Abstract: Disclosed is a method for receiving data by a terminal in a wireless communication system. The terminal may receive a physical protocol data unit (physical layer protocol data unit: PPDU) from an access point (APAP) and decode the received PPDU. The PPDU may include a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field including at least one content channel, and the U-SIG field may include a bandwidth field indicating the total bandwidth via which the PPDU is transmitted. The total bandwidth is divided into at least one segment, and at least one of field among same fields includes same information except for a resource unit allocation (RU allocation) field between a first content channel and a second content channel in the same segment among the at least one segment when the at least one content channel is composed of a first content channel and a second content channel.
