Abstract
According to various embodiments, a multi-link device including a first STA and a second STA may receive a first PPDU by means of the first STA. The PPDU may include information about traffic buffered in the second STA operating in a second link. In response to the first PPDU, the multi-link device may change the second STA from a doze state to an awake state, and transmit information about the state of the second STA by means of the second STA.
Claims18
A method performed by a multi-link device (MLD) including a first station (STA) and a second STA in a wireless local area network system, the method comprising:
- receiving, through the first STA operating in a first link, a first physical layer protocol data unit (PPDU),
- wherein the first PPDU includes information on traffic buffered in the second STA operating in a second link;
- changing the second STA from a doze state to an awake state in response to the first PPDU;
- and
- transmitting, through the second STA, a second PPDU including information on a state of the second STA, after the state of the second STA is changed to the awake state.
A method performed by an AP multi-link device (MLD) including a first access point (AP) and a second AP in a wireless local area network system, the method comprising:
- transmitting, to a first station (STA) through the first AP operating in a first link, a first physical layer protocol data unit (PPDU),
- wherein the first PPDU includes information on traffic buffered in the second STA operating in a second link;
- and
- receiving, through the second AP operating in the second link, a second PPDU including information on a state of the second STA, after the state of the second STA is changed to the awake state.
A multi-link device (MLD) in a wireless local area network system, the MLD comprising:
- a first station (STA) operating in a first link among a multi-link;
- a second STA operating in a second link among the multi-link;
- and
- a processor coupled to the first STA and the second STA, wherein the processor is adapted to,
- receive, through the first STA, a first physical layer protocol data unit (PPDU), wherein the first PPDU includes information on traffic buffered in the second STA;
- change the second STA from a doze state to an awake state in response to the first PPDU;
- and
- transmit, through the second STA, a second PPDU including information on a state of the second STA, after the state of the second STA is changed to the awake state.
