[0016] 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.

[0017] 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.

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.

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.

[0020] 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.

[0021] 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.

[0022] Figure 1 This illustrates an exemplary way of WLAN awareness.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Although Figure 1 As 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, in various embodiments of this disclosure, the AP may act as the initiator and the client as the responder. Furthermore, in various embodiments of this disclosure, the client may also be referred to as a non-AP STA, or simply "STA". Moreover, the number of initiators and responders is not limited. Figure 1 As shown in (a), (b) and (c) in the figure.

[0030] As an illustrative embodiment, the WLAN sensing process may include: WLAN sensing session establishment, WLAN sensing measurement establishment, and WLAN sensing measurement termination. During WLAN sensing session establishment, operational parameters associated with the sensing session can be determined and exchanged between devices. During WLAN sensing measurement establishment, sensing measurements and / or reporting of measurement results can be performed. During sensing measurements, one of the AP and STA can act as a transmitter to send message frames (e.g., NDP (null data packet) frames) for sensing measurements, and the other can act as a receiver to receive message frames (e.g., NDP frames) for sensing measurements, thereby completing a specific sensing measurement event and obtaining measurement results. During WLAN sensing measurement termination, the devices stop performing measurements and terminate the sensing session. It will be understood that the WLAN sensing process described above is merely exemplary, and some stages may be omitted, or some stages may be combined or split.

[0031] Furthermore, in WLAN sensing technologies, trigger-based (TB) sensing measurement and non-trigger-based (Non-TB) sensing measurement have been proposed. In TB sensing measurement, the AP can be the initiator. For example, in the establishment of WLAN sensing measurement, the AP can initiate the sensing measurement establishment, and the STA can respond to the AP's initiation. In Non-TB sensing measurement, the STA can be the initiator. For example, the STA sends a Null Data Packet Announcement (NDPA) frame to the AP to perform sensing measurement, which can be uplink or downlink sensing measurement, or both.

[0032] In conventional TB-based sensing measurements and Non-TB-based sensing measurements, the AP or STA initiates the sensing measurement as the initiator, and can be the sender or receiver of message frames (e.g., NDP frames) used for sensing measurements. Furthermore, in AP-initiated responder-to-responder sensing measurements, the AP may be neither the receiver nor the sender of NDP frames, or the AP may act as the receiver of NDP frames (similar to uplink sensing measurements in Non-TB-based sensing measurements), or the AP may need to receive sensing measurement reports. However, current WLAN sensing measurement mechanisms lack corresponding signaling to explicitly define the sensing measurement establishment process.

[0033] In view of this, a communication method and communication apparatus for establishing sensing measurements are provided according to the concept of embodiments of the present disclosure.

[0034] 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 access point (AP) devices. In other words, Figure 2 The communication method shown can be applied to the initiator (AP) of WLAN sensing.

[0035] Reference Figure 2 In step 210, a wireless frame is determined, wherein the wireless frame may include sensing measurement parameter information set by the access point device.

[0036] In the embodiments of this disclosure, there can be many ways to determine the wireless frame. For example, the wireless 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 devices, service type, and relevant protocol specifications; this disclosure does not impose specific limitations on this. In the embodiments of this disclosure, the wireless frame can also be obtained from an external device, and this disclosure does not impose specific limitations on this. For example, as a non-limiting embodiment, the wireless frame can be determined based on the sensing operation parameter capability information supported by the initiator and receiver exchanged during the sensing measurement session establishment process performed before the sensing measurement is established; for example, determining various sensing measurement parameter information in the wireless frame.

[0037] According to embodiments of this disclosure, the wireless frame can be various types of frames, such as, but not limited to, a sensing measurement establishment request frame. In other words, Figure 2 The communication method shown can be a communication method performed during the establishment of sensing measurements.

[0038] In step 220, a radio frame may be sent. For example, the initiating AP may send the radio frame determined in step 210 to the responding STA, enabling the responding STA to obtain the sensing measurement parameter information set by the AP.

