Abstract
A method and an apparatus for receiving a PPDU in a wireless LAN system are proposed. Specifically, a receiving STA receives the PPDU from a transmitting STA through an 80 MHz band, and decodes the PPDU. The PPDU includes a preamble and a data field. The 80 MHz band includes first and second 484 tone RUs. The data field includes first data for the first 484 tone RU and second data for the second 484 tone RU. The second data is data obtained by duplicating the first data. The first and second 484 tone RUs are resource units including 484 tones.

A method in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a first station (STA), a Physical Protocol Data Unit (PPDU) from a second STA through an 80MHz band;
- and
- decoding, by the first STA, the PPDU including a preamble and a data field,
- wherein the 80 MHz band includes a first resource unit (RU) including 484 tones and a second RU including 484 tones,
- wherein the data field includes first data for the first RU and second data for the second RU,
- wherein the binary phase shift keying (BPSK) are applied for the first RU,
- wherein the first RU is duplicated to the second RU along with a phase rotation,
- wherein the first and second data are received through a single spatial stream.
A first station (STA) configured to operate in a wireless local area network (WLAN) system, the first STA comprising:
- a memory storing instructions;
- a transceiver;
- and
- a processor being operatively connected to the memory and the transceiver, and configured to execute the instructions to perform operations comprising:
- receive a Physical Protocol Data Unit (PPDU) from a second STA through an 80MHz band;
- and
- decode the PPDU including a preamble and a data field,
- wherein the 80 MHz band includes a first resource unit (RU) including 484 tones and a second RU including 484 tones,
- wherein the data field includes first data for the first RU and second data for the second RU,
- wherein binary phase shift keying (BPSK) are applied for the first RU,
- wherein the first RU is duplicated to the second RU along with a phase rotation,
- wherein the first and second data are received through a single spatial stream.
A method in a wireless local area network (WLAN) system, the method comprising:
- generating, by a second station (STA), a Physical Protocol Data Unit (PPDU) including a preamble and a data field;
- and
- transmitting, by the second STA, the PPDU through an 80MHz band to a first STA,
- wherein the 80 MHz band includes a first resource unit (RU) including 484 tones and a second RU including 484 tones,
- wherein the data field includes first data for the first RU and second data for the second RU,
- wherein binary phase shift keying (BPSK) are applied for the first RU,
- wherein the first RU is duplicated to the second RU along with a phase rotation,
- wherein the first and second data are transmitted through a single spatial stream.
