    Abstract: Proposed is a method and device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting 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. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. 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}*(1+j)/sqrt(2).

    Abstract: A wireless communication system and, more particularly, to a method for performing efficient signaling for a reserved sub-band in a wireless LAN system, and a method and an apparatus for signal transmission using the same. To this end, an STA provides resource allocation information for transmitting data to a plurality of STAs using an orthogonal frequency divisional multiple access (OFDMA) or multiple user MIMO (MU-MIMO) method; transmits the resource allocation information to the plurality of STAs; and transmits data to the plurality of STAs according to the resource allocation information. The entire frequency band may include a sub-band which is not used for the data transmission, and it is preferable that the resource allocation information includes a resource allocation bitmap having a form common to the plurality of STAs and indication information which informs a sub-band, from among the entire frequency band, which is not used for the data transmission.
