Abstract
According to various embodiments, a reception STA may receive a physical layer protocol data unit (PPDU) including a first signal field, a second signal field, and a data field. The PPDU may be configured to be transmitted to a single user. The second signal field may consist of one content channel, and the one content channel may be duplicated in a first bandwidth in units of a second bandwidth.

1-20. (canceled)
A method in a receiving station (STA) in a wireless local area network (WLAN), the method comprising:
- receiving a Physical layer Protocol Data Unit (PPDU) including a universal signal (U-SIG) field, an extreme high throughput signal (EHT-SIG) field, and a data field,
- wherein the EHT-SIG field is contiguous to the U-SIG field
- wherein the U-SIG field includes three bit information related to a physical version of the PPDU,
- wherein the U-SIG field is received through two symbols,
- wherein the PPDU is transmitted to a single user,
- wherein the PPDU is received based on an entire bandwidth of the PPDU,
- wherein the EHT-SIG field is configured as one content channel,
- wherein the one content channel is configured by being duplicated in units of 20 MHz within the entire bandwidth of the PPDU;
- and
- decoding the PPDU based on the first signal field and the second signal field.
