[0025] Figure 1 is an exemplary manner illustrating WLAN awareness.

[0026] The process of WLAN awareness can be: an initiator initiates WLAN awareness (for example, initiates a WLAN awareness session), and there may be multiple responders responding to it. The specific possible methods can be as follows: Figure 1 As shown in (a), (b) and (c).

[0027] Reference Figure 1 In (a), when a WLAN Awareness initiator (e.g., a client) initiates WLAN Awareness, multiple associated or unassociated WLAN Awareness responders (e.g., three access points (APs)) may respond. "Associated" here may mean that an associated connection for communication has been established between the initiator and the responder, and "unassociated" may mean that no associated connection for communication has been established between the initiator and the responder.

[0028] As an example, the client may include, but is not limited to, cellular phones, smart phones, 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.

[0029] An AP can be a wireless switch or access device for a wireless network. An AP can include software applications and / or circuitry that enable other types of nodes in a wireless network to communicate with the outside world and within the wireless network through the AP. For example, an AP can be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0030] Figure 1 (b) and Figure 1 Similar to (a) in Figure 1 In (b), each responder (AP) can communicate with each other.

[0031] Reference Figure 1 In (c), both the WLAN awareness initiator and the WLAN awareness responder can be clients, and the two can communicate by connecting to the same AP.

[0032] Although Figure 1 In (a), (b) and (c) of FIG. 1 , the client is shown as the initiator and the AP is shown as the responder, but the present disclosure is not limited thereto. For example, in various embodiments of the present disclosure, the AP may be the initiator and the client may be the responder. In addition, in various embodiments of the present disclosure, the client may also be referred to as a non-AP station (non-AP STA), referred to as a "station (STA)". In addition, the number of initiators and responders is not limited to Figure 1 As shown in (a), (b) and (c).

[0033] As an illustrative embodiment, the process of WLAN sensing initiated by the initiator may include one or more of the following phases: a sensing session setup phase, a sensing measurement setup phase, a sensing measurement phase, a sensing measurement reporting phase, and a termination phase.

[0034] In the sensing session setup phase, a sensing measurement session may be established, and operating parameters associated with the sensing session may be determined and exchanged between devices. In the sensing measurement setup phase, the initiator and the responder may establish one or more sensing measurement processes, and each sensing measurement setup may be identified using a measurement setup ID. A sensing measurement session may correspond to one or more sensing measurement setups. In the sensing measurement phase, sensing measurement events may be performed based on sensing measurement frames. The sensing measurement reporting phase may be referred to as the reporting phase, and in this phase, sensing measurement results, such as channel state information (CSI), may be reported. In the termination phase, the sensing measurement may be stopped and the sensing session may be terminated.

[0035] It will be understood that the above-described WLAN awareness process is merely exemplary, and some stages thereof may be omitted or combined.

[0036] In WLAN sensing technology, a trigger-based (TB-based) sensing method has been proposed. For example, in the TB-based sensing method, a threshold reporting method can be used in the reporting phase. However, in current research, the mechanism of the threshold reporting method is still not perfect.

[0037] In view of this, the concept according to the embodiments of the present disclosure provides a communication method and a communication device for perception measurement reporting.

[0038] Figure 2is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown may be applied to an access point device (may be referred to herein as an "access point" or "AP" for short).

[0039] Reference Figure 2 In step 210, the AP may receive values ​​for feedback of channel attributes from one or more station devices (hereinafter referred to as "stations" or "STAs"). The values ​​received by the AP may be values ​​regarding the channel attributes measured by the one or more station devices. For example, but not limited to, the values ​​for feedback of channel attributes may be CSI (channel state information) values. For example, but not limited to, the AP may receive CSI values ​​measured by the one or more station devices. For example, but not limited to, the values ​​for feedback of channel attributes may be quantized CSI values. For example, the AP may receive quantized CSI values ​​calculated by the one or more station devices.

[0040] In step 220, the AP may compare the received value with a threshold to determine whether to send a trigger frame. Specifically, based on at least one received value being greater than or equal to the threshold, the AP may send a trigger frame to at least one of the one or more station devices to trigger the at least one station device to report a perception measurement result. For example, the AP may compare the received CSI value or quantized CSI value with a threshold and send a trigger frame when the CSI value or quantized CSI value is greater than or equal to the threshold. For example, but not limited to, the perception measurement result may also be a CSI value or a quantized CSI value.

