Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wideband 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 wideband. When the wideband is a 320 MHz band, the first STF sequence is a sequence including a M sequence and 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 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 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).

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 20 MHz 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.

Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. In detail, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first and second subblocks. The data field includes first data for the first subblock and second data for the second subblock. The first data is generated on the basis of data in which constellation mapping is performed on encoded data bits. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation thereto.

Abstract: A method for providing ACK and/or NACK information in a WLAN system is proposed. The method proposes configuring a second PPDU in response to receiving a first PPDU. The second PPDU includes a legacy part, a control signal field, and a training field. The training field of the second PPDU may be configured based on whether the data field of the first PPDU is successfully received. The training field may be configured based on a first LTF sequence for indicating a successful reception of the first PPDU. The training field may be configured based on a second LTF sequence for indicating an error of the first PPDU.
