In addition, 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 features in the embodiments can be combined with each other.

The term "and / or" includes any and all combinations of one or more associated listed items.

[0027] Typically, the wireless sensing process includes multiple stages, such as discovery, negotiation, and measurement. In the wireless sensing process, the initiator initiates the wireless sensing process, and the responder responds to the wireless sensing process. After both parties coordinate the roles, parameters, and reporting methods for sending and receiving sensing signals, sensing measurements begin. The method for controlling wireless sensing measurements in an embodiment of the present invention includes the following:

[0028] 101. The access device and the terminal device negotiate the role setting of the perception process and the type of perception signal sending, and determine that the access device is the receiver of the perception data packet and the terminal device is the sender of the perception data packet.

[0029] Specifically, when the access device is the initiator of the perception process and the terminal device is the responder of the perception process, the access device and the terminal device negotiate the role setting of the perception process and the type of perception signal transmission, including:

[0030] The access device sends a sensing setup request message to the terminal device. The sensing setup request message includes parameters Sensing role, Sensing type, and Session ID. Sensing role indicates the role setting of the sensing process, Sensing type indicates the type of sensing signal sent, and Session ID indicates the identifier of the sensing process.

[0031] After receiving the perception establishment request message, the terminal device sends a perception establishment response message to the access device. The perception establishment response message includes parameters result code and Session ID, where the result code is used to indicate whether to agree to execute the perception process.

[0032] Optionally, after receiving the perception establishment response message, if the parameter result code included in the response message indicates consent to execute the perception process, the access device adds the value of the parameter TA in the perception establishment response message or the identifier of the terminal device corresponding to the parameter TA to the terminal device list. In this case, the trigger message is sent to one or more terminal devices in the terminal device list.

[0033] When the access device is the responder of the perception process and the terminal device is the initiator of the perception process, the access device and the terminal device negotiate the role settings of the perception process and the type of perception signal sent, including:

[0034] Receive a perception establishment request message sent by a terminal device, wherein the perception establishment request message includes a parameter Session ID, wherein the Session ID is used to indicate an identifier of a perception process;

[0035] Send a perception establishment response message to the terminal device, wherein the perception establishment response message includes parameters Sensingrole, Sensing type, result code and Session ID, wherein Sensing role is used to indicate the role setting of the perception process, Sensing type is used to indicate the type of perception signal sent, and result code is used to indicate whether to agree to execute the perception process.

[0036] Optionally, after receiving the awareness establishment request message, the access device adds the value of the parameter TA in the awareness establishment request message or the identifier of the terminal device corresponding to the parameter TA to the terminal device list. At this time, the trigger message is sent to one or more terminal devices in the terminal device list.

[0037] In some embodiments, the Sensing role includes parameters Receiver and one or more Transmitters, where Receiver is used to indicate the receiver of the perception data packet and is set to the address or identifier of the access device; Transmitter is used to indicate the sender of the perception data packet and is set to the address or identifier of the terminal device.

[0038] In some embodiments, the terminal device list includes parameters Session ID and Responder j profile, where Responder j profile is used to indicate information about the jth terminal device, 1≤j≤n, and n is the number of candidate terminal devices, each of which is a terminal device whose capability parameters indicate support for the perception process or support for receiving and measuring perception data packets. Optionally, Responder j profile includes parameters Address / AID and Role, where Address / AID is used to indicate the address or identifier of the terminal device, and Role is used to indicate the role of the terminal device in the perception process, and is set to indicate that the terminal device is the sender of the perception data packet.

[0039] In some embodiments, an access device and a terminal device exchange capability parameters indicating whether they support a perception process or whether they support receiving and measuring perception packets. In this case, the access device and the terminal device negotiate the role setting of the perception process and the type of perception signal transmission, wherein the terminal device is a candidate terminal device, and the candidate terminal device is a terminal device whose capability parameters indicate that it supports the perception process or supports receiving and measuring perception packets.

