Abstract
An operating method and device in a wireless LAN system are disclosed. A method performed by means of a first AP in the wireless LAN system, according to one embodiment of the present disclosure, comprises the steps of: receiving a MU RTS TXS trigger frame from a second AP; and transmitting a DL PPDU or a first trigger frame to one or more STAs on the basis of the MU-RTS TXS trigger frame, wherein the MU-RTS TXS trigger frame may comprise first information for indicating TXOP allocation related to a multi-AP operation and second information related to the first AP.
Claims15
A method comprising:
- receiving, by a first access point (AP), a multi-user (MU) request-to-send (RTS) transmission opportunity sharing (TXS) trigger frame from a second AP;
- transmitting, by the first AP. a downlink (DL) physical layer protocol data unit (PPDU) or a first trigger frame to at least one STA based on the MU-RTS TXS trigger frame,
- wherein the MU-RTS TXS trigger frame includes first information indicating that the MU-RTS TXS trigger frame is for transmission opportunity (TXOP) allocation related to multi-AP operation and second information related to the first AP.
A first access point (AP) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the at least one transceiver,
- wherein the at least one processor is configured to:
- receive, through the at least one transceiver, a multi-user (MU) request-to-send (RTS) transmission opportunity sharing (TXS) trigger frame from a second AP;
- transmit, through the at least one transceiver, a downlink (DL) physical layer protocol data unit (PPDU) or a first trigger frame to at least one STA based on the MU-RTS TXS trigger frame,
- wherein the MU-RTS TXS trigger frame includes first information indicating that the MU-RTS TXS trigger frame is for transmission opportunity (TXOP) allocation related to multi-AP operation and second information related to the first AP.
(canceled)
A second access point (AP) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the at least one transceiver,
- wherein the at least one processor is configured to:
- transmit, through the at least one transceiver, a multi-user (MU) request-to-send (RTS) transmission opportunity sharing (TXS) trigger frame to a first AP;
- and
- receive, through the at least one transceiver, data transmission and reception result information between at least one STA from the first AP,
- wherein based on the MU-RTS TXS trigger frame, a downlink (DL) physical layer protocol data unit (PPDU) or a first trigger frame is transmitted from the first AP to the at least one STA, and
- wherein the MU-RTS TXS trigger frame includes first information indicating that the MU-RTS TXS trigger frame is for transmission opportunity (TXOP) allocation related to multi-AP operation and second information related to the first AP.