[0041] In one embodiment of the present disclosure, the AP may set a different threshold for each of one or more site devices, that is, compare the value received from a specific site device (e.g., CSI value) with its corresponding threshold to determine whether to send a trigger frame to the specific site device to trigger the specific site device to report (send) the perception measurement result to the AP. In another embodiment of the present disclosure, the AP may set the same threshold for each of one or more site devices, that is, compare the value received from all site devices (e.g., CSI value) with the threshold to determine whether to send a trigger frame to the site device. However, the present disclosure is not limited to this. For example, the AP may set different thresholds for some of the one or more site devices and set the same threshold for another part of the one or more site devices. Setting thresholds in different ways can increase the flexibility and adaptability of the system and the accuracy of perception measurements.

[0042] For example, when the AP sends a trigger frame, the AP can send a trigger frame to the site device from which it receives a CSI value or a quantized CSI value greater than or equal to the threshold based on the comparison result with the threshold, so that the AP can receive the perception measurement result from the site device that receives the trigger frame.

[0043] exist Figure 2 In the communication method shown, after comparing the value fed back by the STA with a threshold in step 210, the AP determines in step 220 whether to trigger the STA to report the perception measurement result. This helps save signaling in subsequent perception measurements. For example, for STAs whose feedback value in step 210 is less than the threshold, the perception measurement result may not be fed back or the STA may not participate in subsequent perception measurements, thereby saving signaling.

[0044] The communication method according to the embodiment of the present disclosure improves the mechanism of the threshold reporting method to make it applicable to WLAN awareness measurement.

[0045] exist Figure 2 In the embodiment shown, although the AP sets a threshold value for comparison, the threshold value may not be carried in the trigger frame sent to the station device. However, the present disclosure is not limited to Figure 2 The embodiment shown.

[0046] For example, in a communication method for perception measurement reporting provided in the present disclosure, the communication method can be applied to an access point device and can include: receiving values ​​for feedback channel attributes from one or more site devices respectively; and sending a trigger frame to at least one site device among the one or more site devices based on at least one received value being greater than or equal to a threshold, so as to trigger at least one site device to report the perception measurement result, wherein the trigger frame can include information about the threshold.

[0047] For example, a trigger frame may include a threshold value, and the threshold value is set for each of one or more station devices, and the threshold value is used to enable the one or more station devices to determine whether to report the perception measurement results. In other words, the AP can include a specific threshold value in the trigger frame, so that the station device receiving the trigger frame knows the threshold value set (assigned) for it. Here, the AP can set different threshold values ​​for each of the one or more station devices, or the same value. This has been described in the above embodiments, so repeated description is omitted to avoid redundancy.

[0048] According to an embodiment of the present disclosure, the threshold may be a channel state information threshold (i.e., a CSI threshold) or a quantized channel state information threshold (i.e., a quantized CSI threshold). For example, the value for feedback of channel properties and the perception measurement result received by the AP from the site device may be a CSI value, and the CSI value may be compared with the CSI threshold. For example, the value for feedback of channel properties and the perception measurement result received by the AP from the site device may be a quantized CSI value, and the quantized CSI value may be compared with the quantized CSI threshold. The CSI value may refer to a CSI value obtained by direct measurement by the site device, and the CSI threshold may be set for the CSI value. The AP may receive the CSI value to intuitively obtain the channel properties of the corresponding site device. The quantized CSI value may refer to a value obtained by quantizing the measured CSI value, and the quantized CSI threshold may be set for the quantized CSI value. For example, if the CSI value measured by a station is A and the unit used for quantization (or "quantization ratio") is U, the quantized CSI value can be A / U. This reduces the number of bytes occupied by the quantized CSI value and the quantized CSI threshold set for it, thereby saving resources required to transmit the CSI value or CSI threshold and reducing power consumption. In the embodiments of the present disclosure, the unit used for quantization (or "quantization ratio") can be pre-negotiated and determined between the AP and the station device.

