Description

Technical Field

[0001] This disclosure relates to the field of mobile communication technology. Specifically, this disclosure relates to a communication method, an electronic device, and a storage medium. Background Technology

[0002] With the rapid development of mobile communication technology, Wireless Fidelity (Wi-Fi) technology has made significant progress in terms of transmission rate and throughput. Currently, research on Wi-Fi technology focuses on areas such as 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, and its main applications include video transmission, Augmented Reality (AR), and Virtual Reality (VR).

[0003] Specifically, multi-band aggregation and coordination refers to devices communicating simultaneously in 2.4GHz, 5.8GHz, 6GHz, and other frequency bands. For scenarios where devices communicate simultaneously in multiple frequency bands, a new Media Access Control (MAC) mechanism needs to be defined for management. Furthermore, multi-band aggregation and coordination is expected to support low-latency transmission.

[0004] Currently, the maximum bandwidth supported by multi-band aggregation and coordination technology is 320MHz (160MHz+160MHz). In addition, it may also support 240MHz (160MHz+80MHz) and other bandwidths supported by existing standards.

[0005] Current Wi-Fi technologies under research may support Wireless Local Area Network (WLAN) sensing technologies. Examples include location discovery, proximity detection, and presence detection in dense environments (such as home and enterprise environments). During WLAN sensing, the roles of Station (STA) and Access Point (AP) devices are often interchangeable; both can act as Sensing Initiators or Sensing Transmitters. When acting as a Sensing Initiator or Sensing Transmitter, an AP can communicate with multiple STAs simultaneously, but STAs lack this capability and can only communicate one-to-one with a single Sensing Responder. This leads to wasted spectrum resources and increased latency, potentially failing to meet latency requirements in scenarios with high latency constraints. To address this issue, a method for WLAN sensing measurement using an AP-proxy STA, known as Sensing By Proxy (SBP), was proposed. The SBP initiator sends an SBP request to the SBP responder to initiate the SBP process. However, the SBP request is sent blindly, potentially preventing the SBP responder from establishing the SBP process, thus making the SBP request an invalid signaling message and wasting signaling resources. Therefore, a solution is needed to improve the SBP establishment mechanism. Summary of the Invention

[0039] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0040] This disclosure provides a communication method, electronic device, and storage medium, which solve the problem of SBP requests becoming invalid signaling messages, resulting in a waste of signaling resources.

[0041] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0042] like Figure 1 As shown in the illustration, this disclosure provides a communication method, which can optionally be applied to a first agent sensing measurement SBP response end, such as an access point device (AP); the method may include the following steps:

[0043] Step 101: Determine the target radio frame; wherein the target radio frame carries target parameter information for establishing SBP sensing measurement supported by the SBP responder; the target parameter information includes WLAN sensing measurement parameters supported by the site equipment of the SBP responder.

[0044] As a first example, see Figures 2 to 4 First, the architecture and process of WLAN Sensing applied to the proxy sensing measurement method provided in this disclosure embodiment will be introduced.

[0045] Figure 2 The diagram illustrates an architecture for a WLAN sensing process. The sensing initiator (or initiator terminal) initiates WLAN sensing (e.g., initiates a WLAN sensing session). Multiple sensing responders (or sensing receivers) may respond to this process, such as... Figure 2 The response terminals 1, 2, and 3 are shown in the diagram. When the sensing initiator initiates WLAN Sensing, multiple associated or unassociated WLAN Sensing response terminals can respond.

[0046] See Figure 3 The sensing initiator and the sensing responder communicate through a communication connection, as shown in communication connection S1; the sensing responders communicate with each other through communication connection S2.

[0047] In this context, each sensing initiator can be a client; each sensing responder (in this example, sensing responder 1 to sensing responder 3) can be a station (STA) or an access point (AP). Furthermore, STAs and APs can assume multiple roles in the WLAN sensing process; for example, an STA can act as a sensing initiator, which may be a sensing transmitter, a sensing receiver, or both, or neither. Similarly, a sensing responder can also be a sensing transmitter, a sensing receiver, or both.

[0048] As another architecture, such as Figure 4 As shown, both the sensing initiator and the sensing response end can be clients, and they can communicate by connecting to the same access point (AP) device. Figure 4 In this context, Client1 is the sensing initiator, and Client2 is the sensing response provider.

[0049] Typically, when acting as a Sensing Initiator or Sensing Transmitter, a STA does not have the ability to communicate with multiple receivers simultaneously. Therefore, a proxy device (such as an AP) is needed to perform sensing measurements based on triggered frame (TB) on behalf of the STA to improve the efficiency of sensing measurements.

