1. A method performed by a receiving station (STA) in a wireless local area network (WLAN) system, the method comprising:
receiving a Physical Layer Protocol Data Unit (PPDU),
wherein the PPDU includes a universal signal (U-SIG) field and an extremely high throughput signal (EHT-SIG) field,
wherein the U-SIG field has a length of two symbols, wherein the U-SIG field includes first information related to a Physical layer (PHY) version of the PPDU, wherein the first information has a length of 3 bits, wherein the first information is determined based on whether the PPDU is an extremely high throughput (EHT) PPDU,
wherein the U-SIG field further includes control information indicating that the PPDU is related to a single user (SU) mode,
wherein the EHT-SIG field is configured for a single user (SU),
wherein the EHT-SIG field is duplicated in units of 20 MHZ,
wherein the EHT-SIG field includes a common field and a user specific field; and
decoding the PPDU based on the U-SIG field and the EHT-SIG field.
