[0022] Figure 1 This is an example of how WLAN awareness is demonstrated.

[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, 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.

[0030] As an illustrative embodiment, a typical WLAN sensing measurement process may include: a WLAN sensing session establishment phase, a WLAN sensing measurement establishment phase, and a WLAN sensing measurement termination phase. In the WLAN sensing session establishment phase, the initiator may initiate one or more WLAN sensing sessions. In the WLAN sensing measurement establishment phase, the initiator may establish one or more WLAN sensing measurements. For example, for each WLAN sensing session, the initiator may establish one or more WLAN sensing measurements, wherein the established one or more WLAN sensing measurements can be identified or distinguished by a measurement setup ID. Each established sensing measurement may include one or more sensing measurement events, and sensing measurement operations may be performed in each sensing measurement event. Additionally, reporting operations for sensing measurement results may be selectively performed. In the WLAN sensing measurement termination phase, sensing measurements are stopped and the sensing session is terminated. However, this is merely exemplary, and the various phases of WLAN sensing measurement may be divided differently.

[0031] To increase the efficiency of WLAN sensing measurements, a proxy sensing (SBP) approach can be used. That is, a site (hereinafter referred to as an "SBP STA", "SBP requesting STA", "SBP requesting site", or "STA") can send an SBP request (e.g., an SBP request frame) to an SBP-enabled AP (hereinafter referred to as an "SBP AP", "proxy AP", or "AP"). The AP and one or more STAs (possibly including the STA that sent the SBP request) that are responding complete the WLAN sensing measurements. The implementation of the site (or SBP STA, SBP requesting STA, SBP requesting site, STA) can be similar to the client implementation described above, and the SBP-enabled AP (or SBP AP, proxy AP, AP) can be similar to the AP implementation described above. For simplicity, repeated descriptions are omitted here.

[0032] In the entire SBP process, SBP termination can also occur, which can be initiated by the SBP AP or the SBPrequesting STA. However, the current mechanism for SBP termination is not perfect. For example, when initiated by the SBP AP, there are two possible scenarios: 1. After measurement is completed, the SBP AP initiates SBP termination; 2. After sending the SBP response frame, the SBP AP establishes sensing measurements with a suitable responding STA based on the requirements of the SBP requesting STA in the SBP request frame, but may not find an STA (responding STA) that meets the sensing measurement parameter requirements in the SBP request frame, and thus replies with a termination frame to the SBP requesting STA. However, if only a termination frame is replied to the SBP requesting STA without including the reason for termination, the SBP requesting STA may resend the SBP request frame to the SBP AP. For example, even if a termination frame is sent after measurement is completed, the SBP requesting STA may still resend the SBP request frame, leading to wasted resources. Therefore, enhancement is needed.

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

[0034] Figure 2 This is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be an operation performed by the sending device, for example, Figure 2 The communication method shown can be performed by an SBP requesting station device (i.e., SBP requestingSTA) or an SBP access point device (i.e., SBP AP).

[0035] Reference Figure 2 In step 210, an SBP termination frame is determined, wherein the SBP termination frame may include an identifier bit for indicating the completion status of the sensing measurement. In step 220, the SBP termination frame may be sent. According to embodiments of this disclosure, sending the SBP termination frame may also be referred to as "SBP initiation".

[0036] According to embodiments of this disclosure, the SBP termination frame can have various frame formats. For example, the SBP termination frame can be another type of SBP request frame, where bits in the SBP request frame can be set to special values ​​to identify it as an SBP termination frame (which can be initiated by an SBP requesting STA or SBP AP). In other words, the SBP termination frame can have a similar format to the SBP request frame, but needs to be set to the type of SBP termination frame. For example, the SBP termination frame can also include a type identifier bit for identifying the frame type as an SBP termination frame. That is, the bits set to special values ​​can refer to the type identifier bit in the SBP termination frame. However, this is only exemplary, and this disclosure is not limited thereto; the SBP termination frame can be implemented using different other frame formats. Furthermore, a specific format of SBP termination frame can be defined, that is, the type identifier bit in this embodiment may not be carried.

[0037] According to embodiments of this disclosure, the SBP termination frame can be determined using various methods. For example, if Figure 2 The communication method is executed by the SBP requesting station device, which can determine the SBP termination frame (specifically, determine the aforementioned flag bits in the SBP termination frame) based on whether it has received the sensing measurement results. For example, if Figure 2 The communication method is executed by the SBP access point device. The SBP access point device can determine the SBP termination frame (specifically, determine the above-mentioned flag bits in the SBP termination frame) based on whether the sensing measurement that meets the requirements in the SBP request frame has been established and whether the sensing measurement has been completed.

[0038] When determining the SBP termination frame, the flag bits in the SBP termination frame can be set to different values ​​to indicate the completion status of the sensing measurement. For example, the completion status of the sensing measurement can include: the sensing measurement was completed, or the sensing measurement was not completed (e.g., the sensing measurement could not be completed because no site meeting the requirements of the SBP request site device was found to participate in the sensing measurement).