[0040] 102. If the access device and the terminal device determine that the perception signal transmission type is the triggered type, the access device sends a trigger message. After receiving the trigger message, the terminal device begins sending perception data packets. If the access device and the terminal device determine that the perception signal transmission type is the scheduled type, the access device does not send a trigger message. The terminal device begins sending perception data packets according to the transmission time determined during the negotiation phase (the access device and the terminal device negotiate the transmission time of the perception data packets through the perception process request and perception process response messages).

[0041] For example, the trigger message includes parameters TA, RA, Common info and at least one User info, where TA is used to indicate the address of the message sender, RA is used to indicate the address of the message receiver, Common info is used to indicate the public information of the trigger message, and User info is used to indicate the information of the terminal device.

[0042] In some embodiments, Common info includes parameters trigger type, SU / MU, and Session ID, where trigger type is used to indicate the trigger type, SU / MU is used to indicate whether it is multi-user mode, and Session ID is used to indicate the identifier of the perception process. User info includes parameters AID, Tx offset, and SS / RU information, where AID is used to indicate the identifier of the terminal device, Tx offset is used to indicate the offset of the sending time, and SS / RU information is used to indicate the spatial stream or resource unit information used to send the perception data packet. When the SU / MU value indicates single-user mode, Tx offset is set, and the Tx offset value set in each User info is different. When the trigger message contains only one User info parameter, RA is set to the address corresponding to the parameter AID; when the trigger message contains two or more Userinfo parameters, RA is set to the broadcast address.

[0043] After receiving the trigger message, the terminal device starts sending the perception data packet, which specifically includes:

[0044] If the SU / MU parameter value indicates single-user mode, the sensing packet transmission time T is determined based on the Tx offset parameter. After receiving the trigger message and waiting for T, the sensing packet is transmitted based on the spatial stream or resource unit indicated by the SS / RU information. For example, T is calculated as: T = M + Tx offset, where M is the preset duration.

[0045] If the parameter SU / MU value indicates multi-user mode, after receiving the trigger message and waiting for a preset time, the sensing data packet is sent according to the spatial stream or resource unit indicated by the SS / RU information.

[0046] 103. The access device receives the sensing data packet and measures it.

[0047] To better understand the present invention, the following describes the present invention in detail with reference to two specific embodiments. In the first embodiment, the initiator of the wireless perception process is an access device (AP), referred to as the Initiator AP, and the responder of the wireless perception process is a terminal device (STA) that responds to the wireless perception process request from the Initiator AP, referred to as the Responder STA. In the second embodiment, the initiator of the wireless perception process is a terminal device (STA), referred to as the Initiator STA, and the responder of the wireless perception process is an access device (AP) that responds to the wireless perception process request from the Initiator STA, referred to as the Responder AP.

[0048] When a terminal device (STA) is connected to an access device (AP), both parties will inform each other of their capability parameters regarding the perception process.

[0049] For example, the parameter dot11SensMeasurementImplemented can be set in the AP and STA. When the value of dot11SensMeasurementImplemented is true, the capability parameter SensingCapable is set to 1, indicating that the sensing process is supported, otherwise it is set to 0, indicating that the sensing process is not supported; or the parameters dot11SensTransmitterOption and dot11SensRecieverOption can be set; when the value of dot11SensTransmitterOption is true, the capability parameter sensingTXcapable is set to 1, indicating that sending of sensing data packets is supported, otherwise it is set to 0, indicating that sending of sensing data packets is not supported; when the value of dot11SensRecieverOption is true, the capability parameter sensingRXcapable is set to 1, indicating that receiving and measuring sensing data packets are supported, otherwise it is set to 0, indicating that receiving and measuring sensing data packets are not supported.

[0050] When a STA establishes a connection with an AP, it sends an Association Request message to the AP, which includes the STA's capability parameters. The AP then sends an Association Response message to the STA, which also includes the AP's capability parameters. The AP can select a STA with the SensingCapable capability parameter set to 1 as a candidate STA or a STA with the sensingRXcapable capability parameter set to 1 as a candidate STA.

[0051] In the first embodiment, the method for controlling wireless sensing measurements includes the following:

[0052] 1001. The Initiator AP sends a sensing setup request message to candidate Responder STAs, where there can be one or more Responder STAs. For example, the parameters included in the sensing setup request message are shown in Table 1.

