operation of a WUR mode. For example, the WUR STA may update a parameter related to the WUR mode by receiving an unsolicited frame from an AP while maintaining the WUR mode. The received frame may have a preset action type.

Abstract: A method by which a station (STA) receives a frame in a wireless LAN (WLAN), according to one embodiment of the present disclosure, comprising: receiving a first primary connectivity radio (PCR) frame including a counter value related to a version of a PCR system parameter through a PCR; storing the counter value, which is acquired through the first PCR frame, and entering a wake-up radio (WUR) mode; receiving a first WUR frame through the WUR; and determining whether to perform wake up based on reception of the first WUR frame, wherein the first WUR frame includes a counter field, and the STA can determine whether to perform wake up based on whether a value of the counter field of the first WUR frame corresponds to the stored counter value.

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).
