Description

Communication method, access point device, and site device Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, an access point device, and a station device. Background Art

[0002] Among the Wi-Fi technologies currently under research, wireless local area network (WLAN) sensing technology may be supported. For example, it can be used in application scenarios such as location discovery, proximity detection, and presence detection in dense environments (such as homes and enterprises). During WLAN sensing, the identities of station devices (STA) and access points (AP) are often interchangeable. For example, both can act as initiators (Sensing Initiator or Sensing Transmitter). When acting as a Sensing Initiator or Sensing Transmitter, the AP can communicate with multiple STAs simultaneously. However, the STA does not have this functionality and can only communicate one-to-one with a single responder (Sensing Responder). This wastes spectrum resources and increases latency, which may not meet the latency requirements of communication scenarios with high latency requirements.

[0003] To solve this problem, a method of using an AP to proxy STAs to perform WLAN sensing measurements, namely Sensing By Proxy (SBP) measurement, is proposed. During the SBP process, AP parameters may change; therefore, a method for updating SBP parameters is needed.

[0040] The embodiments of the present disclosure provide a communication method, an access point device, and a station device.

[0041] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0042] The access point device AP determines a first radio frame when a BSS parameter of a basic service set BSS in which the AP is located changes; the first radio frame identifies that the AP terminates the SBP process or terminates the TB perception measurement process, and the first radio frame includes an identifier of the terminated measurement session, a Measurement Session ID;

[0043] The first radio frame is sent to a non-associated station device U-STA.

[0044] In the above embodiment, the access point device determines a first radio frame when the BSS parameters change, and the first radio frame indicates that the AP terminates the SBP process (or terminates the TB perception measurement process). When the BSS parameters change, in order to prevent the U-STA from being unable to update the BSS parameters in a timely manner, the access point device directly sends the first radio frame to terminate the SBP process (or terminate the TB perception measurement process). After receiving the first radio frame, the U-STA terminates participation in the SBP process and the TB perception measurement process.

[0045] In combination with some embodiments of the first aspect, in some embodiments, sending the first radio frame to the non-associated site device U-STA includes:

[0046] The first radio frame is sent to a non-associated station device U-STA within an available time window (Availability Window) pre-negotiated with the SBP initiator.

[0047] In the above embodiment, the first radio frame is sent within the pre-negotiated Availability Window, so that the U-STA updates the BSS parameters in time.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, before determining the first radio frame, the method includes:

[0049] In the process of establishing an SBP with a non-associated site device U-STA, an SBP request frame sent by the U-STA is received; wherein the SBP request frame identifies that the U-STA participates in TB perception measurement, and the SBP request frame includes the Availability Window information.

[0050] In the above embodiment, during the process of establishing the SBP between the AP and the U-STA, the SBP request frame is used to identify the U-STA to participate in the TB perception measurement and negotiate the Availability Window information.

[0052] In the above embodiment, the SBP termination frame or the Sensing Measurement Termination frame is used to instruct the U-STA to terminate participation in the SBP process and the TB sensing measurement process.

Then, within the Availability Window, after sending the first radio frame to the non-associated site device U-STA, the AP does not send the sensing measurement result of the measurement session.

[0054] In the above embodiment, if the SBP initiator receives the Sensing Measurement Termination frame in the availability window and does not receive the SBP report fed back by the SBP responder (AP) before the BSS parameters change, the SBP initiator has terminated the TB sensing measurement process, and the AP has not reported this SBP report. The SBP is not completed, and the SBP responder does not need to send the sensing measurement results of the measurement session again.

[0055] In combination with some embodiments of the first aspect, in some embodiments, the first wireless frame includes the SBP termination frame. Then, within the Availability Window, before sending the first wireless frame to the non-associated site device U-STA, the AP sends the perception measurement results of the measurement session to the SBP initiator.

[0056] In the above embodiment, if the SBP initiator (U-STA) receives an SBP Termination frame in the availability window, the SBP responder (AP) must forward the SBP report frame before the BSS parameter change to the SBP initiator before this, so that the U-STA can obtain the SBP measurement result before terminating the SBP process or terminating the TB perception measurement process.

[0057] In combination with some embodiments of the first aspect, in some embodiments, the first wireless frame includes second identification information, and the reason why the second identification information identifies the AP terminating the SBP process or terminating the TB perception measurement process includes: whether the parameters of the BSS in which the AP is located have changed.