[0049] In addition, in an optional embodiment, in a communication method for sensing measurement reporting provided by the present disclosure, the communication method can be applied to an access point device, wherein a trigger frame includes a threshold value, which is set for each of one or more station devices, and the threshold value is also used to enable the one or more station devices to determine whether to report the sensing measurement result; and the trigger frame can include a threshold value presence flag, wherein the threshold value presence flag is used to identify that the trigger frame includes the threshold value. For example, a station device receiving the trigger frame can first parse the threshold value presence flag to determine whether the trigger frame includes the threshold value. When the threshold value presence flag is determined to include the threshold value in the trigger frame, the trigger frame can be further parsed to obtain the specific threshold value, which helps to ensure the accuracy of trigger frame transmission and parsing. According to an embodiment of the present disclosure, the presence of a threshold value (e.g., the presence of a CSI threshold value or a quantized CSI threshold value) can be identified by at least one bit in the trigger frame. In other words, the threshold value presence flag can have at least one bit. For example, the threshold value presence flag can have one bit, and when it is set to a first value (e.g., but not limited to "1"), it indicates the presence of the threshold value; and when it is set to a second value (e.g., but not limited to "0"), it indicates the absence of the threshold value. For another example, the threshold presence flag may have more bits to identify the specific number of thresholds included in the trigger frame. However, the present disclosure is not limited thereto, and the threshold presence flag may also be omitted, and only the threshold is included in the trigger frame.

[0050] Although Figure 2 In the illustrated embodiment, the trigger frame may not carry a threshold, but may carry other information to trigger the site device to send the sensing measurement result.

[0051] For example, in a communication method for perception measurement reporting provided in the present disclosure, the communication method can be applied to an access point device and can include: receiving values ​​for feedback of channel attributes from one or more station devices; and sending a trigger frame to at least one of the one or more station devices based on at least one received value being greater than or equal to a threshold, to trigger the at least one station device to report a perception measurement result, wherein the trigger frame can include a perception measurement setup identifier (measurement setup ID), wherein the perception measurement setup identifier is used to identify the perception measurement process for which the perception measurement result needs to be reported. For example, as described in the above embodiments, in the perception measurement setup phase, the measurement setup identifier can be used to identify the perception measurement process. Therefore, in the perception measurement reporting phase, when the AP sends a trigger frame including the perception measurement setup identifier to the STA, the STA can report the perception measurement result of the perception measurement process corresponding to the included perception measurement setup identifier to the AP.

[0052] For example, a communication method for sensing measurement reporting provided in the present disclosure may be applied to an access point device and may include: receiving values ​​for feedback of channel attributes from one or more station devices; and, based on at least one of the received values ​​being greater than or equal to a threshold, sending a trigger frame to at least one of the one or more station devices to trigger the at least one station device to report sensing measurement results. The trigger frame may include one or more station identifiers, each of which identifies the one or more station devices. For example, the station identifier may be identified using an AID or UID, where an AID may represent an identifier of a station with which an associated communication has been established, and a UID may represent an identifier of a station with which an associated communication has not been established. For example, when an AP sends a trigger frame including one or more AIDs or UIDs to one or more STAs, the STA that receives the trigger frame may parse the trigger frame to determine whether its own AID or UID is included in the trigger frame. If the STA determines that the trigger frame includes its own AID or UID, the STA reports its sensing measurement results to the AP.

[0053] Although the information that may be included in the trigger frame is described separately in each of the above embodiments, it will be understood that various combinations of the above embodiments may be made.

[0054] For example, in an optional embodiment, in a communication method for perception measurement reporting provided by the present disclosure, the communication method can be applied to an access point device, a trigger frame includes a threshold value, the threshold value is set for each of one or more station devices, and the threshold value is also used to enable the one or more station devices to determine whether to report the perception measurement result; and the trigger frame can include a perception measurement establishment identifier. The threshold value (e.g., a CSI threshold value or a quantized CSI threshold value) can correspond to the perception measurement establishment identifier, thereby identifying the threshold value set for the perception measurement process corresponding to the corresponding perception measurement establishment identifier. For example, when threshold value B corresponds to a first perception measurement establishment identifier in the trigger frame, for the perception measurement process corresponding to the first perception measurement establishment identifier, if the perception measurement result measured by the station device that receives the trigger frame is greater than or equal to threshold value B, the station device reports (sends) the perception measurement result to the AP.

[0055] However, the present disclosure is not limited thereto, and the perception measurement establishment identifier may be omitted, or the threshold existence flag may be included in the trigger frame.

