[0017] The following description, with reference to the accompanying drawings, is provided to aid in a comprehensive understanding of the various embodiments of this disclosure as defined by the appended claims and their equivalents. The various embodiments of this disclosure include a variety of specific details, but these details are to be considered exemplary only. Furthermore, for clarity and brevity, descriptions of well-known techniques, functions, and constructions may be omitted.

[0018] The terms and words used in this disclosure are not limited to their literal meanings, but are used solely by the inventors to ensure a clear and consistent understanding of the disclosure. Therefore, the descriptions of various embodiments of the disclosure provided are for illustrative purposes only and not for limiting purposes.

[0019] It should be understood that, unless the context clearly indicates otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this disclosure means the presence of the described features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0020] It will be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, without departing from the teachings of the example embodiments, the first element discussed below may be referred to as the second element.

[0021] It should be understood that when an element is referred to as “connected” or “coupled” to another element, it can be directly connected or coupled to the other element, or there may be an intermediate element. Furthermore, the use of “connected” or “coupled” herein can include wireless connections or wireless couplings. The terms “and / or” or the expression “at least one of…” as used herein include any and all combinations of one or more of the associated listed items.

[0022] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0023] Figure 1 This is an example of how WLAN awareness is demonstrated.

[0024] The process of WLAN sensing can be as follows: an initiator initiates WLAN sensing (e.g., initiates a WLAN sensing session), and there may be multiple responders responding to it. Specific possible methods include... Figure 1 As shown in (a), (b) and (c) in the figure.

[0025] Reference Figure 1 In (a) of this clause, when a WLAN sensing initiator (e.g., a client) initiates WLAN sensing, multiple associated or unassociated WLAN sensing responders (e.g., three access points (APs)) can respond. Here, "associated" can refer to an association connection established between the initiator and the responder for communication, while "unassociated" can refer to an association connection not established between the initiator and the responder for communication.

[0026] As an example, a client may include, but is 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.

[0027] An access point (AP) can be a wireless switch for a wireless network, or an access device for a 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 may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0028] Figure 1 (b) and Figure 1 Similar to (a) in, but in Figure 1 In (b) of the above, the various responders (APs) can communicate with each other.

[0029] Reference Figure 1 In (c), both the WLAN sensing initiator and the WLAN sensing responder can be clients, and they can communicate by connecting to the same AP.

[0030] Although Figure 1As shown in (a), (b), and (c) above, the client acts as the initiator and the AP as the responder; however, this disclosure is not limited thereto. For example, the AP can act as the initiator and the client as the responder. Furthermore, the number of initiators and responders is not limited to [specific details needed]. Figure 1 As shown in (a), (b) and (c) in the figure.

[0031] A WLAN awareness session initiated by the initiator may include one or more of the following phases: setup phase, measurement phase, reporting phase, and termination phase.

[0032] During the setup phase, a sensory session is established (e.g., Figure 3 (As shown in the "Session Establishment" section), and the operating parameters associated with the sensing session are determined and exchanged between devices. After the sensing session is established, sensing measurement establishment (such as...) is performed. Figure 3 The device initiates a measurement phase (as shown in the "Measurement Setup" section) to perform sensing measurements. During the reporting phase, the sensing measurement results can be reported. In the termination phase, the device stops performing measurements and terminates the sensing session (e.g., [the process is described in the original text]). Figure 3 (The "Perception Session Termination" message is displayed.)

[0033] The measurement phase (or "measurement process") can include multiple sensing measurement events. For example, trigger-based (TB) sensing measurement events can include two methods: trigger frame (TF) sounding and null data packet announcement (NDPA) sounding. Different sensing measurement events may use only one of these two methods or both simultaneously. However, current research lacks a mechanism to define which method and in what order different sensing measurement events should be used, thus affecting the WLAN sensing measurement process.

[0034] In view of the above, a communication method and communication apparatus for sensing measurements in a wireless local area network (WLAN) are provided according to embodiments of the present disclosure.

[0035] Figure 2 This is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be applied to the initiator of WLAN sensing.

[0036] Reference Figure 2 In step 210, at least one sensing measurement process establishment message frame can be determined. According to embodiments of this disclosure, the at least one sensing measurement process establishment message frame may correspond to at least one sensing measurement process, each sensing measurement process may include at least one sensing measurement event, and each sensing measurement process establishment message frame may include information associated with at least one sensing measurement event.

