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 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: 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.