[0053] Table 1

[0054]

[0055] Table 2 shows an example of Sensing role settings.

[0056] Table 2

[0057]

[0058]

[0059] 1002. After receiving the Sensing Setup Request message, the Responder STA sets the result code to "Accepted" if it agrees to proceed with the sensing process. If it disagrees, it sets the result code to "Refused." The Responder STA then sends a Sensing Setup Response message to the Initiator AP, containing the result code and session ID. The Responder STA can be one or more STAs. For example, the Sensing Setup Response message settings are shown in Table 3.

[0060] Table 3

[0061]

[0062] 1003. If the received Sensing type value is "trigger based", the Responder STA waits for the trigger message sent by the Initiator AP and starts sending sensing data packets. If the received Sensing type value is "SP" or "non trigger based", it starts sending sensing data packets according to the sending time determined in the negotiation phase.

[0063] 1004. After receiving the Sensing Setup Response message, if the Result Code parameter in the message is set to Accepted, the Initiator AP adds the value of the TA parameter in the Sensing Setup Response message to the responder list, or adds the AID of the STA corresponding to the TA parameter to the responder list. For example, the responder list settings are shown in Table 4.

[0064] Table 4

[0065]

[0066] Table 5 shows an example of Responder 1-n profile settings.

[0067] Table 5

[0068]

[0069] 1005. The Initiator AP sends a trigger message to instruct the Responder STA to send a sensing data packet. For example, the trigger message settings are shown in Table 6.

[0070] Table 6

[0071]

[0072]

[0073] Common info contains the following parameters:

[0074] 1) trigger type: set to "sensing data packet transmission", indicating sensing data packet transmission;

[0075] 2) SU / MU: When set to 1, it indicates multi-user mode, and when set to 0, it indicates single-user mode. Multi-user mode means that multiple users can send sensing data packets at the same time, and single-user mode means that only one user sends a sensing data packet in a period of time.

[0076] 3) Session ID: Set to the value of the Session ID received in the received sensing setup response message.

[0077] User info contains the following parameters:

[0078] 1) AID: A temporary identifier assigned by the Initiator AP after the Responder STA connects to the Initiator AP;

[0079] 2) Tx offset: Transmit time offset. This parameter is included when the SU / MU parameter value is 0, and the TX offset set in each User Info field is different. Or, when the SU / MU parameter value is 1, this parameter is set to null, meaning that the parameter is not set.

[0080] 3) SS / RU information: Information about the spatial stream or resource unit used to send the sensing data packet.

[0081] 1006. After receiving the trigger message, if the value of trigger type is "sensing data packet transmission", the responder STA performs the sensing operation according to the parameters in Common Info and User Info, as follows:

[0082] 1) If the SU / MU parameter value is 0, the responder STA determines its own perception packet transmission time based on the Tx offset parameter, calculated as: waiting time = SIFS + Tx offset. (Here, SIFS refers to the short inter-message interval. SIFS can also be replaced with other predefined durations. SIFS is the shortest time interval defined in the system. For example, when the perception service is defined as a higher priority, using SIFS can increase the probability of successful perception packet transmission. Other predefined durations may reduce the probability of successful packet transmission.) After waiting for SIFS + Tx offset, the responder STA sends the perception packet according to the spatial stream or resource indicated by the SS / RUinformation.

[0083] 2) If the SU / MU parameter value is 1, after receiving the trigger message, after waiting for the SIFS duration, the sensing data packet is sent according to the spatial stream or resource indicated by the SS / RU information. Similarly, SIFS can also be replaced by other predefined durations.

[0084] 1007. The Initiator AP receives the sensing data packet, measures and obtains CSI (channel state information), extracts features, and performs classification and comparison on the CSI data to obtain a sensing result.

[0085] In the second embodiment, the method for controlling wireless sensing measurements includes the following:

[0086] 2001. The Initiator STA sends a sensing setup request message to the Responder AP. There can be one or more Initiator STAs. For example, the parameters included in the sensing setup request message are shown in Table 7.