[0037] For example, a sensing measurement process requires a sensing measurement process establishment message frame to establish the sensing measurement. In embodiments of this disclosure, one or more sensing measurement process establishment message frames can be determined simultaneously in step 210, that is, one or more sensing measurement processes are established simultaneously, and in subsequent time, each sensing measurement process is performed sequentially according to the order of establishment. Figure 3 As shown, after a "session establishment", there can be one or more "measurement establishments".

[0038] Each sensing measurement process may include one or more sensing measurement events, such as Figure 3 The "measurement example" shown. In each sensing measurement event, there can be a transmitter and a receiver for the sensing measurement, for example, by performing TF sounding and / or NDPA sounding between the transmitter and receiver. For example, the initiator of WLAN sensing can be a participant in the sensing measurement event, such as the transmitter of the sensing measurement event; or, for example, the initiator of WLAN sensing can not be a participant in the sensing measurement event, that is, the initiator of WLAN sensing is neither a transmitter nor a receiver. Furthermore, it will be understood that although Figure 3 The document shows that "measurement" and "report" exist in a "measurement instance"; however, this disclosure is not limited thereto. For example, each "measurement instance" may only include "measurement" and then "report" may be generated based on further message frames sent by the sender.

[0039] According to embodiments of this disclosure, the at least one sensing measurement process establishment message frame determined in step 210 can be any type of frame, such as a management frame, control frame, or data frame, and this disclosure does not impose specific limitations on it. In embodiments of this disclosure, there can be many ways to determine the sensing measurement process establishment message frame. For example, the sensing measurement process establishment message frame can be generated or configured based on at least one of the following: channel state, network conditions, load conditions, hardware capabilities of the transmitting / receiving device, service type, and relevant protocol specifications; this disclosure does not impose specific limitations on this. In embodiments of this disclosure, the sensing measurement process establishment message frame can also be obtained from an external device, and this disclosure does not impose specific limitations on this.

[0040] The following will describe in detail the specific content of the message frame established during the sensing and measurement process.

[0041] As mentioned above, multiple sensing and measurement processes can exist, and each sensing and measurement process can have a corresponding sensing and measurement process establishment message frame. Therefore, in order to distinguish each sensing and measurement process, an identifier for the sensing and measurement process can be included in the sensing and measurement process establishment message frame. That is, each sensing and measurement process establishment message frame can include: a sensing and measurement process identifier used to identify the sensing and measurement process corresponding to the sensing and measurement process establishment message frame, which can be simply referred to as "measurement process ID" below.

[0042] As described above, each sensing measurement process establishes a message frame that may include information associated with at least one sensing measurement event. According to embodiments of this disclosure, the information associated with at least one sensing measurement event includes at least one of the following:

[0043] A perception measurement event identifier used to identify each of at least one perception measurement event;

[0044] A first identifier used to identify the sender of each sensing measurement event;

[0045] A second identifier used to identify the receiver of each sensing measurement event;

[0046] A third identifier used to identify the sensing measurement method applied to each sensing measurement event.

[0047] Each of the above items will be described in detail below.

[0048] Each sensing measurement process includes at least one sensing measurement event; therefore, the sensing measurement event identifier for each sensing measurement event can correspond to a measurement process. Specifically, each sensing measurement event identifier can be represented using "measurement process ID_measurement event ID".

[0049] The same user (device) can participate in different sensing measurement events. Each sensing measurement event can correspond to a different device. Depending on whether the WLAN sensing initiator participates in the sensing measurement event, the first identifier and / or the second identifier included in the corresponding sensing measurement process establishment message frame can be determined.

[0050] For example, if the WLAN sensing initiator is not both the sender and receiver of each sensing measurement event, the information associated with at least one sensing measurement event may include at least one first identifier and at least one second identifier corresponding to each sensing measurement event. In this case, for a sensing measurement event, the first identifier representing the sender in the sensing measurement event and the second identifier representing the receiver in the sensing measurement event may be in a one-to-one relationship (i.e., one first identifier corresponds to one second identifier (one sender corresponds to one receiver)), a one-to-many relationship (i.e., one first identifier corresponds to multiple second identifiers (one sender corresponds to multiple receivers)), or a many-to-one relationship (i.e., multiple first identifiers correspond to one second identifier (multiple senders correspond to one receiver)).

[0051] For example, when the WLAN sensing initiator is the sender of each sensing measurement event, the information associated with at least one sensing measurement event may include at least one second identifier corresponding to each sensing measurement event. That is, in this case, one or more receivers can be identified in each sensing measurement event.

[0052] According to embodiments of this disclosure, different sensing measurement methods can be used for each sensing measurement event when the third identifier in each sensing measurement event is set to different values. The following description uses the setting of the third identifier in one sensing measurement event as an example, but this description can be applied to any other sensing measurement event.

