Abstract
A transmission method and device based on preamble puncturing in a wireless LAN system are disclosed. A method by which a first STA performs communication in a wireless LAN system, according to one embodiment of the present disclosure, comprises the steps of: receiving a first PPDU from a second STA; acquiring information related to at least one first punctured resource unit; and transmitting, in response to the first PPDU, to the second STA, a second PPDU based on at least one second punctured resource unit, wherein the at least one first punctured resource unit can be at least one part of the at least one second punctured resource unit.
Claims10
A method comprising:
- receiving, by a first station (STA), a first physical layer protocol data unit (PPDU) from a second STA;
- obtaining, by the first STA, information related to at least one first punctured subchannel included in the first PPDU;
- and
- in response to the first PPDU, transmitting, by the first STA to the second STA, a second PPDU over at least one subchannel, excluding at least one second punctured subchannel,
- wherein a size of the at least one second punctured subchannel is equal to or bigger than a size of the at least one first punctured subchannel, and
- wherein, based on the second PPDU being an extremely high throughput (EHT) multi-user (MU) PPDU format, a universal-signal (U-SIG) field of the second PPDU includes information related to the at least one second punctured subchannel.
A first station (STA) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the one or more transceivers;
- wherein the at least one processor is configured to:
- receive, through the at least one transceiver, a first physical layer protocol data unit (PPDU) from a second STA;
- obtain information related to at least one first punctured subchannel included in the first PPDU;
- and
- in response to the first PPDU, transmitting, to the second STA through the at least one transceiver, a second PPDU over at least one subchannel, excluding at least one second punctured subchannel,
- wherein a size of the at least one second punctured subchannel is equal to or bigger than a size of the at least one first punctured subchannel, and
- wherein, based on the second PPDU being an extremely high throughput (EHT) multi-user (MU) PPDU format, a universal-signal (U-SIG) field of the second PPDU includes information related to the at least one second punctured subchannel.
A second station (STA) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the one or more transceivers;
- wherein the at least one processor is configured to:
- transmit, to a first STA through the at least one transceiver, a first physical layer protocol data unit (PPDU) including information related to at least one first punctured subchannel;
- and
- receive, from the first STA through the at least one transceiver, a second PPDU over at least one second punctured subchannel, excluding at least one second punctured subchannel, in response to the first PPDU,
- wherein a size of the at least one second punctured subchannel is equal to or bigger than a size of the at least one first punctured subchannel, and
- wherein, based on the second PPDU being an extremely high throughput (EHT) multi-user (MU) PPDU format, a universal-signal (U-SIG) field of the second PPDU includes information related to the at least one second punctured subchannel.