[0039] According to various embodiments of this disclosure, the wireless frame may include various sensing measurement parameter information set by the AP.

[0040] In one embodiment of this disclosure, a communication method for establishing sensing measurements is provided. The sensing measurement establishment request frame may include a first identifier bit, which can be used to identify whether an access point device initiates a responder-responder sensing measurement establishment. Initiating a responder-responder sensing measurement establishment may refer to a site device acting as a responder sending a message frame for sensing measurements. For example, the message frame for sensing measurements may be an NDP frame. An NDP frame may include operating parameters required for performing WLAN sensing measurements, such as the number of spatial streams, the operating bandwidth of the NDP frame, the long training field (LTF), and the packet extension field (PE). However, this disclosure is not limited to this; other frames carrying operating parameters required for performing WLAN sensing measurements are also feasible.

[0041] As a non-limiting embodiment, the AP may use at least one bit to set a first flag bit. For example, when the first flag bit is set to a specific value (e.g., but not limited to "1"), the first flag bit may identify that the AP initiates a responder-responder sensing measurement establishment. That is, the AP may set the first flag bit to a specific value in a radio frame (e.g., a sensing measurement establishment request frame) to identify that in an AP-initiated sensing measurement establishment, the responder (STA) sends an NDP frame as the sender to perform a specific sensing measurement event.

[0042] According to reference Figure 1 In the described embodiment, in TB sensing measurement, the AP initiates the sensing measurement establishment as the initiator. In this embodiment, the AP may set a first flag bit in the radio frame (e.g., sensing measurement establishment request frame) to identify that the AP further initiates responder-responder sensing measurement establishment in TB sensing measurement.

[0043] In one embodiment of this disclosure, a communication method for establishing sensing measurements is provided. The sensing measurement establishment request frame may include a sensing receiver identifier bit. When the sensing receiver identifier bit is set to a first value (e.g., but not limited to "1"), it indicates that the access point device (AP) is receiving a message frame (e.g., an NDP frame) for sensing measurements. That is, the AP can set the sensing receiver identifier bit in a radio frame (e.g., a sensing measurement establishment request frame) to indicate that the AP can receive an NDP frame sent by one of the responders (STAs) during the initiated sensing measurement establishment.

[0044] In one embodiment of this disclosure, a communication method for establishing sensing measurements is provided, wherein a sensing measurement establishment request frame may include a sensing measurement report identifier bit. The sensing measurement report identifier bit is used to indicate whether the access point (AP) receives a report of sensing measurement results. For example, when the sensing measurement report identifier bit is set to a second value (e.g., but not limited to "1"), it indicates that the access point device receives the sensing measurement report; when the sensing measurement report identifier bit is set to a third value (e.g., but not limited to "0"), it indicates that the access point device does not receive the sensing measurement report. For example, when the AP sets the sensing measurement report identifier bit to indicate that the AP receives the sensing measurement report in a radio frame (e.g., a sensing measurement establishment request frame), it indicates that the AP can receive a responder-responder NDP sensing measurement report, and during the sensing measurement reporting process, the AP can initiate a sensing measurement report request frame or the responder can directly initiate a sensing measurement report, thereby allowing the AP to obtain the sensing measurement results.

[0045] In one embodiment of this disclosure, a communication method for establishing sensing measurements is provided. The sensing measurement establishment request frame may include a second identifier bit, which is used to identify whether a station device (STA) is a sender or a receiver during the sensing measurement process. The STA may be a responder in establishing sensing measurements with an access point (AP). The AP may use the second identifier bit in a radio frame (e.g., a sensing measurement establishment request frame) to identify whether the STA is a sender or a receiver of a message frame (e.g., an NDP frame) for sensing measurements.