[0056] For example, in an optional embodiment, in a communication method for perception measurement reporting provided by the present disclosure, the communication method can be applied to an access point device, wherein a trigger frame includes a threshold value, which is set for each of one or more station devices, and the threshold value is also used to enable the one or more station devices to determine whether to report the perception measurement result; and the trigger frame can include one or more station identifiers. The station identifier (e.g., AID / UID) in the trigger frame can correspond to the threshold value (e.g., CSI threshold value or quantized CSI threshold value) in the trigger frame. For example, the threshold value (e.g., CSI threshold value or quantized CSI threshold value) set for each STA may be different. Assigning the threshold value to the STA's station identifier can enable the corresponding STA to clearly understand its own threshold value and report the perception measurement result to the AP when the perception measurement result of the corresponding STA is greater than or equal to its threshold value.

[0057] However, the present disclosure is not limited thereto, and the site identifier may also be omitted, or the threshold existence flag bit and / or the perception measurement establishment identifier may be included in the trigger frame.

[0058] The above embodiments describe various information included in a trigger frame. It will be understood that various modifications may be made to the above embodiments, and embodiments obtained by combining the above embodiments are also included in the scope of the present disclosure.

[0059] The communication method according to the embodiment of the present disclosure improves the mechanism of the threshold reporting method. For example, in the case of CSI threshold reporting, the format of the trigger frame sent by the AP is improved to make it suitable for WLAN awareness measurement.

[0060] According to embodiments of the present disclosure, various information included in a trigger frame may be included in various information fields within the trigger frame. For example, after receiving CSI feedback from a STA, if the AP finds that the CSI value is higher than a defined CSI threshold, the AP sends a trigger frame. For example, the common information field of the trigger frame includes at least one bit (such as the "threshold presence flag bit" described in the above embodiments) to indicate the presence of a CSI threshold or a quantized CSI threshold, thereby enabling the STA to report perception measurement results based on the CSI threshold or quantized CSI threshold. Furthermore, the common information field includes a perception measurement establishment identifier subfield, which identifies the specific perception measurement process for which perception measurement results need to be fed back. Furthermore, since the CSI threshold or quantized CSI threshold set for each STA may be different, the CSI threshold or quantized CSI threshold may be included in the site information (STA info) field of the trigger frame, and the STA's AID / UID may correspond to its CSI threshold or quantized CSI threshold, thereby indicating that the STA needs to report perception measurement results if the threshold is higher than the threshold. It will be understood that the embodiments described herein are merely exemplary and not limiting of the present disclosure, and that various information may be carried in a trigger frame in various other ways.

[0061] Figure 3 is a flowchart illustrating a communication method according to an example embodiment. Figure 3 The communication method shown is applicable to an access point device.

[0062] Reference Figure 3 In step 310, the AP may receive a first message frame from one or more station devices, respectively. The first message frame may include a flag indicating that the corresponding station device supports threshold-based perception measurement reporting. The flag in the first message frame may indicate the station device's capability to support threshold-based perception measurement reporting (e.g., support for CSI threshold feedback).

[0063] For example, step 310 may be performed with reference to Figure 1The described perception session establishment process or the perception discovery process is performed. For example, the first message frame may be a response frame to the perception session establishment frame (which may be referred to as the "perception session establishment frame") sent by the AP, and the site device may identify in the response frame that it supports CSI threshold feedback, and send a response frame (first message frame) to the AP. Specifically, during the perception session establishment process, the identification bit may be included in the form of an information element, or during the perception discovery process, the bit in the extended capabilities information element may be used to identify that it supports CSI threshold feedback. According to an embodiment of the present disclosure, the pre-identification of the CSI threshold capability information facilitates the order and accurate execution of WLAN perception measurements.

[0064] In addition, although not shown in the figures, as an optional embodiment, the unit (quantization ratio) used for quantization can also be negotiated during the perception session establishment process or the perception discovery process. For example, the AP and STA can pre-negotiate the quantization unit (quantization ratio) through the perception session establishment frame and the response frame, so that the CSI value can be quantized and the quantized CSI threshold can be set based on the quantization unit (quantization ratio) in the subsequent perception measurement reporting phase.