[0053] In one embodiment of this disclosure, each sensing measurement event may employ a detection method for sensing measurement. For example, when a third identifier is set to a first value, the sensing measurement method is identified as performing sensing measurement using a first detection method; when the third identifier is set to a second value, the sensing measurement method is identified as performing sensing measurement using a second detection method.

[0054] According to embodiments of this disclosure, the first detection method is TF sounding, and the second detection method is NDPA sounding; however, this disclosure is not limited thereto. According to embodiments of this disclosure, in TF sounding, the sender can send a TF frame (which can allocate resources to the receiver), and then the receiver can send an NDP frame to the sender, allowing the sender to perform sensing measurements (e.g., CSI (Channel State Information) measurements); in NDPA sounding, multiple receivers can exist, the sender can send an NDPA frame, followed immediately by an NDP frame, and then each receiver can provide report feedback to the sender, thereby achieving sensing measurements.

[0055] For example, the third identifier may have two bits that, when set to a first value (e.g., but not limited to "00"), can be used for sensing measurement in a first probing mode (e.g., but not limited to "TF sounding") in the sensing measurement event; and when set to a second value (e.g., but not limited to "01"), can be used for sensing measurement in a second probing mode (e.g., but not limited to "NDPA sounding") in the sensing measurement event.

[0056] In another embodiment of this disclosure, each sensing measurement event may employ a combination of at least two detection methods for sensing measurement, and a third identifier may identify the order of each detection method. For example, when the third identifier is set to a third value, the sensing measurement method is identified as follows: first, sensing measurement is performed using a first detection method, and then sensing measurement is performed using a second detection method; when the third identifier is set to a fourth value, the sensing measurement method is identified as follows: first, sensing measurement is performed using a second detection method, and then sensing measurement is performed using a first detection method. For example, as described above, the third identifier can have two bits. When it is set to a third value (e.g., but not limited to "10"), a sensing measurement can be performed first using a first probing method (e.g., but not limited to "TF sounding") and then using a second probing method (e.g., but not limited to "NDPA sounding"). In other words, in this sensing measurement event, a sensing measurement method of first TF sounding and then NDPA sounding can be used. When it is set to a fourth value (e.g., but not limited to "11"), in this sensing measurement event, a sensing measurement can be performed first using a second probing method (e.g., but not limited to "NDPA sounding") and then using a first probing method (e.g., but not limited to "TF sounding"). In other words, in this sensing measurement event, a sensing measurement method of first NDPA sounding and then TF sounding can be used.

[0057] According to embodiments of this disclosure, the initiator of WLAN sensing can generate a sensing measurement process establishment message frame, wherein the sensing measurement process establishment message frame may include:

[0058] A. Measurement process ID, where one sensing measurement process establishment message frame can correspond to one measurement process ID;

[0059] B. Multiple measurement event IDs, where each measurement event ID can correspond to a measurement process ID, specifically in the form of "measurement process ID_measurement event ID";

[0060] C. Transmitter ID (the first identifier as described above) and / or receiver ID (the second identifier as described above), wherein one measurement event ID corresponds to different devices. If the WLAN sensing initiator is neither the transmitter nor the receiver of the sensing (sensing measurement event), it can include the transmitter ID and receiver ID of the participants in this sensing measurement event. The correspondence can be one-to-one, one-to-many, or many-to-one, such as multicast addresses. If the WLAN sensing initiator is a transmitter, it can include receiver IDs, which can be one or more.

[0061] D. The form of sounding (as described above, the third identifier), for example, can be identified using two bits: 0 (00) for TF sounding; 1 (01) for NDPA sounding; 2 (10) for "TF sounding first, then NDPA sounding"; and 3 (11) for "NDPA sounding first, then TF sounding".

[0062] For a sensing measurement process to establish a message frame, the contents of which can be shown in Table 1 below:

[0063] Table 1. Message frames established during the sensing and measurement process

[0064] information describe Measurement process ID1 This message frame corresponds to the sensing measurement process 1. Measurement Process ID1_Measurement Event ID1 Measurement event 1 in the sensing measurement process transmitter ID 11 Sender identifier in measurement event 1 receiver ID 12 Receiver identifier in measurement event 1 sounding Sensing measurement method applied to measurement event 1 Measurement Process ID_Measurement Event ID2 Measurement event 2 in the sensing measurement process receiver ID 21 Receiver identifier in measurement event 2 receiver ID 22 Receiver identifier in measurement event 2 sounding Sensing measurement method applied to measurement event 2 ……

[0065] Although two sensing measurement events are shown in Table 1, this disclosure is not limited thereto. Table 1 may include only one sensing measurement event, or it may include more sensing measurement events. Furthermore, although only one sender identifier and one receiver identifier are shown for sensing measurement event 1, this disclosure is not limited thereto. For example, as mentioned above, the sender identifier and receiver identifier may have a "one-to-one, one-to-many, or many-to-one" relationship.

