Abstract
A method performed by a first STA in a wireless local area network (WLAN) according to various embodiments may comprise transmitting or receiving a TWT setup request message and a TWT setup response message. The first STA may perform a TWT operation on the basis of the TWT setup request message and the TWT setup response message. The TWT setup request message and the TWT setup response message may be transmitted or received through a first link included in multiple links. The first STA may set the first link to be in an awake state in order to perform the TWT operation through the first link.
Claims15
A method performed in a wireless local area network (WLAN) system, the method comprising:
- transmitting, by a first station (STA) included in a first multi-link device (MLD) supporting a multi-link operation to a second STA, a Management frame comprising multi-link information related to capability for a plurality of links and target wake time (TWT) information related to the first STA,
- wherein the first STA operates on a first link,
- wherein the TWT information includes link information indicating a link to which the TWT information applies, type information indicating whether the TWT information is related to broadcast or individual TWTs, and time information related to a time at which the first STA requests the second STA to wake;
- and
- based on the Management frame, transmitting, by the first STA, a downlink Physical Protocol Data Unit (PPDU) to the second STA.
A method performed in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a first station (STA) included in a first multi-link device (MLD) supporting a multi-link operation to a second STA, a Management frame comprising multi-link information related to capability for a plurality of links and target wake time (TWT) information related to the second STA,
- wherein the second STA operates on a first link,
- wherein the TWT information includes link information indicating a link to which the TWT information applies, type information indicating whether the TWT information is related to broadcast or individual TWTs, and time information related to a time at which the second STA requests the first STA to wake;
- and
- based on the Management frame, receiving, by the first STA, a downlink Physical Protocol Data Unit (PPDU) from the second STA.
A first station (STA) in a wireless local area network (WLAN) system, comprising:
- at least one processor, wherein the first STA is included in a first multi-link device (MLD) supporting a multi-link operation to a second STA;
- and
- at least one computer memory operatively connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- transmitting a Management frame comprising multi-link information related to capability for a plurality of links and target wake time (TWT) information related to the first STA,
- wherein the first STA operates on a first link,
- wherein the TWT information includes link information indicating a link to which the TWT information applies, type information indicating whether the TWT information is related to broadcast or individual TWTs, and time information related to a time at which the first STA requests the second STA to wake;
- and
- based on the Management frame, transmitting a downlink Physical Protocol Data Unit (PPDU) to the second STA.