[0065] In step 320, the AP may receive values ​​(e.g., CSI values ​​or quantized CSI values) for feedback of channel properties from one or more station devices. In step 330, the AP may send a trigger frame to at least one of the one or more station devices based on at least one received value being greater than or equal to a threshold, thereby triggering the at least one station device to report a sensing measurement result. Figure 3 Steps 320 and 330 in the above may be operations performed in the perception measurement reporting phase, and their specific contents have been referred to in Figure 2 The embodiments and various modifications thereof are described in detail, and for the sake of brevity, repeated descriptions are omitted here.

[0066] Figure 4 is a flowchart illustrating a communication method according to an example embodiment. Figure 4 The communication method shown is applicable to an access point device.

[0067] Reference Figure 4 In step 410, the AP may send a second message frame to one or more station devices, where the second message frame is used to trigger the one or more station devices to send values ​​(e.g., CSI values ​​or quantized CSI values) for feedback of channel attributes. For example, the second message frame may be a trigger frame that triggers the station devices that receive the trigger frame to send CSI values ​​or quantized CSI values.

[0068] In step 420, the AP may receive values ​​(e.g., CSI values ​​or quantized CSI values) for feedback channel properties from one or more station devices. In other words, in response to the triggering of the second message frame (trigger frame) from the AP in step 410, the one or more station devices may send, for example, CSI values ​​or quantized CSI values ​​to the AP.

[0069] In step 430 , the AP may send a trigger frame to at least one of the one or more station devices based on at least one received value being greater than or equal to a threshold, to trigger the at least one station device to report a perception measurement result.

[0070] Figure 4 Steps 420 and 430 in the above may be operations performed in the perception measurement reporting phase, and their specific contents have been referred to in Figure 2 The embodiments and various modifications thereof are described in detail, and for the sake of brevity, repeated descriptions are omitted here.

[0071] In addition, although Figure 4 4. However, the present disclosure is not limited thereto. For example, step 410 may be omitted (ie, Figure 2 In this case, for example, the AP may periodically receive CSI values ​​or quantized CSI values ​​from one or more station devices to determine whether each station device needs to report a perception measurement result.

[0072] Figure 5 is a flowchart illustrating an interaction according to an example embodiment.

[0073] Figure 5 The embodiment shows a perception measurement phase (NDPA probing phase) and a perception measurement reporting phase (reporting phase).

[0074] Reference Figure 5In the NDPA detection phase, the initiator (i.e., AP) may send a Null Data Packet Announcement (NDPA) frame and a Null Data Packet Announcement (NDP) frame to responder 1 (i.e., the first site) and responder 2 (the second site) for responder 1 and responder 2 to perform perception measurements. For example, the NDPA frame may be used to identify channel occupancy and / or carry information about the NDP frame. For example, the NDP frame may be used for perception measurements, for example but not limited to, the NDP frame may include operating parameters required for performing WLAN perception measurements, such as the number of spatial streams, the operating bandwidth of the NDP frame, the long training field (LTF), the packet extension field (PE), etc. Although not shown, responder 1 and responder 2 may perform perception measurements to obtain CSI values ​​or quantized CSI values. In addition, in an embodiment of the present disclosure, the initiator that sends the NDPA frame and the NDP frame may also be referred to as the perception sender, and the responder 1 and the responder 2 that receive the NDPA frame and the NDP frame may also be referred to as the perception receiver 1 and the perception receiver 2.

[0075] Figure 5 The reporting phase may also be referred to as a threshold-based reporting phase, which may include a CSI reporting sub-phase and a measurement reporting sub-phase. Figure 5 The "SIFS (Short interframe space)" in the MPEG-4 video frame format may refer to the interval time between frames.

[0076] In the CSI reporting subphase, the initiator AP may send a sensing trigger A (eg, Figure 4 4), responder 1 and responder 2 may send frame B (ie, the second message frame in step 410) to the initiator AP in response to the sensing trigger A. Figure 2 Step 210, Figure 3 Step 320 and Figure 4 Frame B may include a trigger frame in step 420 of the response, where Frame B may include a value for feeding back channel properties (e.g., a CSI value or a quantized CSI value). For example, Frame B sent by responder 1 may include the CSI value or quantized CSI value of responder 1, and Frame B sent by responder 2 may include the CSI value or quantized CSI value of responder 2.

