Among the currently researched Wi-Fi technologies, a wireless local area network (WLAN) sensing technology may be supported, for example, in application scenarios such as location discovery, proximity detection, presence detection, and the like in dense environments (e.g., home environment and enterprise environment). In the process of WLAN sensing, identities of a station (STA) and an access point (AP) are usually interchangeable, for example, both can be used as an initiator (SensingInitiator or SensingTransmitter). Upon serving as the SensingInitiator or SensingTransmitter, the AP can communicate with multiple STAs at the same time, but the STA do not have the above functions and can only communicate with a single sensing responder one-to-one. On the one hand, it causes waste of spectrum resources, and on the other hand, it causes delay. For communication scenarios with high latency requirements, the latency requirements may not be met.
Embodiments of this disclosure provide a WLAN sensing method and apparatus, an electronic device, and a storage medium, so as to solve the problems of wasted spectrum resources and increased time delay caused by STAs serving as sensing initiators.
Herein, the method and the apparatus/device are conceived based on the same concept. Since the principle of solving problems of the method and the apparatus/device is similar, the embodiments of the apparatus/device and the method may be referred to each other, and the description will not be repeated.
As shown in
In step 101, a sensing session establishment initiation message frame sent by an initiator is received.
As a first example, referring to
Referring to
Herein, each sensing initiator may be a client; and each sensing responder (in this example, sensing responder 1 to sensing responder 3) may be a station (STA). STA can assume multiple roles in the WLAN sensing process. For example, in the WLAN sensing process, the sensing initiator may be a sensing transmitter, a sensing receiver, or both of them, or neither of them. In the WLAN sensing process, the sensing responder may also be a sensing transmitter, a sensing receiver or both of them.
As another architecture, as shown in
During the WLAN sensing process, the initiator (e.g., STA) can send a sensing session establishment initiation message frame to the AP, where the sensing session establishment initiation message frame is used to initiate a sensing session, and the sensing session establishment initiation message frame is, for example, “Sensing Session setup request”. The AP receives the sensing session establishment initiation message frame, and performs sensing measurement on behalf of the initiator according to the sensing session establishment initiation message frame.
In step 102, in response to the sensing session establishment initiation message frame, a WLAN sensing measurement is established with a first station STA.
The AP establishes the WLAN sensing measurement with the first station STA in response to the sensing session establishment initiation message frame, where the first STA is the responder of the sensing measurement. In this way, during the WLAN sensing process, when the initiator is an STA, although the STA cannot perform one-to-many communication with the responders, the one-to-many communication can be realized by the AP performing sensing measurement on behalf of the initiator, thereby reducing the wasted spectrum resources and delay caused by the STA serving as the initiator for WLAN sensing.
According to some embodiments of this disclosure, the AP receives the sensing session establishment initiation message frame sent by the initiator and establishes, in response to the sensing session establishment initiation message frame, the WLAN sensing measurement with the first STA. The WLAN sensing measurement is performed through the AP serving as a proxy of the initiator, thereby realizing one-to-many communication between the responder(s) and the STA as the initiator. Some embodiments of this disclosure solve the problems of wasted spectrum resources and increased time delay caused by STAs serving as sensing initiators.
As a second example, referring to
In step 1, the STA sends a sensing session establishment initiation message (sensing session setup request) to the AP.
In step 2, the AP feeds back an ACK message.
Thereafter, the AP executes steps 3-1 and 3-2 to establish WLAN sensing measurement with multiple STAs respectively (sensing measurement setup).
In step 4, the AP sends a sensing session establishment response (sensing session setup response) to the STA.
In step 5, sensing measurement is performed between the AP and multiple responders and a measurement report is generated (measurement procedure and measurement report).
In step 6, the AP sends the measurement report to the STA.
In some embodiments, after receiving the sensing session establishment initiation message frame sent by the initiator, the method includes:
After the AP receives the sensing session establishment initiation message frame, it feeds back the ACK message to the initiator. As shown in step 2 of
In some embodiments, the sensing session establishment initiation message frame includes first parameter information, and the first parameter information includes at least one of the following:
Herein, the bandwidth information indicates the bandwidth required for WLAN sensing measurement. For example, in the spectrum below 7 GHz, the bandwidth is 20 MHz, 40 MHz, 80 MHz, 160 MHz, 320 MHz, or the like; in the 60 GHz spectrum, the bandwidth is 2160 MHz, 4320 MHZ, 6480 MHz, 8640 MHz, or the like. The NSS indicates the number of spatial streams of WLAN sensing measurement, which identifies the number of spatial streams of NDP as sent or received, for example, NSS is 2, 3, or the like. The period information indicates the measurement period information of WLAN sensing measurement. The first timeout information indicates the time information for the AP to receive the feedback message, and the AP receives the feedback message within the time indicated by the first timeout information. Optionally, the above-mentioned parameter may come from indication of an upper-layer application. For example, it is about 20 seconds.
