1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), a Physical Protocol Data Unit (PPDU) from a transmitting STA; and
decoding, by the receiving STA, the PPDU,
wherein the PPDU includes a legacy-short training field (L-STF), a legacy-long training field (L-LTF), a legacy-signal (L-SIG), a repeated legacy-signal (RL-SIG), a universal-signal, (U-SIG), an extremely high throughput-signal (EHT-SIG), an EHT-STF, an EHT-LTF and a data field,
wherein a bandwidth of the PPDU is 320 MHz, and a first preamble puncturing pattern in which a 40 MHz or 80 MHz band is punctured in the bandwidth of the PPDU is defined,
wherein a first phase rotation value is applied for the L-STF, the L-LTF, the L-SIG, the RL-SIG, the U-SIG and the EHT-SIG,
wherein the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1],
wherein the bandwidth of the PPDU includes first to fourth 80 MHz bands,
wherein the first preamble puncturing pattern includes first to eighth patterns,
wherein the first pattern is a pattern in which a 40 MHz band within the first 80 MHz band in the bandwidth of the PPDU is punctured,
wherein the second pattern is a pattern in which a 40 MHz band within the second 80 MHz band in the bandwidth of the PPDU is punctured,
wherein the third pattern is a pattern in which a 40 MHz band within the third 80 MHz band in the bandwidth of the PPDU is punctured,
wherein the fourth pattern is a pattern in which a 40 MHz band within the fourth 80 MHz band in the bandwidth of the PPDU is punctured,
wherein the fifth pattern is a pattern in which the first 80 MHz band is punctured in the bandwidth of the PPDU,
wherein the sixth pattern is a pattern in which the second 80 MHz band is punctured in the bandwidth of the PPDU,
wherein the seventh pattern is a pattern in which the third 80 MHz band is punctured in the bandwidth of the PPDU, and
wherein the eighth pattern is a pattern in which the fourth 80 MHz band is punctured in the bandwidth of the PPDU.
