摘要： Disclosed in the present invention are a method for transreceiving a physical protocol data unit (PPDU) in a wireless communication system and a device for same. More specifically, a method for transmitting a physical protocol data unit (PPDU) using a wireless communication device in a wireless communication system comprises the steps of: generating a PPDU including a legacy preamble, an HE-preamble, and a data field; and transmitting the generated PPDU, wherein a minimum integer number of pilot patterns are defined, wherein the minimum integer number is larger than the value obtained by dividing the total number of subcarriers constituting the data field or a fast Fourier transform (FFT) size value used when generating the PPDU by the total number of pilots, wherein specific pilot patterns from among the pilot patterns are allocated to each symbol of the data field, and wherein the index of a subcarrier to which the pilot is mapped may be determined by the pilot patterns.

摘要： Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. A portion of the STF signal is used to transmit an uplink, and can be used for uplink MU PPDUs transmitted from a plurality of STAs. The STF that is suggested, for example, is used for a 40 MHz band or an 80 MHz band and can be generated based on a sequence in which a predetermined M sequence is repeated. The predetermined M sequence can be a binary sequence of which the length is 15 bits.

摘要： Provided are a method and a device for transmitting a feedback frame in a wireless LAN system. Particularly, a first wireless station receives, from a second wireless station, a feedback request field including an LTF. The first wireless station configures feedback information on a wireless channel corresponding to a preset frequency band by using the feedback request field. The first wireless station transmits the feedback information to the second wireless station.

摘要： The present document relates to a wireless communication system and, more particularly, to a method for performing retransmission in a wireless LAN system to which transmission opportunity (TXOP) sharing is applied, and a device therefor. To this end, a station transmits an initial transmission frame including primary access category (AC) information and secondary access category (AC) information; and when there is no response to the secondary AC information of the initial transmission frame, reconfigures a back-off timer value for the secondary AC information and retransmits the secondary AC information according to the reconfigured back-off timer value.
