Abstract
A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, an AP generates a PPDU and transmits the PPDU to a STA through a broadband. The PPDU includes an EHT-LTF and a data field. The data field includes a pilot tone. The coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated. The first pilot sequence is {1 1 1 −1 −1 1 1 1}.
Claims15
A method for transmitting a physical protocol data unit (PPDU) in a wireless local area network (WLAN) system, the method comprising:
- generating, by an access point (AP), a PPDU;
- and
- transmitting, by the AP, the PPDU to a station (STA) through a broadband,
- wherein the PPDU comprises an extremely high throughput (EHT)-LTF and a data field,
- the data field comprises a pilot tone,
- a coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated, and
- the first pilot sequence is {1 1 1 −1 −1 1 1 1}.
An access point (AP) for transmitting a physical protocol data unit (PPDU) in a wireless local area network (WLAN) system, the AP comprising:
- a memory;
- a transceiver;
- and
- a processor operatively connected with the memory and the transceiver,
- wherein the processor generates a PPDU and transmits the PPDU to a station (STA) through a broadband,
- the PPDU comprises an extremely high throughput (EHT)-LTF and a data field,
- the data field comprises a pilot tone,
- a coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated, and
- the first pilot sequence is {1 1 1 −1 −1 1 1 1}.
A method for receiving a physical protocol data unit (PPDU) in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a station (STA), a PPDU from an access point (AP) through a broadband;
- and
- decoding, by the STA, the PPDU,
- wherein the PPDU comprises an extremely high throughput (EHT)-LTF and a data field,
- the data field comprises a pilot tone,
- a coefficient of the pilot tone is set to a second pilot sequence in which a first pilot sequence is repeated, and
- the first pilot sequence is {1 1 1 −1 −1 1 1 1}.
