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 transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

Abstract: The present specification proposes technical features for improving various fields included in a PPDU. For example, a control signal field included in the PPDU may include a plurality of content channels and may be transmitted through a plurality of frequency segments. The plurality of content channels may include actual allocation information regarding a resource unit allocated to a specific frequency segment. Further, it may include preset information, not actual allocation information, regarding a resource unit allocated to another frequency segment. The preset information may be variously configured, for example, may be embodied as a zero user field.

Abstract: In a wireless local area network (wireless LAN) system, a transmitting STA can transmit, to a receiving STA, a grouping initiation frame for generating a group that is to perform sensing. The grouping initiation frame can include information related to a session identifier (ID) for a sensing session and to the number of transmission times of a sensing signal performed in the sensing session. The transmitting STA can receive a grouping response frame from the receiving STA. The receiving STA can be included in the group on the basis of the reception of the grouping response frame from the receiving STA within a threshold time preset from the transmission time of the grouping initiation frame. The sensing session can include at least one transmission opportunity (TXOP).

Abstract: A method and an apparatus for transmitting an EHT PPDU in a WLAN system are proposed. Specifically, a transmitter generates an EHT PPDU and transmits, on the basis of an RF, the EHT PPDU to a receiver through a 320 MHz band in which an 80 MHz band is punctured. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first scheme and a second scheme. The first scheme is a scheme of obtaining an optimal PAPR in the L-STF and the L-LTF. The second scheme is a scheme of obtaining an optimal PAPR on the basis of the maximum transmission bandwidth supported by the RF. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in units of the 80 MHz band in the 320 MHz band.

Abstract: A method and apparatus for transmitting PPDU in a wireless LAN system are proposed. Specifically, a transmitter generates the PPDU, and transmits the PPDU to a receiver through a 320 MHz band in which some bands are punctured. The PPDU includes a legacy preamble and an EHT field. The legacy preamble includes L-STF and L-LTF. The legacy preamble is generated by applying a first phase rotation value or a second phase rotation value. The first phase rotation value is obtained on the basis of a third phase rotation value and a fourth phase rotation value. The third phase rotation value is a phase rotation value having repeated a phase rotation value defined for an 80 MHz band in an 802.11ax system. The fourth phase rotation value is a phase rotation value defined in units of the 80 MHz band in the 320 MHZ band on the basis of an optimal PAPR of the L-LTF.

Abstract: One embodiment according to the present specification relates to a technique for transmitting information related to a packet extension field in a wireless LAN (WLAN) system. An NGV PPDU can include at least one midamble and a packet extension field set on the basis of the at least one midamble. For example, a duration related to the packet extension field can be set on the basis of the number of the at least one midamble. A preamble of the NGV PPDU can include information related to a packet extension field.

Abstract: This specification is related to a long training field (LTF) symbol of a WLAN. The LTF symbol may be generated based on a first LTF generation sequence used for an odd-numbered stream and a second LTF generation sequence used for an even-numbered stream. An even-numbered element of the first LTF generation sequence may be set to zero (0), and an odd-numbered element of the second LTF generation sequence may be set to zero (0). A plurality of LTF symbols for first and third streams may be generated by applying a P mapping matrix to the first LTF generation sequence. A plurality of LTF symbols for a second stream may be generated by applying the P matrix to the second LTF generation sequence.