[0087] Table 7

[0088]

[0089] 2002. After receiving the Sensing Setup Request message, the Responder AP sets the Result Code to Accepted if it agrees to proceed with the sensing process. If it disagrees, it sets the Result Code to Refused. The Responder AP then sends a Sensing Setup Response message to the Initiator STA, containing the Result Code and Session ID. The Initiator STA can be one or more STAs. For example, the Sensing Setup Response message settings are shown in Table 8.

[0090] Table 8

[0091]

[0092] Table 9 shows an example of Frame body settings.

[0093] Table 9

[0094]

[0095]

[0096] Table 10 shows an example of Sensing role settings.

[0097] Table 10

[0098]

[0099] 2003. If the received Sensing type value is "trigger based", the Initiator STA waits for the trigger message sent by the Responder AP and starts sending sensing data packets. If the received Sensing type value is "SP" or "non trigger based", it starts sending sensing data packets according to the sending time determined in the negotiation phase.

[0100] 2004. After receiving the sensing setup request message, the responder AP adds the value of the TA parameter in the sensing setup request message to the responder list, or adds the AID of the STA corresponding to the TA parameter to the responder list. For example, the responder list settings are shown in Table 11.

[0101] Table 11

[0102]

[0103]

[0104] Table 12 shows an example of Responder 1-n profile settings.

[0105] Table 12

[0106]

[0107] 1005. The Responder AP sends a trigger message to instruct the Initiator STA to send a sensing data packet. For example, the trigger message settings are shown in Table 13.

[0108] Table 13

[0109]

[0110] Common info contains the following parameters:

[0111] 1) trigger type: set to "sensing data packet transmission", indicating sensing data packet transmission;

[0112] 2) SU / MU: When set to 1, it indicates multi-user mode, and when set to 0, it indicates single-user mode. Multi-user mode means that multiple users can send sensing data packets at the same time, and single-user mode means that only one user sends a sensing data packet in a period of time.

[0113] 3) Session ID: Set to the value of the Session ID received in the received sensing setup response message.

[0114] User info contains the following parameters:

[0115] 1) AID: A temporary identifier assigned by the Responder AP after the Initiator STA connects to the Responder AP;

[0116] 2) Tx offset: Transmit time offset. This parameter is included when the SU / MU parameter value is 0, and the TX offset set in each User Info field is different. Or, when the SU / MU parameter value is 1, this parameter is set to null, meaning that the parameter is not set.

[0117] 3) SS / RU information: Information about the spatial stream or resource unit used to send the sensing data packet.

[0118] 1006. After the Initiator STA receives the trigger message, if the value of the trigger type is "sensing data packet transmission", it performs the sensing operation according to the parameters in the Common Info and User Info, as follows:

[0119] 1) If the SU / MU parameter value is 0, the initiator STA determines its own perception packet transmission time based on the Tx offset parameter, calculated as: waiting time = SIFS + Tx offset. (Here, SIFS refers to the short inter-message interval. SIFS can also be replaced with other predefined durations. SIFS is the shortest time interval defined in the system. For example, when the perception service is defined as a higher priority, using SIFS can increase the probability of successful perception packet transmission. Other predefined durations may reduce the probability of successful packet transmission.) After waiting for SIFS + Tx offset, the initiator STA sends the perception packet according to the spatial stream or resource indicated by the SS / RUinformation.

[0120] 2) If the SU / MU parameter value is 1, after receiving the trigger message, after waiting for the SIFS duration, the sensing data packet is sent according to the spatial stream or resource indicated by the SS / RU information. Similarly, SIFS can also be replaced by other predefined durations.

[0121] 1007. The Responder AP receives the sensing data packet, measures and obtains CSI (channel state information), extracts features and performs classification and comparison on the CSI data to obtain the sensing result.

[0122] In an embodiment of the present invention, based on the same inventive concept as the above-mentioned method for controlling wireless perception measurements, an apparatus for controlling wireless perception measurements is further provided, which is applied to an access device and includes:
