[0029] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0030] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. Unless otherwise indicated, the same numerals in different drawings denote the same or similar elements in the following description relating to the drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0032] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0033] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, for example, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0034] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0035] In this embodiment of the disclosure, the process of wireless LAN sensing may be as follows: the initiating device initiates wireless LAN sensing (e.g., initiates a wireless LAN sensing session), and there may be multiple responding devices responding to it.

[0036] Among them, the wireless LAN sensing initiating device and the wireless LAN sensing responding device may include, but are not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0037] For ease of description, the wireless LAN sensing initiating device will be referred to as the initiating device, and the wireless LAN sensing responding device will be referred to as the responding device.

[0038] For example, a client initiates a wireless LAN sensing operation, and multiple associated or unassociated sensing response devices (e.g., three access points (APs)) can respond. Here, "associated" means that an association connection for communication has been established between the initiating and responding devices, while "unassociated" means that no association connection for communication has been established between the initiating and responding devices.

[0039] An Access Point (AP) is a wireless switch used in a wireless network, and also an access device for the wireless network. An AP may include software applications and / or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network. As an example, an AP can be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0040] Multiple responding devices can communicate with each other. For example, both the initiating and responding devices can be clients, and they can communicate by connecting to the same access point (AP).

[0041] Although the client is described above as the initiating device and the AP as the responding device, this disclosure is not limited thereto. For example, the AP can act as the initiating device and the client as the responding device. Furthermore, there is no limitation on the number of initiating and responding devices.

[0042] This disclosure provides a method, apparatus, device, and storage medium for terminating wireless local area network (WLAN) sensing measurements during WLAN sensing processes by initiating and responding devices.

[0043] The method and apparatus are based on the same disclosed concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0044] like Figure 1 As shown in the embodiments of this disclosure, a method for terminating wireless local area network (WLAN) sensing measurement is provided. Optionally, this method can be applied to a WLAN sensing initiating device. Figure 1 The wireless LAN sensing measurement termination method shown may specifically include the following steps:

[0045] Step 101: Determine the first message frame. The first message frame includes wireless LAN sensing measurement establishment identification information. The wireless LAN sensing measurement establishment identification information is used to indicate the termination of the corresponding established wireless LAN sensing measurement.

[0046] Among them, the established wireless LAN sensing measurements refer to the wireless LAN sensing measurements corresponding to the initiating and responding devices established through the wireless LAN sensing measurement establishment process.

[0047] The WLAN sensing measurement setup identifier is the identifier corresponding to the setup of a WLAN sensing measurement. This identifier may include setup identifiers for one or more measurement events and can be used to indicate the termination of one or more established WLAN sensing measurement events. The first message frame may indicate the WLAN sensing measurement setup identifier using one or more bits.

[0048] Step 102: Send the first message frame.

[0049] In this embodiment of the disclosure, the initiating device may send a first message frame to terminate the established wireless local area network sensing measurement corresponding to the wireless local area network sensing measurement establishment identification information.

[0050] As an example, the initiating device may send a first message frame to the responding device. After sending the first message frame, the initiating device terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the first message frame. Simultaneously, the first message frame may instruct the responding device to terminate the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the first message frame.

[0051] In an optional embodiment, the first message frame in the WLAN sensing measurement termination method further includes the device identifier of at least one participating device in the established WLAN sensing measurement.

[0052] The participating equipment includes at least one of the following:

[0053] The device that is associated with the initiating device;

[0054] Devices that have not been associated with the initiating device.

[0055] In other words, the first message frame may also include at least one of the following: the associated identifier (AID) of the device that participated in the established wireless LAN sensing measurement and was associated with the initiating device, or the unassociated identifier (UID) of the device that was not associated with the initiating device.

[0056] Among them, the device that has not established an association with the initiating device can be a device that has established an association with the responding device. The specific device can be determined based on the actual application scenario requirements and is not restricted here.

[0057] As an example, the first message frame includes WLAN sensing measurement establishment identification information and the device identifier of at least one participating device in the corresponding established WLAN sensing measurement.