[0046] For example, the second identifier bit may have one or more bits to identify whether one or more STAs are the sender or receiver of an NDP frame. In a sensing measurement process (or sensing measurement event), there may be only one sender of an NDP frame, but there may be one or more receivers of NDP frames.

[0047] As an alternative embodiment, the Sensing Measurement Establishment Request frame may further include an identifier for the STA, for example, using an AID or a UID to identify the STA. The AID may represent the identifier of a STA that has established association communication with the AP, and the UID may represent the identifier of a STA that has not established association communication with the AP. Alternatively, the STA identifier AID or UID may be included in a second identifier bit. For example, a portion of the second identifier bit may be used to identify the AID or UID, and another portion of the second identifier bit may be used to identify whether the corresponding STA is the sender or receiver of the NDP frame. However, this disclosure is not limited thereto; the STA identifier AID or UID may be identified separately from the second identifier bit in the radio frame (e.g., the Sensing Measurement Establishment Request frame), but may correspond one-to-one with the second identifier bit.

[0048] In one embodiment of this disclosure, a communication method for establishing sensing measurements is provided, wherein a sensing measurement establishment request frame may include a sensing measurement establishment identifier. The sensing measurement establishment identifier is used to identify a sensing measurement establishment process initiated by an AP. Optionally, the AP may identify whether a STA participates in the sensing measurement as a sender or a receiver in the sensing measurement establishment process corresponding to the sensing measurement establishment identifier. For example, if the site device is the sender, it may identify that in the sensing measurement event corresponding to the sensing measurement establishment identifier, the site device sends a message frame (e.g., an NDP frame) for sensing measurement; for example, if the site device is the receiver, it may identify that in the sensing measurement event corresponding to the sensing measurement establishment identifier, the site device receives a message frame (e.g., an NDP frame) for sensing measurement.

[0049] In the above embodiments, various sensing measurement parameter information of the AP settings included in the wireless frame (e.g., a sensing measurement establishment request frame) is described separately. It will be understood that various combinations of the content in the above embodiments are possible. Furthermore, the content in the above embodiments is merely exemplary, and the wireless frame may also include various other information.

[0050] For example, in a communication method for establishing sensing measurements provided in this disclosure, various sensing measurement parameter information set by the AP can be included in a radio frame (e.g., a sensing measurement establishment request frame) in the format of a sensing measurement parameter element. As a non-limiting embodiment, the format of the sensing measurement parameter element can be as shown in Table 1 below.

[0051] Table 1. Format of Sensing Measurement Parameter Information Elements

[0052]

[0053] In Table 1, Element ID identifies the sensing measurement parameter information element, Length identifies the length of the sensing measurement parameter information element, and Element ID Extension identifies the extension of the sensing measurement parameter information element.

[0054] Furthermore, the STA receiver / transmitter can correspond to the second identifier bit described with reference to the embodiments above, used to identify whether the STA is a transmitter or a receiver during the sensing measurement process. The Sensing Measurement Setup ID can correspond to the Sensing Measurement Setup ID described with reference to the embodiments above. Although only one STA receiver / transmitter and one Sensing Measurement Setup ID are shown in Table 1, this disclosure is not limited thereto, and Table 1 may include more STA receivers / transmitters and more Sensing Measurement Setup IDs.

[0055] In addition, the Sensing Measurement Parameters field in Table 1 can have the format shown in Table 2 below.

[0056] Table 2. Format of Sensing Measurement Parameter Domain

[0057]

[0058] The Sensing Transmitter in Table 2 identifies whether the AP acts as a transmitter to send message frames (e.g., NDP frames) for sensing measurements. For example, when the Sensing transmitter is set to a specific value (e.g., but not limited to "1"), the AP can act as a transmitter to send NDP frames in the initiated sensing measurement setup; when the Sensing transmitter is set to another specific value (e.g., but not limited to "0"), the AP does not act as a transmitter to send NDP frames in the initiated sensing measurement setup.

