Abstract: An embodiment of the present invention relates to a technique for configuring a signal field in a wireless communication system. A receiving STA may receive and decode a PPDU. The PPDU may include a control information field, a plurality of signal fields, and a plurality of data fields. The control information field may be duplicated based on a first bandwidth, and the plurality of signal fields may be duplicated based on a second bandwidth. The second bandwidth may be set to be larger than the first bandwidth.

Abstract: In a wireless local area network (LAN) system, a transmission station (STA) may transmit, to a receiving STA, a PHY protocol data unit (PPDU) including a first redundancy version of transmission data. On the basis of whether an acknowledgement (ACK) or negative ACK (NACK) frame is received within a threshold time, the transmission STA may determine a second redundancy version of the transmission data to be retransmitted.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: The present specification proposes a technical feature for increasing a transmission range of a wireless LAN signal. The wireless LAN signal of the present specification, e.g. a transmission physical protocol data unit (PPDU), may be configured on the basis of a duplicate transmission mode. The transmission PPDU of the present specification may comprise a data unit duplicated in frequency. The data unit duplicated in frequency may be configured on the basis of a total bandwidth of the transmission PPDU. The transmission PPDU of the present specification proposes various training fields for the duplicated data unit.

Abstract: According to one embodiment of the present specification, an STA may be connected to a primary AP and a secondary AP simultaneously. The STA may acquire control information related to whether the secondary AP can acquire a transmission/reception signal of the primary AP. Thereafter, the STA may transmit a UL signal to the primary AP. The STA may transmit, on the basis of whether the secondary AP can acquire the transmission/reception signal of the primary AP, a block acknowledgement request (BAR) signal for a UL signal to the secondary AP.

Abstract: A method performed by a first STA in a wireless local area network (WLAN) according to various embodiments may comprise transmitting or receiving a TWT setup request message and a TWT setup response message. The first STA may perform a TWT operation on the basis of the TWT setup request message and the TWT setup response message. The TWT setup request message and the TWT setup response message may be transmitted or received through a first link included in multiple links. The first STA may set the first link to be in an awake state in order to perform the TWT operation through the first link.

Abstract: Proposed are a method and a device for receiving a PPDU having been subjected to LDPC tone mapping in a broadband tone plan in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through broadband and decodes the PPDU. A data tone included in a data field is subjected to LDPC tone mapping on the basis of a first parameter. A tone plan for the 240 MHz band is 3×996 tone RUs, and a tone plan for the 320 MHz band is 4×996 tone RUs. The first parameter is 20.

Abstract: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A reception STA can receive a PPDU. The reception STA can perform a modulo operation with respect to whether or not an L-SIG field is repeated and a value of a length field. The reception STA can determine the received PPDU as an EHT PPDU on the basis of the modulo operation with respect to whether or not the L-SIG field is repeated and the value of the length field.

Abstract: Proposed are a method and a device for transmitting an NGV frame in a wireless LAN system. Specifically, a transmission device generates an NGV frame and transmits same via a first band. The NGV frame includes an L-STF, L-LTF, L-SIG, RL-SIG, NGV-SIG, NGV-STF, NGV-LTF and NGV-Data. The NGV-Data includes at least one midamble. The at least one midamble is generated on the basis of a sequence of the NGV-LTF. The sequence of the NGV-LTF includes two time sequences which, in a frequency domain, are mapped to a tone including two tone units, and in a time domain, are repeated in a single OFDM symbol. The at least one midamble includes one or two OFDM symbols.