[0058] In an optional embodiment, if the first message frame also includes the device identifier of at least one participating device in the established WLAN sensing measurement, then if the first message frame includes the device identifier of one participating device, the receiving address corresponding to the first message frame is the unicast address corresponding to that participating device, such as the Medium Access Control (MAC) address of that participating device. If the first message frame includes the device identifiers of multiple participating devices, then the receiving address corresponding to the first message frame is the multicast or broadcast address corresponding to multiple participating devices. In this case, the participating devices can individually reply with a response message frame to the first message frame or reply with a response message frame using resource information carried in the first message frame for replying to the response message frame.

[0059] The response message frame is used to indicate that the first message frame has been received and to determine the termination of the established wireless local area network sensing measurement corresponding to the wireless local area network sensing measurement establishment identification information in the first message frame.

[0060] Among them, the participating devices in the embodiments of this disclosure may include wireless local area network sensing and response devices.

[0061] In other words, when the first message frame includes a device identifier for a participating device, the initiating device sends the first message frame to the participating device corresponding to that device identifier, so that the participating device corresponding to that device identifier terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information. When the first message frame includes identifiers for multiple participating devices, the initiating device sends the first message frame to each participating device via broadcast or multicast, so that each participating device terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information.

[0062] In an optional embodiment, the first message frame in the WLAN sensing measurement termination method can be a WLAN sensing measurement termination message frame.

[0063] In an alternative embodiment, the first message frame in the WLAN sensing measurement termination method may be determined based on the WLAN sensing measurement establishment request frame.

[0064] The first message frame is a variable of the WLAN sensing measurement establishment request message frame. It can be obtained by changing the format of the WLAN sensing measurement establishment request message frame. Alternatively, the first message frame can be obtained by redefining the frame of the WLAN sensing measurement establishment request message without changing its format.

[0065] The first message frame does not include the parameter information required for wireless LAN sensing measurement, such as the number of bandwidth (BW), long training fields (LFT), and number of spatial streams (NSS) supported by wireless LAN sensing measurement.

[0066] In an optional embodiment, the first message frame may be indicated by a first identifier bit as a wireless local area network sensing measurement termination message frame.

[0067] The first message frame can be a message frame obtained based on a wireless LAN sensing measurement establishment request message frame, or it can be a message frame that is redefined when it is necessary to terminate an established wireless LAN sensing measurement.

[0068] The first identifier can be the dialogtoken subfield, whose value, when preset, indicates that the first message frame is a wireless LAN sensing measurement termination message frame. For example, if the preset value is "5", that is, when the value of the dialogtoken subfield is set to "5", it indicates that the first message frame is a wireless LAN sensing measurement termination message frame.

[0069] In some alternative embodiments, the first message frame is obtained by modifying the indication content of the second identifier bit in the wireless LAN sensing measurement establishment request message frame.

[0070] The second identifier includes at least one of the following:

[0071] A flag bit used to indicate the bandwidth supported by established wireless LAN sensing measurements.

[0072] Flag bits used to indicate the number of long training domains (LTFs) for established wireless LAN sensing measurements;

[0073] A flag bit used to indicate the amount of spatial data (NSS) for established wireless LAN sensing measurements.

[0074] The initiating device can indicate the termination of an established WLAN sensing measurement by changing the bandwidth, LTF, NSS, or other content supported by the established WLAN sensing measurement as indicated by the second identifier bit in the WLAN sensing measurement establishment request message frame.

[0075] As an example, if the second flag in the WLAN sensing measurement establishment request message frame indicates that the bandwidth supported by the established WLAN sensing measurement is 20MHz, the initiating device can change it to 40MHz or other different bandwidths to indicate the termination of the established WLAN sensing measurement.

[0076] As an example, if the second flag in the WLAN Sensing Measurement Establishment Request Message frame indicates that the number of LTFs of the established WLAN Sensing Measurement is 2, the initiating device can change it to 4 or other different numbers to indicate the termination of the established WLAN Sensing Measurement.

[0077] As an example, if the second flag in the WLAN Aware Measurement Establishment Request Message frame indicates that the NSS of the established WLAN Aware Measurement is 2, the initiating device can change it to 4 or other different numbers to indicate the termination of the established WLAN Aware Measurement.

[0078] For a device (such as a responding device) that receives the first message frame, it may determine that the first message frame is used to terminate the established wireless LAN sensing measurement based on the first identifier bit used to indicate that the first message frame is a wireless LAN sensing measurement termination message frame, or based on the change in the content indicated by the second identifier bit in the first message frame, and terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame.

