Abstract
An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

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.
A method performed by a receiving station (STA) in a Wireless Local Area Network (WLAN) system, the method comprising:

- 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
- decoding the EHT PPDU.
A transmitting station (STA) in a Wireless Local Area Network (WLAN) system, comprising:
- a transceiver configured to transmit and/or receive a wireless signal;
- and
- a processor coupled to the transceiver,
- wherein the processor is configured to:
- generate 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, and
- 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
- transmit the EHT PPDU.
