1. A method, the method comprising:
receiving, by a receiving station (STA), an extremely high throughput (EHT) Physical Protocol Data Unit (PPDU) from a transmitting STA; and
decoding, by the receiving STA, the EHT PPDU,
wherein the EHT PPDU includes a legacy preamble, a Universal-Signal (U-SIG) field and an Extremely High Throughput-Signal (EHT-SIG) field,
wherein for the legacy preamble, the U-SIG field and the EHT-SIG field, a phase rotation is defined for a 320 MHz EHT PPDU transmission,
wherein the phase rotation is obtained among 320 MHz phase rotations for subcarrier indexes from −512 to 511,
wherein the 320 MHz phase rotations are obtained based on repeating [1 −1 −1 −1 ] per 80 MHZ frequency subblock,
wherein coefficients with a value of −1 are applied to the 320 MHz phase rotations for the second highest 80 MHz frequency subblock and the highest 80 MHz frequency subblock, and
wherein for the 320 MHZ EHT PPDU transmission, a first preamble puncturing pattern in which a 40 MHz or 80 MHz band is punctured in the bandwidth of the PPDU is defined.