[0079] In this embodiment of the disclosure, the first message frame may also include the device identifier of at least one participating device in the established wireless local area network sensing measurement.

[0080] As an example, in this embodiment of the disclosure, the first message frame includes wireless LAN sensing measurement establishment identification information, device identifiers of at least one participating device in the established wireless LAN sensing measurement, and a first identifier bit for indicating that the first message frame is a wireless LAN sensing measurement termination message.

[0081] In an optional embodiment, the wireless LAN sensing measurement termination method may further include:

[0082] Receive a second message frame, which includes wireless LAN sensing measurement establishment identification information;

[0083] Terminating the established wireless LAN sensing measurement corresponding to the identification information.

[0084] The wireless LAN sensing measurement establishment identifier information in the second message frame can also be used to indicate the termination of the established wireless LAN sensing measurement. Thus, the initiating device can terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame after receiving the second message frame.

[0085] The device that sends the second message frame can be a participating device in the established wireless LAN sensing measurement, such as a wireless LAN sensing response device.

[0086] As an example, after the initiating device receives the second message frame sent by the responding device, it can terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identification information in the second message frame.

[0087] In an optional embodiment, the wireless LAN sensing measurement termination method may further include:

[0088] If no measurement result feedback information corresponding to the established wireless LAN sensing measurement is received within a first time period after neither the first message frame nor the second message frame has been sent, the established wireless LAN sensing measurement shall be terminated.

[0089] In an optional embodiment, the first duration can be the longest response duration corresponding to the measurement result feedback information determined during the establishment process of the established wireless LAN sensing measurement, that is, the longest duration during which the initiating device is allowed to wait to receive the measurement result feedback information corresponding to the established wireless LAN sensing measurement.

[0090] The first duration can be determined by any message frame during the wireless LAN sensing measurement establishment process. For example, the first duration can be determined by the wireless LAN sensing measurement establishment request message frame during the wireless LAN sensing measurement establishment process. The specific duration can be determined based on the actual application scenario requirements, and there are no restrictions here.

[0091] As an example, if the initiating device does not receive the measurement result feedback information corresponding to the established wireless LAN sensing measurement from the responding device within a first time period after neither sending the first message frame nor receiving the second message frame sent by the responding device, the initiating device may terminate the established wireless LAN sensing measurement.

[0092] In an optional embodiment, after the first message frame, the initiating device no longer sends the Null Data Packet (NDP) frame corresponding to the established WLAN sensing measurement establishment identifier information in the first message frame, that is, it no longer sends any information or message frame related to the established WLAN sensing measurement corresponding to the established WLAN sensing measurement establishment identifier information in the first message frame.

[0093] As an example, after the initiating device sends the first message frame to the responding device, it no longer sends any NDP frames to the responding device regarding the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the first message frame.

[0094] Similarly, after sending the first message frame, the initiating device no longer receives the subsequent measurement result feedback information corresponding to the established wireless LAN sensing measurement establishment identifier information in the first message frame.

[0095] As an example, after the initiating device sends the first message frame to the corresponding device, it no longer receives any feedback information from the responding device regarding the measurement results of the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame.

[0096] In an optional embodiment, after receiving the second message frame and terminating the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the second message frame, the initiating device also stops sending subsequent NDP frames corresponding to the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the second message frame.

[0097] As an example, after the initiating device receives the second message frame sent by the responding device and terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the second message frame, it will no longer send any NDP frames to the responding device regarding the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the second message frame.

[0098] Similarly, after the initiating device receives the second message frame sent by the responding device and terminates the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame, it will no longer receive the subsequent measurement result feedback information corresponding to the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame.

[0099] As an example, after the initiating device receives the second message frame sent by the responding device and terminates the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame, it will no longer receive any measurement result feedback information sent by the responding device regarding the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame.

[0100] In one alternative embodiment, the established WLAN sensing measurement can be an established WLAN sensing measurement under any triggering mode.

[0101] Optionally, the established wireless LAN sensing measurements can be either triggered-based (TB) or non-triggered-based (Non-TB) wireless LAN sensing measurements.

[0102] That is, the wireless LAN sensing measurement establishment identification information in the first message frame can be used to indicate the termination of wireless LAN sensing measurement established based on TB method or wireless LAN sensing measurement established based on Non-TB method.