[0068] In combination with some embodiments of the second aspect, in some embodiments, the first wireless frame includes an SBP termination frame or a Sensing Measurement Termination frame.

[0069] In conjunction with some embodiments of the second aspect, in some embodiments, before receiving the first radio frame, the method includes:

[0070] During the process of establishing the SBP with the AP, an SBP request frame is sent to the AP; wherein the SBP request frame identifies that the U-STA participates in the TB perception measurement, and the SBP request frame includes the Availability Window information.

[0071] In combination with some embodiments of the second aspect, in some embodiments, the first wireless frame includes the Sensing Measurement Termination frame. Then, within the Availability Window, after the AP sends the first wireless frame to the non-associated site device U-STA, the AP does not send the sensing measurement result of the measurement session.

[0107] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0108] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0109] In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0110] Specifically, the station device 101 may be a terminal device or network device equipped with a wireless fidelity (WiFi) chip. Optionally, the station device 101 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.

[0111] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0112] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0113] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0114] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0115] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0116] FIG2 is one of the interactive schematic diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0117] In step 201, the site device 101 sends an SBP request frame to the access point device AP during the process of establishing an SBP with the AP; wherein the SBP request frame indicates that the U-STA participates in the triggered frame (Triggered Based Sounding, TB) perception measurement, and the SBP request frame includes the availability window information.

[0118] The site device is a non-associated site device U-STA of the AP.

[0119] During the process of establishing an SBP with an access point device AP, the station device (SBP initiator) sends an SBP request frame to the AP, requesting the access point device to initiate TB perception measurement on its behalf; wherein the SBP request frame identifies the U-STA's participation in the TB perception measurement, for example, setting the Sensing responder flag in the SBP parameters information element of the SBP request frame to 1, indicating its participation in the TB perception measurement, which includes Null Data Packet Announcement (NDPA, downlink) perception measurement and trigger frame (TF uplink) perception measurement, etc.; and in the SBP request frame, the station device negotiates with the access point device (SBP responder) an available time window Availability Window for performing the SBP process, TB perception measurement, and Sensing Measurement Termination termination process, and reporting SBP report and SBP Termination. Within the available time window, the U-STA is in the awake state.

[0120] In step 202, the access point device AP determines a first wireless frame when the BSS parameters of the basic service set BSS in which the AP is located change; the first wireless frame includes an SBP termination frame, the SBP termination frame identifies that the AP terminates the SBP process, and the SBP termination frame includes the identifier of the terminated measurement session, Measurement Session ID.

[0121] Among them, the station device is the unassociated station device (Unassociated-Station, U-STA) of the AP, that is, the U-STA has not established an association with the AP. During the SBP process, the BSS parameters of the BSS where the AP is located may change. The AP cannot control the behavior of the U-STA. If certain parameters of the BSS parameters change, the AP may not be able to control whether the U-STA participating in the perception measurement can timely update certain parameters of the BSS parameter changes. For example, after the U-STA hears the beacon frame broadcast by the AP, some parameters of the BSS may change during the establishment of the SBP; if the U-STA participates in the TB perception measurement in the SBP, it needs to understand the changes in these parameters. However, since the U-STA has not established an association with the AP, the U-STA may not receive the changed BSS parameters. For example, the AP sends updated BSS parameters to the associated STA through an association response frame or a reassociation response frame, and the U-STA may not receive it.

[0122] Therefore, when the BSS parameters change, the access point device determines the SBP termination frame, and the SBP termination frame indicates that the AP terminates the SBP process (or terminates the TB perception measurement process). The SBP termination frame includes the identifier of the terminated measurement session, Measurement Session ID, such as the measurement session in which the U-STA participates. That is, when the BSS parameters change, in order to prevent the U-STA from being unable to update the BSS parameters in a timely manner, the access point device directly sends an SBP termination frame to terminate the SBP process. After receiving the SBP termination frame, the U-STA stops participating in the SBP process and the TB perception measurement process.

[0123] In this way, when the BSS parameters change, the U-STA, acting as an SBP initiator and a sensing responder, obtains an SBPtermination frame and terminates its participation in the SBP process (or TB sensing measurement process). This avoids the need for the access point device to send a sensing Measurement Termination frame again to terminate the TB sensing measurement process in which the U-STA participates after sending an SBP termination frame, thereby reducing signaling waste.

[0124] It is understandable that in the embodiment of the present disclosure, the AP may not send the first radio frame (SBP Termination frame or Sensing Measurement Termination frame) within the Availability window, for example, if the AP knows that the U-STA has been in the awake state outside the Availability Window.

