Abstract
An example according to the present disclosure relates to a technique for identifying a wireless LAN (WLAN) packet. For example, when a physical protocol data unit (PPDU) includes a legacy signal field, a field contiguous to the legacy signal field may be used to identify a type of the PPDU. A field contiguous to the legacy signal field may include information indicating that the PPDU is an extreme high throughput (EHT) PPDU. The field contiguous to the legacy signal field may include at least one of information related to a frame format, a transmission opportunity, an STA ID, and/or a bandwidth.

A method in a wireless local area network (WLAN) system, the method comprising:
- receiving a physical protocol data unit (PPDU),
- wherein the PPDU includes a legacy signal field, a control signal field contiguous to the legacy signal field, and a data field,
- wherein the legacy signal field is received through a first symbol, and the control signal field is received through a second symbol,
- wherein the legacy signal field and the control signal field are generated based on a binary phase shift keying (BPSK) constellation,
- wherein the legacy signal field is generated based on a first signal bit,
- wherein the control signal field is generated based on a second signal bit, and
- wherein the second signal bit includes a first control bit for identifying that the PPDU is an extreme high throughput (EHT) PPDU and a second control bit including information of a duration of transmission opportunity (TXOP) related to the PPDU;
- and
- decoding the PPDU based on the control signal field.
A station in a wireless local area network (WLAN) system, the station comprising:
- a memory;
- and
- a processor coupled to the memory,
- wherein the processor is configured to:
- receive a physical protocol data unit (PPDU),
- wherein the PPDU includes a legacy signal field, a control signal field contiguous to the legacy signal field, and a data field,
- wherein the legacy signal field is received through a first symbol, and the control signal field is received through a second symbol,
- wherein the legacy signal field and the control signal field are generated based on a binary phase shift keying (BPSK) constellation,
- wherein the legacy signal field is generated based on a first signal bit,
- wherein the control signal field is generated based on a second signal bit, and
- wherein the second signal bit includes a first control bit for identifying that the PPDU is an extreme high throughput (EHT) PPDU and a second control bit including information of a duration of transmission opportunity (TXOP) related to the PPDU;
- and
- decode the PPDU based on the control signal field.
A station in a wireless local area network (WLAN) system, the station comprising:
- a memory;
- and

- wherein the processor is configured to:
- generate a physical protocol data unit (PPDU),
- wherein the PPDU includes a legacy signal field, a control signal field contiguous to the legacy signal field, and a data field,
- wherein the legacy signal field is to be transmitted through a first symbol, and the control signal field is to be transmitted through a second symbol,
- wherein the legacy signal field and the control signal field are generated based on a binary phase shift keying (BPSK) constellation,
- wherein the legacy signal field is generated based on a first signal bit,
- wherein the control signal field is generated based on a second signal bit, and
