16 Claims

1. A terminal of 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 a preamble of a physical protocol data unit (PPDU) from an access point (AP),

wherein the preamble comprises a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field,

wherein the U-SIG field includes an uplink (UL)/downlink (DL) field indicating whether the PPDU is an unlink PPDU or a downlink PPDU, and a type field indicating a type of the PPDU, and

wherein the UL/DL field and the type field are used to identify whether the EHT-SIG field includes a resource unit (RU) allocation subfield, and

receive a data of the PPDU, based on the U-SIG field and the EHT-SIG field.