[0125] In addition, in the embodiment of the present disclosure, the first radio frame includes an SBP Termination frame or a Sensing Measurement Termination frame; wherein the Measurement Session ID in the SBP Termination frame is consistent with the Measurement Session ID in the Sensing Measurement Termination frame.

[0126] For U-STA, when the BSS parameters change, it can only receive one of the SBP Termination frame or the Sensing Measurement Termination frame. If the SBP Termination frame is received first, the TB sensing measurement process is automatically terminated; if the Sensing Measurement Termination frame is received first, the SBP process is automatically terminated. The U-STA needs to receive the beacon frame sent by the AP to obtain the new BSS parameter change information and establish SBP sensing measurement (which may include TB sensing measurement, such as the sensing responder bit is set to) or Non-TB sensing measurement with the AP again.

[0127] Optionally, the BSS parameters include at least one of a transmit power envelope (TPE) and a punctured channel. It is understood that in the embodiments of the present disclosure, the BSS parameters also include parameters other than TPE and punctured channel, which are not further described herein.

[0128] Step 203: Send the first wireless frame to a non-associated station device U-STA.

[0129] Optionally, the AP sends the SBP termination frame to the non-associated station device U-STA within an available time window Availability Window pre-negotiated with the SBP initiator.

[0130] Among them, when the U-STA initiates the SBP process as the SBP initiator and requests the AP to initiate the TB perception measurement process as the SBP responder, when the BSS parameters change, the U-STA as the SBP initiator also obtains the SBPtermination frame as the sensing responder, and terminates participation in the SBP process (or the TB perception measurement process of the SBP process); after the access point device sends the SBP termination frame, it is necessary to send the sensing Measurement Termination frame again to terminate the TB perception measurement process in which the U-STA participates, so as to reduce signaling waste.

[0131] In some embodiments, the first radio frame includes the SBP termination frame. Then, within the Availability Window, before sending the first radio frame to a non-associated site device U-STA, the AP sends the perception measurement result of the measurement session to the SBP initiator.

[0132] Among them, if the SBP initiator (U-STA) receives an SBP Termination frame in the availability window, the SBP responder (AP) must forward the SBP report frame before the BSS parameter change to the SBP initiator before this, so that the U-STA can obtain the SBP measurement result before terminating the SBP process or terminating the TB perception measurement process.

[0133] In some embodiments, the first radio frame includes second identification information, and the reason why the second identification information identifies that the AP terminates the SBP process or terminates the TB perception measurement process includes: whether the parameters of the BSS where the AP is located change.

[0134] The SBP termination frame may carry the termination reason so that the SBP initiator can listen to the beacon frame broadcast again by the AP (SBP responder). The format of the SBP termination frame is shown in Table 1 below.

[0135] Table 1:

[0136] As shown in Table 1, the second identification information is carried in the SBP termination control field of the SBP termination frame.

[0137] Furthermore, the format of the SBP termination control field is shown in Table 2 below;

[0138] Table 2:

[0139] The second identification information may be carried in a reserved field, that is, occupying a new bit in the reserved field.

[0140] FIG3 is a second interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the method includes:

[0141] In step 301, the site device 101 sends an SBP request frame to the access point device AP during the process of establishing an SBP with the AP; wherein the SBP request frame identifies that the U-STA participates in the triggered frame (Triggered Based Sounding, TB) perception measurement, and the SBP request frame includes the availability window information.

[0142] The site device is a non-associated site device U-STA of the AP.

[0143] During the process of establishing SBP with the access point device AP, the station device (SBP initiator) sends an SBP request frame to the AP, requesting the access point device to initiate TB perception measurement on its behalf; wherein, the SBP request frame identifies that the U-STA participates in the TB perception measurement, for example, the Sensing responder identification bit in the SBP parameters information element of the SBP request frame is set to 1, indicating that it participates in the TB perception measurement; and in the SBP request frame, the Availability Window is negotiated with the access point device (SBP responder) for the SBP process.

[0144] In step 302, the access point device AP determines a first radio frame when a BSS parameter of the basic service set (BSS) in which the AP is located changes. The first radio frame includes a Sensing Measurement Termination frame, which indicates that the AP terminates participation in the TB process (or terminates the SBP sensing measurement process). The Sensing Measurement Termination frame includes an identifier of the terminated measurement session, Measurement Session ID.