The second timeout information indicates timeout information for the AP to send the response message, and the AP sends the response message within the time indicated by the second timeout information, Optionally, the second timeout information may be set by the AP For example, it is 200 milliseconds. Optionally, the second timeout information is smaller than the first timeout information.
The sensing type information indicates whether the current WLAN sensing is uplink sensing or downlink sensing, that is, whether it is TB-based (based on triggered) sensing measurement or Non-TB (based on non-triggered) sensing measurement.
The first indication information indicates whether the initiator participates in the sensing measurement. In other words, the initiator can also participate in the WLAN sensing measurement.
In some embodiments, when the first parameter information includes the sensing type information, said establishing, in response to the sensing session establishment initiation message frame, the WLAN sensing measurement with the first STA includes:
Optionally, if the sensing type is downlink sensing, after the sensing measurement is completed, the initiator sends an NDPA (Null Data Packet Announcement) frame to each first STA, and sends an NDP to the first STA. Then, a trigger frame is sent to receive a measurement sensing feedback of the first STA; or the first STA feeds back the measurement sensing feedback according to the resource in the NDPA frame. If the sensing type is uplink sensing, after the sensing measurement is completed, the initiator sends an NDPA frame to each first STA and, then, sends the trigger frame to the first STAs respectively, so as to receive the NDP sent by the first STAs.
In some embodiments, when the first parameter information includes the first indication information, and the first indication information indicates that the initiator participates in the sensing measurement, then the first STA includes the initiator. As a third example, referring to
In step 1, the STA sends a sensing session establishment initiation message (sensing session setup request) to the AP.
In step 2, the AP feeds back an ACK message.
Thereafter, the AP executes steps 3-1 and 3-2 to establish WLAN sensing measurement with multiple STAs (STA1-STAn) respectively (sensing measurement setup).
Moreover, the AP executes step 3-3 to establish WLAN sensing measurement with the initiating STA.
In step 4, the AP sends a sensing session establishment response (sensing session setup response) to the STA.
In step 5, sensing measurement is performed between the AP and multiple responders and a measurement report is generated (measurement procedure and measurement report).
In step 6, the AP sends the measurement report to the STA.
In some embodiments, after establishing the WLAN sensing measurement with the first station STA, the method includes:
In some embodiments of this disclosure, the sensing session response may also be a sensing session establishment response (sensing session setup response), as shown in step 4 of
The sensing session response includes: a state identifier code, a time synchronization function parameter, and/or time information indicating the first STA to receive the measurement report.
Herein, the state identifier code (Status Code) is used to indicate a state of the AP.
For example, when the state identifier code is a first parameter value, it indicates that the AP accepts the sensing session establishment initiation message frame and the first parameter information. For example, the first parameter value being “11” indicates that the AP accepts the sensing session establishment initiation message frame, and receives parameter configuration of the STA in the first parameter information with respect to the sensing measurement.
When the state identifier code is a second parameter value, it indicates that the AP can perform the WLAN sensing measurement and the WLAN sensing measurement includes second parameter information. For example, the second parameter value being “10” indicates that the AP can perform WLAN sensing measurement, but carries other second parameter information, such as other parameter configurations that meet the parameter configuration requirements in the first parameter information. For example, if the bandwidth requirement in the first parameter information is 20M, and the bandwidth provided in the second parameter information is 40M, then the AP can perform WLAN sensing measurement and a new parameter configuration is provided.
When the status identifier code is a third parameter value, it indicates that the AP refuses to perform the WLAN sensing measurement. For example, the third parameter value being “00” indicates that the AP cannot perform WLAN sensing measurement, for example, the requirements of the first parameter information cannot be satisfied.
Optionally, the time synchronization function parameter (Time Synchronization Function, TSF) indicates the initiator to enter a power-saving (PS) state, and to receive the measurement report sent by the AP upon entering an awake state. The AP may need to feedback TSF parameter information to the STA, so that the STA can enter the PS state after receiving the ACK frame, and then wake up to receive the measurement report fed back by the AP.
In some embodiments, after sending the sensing session response to the initiator, the method includes:
In some embodiments, the sensing session establishment initiation message frame includes a first identifier of the sensing session establishment initiation message frame, which is used to identify the sensing session. Optionally, the first identifier may be an identifier of an upper-layer application (e.g., an APP).
In some embodiments, the AP is an associated AP or a non-associated AP of the initiator.
As shown in
According to some embodiments of this disclosure, the AP receives the sensing session establishment initiation message frame sent by the initiator and establishes, in response to the sensing session establishment initiation message frame, the WLAN sensing measurement with the first STA. The WLAN sensing measurement is performed through the AP serving as a proxy of the initiator, thereby realizing one-to-many communication between the responder(s) and the STA as the initiator.
As shown in
In step 701, a sensing session establishment initiation message frame is determined.
