Abstract: A method and a device for transmitting and receiving a PPDU on the basis of an FDD in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP transmits a first downlink (DL) PPDU to the first STA on the basis of the trigger frame. The AP transmits a second DL PPDU to the second STA on the basis of the trigger frame. The AP receives a first uplink (UL) PPDU from the second STA on the basis of the trigger frame. The trigger frame includes bandwidth information of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel. The second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted. The first UL PPDU is received after a preset period after the second DL PPDU is transmitted.

Abstract: One example according to the present specification relates to a method for performing a feedback during a HARQ operation. A reception STA can determine the number of data blocks related to one from among one or more feedback bits, on the basis of the length of a PSDU. The reception STA can transmit the at least one feedback bit to a transmission STA on the basis of the number of data blocks.

Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.

Abstract: Proposed are a method and device for transmitting an EHT PPDU in a wireless LAN system. Specifically, a transmission STA generates an EHT PPDU including an STF signal. The transmission 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 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence, in which a preset M sequence is repeated, defined as {M 1 −M −M 1 −M −M −1 M 0 −M 1 −M −M −1 M 0 M −1 M 0 M 1 −M 0 M −1 M}*(1+j)/sqrt(2). Sqrt( ) denotes square root. The preset M sequence is defined as M={−1, −1, −1, 1, 1, 1, −1, 1, 1, 1, −1, 1, 1, −1, 1}.

Abstract: A method and an apparatus for transmitting an EHT PPDU to a WLAN system are proposed. Specifically, a transmitter generates and transmits an EHT PPDU to a receiver through a 320 MHz band from which an 80 MHz band is punctured. The EHT PPDU includes a legacy preamble and an EHT field. The legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in unit of the 80 MHz band in the 320 MHz band on the basis of an optimal PAPR of the L-STF and L-LTF. The first phase rotation value is [1 1 −1 −1 −j −j j j 1 1 −1 −1 −j −j j j].

Abstract: This specification is related to a long training field (LTF) symbol of a WLAN. The LTF symbol may be generated based on a first LTF generation sequence used for an odd-numbered stream and a second LTF generation sequence used for an even-numbered stream. An even-numbered element of the first LTF generation sequence may be set to zero (0), and an odd-numbered element of the second LTF generation sequence may be set to zero (0). A plurality of LTF symbols for first and third streams may be generated by applying a P mapping matrix to the first LTF generation sequence. A plurality of LTF symbols for a second stream may be generated by applying the P matrix to the second LTF generation sequence.