[0077] Although not shown, when the initiator AP receives frame B from responder 1 and responder 2, respectively, the initiator AP may compare the CSI value or quantized CSI value of responder 1 with a first threshold (a threshold set for responder 1) to determine whether responder 1 needs to feed back the perception measurement result; and may compare the CSI value or quantized CSI value of responder 2 with a second threshold (a threshold set for responder 2) to determine whether responder 2 needs to feed back the perception measurement result. As in the embodiment described above, the first threshold and the second threshold may be different CSI thresholds or quantized CSI thresholds set for responder 1 and responder 2, respectively, or the first threshold and the second threshold may be the same CSI threshold or quantized CSI threshold.

[0078] In the measurement report subphase, the initiator AP may send a perception trigger C based on the comparison result. In one embodiment of the present disclosure, the initiator AP may send a perception trigger C to the responder 1. For example, the initiator AP may send a perception trigger C to the responder 1 based on the CSI value or quantized CSI value of the responder 1 being greater than or equal to a first threshold (i.e., Figure 2 Step 220, Figure 3 Step 330 and Figure 4 (The trigger frame in step 430 of FIG4 is provided). Responder 1 may send a perception measurement report to the initiator AP in response to the perception trigger C. The perception measurement report may be a CSI threshold or a quantized CSI threshold of responder 1. That is, the initiator AP may determine a CSI threshold or a quantized CSI threshold for each responder for comparison with the CSI value or the quantized CSI value, but may not send the CSI threshold or the quantized CSI threshold to the responder.

[0079] In another embodiment of the present disclosure, the initiator AP may send a perception trigger C to responders 1 and 2, and the perception trigger C carries threshold information about responder 1 (e.g., a first threshold) and threshold information about responder 2 (e.g., a second threshold). Upon receiving the perception trigger C, responders 1 and 2 may obtain their respective thresholds and compare their perception measurement results (CSI values ​​or quantized CSI values) with the corresponding thresholds. For example, responder 1 may compare its perception measurement result (CSI value or quantized CSI value) with the first threshold and, if it determines that its perception measurement result (CSI value or quantized CSI value) is greater than or equal to the first threshold, send a perception measurement report to the initiator AP. For example, responder 2 may compare its perception measurement result (CSI value or quantized CSI value) with the second threshold and, if it determines that its perception measurement result (CSI value or quantized CSI value) is less than the second threshold, not send a perception measurement report to the initiator AP. That is, the initiator AP can determine the CSI threshold or quantized CSI threshold of each responder for comparison with the CSI value or quantized CSI value, and can send the CSI threshold or quantized CSI threshold to each sensing receiver through a trigger frame (sensing trigger C).

[0080] Will understand, Figure 5 The interactive flow chart shown is only an illustrative example and is not intended to limit the present disclosure.

[0085] In step 630, the STA may determine whether to send the perception measurement results to the access point device based on the trigger frame. For example, if the STA receives a trigger frame that does not carry a threshold, the STA may send the perception measurement results to the AP in response to the trigger frame. For example, if the STA receives a trigger frame that carries a threshold, the STA may parse the trigger frame to obtain the threshold set for it, compare the threshold with its perception measurement results, and determine whether to send the perception measurement results to the AP based on the comparison result. For example, if the STA's perception measurement result is greater than or equal to its threshold, the STA may determine in step 630 to send the perception measurement results to the AP; if the STA's perception measurement result is less than its threshold, the STA may determine in step 630 not to send the perception measurement results to the AP.

[0086] Alternatively, the trigger frame may include a threshold, wherein the threshold may be set (same or different) for each of the one or more site devices, and the threshold is used to enable the one or more site devices to determine whether to report the perception measurement result.

[0087] Optionally, the threshold of each site device may be a channel state information threshold or a quantized channel state information threshold.

[0090] Optionally, the trigger frame may include one or more site identifiers, wherein the one or more site identifiers may respectively identify one or more site devices.

[0091] The various information included in the trigger frame has been described above, and repeated description is omitted here to avoid redundancy.

[0092] Optionally, the communication method may further include (not shown): the STA sends a first message frame to the access point device, wherein the first message frame may include an identification bit for identifying that the station device supports threshold-based perception measurement reporting. This may be similar to the reference Figure 3 The embodiments described are relative to and with reference to Figure 3 The described embodiments are also applicable here, and repeated descriptions are omitted for brevity.

This may be similar to the reference Figure 4 The embodiments described are relative to and with reference to Figure 4 The described embodiments are also applicable here, and repeated descriptions are omitted for brevity.