[0050] During the SBP process, the SBP initiator sends an SBP request to the SBP responder to initiate the SBP procedure. However, the SBP request is sent blindly, and the SBP responder receiving the request may be unable to establish the SBP procedure, making the SBP request an invalid signaling message. For example, the SBP initiator may have parameter requirements for trigger-based sensing measurements, such as the number of sensing responders participating in the TB sensing measurement, the bandwidth of the sensing measurement, and the number of spatial streams supported by the sensing measurement. The SBP initiator can carry these sensing measurement parameter information in the SBP request frame to find a suitable SBP responder (AP) to establish the SBP sensing measurement. However, since the SBP request frame is sent blindly, the parameters fed back by the AP in the SBP response frame may not meet the requirements of the STA sensing measurement parameters. Therefore, the SBP sensing measurement cannot be established, resulting in the aforementioned invalid SBP request frame and SBP... All response frames become invalid signaling messages, reducing the efficiency of SBP sensing measurement establishment. In this embodiment, the first SBP responder determines the target radio frame, which carries target parameter information for establishing SBP sensing measurement supported by the SBP responder. The target parameter information includes WLAN sensing measurement parameters supported by site devices within the coverage area of ​​the SBP responder. That is, the first SBP responder informs the SBP initiator in advance of the target parameter information for establishing SBP sensing measurement supported by the SBP responder in the target radio frame. In this way, after receiving the target radio frame, the SBP initiator can select SBP responders that meet the SBP sensing measurement parameter requirements as target SBP responders based on the target parameter information carried in the target radio frame, and send SBP response frames to the target SBP responders, avoiding blind transmission of SBP response frames.

[0051] Optionally, the target wireless frame may include, for example, an association response frame or a reassociation response frame. The target parameter information includes WLAN sensing measurement parameters supported by STAs within the coverage area of ​​the SBP response terminal, such as the number of sensing response terminals supported by the STA, the minimum bandwidth for sensing measurement, and the minimum number of spatial streams (NSS) (received Rx and transmitted Tx) supported by the sensing measurement. These parameters can be identified using information elements, as shown in Table 1 below:

[0052] Table 1:

[0053]

[0054] The first SBP response end can broadcast the parameter information supported by each STA sensing measurement, and can carry the STA's identifier, such as the Association Identifier (AID) or Media Access Control (MAC) address.

[0055] Step 102: Send the target wireless frame.

[0056] The first SBP responder sends the target radio frame to the SBP initiator. After receiving the target radio frame, the SBP initiator selects target SBP responders that meet the SBP sensing measurement parameter requirements based on the target parameter information carried in the target radio frame and initiates SBP sensing measurement. The target SBP responder acts as an agent for the SBP initiator to initiate TB sensing measurement.

[0057] Furthermore, the SBP response end, acting as an SBP agent, initiates WLAN sensing measurements. The initiated WLAN sensing measurements are TB sensing measurements, which are divided into NDPA Sounding (downlink DL) sensing measurements and trigger frame Sounding (uplink UL) uplink sensing measurements.

[0058] WLAN sensing processes typically include both Triggered Based Sounding (TB) and Non-TB based sensing methods. Specifically, in TB sensing, the AP acts as the initiator or transmitter, while in Non-TB sensing, the STA acts as the initiator or transmitter. As a second example, the TB sensing measurement process is as follows: Figure 5 As shown, Figure 5 Multiple sensing measurement events of a TB sensing measurement process are shown; in Examples 1 to 5, the sensing measurement process includes polling, probing, and reporting (LTF sec.update) processes; in each example, probing may include only NDPA Sounding or TF Sounding; or it may include both, with the SBP initiator possibly participating in the NDPA Sounding process.

[0059] In this embodiment of the disclosure, the first SBP response terminal carries target parameter information for establishing SBP sensing measurement supported by the SBP response terminal in the target radio frame; the target parameter information includes the wireless local area network (WLAN) sensing measurement parameters supported by the site equipment of the SBP response terminal; the first SBP response terminal sends the target radio frame to the SBP initiator, so that after receiving the target radio frame, the SBP initiator can filter target SBP response terminals that meet the requirements of SBP sensing measurement parameters, send SBP response frames to the target SBP response terminals, establish effective SBP sensing measurement, avoid blind transmission of SBP response frames, and avoid invalid SBP sensing measurement.