[0103] like Figure 2 As shown, this disclosure provides a method for terminating wireless local area network (WLAN) sensing measurement. Optionally, this method can be applied to a WLAN sensing response device. Figure 2 The wireless LAN sensing measurement termination method shown may specifically include the following steps:

[0104] Step 201: Determine the second message frame. The second message frame includes wireless LAN sensing measurement establishment identification information. The wireless LAN sensing measurement establishment identification information is used to indicate the termination of the corresponding established wireless LAN sensing measurement.

[0105] Among them, the established wireless LAN sensing measurements refer to the wireless LAN sensing measurements corresponding to the initiating and responding devices established through the wireless LAN sensing measurement establishment process.

[0106] Among them, the wireless LAN sensing measurement establishment identifier information is the identifier corresponding to the wireless LAN sensing measurement establishment (settingup). The wireless LAN sensing measurement establishment identifier information may include the establishment identifier of one or more measurement events, and can be used to indicate the termination of one or more established wireless LAN sensing measurement events.

[0107] The second message frame can use one or more bits to indicate the identification information established by the wireless local area network sensing measurement.

[0108] Step 202: Send the second message frame.

[0109] In this embodiment of the disclosure, the responding device may send a second message frame to terminate the established wireless local area network sensing measurement corresponding to the wireless local area network sensing measurement establishment identification information.

[0110] As an example, the responding device may send a second message frame to the initiating device. Upon sending the second message frame, the responding device terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the second message frame. Simultaneously, the second message frame may instruct the initiating device to terminate the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the second message frame.

[0111] In an optional embodiment, the second message frame in the WLAN sensing measurement termination method further includes the device identifier of at least one participating device in the established WLAN sensing measurement.

[0112] The participating equipment includes at least one of the following:

[0113] The device that is associated with the initiating device;

[0114] Devices that have not been associated with the initiating device.

[0115] In other words, the second message frame may also include at least one of the following: the device identifier (AID) of the device that has been associated with the initiating device or the device identifier (UID) of the device that has not been associated with the initiating device, which is involved in the established wireless LAN sensing measurement.

[0116] Among them, the device that has not established an association with the initiating device can be a device that has established an association with the responding device. The specific device can be determined based on the actual application scenario requirements and is not restricted here.

[0117] As an example, the first message frame includes WLAN sensing measurement establishment identification information and the device identifier of at least one participating device in the corresponding established WLAN sensing measurement.

[0118] In an optional embodiment, if the second message frame also includes the device identifier of at least one participating device in the established WLAN sensing measurement, then if the second message frame includes the device identifier of one participating device, the receiving address corresponding to the second message frame is the unicast address of that participating device, such as the MAC address of that participating device. If the second message frame includes the device identifiers of multiple participating devices, then the receiving address corresponding to the second message frame is the multicast or broadcast address corresponding to the multiple participating devices. In this case, the participating devices can individually reply with a response message frame to the second message frame or reply with a response message frame using resource information carried in the second message frame for replying to the response message frame.

[0119] The response message frame is used to indicate that the second message frame has been received and to determine the termination of the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identification information in the second message frame.

[0120] In other words, when the second message frame includes a device identifier for a participating device, the initiating device sends the second message frame to the participating device corresponding to that device identifier, causing the participating device to terminate the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information. When the second message frame includes identifiers for multiple participating devices, the responding device sends the second message frame to each participating device via broadcast or multicast, causing each participating device to terminate the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information.

[0121] In an optional embodiment, the second message frame in the WLAN sensing measurement termination method can be a WLAN sensing measurement termination message frame.

[0122] In an optional embodiment, the second message frame in the WLAN sensing measurement termination method may be determined based on the WLAN sensing measurement establishment request frame.

[0123] The second message frame is a variable of the WLAN sensing measurement establishment request message frame. It can be obtained by changing the format of the WLAN sensing measurement establishment request message frame. Alternatively, the second message frame can be obtained by redefining the frame of the WLAN sensing measurement establishment request message without changing its format.

[0124] The second message frame does not include the parameter information required for wireless LAN sensing measurement, such as the number of BWs and LFTs supported by wireless LAN sensing measurement, as well as related parameters such as (number of NSS).

[0125] In an optional embodiment, the second message frame may be indicated by a first identifier bit as a wireless LAN sensing measurement termination message frame.