[0145] Among them, the site device is the U-STA of the AP, that is, the U-STA is not associated with the AP. During the SBP process, the BSS parameters of the BSS where the AP is located may change. The AP cannot control the behavior of the U-STA. If certain parameters of the BSS parameters change, the AP may not be able to control whether the U-STA participating in the perception measurement can timely update certain parameters of the BSS parameter changes. For example, after hearing the beacon frame broadcast by the AP, the U-STA establishes an SBP perception measurement with the AP. During the process of establishing the SBP, certain parameters of the BSS may have changed; if the U-STA participates in the TB perception measurement in the SBP, it is necessary to understand the changes in these parameters. However, since the U-STA has not established an association with the AP, the U-STA may not receive the changed BSS parameters. For example, the AP sends updated BSS parameters to the associated STA through an association response frame or a reassociation response frame, and the U-STA may not receive it.

[0146] Therefore, when the BSS parameters change, the access point device determines a Sensing Measurement Termination frame. The Sensing Measurement Termination frame indicates that the AP terminates the TB sensing measurement process (or terminates the SBP process). The Sensing Measurement Termination frame includes the Measurement Session ID of the terminated measurement session, such as the measurement session in which the U-STA participates. That is, when the BSS parameters change, in order to prevent the U-STA from being unable to update the BSS parameters in a timely manner, the access point device directly sends a Sensing Measurement Termination frame to terminate the TB sensing measurement process. After receiving the Sensing Measurement Termination frame, the U-STA terminates the TB sensing measurement process (or terminates the SBP process).

[0147] In this way, when the BSS parameters change, the U-STA, as the SBP initiator and the sensing responder, obtains the SBPtermination frame and terminates participation in the TB sensing measurement process (or terminates the SBP process); avoiding the need for the access point device to send the SBP termination frame and the sensing Measurement Termination frame to terminate the TB sensing measurement process in which the U-STA participates, thereby reducing signaling waste.

[0148] Optionally, the BSS parameters include at least one of a transmit power envelope (TPE) and a punctured channel. It is understood that in the embodiments of the present disclosure, the BSS parameters also include parameters other than TPE and punctured channel, which are not further described herein.

[0149] Step 303: Send the Sensing Measurement Termination frame to the unassociated station device U-STA within the available time window Availability Window pre-negotiated with the SBP initiator.

[0150] Among them, when the U-STA initiates the SBP process as the SBP initiator and requests the AP to initiate the TB perception measurement process as the SBP responder, when the BSS parameters change, the U-STA as the SBP initiator also obtains the Sensing Measurement Termination frame as the sensing responder, and terminates participation in the SBP process (or the TB perception measurement process of the SBP process); after the access point device sends the SBP termination frame, it is necessary to send the sensing Measurement Termination frame again to terminate the TB perception measurement process in which the U-STA participates, so as to reduce signaling waste.

[0151] In some embodiments, the first radio frame includes the Sensing Measurement Termination frame. Then, within the Availability Window, within the available time window pre-negotiated with the SBP initiator, after sending the first radio frame to the non-associated site device U-STA, the AP does not send the sensing measurement result of the measurement session.

[0152] Among them, if the SBP initiator receives the Sensing Measurement Termination frame in the availability window and does not receive the SBP report fed back by the SBP responder (AP) before the BSS parameters change, the SBP initiator has terminated the TB perception measurement process, and the AP has not reported this SBP report. This SBP is not completed, and the SBP responder does not need to send the perception measurement results of the measurement session again.

[0153] In some embodiments, the first radio frame includes second identification information, and the reason why the second identification information identifies that the AP terminates the SBP process or terminates the TB perception measurement process includes: whether the parameters of the BSS where the AP is located change.

[0154] The Sensing Measurement Termination frame may carry the termination reason so that the SBP initiator can listen to the beacon frame broadcast again by the AP (SBP responder). The format of the Sensing Measurement Termination frame is shown in Table 3 below.

[0155] Table 3:

[0156] In some embodiments, the first radio frame includes a Sensing Measurement Termination frame, and the second identification information is carried in a Measurement Session Termination control field of the Sensing Measurement Termination frame.

[0157] As shown in Table 3, the second identification information is carried in the Measurement Termination Control field of the SBP termination frame.

[0158] Furthermore, the format of the Measurement Termination Control field is shown in Table 4 below;

[0160] The second identification information may be carried in a reserved field, that is, occupying a new bit in the reserved field.
