1. A method performed by a transmitting station (STA) in a Wireless Local Area Network (WLAN) system, the method comprising:
generating an Extreme High Throughput Physical Protocol Data Unit (EHT PPDU) including a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a control field, and an EHT signal (EHT-SIG) field,
wherein a length field included in the L-SIG field of the EHT PPDU is set to a value satisfying a condition that a remainder is zero when a value of the length field is divided by three (3),
wherein the RL-SIG field is a repeat of the L-SIG field,
wherein the control field includes 3-bit information related to a physical (PHY) version of a PPDU,
wherein the control field has a length of two symbols,
wherein the EHT-SIG field is contiguous to the control field, and
wherein the control field includes first information related to a basic service set (BSS) color having a length of 6 bits, and second information related to a Transmission Opportunity (TXOP) having a length of 7 bits; and
transmitting the EHT PPDU.
