Abstract: Proposed are a method and a device 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 an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. In a case where the broadband is a 320 MHz band, the first STF sequence is a sequence including an M sequence and is defined as {M −1 −M 0 M −1 M 0 M −1 −M 0 M −1 M 0 M −1 −M 0 M −1 M 0 M −1 −M 0 M −1 M 0 −M 1 M 0 −M 1 −M 0 M −1 −M 0 M −1 M 0 M −1 −M 0 M −1 M 0 −M 1 M 0 −M −M}*(1+j)/sqrt(2).

Abstract: Proposed are a method and device 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 control field and a data field. If the broadband is a 160/80+80 MHz band that includes a primary 80 MHz channel and a secondary 80 MHz channel, the data field is received via a second multiple RU in which 484-RU and a first multiple RU are aggregated. The first multiple RU is a multiple RU in which first and second 26-RUs, 52-RUs and 106-RUs are aggregated. The second multiple RU is allocated in the primary 80 MHz channel and the secondary 80 MHz channel.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA through a first band, and decodes the PPDU. The PPDU comprises a control field and a data field. When the first band is an 80 MHz band comprising first to fourth 20 MHz subchannels, the first 20 MHz subchannel comprises first multiple RUs in which a first 26RU and a first 52RU are aggregated. The first 26RU is an RU located in the middle of the first 20 MHz subchannel. The first 52RU is an RU having a frequency lower than that of the first 26RU, and which is adjacent to the first 26RU.

Abstract: Proposed are a method and apparatus for receiving PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband and decodes the PPDU. The broadband is a 320 MHz or 160+160 MHz bandwidth that is not preamble punctured. The PPDU includes a first field and a second field. The first field includes L-LTF. The PPDU includes a first signal field and a second signal field. The first field includes L-LTF. The first field is generated on the basis of one of a first, second, third or fourth phase rotation value. The first phase rotation value is a phase rotation value that obtains PAPR of the L-LTE optimized for the broadband on the basis of a first combination of RFs used for transmitting the PPDU. The first combination of RFs is a combination of 160 MHz-capable RFs or 320 MHz-capable RFs.

Abstract: Proposed are a method and device for receiving a feedback frame in a wireless LAN system. Specifically, a first STA transmits an NDPA frame to a second STA. The first STA transmits an NDP frame to the second STA. The first STA receives, from the second STA, a feedback frame transmitted on the basis of the NDP frame. The feedback frame includes information about a beamforming feedback matrix. The information about the beamforming feedback matrix includes a first bit for the index difference between quantized phi of adjacent subcarriers, and a second bit for the index difference between quantized psi of the adjacent subcarriers. The adjacent subcarriers are two adjacent subcarriers starting with the first subcarrier among all of the subcarriers. The first subcarrier is either the left edge subcarrier or the right edge subcarrier. The quantized phi and psi are information about beamforming angles.

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: A method and apparatus for transmitting an EHT PPDU in a wireless LAN system is proposed. Specifically, a transmitting STA generates an EHT PPDU including a STF signal. The transmitting STA transmits the EHT PPDU to a receiving STA. The STF signal is generated on the basis of an EHT STF sequence for a 320 MHz band or a 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a predetermined M sequence is repeated, which is defined as {M 1 M 1 M 1 −M 0 M 1 −M 1 −M 1 M 0 M 1 M 1 M 1 −M 0 −M −1 M −1 M −1 −M}*(1+j)/sqrt(2). The sqrt( ) represents the square root. The predetermined M sequence is defined as M={−1, −1, −1, 1, 1, 1, −1, 1, 1, 1, −1, 1, 1, −1, 1}.