As a first example, referring to
In the WLAN sensing process, the initiator (e.g., STA) determines the sensing session establishment initiation message frame, where the sensing session establishment initiation message frame is used to initiate the sensing session, and the sensing session establishment initiation message frame is, for example, “sensing session setup request”. The initiator may send the sensing session establishment initiation message frame to the AP, and the AP receives the sensing session establishment initiation message frame and performs sensing measurement on behalf of the initiator according to the sensing session establishment initiation message frame.
In step 702, the sensing session establishment initiation message frame is sent to the AP, thereby indicating the AP to establish WLAN sensing measurement with the first STA.
The initiator sends the sensing session establishment initiation message frame to the AP, so that the AP establishes the WLAN sensing measurement with the first STA, which is the responder of the sensing measurement. In this way, during the WLAN sensing process, when the initiator is an STA, although the STA cannot perform one-to-many communication with the responders, the one-to-many communication can be realized by the AP performing sensing measurement on behalf of the initiator, thereby reducing the wasted spectrum resources and delay caused by the STA serving as the initiator for WLAN sensing.
According to some embodiments of this disclosure, the initiator determines and sends the sensing session establishment initiation message frame to the AP, thereby indicating the AP to establish the WLAN sensing measurement with the first STA. The WLAN sensing measurement is performed through the AP serving as a proxy of the initiator, thereby realizing one-to-many communication between the responder(s) and the STA as the initiator. Some embodiments of this disclosure solve the problems of wasted spectrum resources and increased time delay caused by STAs serving as sensing initiators.
In some embodiments, after said sending the sensing session establishment initiation message frame to the AP, the method includes:

Herein, the bandwidth information indicates the bandwidth required for WLAN sensing measurement. For example, in the spectrum below 7 GHz, the bandwidth is 20 MHz, 40 MHz, 80 MHz, 160 MHz, 320 MHz, or the like; in the 60 GHz spectrum, the bandwidth is 2160 MHz, 4320 MHZ, 6480 MHz, 8640 MHz, or the like. The NSS indicates the number of spatial streams of WLAN sensing measurement, which identifies the number of spatial streams of NDP (null data packet) as sent or received, for example, NSS is 2, 3, or the like.

Optionally, the above-mentioned parameter may come from indication of an upper-layer application. For example, it is about 20 seconds.
The second timeout information indicates timeout information for the AP to send the response message, and the AP sends the response message within the time indicated by the second timeout information, Optionally, the second timeout information may be set by the AP. For example, it is 200 milliseconds. Optionally, the second timeout information is smaller than the first timeout information.
The sensing type information indicates whether the current WLAN sensing is uplink sensing or downlink sensing, that is, whether it is TB-based sensing measurement or Non-TB sensing measurement.
The first indication information indicates whether the initiator participates in the sensing measurement. In other words, the initiator can also participate in the WLAN sensing measurement.
In some embodiments, when the first parameter information includes the first indication information, and the first indication information indicates that the initiator participates in the sensing measurement, then the first STA includes the initiator. Referring to
In some embodiments, after sending the sensing session establishment initiation message frame to the AP, the method includes:
The sensing session response includes: a state identifier code, a time synchronization function parameter, and/or time information indicating the first STA to receive the measurement report.
Herein, the state identifier code (Status Code) is used to indicate a state of the AP.
For example, when the state identifier code is a first parameter value, it indicates that the AP accepts the sensing session establishment initiation message frame and the first parameter information. For example, the first parameter value being “11” indicates that the AP accepts the sensing session establishment initiation message frame, and receives parameter configuration of the STA in the first parameter information with respect to the sensing measurement.
When the state identifier code is a second parameter value, it indicates that the AP can perform the WLAN sensing measurement and the WLAN sensing measurement includes second parameter information. For example, the second parameter value being “10” indicates that the AP can perform WLAN sensing measurement, but carries other second parameter information, such as other parameter configurations that meet the parameter configuration requirements in the first parameter information. For example, if the bandwidth requirement in the first parameter information is 20M, and the bandwidth provided in the second parameter information is 40M, then the AP can perform WLAN sensing measurement and a new parameter configuration is provided.
When the status identifier code is a third parameter value, it indicates that the AP refuses to perform the WLAN sensing measurement. For example, the third parameter value being “00” indicates that the AP cannot perform WLAN sensing measurement, for example, the requirements of the first parameter information cannot be satisfied.
In some embodiments, the time synchronization function parameter indicates the initiator to enter a power-saving (PS) state, and to receive the measurement report sent by the AP upon entering an awake state. The AP may feedback TSF parameter information to the STA, so that the STA can enter the PS state after receiving the ACK frame, and then wake up to receive the measurement report fed back by the AP.

According to some embodiments of this disclosure, the initiator determines and sends the sensing session establishment initiation message frame to the AP, thereby indicating the AP to establish the WLAN sensing measurement with the first STA.