[0060] See Figure 6 This disclosure provides a communication method, which can optionally be applied to a first agent sensing measurement SBP response end, such as an access point device (AP); the method may include the following steps:

[0061] Step 601: Determine the target radio frame; wherein the target radio frame carries target parameter information for establishing SBP sensing measurement supported by the SBP responder; the target parameter information includes: first parameter information for establishing SBP sensing measurement supported by the first SBP responder, and / or second parameter information for establishing SBP sensing measurement supported by the second SBP responder; the target parameter information includes WLAN sensing measurement parameters supported by the site equipment of the SBP responder.

[0062] Step 602: Send the target wireless frame.

[0063] The second SBP response terminal is an SBP response terminal within the coverage area of ​​the first SBP response terminal. The target radio frame sent by the first SBP response terminal includes parameter information for establishing SBP sensing measurement supported by the first SBP response terminal and / or the second SBP response terminal. In this way, the parameter information for establishing SBP sensing measurement supported by multiple SBP response terminals can be notified to the SBP initiator by sending the target radio frame through one SBP response terminal, without each SBP response terminal having to send it, thus saving signaling messages.

[0064] This disclosure provides a communication method, optionally applicable to a first agent sensing measurement SBP response terminal, such as an access point device (AP); the method may include the following steps:

[0065] A first radio frame is sent to the second SBP response terminal, the first radio frame instructing the second SBP response terminal to feed back the second parameter information supported by the second SBP response terminal for establishing SBP sensing measurement; wherein, the second SBP response terminal is an SBP response terminal within the coverage area of ​​the first SBP response terminal.

[0066] Receive the second parameter information fed back by the second SBP response terminal;

[0067] A target radio frame is determined; wherein the target radio frame carries target parameter information for establishing SBP sensing measurement supported by the SBP responder; the target parameter information includes: first parameter information for establishing SBP sensing measurement supported by the first SBP responder, and / or second parameter information; the target parameter information includes WLAN sensing measurement parameters supported by the site equipment of the SBP responder.

[0068] Send the target wireless frame.

[0069] Wherein, when the target parameter information includes the parameter information for establishing SBP sensing measurement supported by the second SBP response terminal, the first SBP response terminal broadcasts a second message frame to multiple second SBP response terminals within its coverage area, actively queries the second parameter information of the second SBP response terminals, receives feedback from the second SBP response terminals, and sends the feedback second parameter information in the target radio frame to the SBP initiator.

[0070] This disclosure provides a communication method, optionally applicable to a first agent sensing measurement SBP response terminal, such as an access point device (AP); the method may include the following steps:

[0071] Receive the second radio frame sent by the second SBP response terminal, and obtain the second parameter information carried in the second radio frame; the second parameter information includes the parameter information for establishing SBP sensing measurement supported by the second SBP response terminal;

[0072] A target radio frame is determined; wherein the target radio frame carries target parameter information for establishing SBP sensing measurement supported by the SBP responder; the target parameter information includes: first parameter information for establishing SBP sensing measurement supported by the first SBP responder, and / or second parameter information; the target parameter information includes WLAN sensing measurement parameters supported by the site equipment of the SBP responder.

[0073] Send the target wireless frame.

[0074] Wherein, when the target parameter information includes the parameter information for establishing SBP sensing measurement supported by the second SBP response terminal, multiple second SBP response terminals within the coverage area can actively send the second parameter information to the first SBP response terminal. The first SBP response terminal receives the feedback from the second SBP response terminal and sends the feedback second parameter information in the target radio frame to the SBP initiator.

[0075] In this embodiment of the disclosure, the site device includes an associated device with the SBP response end and a non-associated device that has completed the pre-association security negotiation with the site device; that is, the site device of the first SBP response end and / or the second SBP response end includes its associated device (association means establishing a communication connection) and non-associated device, the non-associated device being the device that has not performed pre-association security negotiation (PASN).

[0076] This disclosure provides a communication method, optionally applicable to a first agent sensing measurement SBP response terminal, such as an access point device (AP); the method may include the following steps:

[0077] When the non-associated device completes the pre-association security negotiation with the site device, the WLAN sensing measurement parameters supported by the non-associated device are carried in the target radio frame;

[0078] Send the target wireless frame.

[0079] For non-associated devices that have not established an initial association with the SBP responder, after the PASN process is completed, the first SBP responder carries the WLAN sensing measurement parameters supported by the non-associated device in the target radio frame and broadcasts the target radio frame, so that the SBP initiator can obtain the WLAN sensing measurement parameters.