[0039] According to embodiments of this disclosure, the identifier bit can be set to a first value to indicate that the sensing measurement has been completed. In this case, the device that sends the SBP termination frame can be an SBP requesting site device or an SBP access point device.

[0040] According to embodiments of this disclosure, the identifier bit can be set to a second value to identify that no site has been found to meet the requirements of the SBP request site device to participate in the sensing measurement and to initiate the termination process. In this case, the device that sends the SBP termination frame can only be an SBP access point device.

[0041] As a non-limiting embodiment, the flag bit used to identify the completion status of the sensing measurement may be included in the SBP termination frame in the form of a "reason code". For example, the reason code may be set to indicate that the sensing measurement is completed (corresponding to the "first value" above), or it may be set to indicate that no site was found to participate in the sensing measurement and to initiate the termination process (corresponding to the "second value" above).

[0042] According to embodiments of this disclosure, the SBP termination frame may further include a sensing measurement establishment identifier corresponding to the sensing measurement. Depending on the setting of the identifier bit (e.g., reason code), the sensing measurement establishment identifier may correspond to different meanings.

[0043] For example, when the flag bit is set to a first value, the sensing measurement establishment identifier can correspond to a completed sensing measurement. That is, when the flag bit is set to indicate a completed sensing measurement, if the SBP termination frame also carries a sensing measurement establishment identifier, then that identifier can indicate which sensing measurement was completed. This method can be described as explicitly identifying the completion of a sensing measurement. However, this disclosure is not limited to this; the completion of a sensing measurement can also be identified implicitly. That is, the SBP termination frame does not carry a sensing measurement establishment identifier; for example, the sensing measurement corresponding to the SBP termination frame and its sensing measurement establishment identifier can be obtained through the signaling interaction flow.

[0044] For example, when the flag bit is set to the second value, the sensing measurement establishment identifier can be revoked. According to embodiments of this disclosure, the sensing measurement establishment identifier can be assigned to the STA by the SBP AP in the SBP response frame. For example, the sensing measurement establishment identifier is pre-allocated after the SBP AP receives the SBP request frame (pre-allocation method), or it is assigned during the process of the SBP AP establishing sensing measurement with a suitable responder based on the sensing measurement requirements in the SBP request frame (post-allocation method). If the flag bit (e.g., reason code) is set to indicate that no site meeting the SBP request site device requirements was found to participate in the sensing measurement and a termination procedure is initiated, and the SBP termination frame also carries the sensing measurement establishment identifier, then this sensing measurement establishment identifier can refer to the revoked pre-allocated or post-allocated sensing measurement identifier. However, this disclosure is not limited to this. The SBP termination frame may not carry the sensing measurement establishment identifier in such an explicit manner. For example, the sensing measurement corresponding to the SBP termination frame can be obtained from the signaling interaction flow, and when the identifier bit (e.g., reason code) is set to indicate that no site meeting the requirements of the SBP request site device was found to participate in the sensing measurement and the termination process is initiated, the information that the corresponding sensing measurement establishment identifier has been revoked can be obtained simultaneously or automatically. Such a sensing measurement establishment identifier revoke mechanism can avoid resource waste.

[0045] According to embodiments of this disclosure, when the identifier bit (e.g., reason code) is set to a second value, the SBP termination frame may further include a time information bit and a sensing measurement setup identifier. The time information bit may identify the time when the SBP requesting site device resends the SBP request frame for the sensing measurement, and the sensing measurement setup identifier may be an existing sensing measurement setup identifier. In this case, the SBP termination frame is initiated by the SBP access point device. Since the identifier bit (e.g., reason code) indicates that the reason for initiating the SBP termination frame is that the sensing measurement is incomplete, the SBP termination frame can explicitly specify the time when the SBP requesting site device resends the SBP request frame for the sensing measurement and the existing sensing measurement setup identifier. For example, the SBP requesting STA may resend the SBP request frame within the time specified by the SBP AP (i.e., the time identified by the time information bit), and may carry the existing corresponding sensing measurement setup identifier (measurement setup ID). The existing perception measurement setup identifier can refer to the perception measurement setup identifier allocated when the SBP request frame was sent last time. Carrying the perception measurement setup identifier in the SBP termination frame can avoid repeatedly allocating the perception measurement setup identifier for subsequent SBP request frames, saving signaling and avoiding resource waste.

[0046] According to embodiments of this disclosure, the SBP termination frame can be another type of SBP request frame. Bits in the SBP request frame (e.g., type identifier bits) can be set to special values ​​to identify it as an SBP termination frame (which can be initiated by the SBPrequesting STA or the SBP AP). For example, the SBP termination frame can contain a reason code. For example, the SBP termination frame can also contain a corresponding measurement setup ID (which can be assigned to the STA by the SBP AP in the SBP response frame). If the SBP termination frame is sent by the SBP requesting STA or the SBP AP, the reason code can be set to indicate that the sensing measurement is complete, terminating the SBP sensing measurement corresponding to this measurement setup ID. If the SBP termination frame can only be initiated by the SBP AP, the reason code can be set to indicate that no STA meeting the requirements of the SBP requesting STA is found to participate in the sensing measurement, initiating the termination process, and reclaiming the corresponding measurement setup ID. Or, further, the SBP requesting STA can resend the SBP request frame within the time specified by the SBP AP, which can carry the existing corresponding sensing measurement setup ID.

