Abstract: The present specification proposes a new procedure of signal transmission or reception between STAs in a case of sensing measurement initiated by an STA rather than an AP. According to an embodiment of the present specification, proposed is a sensing measurement procedure performed by an AP in response to transmission of a sensing initiation frame to the AP by an STA rather than the AP. According to another embodiment of the present specification, according to an embodiment of the present specification, proposed is a procedure in which an STA rather than an AP transmits a sensing initiation frame to the AP, and then the AP requests respondent STAs to transmit NDP frames. According to yet another embodiment of the present specification, proposed is a method for configuring a frame transmitted or received in the above procedures.

Abstract: The specification proposes a method for requesting information on a restricted TWT when an STA has failed to receive the information. According to an embodiment of the present specification, when an STA fails to acquire information on a restricted TWT, the STA may transmit, to an AP, a signal for requesting the information on the restricted TWT after a certain time elapses from a TBTT. The signal may be transmitted independently or may be transmitted together with another signal transmitted by the STA.

Abstract: Proposed are a method and a device for configuring a spatial reuse field in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA through a preconfigured frequency band. The trigger frame includes a common information field and a special user information field. The common information field includes a first to a fourth spatial reuse field. Values of the first to fourth spatial reuse fields are configured to 0 or 15.

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).
