Method for transmitting and receiving data in wireless communication system, and wireless communication terminal

A terminal in a wireless communication system, the terminal comprising:

• a communication module;
• and
• a processor configured to control the communication module,
• wherein the processor is configured to:
• receive an extremely high throughput physical layer protocol data unit (EHT PPDU) comprising one or more EHT-signal (SIG) content channels from an access point (AP),
• wherein each EHT-SIG content channel of the one or more EHT-SIG content channels includes a user specific field and a common field including at least one first resource unit (RU) allocation subfield, and
• wherein a specific field positioned before the at least one first RU allocation subfield is used to identify whether the common field includes at least one second RU allocation subfield after the at least one first RU allocation subfield, and
• decode the common field included in the EHT PPDU,
• wherein the common field includes i) a first coding block in which the at least one first RU allocation subfield is encoded and ii) a second coding block in which the at least one second RU allocation subfield is encoded when the common field further includes the at least one second RU allocation subfield, and
• wherein the specific field corresponding to each EHT-SIG content channel of two or more EHT-SIG content channels is set to a same value when the EHT PPDU includes the two or more EHT-SIG content channels.