[0047] According to various embodiments of this disclosure, the content carried by the SBP termination frame can have various different variations.

In other words, the SBP requesting site device can proactively terminate a sense measurement.

For example, the identifier bit (e.g., reason code) used to indicate the completion of sense measurement may be omitted in the SBP termination frame. When the SBP site device receives an SBP termination frame sent by the SBP access point device, it can check whether it has received the sense measurement result (e.g., channel state information (CSI) from each responding STA) corresponding to the sense measurement establishment identifier in the SBP termination frame. If it has been received, it can be determined that the SBP termination frame indicates the completion of sense measurement; if it has not been received, it can be determined that the sense measurement corresponding to the SBP termination frame identifier has not been completed and has been terminated.

That is, when the SBP termination frame includes time information bits, the SBP termination frame may omit identifier bits such as reason codes, and the SBP termination frame may implicitly identify that no site meeting the requirements of the SBP requesting site device has been found to participate in the detection measurement and initiate a termination process.

[0063] Figure 3 This is a flowchart illustrating another communication method according to an example embodiment. Figure 3 The communication method shown can be an operation performed by the receiving device, for example, Figure 3 The communication method shown can be performed by an SBP access point device (i.e., an SBP AP) or an SBP requesting site device (i.e., an SBP requesting STA).

[0064] Reference Figure 3 In step 310, an SBP termination frame may be received, wherein the SBP termination frame may include a flag bit (e.g., reason code) for identifying the completion status of the sensing measurement.

[0065] According to embodiments of this disclosure, the identifier bit can be set to a first value to indicate completion of sensing measurement, wherein the sending device of the SBP termination frame can be an SBP requesting site device or an SBP access point device. For example, in step 310, the SBP requesting site device can receive an SBP termination frame with the identifier bit having the first value from the SBP access point device. Alternatively, in step 310, the SBP access point device can receive an SBP termination frame with the identifier bit having the first value from the SBP requesting site device.

[0066] According to embodiments of this disclosure, the identifier bit can be set to a second value to identify that no site meeting the requirements of the SBP requesting site device was found to participate in the sensing measurement and to initiate a termination process, wherein the sending device of the SBP termination frame is the SBP access point device. For example, in step 310, the SBP requesting site device can receive an SBP termination frame with the identifier bit having the second value from the SBP access point device.

[0067] According to embodiments of this disclosure, the SBP termination frame may further include a sensing measurement establishment identifier corresponding to the sensing measurement.

[0068] According to embodiments of this disclosure, when the flag bit is set to a first value, the perception measurement establishment identifier can correspond to a completed perception measurement; when the flag bit is set to a second value, the perception measurement establishment identifier can be revoked.

[0069] According to embodiments of this disclosure, when the identifier bit is set to a second value, the SBP termination frame may further include a time information bit and a sensing measurement establishment identifier, wherein the time information bit may identify the time when the SBP requests the site device to resend the SBP request frame for sensing measurement, and the sensing measurement establishment identifier may be an existing sensing measurement establishment identifier for sensing measurement.

[0070] According to embodiments of this disclosure, the SBP termination frame may further include a type flag bit for identifying the frame type as an SBP termination frame.

[0071] In step 320, the corresponding operation can be performed based on the SBP termination frame.

[0072] In one embodiment of this disclosure, Figure 3 The communication method shown can be performed by an SBP access point device (i.e., SBPAP). For example, when the SBP access point device receives an SBP termination frame with a first value identifier bit from the SBP request site device in step 310, the SBP access point device can terminate the corresponding sensing measurement in step 320.

[0073] In another embodiment of this disclosure, Figure 3The communication method shown can be performed by an SBP requesting station device (i.e., an SBP requesting STA).

[0074] For example, when the SBP requesting site device receives an SBP termination frame with a first value identifier bit from the SBP access point device in step 310, the SBP requesting site device can end the corresponding sensing measurement in step 320.

[0075] For example, when the SBP requesting site device receives an SBP termination frame with a second value identifier bit from the SBP access point device in step 310, the SBP requesting site device can terminate the corresponding sensing measurement in step 320, or further, delete (or reclaim) the corresponding sensing measurement establishment identifier. Alternatively, the SBP requesting site device can resend the SBP request frame within the time specified by the SBP AP in step 320 based on the time information bit carried in the SBP termination frame. In this case, the existing sensing measurement establishment identifier can be used.

[0076] The communication method according to the embodiments of this disclosure improves the SBP termination process, clearly defines the behavior of SBPrequesting STA, and makes better use of resources.
