Abstract: A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, an AP generates a PPDU and transmits the PPDU to a STA. The PPDU includes an extremely high throughput (EHT)-LTF and a data field. The data field includes a pilot tone. The pilot tone is configured based on resource unit (RU) information about a broadband. When the broadband includes four 996-tone RUs based on the RU information, an index for the pilot tone is set to ±{24, 92, 158, 226, 266, 334, 400, 468, 562, 630, 696, 764, 804, 872, 938, 1006, 1048, 1116, 1182, 1250, 1290, 1358, 1424, 1492, 1586, 1654, 1720, 1788, 1828, 1896, 1962, 2030}.

Abstract: A transmission station (STA) of a wireless local area network system according to various embodiments can determine a first code rate and encode first data on the basis of a second code rate which is lower than the first code rate. The transmission STA can again generate second data on the basis of the first code rate and the encoded first data and transmit same.

Abstract: An example according to the present disclosure relates to a technique for identifying a wireless LAN (WLAN) packet. For example, when a physical protocol data unit (PPDU) includes a legacy signal field, a field contiguous to the legacy signal field may be used to identify a type of the PPDU. A field contiguous to the legacy signal field may include information indicating that the PPDU is an extreme high throughput (EHT) PPDU. The field contiguous to the legacy signal field may include at least one of information related to a frame format, a transmission opportunity, an STA ID, and/or a bandwidth.

Abstract: A method for receiving a WUR signal by an STA, according to one embodiment of the present invention, comprises the steps of: detecting a WUR preamble sequence included in a WUR PPDU through a WUR receiver of the STA, while a WLAN receiver of the STA is turned off; obtaining WUR data included in the WUR PPDU, on the basis of a timing synchronized through the WUR preamble sequence; and outputting a wake-up signal to the WLAN receiver through the WUR receiver of the STA if the WUR data is intended for the STA, wherein the WUR preamble sequence used for the synchronization corresponds to a signature sequence carrying specific information, and the specific information may include at least one of an SU/MU indicator indicating whether the WUR PPDU is for a single user (SU) or a multi-user (MU), and information on the bandwidth of the WLAN PPDU to be received after wake-up by the WLAN receiver.

Abstract: Disclosed according to one embodiment of the present invention is a method whereby a first station (STA) transmits signals using dual carrier modulation (DCM) in a wireless LAN system, comprising: modulating HE-SIG B field information and/or data field information on a wireless frame transmitted by the first STA and transmitting same to a second STA, wherein in the case of modulating the HE-SIG B field information and/or the data field information in a BPSK mode, if a random symbol C1 among symbols modulated in the BPSK mode is mapped to a subcarrier K, a symbol formed by rotating the phase of the symbol C1 is mapped to a subcarrier K+N/2 in a repeating manner, wherein N corresponds to the number of subcarriers of a resource unit for transmitting the HE-SIG B field information and the data field information and K is a random integer equal to or less than N/2.

Abstract: Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.
