In Wi-Fi sensing, changes caused by the movement of objects, pets, and people in the environment are detected by using CSI (channel state information) or Radar-based methods without the need for the detected object to wear any equipment.

[0004] In the existing wireless sensing technology, the initiator and responder of the sensing service need to obtain the CSI (channel state information) between the initiator and the responder by sending NDP (null data packet) dedicated to sensing measurement, and then obtain the sensing result by calculating the CSI.

[0005] In this way, both the initiator and the responder need to use a dedicated time period to sense the sending and receiving of NDP. Both parties need to interrupt the current business to perform wireless perception measurement, which affects business continuity on the one hand, and on the other hand, since the dedicated time period is occupied, the sending opportunities of the initiator and the responder are inevitably reduced, thereby reducing the throughput.

[0018] Where R and N represent decoupling factors; TX power represents transmit power; and Antenna Gain represents antenna gain.

Although the disclosure in the present invention is introduced according to one or several exemplary examples, it should be understood that each aspect of these disclosures can also constitute a complete technical solution separately. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

In order to facilitate the clear description of the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects.

They are only used for illustration and distinction of the description objects.

[0046] Figure 1 FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present invention. Figure 1 As shown, the communication system includes an access point AP and a terminal STA. It should be understood that Figure 1 This is only a schematic diagram of the architecture of the communication system. In the embodiments of the present invention, the number and type of devices in the communication system are not limited. For example, the communication system may include more terminals or access points. In addition, those skilled in the art will understand that according to the principles and functions described herein, the term "access point (AP)" according to the present application can also be used to describe an access port or any other device that can receive and transmit wireless signals within a network architecture. Therefore, the use of the access point is only exemplary.

[0047] Figure 2 A flow chart of a wireless sensing measurement method provided by an embodiment of the present invention. Figure 2 As shown, the wireless sensing measurement method includes the following contents:

[0048] 101. The STA sends a connection request message (such as an Association request message) to the AP, requesting to establish a connection with the AP. The message indicates whether to support the use of broadcast messages for wireless perception measurement.

[0049] For example, the connection request message includes a parameter PassiveSensingsupported, which is used to indicate whether the use of broadcast messages for wireless sensing measurement is supported. If it is set to 1, it indicates support, and if it is set to 0, it indicates no support. In this embodiment of the present invention, it is set to 1.

[0050] 102. The AP sends a connection response message (such as an Association response message) to the STA. If the AP itself supports using broadcast messages to perform wireless perception measurements, the connection response message includes a passive perception information element.

[0051] Specifically, after the AP receives the connection request message, if the parameter PassiveSensingsupported is included and its value is 1, if the AP itself does not support the use of broadcast messages for wireless sensing measurements, the parameter is ignored. If the AP itself supports the use of broadcast messages for wireless sensing measurements, the connection response message sent to the STA includes a passive sensing information element (passive sensing element information element) for setting parameters related to the use of broadcast messages for wireless sensing measurements. For example, the passive sensing element information element includes the following parameters:

[0052] RUs for sensing: one or more frequency resources that can be used for wireless sensing measurements;

[0053] TX power: transmit power;

[0054] Antenna Gain: Antenna gain.

[0055] Among them, RUs for sensing can be set to include the following parameters:

[0056] Element ID: information element identifier;

[0057] Length: information element length;

[0058] RU 1: The first frequency resource available for wireless sensing measurements;

[0059] …

[0060] RU n: the nth frequency resource available for wireless sensing measurement, n ≥ 1.

[0061] Among them, RU 1, ..., RU n can be set to include resource information indicating the frequency band used for wireless perception measurement, such as the resource block start number and end number, or the resource block start number and resource block length, or the subcarrier start number and end number, or the subcarrier start number and subcarrier wavelength, etc. can be used to indicate the frequency band used for wireless perception measurement. Further, RU 1, ..., RU n can also include beam information indicating the beam used for wireless perception measurement. For example, RU1, ..., RU n can be set to include the following parameters:

[0062] Start index: the starting number of the resource block;

[0063] End index: the end number of the resource block;

[0064] Azimuth: beam azimuth;

[0065] Elevation: beam height;

[0066] Azimuth beam width: The width of the beam in the azimuth dimension when the power is above 3dB;

[0067] Elevation beam width: The width of the beam in the height dimension when the power is above 3dB.

[0068] 103. The STA reads the broadcast message according to the passive sensing information element, and obtains the CSI by measuring according to the read broadcast message.

[0069] Specifically, after receiving the connection response message, the STA saves the passive sensing element information element. When the STA needs to perform wireless sensing measurement, if the RUs for sensing in the passive sensing element information element only indicates resource information, the frequency band used for wireless sensing measurement is determined according to the resource information (such as Start index and End index) indicated by it, the broadcast message is read according to the determined frequency band, and the CSI of the frequency band is obtained according to the read broadcast message measurement. If the RUs for sensing in the passive sensing element information element indicates resource information and beam information, the frequency band and beam used for wireless sensing measurement are determined according to the resource information (such as Start index and End index) and beam information (such as Azimuth, Elevation, Azimuth beam width, Elevation beam Width) indicated by it, the broadcast message is read according to the determined frequency band and beam, and the CSI of the frequency band and beam is measured according to the read broadcast message.

