摘要： 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.

摘要： A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module; and a processor configured to control the communication module. The processor receives a radio resource control (RRC) signal from a base station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.