[0080] This disclosure provides a communication method, optionally applicable to a first agent sensing measurement SBP response terminal, such as an access point device (AP); the method may include the following steps:

[0081] When the non-associated device completes the pre-association security negotiation with the site device, a third radio frame sent by the SBP initiator is received, the third radio frame indicating the acquisition of WLAN sensing measurement parameters supported by the non-associated device.

[0082] The target wireless frame is then sent by carrying the WLAN sensing measurement parameters supported by the non-associated device.

[0083] For non-associated devices that have not established an initial association with the SBP responder, after the PASN process is completed, the SBP initiator can actively query the WLAN sensing measurement parameters supported by the non-associated device by sending a third radio frame. The first SBP responder carries the WLAN sensing measurement parameters supported by the non-associated device in the target radio frame, so that the SBP initiator can obtain the WLAN sensing measurement parameters.

[0084] In an optional embodiment, the method further includes:

[0085] A first identifier bit is carried in the beacon frame or probe response frame, the first identifier bit indicating that the first SBP response end supports SBP sensing measurement;

[0086] and / or

[0087] The associated response frame carries a second identifier bit, which indicates that the beacon frame or probe response frame carries parameter information of the SBP sensing measurement supported by the first SBP response end.

[0088] The AP (SBP responder) can carry a first identifier bit in the beacon frame or probe response frame to indicate that it supports SBP sensing measurement; the first identifier can occupy 1 bit, for example, "1" indicates that it supports SBP sensing measurement.

[0089] The AP (SBP responder) can also carry a second flag bit in the associated response frame. The second flag bit indicates that the beacon frame or probe response frame carries parameter information of the SBP sensing measurement supported by the first SBP responder. The first flag bit can occupy 1 bit, for example, "1" indicates that it carries parameter information of the supported SBP sensing measurement.

[0090] In this embodiment of the disclosure, the first SBP response terminal carries target parameter information for establishing SBP sensing measurement supported by the SBP response terminal in the target radio frame; the target parameter information includes the wireless local area network (WLAN) sensing measurement parameters supported by the site equipment of the SBP response terminal; the first SBP response terminal sends the target radio frame to the SBP initiator, so that after receiving the target radio frame, the SBP initiator can filter target SBP response terminals that meet the requirements of SBP sensing measurement parameters, send SBP response frames to the target SBP response terminals, establish effective SBP sensing measurement, avoid blind transmission of SBP response frames, and avoid invalid SBP sensing measurement.

[0091] See Figure 7 This disclosure provides a communication method, optionally applicable to the agent-aware measurement SBP initiator, wherein the network device may be a site device (STA), and the method may include the following steps:

[0092] Step 701: Receive a target radio frame sent by the first SBP response terminal; wherein the target radio frame carries target parameter information for establishing SBP sensing measurement supported by the SBP response terminal; the target parameter information includes WLAN sensing measurement parameters supported by the site equipment of the SBP response terminal.

[0093] The architecture and process of the WLAN Sensing applied in the communication method provided in this embodiment refer to the first example above, and will not be repeated here.

[0094] Typically, when acting as a Sensing Initiator or Sensing Transmitter, a STA does not have the ability to communicate with multiple receivers simultaneously. Therefore, a proxy device (such as an AP) is needed to perform sensing measurements based on triggered frame (TB) on behalf of the STA to improve the efficiency of sensing measurements.

[0095] During the SBP process, the SBP initiator sends an SBP request to the SBP responder to initiate the SBP process. However, the SBP request is sent blindly, and the SBP responder that receives the SBP request may be unable to establish the SBP process, making the SBP request an invalid signaling message. For example, the SBP initiator may have parameter requirements for TB sensing measurements, such as the number of sensing responders participating in the TB sensing measurement, the bandwidth of the sensing measurement, and the number of spatial streams supported by the sensing measurement. The SBP initiator can carry this sensing measurement parameter information in the SBP request frame to find a suitable SBPresponder (AP) to establish the SBP sensing measurement. However, since the SBP request frame is sent blindly, the parameters fed back by the AP in the SBP response frame may not meet the requirements of the STA sensing measurement parameters. Therefore, the SBP sensing measurement cannot be established, causing both the aforementioned SBP request frame and SBP response frame to become invalid signaling messages, and reducing the efficiency of the SBP sensing measurement process establishment. In this embodiment, SBP... The initiator receives a target radio frame sent by the first SBP responder and obtains the target parameter information for establishing SBP sensing measurements supported by the SBP responder carried in the target radio frame. The target parameter information includes the WLAN sensing measurement parameters supported by the site equipment within the coverage area of ​​the SBP responder. That is, the first SBP responder informs the SBP initiator in advance of the target parameter information for establishing SBP sensing measurements supported by the SBP responder in the target radio frame. In this way, after receiving the target radio frame, the SBP initiator can select the SBP responder that meets the SBP sensing measurement parameter requirements as the target SBP responder according to the target parameter information carried in the target radio frame, and send an SBP response frame to the target SBP responder to avoid blindly sending SBP response frames.