[0059] The Sensing Receiver in Table 2 can correspond to the Sensing Receiver identifier bit described with reference to the embodiments above, used to identify whether the AP acts as a receiver to receive message frames (e.g., NDP frames) for sensing measurements. For example, when the Sensing Receiver is set to a specific value (e.g., but not limited to "1"), the AP can act as a receiver to receive NDP frames in the initiated sensing measurement setup; when the Sensing Receiver is set to another specific value (e.g., but not limited to "0" or a reserved bit), the AP does not act as a receiver to receive NDP frames in the initiated sensing measurement setup.

[0060] The Measurement Report Type in Table 2 can be used to identify the type of measurement result for a sensing measurement event. For example, but not limited to, the Measurement Report Type can be set to Channel State Information (CSI), meaning the AP can receive CSI as a measurement result. If the AP participates in the sensing measurement event as a receiver of NDP frames, the Measurement Report Type can be set to a reserved bit.

[0061] The Responder to Responder Measurement Setup in Table 2 can correspond to the first flag bit described with reference to the embodiments above, used to indicate whether the AP initiates a Responder to Responder Measurement Setup. For example, when the Responder to Responder Measurement Setup is set to, for example, but not limited to, "1", it can indicate that the AP initiates a Responder to Responder Measurement Setup; when the Responder to Responder Measurement Setup is set to, for example, but not limited to, "0", it can indicate that the AP does not initiate a Responder to Responder Measurement Setup.

[0062] The Measurement Report in Table 2 can correspond to the Measurement Report flag bit described with reference to the embodiments above, used to indicate whether the AP receives the Measurement Report from the responder STA. For example, when the Measurement Report is set to, for example, but not limited to, "1", the AP receives the Measurement Report; when the Measurement Report is set to, for example, but not limited to, "0", the AP does not receive the Measurement Report.

[0063] While Tables 1 and 2 describe the various sensing measurement parameters that a wireless frame (e.g., a sensing measurement establishment request frame) may include, this does not mean that a wireless frame (e.g., a sensing measurement establishment request frame) must include all the information shown in Tables 1 and 2. For example, the AP may omit some of the information based on information such as the hardware capabilities of the AP and STA, or it may include additional information.

[0064] According to embodiments of this disclosure, the AP sends a sensing measurement establishment request frame to the STA during the sensing measurement establishment process, where the STA is the responder. The sensing measurement establishment request frame may carry at least one identifier bit to indicate that the AP initiates a responder-to-responder measurement event establishment process. For example, the AP may set the "Sensing Receiver" bit in its sensing measurement parameter information field (e.g., Table 2) to "1" to indicate that the AP receives an NDP frame sent by one of the responders (STAs) during the measurement event.

[0065] According to embodiments of this disclosure, the AP sets another bit (e.g., the Measurement Report flag bit) to "1" in the sensing measurement parameter information field (e.g., Table 2) to indicate that the AP can receive the NDP sensing measurement report from the responder, wherein the sensing measurement report request frame can be initiated by the AP or the sensing measurement report can be initiated directly by the responder; setting it to "0" indicates that it does not receive the sensing measurement report.

[0066] According to embodiments of this disclosure, the AP may also include other identifier bits in the sensing measurement establishment request frame, such as a second identifier bit (STA receiver / transmitter in Table 1), used to identify whether the STA establishing the sensing measurement process with the AP is the sender or receiver of the NDP frame in the responder-to-responder sensing measurement process. If the STA is the sender, the STA sends the NDP frame in the sensing measurement event corresponding to the measurement establishment identifier; if the STA is the receiver, the STA receives the NDP frame in the sensing measurement event corresponding to the measurement establishment identifier. According to embodiments of this disclosure, in a sensing measurement event, that is, in the sensing measurement corresponding to a sensing establishment identifier, there may be only one responder-to-responder sensing measurement NDP frame sender, but there may be multiple NDP frame receivers.