[0126] The second message frame can be a message frame obtained based on a wireless LAN sensing measurement establishment request message frame, or it can be a message frame that is redefined when it is necessary to terminate an established wireless LAN sensing measurement.

[0127] The first identifier can be the dialogtoken subfield, and when its value is a preset value, it indicates that the second message frame is a wireless LAN sensing measurement termination message frame. For example, if the preset value is "5", that is, when the value of the dialogtoken subfield is set to "5", it indicates that the second message frame is a wireless LAN sensing measurement termination message frame.

[0128] In some alternative embodiments, the second message frame is obtained by modifying the indication content of the second identifier bit in the WLAN sensing measurement establishment request message frame.

[0129] The second identifier includes at least one of the following:

[0130] A flag bit used to indicate the bandwidth supported by established wireless LAN sensing measurements.

[0131] A flag bit used to indicate the number of LTFs for established wireless LAN sensing measurements;

[0132] The identifier bit used to indicate the NSS of an established wireless LAN sensing measurement.

[0133] The responding device can indicate the termination of an established wireless LAN sensing measurement by changing the bandwidth, number of LTFs, or NSS supported by the established wireless LAN sensing measurement as indicated by the second identifier bit in the wireless LAN sensing measurement establishment request message frame.

[0134] As an example, if the second flag in the WLAN sensing measurement establishment request message frame indicates that the bandwidth supported by the established WLAN sensing measurement is 20MHz, the responding device can change it to 40MHz or another different bandwidth to indicate the termination of the established WLAN sensing measurement.

[0135] As an example, if the second flag in the WLAN Sensing Measurement Establishment Request Message Frame indicates that the number of LTFs of the established WLAN Sensing Measurement is 2, the responding device can change it to 4 or other different numbers to indicate the termination of the established WLAN Sensing Measurement.

[0136] As an example, if the second flag in the WLAN Aware Measurement Establishment Request Message frame indicates that the NSS of the established WLAN Aware Measurement is 2, the responding device can change it to 4 or other different numbers to indicate the termination of the established WLAN Aware Measurement.

[0137] For a device (such as an initiating device) that receives the second message frame, it can determine that the second message frame is used to terminate the established wireless LAN sensing measurement based on the first identifier bit used to indicate that the second message frame is a wireless LAN sensing measurement termination message frame, or based on the change in the content indicated by the second identifier bit in the second message frame, and terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame.

[0138] In this embodiment of the disclosure, the second message frame may also include the device identifier of at least one participating device in the established wireless LAN sensing measurement.

[0139] As an example, in this embodiment of the disclosure, the second message frame includes wireless LAN sensing measurement establishment identification information, device identifiers of at least one participating device in the established wireless LAN sensing measurement, and a first identifier bit for indicating that the second message frame is a wireless LAN sensing measurement termination message.

[0140] In an optional embodiment, the second message frame in the wireless LAN sensing measurement termination method may be encapsulated in an Aggregate Medium Access Control Service Data Unit (A-MSDU) frame or an Aggregate Medium Access Protocol Data Unit (A-MPDU) frame.

[0141] As an example, the responding device can send a second message frame by sending an A-MSDU frame.

[0142] As an example, the responding device can send a second message frame by sending an A-MPDU frame.

[0143] In this embodiment of the disclosure, the second message frame encapsulated in the A-MSDU frame or A-MPDU frame sent by the responding device may include, in addition to the wireless LAN sensing measurement establishment identification information, the device identifier of at least one participating device in the established wireless LAN sensing measurement, and / or a first identifier bit for indicating that the second message frame is a wireless LAN sensing measurement termination message frame.

[0144] As an example, the responding device sends a second message frame by sending an A-MSDU frame. In addition to the identification information of the established wireless LAN sensing measurement, the second message frame also includes the device identifier of at least one participating device in the established wireless LAN sensing measurement.

[0145] As an example, the responding device transmits a second message frame by sending an A-MPDU frame. In addition to the identification information of the established WLAN sensing measurement, the second message frame also includes an identifier bit indicating that the second message frame is a WLAN sensing measurement termination message frame.

[0146] The A-MSDU or A-MPDU frames sent by the responding device also include feedback information on the measurement results corresponding to the established wireless LAN sensing measurements, such as measurement reports corresponding to the established wireless LAN sensing measurements.