[0096] Optionally, the target wireless frame may include, for example, an association response frame or a reassociation response frame. The target parameter information includes WLAN sensing measurement parameters supported by STAs within the coverage area of ​​the SBP response terminal, such as the number of sensing response terminals supported by the STA, the minimum bandwidth for sensing measurement, and the minimum number of spatial streams (NSS) (received Rx and transmitted Tx) supported by the sensing measurement. These parameters can be identified using information elements, as shown in Table 1 below:

[0097] Table 1:

[0098]

[0099] The first SBP response end can broadcast the parameter information supported by each STA sensing measurement, and can carry the STA's identifier, such as the Association Identifier (AID) or Media Access Control (MAC).

[0100] Step 702: Based on the target parameter information, initiate the agent sensing measurement process with the SBP response terminal.

[0101] After receiving the target radio frame, the SBP initiator selects the target SBP response terminals that meet the SBP sensing measurement parameter requirements based on the target parameter information carried in the target radio frame, and initiates SBP sensing measurement; the target SBP response terminal acts as an agent for the SBP initiator to initiate TB sensing measurement. The TB sensing measurement process is described in the second example above and will not be repeated here.

[0102] In this embodiment of the disclosure, the SBP initiator receives a target radio frame and obtains the target parameter information for establishing SBP sensing measurement supported by the SBP response terminal carried therein; based on the target parameter information, it initiates a proxy sensing measurement process with the SBP response terminal; after receiving the target radio frame, the SBP initiator can filter target SBP response terminals that meet the SBP sensing measurement parameter requirements, send an SBP response frame to the target SBP response terminal, establish a valid SBP sensing measurement, avoid blind transmission of SBP response frames, and avoid invalid SBP sensing measurements.

[0103] In an optional embodiment, the target parameter information includes: first parameter information for establishing SBP sensing measurement supported by the first SBP response terminal, and / or second parameter information for establishing SBP sensing measurement supported by the second SBP response terminal.

[0104] The second SBP response terminal is the SBP response terminal within the coverage area of ​​the first SBP response terminal.

[0105] In one alternative embodiment, the site device includes an associated device with the SBP response end and a non-associated device that completes the pre-association security negotiation with the site device.

[0106] In an optional embodiment, the method further includes:

[0107] When the non-associated device completes the pre-association security negotiation with the site device, it sends a third radio frame to the SBP response end. The third radio frame instructs the SBP response end to carry the WLAN sensing measurement parameters supported by the non-associated device in the target radio frame.

[0108] For non-associated devices that have not established an initial association with the SBP responder, after the PASN process is completed, the SBP initiator can actively query the WLAN sensing measurement parameters supported by the non-associated device by sending a third radio frame. The first SBP responder carries the WLAN sensing measurement parameters supported by the non-associated device in the target radio frame, so that the SBP initiator can obtain the WLAN sensing measurement parameters.

[0109] In an optional embodiment, the method further includes:

[0110] The association request frame carries a third identifier bit, which indicates that the SBP initiator supports SBP sensing measurement.

[0111] The STA (SBP initiator) can carry a third flag bit in the association request frame to indicate that it supports SBP sensing measurement; the third flag bit can occupy 1 bit, for example, "1" indicates that it supports SBP sensing measurement.

[0112] In this embodiment of the disclosure, the SBP initiator receives a target radio frame and obtains the target parameter information for establishing SBP sensing measurement supported by the SBP response terminal carried therein; based on the target parameter information, it initiates a proxy sensing measurement process with the SBP response terminal; after receiving the target radio frame, the SBP initiator can filter target SBP response terminals that meet the SBP sensing measurement parameter requirements, send an SBP response frame to the target SBP response terminal, establish a valid SBP sensing measurement, avoid blind transmission of SBP response frames, and avoid invalid SBP sensing measurements.
