Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband communication and decodes the PPDU. The PPDU is received on the basis of an OFDMA scheme. The PPDU includes a first signal field. The first signal field includes first information on a preamble puncturing pattern for each 80 MHz band in the broadband communication. The first information consists of a 4-bit bitmap for the 80 MHz band.

Abstract: A method and an apparatus for receiving a PPDU in a wireless LAN system are proposed. Specifically, a receiving STA receives the PPDU from a transmitting STA through an 80 MHz band, and decodes the PPDU. The PPDU includes a preamble and a data field. The 80 MHz band includes first and second 484 tones RUs. The data field includes first data for the first 484 tone RU and second data for the second 484 tone RU. The second data is data obtained by duplicating the first data. The first and second 484 tone RUs are resource units including 484 tones.

Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a receiving STA receives a PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −1 1 1 1 −1 −1 −1 −1 1 −1 −1 1 −1].

Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. When a first band is a 40 MHz band, the first phase rotation value is [1, −1, −1, −1]. Each element of the first phase rotation value is applied for each 10 MHz band in the first band.

Abstract: The present specification provides a technical feature for extended range transmission in a wireless LAN signal. A physical protocol data unit (PPDU) of the present specification may include a universal signal (U-SIG) field. The U-SIG field may be received through first to the fourth symbols, the second symbol may include information in which bit information of the first symbol is repeated, and the fourth symbol may include information in which bit information of the third symbol is repeated. The receiving STA of the present specification may determine the transmission mode of the PPDU based on constellation mapping pattern of the first and second symbols.

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.
