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. ## Claims ### Claim 1 A method performed in a wireless local area network (Wireless Local Area Network) system, the method comprising: transmitting, by a non-AP station (STA), a sensing request frame to an access point (AP), wherein the sensing request frame allows the non-AP STA to invoke a procedure to request the AP to perform a sensing procedure, wherein the sensing request frame is related to at least one sensing responder for which the AP is requested to include in the sensing procedure, wherein the sensing request frame includes address information related to the at least one sensing responder and role information of the at least one sensing responder, wherein the role information has a first value for a sensing receiver role and has a second value for a sensing transmitter role, wherein the first value for the sensing receiver role is set to one (1); receiving, by the non-AP STA, a sensing response frame from the AP in response to the sensing request frame; and receiving, by the non-AP STA, a sensing report frame from the AP, wherein the sensing report frame includes a sensing measurement report received by the AP. ### Claim 2 (depends on 1) The method of claim 1, wherein the first value for the sensing receiver role is contiguous to the second value for the sensing transmitter role. ### Claim 3 (depends on 1) The method of claim 1, wherein the sensing measurement report is received based on a trigger frame transmitted by the AP and at least one trigger-based physical later protocol data unit (PPDU) received by the AP. ### Claim 4 A non-AP station (STA) in a wireless local area network (Wireless Local Area Network) system, comprising: a transceiver adapted to transmit and/or receive a wireless signal; and a processor adapted to control the transceiver, wherein the processor is further adapted to: transmit a sensing request frame to an access point (AP), wherein the sensing request frame allows the non-AP STA to invoke a procedure to request the AP to perform a sensing procedure, wherein the sensing request frame is related to at least one sensing responder for which the AP is requested to include in the sensing procedure, wherein the sensing request frame includes address information related to the at least one sensing responder and role information of the at least one sensing responder, wherein the role information has a first value for a sensing receiver role and has a second value for a sensing transmitter role, wherein the first value for the sensing receiver role is set to one (1); receive a sensing response frame from the AP in response to the sensing request frame; and receive a sensing report frame from the AP, wherein the sensing report frame includes a sensing measurement report received by the AP. ### Claim 5 (depends on 4) The non-AP STA of claim 4, wherein the first value for the sensing receiver role is contiguous to the second value for the sensing transmitter role. ### Claim 6 (depends on 4) The non-AP STA of claim 4, wherein the sensing measurement report is received based on a trigger frame transmitted by the AP and at least one trigger-based physical later protocol data unit (PPDU) received by the AP. ### Claim 7 An access point (AP) in a wireless local area network (Wireless Local Area Network) system, comprising: a transceiver adapted to transmit and/or receive a wireless signal; and a processor adapted to control the transceiver, wherein the processor is further adapted to: receive a sensing request frame from a non-AP station (STA), wherein the sensing request frame allows the non-AP STA to invoke a procedure to request the AP to perform a sensing procedure, wherein the sensing request frame is related to at least one sensing responder for which the AP is requested to include in the sensing procedure, wherein the sensing request frame includes address information related to the at least one sensing responder and role information of the at least one sensing responder, wherein the role information has a first value for a sensing receiver role and has a second value for a sensing transmitter role, wherein the first value for the sensing receiver role is set to one (1); transmit a sensing response frame to the non-AP STA in response to the sensing request frame; and transmit a sensing report frame to the non-AP STA, wherein the sensing report frame includes a sensing measurement report received by the AP. ### Claim 8 (depends on 7) The AP of claim 7, wherein the first value for the sensing receiver role is contiguous to the second value for the sensing transmitter role. ### Claim 9 (depends on 7) The AP of claim 7, wherein the sensing measurement report is received based on a trigger frame transmitted by the AP and at least one trigger-based physical later protocol data unit (PPDU) received by the AP.