[0147] In an optional embodiment, the wireless LAN sensing measurement termination method may further include:

[0148] Receive the first message frame, which includes wireless LAN sensing measurement establishment identification information;

[0149] Terminating the established wireless LAN sensing measurement corresponding to the identification information.

[0150] The wireless LAN sensing measurement establishment identifier information in the first message frame can also be used to indicate the termination of the established wireless LAN sensing measurement. Thus, the responding device can terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame after receiving the first message frame.

[0151] The device that sends the first message frame can be a participating device in the established wireless LAN sensing measurement, such as a wireless LAN sensing initiating device.

[0152] As an example, after receiving the first message frame sent by the initiating device, the responding device may terminate the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identification information in the first message frame.

[0153] In an optional embodiment, the wireless LAN sensing measurement termination method may further include:

[0154] If no NDP frame corresponding to the established WLAN sensing measurement is received within a second time period after neither sending a second message frame nor receiving a first message frame, the established WLAN sensing measurement shall be terminated.

[0155] In an optional embodiment, the second duration can be the longest response duration corresponding to the NDP frame determined during the establishment process of the established wireless LAN sensing measurement, that is, the longest duration during which the responding device can wait to receive the NDP frame corresponding to the established wireless LAN sensing measurement.

[0156] The second duration can be determined by any message frame during the wireless LAN sensing measurement establishment process. For example, the second duration can be determined by the wireless LAN sensing measurement establishment request message frame during the wireless LAN sensing measurement establishment process. The specific duration can be determined based on the actual application scenario requirements, and there are no restrictions here.

[0157] As an example, if the responding device does not receive the NDP frame corresponding to the established WLAN sensing measurement from the initiating device after a second time period if it has neither sent a second message frame nor received a first message frame from the initiating device, the responding device may terminate the established WLAN sensing measurement.

[0158] In one optional embodiment, after the responding device sends the second message frame, it no longer sends the subsequent measurement result feedback information corresponding to the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame, that is, it no longer sends any measurement result feedback information related to the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame.

[0159] As an example, after the responding device sends the second message frame to the initiating device, it no longer sends any feedback information about the measurement results of the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the second message frame.

[0160] Similarly, after the responding device sends the second message frame, it will no longer receive the subsequent NDP frames corresponding to the established wireless LAN sensing measurement establishment identifier information in the second message frame.

[0161] As an example, after the responding device sends the second message frame to the initiating device, it no longer receives any NDP frames from the initiating device regarding the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identification information in the second message frame.

[0162] In an optional embodiment, after receiving the first message frame and terminating the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame, the responding device will also stop sending subsequent measurement result feedback information corresponding to the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame.

[0163] As an example, after the responding device receives the first message frame sent by the initiating device and terminates the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame, it will no longer send any measurement result feedback information to the initiating device regarding the established wireless LAN sensing measurement corresponding to the wireless LAN sensing measurement establishment identifier information in the first message frame.

[0164] Similarly, after receiving the first message frame sent by the initiating device and terminating the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the first message frame, the responding device will no longer receive subsequent NDP frames corresponding to the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the first message frame.

[0165] As an example, after the responding device receives the first message frame sent by the initiating device and terminates the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the first message frame, it will no longer receive any NDP frames sent by the initiating device regarding the established WLAN sensing measurement corresponding to the WLAN sensing measurement establishment identifier information in the first message frame.

[0166] In one alternative embodiment, the established WLAN sensing measurement can be an established WLAN sensing measurement under any triggering mode.

[0167] Optionally, the established wireless LAN sensing measurements can be wireless LAN sensing measurements established based on the TB method or wireless LAN sensing measurements established based on the Non-TB method.

[0168] That is, the wireless LAN sensing measurement establishment identification information in the second message frame can be used to indicate the termination of wireless LAN sensing measurement established based on TB method or wireless LAN sensing measurement established based on Non-TB method.

[0169] Based on the wireless LAN sensing measurement termination method provided in this disclosure, both the wireless LAN sensing initiating device and the wireless LAN responding device can proactively send a message frame including identification information indicating the termination of the established wireless LAN sensing measurement, thereby terminating the established wireless LAN sensing measurement. Furthermore, both the wireless LAN sensing initiating device and the wireless LAN responding device can terminate the established wireless LAN sensing measurement after receiving a message frame including identification information indicating the termination of the established wireless LAN sensing measurement, thus exhibiting high applicability.