[0067] Figure 3 This is a flowchart illustrating another communication method according to an example embodiment. Figure 3 The communication method shown can be applied to station equipment (STA).

[0068] Reference Figure 3 In step 310, the STA receives a wireless frame from the access point device (AP), wherein the wireless frame may include sensing measurement parameter information set by the access point device.

[0069] Alternatively, the wireless frame can establish a request frame for sensing measurements.

[0070] Alternatively, the radio frame may include a first identifier bit, wherein the first identifier bit is used to identify that the access point device initiates a responder-responder sensing measurement establishment. Initiating a responder-responder sensing measurement establishment may refer to a site device acting as a responder sending a message frame (e.g., an NDP frame) for sensing measurements. Since the AP may carry parameter information about multiple site devices in the radio frame, the "site device acting as a responder" in the initiated responder-responder sensing measurement establishment can be the site device receiving the radio frame (i.e., the one performing the response). Figure 3 The STA in the communication method shown can also be a site device other than the site device that receives the radio frame.

[0071] Alternatively, the wireless frame may include a sense receiver identification bit, wherein, when the sense receiver identification bit is set to a first value, it identifies the access point device as a receiver receiving message frames (e.g., NDP frames) for sense measurements.

[0072] Alternatively, the wireless frame may include a sensing measurement report identifier bit, wherein if the sensing measurement report identifier bit is set to a second value, it indicates that the access point device receives a sensing measurement report; if the sensing measurement report identifier bit is set to a third value, it indicates that the access point device does not receive a sensing measurement report.

[0073] Alternatively, the wireless frame may include a second identifier bit, which is used to identify whether the site device is a sender or a receiver during the sensing measurement process. Since the AP may carry parameter information about multiple site devices in the wireless frame, the wireless frame may include multiple second identifier bits, in addition to identifying the site device that received the wireless frame (i.e., the one performing the sensing measurement). Figure 3 In addition to identifying whether the STA (Station) in the communication method shown is acting as a sender or receiver, it can also identify whether other station devices are acting as senders or receivers.

[0074] Alternatively, the wireless frame may include a sensing measurement establishment identifier. For example, if the station device is the sender (e.g., a second identifier bit identifies the station device as the sender), it indicates that in the sensing measurement event corresponding to the sensing measurement establishment identifier, the station device sends a message frame for sensing measurement. For example, if the station device is the receiver (e.g., a second identifier bit identifies the station device as the sender), it indicates that in the sensing measurement event corresponding to the sensing measurement establishment identifier, the station device receives a message frame for sensing measurement.

[0075] The wireless frame, sensing measurement parameter information, first identifier bit, sensing receiver identifier bit, sensing measurement report identifier bit, second identifier bit, and sensing measurement establishment identifier have been described in detail above with reference to various embodiments and Tables 1 and 2. Therefore, for the sake of brevity, repeated descriptions are omitted here.

[0076] In step 320, the STA sends a response frame based on the radio frame. Optionally, when the radio frame received by the STA is a sensing measurement establishment request frame, the response frame sent by the STA can be a sensing measurement establishment response frame. For example, the STA can parse the radio frame to obtain the sensing measurement parameter information set by the AP, and can indicate whether it accepts such sensing measurement parameter information in the response frame. When the STA accepts the sensing measurement parameter information in the radio frame, it can directly indicate "accept" in the response frame; when the STA does not accept the sensing measurement parameter information in the radio frame, it can indicate the sensing measurement parameter information that the STA supports in the response frame, for example, in Tables 1 and 2. In this way, the AP and STA can negotiate the sensing measurement parameter information during the sensing measurement establishment process to complete the sensing measurement establishment that meets various requirements.

[0077] The communication method according to embodiments of this disclosure improves the signaling mechanism in the sensing session establishment process (e.g., improves the signaling format for AP-initiator-responder sensing measurement establishment), making it applicable to WLAN sensing measurements.
