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, and the first information has a length of 3 bits, wherein the first information indicates whether the PPDU is an extremely high throughput (EHT) PPDU,
wherein the U-SIG field further includes second information related to whether the PPDU is related to a single user (SU) transmission,
wherein based on the PPDU being related to the SU transmission and the bandwidth of the PPDU being greater than 20 MHz, the EHT-SIG field has a single content channel which is duplicated in every 20 MHz subchannel,
wherein the single content channel includes a common field and a user specific field; and
decoding the PPDU based on the U-SIG field and the EHT-SIG field.