[0066] Return to reference Figure 2 In step 220, at least one sensing measurement process establishment message frame is sent. For example, such as... Figure 1 As shown, the WLAN sensing initiator can send at least one sensing measurement process establishment message frame to at least one WLAN sensing responder.

[0067] Will understand, Figure 2 The communication methods shown are merely exemplary, and this disclosure is not limited thereto. For example, Figure 2The communication method shown may further include: setting a sensing measurement clock corresponding to each sensing measurement process, wherein the corresponding sensing measurement process is terminated in response to the expiration of the corresponding sensing measurement clock.

[0068] For example, referring to Table 1, a sensing measurement clock corresponding to sensing measurement process 1 can be set. When the sensing measurement clock expires, sensing measurement process 1 is terminated, that is, the various sensing measurement events (sensing measurement event 1, sensing measurement event 2, etc.) included in sensing measurement process 1 end (or complete).

[0069] Furthermore, if the WLAN sensing process includes multiple sensing measurement processes (e.g., multiple sensing measurement process establishment message frames are determined in step 210), a clock for the WLAN sensing process can be set. This clock can contain multiple sensing measurement clocks, and if a corresponding sensing measurement clock expires, the established sensing measurement process should also be terminated. This allows WLAN sensing to be performed within a defined clock cycle while reducing interference to other devices.

[0070] Figure 4 This is a flowchart illustrating another communication method according to an example embodiment. Figure 4 The communication method shown can be applied to WLAN sensing response.

[0071] Reference Figure 4 In step 410, at least one sensing measurement process establishment message frame can be received from the WLAN sensing initiator. The at least one sensing measurement process establishment message frame can correspond to at least one sensing measurement process, each sensing measurement process can include at least one sensing measurement event, and each sensing measurement process establishment message frame can include information associated with at least one sensing measurement event.

[0072] According to embodiments of this disclosure, each sensing measurement process corresponds to a sensing measurement clock, wherein the corresponding sensing measurement process is terminated in response to the expiration of the corresponding sensing measurement clock.

[0073] According to embodiments of this disclosure, each sensing measurement process establishment message frame may further include: a sensing measurement process identifier for identifying the sensing measurement process corresponding to the sensing measurement process establishment message frame.

[0075] A perception measurement event identifier used to identify each of at least one perception measurement event;

[0076] A first identifier used to identify the sender of each sensing measurement event;

[0077] A second identifier used to identify the receiver of each sensing measurement event;

[0078] A third identifier used to identify the sensing measurement method applied to each sensing measurement event.

[0079] According to embodiments of this disclosure, when the wireless LAN sensing initiator is not the sender and receiver of each sensing measurement event, the information associated with at least one sensing measurement event may include at least one first identifier and at least one second identifier corresponding to each sensing measurement event.

[0080] According to embodiments of this disclosure, when the wireless LAN sensing initiator is the sender of each sensing measurement event, the information associated with at least one sensing measurement event may include at least one second identifier corresponding to each sensing measurement event.

[0081] According to embodiments of this disclosure, when the third identifier is set to a first value, the identification sensing measurement method is to perform sensing measurement in a first detection mode; when the third identifier is set to a second value, the identification sensing measurement method is to perform sensing measurement in a second detection mode.

[0082] According to an embodiment of this disclosure, when the third identifier is set to a third value, the identifier perception measurement method is as follows: first, perception measurement is performed in a first detection mode, and then perception measurement is performed in a second detection mode.

[0083] When the third identifier is set to the fourth value, the identifier perception measurement method is as follows: first, perception measurement is performed using the second detection method, and then perception measurement is performed using the first detection method.

[0084] According to embodiments of this disclosure, the first detection method is Triggered Frame (TF) detection, and the second detection method is Null Data Packet Declaration (NDPA) detection.

[0086] In step 420, wireless LAN sensing measurements can be performed based on a message frame established by at least one sensing measurement process. For example, based on the information included in the message frame established by at least one sensing measurement process, one or more sensing measurement events can be executed in one or more sensing measurement processes to achieve WLAN sensing.