[0070] In some embodiments, after measuring and obtaining CSI, the STA can obtain the perception result according to the TX power and Antenna Gain of the passive sensing element information element. The specific calculation method can refer to the relevant prior art. Since the power of the AP to send the broadcast message is variable, and the configuration of the AP to the antenna is also variable, if the prior art is used for calculation, it may cause errors in the final perception result. Therefore, the embodiment of the present application provides a more accurate calculation method, which is as follows:

[0071] CSI_decouple is calculated based on the TX power and Antenna Gain of the passive sensing element information element, so that the CSI_decouple value is decoupled from the transmit power and antenna gain, and then the difference CSI_variation between unit times is calculated based on the decoupled value CSI_decouple, and feature extraction and classification recognition are performed based on CSI_variation to obtain the perception result. Among them, the decoupling of the CSI_decouple value from the transmit power and antenna gain refers to the normalization calculation of the original CSI value measured under different transmit powers or different antenna gains to eliminate the influence of transmit power or antenna gain on CSI. For example, the decoupling method can be:

[0072] CSI_decouple=(R×CSI) / ((RN)×(10log(TX power)+Antenna Gain)),

[0073] Among them, R and N represent the decoupling factors, which can be obtained experimentally.

[0074] It should be noted that other methods may also be used to calculate and obtain the CSI_decoupled from the transmit power and the antenna gain, as long as the CSI_decouple value is not affected by changes in the transmit power and the antenna gain.

[0075] Through decoupling calculation, when the AP's transmit power and antenna gain change, the CSI measured before and after the change can still be used to calculate CSI_variation. If decoupling calculation is not performed, CSI_variation is calculated based on the CSI obtained under the premise of different reflected power and / or different gain, which leads to errors in the final perception result.

[0076] Furthermore, if the AP needs to adjust the transmit power and / or antenna configuration, it includes the passive sensing configuration parameter in the broadcast message, which includes the following parameters:

[0077] Next beacon TX power: The transmit power of the next broadcast message. If adjusted, it is included, otherwise it is not included.

[0078] Next beacon Antenna Gain: The antenna gain of the next broadcast message, included if adjusted, otherwise not included.

[0079] The STA reads the broadcast message. If the Next beacon TX power or / and Next beacon Antenna Gain contained therein are different from the currently saved TX power or / and Antenna Gain values, then after the current measurement calculation is completed, the TX power or / and Antenna Gain values ​​are set to the Next beacon TXpower or / and Next beacon Antenna Gain values ​​read in the latest broadcast message, so that the STA uses the updated value to calculate CSI_decouple when measuring the broadcast message next time.

[0080] Furthermore, the AP may also send a message instructing to obtain a wireless perception measurement report to the STA, and obtain a measurement result or a perception result from the STA. An example is as follows:

[0081] 201. When the AP needs to obtain a sensing result, it sends a sensing report poll message, in which the receiving address of the message is set to a broadcast address so that all terminals connected to the AP can receive the message. The message includes a parameter result type for setting the type of measurement result to be obtained.

[0082] 202. After receiving the sensing report poll message, if the STA agrees to provide the wireless sensing measurement report to the AP, it sends a CTS to AP message to the AP to indicate that it agrees to provide the wireless sensing measurement report.

[0083] 203. After receiving one or more CTS to AP messages, the AP may obtain a wireless perception measurement report from the terminal in the following manner:

[0084] 1) A trigger message is sent to each terminal in turn, in which a wireless perception measurement report is indicated. After receiving the trigger message, if the terminal indicates to obtain the wireless perception measurement report, the terminal sends the wireless perception measurement report to the AP.

[0085] 2) Send a trigger message, where the receiving address of the trigger message is set to the broadcast address, and the trigger message includes parameters STA info 1, ..., STA info m (m is the number of CTS to AP messages received by the AP) set for each terminal. STA info 1, ..., STA info m may include the identifier of the terminal and indicate the resources for sending the wireless perception measurement report, such as including parameters AID and Special reuse, or including parameters AID and AllocatedRU, where AID is used to indicate the identifier of the terminal; Special reuse is a space division multiplexing parameter used to set the terminal to send on different spatial streams; AllocatedRU is an allocated resource used to set the terminal to send on different frequency bands.

[0086] After the STA receives the trigger message, if the STA info 1-m contained therein contains its own identifier, it sends a wireless perception measurement report on the specified spatial stream according to the spatial division multiplexing parameter Special reuse corresponding to the identifier, or sends a wireless perception measurement report on the specified frequency band according to the allocated resource parameter AllocatedRU corresponding to the identifier.

[0087] Optionally, the method for the AP to obtain the wireless perception measurement report from the STA may not include steps 201-202, but directly send a trigger message instructing to obtain the wireless perception measurement report to the STA. The STA may also actively report the wireless perception measurement report to the AP.

[0088] In some embodiments, the process of establishing a connection between STA and AP may be the same as the prior art, that is, the parameter PassiveSensingSupported may not be included in the connection request message, and the passive sensing element information element may not be included in the connection response message. The AP may send the passive sensing element information element to the STA through other messages, so that the STA performs wireless sensing measurements based on the passive sensing element information element. It may also be assumed that all devices support wireless sensing measurements using broadcast messages.

[0089] The embodiment of the present invention further provides a wireless perception measurement device, including a perception measurement module, wherein the perception measurement module is used to perform the following steps:

[0090] Receive a first message sent by an access point, wherein the first message includes resource information, and the resource information is used to indicate a frequency band used for wireless sensing measurement; read a first broadcast message according to the frequency band indicated by the resource information; and obtain channel state information CSI by measurement according to the first broadcast message.
