Abstract: In a Wireless Local Area Network system, an STA may receive a trigger frame from an AP. The trigger frame may include a common information field and user information fields. Each of the user information fields may include a first field related to an association identifier (AID) and a second field including information for the STA related to the AID. The second field may include special information for every STA receiving the trigger frame on the basis that the first field has a specific value. The common information field may include a present field related to whether a user information field in which the first field has the specific value is present among the user information fields.

Abstract: In a wireless local area network system, a station (STA) may perform binary convolutional code (BCC) encoding on a data field. The STA may puncture the data field in a first puncturing pattern and may transmit a physical protocol data unit (PPDU) including a control field and the data field. The control field may include control information related to the first puncturing pattern.

Abstract: Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.

Abstract: Proposed are a method and device for transmitting EHT PPDU in a wireless LAN system. Particularly, a transmission STA generates first and second LTF symbols. The transmission STA transmits EHT PPDU comprising the first and second LTF symbols to a reception STA. The first and second LTF symbols are generated on the basis of an LTF sequence for first to fourth spatial streams. In the first LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. In the second LTF symbol, the LTF sequence for the first to fourth spatial streams is mapped to tones in four tone units in a frequency domain. The LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the second LTF symbol is mapped to a tone by means of cyclic shifting, by two tones, the LTF sequence, for the first to fourth spatial streams, mapped to the frequency domain of the first LTF symbol.

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: 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: The present specification relates to a signaling field supporting various transmission methods in a wireless LAN system. The wireless LAN system may support a new transmission method in addition to the basic transmission method, and the configuration of a signaling field may be changed for the new transmission method. The present specification proposes an example of improving a specific field of the Universal Signal (U-SIG) field to support various configurations of the signaling field. For example, based on the validate bit value of the U-SIG field, contents of various SIG fields may be changed, additional SIG fields may be inserted, or various transmission modes may be indicated.

Abstract: Presented are a method by which a multi-RU receives a LDPC-tone-mapped PPDU in a wireless LAN system, and an apparatus. Particularly, a reception STA receives, from a transmission STA, a PPDU including a data field and decodes the data field. The data field is received through the multi-RU. LDPC tone mapping for data tone included in the data field is performed on the basis of a first parameter with respect to the multi-RU. The first parameter is 18 when the multi-RU is an RU in which the 242 tone RU and the 484 tone RU are aggregated.
